Project Description February 5, 2001 Williams Fiber Optic L2000 -0045 - Shoreline Substantial Development Permit Andrew Livingston, Project Manager for Williams Communication Installation of Fiber Optic Cable for Telecommunication Services. The project is subject to Shoreline Substantial Development permit, as work will be performed within 200 feet of the Duwamish River. The fiber optic line is proposed to be attached to Tukwila International Boulevard bridge and after crossing the river it follows the western edge of the East Marginal Way and will be within 200 feet of the shoreline jurisdiction for approximately 1600 feet across from the South Boeing Access Road. Development Permit Manufacturing Industrial Center/Heavy (MIC/H) Minnie Dhaliwal Williams Communications proposes to install fiber optic cable from Portland, Oregon to Seattle, Washington. In the City of Tukwila, the fiber optic cable is proposed along Tukwila International Boulevard from South 152nd Street to Boeing Access Road, where it continues along East Marginal Way South up to the City limits. This shoreline substantial development permit is for the work to be performed within 200 feet of the Ordinary High Water Mark of the Duwamish River. There are two such areas along the route where work is performed within 200 feet of the Duwamish River: one where it is 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 1 j z z�, �w 6 JU .0 0: UO w= SQ w: w O, g ¢. z a. :E-- _ • Z 1, ZO- w uf O N° oI-. w —..

I. Along shorelines of the state on Lake Sammamish, no building shall be placed on lands below thirty -two and one -half feet mean sea level. King County Code (KCC) Section 25.16.160 Utilities: Utility facilities may be permitted in the urban environment provided: A. Utility and transmission facilities shall: 1. Avoid disturbance of unique and fragile areas; 2. Avoid disturbance of wildlife spawning, nesting and rearing areas; 3. Overhead utility facilities shall not be permitted in public parks, monuments, scenic recreation or historic areas. Response: The approved method of construction is boring. Erosion and sedimentation controls will be used to ensure minimal disturbance to the river. Much of the area adjacent to right -of -way is developed. If any areas are disturbed as a result of boring or for temporary workspaces, all such areas must be restored and re- vegetated immediately. Applicant provided analysis of wildlife present in the area and also identified methods to minimize any disturbances. Qualified 4 .n., .n,.vxrwMrk+frNi?±s+'?nMKNR L2000 -0045 - Shoreline Permit Williams Communications February 5, 2001 biologists will be retained to monitor construction activities within 200 feet of the Duwamish River. There are no overhead utilities proposed as part of this project. B. Utility distribution and transmission facilities shall be designed so as to: 1. Minimize visual impact; 2. Harmonize with or enhance the surroundings; 3. Not create a need for shoreline protection; 4. Utilize to the greatest extent possible natural screening. Response: The fiber optic cable will be placed underground by boring and not open trench method. The conduit will be attached under the bridge in a reinforced fiberglass casing. After crossing the river, it will be installed below ground along the western edge of the East Marginal Way South and will be within 200 feet shoreline jurisdiction for approximately 1600 feet across from the South Boeing Access Road. There is no visual impact as a result of this project as the cable is placed underground by boring. C. The construction and maintenance of utility facilities shall be done in such a way so as to: 1. Maximize the preservation of natural beauty and the conservation of resources; 2. Minimize scarring of the landscape; 3. Minimize siltation and erosion; 4. Protect trees, shrubs, grasses, natural features and topsoil from drainage; 5. Avoid disturbance of critical aquatic and wildlife stages. Response: All vegetation removed, as a result of construction activity must be restored to pre - project conditions. Since the method of construction is boring and not open trenching, the scarring of landscape will be minimized. The project will meet all King County Surface Water Design Manual requirements related to erosion and sedimentation control. Qualified biologist must be present during construction within 200 feet of the river. Prior to issuance of construction permit, applicant shall show exact details of the location, size and distance of proposed boring pits /staging areas in relationship to the river bank near the Tukwila International Boulevard bridge attachment. Construction method shall be addressed (barge, scaffolding etc.). All measures shall be utilized not to disturb the riverbank. Also, the applicant must provide a letter from a geo- technical engineer to assure that there will be no adverse impact to the riverbank during boring operations. If any area is disturbed, it must be restored and re- vegetated immediately. Particular attention must be paid to the 5 L2000 -0045 - Shoreline Permit Williams Communications February 5, 2001 north riverbank at the Tukwila International bridge and impacts minimized. If any impacts associated with boring operations are anticipated in that area, it must be re- vegetated and rehabilitated to provide an effective vegetative cover. D. Rehabilitation of areas disturbed by the construction and /or maintenance of utility facilities shall: 1. Be accomplished as rapidly as possible to minimize soil erosion and to maintain plant and wildlife habitats; 2. Utilize plantings compatible with the native vegetation. Response: At this time, no areas are identified that will need disturbed as a result of the construction of this project. However, if during construction, any areas are disturbed they must be restored and rehabilitated as soon as possible. Qualified biologists will be on site during construction within shoreline jurisdictions to ensure proper rehabilitation and restoration. E. Solid waste transfer stations shall not be permitted within the shorelines of the state. Response: No solid waste stations are associated with this fiber optic line project. IV.

J December 21, 2000 Public Works Department City of Tukwila 6300 Southcenter Blvd. Tukwila, WA 98188 -2544 Re: Williams Communications Permit Applications To Whom It May Concern: Willi ms 2121 MERIDIAN EAST SUITE 6 EDGEWOOD, WA 98371 (253) 568 -0844 (253) 943 -0285 fax ovv Os Williams Communications has decided to break our proposed fiber optic line project in,,040 the City of Tukwila into 3 parts. This letter is part of the submittal of the 3 different sections of which separate applications will be filed. We will also break out the construction drawings into three separate packets with each one representing a different section. These are the same drawings that have been submitted as a whole but have been divided into the separate sections. As we understand the way things stand in our negotiations with the city, there is no conflict with public works about the proposed construction method (directional bore) on the portion of the route depicted with the enclosed map hereafter called section one. Running northbound on Tukwila International Blvd. /SR 99 from 152 "d St. (southern city limits) to 130th St. (here we pick up an additional twelve 1 %2 inch conduits) Then continuing northbound on E Marginal Way from S. Norfolk St (here we drop off eight 1 1/z inch conduits) to the northern end of the city limits. Williams has submitted plans depicting an open trench north of Norfolk St. on E. Marginal Way but has agreed with public works staff that we will bore this section as well. It is Williams sincere desire to at least have some work approved by the city so that we may get started sometime soon after the first of the year. This is our main purpose in splitting this route up into separate sections. We understand that you are requesting additional info (pier review) for the shoreline portion of the build.(depicted on the route map labeled section two) And we are still hashing out trenching vs. directional boring for the middle portion of the proposed route.(depicted on the route map labeled section three) As we have explained many times in the past, Tukwila is the last municipality in which we have no permit. Williams has contractual obligations and is under time and budget constraints. Contractors are finishing up Seattle and will be mobilizing in the first week of January to start work in SeaTac. We wish to have section one permitted as soon as possible so that we may have some work in the city while our other issues are resolved. As outlined in our franchise agreement, Williams agreed to provide Tukwila with 2 1 1/2 inch conduits on Tukwila International Blvd. /SR 99 from 152nd St. to the Boeing Access Road. Williams verbally agreed to extend these conduits the entire length of the route if the city would allow us to open trench from just north of the Duwamish River Bridge to Norfolk St. and would get a permit to us within a specified period of time. That period of time is long past but we have had other unforeseen problems that has elongated the process for us. This is an additional 21,180 feet of duct that Williams has agreed to provide the city and has a rough cost of $50,000. Williams still plans to provide that additional duct to the city if public works agrees to let us open cut the areas that we have discussed. We have told public works staff on many occasions why we feel it is necessary to open cut this area. That is not to say that we can't bore it. Boring of this area with the additional duct can be accomplished but at much additional expense to Williams Communications. The machines required to do a bore of the size we need to accommodate the additional duct and maintain the running line in this sort of terrain are expensive to operate. This on top of the fact that a directional bore of this size requires more time than an open trenching operation and you get a substantial increase in cost to complete this portion of the project. Additionally, after having our construction people take a closer look at this portion of E. Marginal Way to determine how we would attack it if we have to bore it, and how far apart they thought we could space the bore pits, we Nv.N\�• thought of another problem. We will have to perform this portion of the construction at cks& I ° night to minimize disruption to the traffic in the area as we did for the same portion oft 1 Marginal in Seattle. Once one of those large rigs is in place, it will begin a pilot bore until L, the desired length is reached, then it must punch through once more before pulling a �r� N�� reamer back. Sometimes this process takes more than one working day to achieve the o length specified between bore pits. When the rig does not have to be moved, this can be achieved. However, in a situation where the rig must be moved at the end of each working period to open up the street to traffic, a decision will have to be made at some point during the night to complete the bore so as to be off of the ROW by the specified time in the morning. Our construction people feel that they may be able to achieve about 750 ft. between bore pits given our time constraints and the soil conditions that we have encountered on E. Marginal in Seattle. But Tukwila public works personnel must understand that this process must be field engineered and if trouble is encountered the possibility exists that the distance between bore pits could be much shorter. We again looked at the possibility of being underneath one of the sidewalks on either side, but the density of the foreign utilities makes it a risky proposition, and we once again concluded that our best route (path of least resistance) on E. Marginal way would be to be in the northbound travel lane. Again, let me reiterate that Williams will pay the trench mitigation fees, and although trenching is more physically disruptive, it would be much quicker and less disruptive to the community. In closing, Williams hopes to be able to at least get a permit for construction for the section one portion mentioned previously and depicted on the map labeled section one. Our contractors will be remobilizing Jan 3`d and it would help us maintain our schedule to have a portion of Tukwila ready soon afterwards. We would also like to work diligently at the beginning of the year to resolve our issues with the other portions of the build. I don't think we have too much to overcome and we would obviously not like to see any stop in construction. .:" +.Yrra4NJMF''•1Sr?.tsx'iacia!d.

Williams estimates the construction cost for the Tukwila portion of thc build at approximately S3 million. Considering that we will be working on ns more than 30% of the build at any given time and the fact that we will be performing restoration work as we go, we believe that $1 million is a fair amount for bond. Additionally, considering the type of work being performed, it is hard to imagine that more that $ 1 million of damage could possibly be done, This figure is in line with other perforsance bonds that Williams has posted with other municipalities even vrhen•.• the scope of work was more extensive than that being done in Tukwila.

The plan has been developed using the King County Surface Water Design Manual as a guideline. These steps should be considered the minimum requirements for compliance with Core requirement #5 of the King County Surface Water Design Manual, erosion and sediment control requirements. W Additional steps or controls may be required by the City of Tukwila depending on the site conditions encountered. Q� A majority of the proposed construction will occur within existing city streets and sidewalks. This reduces the amount of 0 00 exposed soil subjected to erosion. This also makes several of the requirements listed in the King County Surface Water W Design Manual impractical or infeasible. Listed below are the erosion and sediment control measures required and a brief J description of their application to the project. ~ u WO Clearing Limits: Prior to any site clearing or grading areas to remain undisturbed during project construction shall be delineated. Limited clearing and grading is anticipated for the project. Clearing, grading and sensitive area boundaries g will be marked at the Riverton Creek and Duwarnish River crossings. The proposed installation locations (i.e. sidewalks, road shoulders, and bridges) will reduce the amount of clearing limit marking that can be reasonably installed and 2 Ci maintained. The edge of the road right -of -way (ROW) is marked on the maps as a reference. All work will take place F— _ within this ROW. Silt fence and /or survey flagging will be used to mark disturbance Limits at sensitive resources. Silt ? (- fence will not be wired or stapled to trees. 1-- O W Cover Measures: Temporary and permanent cover measures shall be provided when necessary to protect disturbed areas. Temporary cover measures will include straw mulch or plastic sheeting for all soil piles. Disturbed areas will be 0 seeded and mulched or have metal plates installed, pavement, or concrete replaced to match surround conditions. Slopes 0 l and stockpiles 3H:1V or steeper will be covered if unworked for more than 12 hours during the wet season. Cover W — measures will be in place at the end of the working day. = lid � L- O Perimeter Protection: When necessary, perimeter protection to filter sediment from sheet flow shall be provided Z downstream of all disturbed areas. Because of the narrow ROW, and surrounding conditions (roads, sidewalks, parking U to lots) perimeter protection installation will be limited to areas where it can be properly installed. H H O Traffic Area Stabilization: Unsurfaced entrances, roads, and parking areas used by construction traffic shall be Z stabilized to minimize erosion and tracking of sediment offsite. No new construction entrances should be needed for access to the ROW. Existing paved roads and parking lots should provide adequate access to the ROW. Any soil that is tracked from the work area onto paved surfaces will be immediately swept up. Under no circumstances will sediment tracked onto paved areas be washed into storm drains. Sediment Retention: Surface water collected from disturbed areas of the site shall be routed through a sediment pond or trap prior to release from the site. The limited size of the ROW will reduce the amount of surface water that will be encountered. It also prevents or severely limits the space available for the construction of sediment ponds and traps. The exception will be at horizontal directional bore locations. The pits excavated for this operation will also be used for sediment retention. All horizontal directional bore fluid (mud), cuttings and sediment collected in the pits will be removed with a vacuum truck and disposed of at approved locations. Surface Water Controls: Surface water controls shall be installed to intercept all surface water from disturbed areas, convey it to a sediment pond or trap, and discharge it downstream of any disturbed areas. As noted above the limited size of the ROW will reduce the amount of surface water and make it impractical to install effective surface water controls. All existing surface water controls (curbs, gutters, storm drains) will be maintained, repaired or replaced during construction. Catch basin inserts will be installed at all storm drain inlets that could potentially drain the construction area. Dust Control: Preventative measures to minimize wind transport of soil shall be implemented when a traffic hazard may be created or when sediment transported by wind is likely to be deposited in water resources. The wind transport of soil will be prevented by covering or watering the exposed soil. REQUIREMENTS Wet Season requirements: For construction that occurs from October 1 through April 30, the following will be considered the minimum requirements for compliance with this Erosion and Sediment Control Plan. More stringent requirements may be required by the City of Tukwila depending on the actual site conditions encountered. • Install temporary cover measures on all areas which will remain unworked for more than two days. • Install temporary cover measures on all stockpiles and steep cut and fill slopes if unworked for more than 12 hours. • Stockpile onsite a quantity of cover measure materials sufficient to cover all disturbed areas. • Temporarily seed and mulch all areas that will be unworked during the wet season (by October 8). • Apply and maintain (reapply) mulch to all seeded areas. Mulch will be maintained at 2 -3 inches of thickness. • Stabilize all construction traffic areas, unless already graveled. • 50 feet of silt fence per acre of disturbance must be stockpiled onsite. Sand bags filled with pea gravel, in a quantity sufficient for use with the silt fence, must also be stockpiled onsite. ■ Sediment retention is required unless no offsite discharge is anticipated. ■ Surface water controls are required unless no offsite discharge is anticipated. • Phasing of construction and more conservative BMP's must be evaluated for construction activity near surface waters. • Discharge from dewatering will be treated by sediment traps. • Maintenance reviews will be conducted weekly. Maintenance and Inspection: Williams and their contractor(s) will regularly inspect and maintain all erosion and sediment control devices to ensure proper functioning. At a minimum Williams and their contractor(s) will: • Establish an inspection schedule (weekly inspection is required during wet season) • Maintain all structures in good working condition and make needed repairs immediately • Repair, replace, restore all structures and protective devices damaged • Monitor downstream drainage features (remove deposited sediment -only with City approval) • Maintain all road and storm water drainage systems Installation timing: ■ Install on downstream/downhill side of work site prior to disturbance • Notify public works department within 48 hours of installation • Install permanent structures /devices prior to removing temporary devices Erosion and Sediment Control Devices: Refer to the attached typical drawings for installation requirements.

RECEIVED NOV 2 0 2000 TUKWILA PUBLIC WORKS Standard ESC Plan Notes : (From King County Surface Water Design Manual) 1. Approval of this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainage design (e.g., size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.) 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The applicant/ESC supervisor shall maintain the clearing limits for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall bee upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g., additional sump pumps, relocation of ditches and silt fence, etc.) 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). 8. Any area needing ESC measures that do require immediate attention shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within forty eight (48) hours following a storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment -laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and be maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above final grade of the permanent facility. 13. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1) all disturbed areas shall be reviewed to identify which ones can bee seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the DDES inspector. The DDES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. IRECF NOV ► j 2000 TUKWILA PUBLIC WORKS Construction Sequence: A detailed construction sequence is needed to ensure erosion and sediment controls are applied at the appropriate times. Recommended sequence 1. Hold pre- construction meeting 2. Flag or fence clearing limits prior to disturbance at sensitive resources or where clearing is anticipated. 3. Install catch basin protection, if required. 4. Install perimeter protection (silt fence, straw bales, etc.) 5. Maintain erosion control measures in accordance with City of Tukwila standards and manufacturer's recommendations. 6. Relocate surface water controls or erosion control measures, or install new measures so that as site conditions change, the erosion and sediment control is always in accordance with the City of Tukwila standards. 7. Cover all areas that will be unworked for more than seven days during the dry season or two days during the wet season with straw, wood fiber mulch, compost, plastic sheeting or equivalent. 8. Stabilize all areas within seven days of reaching final grade. 9. Seed or sod any areas to remain unworked for more.than 30 days. 10. Upon completion of the project, stabilize all disturbed areas and remove BMP's if appropriate and approved by City of Tukwila.

Our database does not give names for drainage resource numbers D- DESMO- 23N4E10 -1 and D- DESMO-23N4E9-1. We called them "unnamed tributaries" to the Duwamish River. Mr. Partee says that they are Riverton Creek and Southgate Creek, respectively, and would like us to refer to them using those names. Mr. Partee repeated his concern that we could not adequately address impacts to salmonids when we were uncertain of their presence. I asked him for information regarding salmonid presence in Riverton Creek. I also asked Mr. Partee what his rationale was for giving Riverton Creek a City of Tukwila Type 1 rating. [ Note: City of Tukwila ratings differ from DNR ratings. We had rated it Type 2, using Tukwila's 0 -33 point scoring system. We scored it in the 11 -20 point range, which corresponds to Type 2.] He said that he had given it a score of 19 originally (Type 2), due to the relatively large proportion of undeveloped land upstream and generally good corridor quality. However, he conducted electroshock surveys and found cutthroat trout in the stream, which adds 6 points to the total (25), making it a Type 1 stream. I asked him to send me some documentation of his finding. He agreed to e- mail a memo to me. I said that I would review it, and that we would advise Williams of the change in stream type. I clarified for Mr. Partee that Table 1 on page 11 of the Wetland and Stream Assessment Report (J &S, March 2000) contains only streams that have ground - breaking and/or construction corridor impacts within the stream buffer. Stream 2 (D- DESMO- 23N4E9 -1, Southgate Creek) has no impacts to its buffer, and hence was not listed in Table 1. I expect the e-mail from Mr. Partee by the end of the week. 2820 Northup Way, Suite 100 • Bellevue, WA 98004 -1419 • tel. 425 822.1077 • fax 425 822.1079 www.jonesandstokes.com z =z 00 co WI W0 2 gQ CD z d. �W z� F- 0 z I--' ui W 2 0 O �, 0 F— WW ■-- • 0 z` U =.

This fork is the northern open channel under crossing of Pacific Hwy South. During the survey, I located 3 cutthroat trout. The presence of trout in this area of Riverton Creek has changed the previous stream type rating for this section from a Type 2 to a Type 1. Type 2 streams within the City of Tukwila have a 35 foot buffer, Type 1 have a 70 foot buffer. Please let me know if there is anything else that I can provide . for you.

Nonwater related development and residential development shall Unot o perP 1Mtee T waterward of the ordinary high water mark Within the City of Tukwila, the fiber optic line will be placed underground by the open trench method and will be attached to the East Marginal Way overpass. The conduit will be attached under the bridge in a reinforced fiberglass casing. After crossing the river, the fiber optic line will be installed below ground along the western edge of the East Marginal Way South road prism and will be within the 200 -foot shoreline jurisdiction for approximately 1,600 feet across from the South Boeing Access Road. There will be no structures or accessory facilities located over the river. B. Except in those cases when the height requirements of the underlying zones are more restrictive, no structure shall exceed a height of thirty-five feet above average grade level. This requirement may be modified if the view of a substantial number of residences will not be obstructed, if permitted by the applicable provisions of the underlying zoning, and if the proposed development is agricultural, water related or water dependent. The fiber optic line will be placed belowground in previously disturbed right -of -way (ROW) along the route. The line marker posts are the only visible aboveground features of the underground fiber optic line installation project. These will be placed approximately 500 feet apart to alert people of the presence of the line. The markers are typically 4 -feet tall, 3.5 -inch diameter round PVC posts with embossed lettering. In public ROWs, line marker discs will be used instead of line marker posts and will be applied to the curbs with epoxy. No structures are associated with the project in the City of Tukwila. C. All development shall be required to provide adequate surface water retention and sedimentation facilities during the construction period. Best Management Practices (BMPs) will be used to minimize the potential for sediment transport to surface waters during and following installation of the fiber optic line. A Stormwater Pollution Prevention Plan (SWPPP) has been prepared for the project, including detailed descriptions of typical BMPs, and when and how they are to be applied. A copy of the SWPPP will be submitted to the contractor prior to the start of construction. BMPs and erosion control measures for this project will be used to isolate active construction areas from surface waters, and to minimize the sediment concentration of surface runoff. Environmental monitors will coordinate with construction crews to ensure that all necessary BMPs are followed and erosion control measures are installed and functioning properly.

All maintenance materials, oils, grease, lubricants, antifreeze, and similar materials will be stored offsite in staging areas. If these materials were required during field operations, they will be placed in a designated area away from site activities and sensitive resources. The equipment used for the proposed fiber optic line will need periodic maintenance and refueling. These activities will be accomplished responsibly, using the prescribed spill prevention countermeasures. No refueling or servicing will be done without absorbent material or drip pans underneath to contain spilled fuel. Any fluids drained from the machinery during servicing will be collected in leak -proof containers and taken to an appropriate disposal or recycling facility. If these activities result in damage to or accumulation of a product on the soil, it will be assessed and disposed of properly. Under no circumstances will knowingly contaminated soils be added to a spoils pile. Williams Communications, Inc.

Utility facilities may be permitted in the urban environment subject to the general requirements section (Section 25.16.030) of this chapter, provided: A. Utility and transmission facilities shall: 1. Avoid disturbance of unique and fragile areas; 2. Avoid disturbance of wildlife spawning, nesting and rearing areas; 3. Overhead utility facilities shall not be permitted in public parks, monuments, scenic recreation or historic areas. Construction avoidance windows have been identified to minimize and avoid sensitive resources during critical times. Erosion and sediment controls will be used to ensure minimal disturbance to the river. Revegetation, where appropriate, will occur as soon as possible to minimize changes to these fish and wildlife species habitat as well as minimize corridor fragmentation. Wildlife species potentially present in the project ROW include: Bald Eagle, Osprey, Vaux's swift, Great blue heron, Cavity nesting ducks, Pileated woodpecker, Waterfowl, Townsend's big -eared bat, Western pond turtle, Oregon spotted frog, Western toad, and Valley silverspot. The following measures have been developed to avoid or minimize potential impacts to wildlife from implementation of the proposed project: Reptiles and amphibians At seasonal streams that support suitable habitat for non - federally listed special status amphibians and reptiles where drilling is infeasible, impacts will be avoided initially by determining the presence or absence of these species, followed by constructing barrier fencing, and relocating individual animals during construction. General wildlife Retain qualified biologists and resource specialists to monitor construction activities near specified sensitive biological areas. • Fill or cover open trenches. Any open trenches will be filled with earth material or covered with plywood or other material to prevent entrapment of wildlife at the end of each workday. Both ends of any open trench will be sloped to form escape ramps before covering. If wildlife is found in the trench, they will be removed by a biological monitor before resumption of work in that trench segment. Williams will specify this requirement in the agreements with all construction contractors. Bald eagle • No construction activity will occur within 2,600 feet of an open nest or 1,300 feet of a screened nest between January 1 and August 15, unless individual consultation with a Washington Department of Fish & Wildlife (WDFW) biologist determines that the buffer can be reduced.

The shoulder of the road is typically 10 to 15 feet wide, with conifers, Z pastures, greenbelts, and landscape shrubs encroaching intermittently. Common upland o plants along this portion of the ROW include red alder, Himalayan blackberry (Rubrus w discolor), and reed canarygrass (Phalaris arundinacea). • o U cn One wetland occurs along this portion of the ROW, containing a mix of native and o F—. introduced plants, including black cottonwood (Populus balsamifera), cattail (Typha = v latifolia), reed canarygrass, and Himalayan blackberry. Reed canarygrass is classed as a o LI Weed of Concern by the King County Noxious Weed Control Board, with control - z recommended but not required. o — O '; City of Tukwila Fisheries Biologist Ryan Partee identified cutthroat trout in Riverton Z Creek, and changed the designation for the stream from Type 2 to Type 1. Stream 2 (D- DESMO-23N4E9-1) is a Type 2 stream. Fish presence was unknown in this stream. However, the culvert under the highway is approximately 15 feet above the water surface, presenting a complete barrier to upstream migration. Thus only resident species such as cutthroat trout would be expected at the construction site. Fish presence in the Duwamish River include all five species of Pacific salmon, as well as steelhead, rainbow, and cutthroat trout and other non -game species. Bull trout are occasionally present, but no self - sustaining populations are present in the Green River. The fiber optic line project has no overhead utility facilities. B. Utility distribution and transmission facilities shall be designed so as to: 1. Minimize visual impact; 2. Harmonize with or enhance the surroundings; 3. Not create a need for shoreline protection; 4. Utilize to the greatest extent possible natural screening. Williams Communications. Inc.

After crossing the river, the fiber optic line will be installed belowground along the western edge of the East Marginal Way South road prism and will be within the 200 -foot shoreline jurisdiction for approximately 1,600 feet across from the South Boeing Access Road. There will be no structures or accessory facilities located over the river There will be no overhead lines, and the fiber optic line will be installed in previously disturbed ROWs. As part of construction activities, a cleanup crew will perform final cleanup of the right - of -way, restoring pre - installation ground contours, installing erosion protection measures, restoring affected stream channels and removing fences and gates. Clean up will take place immediately after all work is completed. The seeding crews will apply seed and mulch where necessary. C. The construction and maintenance of utility facilities shall be done in such a way as to: 1. Maximize the preservation of natural beauty and the conservation of resources; 2. Minimize scarring of the landscape; 3. Minimize siltation and erosion; 4. Protect trees, shrubs, grasses, natural features and topsoil from drainage; 5. Avoid disruption of critical aquatic and wildlife stages. The riparian vegetation will be removed only beyond the riparian buffer if necessary and minimally, and vegetation will be restored to pre - project conditions if need be. Mitigation measures include: • Retain qualified biologists and resource specialists to monitor construction activities near specified sensitive biological areas; • Conduct a biological resource education program for construction crews and enforce construction restrictions before construction; • Avoid substantial impacts on non - listed special - status plant populations; • Confine construction equipment and associated activities to the project ROW in areas that support sensitive resources; • Avoid the dispersal of noxious weeds in the fiber optic line ROW; and • Establish and observe exclusion zones around riparian and wetland habitats that support special - status species. Construction monitors will be onsite during construction. They will locate and stake sensitive resources in the field, note the resources on the construction drawings, and advise the contractor regarding the necessary protection methods. They will also coordinate with monitors from the appropriate agencies. Monitoring activities associated with construction will proceed as follows: Williams Communications, Inc.

I— U The most basic way to avoid erosion is to minimize site disturbance. Williams' "' z contractors have been directed at the environmental training program to implement w co . practices that minimize site disturbance to ensure impacts are avoided or reduced to less - than- significant levels. These measures (described below) are routinely implemented in z the construction industry and have been proven successful for similar buried telecommunication system installations. The contractors will be directed to: • remove only the vegetation that is absolutely necessary to remove; E. • avoid off -road vehicle use; • avoid all sensitive resource areas; • avoid excessive trips along the right -of -way or access or maintenance roads; and, • instruct all personnel of the concepts of stormwater pollution prevention to ensure that all are conscious of how their actions affect the potential for erosion and sedimentation. Williams' inspectors will be onsite during all construction activities and will reinforce the importance of confining all vehicular traffic to the existing right -of -way and maintenance and access roads, as is practicable. Williams' contractors will be directed to perform initial site cleanup immediately following conduit and fiber optic line installation. Initial cleanup includes removing Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 7 City of Tukwila Revised Shoreline Application Addendum October 2000 ..,..w+mu -roan. debris and spoils and restoring original contours. Initial cleanup performed as part of the construction will contribute significantly to the overall site stability and will make final cleanup easier. The site will immediately begin to stabilize naturally with little additional disturbance during final cleanup. Proper compaction of subsurface soil serves as an erosion control measure. The reapplied topsoil in the ROW will be left in roughened condition to facilitate the establishment of vegetation and reduce the potential for erosion. E. Solid waste transfer stations shall not be permitted within the shorelines of the state. No solid waste transfer stations are associated with this fiber optic line project. No solid waste will be disposed along the river shoreline. Williams Communications, Inc.

Nonwater related development and residential development shall not be permitted waterward of the ordinal)) high water mark Within the City of Tukwila, the fiber optic line will be placed underground by the open trench method and will be attached to the East Marginal Way overpass. The conduit will be attached under the bridge in a reinforced fiberglass casing. After crossing the river, the fiber optic line will be installed below ground along the western edge of the East Marginal Way South road prism and will be within the 200 -foot shoreline jurisdiction for approximately 1,600 feet across from the South Boeing Access Road. There will be no structures or accessory facilities located over the river. B. Except in those cases when the height requirements of the underlying zones are more restrictive, no structure shall exceed a height of thirty -five feet above average grade level. This requirement may be modified if the view of a substantial number of residences will not be obstructed, if permitted by the applicable provisions of the underlying zoning, and if the proposed development is agricultural, water related or water dependent. The fiber optic line will be placed belowground in previously disturbed right -of -way (ROW) along the route. The line marker posts are the only visible aboveground features of the underground fiber optic line installation project. These will be placed approximately 500 feet apart to alert people of the presence of the line. The markers are typically 4 -feet tall, 3.5 -inch diameter round PVC posts with embossed lettering. In public ROWs, line marker discs will be used instead of line marker posts and will be applied to the curbs with epoxy. No structures are associated with the project in the City of Tukwila. C. All development shall be required to provide adequate surface water retention and sedimentation facilities during the construction period. Best Management Practices (BMPs) will be used to minimize the potential for sediment transport to surface waters during and following installation of the fiber optic line. A Stormwater Pollution Prevention Plan (SWPPP) has been prepared for the project, including detailed descriptions of typical BMPs, and when and how they are to be applied. A copy of the SWPPP will be submitted to the contractor prior to the start of construction. BMPs and erosion control measures for this project will be used to isolate active construction areas from surface waters, and to minimize the sediment concentration of surface runoff. Environmental monitors will coordinate with construction crews to ensure that all necessary BMPs are followed and erosion control measures are installed and functioning properly.

Best management practices detailed in the Stormwater Pollution Prevention Plan (SWPPP) will be implemented. Restrictions will be placed on all equipment refueling, servicing, and maintenance supplies and activities. All maintenance materials, oils, grease, lubricants, antifreeze, and similar materials will be stored offsite in staging areas. If these materials were required during field operations, they will be placed in a designated area away from site activities and sensitive resources. The equipment used for the proposed fiber optic line will need periodic maintenance and refueling. These activities will be accomplished responsibly, using the prescribed spill prevention countermeasures. No refueling or servicing will be done without absorbent material or drip pans underneath to contain spilled fuel. Any fluids drained from the machinery during servicing will be collected in leak -proof containers and taken to an appropriate disposal or recycling facility. If these activities result in damage to or accumulation of a product on the soil, it will be assessed and disposed of properly. Under no circumstances will knowingly contaminated soils be added to a spoils pile. Williams Communications, Inc. Fiber Optic Line Installation Project Portland Oregon to Seattle, Washington 2 City of Tukwila Shoreline Application Addendum August 23, 2000 During construction, all vehicles and equipment required onsite will be parked or stored at distances stipulated by the local jurisdictional ordinance so as not to affect rivers, streams, wetlands, known archeological sites, and other sensitive resource areas. These areas will be identified on the ground and noted on appropriate maps and construction drawings. All vehicle and equipment wash down activities will be conducted at the staging areas. G. The regulations of this chapter have been categorized in a number of sections; regardless of the categorizations of the various regulations, all development must comply with all applicable regulations. The project will comply with all relevant regulations, as determined by Minnie Dhaliwal, Associate Planner for the City of Tukwila. Further, all federal and state environmental regulations and policies have been addressed and environmental documents have been prepared for the appropriate agency reviews. H. Development proposed in shorelines of the states shall maintain setbacks, provide easements or otherwise develop the site to permit a trail to be constructed or public access to continue where: 1. There is a proposed trail in the King County trail system; or 2. Part of the site is presently being used and has historically been used for public access. The fiber optic line will be installed belowground and therefore will not interfere with any existing/proposed trails. The site is not presently used as public access to the Duwamish River. 1. Along shorelines of the state on Lake Sammamish, no building shall be placed on lands below thirty -two and one -half feet mean sea level. The project will not take place along shorelines of the state on Lake Sammamish. J. The regulations of this chapter are in addition to other adopted ordinances and rules. Where conflicts exist, that which provides more protection to sensitive areas shall apply; except that water dependent uses shall adhere to the applicable regulations and policies of the King County Shoreline Master Program. The project will comply with all relevant regulations, as determined by Minnie Dhaliwal, Associate Planner for the City of Tukwila. Williams Communications, Inc.

Utility facilities may be permitted in the urban environment subject to the general requirements section (Section 25.16.030) of this chapter, provided: A. Utility and transmission facilities shall: 1. Avoid disturbance of unique and fragile areas; 2. Avoid disturbance of wildlife spawning, nesting and rearing areas; 3. Overhead utility facilities shall not be permitted in public parks, monuments, scenic recreation or historic areas. Construction avoidance windows have been identified to minimize and avoid sensitive resources during critical times. Erosion and sediment controls will be used to ensure minimal disturbance to the river. Revegetation, where appropriate, will occur as soon as possible to minimize changes to these fish and wildlife species habitat as well as minimize corridor fragmentation. Wildlife species potentially present in the project ROW include: Bald Eagle, Osprey, Vaux's swift, Great blue heron, Cavity nesting ducks, Pileated woodpecker, Waterfowl, Townsend's big -eared bat, Western pond turtle, Oregon spotted frog, Western toad, and Valley silverspot. The following measures have been developed to avoid or minimize potential impacts to wildlife from implementation of the proposed project: Reptiles and amphibians At seasonal streams that support suitable habitat for non - federally listed special status amphibians and reptiles where drilling is infeasible, impacts will be avoided initially by determining the presence or absence of these species, followed by constructing barrier fencing, and relocating individual animals during construction. General wildlife Retain qualified biologists and resource specialists to monitor construction activities near specified sensitive biological areas. Fill or cover open trenches. Any open trenches will be filled with earth material or covered with plywood or other material to prevent entrapment of wildlife at the end of each workday. Both ends of any open trench will be sloped to form escape ramps before covering. If wildlife is found in the trench, they will be removed by a biological monitor before resumption of work in that trench segment. Williams will specify this requirement in the agreements with all construction contractors. Bald eagle • No construction activity will occur within 2,600 feet of an open nest or 1,300 feet of a screened nest between January 1 and August 15, unless individual consultation with a Washington Department of Fish & Wildlife (WDFW) biologist determines that the buffer can be reduced.

Clean up will take place immediately after all work is completed. The seeding crews will apply seed and mulch where necessary. C. The construction and maintenance of utility facilities shall be done in such a way as to: 1. Maximize the preservation of natural beauty and the conservation of resources; 2. Minimize scarring of the landscape; 3. Minimize siltation and erosion; 4. Protect trees, shrubs, grasses, natural features and topsoil from drainage; 5. Avoid disruption of critical aquatic and wildlife stages. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 5 City of Ttdnvila Shoreline Application Addendum August 23, 2000 The riparian vegetation will be removed only beyond the riparian buffer if necessary and minimally, and vegetation will be restored to pre - project conditions if need be. Mitigation measures include: • Retain qualified biologists and resource specialists to monitor construction activities near specified sensitive biological areas; • Conduct a biological resource education program for construction crews ~ w and enforce construction restrictions before construction; �� • Avoid substantial impacts on non - listed special- status plant populations; -I o • Confine construction equipment and associated activities to the project co ROW in areas that support sensitive resources; LIJ _ • Avoid the dispersal of noxious weeds in the fiber optic line ROW; and cn LL • Establish and observe exclusion zones around riparian and wetland w O habitats that support special- status species. u. Construction monitors will be onsite during construction. They will locate and stake = o sensitive resources in the field, note the resources on the construction drawings, and 1-1-1 advise the contractor regarding the necessary protection methods. They will also Z F.. zo coordinate with monitors from the appropriate agencies. z Monitoring activities associated with construction will proceed as follows: v N; • locate all sensitive resources, construction methods, and avoidance measures w or mitigation measures on the construction drawings; v • prepare traffic control plans, as necessary; L- Z • stake and flag resources as stipulated in the environmental documentation and v (,), from results of field surveys conducted for each project route; p • prepare the rights -of -way and install sedimentation control measures where needed; • install conduit, the fiber optic line, and associated facilities; ▪ restore the rights -of -way and install erosion control measures; • apply seed and mulch as specified in the SWPPP and reclamation plans; • monitor erosion control; and, • monitor success of mitigation. D. Rehabilitation of areas disturbed by the construction and /or maintenance of utility facilities shall: 1. Be accomplished as rapidly as possible to minimize soil erosion and to maintain plant and wildlife habitats; 2. Utilize plantings compatible with the native vegetation. Williams Co,ununications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 6 City of Tukwila Shoreline Application Addendum August 23, 2000 The most basic way to avoid erosion is to minimize site disturbance. Williams' contractors have been directed at the environmental training program to implement practices that minimize site disturbance to ensure impacts are avoided or reduced to less - than- significant levels. These measures (described below) are routinely implemented in the construction industry and have been proven successful for similar buried z telecommunication system installations. The contractors will be directed to: i f.. z • remove only the vegetation that is absolutely necessary to remove; g • avoid off -road vehicle use; -J 0 • avoid all sensitive resource areas; N co w J ILI = • avoid excessive trips along the right -of -way or access or maintenance roads; and, wo M • instruct all personnel of the concepts of stormwater pollution prevention to g n ensure that all are conscious of how their actions affect the potential for erosion and sedimentation. I (31 I-w Williams' inspectors will be onsite during all construction activities and will reinforce the z '; importance of confining all vehicular traffic to the existing right -of -way and maintenance z 0 l-. and access roads, as is practicable. W uj 0 D C) Williams' contractors will be directed to perform initial site cleanup immediately o following conduit and fiber optic line installation. Initial cleanup includes removing w debris and spoils and restoring original contours. Initial cleanup performed as part of the x v construction will contribute significantly to the overall site stability and will make final LL p cleanup easier. The site will immediately begin to stabilize naturally with little additional iii z disturbance during final cleanup. 1: 0 z Proper compaction of subsurface soil serves as an erosion control measure. The reapplied topsoil in the ROW will be left in roughened condition to facilitate the establishment of vegetation and reduce the potential for erosion. E. Solid waste transfer stations shall not be permitted within the shorelines of the state. No solid waste transfer stations are associated with this fiber optic line project. No solid waste will be disposed along the river shoreline. Williams Communications, Inc.

If you have any questions on the requested revision, Carol Lumb is the planner assigned to the file and can be reached at 206 - 431 -3661. 1. The permit application is missing maps that identify the portions of the project that fall within the shoreline and therefore are not a part of MI2000 -018. At a meeting with Department of Community Development and Department of Public Works staff on August 16, 2000 to discuss this project, it was agreed that this project would be reviewed under two separate miscellaneous permits. One permit would be for the portion of the project that falls within the shoreline area of the Duwamish River. The second permit would be for the remainder of the project. Miscellaneous permit 2000 -018, is for the non - shoreline portion of the project. 2. The application is also missing a landscape restoration plan. It was agreed at the meeting on August 16th that a restoration plan for any landscaped areas that were to be disturbed by the staging areas or borings would be submitted. cc: Minnie Dhaliwal, Associate Planner c: \caro I \general\2000- memos \mi2000- 018 -2.doc 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 z z 6 �w _J C.) 00. co o W J N L_ . w0 g-J >L a: • a' _ F--' 1— 0 Z I- U• 0 1- w w.

Notification may be by mail, e-mail, FAX, or phone and shall include the starting date, description of work, location, and the control number of this HPA. 3. Work shall be accomplished per plans and specifications entitled "Joint Aquatic Resource Permit Application" and all associated attachments prepared by Jones and Stokes, dated "March 10, 2000 ", and submitted to the Washington Department of Fish and Wildlife, except as modified by this Hydraulic Project Approval. These plans reflect design criteria per Chapter 220-110 WAC. These plans reflect mitigation procedures to significantly reduce or eliminate impacts to fish resources. A copy of these plans shall be available on site during construction for inspection by WDFW enforcement personnel. All workers on site should be knowledgeable and trained regarding any of the conduit installation and restoration techniques they may be responsible for. GENERAL 4. Whenever feasible. the conduit -cable shall be hung from existing bridges. Support structures for atrial conduit crossings shall be located and attached in a manner which prevents damage by future flooding events. 5. Conduit alignment shall be as nearly perpendicular to the stream as possible. 6. The conduit shall be installed at a minimum of 10 feet bcncath each stream bed to be bored beneath so that subsequent disturbance of the streambed, and loss of drilling lubricant, is avoided. This depth may only be reduced after verbal consultation with the appropriate AHB. Conduit shall be installed a minimum of six feet beneath stream npproved for the "trench or plow" methods, if approved. 7. !fat any time, ns a result of project activities, fish are observed in distress, a fish kill occurs, or water quality problems develop (including equipment leaks, spills, or drilling lubricant upwell or "frac- out "), operations shall cease "MWi sx >xcu d FISH eca WILDLIFE Hoc _ RA.ULIC PROJECT APPRO L RCW 75.20.100 or RCW 75.20.108 State of Washington Department of Fish and Wildlife Region 3 Ofriee 1701 South 2d° Avenue Yakima, Washington 98902 -5720 DATE OF ISSUE: July 20. 2000 LOG NUMBER: 00- E4822 -01 and the WDFW and Washington Department of Ecology shall be contacted.immediately.

Where the railroad or a highway right -of -way is located directly adjacent to a stream, the conduit shall be installed on the side of the rail or highway right -of -way opposite the stream, whenever possible. 9. If high stream flows enter the work area and result in erosion or siltation during any phase of the project, work shall cease until the water subsides. All stockpiles must be projected from flood waters to prevent additional sediment concentrations. 10. No instream blasting is permitted. 11. If wet or muddy conditions exist in or near a sensitive area, the use of low ground pressure tracked equipment, or a "Spyder" excavator is required as indicated on page D -9 of the JARPA application SPILL PREVENTION CONTROL AND COUNTERMEASURES 12. All spill prevention and countermeasures listed in on page D -6 of the JARPA application must be implemented. J. The Spill Prevention Control and Countermeasures shall include containment and treatment of any wastewater, drilling lubricant, petroleum spills, or deleterious or toxic substances which may result from accidents, maintenance, operation, bore pit excavation and de- watering, or in any phase of conduit installation. 14. Spill mitigation measures shall be consistent with the Stormwater Pollution Prevention Plan to achieve no loss of functions and values of fish and shellfish habitat. The plan shall be implemented during all storm events and at all times of the day and week including weekends, to ensure that eroded sediment and wastewater dots not enter state :waters. CLEARING AND GRUBBING 15. Existing natural vegetation within the designated buffers (see county or city critical areas ordinance ) of all wetlands and streams shall be protected to the extent possible. Clearing and grubbing within the ROW shall be held to an absolute minimum. Where larger trees do not exist, the conduit should be plowed without clearing and grubbing to avoid removal of shrubs and native grasses. Plowing thorough and over shrubs is preferred to prior clearing and grubbing. 16. The clearing of vegetation within the construction right -of -way and approach trench shall be minimized. Vegetation shall be pruned or cut only as absolutely necessary to install the cable and conduit. Only trccs directly within the pipeline trench corridor shall be cut or removed. Trees less than five inches DBH and within the designated stream buffer, must be salvaged. 2"ClC"'4'��'r@S'�1wa'"�er y t Y.;g1+s4" jE t igsailtivra ce FISE ail ifILDLIFB 11 -)RAULIC PROJECT APPRU /AL RCW 75.20.100 or RCW 75.20.108 State of Washington Department of Fish and Wildlife Region 3 Orrice 1701 South 24' Avenue Yakima, Washington 98902 -572" DATE OF ISSUE: July 20. 2000 LOG NUMBER: 00- E4822 -01 17. If vegetation lies directly within the right of way of the conduit, vegetation shall be removed in the following order of priority. (a) Vegetation shall first be pruned as necessary to provide clearance for conduit installation. (b) If pruning is insufficient to provide access woody vegetation may be cut. (c) The tree and associated root -wad may only be removed if it lies directly within the conduit trench. 18. An excavator shall salvage woody vegetation within the ROW within the designated buffer feet of all streams. The root wads of woody shrubs and trees less than five (5) inches diameter shall be removed using a back hoe or excavator and temporary stockpiled along the ROW. Soils shall be temporarily placed around the root wads prior to replanting to ensure viability of the salvaged vegetation. The vegetation shall be transplanted back into the ROW corridor after placement of the conduit. The vegetation shall be transplanted back into the disturbed area prior to heavy equipment leaving the site. 19. Vegetation from upland areas outside of the designated buffers may be transplanted into the riparian corridor as mitigation if plant densities within the buffers are less than desired. 20. Trees located directly within the trench corridor which must be removed, should be placed as downed woody debris as wildlife habitat, or shall be placed within local streams under the direction of the local Area Habitat Biologist. Trees to be used as habitat mitigation should not be de- limbed and the root wads should remain attached if possible. Excess large woody debris may also be stockpiled in coordination with the local Area Habitat Biologist for future stream restoration projects. Only small debris considered a potential fire hazard should be chipped. DIRECTIONAL DRILLING 21. When directional drilling , all pits shall be isolated from surface flow. 22. Bore pits, or drilling fluid collection and recovery pits shall be located outside of the stream buffer designated by each city or county within their "critical areas ordinance ", or be located at least 25 feet from the ordinary high water line of each side of the stream, whichever is greater. If wetlands and alcoves in continuity with the stream are present, bore pits shall be located outside the buffers designated by the local city or county with jurisdiction Approach trenches and bore pits shall be located in a manner that minimizes thc removal or disturbance of existing woody riparian vegetation. 23.

This method may only be used after consultation with the appropriate AHB. 25. The conduit shall be installed at sufficient depth (six feet or more) so that subsequent disturbance of the streambed is avoided. 26. A temporary culvert bypass is required when using the trench excavation method in flowing streams. The culvert shall be of sufficient size to contain all expected stream flows. A berm of clean, washed rock (washed drain rock, or a combination of ecology blocks and drain rock, are commonly used) shall be placed over, and around each end of the temporary culvert. An apron of plastic sheeting (at least 12 -15 feet long) shall be placed within the stream channel above and below the berms located at each end of the temporary culvert. The apron shall extend up and over the berms to minimize infiltration of water into the work area. 27. When using trench excavation, the trenches shall be isolated from the flowing stream. Excavating, placement, and covering shall occur in a single pass of the equipment. ..;. Trenches shall be backfilled with native material in the same order as it was excavated, and the streambed shall be returned to pre - project condition. The top 18 inches of the excavation shall be covered with clean, washed gravel as indicated in the following provision. 29. The trench shall be backfilled with clean, washed, rounded, uniformly- graded gravel ranging in size from one to four inches, and the streambed shall be returned to pre - project condition. If the material which was used to coffer the ends . of the temporary culvert meets this criteria, it may be used. After the trench is back - filled, wastewater shall be :pumped from within the coffered area until it "clears up" and all loose sediments and dirt are removed. The coffer shall not be breached or removed until the internal work area is clean. 30. The conduit approach trench shall be isolated from the stream until laying of the conduit across the stream occurs. Trench plugs shall be used as necessary to prevent water from within the approach trench from draining into state waters. TRENCH EXCAVATION IN DRY STREAMS The following provisions provide an alternative conduit installation technique for streams which are dry during the time of conduit installation. This method may only be used after consultation with the appropriate AHB. Dry streams may be fish bearing, or there nray be fish bearing waters downstream. Care and protection of the bed and banks of dry streams must be provided to the sank extent as flowing streams. 31. The conduit shall be installed at sufficient depth (six feet or more) so that subsequent disturbance of the streambed is avoided. 32. The banks of dry or seasonal streams shall not be cut or pulled back to provide n ford or causeway for equipment. The bed and banks of dry streams shall only be disturbed directly within the trench Tine. Dry streams with steep or vertical banks may be crossed or forded, provided clean fill such as clean rock, Togs, concrete blocks (or some similar +sa.sti — ee. ro.c arr+r«;.!+ssc,. n5a.a sxMfue..,xyl w± n; rr :!•.ra,w:rr«+T:::;!ar.''Fr:.JFrt ��,Y:N`,'na"9Y�1 HY ZA.ULIC PROJECT APPRO RCW 75.20.100 or RCW 75.20.108 State of Washington Department of Fish and Wildlife Region 3 Office 1701 South 24" Avenue Yakima,' Washington 98902 -5720 PATE OF ISSUE: July 20. 2000 LOG NUMBER: 00- E4822 -01 material) is temporarily used to fill the channel to prevent damage to the banks. All temporary fill shall be removed after completion of the conduit installation. 3. Spoils may be stockpiled within the dry streambed provided they are completely recovered and removed from the floodplain of the stream at completion of the conduit installation, and the bed is returned to pre - project condition. No loose spoils, earth fill, sediment, or silt shall remain within the streamed after conduit installation. 4. Trenches shall be backfilled with native material in the same order as it was excavated, and the streambed shall be returned to pre - project condition. The top 18 inches of the excavation shall be covered with clean, washed gravel as indicated in the following provision. 5. The trench shall be backfilled with clean, washed, rounded, uniformly - graded gravel ranging in size from one to four inches, and the streambed shall be returned to pre - project condition. If the native bed material meets this criteria, or if approved by the AHB, the native bedload may be used for backfill. 5. Heavy equipment shall cross dry streambeds at designated locations so as not to damage the streambed or associated riparian vegetation. VASTEWATER MANAGEMENT 7. Wastewater shall be contained and treated during all conduit installation activities to prevent the loss of sediments and deleterious materials into state waters. 8. The methods and Iocation of the wastewater treatment mechanism must be described in detail. Wastewater containment and treatment structures shall not be located so as to damage existing riparian vegetation. Installation and dismantling techniques for the treatment mechanisms must also be described. 9. Wastewater from bore pits or trenches, drilling slurry, lubricants, and sediments from project activities and de- watering, shall be routed to an upland area outside the ordinary high water line to allow removal of fine sediment and other contaminants prior to being discharged to state waters. It is suggested that all drilling lubricants be recycled, collected, and hauled from the site to prevent loss into state waters. In no instances shall wastewater be allowed to enter the natural watercourse or adjacent wetlands unless all sediments have been removed, and the discharge results in no visible turbidity. 3. Wastewater treatment mechanisms such as: settling ponds, swales, irrigation ditches, settling tanks, filter fences, sills, straw bales and other similar mcthods may be implemented. 1. Permanent spoil disposal sites for collected sediment or contaminants must be designated. ROSION CONTROL 1. 1 f unexpected rain or inclement weather occurs, and sediments, stockpiles, and wastewater are not adequately confined and pose a risk of contaminating state waters, work shall cease and the department shall be contacted. y ary nrifo-xrrxgx�xwr�s-• Silt Fences 43. If silt fences are used, they must be placed as close to the source of the sediment as is possible and shall be installed as described in Appendix F of the JARPA application and as described below. 44. All silt fences must be countersunk a minimum of one foot into the soil. Silt fences shall be maintained to prevent tearing, breaching, or blowouts. Silt fencing typically is placed near the stream or wetland intended to be protected thereby collecting the eroded fines in the least desirable location. At project conclusion, the accumulated sediments are often then released when the silt fences are removed. A heavy mulch of certified "weed free" straw, or similar ground cover, is much preferred to silt fences as it will prevent the initial mobilization of erodible fines. 45. Erosion control practices shall be applied in a manner which prevents the loss of sediments, mud, soils, fines, etc. from entering state waters. Erosion control shall primarily consist of mechanisms to prevent initial mobilization of sediment. Filter fences should be only considered secondary erosion control mechanisms. 46. Catch aprons must be used in conjunction with silt fence to ensure complete recovery of captured sediments and prevent the release of sediments into state waters. Catch aprons shall line the deposition, or backwater area, of all silt fences, sills, and straw bales used as temporary sediment traps. Spoil Placement 47. All excavated spoils shall be disposed of at an upland site in a manner that will prevent them from re- entering state waters. Excavated soils shall not be temporarily or permanently placed on or over existing woody riparian—vegetation outside the ROW. Temporary spoil piles must be located where they are completely recoverable and must not be placed, or allowed to waste into state waters. If de- watering is required, the sediment shall be disposed of in a location and manner that will prevent the run -off from entering state waters. -+8. Spoils must be placed in a manner and location where they are recoverable without causing additional environmental damage. This may necessitate the placement of a temporary barrier of fabric or plastic sheeting on the ground prior to spoil placement to ensure efficient recovery. 49. The applicant shall be responsible for stabilizing all slopes which are potentially unstable to ensure sediment does not reach state waters and fish habitat is protected. 50..A11 excess waste material, drilling slurry, construction debris, dirt, overburden, or spoils resulting from this project shall be deposited above the limits of flood water in an approved upland disposal site. The permanent disposal site shall be coordinated with the department prior to disposal. Soil Protection 5E Erosion control mechanisms shall be applied in a manner which prevents the loss of sediments into state waters during , and after, project implementation. All disturbed soils must be protected from erosion until such time that vegetation is adequately rc- established to the extent that erodible soils are fully protected from crosion. 52. If high stream flows enter thc work arca and result in erosion or siltation during any phase of the project, work shall cease until flows subside. 53. All disturbed slopes to thc strcam shall bc stabilized and rcvcgetated. Terracing, water bars, hay bales, "Gcowcb" and other erosion control structures shall bc used to stabilize disturbed slopes and prevent crosion into state waters. I f any slumping or wasting of sediment or deleterious material into the water occurs as a result of this project, the local AID shall be contacted and a site specific mitigation plan may he required.

A mulch of hay or straw, (certified free of noxious weeds) a minimum of four inches thick shall be placed over all exposed soils and spoil piles which could erode into a stream or adjacent wetland. 56. An erosion control mulch, or matting, shall be applied to all loose soils and spoil piles during all phases of construction to prevent sediments or sediment laden water from entering a natural watercourse or adjacent wetlands. Sediment Traps 57. All sediment traps and catchments shall include aprons on the bed of the settling areas or pond to provide opportunity to capture and remove the sediment. Traps without aprons typically result in the release of sediments when the structure is removed. At project conclusion, the aprons shall be "pursed up" and all accumulated sediments must be removed from slopes, ditches, swales or other areas where it could erode into state waters. Cyclone fencing material may be placed under the fabric aprons if necessary to provide additional structural integrity and prevent the fabric from ripping during removal of accumulated sediment. ;8. Silt collection aprons shall also be placed immediately upstream of any straw bales used to contain and collect sediments within ditches or rills leaving the work area. The aprons shall be placed under the ponded areas resulting from the straw bale structures. Equipment Restrictions 39. All equipment used in or around state waters shall be clean, in good repair, and inspected prior to use to ensure that no fluid leaks are present. This inspection shall take place at least daily while in use to ensure the equipment remains clean and in good repair. Should a leak occur, the equipment shall be immediately repaired or removed from the area. Fueling of equipment shall not take place within 150 feet of surface waters. ;0. The drive mechanisms (tracks or wheels) of equipment shall not enter the ordinary high water mark of any strcam during any phase of this project unless authorized by the local AHB. 4TITIGATION ;1. •1. In the event thatsediment, drilling fluid (frac- outs), wastewater, petroleum products, or any other deleterious substances are lost into state waters, or in the event that any vegetation is removed within designated buffers, or if adverse impacts to fish life or their habitat occurs, a mitigation plan shall be developed that includes steps to avoid, minimize, repair, and replace the ecological functions and values of the site. This includes mitigation for unavoidable impacts such as tree removal within designated stream buffers, despite application of the BMP's listed in Appendix D -1 of the JARPA application. Tree removal %vith designated buffers could be mitigated by placement of two similar sized trees removed from upland areas within the ordinary high water mark of the strcam. A plan to mitigate unavoidable impacts should bc completed prior to project initiation unless approved otherwise by the department. Large woody debris (LWD) which must bc removed from upland areas \vithin the conduit right -of -way may be placed within the stream to provide fish habitat mitigation, provided the placement is conducted with the coordination and prior approval of the local Arca Habitat Biologist. '3. Excess LWD removed from upland areas may also he stockpiled in an accessible location to provide material for future salmonid restoration projects. 4. Woody vegetation rcmovcd from within the ROW, and too large to transplant. shall bc scattered over the disturbed area in a manner so ns to provide wildlife habitat and provide erosion control. kafa+++.',vo.ci;,5,,, eke. 65. Large woody debris (LWD) which must be removed from the conduit right -of -way may be placed within the stream to provide fish habitat, provided the placement is conducted with the coordination and prior approval of the appropriate, local AHB. . The LWD shall be placed in the stream using full suspension in a manner which prevents damage to the bed or banks of the stream. The LWD may also be stockpiled in an accessible location to provide material for future salmonid restoration projects. VEGETATION RESTORATION 67. All disturbed soils within the designated stream buffersor adjacent wetlands shall be revegetated with native grasses, shrubs, and trees at the same density, or greater, as exists in adjacent undisturbed areas. All disturbed areas shall be protected from erosion during all stages of construction and until such time that vegetation is re- established. If care is exercised during the initial clearing of the conduit right -of -way, and woody vegetation is salvaged and replanted at the site, only seeding with native grasses may be required. 68. Revegetation shall reflect species and densities of adjacent undisturbed areas. Only plants indigenous to the site shall be planted. Revegetation shall occur prior to March 31, 2002, and shall conform to local vegetation patterns (eg. vertical vegetation change, (willows to alder, alders to conifer etc.) . 69. All woody vegetation less than five inches in stem diameter within the ROW of the project shall be salvaged and replanted at the site. Trees cut within the riparian area which are too large to transplant shall be placed within the stream, or disturbed upland area, under direction of the department or as indicated in a Mitigation Plan. 70. The site shall be monitored every three months for the first year and every six months for three years to ensure revegetation of the site. Dead, dying, or damaged plants shall be replaced during the next available planting window to ensure a minimum of 80 percent survival. Weed control shall be implemented as necessary to prevent establishment of noxious weeds or exotic plant species. 71. Only those areas physically incapable of being revegetated, or determined by the department to be incapable of supporting vegetation life, need not be planted. However, off -site or out -of -kind mitigation may be required. MONITORING AND MAINTENANCE PLAN 72.•It shall be the conduit owner's responsibility to maintain the conduit in a manner which prevents loss of fish life, Toss of fish habitat, impairments to fish passage, or loss of productivity due to toxic spills. 73. The WDFW shall be contacted prior to abandonment of existing conduits. The abandoned conduit shall be removed at WDFW' s discretion, and direction. In the event that an abandoned conduit is exposed, it shall be removed within the next available work window for the stream after consultation with the department. 74. All erosion and sediment control measures must be checked within 24 hours of each 0.5 inch or greater rainfall event (or every 12 hours during extended periods of rainfall) and every 14 calendar days between October 15th and April 15th, until such time that successful revegetation occurs. Between April 16th and October 14th, inspections shall be conducted every 30 days. 75. Ineffective erosion control measures must be repaired or replaced as soon as possible and no later than 24 hours. tTNEXPECTED CIRCUMSTANCES 6. In the event of a stream blowout (visible frac -out) during boring activity, leaks, ruptures, cracks, or noted vertical or lateral stream instability, the local Arca Habitat Biologist shall be contacted immediately, and provisions of the Spills and Materials Management Plan, listed on page D -6 of the JARPA application shall be invoked. • .•,+ S�"'?;w'xi,n:�.i)F�:�• °.rue,!; }.rfP.xY.�.:i 77.

These laws and the following design criteria are essential for the protection of fish at surface water diversions. Fish drawn into hydropower, irrigation, water supply, and other diversions are usually lost from z � the fish resources of the state of Washington. L'12 JU The following criteria are based on the philosophy of physically excluding fish from being entrained in water co o diverted without becoming impinged on the diversion screen. The approach velocity and screen mesh opening w = criteria are based upon the swimming stamina of emergent size p g g fry in low water temperature conditions. It is � „_ IA 0 recognized that there may be locations at which design for these conditions may not be warranted. Unless conclusive data from studies acceptable to Washington Depar Lucent of Fish and Wildlife indicate otherwise, it is assumed that these extreme conditions exist at some time of the year at all screen sites. co =d I... W Additional criteria may be required for unique situations, large facilities or intakes within marine waters. z = ro zr LXXVIlL Screen Location and Orientation o� A. Fish screens in rivers and streams shall be constructed within the flowing stream at the point of W ai diversion and parallel to the stream flow. The screen face shall be continuous with the adjacent bankline. A smooth transition between the screen and bankline shall be provided to prevent �- z eddies in front, upstream and downstream of the screen. w U= Where it can be thoroughly demonstrated that flow characteristics or site conditions make z construction or operation of fish screens at the diversion entrance impractical, the screens may be installed in the canal downstream of the diversion. B. Diversion intakes in lakes and reservoirs shall be located offshore in deep water to minimize the exposure of juvenile fish to the screen. Salmon and trout fry generally inhabit shallow water areas near shore. C. Screens constructed in canals and ditches shall be located as close as practical to the diversion. They shall be oriented so the angle between the face of the screen and the approaching flow is no more than 45°. All screens constructed downstream of the diversion shall be provided with an efficient bypass system. LXZX. Approach Velocity The approach velocity is defined as the component of the local water velocity vector perpendicular to the face of the screen. Juvenile fish must be able to swim at a speed equal or greater than the approach velocity for an extended length of time to avoid impingement on the screen. The following approach velocity criteria are maximum velocities that shall not be exceeded anywhere on the fact of the screen. A maximum approach velocity of 0.4 feet per second is allowed. • rf+V'•x .� q2^C:,.. _'. •-H�'t�L4"ii'��or !f•t(• 7far#�: :a' „At The approach velocity is calculated based on the gross screen area not the net open area of the screer mesh. The intake structure and /or fish screen shall be designed to assure that the diverted flow is uniformly distributed through the screen so the maximum approach velocity is not exceeded. LXXX. Minimum Screen Area The minimum required screen area is determined by dividing the maximum diverted flow by the maximum allowable approach velocity. To find the screen area in square feet, divide the diverted flow in cubic feet per second (450 gpm = 1.0 cubic foot per second) by the approach velocity 0.4 feet per second): Minimum ScreenArea - Diverted Flow (cub icfeet /second) Approach Velocity (feet per second) The minimum required screen area must be submerged during lowest stream flows and may not include any area that is blocked by screen guides or structural members. Diversions less than or equal to 180 gallons /minute (0.4 cfs) require a minimum submerged screen area of 1.0 square foot, which is the smallest practical screening device. LD'XXI. Sweeping Velocity The sweeping velocity is defined as the component of the water velocity vector parallel to and immediately upstream of the screen surface. The sweeping velocity shall equal or exceed the maximum allowable approach velocity. The sweeping velocity requirement is satisfied by a combination of proper orientation (angle of screen 45° to the approaching flow) of the screen relative to the approaching flow and adequate bypass flow. Screen bay piers or walls adjacent to the screen face shall be flush with screen surfaces so the sweeping velocity is not impeded. L=" Screen Mesh Size, Shape, and Type of Material Screen openings may be round, square, rectangular, or any combination thereof, provided structural integrity and cleaning operations are not impaired. Page 14 of 16 Screen mesh criteria is based on the assumption that steelhead and /or resident trout fry are ubiquitous in the state of Washington and will be present at all diversion sites. Following are the maximum screen openings allowable for emergent salmonid fry. The maximum opening applies to the entire screen structure including the screen mesh, guides, and seals. The profile bar criteria is applied to the narrow dimension of rectangular slots or mesh. o `eri . ire Mesh. W v 'VY ::.Pr.ofile Baz erforated Plate ' '. 0.087 inch (6 -14 mesh) 1.75 mm (0.069 inch) 0.094 inch (3/32 inch) The, allowable woven wire mesh openings is the greatest open space distance between mesh wires. An example allowable mesh specifications is provided; there are other standard allowable openings available. The mesh specification gives the number of mesh openings per lineal inch followed by the gauge of the wires. For example, 6 -14 mesh has six mesh openings per inch of screen. It is constructed with 6, 14 -gauge (0.080 inch diameter) wires per inch. The profile bar openings are the maximum allowable space between bars. The allowable perforated plate openings are the diameter of circular perforations. Perforated slots are treated as profile bars. Screens may be constructed of any durable material; woven, welded, or perforated. The screen material must be resistant to corrosion and ultraviolet damage. For longevity and durability, minimum wire diameter for woven mesh shall be 0.060 inch (18 gauge) on fixed panel screens, where they are not subjected to impact of debris. Minimum wire diameter for woven mesh shall be 0.080 inch (14 gauge) for rotary drum screens, traveling belt screens, and in areas where there is a potential for damage from floating debris or cleaning operations. VI. Bypass All screens constructed downstream of the diversion shall be provided with an efficient bypass system to rapidly collect juvenile fish and safely transport them back to the river. The downstream end of the screen shall terminate at the entrance to the bypass system. It is the water diversion owner's responsibility to obtain necessary water rights to operate the fish bypass; failure to do so may be considered failure to meet state screening law requirements. Page 15 of 1 G Fish screens shall be cleaned as frequently as necessary to prevent obstruction of flow and violation of the approach velocity criterion. Automatic cleaning devices will be required on large.screen facilities. Additional detailed information is available explaining the background and justification of these criteria and showing standard details of flow distributors, acceptable bypass designs, and screen areas required for various flows.

Utility Line Activities. Activities required for the construction, maintenance, and repair of utility lines and associated facilities in waters of the United States as follows: (1) Utility lines: The construction, maintenance, or repair of utility lines, including outfall and intake structures and the associated excavation, backfill, or bedding for the utility lines, in all waters of the United States, provided there is no change in preconstruction contours. A "utility line" is defined as any pipe or pipeline for the transportation of any gaseous, liquid, liquefiable, or slurry substance, for any purpose, and any cable, line, or wire for the transmission for any: purpose of electrical energy, telephone, and telegraph messages, and radio and television communication (see Note 1, below). Material resulting from trench excavation may be temporarily sidecast (up to three months) into waters of the United States, provided the material is not placed in such a manner that it is dispersed by currents or other forces. The District Engineer may extend the period of temporary side casting not to exceed a total of 180 days, where appropriate. In wetlands, the top 6" to 12" of the trench should normally be backfilled with topsoil from the trench. Furthermore, the trench cannot be constructed in such a manner as to drain waters of the United States (e.g., backfilling with extensive gravel layers, creating a french drain effect). For example, utility line trenches can be backfilled with clay blocks to ensure that the trench does riot drain the waters of the United States through which the utility line is installed. Any exposed slopes and stream banks must be stabilized immediately upon completion of the utility line crossing of each waterbody. (ii) Utility line substations: The construction, maintenance, or expansion of a substation facility associated with a power line or utility line in non - tidal waters of the United States, excluding non -tidal wetlands adjacent to tidal waters, provided the activity does not result in the loss of greater than 1/2 acre of non -tidal waters of the United States. (iii) Foundations for overhead utility line towers, poles, and anchors: The construction or maintenance of foundations for overhead utility line towers, poles, and anchors in all waters of the United States, provided the foundations are the minimum size necessary and separate footings for each tower leg (rather than a larger single pad) are used where feasible. (iv) Access roads: The construction of access roads for the construction and maintenance of utility lines, including overhead power lines and utility line substations, in non -tidal waters of the United States, excluding non -tidal wetlands adjacent to tidal waters, provided the discharge does not cause the Toss of greater than 1/2 acre of non -tidal 1 E. KJ NATIONWIDE PERM CORPS SEATTLE DISTRICT /7 JL,gE 2000 waters of the United States. Access roads shall be the minimum width necessary (see Note 2, below). Access roads must be constructed so that the length of the road minimizes the adverse effects on waters of the United States and as near as possible to preconstruction contours and elevations (e.g., at grade corduroy roads or geotextile /gravel roads). Access roads constructed above preconstruction contours and elevations in waters of the United States must be properly bridged or culverted to maintain surface flows. The term "utility line" does not include activities which drain a water of the United States, such as drainage tile or french drains; however, it does apply to pipes conveying drainage from another area. For the purposes of this NWP, the loss of waters of the United States includes the filled area plus waters of the United States that are adversely affected by flooding, excavation, or drainage as a result of the project. Activities authorized by paragraphs (i) through (iv) may not exceed a total of acre Toss of waters of the United States. Waters of the United States temporarily affected by filling, flooding, excavation, or drainage, where the project area is restored to preconstruction contours and elevations, are not included in the calculation of permanent Toss of waters of the United States. This includes temporary construction mats (e.g., timber, steel, geotextile) used during construction and removed upon completion of the work. Where certain functions and values of waters of the United States are permanently adversely affected, such as the conversion of a forested wetland to a herbaceous wetland in the permanently maintained utility line right -of -way, mitigation will be required to reduce the adverse effects of the project to the minimal level. Mechanized Iandclearing necessary for the construction, maintenance, or repair of utility lines and the construction, maintenance, and expansion of utility line substations, foundations for overhead utility lines, and access roads is authorized, provided the cleared area is kept to the minimum necessary and preconstruction contours are maintained as near a's possible. The area of waters of the United States that is filled, excavated, or flooded must be limited to the minimum necessary to construct the utility line, substations, foundations, and access roads. Excess material must be removed to upland areas immediately upon completion of construction. This NWP may authorize utility lines in or affecting navigable waters of the United States, even if there is no associated discharge of dredged or fill material (See 33 CFR Part 322). Notification: The permittee must notify the District Engineer in accordance with General Condition 13, if any of the following criteria are met: (a) Mechanized land clearing in a forested wetland for the utility line right- of-wa y; 2 NATIONWIDE PERMIT /CORPS SEATTLE DISTRICT /7 JUNE 2000 (b) A Section 10 permit is required; (c) The utility line in waters of the United States, excluding overhead lines, exceeds 500 feet; (d) The utility line is placed within a jurisdictional area (i.e., a water of the i �.. ■ United States), and it runs parallel to a stream bed that is within that 4E- z jurisdictional area; CC 2 JU (e) Discharges associated with the construction of utility line substations u) o. that result in the loss of greater than 1/10 acre of waters of the United w i States; cn u.

Access roads used solely for construction of the utility line must be removed upon completion of the work and the area restored to preconstruction contours, elevations, and wetland conditions. Temporary access roads for construction may be authorized by NWP 33. NOTE 3: Where the proposed utility line is constructed or installed in navigable waters of the United States (i.e., Section 10 waters), copies of the PCN and NWP verification will be sent by the Corps to the National Oceanic and Atmospheric Administration, National Ocean Service, for charting the utility line to protect navigation. 3 NATIONWIDE PERMI I- /CORPS SEATTLE DISTRICT /7 JUNE 2000 Notification Requirement — Yes.

A letter containing the requisite information may also be used. w (d) District Engineer's Decision: In reviewing the PCN for the proposed activity, the District Engineer will determine whether the activity authorized by - o the NWP will result in more than minimal individual or cumulative adverse co environmental effects or may be contrary to the public interest. The w prospective permittee may, optionally, submit a proposed mitigation plan with cn o the PCN to expedite the process and the District Engineer will consider any w proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. If the District Engineer = a determines that the activity complies with the terms and conditions of the ~ z �. NWP and that the adverse effects on the aquatic environment are minimal, o the District Engineer will notify the permittee and include any conditions the w ~ District Engineer deems necessary. > U� Any compensatory mitigation proposal must be approved by the District 0 F- Engineer prior to commencing work. If the prospective permittee is required = 0 to submit a compensatory mitigation proposal with the PCN, the proposal may o be either conceptual or detailed. if the prospective permittee elects to submit z a compensatory mitigation plan with the PCN, the District Engineer•will o expeditiously review the proposed compensatory mitigation plan. The District o 1 Engineer must review the plan within 45 days of receiving a complete PCN Z and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment (after consideration of the compensatory mitigation proposal) are determined by the District Engineer to be minimal, the District Engineer will provide a timely written response to the applicant stating that the project can proceed under the terms and conditions of the nationwide permit. If the District Engineer determines that the adverse effects of the proposed work are more than minimal, then he will notify the applicant either: (1) That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; (2) that the project is authorized under the NWP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level; or . .rer i A,. r it• /' i r i h^7k }S'sl z rna'a1:. , ^r7? , rt. r ! �n cS?L`K7FrF t44/ ?SYIJ 1 Nationwide Permits / Seattle District / 7 June 2000 (3) that the project is authorized under the NWP with specific modifications or conditions. Where the District Engineer determines that mitigation is required in order to ensure no more than minimal adverse effects on the aquatic environment, the activity will be authorized within the 45 -day PCN period, including the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included, or a mitigation plan is required under item (2) above, no work in waters of the United States will occur until the District Engineer has approved a specific mitigation plan. • (e) Agency Coordination: The District Engineer will consider any comments from Federal and State agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for • mitigation to reduce the project's adverse effects on the aquatic environment to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than '/2 acre of waters of the United States, the District Engineer will, upon receipt of a notification, provide immediately (e.g., via facsimile transmission, overnight mail, or other expeditious manner), a copy to the appropriate offices of the Fish and Wildlife Service, State natural resource or water quality agency, EPA, State Historic Preservation Officer (SHPO), and, if appropriate, the National Marine Fisheries Service. With the exception of NWP 37, these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive, site - specific comments. If so contacted by an agency, the District Engineer will wait an additional 15 calendar days before making a decision on the notification. The District Engineer will fully consider agency comments received within the specified time frame, but will provide no response to the resource agency, except as provided below. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies' concerns were considered. As required by Section 305(b)(4)(B) of the Magnuson - Stevens Fishery Conservation and Management Act, the District Engineer will provide a response to National Marine Fisheries Service within 30 days of receipt of any Essential Fish Habitat conservation recommendations.

Use of Multiple Nationwide Permits. The use of more than one NWP for a single �. and complete project is prohibited, except when the acreage loss of waters of the z United States authorized by the NWPs does not exceed the acreage limit of the o NWP with the highest specified acreage limit. For example, if a road crossing over o tidal waters is constructed under NWP 14, with associated bank stabilization z authorized by NWP 13, the maximum acreage loss of waters of the United States for the total project cannot exceed 1/3 acre. 16. Water Supply Intakes. No activity, including structures and work in navigable waters of the United States or discharges of dredged or fill material, may occur in the proximity of a public water supply intake except where the activity is for repair of the public water supply intake structures or adjacent bank stabilization. 17. Shellfish Beds. No activity, including structures and work in navigable waters of the United States or discharges of dredged or fill material, may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. 18. Suitable Material. No activity, including structures and work in navigable waters of the United States or discharges of dredged or fill material, may consist of unsuitable material (e.g., trash, debris, car bodies, asphalt, etc.) and material used for construction or discharged must be free from toxic pollutants in toxic amounts (see Section 307 of the Clean Water Act). ilOak Nationwide Permits / Seattle District / 7 June 2000 19. Mitigation. The project must be designed and constructed to avoid and minimize adverse effects to waters of the United States to the maximum extent practicable at the project site (i.e., on site). Mitigation will be required when necessary to ensure that the adverse effects to the aquatic environment are minimal. The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a) Compensatory mitigation at a minimum 1:1 ratio will be required for all wetland impacts requiring a PCN. Consistent with National policy, the District Engineer will establish a preference for restoration of wetlands to meet the minimum compensatory mitigation ratio, with preservation used only in exceptional circumstances. (b) To be practicable, the mitigation must be available and capable of being done considering costs, existing technology, and logistics in light of the overall • project purposes. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferably in the same watershed; (c) The District Engineer will require restoration, creation, enhancement, or preservation of other aquatic resources in order to offset the authorized impacts to the extent necessary to ensure that the adverse effects on the aquatic environment are minimal. An important element of any compensatory mitigation plan for projects in or near streams or other open waters is the establishment and maintenance, to the maximum extent practicable, of vegetated buffers next to open waters on the project site. The vegetated buffer should consist of native species. The District Engineer will determine the appropriate width of the vegetated buffer and in which cases it will be required. Normally, the vegetated buffer will be 25 to 50 feet wide on each side of the stream, but the District Engineer may require wider vegetated buffers to address documented water quality concerns. If there are open waters on the project site and the District Engineer requires compensatory mitigation for wetland impacts to ensure that the net adverse effects on the aquatic environment are minimal, any vegetated buffer will comprise no more than 1/3 of the remaining compensatory mitigation acreage after the permanently filled wetlands have been replaced on a one -to -one acreage basis. In addition, compensatory mitigation must address adverse effects on wetland functions and values and cannot be used to offset the acreage of wetland losses that would occur in order to meet the acreage limits of some of the NWPs (e.g., for NWP 39, 'A acre of wetlands cannot be created to change a 1/2 ecre loss of wetlands to a 1/4 acre loss; however, Y2 acre of created wetlands can be used to reduce the impacts of a 1/3 acre loss of wetlands).

L' o .. w z F. o _ z Nationwide Permits / Seattle District / 7 June 2000 the prospective permittee is required to submit a compensatory mitigation proposal with the PCN, the proposal may be either conceptual or detailed. (d) To the extent appropriate, permittees should consider mitigation banking and other appropriate forms of compensatory mitigation. If the District Engineer determines that compensatory mitigation is necessary to offset losses of waters of the United States and ensure that the net adverse effects of the authorized work on the aquatic environment are minimal, consolidated mitigation approaches, such as mitigation banks, will be the preferred method of providing compensatory mitigation, unless the District Engineer determines that activity - specific compensatory mitigation is more appropriate, based on which is best for the aquatic environment. These types of mitigation are preferred because they involve larger blocks of protected aquatic environment, are more likely to meet the mitigation goals, and are more easily checked for compliance. If a mitigation bank or other consolidated mitigation approach is not available in the watershed, the District Engineer will consider other appropriate forms of compensatory mitigation to offset the losses of waters of the United States to ensure that the net adverse effects of the authorized work on the aquatic environment are minimal. 20. Spawning Areas. Activities, including structures and work in navigable waters of the United States or discharges of dredged or fill material, in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g., excavate, fill, or smother downstream by substantial turbidity) of an important spawning area are not authorized. 21. Management of Water Flows. To the maximum extent practicable, the activity must be designed to maintain preconstruction downstream flow conditions (e.g., location, capacity, and flow rates). Furthermore, the activity must not permanently restrict or impede the passage of normal or expected high flows (unless the primary purpose of the fill is to impound waters) and the structure or discharge of dredged or fill material must withstand expected high flows. The activity must, to the maximum extent practicable, provide for retaining excess flows from the site, provide for maintaining surface flow rates from the site similar to preconstruction conditions, and must not increase water flows from the project site, relocate water, or redirect water flow beyond preconstruction conditions. In addition, the activity must, to the maximum extent practicable, reduce adverse effects such as flooding or erosion downstream and upstream of the project site, unless the activity is part of a larger system designed to manage water flows. 22. Adverse Effects From Impoundments. If the activity, including structures and work in navigable waters of the United States or discharge of dredged or fill material, creates an impoundment of water, adverse effects on the aquatic system caused by the accelerated passage of water and /or the restriction of its flow shall be minimized to the maximum extent practicable. �•..ww ....rtww.wn.+M•... .-...»......,..._..... .......v+ww.•..ci..um...srwr..e n7 .�en,�M'�xa;..awa....vww. wx� •!- e�s2.i+w�^�;+%r+,:,v�< -'.lv. �rSri�vux�r._�rzn���+ a s' �.

Give brief, complete description of your proposal, including the proposed uses and the w o w size of the project and site. v o Williams Communications proposes to install approximately 176 miles of fiber optic line from o F— Portland, Oregon to Seattle, Washington. The fiber optic line installation is being proposed to w w meet the growing demand for network capacity in the Pacific Northwest and to connect existing �. points of presence (POP sites) in Portland and Seattle. Installation of the line will expand the u' O Pacific Northwest's national telecommunications access and enhance the capability and Cu �. reliability of the region's telecommunications infrastructure. i_ 0 z The proposed fiber optic line will be installed largely in the existing Williams pipeline (formerly Northwest Pipeline Corporation) natural gas pipeline right -of -way (ROW) easement between Portland and Seattle (hereafter called "the Pipeline Lateral "). Lateral ROWs to link the existing pipeline ROW to the Portland and Seattle POP sites will mainly follow existing city streets and highways (hereafter called the "Portland Lateral" and the "Seattle Lateral ", respectively). In brief, the ROW generally will: • Start at the Portland POP site located at 707 SW Washington Street; • Follow Portland city streets and cross the Willamette River at the Fremont Bridge; • Cross the Columbia River from the Port of Vancouver to Kelly Point Park in Portland; • Follow Lower River Road then Highway 501 out of the Vancouver area; • Follow NE 10th Avenue from south of NE 219th Street; • Enter the existing Williams gas pipeline ROW; • Generally follow the Williams Pipeline ROW to the City of Puyallup; • Exit the Williams Pipeline ROW and follow a combination of city streets, including Military Road, to the City of Seattle; • Take Fourth Ave into downtown Seattle; Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 4 SEPA Checklist March 2000 • Enter the Seattle POP site located at 1501 Fifth Avenue. The proposed ROW crosses numerous jurisdictions and will require approvals and permits from various federal, state, and local agencies. The only jurisdiction in Oregon is Portland. The Washington municipal jurisdictions are the cities of Vancouver, Castle Rock, Puyallup, Edgewood, Federal Way, Kent, SeaTac, Tukwila, and Seattle. The counties are Clark, Cowlitz, Lewis, Thurston, Pierce, and King. The Washington Department of Ecology is the lead agency for the State Environmental Policy Act (SEPA) process. 16 JU 00 The fiber optic line system consists of both aboveground and belowground components. The g o belowground facilities include the fiber optic line and conduit, manholes/handholes, and access i vaults. The aboveground facilities include the optical amplification (OP -AMP) stations and the cn u, fiber optic line marker posts. The fiber optic line, which is made up of bundled glass optical fibers wrapped in thin plastic u sheathing, is inserted into the flexible, high - density polyethylene (HDPE) conduits. The = e1 conduits have an outside diameter of 1.25 to 1.5 inches. The Portland and Seattle Laterals will consist of 6 to 20 conduits, while the Pipeline Lateral will have 6 to 9 conduits. Each conduit z '— will accommodate one fiber optic line, which measures approximately 0.85 inch in diameter and I-- O is composed of 96 to 288 hair -thin glass fibers. ? o U General construction methods will include plowing or trenching installations within the existing o !' pipeline ROW, except at flowing streams and other sensitive resources (e.g., wetlands and = v cultural sites). Plowing installation involves using a tracked vehicle (e.g., a Caterpillar, 1-- approximately 8 feet in width) with a conduit reel on front and a plow blade on back. As the Cat LL- O moves, conduit is fed to the back side of the plow blade. The blade laterally separates the soil to v cn 48 inches deep and lays the conduit as the plow advances. Once the plow disturbs the ground, P the soil settles naturally over the conduit. The soil is then compressed evenly with the surrounding ground surface. The width of direct disturbance by the plow is typically 12 inches. Trenched installations typically involve a rubber -tired backhoe, or an excavator, digging a trench 4 to 6 feet wide, 8 to 10 feet long, and 48 inches deep (factors such as locations of existing buried utilities, geographical and topographical constraints, and environmentally sensitive areas can affect the trench dimensions). Methods used to avoid and minimize impacts to sensitive resources include directional drilling under the resource or, in some cases, attaching the conduit and fiber line to existing bridges. Directional drilling will be used for the larger sensitive resources. Three OP -AMP stations will be located approximately every 44 miles along the ROW to boost the optical signal. The stations will be placed near, but not within, the ROW easement on 2.5- to 5 -acre, fenced sites in Cowlitz, Lewis, and Pierce Counties. Station sites will be selected to avoid sensitive resources. The OP -AMP stations will consist of precast concrete buildings placed on concrete pads. The concrete pads, including concrete stoops, for all potential OP- AMP modules will cover approximately 3,850 square feet. Each OP -AMP station will have a maximum total height of approximately 11 feet. Each building is shipped from the manufacturer equipped with one or two heating, ventilation, and air conditioning units to maintain a steady Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 5 SEPA Checklist March 2000 temperature for the electronic equipment housed inside the station. The unstaffed, locked facility will require commercial electric power and telephone service. Periodic maintenance will occur to assure that the facility is operating properly. A diesel generator and a diesel storage tank will be installed for emergency back -up power. The Cowlitz County and Lewis County OP -AMP station sites have no zoning designations. The Pierce County OP -AMP station site is zoned EC, Employment Center. All three sites are undeveloped lots, and there have been no structures on these sites previously. Construction ROWs are typically 20 to 30 feet wide in upland areas. The ROW will be narrowed as appropriate to minimize disturbance in sensitive areas (e.g., streams and wetlands). Site access will be obtained through the use of existing access roads to the extent possible. Most of the fiber optic line will be placed in existing ROW with access roads. However, if needed, new access roads will be identified as construction plans are developed and finalized. Staging areas typically will be established along the proposed ROW during project construction. Staging areas will be sited in areas that have been previously disturbed (e.g., paved or compacted dirt and gravel) or by renting commercial storage yards along the ROW. Wetlands and streams were categorized and catalogued as part of field surveys for federal, state, and local permitting processes. The proposed ROW crosses the following named rivers as identified on U.S. Geological Survey (USGS) quadrangle maps: the Willamette, Columbia, Lake, Lewis, Kalama, Coweeman, Toutle, Cowlitz, Skookumchuck, Deschutes, Nisqually, Puyallup, and Duwamish. The fiber optic line will be installed across these rivers by drilling underneath the river or attaching the line to an existing bridge. Numerous named and unnamed creeks also occur along the ROW. See Appendix A for a detailed project description, which includes information about the ROW, facilities, construction management and techniques, operations, and mitigation and safety measures. 12. Location of proposal, and directions to the site. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal will occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. Within the Portland Lateral, the ROW begins in Vancouver, Washington after crossing the Columbia River. The ROW leaves Vancouver, follows Highway 501 and other surface streets or dike roads on the western edge of Lake Vancouver, and finally connects to the existing Williams natural gas pipeline ROW at the Lake River in Clark County. The route follows the Pipeline Lateral to Highway 502, then travels north on Highway 502 for approximately 10 miles before re- connecting with the Williams Pipeline Lateral. The fiber optic line route then follows the Williams Pipeline ROW for approximately 110 miles through Clark, Cowlitz, Lewis, and Williams Communications, Inc.

Within Pierce County, the route utilizes the gas pipeline ROW and local road ROWs until it exits the gas pipeline ROW on Wildwood Drive in Puyallup. The Seattle Lateral utilizes local roads to connect Puyallup to downtown Seattle. Appendix A provides a detailed summary of the route description. The three OP -AMP stations will be located on existing disturbed sites at the following locations: • Within Cowlitz County, the OP -AMP station site is located in Township 6 North, Range 1 West, northeast quarter Section 4, northeast of and directly adjacent to the Williams Pipeline. • Within Lewis County, the OP -AMP station site is located south of Centralia -Alpha Road in Township 14 North, Range 2 West, in the northeast corner of Section 36, approximately 300 feet east of the Williams Pipeline ROW. • Within Pierce County, the OP -AMP station site is located west of Canyon Road East in Township 19 North, Range 4 East, in the southeast corner of Section 36, immediately north of and adjacent to the Williams Pipeline ROW. A map showing the entire route of the fiber optic line from Portland to Seattle and the location of the three OP -AMP station sites is given in Appendix A. B. ENVIRONMENTAL IMPACTS 1. EARTH a. General description of the site (circle one): flat, rolling, hilly, steep slopes, mountainous; other: The project passes through a variety of topographic areas ranging from relatively flat ground within the major river valleys to hilly, rolling topography and side -slope traverses through much of the southwest Washington portion of the line. North of the Nisqually River the topography is rolling. In some locations, primarily where the line descends into or rises from river and stream valleys, there are steep slopes. One OP -AMP station is located in each of the following counties: Cowlitz, Lewis, and Pierce. The site for the proposed OP -AMP station in Cowlitz County is 5.0 acres of hummocky slope. The site for the proposed OP -AMP station in Lewis County is 5.0 acres that are terraced. The site for the proposed OP -AMP station in Pierce County is 2.24 acres of flat upland. A detailed Geology Report has been prepared and is available for review upon request. b. What is the steepest slope on the site (approximate percent slope)? Along portions of the line within the existing Williams Pipeline ROW in southwest Washington there are several locations where slopes exceed 40 %. The steepest slopes crossed by the fiber optic line are adjacent to river and stream valleys. The steeper slopes are typically located south of the Nisqually River, with the slopes north of the Nisqually River typically gentler. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 7 SEPA Checklist March 2000 The steepest slope for the proposed OP -AMP station in Cowlitz County is 15 to 25 %. The steepest slope for the proposed OP -AMP station in Lewis County is 0 to 5% in upland areas and 15 to 25% on the terrace slope. The steepest slope for the proposed OP -AMP station in Pierce County is 0 to 5 %. c. What general types of soils are found on the site (for example; clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The fiber optic line will encounter a wide range of soil types throughout its 160 -mile length in Washington. These soil types will include soft/loose alluvial soils in the major river valleys; stiff to hard/compact to dense, residual soils and older, weathered glacial soils in the upland portions in southwest Washington; and compact to dense glacial soils in the upland regions from the Deschutes River northward. Peat and other soft compressible soils may be encountered in the major river valleys and in the Lacamas Creek valley north of the Nisqually River. The fiber optic line does not cross any prime farmland. The soil for the proposed OP -AMP station in Cowlitz County is loamy silt. The soil for the proposed OP -AMP station in Lewis County is sandy loam. The soil for the proposed OP -AMP station in Pierce County is gravel to sandy gravel. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. The fiber optic line crosses or closely approaches 15 active landslides and 24 potentially active landslides. A landslide is considered active if it has shown evidence of movement in the past 50 years. A potential landslide has shown evidence of movement in the past 10,000 years. There are no surface indications or history of unstable soils in the immediate vicinity of the proposed OP -AMP stations in Cowlitz, Lewis, and Pierce Counties. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Filling and grading activities will be conducted primarily at the OP -AMP station sites. Minimal grading and filling may be required at selected locations with steep slopes along the ROW. Minimal grading and filling will be required to level the flatter, southeast portion of the OP -AMP station site in Cowlitz County. Minimal grading will be required for the OP -AMP station site in Lewis County, and minimal grading and filling will be required to level the flatter, northeastern portion of the OP -AMP station site in Pierce County. Fill material will likely come from onsite sources. Filling or grading will be limited to creating a level building pad and parking area, along with the excavation and re- burial of the fiber optic line. Native soils will be used to backfill the fiber optic line trench, and will be used as fill across the site where possible. Williams Communications, Inc.

Could erosion occur as a result of clearing, construction or use? If so, generally describe. There is the potential for erosion as a result of construction and operation of the fiber optic line. However, if good construction practices and standard industry Best Management Practices (BMPs) (see Appendix B) are employed, there should be minimal impacts from erosion during construction and operation of the fiber optic line. Similarly, implementation of good construction practices and BMPs will minimize erosional impacts on the proposed OP -AMP station sites in Cowlitz, Lewis, and Pierce Counties. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings). Installation of the fiber optic line will be by plowing, trenching, or drilling. Manholes and handholes covering a minimal amount of impervious surface will be placed approximately every 3 to 5 miles. The Cowlitz and Lewis County OP -AMP station sites occupy approximately 5.0 acres each. The Pierce County OP -AMP station site occupies 2.5 acres. An area of approximately 150 by 100 feet will be fenced, cleared, and covered with gravel on each site. The OP -AMP stations will occupy approximately 3,850 square feet and the backup diesel generator will occupy a 200 - square foot area. This 4,050- square foot area will be constructed on a concrete foundation. Most of the remainder of the fenced site will be covered with gravel. Therefore, the total impervious surface area for the Cowlitz and Lewis County sites is 7% each, and the total impervious surface area for the Pierce County site is approximately 15 %. h. Proposed measures to reduce or control erosion, or other impacts to earth, if any: A detailed Geology Report has been prepared and is available for review upon request. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Also, a Stormwater Pollution Prevention Plan (SWPPP) has been prepared for this project and is available for review upon request. The SWPPP provides detailed measures to be taken to control stormwater and erosion on and from the site. The plan is designed to be a total, onsite stormwater control system. Standard erosion control techniques will be used to minimize erosion. Such measures will include: • Surface reclamation will involve the clearing of construction debris from the ROW to leave the soil in proper condition for planting. • On slopes, surface flow will be diverted by waterbars to a stabilized outlet using runoff diversions with a 2% outslope directed toward appropriate energy- dissipating structures. Waterbars shall begin and end in undisturbed vegetation or soil. Woody material (such as low shrubs) will not be removed, but rather placed back on the ROW with topsoil to provide a seed source and organic matter. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 9 SEPA Checklist March 2000 • Other measures to restore or improve surface drainage on the right -of -way might include tightlining discharge from water bars, diverting or collecting surface water coming onto the ROW, and tightlining onflow below the slope. • Where sediment can be transported onto a public road surface or other paved area by equipment or vehicles accessing or leaving the construction site, sediment will be removed from the road immediately by shoveling or sweeping and transported to a sediment - controlled disposal area. • Inspections of site conditions and verification of the BMPs will be conducted prior to anticipated storm events to identify areas that may contribute to sediment discharge; corrective actions will be made as required. ■ All erosion and sediment control measures will be inspected within 24 hours of each rainfall event of 0.5 -inch or more and every 14 calendar days from October 15 through April 15, up until the time that site stabilization is achieved. Between April 16 and October 14, inspections will be conducted every 30 days. During extended storm events, inspections will be conducted at least once every 24 hours. • Inspection reports will be completed after each inspection and included in the project file. Ineffective temporary erosion control measures will be repaired or replaced as soon as possible but no later than 24 hours after identification. • Williams will retain completed inspection forms for at least 3 years. • Revegetation using native seed mixtures and approved mulch will be performed as needed on areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation is satisfactorily established. If vegetation cover is not adequate, problems will be corrected by implementing special measures such as overseeding, mulching, or the use of erosion control blankets. • Significant amounts of sediment that leave the ROW will be cleaned up within 24 hours of their deposition and either (1) placed back onto the site and stabilized or (2) properly disposed. • Equipment, materials, and workers must be available to respond rapidly to BMP failures and emergencies. G Salvaged topsoil will be spread evenly over all areas to be reclaimed. • Following replacement, topsoil may be stabilized against wind erosion by use of mulches, surface soil sealers, and/or erosion control fabric. • Minimal grading will be required to establish staging areas. • Staging areas will be located in existing contractor yards; commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or other level areas where grading and vegetation clearing is not required. • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, and sediment traps to avoid substantial soil loss and displacement. • Baffle boards will be installed where needed on steep slopes. • Bank slopes will be armored with rock riprap where necessary.

If the side -slope cut is longer than 200 feet, an erosion control blanket will be used with reseeding. The cut slope will not exceed 1.5:1, and the fill slope will not exceed 2:1. • Any soil stockpiled next to trenches that is subject to erosion will be either located on the upslope side of the trench, protected using straw bale dikes or silt fences, or covered with plastic, as appropriate. • The contractor must have a minimum of eight straw bales on hand at all times for emergency sediment containment. • Existing roads will be repaired upon completion if additional disturbance is created from fiber optic line construction activities. • Steel casing will be installed using standard cut - and -cover trenching techniques. Trenches should be backfilled with select backfill and compacted. Trench plugs should be installed periodically within the trench to prevent piping of the backfill and to limit groundwater movements. Water trapped at the trench plugs should be captured in a French drain and tightlined below the ROW and off the potential landslide area. • In some landslide areas it may be possible to span the affected area by stringing the fiber optic conduit and line aboveground on poles. Poles within the landslide mass may also be feasible where the landslide plane is below the depth of embedment of the pole, allowing the pole to move with the landslide mass. • Site visits should be performed for all active and potentially active landslide areas. Site visits to potentially active landslide areas are necessary to confirm a preliminary evaluation that these areas are not currently active, as well as to mark the limits of areas where special construction will be required. • Where HDPE conduits have been installed by plow, the resulting furrowed soil will be leveled by compaction. For installation by drilling, any extra excavated material from the drilling not used for backfill will be hauled to an authorized offsite disposal area. For installation by open -cut trenching, the trench will be backfilled. ▪ All temporary soil erosion control measures will be removed within 30 days after final ROW stabilization is achieved. Trapped sediment and disturbed soil areas resulting from the removal of temporary measures will be stabilized to control further erosion and sedimentation. 2. AIR a. What types of emissions to the air will result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities, if known. Air emissions generated by the project will be temporary, resulting from construction activities associated with installation of the conduit, fiber optic line, and stations. Temporary air emissions will include particulates associated with fuel used in construction equipment, including plows, Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Ornroerrrirre 5*R rcrrf2Yi�+�.+�wwr _ 11 SEPA Checklist March 2000 drilling machines, and trucks. Emissions will also be produced by the infrequent operation of the emergency backup generator. Construction equipment, including backhoes, excavators, and trucks, will be used during construction. The heavy equipment will produce minor temporary air pollutants during the construction phase. A diesel - powered backup generator (maximum 255- horsepower) and aboveground and bermed fuel tank will be installed at each of the three OP -AMP stations to provide emergency backup power during operation. Emissions will be produced intermittently by use of these backup generators during power interruptions and for about 15 minutes each month during routine maintenance. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. No offsite emissions or odors have been identified in the vicinity of the proposed ROW. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Mitigation Measure AQ -1: Implement Construction Best Management Practices. Williams will use best management practices for construction activities, and will train work crews in those measures before beginning work. Please refer to the Best Management Practices in Appendix B for a detailed description of measures to be used to reduce impacts for all disciplines. • Water construction areas to minimize visible dust emissions. • When necessary, apply approved nontoxic chemical soil stabilizers according to manufacturer specifications to inactive construction areas (i.e., previously graded areas that remain inactive for 96 hours). • Reestablish ground cover on the construction site through seeding and mulching, as required for erosion control. • Maintain truck and equipment engines in good running condition to minimize exhaust emissions. • Clean equipment daily or as needed to reduce tracking of soil onto adjacent roads. • Clean adjacent roads daily or as needed to remove accumulated soil. • Limit maximum speed to 15 miles per hour (mph) on unpaved roads. Minimal grading operations are likely to occur, but these will be suspended if wind gusts exceed 25 mph. Williams Communications, Inc.

Is there any surface water body on or in the immediate vicinity of the site z (including year -round and seasonal streams, salt water, lakes, ponds, wetlands)? If yes, , = z describe type and provide names. If appropriate, state what stream or river it flows into. w Yes. Background research was conducted to develop a database of potential and previously -I p identified water resources in the immediate vicinity of the fiber optic line ROW. Sources of co ° background data include: W = • Initial meetings with state and municipal agencies to discuss the project and field and W o a report- writing methods; w J • Strip maps of the Williams natural gas pipeline ROW, which include survey data V- ca overlaid on aerial photographs; _ • Aerial photographs of the Seattle and Portland Laterals along the ROW; z • United States Geological Survey (USGS) topographic maps; 1--, O • National Wetland Inventory (NWI) maps; w • Federal Emergency Management Agency (FEMA) floodplain maps; ' 2 _ • Natural Heritage Program (NHP) threatened and endangered species maps; v t' • Natural Resources Conservation Service (NRCS) soil surveys; and o I-- • Washington Department of Natural Resources (WDNR) Stream Survey maps. v. Pertinent data were added to strip maps used in the field to help identify resources on the ground. z w u) The entire ROW was surveyed for Waters of the U.S. Biologists walked all parcels for which F. I the ROW acquisition agents had obtained access permission. For wetlands that extended beyond z the ROW boundaries, field crews visually estimated the size and condition of wetland areas. Within the project ROW, wetlands and streams were delineated and mapped on the aerial photograph basemaps and topographic maps. For wetland delineations, the project ROW included the 75 -foot wide ROW for the pipeline lateral, and a 30 -foot wide ROW that extended from the centerline of the nearest drivable road lane or from the centerline of the railroad line in the Portland and Seattle Laterals. Wetland delineations were made using the 1987 Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987) and the 1997 Washington State Wetlands Identification and Delineation Manual (Ecology 1997). The U.S. Army Corps of Engineers (Corps) applies the 1987 manual for implementation of Section 404 of the Clean Water Act. The 1997 Ecology method is utilized by Ecology for purposes of SEPA. Wetland functions and values were also assessed for wetlands within the ROW following methods in Wetland and Buffer Functions Semi - Quantitative Performance Assessment Methodology (Cooke 1997). Wetlands were rated using rating systems established by the applicable local jurisdiction. Biologists identified all drainages lying within the ROW. Stream channels were typed using the Washington State Forest Practices Rules (WAC 222 -16 -030) as modified by the Forest Practices Williams Communications, Inc.

WDNR Stream Typing maps were used in tandem with data collected in the field to classify streams. Wetlands A total of 107.24 of wetlands were delineated in the ROW within the state of Washington. Table 1 shows the number of acres of palustrine emergent (PEM), palustrine scrub -shrub (PSS), and palustrine forested wetlands (PFO), and open water (OW) that occur within the ROW for each county. Because of the disturbed condition of resources along most of the pipeline and road ROWs, the wetlands generally have similar vegetation, soil, and hydrologic conditions. Some portions of the ROW that have not been recently disturbed for road, railroad, or gas pipeline maintenance have a more developed vegetation structure of scrub -shrub or forested habitat. Emergent wetlands include wetlands found in depressions, hillside seeps, and lowland areas between rolling hills of southern Washington. Emergent wetlands are dominated by a mixture of exotic /invasive species such as reed canarygrass, birdsfoot trefoil, bluegrass, meadow foxtail, velvet grass, cattail, and creeping buttercup (see Appendix D for scientific names). Other common herbaceous species include small- fruited bullrush, meadow fescue, slough sedge, soft rush, toad rush, white clover, perennial ryegrass, and yellow parentucellia. Scrub -shrub wetlands are dominated by Douglas' spiraea with salmonberry, western crabapple, and nootka rose also commonly observed. Forested wetlands within the ROW are dominated by red alder with black cottonwood, western redcedar, Oregon ash, and big -leaf maple also observed in wetlands. Shrub and herbaceous understory vegetation is dominated primarily be the shrub and emergent vegetation described above. Functions of wetlands were evaluated only within the ROW because the disturbed ROW where project construction will occur can differ from surrounding areas as a result of repeated disturbances (Cooke 1997). The primary functions provided by wetlands within the ROW are: • Floodwater /stormwater control provided mainly by the larger wetlands located on relatively level terrain; • Wildlife habitat: some scrub -shrub or forested vegetation can provide some hiding or thermal cover; ponded areas can provide sources of drinking water for larger animals or breeding habitat for amphibians; • Natural biological functions: those wetlands with a dense herbaceous component provide a source of ecosystem primary production; and • Water quality improvement: emergent wetlands can serve to filter and retain sediments or nutrients.

The ROW lies within the Columbia River Basin and nine Water Resource Inventory Areas (WRIAs) in western Washington. A total of 212 rivers and streams cross the proposed fiber optic line ROW. A brief description of the proposed ROW in relation to major watersheds follows. For a detailed description of the proposed ROW, see Appendix A. The fiber optic line will cross under the Columbia River between Oregon and Washington at the Port of Vancouver near Matthews Point. The proposed route follows existing road ROWs to the existing Williams 18 -inch pipeline ROW; follows the pipeline ROW northeast to Highway 502; proceeds north along the Highway 502 ROW; and rejoins the main Williams Pipeline ROW. Through this segment of the line, the ROW lies within several drainages tributary to the mainstem Columbia River, the most significant being Salmon Creek. The line then follows the main Williams Pipeline ROW north through the Lewis and Cowlitz River basins (WRIA 27 and 26; tributaries to the Columbia River). Near where the Williams Pipeline ROW crosses Highway 12, the line will cross into the Chehalis River Basin (WRIA 23), which includes the Newaukum and Skookumchuck subbasins. Near Vail, the line within the pipeline ROW enters the Puget Sound basin, crossing the Deschutes River basin (WRIA 13) and then the Nisqually River basin (WRIA 11). Once the ROW crosses the Nisqually River basin there are two alternative routes: one continues on the pipeline ROW through Fort Lewis; the other involves installing the line in road ROW around Fort Lewis and then rejoining the pipeline ROW. Both alternatives occur in the Nisqually River basin. From Fort Lewis, the line continues north along the Williams Pipeline ROW to the Puyallup -White River basin (WRIA 10), then enters road ROWs. The line continues north on road ROWs through the Green/Duwamish River basin (WRIA 9) to the POP site in Seattle. A detailed Fisheries Report has been prepared and is available for review upon request. Williams Communications, Inc.

Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, the proposed fiber optic line will require work within 200 feet of the described waters. Work that will occur in or near waters is described below. z a: Wetlands QQ JV, The proposed fiber optic line will result in ground - breaking disturbance in lower quality co o wetlands from plowing the soil to install the fiber optic line.

In some cases, where wetland crossings are longer than the t=- ?' maximum drill length (approximately 750 feet), additional drill work areas may be g= o required within the wetland. In those cases, the drill areas will be set back from other Li u sensitive resources, such as salmonid- bearing streams, according to local regulations. - I O z Installation of the line will result in a total of 0.99 acre of groundbreaking disturbance to wetlands. Table 2 shows the acres of impacts for emergent and scrub -shrub wetlands by county. These impacts include the trenching of small wetlands that are dry during the construction period, as well as plowing the majority of the other wetlands. The groundbreaking disturbance due to plowing and trenching is a 1 -foot wide by 4 -feet deep corridor. Entry and exit drill areas vary in size but are typically 4 -feet by 4 -feet where the soil is disturbed. Typical drawings of construction methods are shown in Appendix C.

The plowing process results in the soil being tamped back into place by the tractor equipment immediately after the line is in the ground. Therefore the impact is temporary and the soil is immediately moved back into place. Very little vegetation is physically disturbed by the plowing, although roots will be severed and above ground plant material will be trampled or possibly pulled out of the soil in the plowed area. Drill work areas will result in the physical disturbance of the soil and temporary removal of vegetation. Brush cutting may be necessary in some of the Class 3 scrub -shrub wetlands that are not avoided (i.e., Class 3 wetlands not associated with a Type 1, 2, or 3 stream) to allow access for the plowing or trenching equipment. Vegetation impacts in wetlands will be temporary, because a majority of the plants that will be affected are nonnative grasses or forbs that readily revegetate, such as reed canarygrass and creeping buttercup. Shrub species such as alder and willow have the potential to regenerate from plant propagules left in the soil or from intact root crowns and cut stumps. Other aboveground impacts that will occur within the 30 -foot wide construction ROW through Class 3 and 4 wetlands include construction equipment and personnel that will crush plants or otherwise damage aboveground plant structure. Wetland soils could be slightly compacted, although the use of construction mats in saturated wetlands, as stated in Section 3(d), will minimize this soil disturbance. Mitigation measures used to reduce and minimize impacts on wetlands are summarized in Section B.3.d. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Avoidance of Class 1 and 2 wetlands; avoidance of Class 3 and 4 wetlands associated with Type 1, 2, and 3 streams; avoidance of inundated wetlands; and implementation of mitigation measures and BMPs will reduce and minimize impacts to a less than significant level.

Streams The proposed fiber optic line will avoid in -water work in all fish- bearing streams (i.e., Types 1, 2, and 3, and 4 if flowing at the time of construction) either by directional drilling under the drainage, or attaching the line to existing bridges. If conditions strictly prohibit drilling a particular stream, the Washington Department of Fish and Wildlife (WDFW) habitat biologist will be consulted to receive recommendations. Construction activities will be subject to specific avoidance windows to avoid sensitive species (see Appendix B). At a minimum, construction buffer widths for fish- bearing streams prescribed by each jurisdiction (Appendix B) will be maintained to protect fish - bearing surface waters. It is important to note that the proposed fiber optic line ROW lies entirely within previously disturbed corridors (i.e., pipeline, road, and railroad ROWs) in which buffer areas have already been drastically altered from natural conditions. In areas where the project will cross rivers or streams, the riparian vegetation consists almost entirely of shrubs, with occasional small trees. Conifers will not be removed within 300 feet of fish- bearing streams. To ensure that riparian buffers for Type 1, 2, and 3 streams are maintained, environmental monitors will be present to coordinate with construction crews, mark appropriate riparian buffer boundaries, and ensure that riparian buffers are protected from construction activity and equipment. Installation of the line across Type 4 and 5 streams (non - fish - bearing) may be completed by plowing if the streams are dry. Installation of the line across Type 5 streams (non -fish- bearing) may be completed by plowing, if the streams are dry or in low flow conditions at the time of construction. Because the proposed construction methods follow BMPs, erosion control methods, and because of the existing riparian vegetation conditions along the fiber optic line ROW, the project will not have a significant impact on riparian functions, or concomitant water quality or fish habitat. The following describes proposed construction methods, including BMPs and erosion control practices for river and stream crossings. Directional drilling will be used in various locations along the ROW to cross areas where surface disturbance must be avoided (e.g., fish- bearing or sensitive rivers and streams, high quality wetlands, cultural resources, railroads and highways). The length of directional drills can range from less than 100 feet to 750 feet, depending on the extent of the resource (e.g., width of the river or stream). To complete the directional drill, a work area is established on each side of the crossing (see Appendix C and detailed description of directional drilling techniques in B.3.c.2). Typical work areas for drilling equipment are relatively small, consisting of drill entry areas ranging from 2 feet by 2 feet to 4 feet by 4 feet. The work drill entry area for the Columbia River drill will be larger. It should be noted that Columbia River drilling work will be conducted within a previously disturbed area in the Port of Vancouver. Williams Communications, Inc.

H U' Lo w z =; O ~ z Work areas for river, stream, and wetland crossings will be located outside of the required county or city riparian buffers for fish- bearing or sensitive rivers and streams. Thus, for fish - bearing or sensitive streams, all riparian areas that currently provide shade and other riparian functions will remain intact. Additionally, any mature conifers within 300 feet of any stream channel will not be removed. Type 4 and 5 streams (non -fish- bearing streams) that do not feed directly to fish- bearing streams, may be plowed if streams are dry at the time of construction or contain little flow. Construction typicals for plowed stream crossings are included in Appendix C. Type 4 and 5 streams are relatively small. Construction through these drainages is relatively rapid (10 to 60 minutes) when plowing can be used for line installation. When plowing, the area directly disturbed by the plow is very small (approximately 1 -foot wide) where the plow furrows the soil and installs the conduit in one pass. Very little vegetation is physically disturbed using this method and, typically, vegetation recovers very rapidly (within the first growing season). Plowing results in no removal, dredging, or side - casting of soil. In a few instances, it may be necessary to install the line by open -cut trenching to cross Type 4 or 5 drainages that have physical characteristics (e.g., bank height, bank slope) that prevent use of a tractor plow. Open -cut trenching across seasonal and intermittent drainages will be executed using dry ditch -type crossings (i.e., temporarily damming or diverting water around the active construction area). Disturbed bank areas and channels will be stabilized immediately upon completion of the in- channel activity. Trench plugs may be installed in trenches where they intersect banks. Any bed or bank disturbance to Type 4 or 5 streams will be restored to pre - construction conditions upon project completion. This will include, where appropriate, recontouring and compacting the bed and bank to preconstruction conditions, installation of erosion control matting, and reseeding disturbed areas above the banks. Construction Best Management Practices (see Appendix B) will be used to minimize the potential for sediment transport to surface waters during and following installation of the line. A Stormwater Pollution Prevention Plan has been prepared for the proposed fiber optic line, including detailed descriptions of typical BMPs, and when and how they are to be applied. BMPs and erosion control measures for this project will be used to isolate active construction areas from surface waters, and to minimize the sediment concentration of surface runoff. Typical erosion control measures to be used as part of this project include installation of strawbales and silt fencing, water bars, and other structures that trap sediment or disperse overland flow (see a more detailed description of these methods in Section B.3.c of this checklist). The project also includes the use of environmental monitors who will coordinate with construction crews to ensure that all necessary BMPs are followed and erosion control measures are installed and functioning properly. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 19 SEPA Checklist March 2000 3. Estimate the amount of fill and dredge material that will be placed in, or removed from, surface water or wetlands and indicate the area of the site that will be affected. Indicate the source of fill material. No fill or dredge material will be placed in or removed from surface waters or wetlands. The z proposed project involves the installation of a fiber optic line along existing disturbed ROWs using construction methods that will not result in placement of dredge or fill material in wetlands w or streams. The proposed methods of installation are primarily plowing and drilling. These 6 = methods disturb the soil, but do not drastically alter the soil horizon, or require removal or v p addition of soil. The fiber optic line ROW lies within existing corridors, thus, no cut or fill construction will be needed. There may be an occasional need to install temporary fords on a few Type 4 and 5 streams to facilitate equipment crossing, protect stream beds and banks, and S ILL minimize erosion near surface waters. This will involve temporary placement of rock and o culverts or erosion mats in stream channels, which will be subsequently removed from the g stream bed following construction and installation of the line. It should be noted that temporary fords will only be used for equipment crossing at a few non -fish- bearing streams (see further = 3 discussion below). z LLI �- 0 The project includes the construction of three OP -AMP stations. The proposed location of these w F-; stations in Cowlitz, Lewis, and Pierce Counties will not affect any wetlands or streams. The 2 construction of OP -AMP stations will not result in the placement of dredge or fill material in o N wetlands or streams. o F- ill w 4. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. - z w 0 co No water withdrawal or diversion will be required. All water needed for the project will be o trucked to the construction sites from municipal sources or be provided directly from hydrants. z The proposed fiber optic line will not result in any permanent water diversions, but may require temporary diversion of water around construction sites at a small number of Type 5 streams, if construction occurs when streams are flowing. Type 4 streams may be plowed if they are dry and any bed and bank disturbance will be restored upon project completion. The only possible areas where temporary fords may be required will be through Type 4 and 5 streams. No Type 1, 2, or 3 (i.e., fish - bearing) streams will be forded. Fords are made of stabilizing material such as rock and will be used only where normal flow is shallow (i.e., less than 3 inches deep) or intermittent. Fords are especially appropriate for crossing small Type 4 or 5 drainages. When properly installed, fords offer little or no obstruction to flow, can safely handle heavy loads with minimal disturbance to bed and banks, and are relatively easy to install and maintain. Where fords are proposed for equipment crossings, the environmental monitor will coordinate with state and federal resource agencies to ensure avoidance of impacts on sensitive biological resources. 5. Does the proposal He within a 100 -year floodplain? If so, note location on the site plan. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 20 SEPA Checklist March 2000 ,Mp,r.!�a?YCacasmr Portions of the proposed fiber optic line ROW pass through floodplains. However, the proposed fiber optic line will have no effect on floodplain function or capacity because activities within floodplains will include only the underground installation of the line. There will be no aboveground facilities placed within 100 -year floodplains. Floodwaters will have no impact on operation of the project because the fiber optic line is designed for subsurface installation under water. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No discharge of waste materials is anticipated to result from this project. As with all construction projects, the potential exists for accidental spills of equipment - related materials. Hazardous materials associated with the project will be limited to those substances associated with construction equipment, such as gasoline and diesel fuels, engine oil, and hydraulic fluids. A spill of these substances could contaminate drainages, soils, wetlands, and other environmentally sensitive areas. However, the potential for accidental spills entering surface waters will be minimized through implementation of spill prevention and containment measures. A SWPPP has been prepared for the project and is available for review upon request. The SWPPP includes measures for a spill prevention and control plan that will be included as part of bid documents and construction specifications. The contractor will follow the SWPPP and perform measures to ensure that potentially hazardous substances are not discharged to surface waters. Staging areas for equipment and construction- related hazardous materials, and maintenance and fueling areas for equipment, will be located at least 150 feet from surface waters. The plan will include the names of responsible parties, emergency agency phone numbers to report accidental spills, methods to prevent spills during maintenance or fueling, specific requirements for storing and transporting materials, and spill containment and cleanup measures. In addition, the project includes the use of environmental monitors to ensure that spill prevention and control protocols are followed by the contractor. b. Ground: 1. Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities of withdrawals, if known. No. The proposed project will use water from municipal sources only. Waste or hazardous materials will not be discharged to groundwater. Spill prevention and containment measures (noted in B.3.a.6) will minimize the potential for hazardous or waste material to enter groundwater. 2. Describe waste material that will discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 21 �5�..ace+n: war.».• o.-...r.......,. � . ............................... SEPA Checklist March 2000 None. The project does not include the installation of septic systems or any other facility that will discharge waste material to groundwater. c. Water Runoff (including stormwater): 1. Describe the source of runoff (including stormwater) and method of collection and disposal, if any (include quantities, if know). Where will this water flow? Will this water flow into other waters? If so, describe. As with any construction project involving surface disturbing activities, there is potential to generate stormwater runoff. However, the project will result in very little additional runoff from areas affected by construction. The installation of the fiber optic line will not result in significant vegetation removal and will not add impervious surface. Soils in the affected areas will be recompacted to preconstruction conditions, and runoff rates from these areas will not be significantly altered from the existing conditions. Any stormwater flow generated in the construction area will be diverted away from surface drainages by implementing prescribed best management practices (Appendix B). For example, silt fences or straw bale dikes will be used to intercept and retain small amounts of sediment carried by sheet flow from disturbed areas during construction activities and to prevent this sediment runoff from leaving the project ROW. The silt fences or dikes will be placed in critical areas where high surface runoff is expected and around spoil piles in construction areas. On slopes, these devices will be placed perpendicular to the flow of runoff (i.e., parallel to the contour), except where there may be significant concentrated overland flow. Straw bale dikes, rather than silt fences, will be installed at locations where higher runoff volumes or sediment loads are expected. These measures will also be placed downslope of disturbed areas where sheet or rill erosion can occur. The measures will be used at the base of drainage banks and at storm drain inlets adjacent to construction areas. A Stormwater Pollution Prevention Plan has been prepared for the proposed fiber optic line and includes detailed descriptions of typical BMPs and when and how they are to be applied. 2. Could waste materials enter ground or surface waters? If so, generally describe. Construction equipment and access vehicles used to install the fiber optic line will require refueling and routine maintenance. The following measures, which are specified in the SWPPP, will be implemented to prevent waste materials, such as fuels and lubricants, from entering ground and surface waters. All onsite vehicles will be monitored for petroleum leaks and receive proper preventative maintenance to reduce the potential for petroleum leaks. Petroleum products will be stored in tightly sealed containers that are clearly labeled. Equipment fueling and maintenance will occur at least 150 feet from surface waters. Spill containment equipment will be readily accessible to the construction crew should an accidental spill occur. Any accidental spill will be cleaned up immediately. Waste oil and other petroleum products will not be discharged onto the ground or Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 22 SEPA Checklist March 2000 into water bodies. Petroleum products used onsite will be used according to manufacturers' recommendations. Petroleum products will be stored a minimum of 150 feet from waterways and wetlands, within prefabricated spill containment devices, earthen berms, or similar features. All waste material will be collected and stored in a secure container and removed from the project ROW. The waste container will be inspected regularly, and the contents will be disposed of properly by the construction crew. No waste oil or other petroleum -based products will be disposed of onsite (e.g., buried, poured), but rather will be removed offsite for proper disposal. Litter generated by the construction crew will be picked up and properly disposed of on a daily basis. When directional drilling requires the use of drilling mud (bentonite), no discharge of excess material or site runoff into drainages or wetlands will be allowed. The drilling fluid consists largely of a bentonite slurry. Bentonite is a swelling clay that is non - toxic. Slurry tanks will be sized to hold all excess material so that there is no spillage. The casing pipe entry point will be appropriately enclosed and equipped with a sump pump to reclaim excess slurry or discharge it to a reuse or disposal tank. Earth spoiled by drilling slurry will be removed and disposed of by the contractor, and replaced with clean material. Upon completion of construction, the ROW will be restored to a condition equal to or better than its original condition. The drill operator will maintain continuous visual inspection while the drilling operation is proceeding. When the drill goes beneath a drainage or wetland, a visual inspection will be made by the operators and the environmental monitor at the most accessible point immediately downstream of the drill site for changes in turbidity or color, which may indicate a fluid discharge into the drainage or wetland. If a surface release is detected, the slurry will be contained using straw bales or other appropriate measures. Recovered slurry material will be properly disposed. Use of guided drilling equipment can result in an accidental spill of drilling fluid into, or adjacent to, stream channels. Any bentonite spills delivered to surface waters will have the same effects as other forms of fine sediment delivered to surface waters — namely adversely affecting water quality by creating turbidity and potentially increasing the embeddedness of substrates in the affected stream reach. The potential for accidental discharge of bentonite to surface waters will be minimized by drilling at an adequate depth below surface waters; using the smallest practical equipment (to minimize drill hole pressures); and monitoring surface waters in the vicinity of each drilling operation. Environmental monitors will be present onsite during construction to ensure that BMPs for directional drilling are followed and that any problems (i.e., release of bentonite to the surface) is promptly detected and addressed. If a bentonite spill occurs, the equipment will be immediately shut down, the spill will be promptly cleaned up, and the appropriate office of WDFW and Ecology will be notified. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 23 SEPA Checklist March 2000 ,..., d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Measures to reduce impacts to surface water, groundwater, and runoff are summarized in the following paragraphs. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Mitigation Measure W -1: Minimize Disturbance and Restore Other Waters of the United States to Preproject Conditions. Consistent with the U.S. Army Corps of Engineers' (Corps') Nationwide Permit No. 12 for utility line discharges, the area of waters of the United States that will be disturbed will be limited to the minimum area necessary to successfully install the fiber optic line. The following measures will be implemented to minimize the effects on and restore other waters of the United States and associated plant communities: • Stabilize exposed slopes and streambanks immediately upon completion of construction activities. Other waters of the United States will be restored in a manner that encourages vegetation to reestablish to preproject conditions and reduces the effects of erosion on the drainage system. • Stabilize banks in highly erodible stream systems, using a nonvegetative material that will initially bind the soil and break down within a few years. If the project engineers determine that more aggressive erosion control treatments are needed, geotextile mats, excelsior blankets, or other soil stabilization products will be used. • Remove trees, shrubs, debris, or soils during construction that are inadvertently deposited below the ordinary high -water mark of drainages in a manner that minimizes disturbance of the drainage bed and bank. • Implement the measures identified in the WDFW Hydraulic Project Approval. These measures will be incorporated into contract specifications and implemented by the construction contractor. Additionally, Williams will incorporate all permit conditions into construction specifications. The contract compliance inspectors and biologists will routinely inspect construction activities to verify that the above protective measures and permit conditions have been implemented. Mitigation Measure W -2: Minimize Disturbance and Restore Jurisdictional Wetlands to Preproject Conditions. Williams will implement the following guidelines for reestablishing conditions conducive to natural site regeneration: • Avoid construction activities in saturated or ponded wetlands during the wet season (i.e., spring and winter) to the maximum extent possible. Where such activities are unavoidable, protective practices, such as the use of padding or vehicles with balloon tires, will be used. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington i if 474.^ 1.4r, • .r_ 24 SEPA Checklist March 2000 z w g 00. ND �I �u- w0 u. Q co =a z 1._ z° w ui O D. o I' wW U u—'O uiz = z • Where determined necessary by the resource specialists, geotextile cushions and other materials (e.g., timber pads, prefabricated equipment pads, or geotextile fabric) will be used in saturated conditions to minimize damage to the substrate and vegetation. • In wetlands that are trenched, the top 12 inches of topsoil from the excavated site, with roots, rhizomes, and seed bank intact will be stockpiled (the Corps' Nationwide Permit No.12 requires that topsoil be stockpiled and replaced). The topsoil and subsoil will be replaced immediately after construction activities are complete. • The ground surface will be recontoured to maintain the preproject wetland hydrology. Mitigation Measure W -3: Avoid and Protect Specified Jurisdictional Wetlands Adjacent to Construction Areas. Fiber optic line construction activities will be limited to the ROW in wetland areas. Protective barrier fencing or staking and flagging will also be used in specified wetland areas to protect wetlands near the work zone. Resource personnel will be present to identify the specific location of protective barriers before fiber optic line and OP -AMP station construction activities are initiated near specified jurisdictional wetlands. The contract inspectors and resource specialists will routinely inspect protected areas to ensure that barriers remain in place and are effective. Protective barriers will remain in place until all construction activities are complete in areas near sensitive resources. Mitigation Measure W -4: Implement Sediment and Erosion Control Measures. The following standard erosion and sediment control measures and practices will be used during and after construction to control accelerated soil erosion and sedimentation. • minimize vegetation and soil disturbance; • perform initial cleanup; • compact subsurface backfill material; • leave topsoil in roughened condition, except in road shoulders; • install trench plugs; • construct water bars; • install baffle boards; • where absolutely necessary, armor bank slopes with rock riprap; • perform seeding and mulching, as needed; • install erosion control blankets; • install silt fencing and straw bale dikes; and • conduct periodic maintenance of erosion and sediment control measures. A detailed description of specific sediment and erosion control measures and when and how they are to be applied are included in the BMPs outlined in Appendix B. In addition, an SWPPP has been prepared and is available for review upon request. Williams Communications, Inc.

Other types of vegetation: Other invasive weeds: creeping buttercup, Himalayan blackberry, bird's foot trefoil, white clover, and red clover. Overview of Vegetation along the ROW: The proposed ROW is approximately 176 miles long. It begins in Portland, Oregon, in an urban area, and proceeds north to the Columbia River. The fiber optic line will be drilled under the Columbia River and the drill areas will be set back to prevent the need to remove riparian vegetation on either side of the river. Along the length of the proposed ROW, sensitive river, stream, and wetland crossings will be similarly drilled. In Clark County, from the Columbia River, the ROW crosses an agricultural field and then follows the existing cleared ROW for Highway 501. As the ROW continues north, it enters a less urban area and passes through river -bottom lands containing wetlands and lakes. In the vicinity of the Shillapoo Wildlife Area, the ROW exits the existing Highway 501 ROW and follows the existing Williams natural gas pipeline ROW. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 26 SEPA Checklist March 2000 rvtt�?Fi`?NV: • :rW1.4mfix+' . The existing road and pipeline ROWs are maintained in an early seral condition, with tree and shrub growth controlled and invasive weed species common in the area. The existing pipeline ROW has been cleared of most woody vegetation. Trees that do occur within the existing ROW are primarily saplings. Hardwoods are dominant within forested areas adjacent to the ROW, although Douglas fir and western redcedar also occur. Disturbance to native plant communities from pipeline maintenance has allowed the invasion of many non - native species into the ROW. The ROW passes through primarily rural farmland and industrial forest areas as it proceeds north. In northern Clark County, pasture and agricultural fields dominate lands adjacent to the ROW. Where the ROW passes through forest land, Douglas fir, red alder, and big -leaf maple dominate. Stands of Garry oak also occur in isolated areas along the ROW. Wetlands occur along the length of the ROW, many dominated by invasive species such as reed canarygrass. As the ROW passes through Cowlitz County, Castle Rock, and Lewis County, the terrain has moderate relief and is predominantly agricultural, industrial forest, and rural residential land. Vegetation within the ROW consists predominantly of grass, shrub, and herbaceous species, with many noxious and invasive weeds occurring. In Lewis County, approximately 60% of the area adjacent to the ROW is forested, with second growth and recent clear cuts predominating. The remainder of the adjacent area is agricultural and rural, with pasture being most common. Garry oak woodland also occurs along approximately 1% of the area adjacent to the ROW. As the ROW passes into Thurston County, still within the existing Williams Pipeline ROW, it passes through moderately hilly terrain that is predominantly agricultural, industrial forest, and rural residential. As the ROW proceeds north, the terrain flattens and the ROW passes through historic prairie habitats, much of which has been converted to agricultural or pasture land. Within the ROW, grasses, native and introduced herbaceous species, and both native and introduced shrubs predominate. Where trees occur, they are in the sapling stage and are predominantly red alder. Wetland plant communities are predominantly herbaceous and include rushes, reed canarygrass, and small - fruited bulrush. In Thurston County, areas adjacent to the ROW are predominantly regenerating forest, with Douglas fir and mixed hardwoods (i.e., red alder and big -leaf maple) most common. Agricultural and residential lands also occur. Approximately 5% of the area adjacent to the ROW contains either Garry oak woodland or aspen forest. The proposed ROW in Pierce County follows either the existing Pipeline ROW or existing road ROWs. The terrain has very little relief. Upland vegetation communities within the ROW are dominated by native and introduced grass, herbaceous, and shrub species. Wetlands species include reed canarygrass, red alder, rushes, grasses, and Douglas spirea. Areas adjacent to the ROW are predominantly agricultural, rural, or developed land with fields and pastures most common. The ROW passes through the Cities of Puyallup and Edgewood, following roads through residential areas and past a golf course. In the Fort Lewis area, the ROW borders areas of both native grassland and late - successional Douglas -fir forest, although the ROW will be contained in existing road or pipeline ROWs. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 27 SEPA Checklist March 2000 In King County, the proposed ROW follows existing roads through the Cities of Federal Way, Kent, SeaTac, Tukwila, and Seattle. The land is dominated by suburban, light industrial, and urban land uses. The terrain has little relief. Where vegetation exists within the ROW, it is dominated by Himalayan blackberry, salmonberry, and saplings of red alder and Douglas fir. z Wetlands are dominated by reed canarygrass, red alder seedlings and saplings, Douglas spirea, z ,. salmonberry, and evergreen blackberry. Areas adjacent to the ROW are dominated by cultivated plants, Himalayan and evergreen blackberries, red alder, and Scots broom. 6 = b. What kind and amount of vegetation will be removed or altered? N W J H The majority of upland vegetation removed within the proposed ROW will be native and non- N w native grasses, herbaceous species, and shrubs occurring within the existing disturbed ROWs of w O the Williams Pipeline and existing roads, as previously described. The remainder of the g zi vegetation removed will be grasses associated with pasture land. 92a Because most streams will be drilled, the riparian vegetation will be removed only beyond the z III riparian buffer as described in Section B.4.d. The remaining streams will be trenched or plowed H 0 and the riparian vegetation associated with these streams is predominately early seral stage. w t- w Most wetlands within the ROW will be drilled and no wetland vegetation removal will occur in o N these areas. Some removal of wetland vegetation will occur in wetlands within the ROW that CI F—. will be plowed. The decision to plow these wetlands is based in part on their current condition, w w with plowing occurring only in low quality wetlands. Vegetation in these wetlands is I- I predominantly reed canarygrass. z CO U- Construction impacts on vegetation will occur within a designated 30 -foot wide construction - i ROW. Construction activities within the ROW will result in the removal of vegetation from z digging and grading; trampling of shrub and herbaceous vegetation by vehicles, construction materials, and workcrews; and potential breaking or damaging of branches of trees overhanging the ROW. Construction impacts will also include the potential damaging effect of compacted soils from vehicle use. Compacted soils may damage root systems of rooted plants and restrict infiltration of water into the soil. The majority of vegetation removal in conjunction with this project will be temporary and most vegetation will regenerate quickly on the site. Permanent vegetation removal will occur where OP -AMP stations are built and where manholes and handholes are located. One of the selection criteria for location of OP -AMP stations includes locating them in previously disturbed areas. Three OP -AMP station sites are planned, at a spacing of approximately 44 miles, and each site will be between approximately 2.5 and 5 acres in size. Handhole and manhole sites will be located within the ROW and are usually placed at intervals of 3 to 5 miles. Handholes measure approximately 30 inches wide by 48 inches long by 24 inches tall and manholes measure approximately 6 feet in diameter below ground, with a 36 -inch Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 28 SEPA Checklist March 2000 cover at ground level. Handholes and manholes will not be placed in areas identified during field surveys for this project as containing sensitive resources. The pipeline ROW currently is continually maintained in herbaceous and shrub vegetation. c. List threatened or endangered plant species known to be on or near the site. Only one listed plant species was found in the project ROW, white -top aster (Aster curtus). The vicinity of the ROW contains potential habitat for other threatened or endangered plant species, however none were located during field surveys for this project. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Vegetation within the fiber optic line ROW will be restored to pre - project conditions. Mitigation measures to limit impacts to vegetation along the ROW are summarized below. Measures to reduce impacts to surface water, groundwater, and runoff are summarized in the following paragraphs. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Mitigation Measure P -1: Retain Qualified Biologists and Resource Specialists to Monitor Construction Activities near Specified Sensitive Biological Areas. Williams will retain qualified biologists and other qualified resource specialists, as necessary, to monitor fiber optic line construction activities on each construction segment where sensitive resources have been identified. Biological monitors will locate and stake previously identified sensitive resources before construction activities begin in specified segments. Resource monitors /contract construction inspectors will patrol areas and work with contract compliance inspectors to ensure that barrier fencing, staking, and required setback buffers are maintained. They will also be responsible for monitoring installation activities in areas that support special - status species, woody riparian vegetation, wetlands, and perennial drainage crossings. Mitigation Measure P -2: Conduct a Biological Resource Education Program for Construction Crews and Enforce Construction Restrictions before Construction. Williams will conduct a brief biological resource education program for construction crews (primarily crew and construction foremen) before construction activities begin. The education program will include a brief review of the special - status species and other sensitive resources that can exist in the proposed project ROW (including their life history and habitat requirements), what portions of the project ROW these species may be found in, and their legal status and protection under the U.S. Endangered Species Act of 1973 (16 USC 1536). The program will also cover the environmental commitments /mitigation measures, environmental permits, and proposed project plans, such as a storm water pollution prevention plan. The crew foreman will be responsible for ensuring that crew members adhere to the guidelines and restrictions. Multiple education programs will be conducted as needed to inform appropriate new personnel brought on the job during the construction period. Williams Communications, Inc.

J-0 zt- U• CI ON O F— w • w. t- u: O .z w U= O~ z Mitigation Measure P -3: Avoid Substantial Impacts on Nonlisted Special - Status Plant Populations. Through coordination with Fort. Lewis, any white - topped aster (Aster curtus) plant populations that may be potentially impacted by the ROW or construction staging areas will be avoided. Based on the field inventory and the Department of Natural Resources data base, impacts of the proposed fiber optic line will not be significant based on the distribution of the species, the narrowness of the fiber optic line ROW, and other factors (e.g., timing of installation may avoid the plants' critical reproductive period). Mitigation Measure P -4: Confine Construction Equipment and Associated Activities to the Project ROW in Areas That Support Sensitive Resources. Construction equipment will be confined to a 30 -foot wide construction ROW in areas that support sensitive resources (e.g., riparian and wetland communities and sensitive species). During the environmental training program, construction personnel will be informed about the importance of avoiding ground - disturbing activities outside of the designated construction ROW. The contract compliance inspectors and environmental resource coordinator, with support from qualified biologists, if necessary, will ensure that construction equipment and associated activities avoid any disturbance of sensitive resources outside the fiber optic line ROW. Mitigation Measure P -5: Avoid the Dispersal of Noxious Weeds in the Fiber Optic Line ROW. To avoid the introduction or spread of noxious weeds into previously uninfested areas, the contract compliance inspectors, with support from resource personnel, will routinely inspect construction activities to verify that equipment is being cleaned of soil and plant matter at designated wash stations. Mitigation Measure P -6: Establish and Observe Exclusion Zones Around Riparian and Wetland Habitats That Support Special- Status Species. Before construction, qualified biologists will stake and flag exclusion zones around riparian and wetland areas based upon buffer setbacks specified by the local jurisdiction. Construction- related activities will be prohibited or greatly restricted within these zones. Essential vehicle operation on existing roads and foot travel will be permitted. All other construction activities, vehicle operation, material and equipment storage, and other surface - disturbing activities will be prohibited within the exclusion zone. Construction activities within an exclusion zone will be accomplished by drilling under the zone. In seasonal streams that potentially support special - status amphibians and where drilling is infeasible, Mitigation Measure A-1: "Avoid Disturbance to Special- Status Reptiles and Amphibians" (see Section B.5.D), will be implemented. Mitigation Measure P -7: Avoid and Minimize Disturbance of Woody Riparian Vegetation Along Drainages. Impacts on woody riparian vegetation will be avoided by drilling underneath drainages that support this habitat type. A buffer zone specified by each local jurisdiction will be established and staked by a resource specialist before construction activities begin. This buffer will extend between the edge of the woody riparian vegetation and construction equipment. In areas where drilling is infeasible, the field resource specialist will coordinate with the appropriate resource agencies to obtain clearance for cutting of woody riparian vegetation. Shrub vegetation will be cut at ground level to leave the root systems intact and allow for more rapid regeneration. Cutting will be limited to a minimum area necessary within the 30 -foot wide fiber optic line Williams Communications, Inc.

This type of removal will be allowed only for shrub species (trees will be avoided) and in areas that do not provide habitat for sensitive species. Before construction activities are initiated on a segment, the limits of the work zone will be identified by a qualified biologist. The environmental coordinator or contract compliance inspector will routinely inspect construction activities to ensure that protective measures are working and that they remain in place during installation. The contract compliance inspector also will confirm that protective measures are in place before construction activities begin on the ROW. Protective fencing will remain in place until all construction activities in the area are complete. Mitigation Measure P -8: Conduct Postconstruction Monitoring in Woody Riparian and Wetland Communities That Are Disturbed During Construction Activities. The proposed fiber optic line has been designed to avoid and minimize disturbance of woody riparian and perennial wetland communities because most of it occurs within existing disturbed ROWs. However, if woody riparian vegetation and wetlands are substantially disturbed during construction, the impact will be documented by a qualified biologist after construction activities are complete. The need for monitoring will be determined by a qualified restoration ecologist in conjunction with a WDFW resource specialist. Mitigation Measure P -9: Conduct Biological Clearance Survey of Staging Areas Before Construction and Implement Avoidance Measures if Required. If the selection of staging areas is changed to include locations that are not in previously disturbed areas that have not been subjected to biological surveys, these locations will be surveyed by a qualified botanist and wildlife biologist. The field inspection of the staging areas will be conducted before their construction as they are selected. If sensitive biological resources are identified at selected staging areas through consultation with WDFW or the appropriate agency, the area will be avoided and another location selected. 5. ANIMALS a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site (bolded below): The following species have been documented to occur within the mapping area of those U.S. Geological Survey (USGS) 7.5- minute quadrangle (quads) through which the proposed ROW passes. The species noted are included in the Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species (PHS) database. Birds: bald eagle, great blue heron, northern spotted owl, marbled murrelet, sandhill crane, Aleutian Canada goose, northern goshawk, peregrine falcon, pileated woodpecker, Vaux's swift, purple martin, western bluebird, osprey, green heron, regular concentrations of waterfowl, cavity nesting ducks, eastern wild turkey, and mountain quail. Mammals: black - tailed deer, black bear, Roosevelt elk, western gray squirrel, Roy prairie pocket gopher, and fisher. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 31 SEPA Checklist March 2000 K i Amphibians: Cope's giant salamander, Dunn's salamander, Columbia torrent salamander, Cascade torrent salamander, and Van Dyke's salamander. Invertebrates: Whulge's checkerspot and mardon skipper (butterflies). Fish: bass, herring, shellfish, Chinook salmon, coho salmon, sockeye salmon, chum salmon, pink salmon, steelhead, bull trout, sea -run cutthroat trout, resident rainbow and cutthroat trout, Dolly Varden, Pacific and river lamprey, sticklebacks, sculpins, and other non -game fishes occur in various rivers and streams in the vicinity of the proposed fiber optic line ROW. A list of the terrestrial species from the WDFW PHS data base that occur within the vicinity of the fiber optic line ROW is given in Appendix D. Appendix E identifies the sensitive fish species known to occur within watersheds of drainages crossed by the proposed ROW. Terrestrial Wildlife Field crews observed the above - listed terrestrial wildlife species within the fiber optic line ROW during field surveys for this project. A review of county ordinances and city municipal codes was conducted for this project to determine which terrestrial wildlife species warranted consideration for possible impacts as a result of the proposed project. Appendix D identifies those species and the jurisdictions in which they are regulated. Fish Appendix E lists all federal and state endangered, threatened, proposed, and candidate fish species known to occur in drainages crossed by the project ROW. No significant impacts to fish are anticipated to result from this project. Impacts to fish from construction activities typically result from either physical alteration of habitat (e.g., stream bed, bank, or riparian habitat) or indirectly through effects on water quality. Construction of the proposed fiber optic line will not directly affect fish habitat, or movement within streams. No construction will occur in fish - bearing streams (i.e., Type 1, 2, and 3 streams). All installations across fish- bearing streams will be completed by either directional drilling underneath the streams, or attaching the conduit and line to an existing bridge. The project will not result in significant changes to riparian habitat associated with fish - bearing streams. Because the proposed ROW lies almost exclusively within maintained ROWs, existing riparian vegetation at the point of crossing consists primarily of shrubs, small trees, and various grasses. No construction will occur within stream buffers specified by each county or city with jurisdiction. No conifers will be removed within 300 feet of fish - bearing streams. In addition, the construction methods used (i.e., plowing and directional drilling) result in a relatively small Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 32 SEPA Checklist March 2000 area of disturbance near each stream, which will return to pre - construction conditions rapidly (generally within a single growing season). No equipment fording will occur in fish - bearing streams. Water quality will not be significantly affected by the proposed fiber optic line. As noted in Section B.3, a number of BMPs (Appendix B) are included in the project to minimize sediment transport to surface waters. A SWPPP has been prepared for the proposed fiber optic line that identifies erosion control methods and how and where they are to be used. The plan also specifies a construction monitoring protocol for directional drilling, spill prevention and containment, and other pollution prevention and control measures. The SWPPP is available for review upon request. b. List any threatened or endangered species known to be on or near the site. A number of threatened and endangered wildlife species are known to occur within the general vicinity of the proposed fiber optic line ROW. This section provides a discussion of the known status of threatened and endangered species that may occur within or near the project ROW. Because the nature of habitats and resource concerns differs, terrestrial wildlife will be discussed separately from fish. Terrestrial Wildlife The following paragraphs describe the known status of federal and state threatened and endangered wildlife species that have been documented to occur in the general vicinity of the fiber optic line ROW. This list includes all such species known to occur within the mapping units of USGS 7.5- minute quadrangles through which the ROW passes, as reported in the WDFW PHS database. Each species is classified as Federally Threatened (FT), Federally Endangered (FE), State Threatened (ST), and/or State Endangered (SE). Northern spotted owl (FT /SE): The proposed ROW passes'through one known owl circle in Lewis County and through a designated Critical Habitat Unit (CHU) for spotted owls in Pierce County. A pair of spotted owls was reported in the Lewis County circle in 1993, however the circle has not been surveyed since that time and the current status is unknown (A. Potter personal communication). Suitable nesting, roosting, and foraging habitat is lacking where the proposed ROW crosses the circle in Lewis County, with land cover consisting of predominantly early seral, shrub and sapling vegetation or agricultural lands. In Pierce County, protocol surveys have been conducted and no spotted owls have been located (Department of Defense 1993). This area was designated a CHU with the knowledge that spotted owls did not occupy the area, but with the intent of providing a stepping -stone of spotted owl habitat between the Olympic and Cascade Mountain populations (Department of Defense 1994). The proposed ROW borders some potentially suitable habitat in the Fort Lewis area, however no habitat will be removed or altered by the project. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 33 SEPA Checklist March 2000 Bald eagle (FT /ST): Several known bald eagle nest sites and winter feeding and roost sites have been identified in the mapping area of the USGS 7.5- minute quadrangles through which the proposed ROW passes. In addition, potential feeding and roost sites were identified during field surveys conducted for this project. Bald eagle nest sites found to occur within 2,600 feet of the proposed ROW are listed in Table 3. Table 3.

These species include several Evolutionarily Significant Units (ESUs) of salmon, steelhead and sea -run cutthroat trout, and two Distinct Population Segments (DPSs) of bull trout. Salmonid species may use many of the streams crossed by the project ROW as migration, spawning, and/or rearing habitat. Critical Habitat has z been designated or has been proposed for designation for several of these species. River , _ drainages (hydrologic units) within the proposed ROW that have been designated as critical habitat for salmon include the Lower Columbia, Lewis, Cowlitz, Deschutes, Nisqually, Puyallup, W 2 and Duwamish river basins; Puget Sound; and Lake Washington (65 FR 7764, February 16, v o 2000).

I O Z The proposed fiber optic line will not have a significant impact on designated critical habitat. The project avoids construction in rivers and streams that can be potentially accessible to listed, proposed, and candidate fish species. The project will not affect juvenile or adult migration, or rearing or spawning areas. The project will also avoid work within county- and city- mandated riparian buffers, and will not significantly affect riparian function. Because the project does not include work in fish- bearing streams or their associated riparian buffers, and does not include creation of impervious surfaces, the project will not adversely affect water quality or quantity, stream temperatures, food resources, cover, or other habitat features essential to critical habitat for fish. A Biological Assessment (BA) has been prepared as part of compliance with Section 7c of the Endangered Species Act. The BA is available for review upon request. c. Is the site part of a migration route? If so, explain. Although designated stop -over habitat for migrating Aleutian Canada geese does not occur within the proposed ROW, Aleutian Canada geese are known to occur in the vicinity of the proposed ROW in southwestern Washington during the winter. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 36 SEPA Checklist March 2000 According to PHS data, the proposed ROW passes through habitat identified as regular concentration areas for elk and it is likely that elk migrate through the area in general. The proposed ROW is not a recognized migration corridor, however. d. Proposed measures to preserve or enhance wildlife, if any: Potential impacts to wildlife as a result of construction activities include temporary loss of habitat, permanent loss of habitat, disturbance to individuals, and loss of individuals. Temporary vegetation removal during construction of the proposed ROW will cause temporary habitat loss for those species that inhabit the proposed ROW. Permanent loss of habitat will occur where OP -AMP stations or handholes and manholes are constructed, as described in Section B.4.b. Several species have been identified as either occurring (according to the PHS database) or potentially occurring as winter residents or migrants in areas adjacent to the proposed project ROW. Noise and human activity associated with construction and maintenance activities may disturb these species, causing temporary displacement from the project area if the activity occurs during the season that the species are likely to be present. Both known and potential breeding habitat occurs in areas adjacent to the proposed ROW (according to the PHS database). Noise and human activity associated with construction and maintenance activities may disturb these sites. Where habitat for low - mobility species occurs within the proposed ROW, there is the potential for construction and maintenance activities to result in the loss of individual animals. As noted in Section B.5.b, many of the streams that lie along the ROW are known to serve, or may potentially serve, as migratory routes for juvenile or adult salmonids. The proposed fiber optic line will not affect salmon migration because no construction or fording of equipment will occur in fish - bearing rivers or streams (i.e., type 1, 2, or 3 streams), and no temporary or permanent structures, such as culverts, will be placed in fish - bearing waters. The measures discussed below have been developed to avoid or minimize potential impacts to wildlife from implementation of the proposed project. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. General Mitigation Mitigation Measure P -1: Retain Qualified Biologists and Resource Specialists to Monitor Construction Activities near Specified Sensitive Biological Areas. Refer to the discussion of this mitigation measure in Section B.4.d. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 37 SEPA Checklist March 2000 Wildlife Mitigation Mitigation Measure A -1: Avoid Disturbance to Special- Status Reptiles and Amphibians. At seasonal streams that support suitable habitat for non - federally listed special - status amphibians and reptiles and where drilling is infeasible, impacts will be avoided initially by determining presence or absence of these species, followed by construction of barrier fencing and relocation of individual animals during construction. Mitigation Measure A -2: Avoid Disturbing Active Special- Status Raptor Nests. To avoid potential adverse effects on nesting special - status raptors, Williams will establish a no- disturbance buffer zone around active nests. The size of individual buffers can be adjusted based on an evaluation of the site by a qualified raptor biologist. Factors to consider in revising buffer zones include: (1) the presence of topographical features or vegetation that obstructs the direct line of sight from construction activities to the nest; (2) the level of ongoing disturbance; and (3) the observed sensitivity of the birds to construction activities. Evaluations and buffer adjustments will be done in consultation with the local WDFW representative. The portion of the fiber optic line ROW that is within the designated buffer will be identified in the field by staking and flagging. If construction activities occur only during the nonbreeding season from August 1 to February 1, no buffer will be required. Mitigation Measure A -3: Fill or Cover Open Trenches. Any open trenches will be filled with earth or covered with plywood or other material at the end of each work day to prevent entrapment of wildlife. Both ends of any open trench will be sloped before covering to form escape ramps. If wildlife are found in the trench, they will be removed by a qualified and permitted biological monitor before resumption of work in that trench segment. Williams will specify this requirement in the agreements with all construction contractors. Mitigation Measure A -4: Avoid Disturbing Sandhill Cranes. The Williams- designated wildlife biologist will coordinate the timing of spring (early March through mid -May) and fall (mid- September to early November) construction and maintenance activities with WDFW to avoid disturbing migrating sandhill cranes in the Shillapoo/Vancouver Lake area. Mitigation Measure A -5: Avoid Disturbing Aleutian Canada Geese. The Williams - designated wildlife biologist will coordinate the timing of winter (mid- September to early March) construction and maintenance activities with WDFW to avoid disturbing wintering Aleutian Canada geese in the ShillapoofVancouver Lake area. Mitigation Measure A -6: Avoid Impacts to Bald Eagles. The following measures will be taken to avoid impacts to bald eagles: 1. No construction activity will occur within 2,600 feet of an open nest or 1,300 feet of a screened nest between January 1 and August 15, unless individual consultation with a WDFW biologist determines that the buffer can be reduced. 2. Between November 1 and April 1, no construction activity will occur within 328 feet of winter roosts during the time period between 1 hour before sunset and 1 hour after sunrise. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 38 SEPA Checklist March 2000 3. Within 2,600 feet of known nesting sites, communal roost sites, or areas of potential foraging habitat, no large cottonwood or Douglas fir trees suitable for use as perching or roosting habitat will be removed. 4. No new roads will be constructed in conjunction with this project. z re w Mitigation Measure A -7: Avoid Disturbing Spotted Owl Critical Habitat. No trees will be removed within designated critical habitat. All construction will occur within the existing ROW. _10 No trees will be removed within the existing spotted owl management circle. cn 0 w= Mitigation Measure A -8: Avoid Impacts to Mardon Skipper Habitat. Herbicides will not be w u used for vegetation control in prairie habitats where mardon skippers have been documented. w 0 Mitigation Measure A -9: Minimize Impacts to Oregon Spotted Frog. Although the Oregon spotted frog has not been documented within the ROW, the following measures have been D. c� developed to avoid or minimize potential impacts to Oregon spotted frog habitat. f- _ zF.. • Directional drill wetlands containing potential suitable habitat. z g uj • Do not flood or dra areas of potential habitat. 2 in • Within areas of potential hibernation habitat, do not disturb or alter muddy substrates. v °. O- Fish Mitigation w 1=-V Mitigation Measure F -1: Avoid in -Water Construction in Flowing Streams That Support z Sensitive Fish Species at or Below the Crossing Location. To avoid impacts to listed fish w u) species, Williams will not use in -water construction methods (i.e., trenching or plowing) to cross i= streams that are flowing at the time of construction, and which support sensitive fish species at or z downstream of the crossing location. At flowing sensitive stream crossings, Williams will install the fiber optic line by drilling under the stream, attaching the conduit to an existing bridge, or installing the conduit under or over an existing culvert to avoid impacts to listed fish species. Mitigation Measure F -2: Avoid Sensitive Fish Resources. Sensitive resources will be avoided through various means identified during the project design phase. Avoidance measures will occur in the field during construction as a result of preconstruction surveys or at the direction of construction inspectors. The construction technique will be coordinated through a monitoring resource specialist familiar with the resource issue being avoided. Typical avoidance measures include minor rerouting of the fiber optic line around the sensitive resource within the disturbed ROW, directional drilling under the resource, or attaching the fiber optic line to an existing bridge. Mitigation Measure F -3: Avoid Impacts in Sensitive Drainages. Significant impacts will be avoided at sensitive drainages, including perennial stream crossings or streams that are flowing at the time of construction and have sensitive resources located at or downstream of the crossing. At all streams that provide important habitat, contribute significantly to water quality, or support sensitive or listed aquatic species, the fiber optic line will be installed either by directional Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 39 SEPA Checklist March 2000 drilling under the drainage or by attaching the cable to bridges, where available. In many situations, these methods will also be used for wetlands. The avoidance methods for each sensitive resource will be shown on the construction drawings. 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Electricity will be used to power the OP -AMP stations, including the station equipment, lighting, heating, ventilation, and air conditioning. Each station will include a diesel - powered emergency backup generator that will be maintained for use during power outages. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. The fiber optic line will be installed underground and therefore will not affect the use of solar energy at adjacent properties. The proposed OP -AMP stations will not affect the potential use of solar energy by adjacent property owners because each station will not exceed one story in height (approximately 11 feet). c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: No additional energy conservation features are proposed beyond those required by building codes for similar types of structures. 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. The project will not require long -term storage, treatment, disposal, or transport of hazardous materials, beyond a diesel storage tank, which will meet appropriate codes. However, small quantities of hazardous materials will be stored, used, and handled during construction. The hazardous materials anticipated to be used are small volumes of petroleum hydrocarbons and their derivatives (e.g., gasoline, oils, lubricants, solvents) required to operate the construction equipment. The equipment used for the proposed fiber optic line will need periodic maintenance and refueling. These activities will be accomplished responsibly, using prescribed spill prevention and countermeasure procedures. No refueling or servicing will be done without absorbent material or drip pans underneath to contain spilled fuel. Any fluids drained from the machinery Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 40 SEPA Checklist March 2000 f.: during servicing will be collected in leak -proof containers and taken to an appropriate disposal or recycling facility. If these activities result in damage to or accumulation of a product on the soil, it will be assessed and disposed of properly. Under no circumstances will knowingly contaminated soils be added to a spoils pile. 1. Describe special emergency services that might be required. No special emergency service requirements are expected for this project. Fire prevention and response plans will be submitted to the appropriate regulatory agencies for the portions of the ROW that along which they are required. 2. Proposed measures to reduce or control environmental health hazards, if any: Measures that will be taken to minimize risks to environmental and human health are summarized below. . Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Mitigation Measure EH -1: Ensure Proper Labeling, Storage, Handling, and Use of Hazardous Materials. The construction contractor will ensure proper labeling, storage, handling, and use of hazardous materials in accordance with BMPs (Appendix B) and the Occupational Safety and Health Administration's (OSHA's) HAZWOPER requirements. The construction contractor will ensure that employees are properly trained in the use and handling of these materials and that each material is accompanied by a material safety data sheet. Additionally, any small quantities of hazardous materials placed temporarily in staging areas will be stored on pallets within fenced and secured areas and protected from exposure to weather. Incompatible materials will be stored separately, as appropriate. Mitigation Measure EH -2: Ensure Proper Training of Construction Crews and Plan Compliance. To avoid unexpected releases of hazardous materials, the construction contractor crews will include individuals trained in accordance with OSHA's HAZWOPER requirements. Additionally, the construction crews will have a written plan outlining how to respond if hazardous materials are unexpectedly encountered or revised. The plan will specify procedures for identification, handling, reporting, and disposal of hazardous materials. All hazardous waste materials removed during construction, to the extent necessary to ensure the area can be safely traversed, will be handled and disposed of by a licensed waste disposal contractor and transported by a licensed hauler to an appropriately licensed and permitted disposal or recycling facility. Williams will require in its contracts that contractors meet federal, state, and local regulatory requirements and maintain all required licenses and permits. b. Noise 1. What types of noise exist in the area which may affect your project (for example: traffic, equipment construction operation, other? The project will be located in a combination of rural and urban environments. The rural areas have background noises consisting of traffic on local streets and occasional aircraft overflights. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 41 SEPA Checklist March 2000 The urban environments have background noises consisting of traffic, public transportation, and occasional aircraft overflights. 2. What types and levels of noise will be created by or associated with the project on a short -term or a long -term basis (for example: traffic, construction operation, other? Indicate what hours noise will be generated by the site. Project- related noise during the installation phase will result from the operation of construction equipment and support equipment. Typical construction equipment likely to be used for construction of the fiber optic line system will include rubber -tired backhoes, tractors, caterpillars, and trenching and drilling equipment. Leveling the site is expected to be the noisiest activity associated with construction of each OP -AMP station. Construction equipment typically produces noise levels of 80 to 85 dBA at a distance of 50 feet from the construction activity, lasting only for the duration of the construction period. Construction noise will be audible at the residences surrounding the Cowlitz County site. The Lewis County site has no residences in the immediate vicinity and the Pierce County site is in a commercial area. All construction activity will occur during daylight hours. After construction, there generally will be no operational noise associated with the OP -AMP stations. Occasionally, the emergency backup generator will operate, including when electrical service is temporarily interrupted and about 15 minutes each month while maintenance occurs. No impacts to surrounding residences are anticipated from this temporary service. j 3. Proposed measures to reduce or control noise impacts, if any: Measures to minimize impacts of noise due to installation and operation of the fiber optic line are summarized below. . Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Mitigation Measure N -1: Employ Noise - Reducing Construction Practices. When installing and constructing the fiber optic line system, Williams will employ the following noise - reducing measures: • Restrict construction activity within 1,000 feet of residences to daylight hours (7:00 a.m. to 7:00 p.m.). No construction will be performed within 1,000 feet of an occupied dwelling unit on Sundays, legal holidays, or between the hours of 10:00 p.m. and 7:00 a.m. on other days. • All equipment will have sound- control devices no less effective than those provided on the original equipment. No equipment will have an unmuffled exhaust. • As directed by the local jurisdiction, Williams will implement appropriate additional noise mitigation measures to comply with the applicable local noise ordinance Such measures could include, but are not limited to, changing the location of stationary construction equipment, shutting off idling equipment, rescheduling construction activities, notifying adjacent residents in advance of construction work. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 42 SEPA Checklist March 2000 Mitigation Measures N -2: Design and Locate Emergency Backup Generators to Limit Noise from the Generator Engine. Williams will design and locate the emergency backup generator at each OP -AMP station so that noise produced by the generator engine does not exceed local noise ordinance criteria. Potential methods for achieving this include locating the facility away from noise - sensitive uses and using local shielding from the building structure, topography, or sound walls to reduce noise transmission to sensitive receptors. W. Mitigation Measure N -3: Limit Use of Helicopters near Residences and Other Sensitive Land Uses. If needed, Williams will locate helicopter staging/landing areas away from -J o residences and other sensitive land uses. Except when operating from an existing airport, cn C cn helicopter staging/landing areas will be located at least 1 mile from sensitive land uses. LLI 8. LAND AND SHORELINE USE w O a. What is the current use of the site and adjacent properties? ca The ROW has multiple uses because it crosses several jurisdictional boundaries. The most =- _ common uses include agricultural, high - density urban land, road ROW, military reservation, and Z natural gas pipeline ROW. w o 2 b. Has the site been used for agriculture? If so, describe. v O •4, ° !- The ROW crosses some areas used for agriculture, including pastureland and corn and hay fields. w w. i U- c. Describe any structures on the site. L` z'; U �. The fiber optic line ROW mainly follows the existing cleared Williams Pipeline ROW and existing streets and roads. With few structures, where necessary, the line will be installed, z drilling under roads and other structures and these will not be disturbed. There are no existing structures on the proposed OP -AMP station sites in Cowlitz, Lewis, and Pierce Counties. d. Will any structures be demolished? If so, what? Because the project is using existing ROWs and undeveloped properties, no structures will be demolished as a result of the project. e. What is the current zoning classification of the site? There are multiple zoning classifications because the project crosses several jurisdictional boundaries. The general zoning classifications include rural, urban, industrial, commercial and agricultural. There are no zoning designations for the OP -AMP station sites in Cowlitz and Lewis Counties. The zoning designation for the OP -AMP station site in Pierce County is EC, employment center. f. What is the comprehensive plan designation of the site? Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 43 SEPA Checklist March 2000 There are multiple comprehensive plan designations because the project crosses several jurisdictional boundaries. g. If applicable, what is the current shoreline master program designation of the site? The project ROW crosses several rivers with master program designations. The shoreline master program designations are as follows: Clark County Not determined Lewis County Mill Creek and Lacamas River — Conservancy South Hanaford Creek — Rural Dillenbaugh Creek and Salzer Creek — Urban Environment Cowlitz County Lewis — Rural or Urban Toutle — Conservancy Coweeman — Rural Kalama -- Conservancy Thurston County Deschutes River, Skookumchuck River, and Nisqually River — Conservancy Pierce County Puyallup River — Rural Nisqually River — Conservancy City of Puyallup Puyallup River — Urban Environment City of Tukwila Duwamish River — Urban The fiber optic line will be installed across rivers by directional drilling under the river or by attaching the line to an existing bridge. For directional drilling, drill entry and exit points will be located outside of buffer zones specified by the appropriate jurisdictional authority. Installation of the fiber optic line will be compatible with current master program designations for all rivers crossed by the line. Williams Communications, Inc.

O ~. z h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. Based upon the definition of "sensitive areas" in the local critical/sensitive areas ordinances, wetlands, rivers /streams, salmonid habitat, and known bald eagle -use sites occur within and adjacent to the fiber optic line ROW. The majority of these sensitive areas will be avoided by directional drilling, applying best management practices, and implementing appropriate construction windows. Other impacts to sensitive areas will be minimized as discussed previously in Sections B.1, B.3, B.4, and B.5. i. Approximately how many people will reside or work in the completed project? None. After construction, the OP -AMP stations and the fiber optic line ROW will be visited by two maintenance workers only for routine maintenance of the ROW, OP -AMP stations, and other tasks. No workers will reside within the project facilities. j. Approximately how many people will the completed project displace? There will be no residential displacements as a result of this project because the majority of the project is a buried fiber optic line. The OP -AMP stations will not cause residential displacement because the sites are undeveloped. k. Proposed measures to avoid or reduce displacements impacts, if any: No measures are proposed to reduce displacements because the project will not create displacements. 1. Proposed measures to ensure the proposal is compatible with existing and projected land use and plans, if any: The following measure will be implemented to ensure compatibility with existing and future land use plans. Mitigation Measure LU -1: Obtain and Comply with Local Zoning Permits. Williams will obtain necessary local zoning permits prior to construction of facilities and will comply with the applicable conditions of approval. 9. HOUSING a. Approximately how many units will be provided, if any? Indicate whether it will be high, middle, or low- income housing. No housing will be provided by the project because no permanent housing is needed, and existing sources of temporary housing are adequate to meet the minimal needs of the small construction crews. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 45 SEPA Checklist March 2000 b. Approximately how many units, if any, will be eliminated? Indicate whether it will be high, middle, or low- income housing. No housing units will be eliminated by the proposed fiber optic line because the majority of the Z project is a buried fiber optic line. The OP -AMP stations will be located on undeveloped lots. w a!2 c. Proposed measures to reduce or control housing impacts, if any: J QQ = U No measures are proposed to control housing impacts because no housing impacts will occur as a u) o result of the project. w = J �• • LL w 0 10. AESTHETICS g a. What is the tallest height of any proposed structure(s), not including antennas or = d chimneys; what is the principal exterior building material(s) proposed? _ The tallest structures are the buildings at the OP -AMP stations, which will be approximately 11 a feet tall. OP -AMP stations will be constructed of precast concrete. The fiber optic line will be buried, and will consist of no aboveground structures. N' 0 O E- b. What views in the immediate vicinity will be altered or obstructed? w w • U The proposed OP -AMP station site in Cowlitz County will be visible from a residence to the V—" 0 south of the project site. The proposed OP -AMP station site in Lewis County will not alter or v u obstruct views because no residences are in the immediate vicinity. The proposed OP -AMP i station site in Pierce County is located adjacent to site, on the southeast side of, the commercial z facilities. c. Proposed measures to reduce or control aesthetic impacts, if any: No measures are proposed to reduce aesthetic impacts because no significant aesthetic impacts are expected. 11. LIGHT AND GLARE a. What type of light or glare will the proposal produce? What time of day will it mainly occur? The proposed OP -AMP stations will have a small light over each door. No other lighting is proposed. b. Could light or glare from the finished project be a safety hazard or interfere with views? Williams Communications, Inc.

The small door lights at the OP -AMP stations will not create a safety hazard or interfere with views of nearby residences or commercial operations. c. What existing off -site sources of light or glare may affect your proposal? The fiber optic line will be installed belowground, and the proposed OP -AMP stations will be unstaffed. Off -site sources of light or glare will not affect the project. d. Proposed measures to reduce or control light and glare impacts, if any: No additional measures to control light and glare are proposed for the project. 12. RECREATION a. What designated and informal recreational opportunities are in the immediate vicinity? There are no designated recreational opportunities in the immediate vicinity. Informal recreational opportunities along the ROW may include hiking or horseback riding. These informal uses will not be affected, except for a brief interruption during installation of the fiber optic line. b. Will the proposed project displace any existing recreational uses? If so, describe. The project will not displace any existing recreational uses because there are only incidental recreational opportunities and construction will progress quickly in any given segment. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: No measures are proposed because no noticeable impacts were identified. 13. HISTORIC AND CULTURAL PRESERVATION A list of potential cultural and historic resource sites is given in Appendix F. a. Are there any places or objects listed on, proposed for, or eligible for listing in national, state, or local preservation registers KNOWN TO BE on or next to the site? If so, generally describe. Two previously recorded hunter - fisher - gatherer archaeological sites, 45CL55 and 45CL79, are at least partially within the right -of -way for this project (Appendix F, Table 1). The sites are eligible for listing in the National Register of Historic Places (NRHP) as contributing elements of Vancouver Lake's Archaeological District, which was determined eligible for listing in the NRHP on May 28, 1982. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington • 47 SEPA Checklist March 2000 Six historic structures eligible for listing or listed in the NRHP are adjacent to the proposed right - of -way (Appendix F, Table 2). Two structures, the Hotel Publix and the Buty Building/Idaho Hotel, are contributing elements of the Seattle Chinatown Historic District and are in the City of Seattle International Special Review District. b. Generally describe any landmarks, or evidence of historical, archaeological, scientific, or cultural importance known to be on or next to the site. There are two previously recorded hunter - fisher - gatherer archaeological sites, 45CL498 in Clark County and 45PI412 in Pierce County, in the right -of -way for this project (Appendix F, Table 3). Site 45CL498 is a lithic scatter that was recorded in 1999 by Archaeological Investigations Northwest, Incorporated, within the boundaries of Vancouver Lake's Archaeological District, but has not been evaluated for NRHP eligibility. Site 45PI412 is a lithic scatter that has not been evaluated, but was considered probably not eligible for listing when it was recorded by Historic Research Analysts in 1994. Three other potential sites are on the proposed right -of -way for the project: one previously recorded multiple- component, hunter - fisher- gatherer and historic period archaeological site, 45LE427, in Lewis County; and two previously recorded historic period archaeological sites, 27 -3832 and 27 -3823, both historic homesteads in Pierce County (Appendix F, Table 3). None of these five sites has been evaluated for eligibility for listing in the NRHP. Thirty historic properties were previously recorded along or adjacent to the proposed fiber optic LINE ROW in Clark, Pierce, and King Counties (Appendix F, Table 4). Three structures, the Yassui - Barham House, the William and Amanda Lindquist Place, and the William Ostrem House, were determined not to be eligible by the Washington State Office of Archaeology and historic Preservation (OAHP). The remaining 27 historic properties were not evaluated for listing in the NRHP (Appendix F, Table 4). c. Proposed measures to reduce or control impacts, if any: Any possible impacts to historic structures will be avoided by maintaining an adequate distance from the structure during construction excavation. The project will not alter the interior or exterior of the structures, and will not impact the structural or other integrity of the buildings. The proposed fiber optic line ROW will intersect the Yelm Irrigation Ditch in Thurston County. Consultation with Thurston County Advance Planning and Historic Preservation personnel and the City of Yelm determined that extant flume elements, made of wood or concrete, will be of interest, however, the ditch depression itself is not of interest. No extant flume elements were identified during field reconnaissance. Two of the archaeological sites, 45CL498 and 45CL79, will be avoided by restricting construction excavation to the roadfill of Highway 501. Other archaeological sites along the right -of -way will be avoided by drilling under the sites. By drilling at least 4 to 6 feet under the sites and 100 feet on either side of the center of the sites, a buffer will be maintained that will eliminate any possible impacts to the integrity of the sites. Site 27 -3823 is on Fort Lewis Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 48 SEPA Checklist March 2000 Military Reservation, and requires at least a 165 feet buffer on either side of the site as requested by the Fort Lewis Installation Cultural Resources Manager. Additional mitigation measures to minimize potential adverse changes in the significance of historical or archaeological resources are summarized below. Please refer to the Best Management Practices in Appendix B for a detailed description of measures to be used to reduce impacts for all disciplines. Mitigation Measure HC -1: Conduct Cultural Resources Clearance Survey of Staging Areas before Construction of Such Roads and Areas and Implement Avoidance Measures if Required. Field inspection of staging areas will be conducted before their construction, as they are selected, if cultural resources are suspected. An archaeologist will survey staging areas where cultural resources may be present. If cultural resources are identified, the area of the find and an area within 100 feet of identified cultural resources will be avoided in consultation with the archaeological monitor, OAHP, and potentially affected tribes, and another location will be selected. Williams will commit to enforcing its contract to ensure the construction contractor complies with these requirements. Implementation of this mitigation measure will result in avoidance of a substantial adverse change in the significance of a historical or archaeological resource in potential staging areas. Mitigation Measure HC -2: Stop Work If Cultural Resources Are Discovered During Ground - Disturbing Activities. If buried cultural resources, such as chipped or ground stone, historic debris, building foundations, or human bone, are inadvertently discovered during ground - disturbing activities, work will stop in the immediate vicinity of the find until a qualified archaeologist can assess the significance of the find and, if necessary, develop appropriate treatment measures in consultation with OAHP, the potentially affected tribe, and other appropriate agencies. Implementation of this mitigation measure will result in avoidance of a substantial adverse change in the significance of historical or archaeological resources that could be inadvertently discovered during construction. Mitigation Measure HC -3: Retain a Qualified Archaeologist to Oversee Construction Activities and Prepare a Report. In areas of known high sensitivity for archaeological resources, full -time monitoring by a qualified archaeologist may be required, based on the construction method used. In areas of moderate or low sensitivity, spot checking may be required. In areas of no sensitivity, no monitoring will be required. The archaeologist will monitor ground - disturbing activities and salvage and catalogue artifacts as required. In areas with high or medium sensitivity, the qualified archaeologist will be present at the preconstruction conference; will establish procedures for archaeological resource surveillance; and will establish, in cooperation with the contract compliance inspectors and environmental resource coordinator, procedures for temporarily halting or redirecting work to permit sampling, identification, and evaluation of sites. Archaeologists will be available and equipped to salvage artifacts as they are unearthed to avoid construction delays and remove samples of sediments. Archaeologists will be able to temporarily halt or divert construction equipment to allow removal of large specimens. The Williams Communications, Inc. Fiber Optic Line System installation Project Portland, Oregon to Seattle, Washington 49 SEPA Checklist March 2000 qualified archaeologist, in cooperation with the contract compliance inspector and environmental resource coordinator, will determine appropriate actions to ensure proper exploration and salvage of encountered historical cultural resources. Any significant finds will be offered to the appropriate repository. z If major historical or cultural resources are encountered that require long -term halting or redirecting of construction or that cannot be collected during normal monitoring time, salvage w cem operations will be initiated and completed as quickly as feasible at the direction of the qualified archaeologist and coordinated with the construction contractor. The environmental resource v o coordinator will be notified as soon as possible regarding any salvage operation. co w z` Implementation of this mitigation measure will result in the salvage of unique historical or o cultural resources, should they be encountered. w 2 u_< 14. TRANSPORTATION = a a. Identify public streets and highways serving the site, and describe proposed access to the z existing street system. Show on site plans, if any. w I- w The proposed fiber optic line ROW will follow the existing ROW of the following public streets, o roads, and highways: 0 p'. O I-- = w; • Highway 501 in the City of Vancouver and Clark County; 1- �. • NE 10th Avenue in the City of Vancouver and Clark County; u" O • Roy Petit Road, Harts Lake Loop Road, Goodacres Road, Pole Line Road, Mountain v �` Highway East, and 208th Street in Pierce County; F- • Wildwood Drive, 23rd Avenue, 17th Street, 19th Avenue, 21st Street, Pioneer Way, 23rd Street, Main Street, and Milwaukee Avenue in the City of Puyallup; • Todd Road in Pierce County; • North Meridian Road in the City of Puyallup; • Dechaux Road and North Meridian Road in the City of Edgewood; • Military Road in King County and the City of Federal Way; • 272nd Street in the City of Kent; • Military Road in the City of SeaTac and the City of Tukwila; and • Marginal Way, 4th Avenue South, Industrial Way, 6th Avenue South, Airport Way, and 5th Avenue South in the City of Seattle. Access to the portion of the route following the existing Williams Pipeline ROW will be by a combination of public roads, streets, and highways, including both improved and unimproved roads. The public street serving the Cowlitz County OP -AMP station site is Lady Blue Lane. The public street serving the Lewis County OP -AMP station site is Centralia -Alpha Road, and the public street serving the Pierce County OP -AMP station site is Canyon Road. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 50 SEPA Checklist March 2000 b. Is the site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? The ROW crosses several jurisdictional boundaries, most of which are served by local public transportation along the road ROWs. c. How many parking spaces will the completed project have? How many will the project eliminate? When completed, the OP -AMP stations will be gated and fenced for security purposes. Adequate parking will be available within the fenced portion of the stations for maintenance vehicles. The project will not eliminate any parking spaces. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). Minor improvements to access roads may be required. These requirements will be determined prior to construction. e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. The fiber optic line ROW crosses the Columbia, Willamette, and other rivers, which support commercial and recreational water traffic. The line will be installed across the Columbia and Willamette Rivers by drilling underneath them. This approach will result in no impact on shipping or recreational boating. The line will be installed across other rivers by drilling underneath or by attachment to existing bridges. Where the fiber optic line crosses a rail line, the line will be installed by directional drilling underneath the rails. Rail transportation will not be affected. The fiber optic line will not pass through any commercial air traffic facilities. The project will not use an water, rail, or air transportation facilities. f. How many vehicular trips per day will be generated by the completed project? If known, indicate when peak volumes will occur. The fiber optic line ROW and OP -AMP stations will be accessed only for routine maintenance and repair purposes. Such trips will amount to fewer than one trip per day. g. Proposed measures to reduce or control transportation impacts, if any: Installation of the fiber optic line will create only minor disruption to city streets and highways along the ROW. Any such impact will be temporary and of very short duration, because Williams Communications, Inc.

The following measures will be undertaken to minimize these temporary impacts. Please refer to the Best Management Practices in Appendix B for a detailed description of the measures to be used to reduce impacts for all disciplines. Mitigation Measure T -1: Obtain and Comply with Local and State Road Encroachment Permits. Williams will obtain all necessary local and state road encroachment permits prior to construction and will comply with the applicable conditions of approval. 15. PUBLIC SERVICES a. Will the project result in an increased need for public services (for example: fire protection, police protection, health care, schools, other)? If so, generally describe. The project will not result in an increased need for public services because the project will be unstaffed and, therefore, will not result in any population changes. b. Proposed measures to reduce or control direct impacts on public services, if any. Because there are no impacts, no measures are proposed for reducing or controlling direct impacts on public services. 16. UTILITIES a. Identify utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system, other. Single -phase power is currently available adjacent to the Cowlitz County OP -AMP station site; US West telephone service and three -phase power provided by Lewis County PUD is currently available adjacent to the Lewis County OP -AMP station site; and US West telephone service and three -phase power provided by Puget Sound Energy are available on the Pierce County OP -AMP station site. No utility services are required for the underground portions of the fiber optic line. b. Describe the utilities that are proposed for the project, the utility providing the service, and the general utility construction activities on the site or in the immediate vicinity which might be needed. Telephone and electrical services will be required of the OP -AMP station sites in Cowlitz, Lewis and Pierce Counties. The Cowlitz County OP -AMP station site will be serviced by the Kalama Telephone Company and three -phase power will be provided by the Cowlitz County PUD. Single phase power is adjacent to the site; however, Williams will tender payment to the Cowlitz County PUD to run the three -phase power to the site, which is approximately 3 miles away from the main line.

Williams Communications (Williams) proposes to install approximately 176 miles of 0 o fiber optic line from Portland, Oregon to Seattle, Washington. The fiber optic line installation is can w proposed to assist in meeting the growing demand for network capacity in the Pacific Northwest J }- and to connect existing points of presence (POP sites) in Portland and Seattle. Installation of the w p line will expand the Pacific Northwest's national telecommunications access and enhance the 2 capability and reliability of the region's telecommunication infrastructure. a Construction is proposed to begin in June 2000, after receipt of the necessary W' authorizations from the applicable governing agencies. Construction is expected to take z i. approximately 6 months. Construction on some segments of the project ROW will be subject to z o various wildlife and fisheries avoidance windows so that potential disturbance of sensitive w w species can be avoided. Testing will occur in December 2000 with commercial operation m o. scheduled to begin January 1, 2001. : p O I- ww • U ROUTE DESCRIPTION u'— . o' z A detailed description of the route, divided into three laterals, is presented below. v o 1-. z Portland Pipeline Lateral • Start at the City of Portland POP site located at 707 SW Washington Street • Leave POP site from northwest corner of the building at SW Stark Street and SW Park Avenue • Start on south side of Stark Street and angle to north side of Stark Street to intersection of Stark Street and NW 9th Avenue • Right on NW 9th Avenue • Left on NW Front Avenue (also called NW Naito Parkway) • Right at Fremont Bridge (also Highway 30 and Interstate 405) across the Willamette River (drill upstream of the bridge) • Exit drill between Loring Street and Union Pacific Railroad (UPRR) tracks • Left on Nesmith Avenue to North River Street • Right on North River Street • Take North River Street to UPRR tracks along the Willamette River • Follow the UPRR tracks to North Lombard Street • Left on North Lombard Street Williams Communications, Inc.

This results in fewer environmental impacts than installing the fiber optic line along a non - previously disturbed route 0 o because the corridors have already been disturbed and are often actively maintained. These co ° pre - existing cleared corridors are also likely to have established access for vehicles and cu I construction equipment. co o w Routes in road rights -of -way can also provide for future expansion if additional conduit is g installed. However, routes in road rights -of -way do have a higher potential for future damage to the fiber optic line and are at a further disadvantage of requiring workaround traffic operations. = c5 Installation within road rights -of -way is also less secure due to the typically high number of 1- _ other utilities within the right -of -way. z ~ 1--o z 1— uj In some cases, the conduit and fiber optic line may be installed in the roadbed to avoid 2 D sensitive resources in the road shoulder or right -of -way margins. However, this technique will v not be possible in very narrow roadbeds such as those installed on extremely steep slopes. o ; Bridge attachments will be used at some stream crossings. w v. ~ E Approximately 110 miles of the proposed fiber optic line will be installed within the ' z existing Williams Pipeline (formerly Northwest Pipeline Corporations) right -of -way (ROW) Cu easement (see the route map). The majority of the remaining line will be installed within already - disturbed rights -of -way. Optical amplification (OP -AMP) stations and short sections of the fiber z optic line will be installed outside these already disturbed rights -of -way. The project crosses mostly private land and small amounts of publicly owned land. In addition, it will cross approximately 225 streams /rivers and 400 wetlands. The route will avoid 8 archeological resource sites and pass near approximately 40 historic structures. The numerous jurisdictions crossed will require approvals and permits from various federal, state, and local agencies. These permits address a variety of resource concerns, including water quality, wetlands, wildlife, fisheries, and land use. The Washington Department of Ecology is the lead agency for the State Environmental Policy Act (SEPA) process. The only jurisdiction it crosses in Oregon is the City of Portland. The Washington jurisdictions include the Port of Vancouver, the Cities of Vancouver, Castle Rock, Edgewood, Puyallup, Federal Way, Kent, SeaTac, Tukwila, and Seattle. The counties are Clark, Cowlitz, Lewis, Thurston, Pierce, and King. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -4 Portland to Seattle Proflct Description March 2000 FACILITIES Overview The fiber optic line will consist of belowground and aboveground components. The belowground facilities are the fiber optic line, conduit, and manholes/handholes. The aboveground facilities are the line marker posts and OP -AMP stations. Fiber optic line, which is made up of bundled glass optical fibers wrapped in thin plastic sheathing, is inserted into the flexible, high- density polyethylene conduit. The conduit will have an outside diameter of 1.25 to 1.5 inches. The Portland and Seattle Laterals will consist of 6 to 20 conduits, while the Pipeline Lateral will have 6 to 9. Each conduit will accommodate one fiber optic line, which measures approximately 0.85 inch in diameter and is composed of 96 to 288 hair -thin glass fibers. . Manholes and handholes are usually placed at intervals of 3 to 5 miles to serve as splice points and assist fiber optic line installation and maintenance. The fiber optic line is installed by using compressed air to blow it through the conduit. The handholes measure approximately 30 inches wide by 48 inches long and 24 inches tall, and will typically be buried 24 inches below grade. Generally, road shoulders or other easily accessible areas are the preferable locations for handholes. In some areas, at streets or OP -AMP stations, manholes measuring 6 feet wide by 4 feet tall may be installed. Only the manhole lids, which measure approximately 36 inches in diameter, will be visible at the surface and will be at grade. Manholes are typically used when the line is installed under city streets or other urban/developed areas. Placement of the handholes and manholes along the routes will avoid sensitive biological, archeological, and geological resources. Line marker posts will be located at approximately 700- to 1,000 -foot intervals to alert people of the presence of the fiber optic line. The posts are typically 3.5- inch - diameter round PVC posts with embossed lettering 4 feet aboveground. The proposed fiber optic line includes three OP -AMP stations, each of which will be located approximately every 44 miles along the route, and sited to avoid sensitive resources. An OP -AMP station boosts the signal. OP -AMP Stations The three stations will be placed on either 2.24 acre or 5 acre sites. Stations will consist of three to eight 12- by 30 -foot precast concrete buildings on concrete pads. The concrete pads, including concrete stoops, will cover approximately 3,850 square feet. The maximum height will be approximately 11 feet. Each building is shipped from the manufacturer equipped with one or two heating, ventilation, and air conditioning units to maintain a steady temperature for the electronic equipment housed inside the station. The unstaffed, locked facility will require commercial electric power and telephone service. Periodic maintenance will occur to assure that the facility is operating properly. A diesel - powered generator (maximum 255- horsepower) and Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -5 Portland to Seattle Project Description March 2000 aboveground and bermed fuel tank will be installed for emergency back -up use. More buildings could be added if network traffic levels required it. Williams will construct the stations on or near previously disturbed sites. In addition to making construction easier, it will eliminate or minimize potential environmental impacts. Stations will not be sited in areas that: • have not been surveyed, documented, and ensured clear of sensitive biological and cultural resources by Williams' environmental consultants; • are within a designated floodplain; • are adjacent to waterbodies, including wetlands, drainages, rivers, streams, or lakes; • are on sites with known contamination; or • are in areas that are designated as scenic. Staging Areas and Access Roads Staging areas for construction equipment, materials, fuels, lubricants, and solvents will be established along the project ROW during construction to allow more efficient use and distribution of materials and equipment. Whenever possible, staging areas will be located on private lands in existing contractor yards; existing commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or level areas where grading and vegetation clearing are not required. The construction contractor, as needed, before and/or during construction typically selects staging areas. Each area is expected to be 4 to 5 acres in size. This practice is consistent with construction methods used throughout the United States. To ensure that sensitive environmental resources are adequately protected or are avoided, the locations of staging areas will be determined in consultation with environmental resource specialists. Since fuels, lubricants, and solvents will be stored on staging areas, all staging areas will be located at least 150 feet away from sensitive stream/drainages. Access to the project ROW will be by existing access roads or previously disturbed areas. While no new access roads will be created, some existing roads may require minimal repairs to make them usable for construction. After completion of the line installation, access roads will be repaired and/or improved, if necessary, to prevent future erosion. Access roads will not selected until the early stages of construction planning. Selection of access roads will be determined after consultation with qualified biologists and archeologists to ensure that sensitive environmental resources are adequately protected or avoided. Since not all of the rights -of -way follow improved roads and some areas lack bridges, construction equipment may need to be transported through some streams (i.e. Type 5 waters). In many cases, roads already cross small or ephemeral streams along the existing right -of -way to be used by Williams. In most of these instances the stream banks are gradually sloped and water flows will be nonexistent to sufficiently low to allow vehicles to drive through the channel with Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington h�4 Appendix A A -6 Portland to Seattle Projecl Description March 2000 negligible impact to the channel. In some cases, these access points may need to be modified to accommodate construction equipment by placing clean drain rock, cutting fords, or installing temporary culverts. Such modifications will be permitted through the appropriate agencies, and will not occur in streams supporting sensitive resources. z _� CONSTRUCTION 6 This section begins with a discussion of the construction management and environmental o o management response plan. Next is an explanation of the spread crews, followed by a w description of the conduit and line installation. This section concludes with a discussion of the construction of the OP -AMP stations. "- w Construction Management and Environmental Management Response Plan =w The construction management and environmental management response plan consists of z two components, personnel and training, which are discussed below. z o w moo' Personnel o cn of- A proper management structure, adequate training of field personnel, an environmental = v training program, and the ability to respond to changing circumstances are critical components to LL_ the success of the proposed fiber optic line. Training classes for the contractor and construction z crews will be held covering issues such as environmental protection, safety, spill prevention and Cu = response, fire prevention and management, and proper management of stormwater runoff. 0 1 z The field management structure will include engineering, construction, and environmental personnel such as spread superintendents, spread supervisors, contract compliance inspectors, environmental resource coordinators, and biological, archeological, and geotechnical support. The roles and responsibilities of each onsite representative will be clearly understood and communicated during the training program and are summarized below. The contractor and Williams' spread superintendents will be onsite to address engineering questions, make field decisions, and coordinate with permitting agencies. The spread superintendents have overall responsibility for onsite decisions and direct reporting responsibilities to the Williams' project manager for contract compliance. The superintendents also have the ability to shut down the construction operations in case of environmental noncompliance, emergencies, safety issues, and disputes with the construction contractor. Williams' spread supervisor will be onsite for each contractor to oversee the individual contract compliance inspectors and work with the contractor to resolve field conflicts. The spread supervisor will report directly to the construction superintendent and also perform most of the administrative duties. The spread supervisor will communicate daily all construction activities related to compliance, safety, and administration. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -7 Portland to Seattle Project Description March 2000 Contract compliance inspectors will be assigned to each construction crew to observe their work. Where crews work in the same area, one inspector could monitor more than one crew. The inspector will monitor the environmental resource concerns and check implementation of the erosion protection measures. The contract compliance inspector will be z trained on environmental issues that may be encountered during the construction project and will a have immediate access to biologists, archeologists, and geologists. . I w rt The environmental resource coordinator will work with the contract compliance inspector -J o and biologists, archeologists, geologists and agencies, and the engineering and construction co 0 representatives to resolve conflicts and coordinate resource avoidance and protection. The w = environmental resource coordinator will patrol the construction site periodically to help monitor co u_ implementation of the resource protection measures. w 0 2 Biologists, archeologists, and geologists will be onsite during construction. They will u. j ,locate and stake sensitive resources in the field, note the resources on the construction drawings, co d and advise the contractor regarding the necessary protection methods. They will also coordinate ▪ _ with monitors from the appropriate agencies. z r F- o. z I- LL! activities associated with construction will proceed as follows: 2 D ui U0 • locate all sensitive resources, construction methods, and avoidance measures or o mitigation measures on the construction drawings; w — w • acquire permits and approvals from governing agencies; �; • prepare traffic control plans, as necessary; L!- 0 • conduct preconstruction wildlife surveys in predetermined suitable habitat areas; w • stake and flag resources as stipulated in the environmental documentation and from v = 1-; o results of field surveys conducted for each project route; z • prepare the rights -of -way and install sedimentation control measures where needed; • install conduit, the fiber optic line, and associated facilities; • restore the rights -of -way and install erosion control measures; • apply seed and mulch as specified in the SWPPP and reclamation plans; • monitor erosion control; and, • monitor success of mitigation. All levels of field management and construction personnel will be informed about environmental protection and the necessity of compliance. Training will take place at the Williams engineering level and at the contractor level. Appropriate personnel from the regulatory agencies will be invited. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland. Oregon to Seattle, Washington Appendix A A -8 Portland to Seattle Proj ct Description March 2000 Training Training seminars led by project managers and resource experts will be held before construction to explain and educate construction supervisors and managers about the following: z a �. • the need for and importance of resource avoidance and protection; i Z • resource mapping format and interpretation of construction drawings; c4 2 • resource protection staking methods; 6 • the construction process as it relates to required mitigation measures; 0 o • roles and responsibilities; and, w = • the project management structure and contacts. —J F- V) w 0 All contract compliance inspectors will be required to complete an inspector training 2 class. These classes will cover issues such as the environmental issues mentioned above, g Q resource mapping and construction drawing interpretation, roles and responsibilities, and site N ,safety. The contractor team will include the job superintendent, crew foremen, and z o. crewmembers. The training and education will take place through several processes beginning at uj with the preconstruction meetings and ending with training classes just before construction D o activities begin. O o D DE- �� Meetings with the contractor will be held prior to construction and will include i v: discussions about the issues listed above. They will be used as an opportunity to reinforce the w need for and importance of compliance with environmental resource avoidance and protection . w z measures. o O~ The spread superintendents, supervisors, contract compliance inspectors, and Z environmental coordinators will conduct meetings regularly with the contractors' superintendents and foremen to coordinate the construction and mitigation processes. The contractors' foremen will be responsible for transmitting, on a weekly basis, the information discussed in the preconstruction meetings to the crewmembers. Spread Crews Discussed below are the number and types of crews associated with each spread and the flow of construction activities along the project ROWs. The actual number and composition of the workforces may vary with conditions at the time of construction. The contractor is responsible for determining the most efficient methods for completing the work within the parameters given. Before beginning construction, Williams and the onsite biological monitor will review the rights -of -way to determine the most appropriate access method for each stream and will note these methods on the construction drawings. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -9 Portland to Seattle Protect Description March 2000 Williams anticipates hiring multiple contractors depending on the amount of time available to install the conduit and line and construct associated facilities. Each spread will consist of the following 6- to 12- person crews: • Preparation Crew - The preparation crews will prepare the right -of -way for z construction by placing temporary gates in fences, clearing vegetation where ' 1 z necessary, and repairing erosion problems on existing roads to provide access. ce 2 • Conduit and Line Installation Crew - The conduit and line installation crews will 6 = install the conduit and line. 0 0 i 0 • OP -AMP Station Crew - The OP -AMP station crew will prepare the site and vi w construct the stations. • Cleanup Crew - The cleanup crews will perform final cleanup of the right -of -way, w 0 w restoring preinstallation ground contours, installing erosion protection measures (e.g., 2 erosion control blankets), restoring affected stream channels and removing fences and g Q gates. Clean up will be ongoing and will take place immediately after all work is co 0 completed per segment. rz- W • Seeding Crew - The seeding crews will apply seed and mulch where necessary. z F- 0 z1-- Conduit and Fiber Optic Line Installation • 0 0 Conduit and line installation will not threaten overhead utilities due to the amount of O 1-: vertical clearance under the utilities. For underground facilities, the "One Call" utility location z cw.s. services will be contacted a minimum of 48 hours before construction. The "One Call" services „ o will alert all registered utilities about the scheduled construction activities, allowing the utilities z to identify the location of their underground facilities and thus greatly reduce the possibility of 0 =. interruptions in utility services. 01- In many instances, the project will cross private property. Landowners, with whom easements will have already been obtained, will be contacted before construction. Right -of -way personnel will be available to answer landowners' questions and to negotiate any cleanup or restoration issues that may arise. Williams will negotiate with the owners and tenants regarding any project - related crop losses. The timing of construction will, wherever practicable, be during idle field time. Any trenching activities in farmland will be done according to the above - mentioned procedures. Three methods will be used to bury the conduit, based on several factors, including site conditions. The methods of plowing, trenching, and drilling are described below. Plowing installation uses a Cat with a cable reel in front and a plow blade in back (See typical(s)). As the Cat moves, it simultaneously furrows the soil and installs the conduit. The plowing Cat weighs approximately 43 tons. The plow furrow will typically be one foot wide and 48 inches deep. In some instances, the soil may be pre -ripped by a tractor in front of the plow. Ripping is a technique in which a slit is made in the surface of the soil to loosen it. The construction corridor is usually up to 30 feet wide. Up to 2 miles of plowing can be completed per spread, per day. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -10 Portland to Seattle Profict Description March 2000 z Trenched installations will predominantly be used at tie -in points to connect conduit at handholes and manholes. The trenches will be 4 to 6 feet wide, 8 to 10 feet long, and 48 inches deep. Other narrow trenching will be done in certain metropolitan areas where drilling or plowing is not feasible. Trenching is typically done with a rubber -tired backhoe or an excavator, using an 18- to 24 -inch bucket. A backhoe weighs approximately 8 tons. If conditions do not allow for small isolated areas, such as handholes or assist points, to be backfilled at the end of each day, appropriate safety, erosion, and wildlife control features will be installed. A 30 -foot wide right -of -way is needed where trenching is to take place, of which ten feet is required for tracked/rubber -tired equipment and vehicular construction traffic. The construction corridors will typically be confined to within the existing rights -of -way. Directional drilling will be used in various locations along the ROW to cross -areas where surface disturbance must be avoided (e.g., crossing railroads, highways „rivers, sensitive streams, and wetlands). Directional drill lengths could range from less than 100 feet to 750 feet. To complete the drill, a work area is established on each side of the crossing (see typical(s)). For river, stream, and wetland crossings, the work areas, will be located at distances stipulated by the local jurisdictional buffer ordinance distance from the bank or edge of the resource. One work area contains the "pilot hole” and drilling equipment. The other work area contains the "receiving hole" where the drill bit emerges. Depending on the length of the drill, the drill entry areas range from 2 feet by 2 feet to 4 feet by 4 feet. Drilling equipment most suitable for site - specific conditions will be used for each drill. Silt fences, straw bails, and other erosion control measures will be installed around these work areas. Approximately 500 feet of drilling could be completed per day, per drill rig. During the drilling process a bentonite slurry typically is pumped through the drill hole to help lubricate the drill bit, prevent the drill tunnel from collapsing, and carry drill cuttings to the surface. Bentonite is a naturally occurring clay known for its hydrophilic characteristics. The slurry is pumped through the drill hole, collected at the surface, passed through machinery to remove the drill cuttings, and then recirculated through the hole. The slurry may be stored in tanks at the drill site when not in use. Any excess slurry remaining after the drill is complete will be removed from the site and either reused by the drilling contractor or disposed of at an appropriate facility. Although highly unlikely, the drilling slurry could escape the drill hole through cracks or fissures in the soil and reach the ground surface. All efforts will be made to complete directional drills at sufficient depths to prevent bentonite releases. Drilling under roads will be at a depth of at least 5 feet, while under flowing streams, the minimum depth will be 10 feet. While plowing will be used at some stream crossings (i.e. Type 5 Streams), flowing streams with sensitive resources (e.g., high -value habitat for threatened or endangered species) will be crossed by attaching the conduit to an existing bridge or by drilling under the stream (see typical(s)). The work areas will be located outside the stream area. No in -water trenching is proposed in flowing streams with sensitive resources located at or downstream of the crossing. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington • A -11 Appendix A Portland to Seattle Project Description March 2000 The drill entry site for the Columbia River will be located on Port of Vancouver property. The exit site will be in Kelly Point Park in Portland. The work areas on each end of the drill will be approximately 100 feet wide and 300 feet long. The entry area will be a maximum of 15 feet by 15 feet and one foot deep. The drill will be approximately 4,300 feet long. The conduits, which will be in a 10 -inch steel casing, will be at least 20 feet below the river bottom. The drilling operation will take approximately two weeks. After completion of the drilling, the work areas will be refilled with the same material taken out and the work area will be restored to its pre - construction condition. OP -AMP Stations The following is a description of the construction process of the OP -AMP stations: • grade site level; • fence off the site; • hook -up electrical service; • gravel site; • install concrete pads; • place precast buildings on pads; and, • install electronic equipment, and other appurtenances. OPERATIONS Operation activities will consist of maintaining erosion control measures, repairing or replacing line conduit due to of storm damage or other emergencies, and routine maintenance of the OP -AMP stations. In most emergency situations, access to inspect damaged areas will be accomplished via helicopter or public roads. After installation, access for maintenance will also be by existing access roads to the right -of -way. MITIGATION Williams will be responsible for implementing the mitigation measures identified in this document and other measures that will be determined by the associated permitting agencies and through the permitting process. The general mitigation measures that are known at the time of the preparation of this document are described below. The measures have been developed and designed as part of the proposed fiber optic line to avoid or reduce potential significant impacts to less - than- significant levels. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -12 Portland to Seattle Project Description March 2000 • i1 Avoidance Measures Sensitive resources will be avoided through various means identified during the project design phase. However, there also will be avoidance measures occurring in the field during construction as a result of preconstruction surveys or at the direction of construction inspectors. If required, the construction technique will be coordinated through a monitoring resource specialist familiar with the resource issue being avoided. Typical avoidance measures include minor rerouting of the cable around the sensitive resource within the disturbed right -of -way, drilling under the resource, or attaching the line to an existing bridge. Significant impacts will be avoided at sensitive drainages, including perennial stream crossings or streams that are flowing at the time of construction and have sensitive resources located at or downstream of the crossing. At all streams that provide important habitat, contribute significantly to water quality, or support sensitive or listed aquatic species, conduit and the fiber optic line will be installed either by drilling under the drainage or by attaching the .line to existing bridges. In many situations, these methods will also be used for wetlands. The avoidance methods for each sensitive resource will be shown on the construction drawings. Best Management Practices Best management practices detailed in the Stormwater Pollution Prevention Plan (SWPPP) will be implemented. Spill prevention countermeasures contained in the SWPPP (required under the NPDES permit) are designed to prevent or minimize the risk of bentonite entering surface waters during directional drilling. Although bentonite releases rarely occur, bentonite can reach the ground surface and enter surface waters if the drill encounters a rock fracture during high- pressure drilling operations conducted over long distances. However, the risk of bentonite reaching the surface or surface waters is minimized because contractors typically use the smallest practicable drilling equipment which injects the bentonite at lower pressures. Erosion is the process of soil particles being displaced and transported by wind or water. Conduit and fiber optic line installation will disturb soil and vegetation, exposing sites to possible erosion. The hazard of erosion is increased by the presence of steep slopes, concentrated or channelized water flow, and high streamflows. The best management practices that will be undertaken in accordance with all applicable regulations and standards will be implemented by Williams' contractor as specified in the SWPPP that will be prepared for the project. Erosion and sediment control measures are used to reduce the amount of soil that is carried off a land area, and to control the discharge of soil particles that are carried away. The following standard erosion and sediment control measures and practices will be used during and after construction to control accelerated soil erosion and sedimentation. • minimize site disturbance; Williams Communications, Inc.

The most basic way to avoid erosion is to minimize site disturbance. Williams' contractors will be directed at the environmental training program to implement practices that minimize site disturbance to ensure impacts are avoided or reduced to less - than- significant Tevels. These measures (described below) are routinely implemented in the construction industry and have been proven successful for similar buried telecommunication system installations. The contractors will be directed to: • remove only the vegetation that is absolutely necessary to remove; • avoid off -road vehicle use; • avoid all sensitive resource areas; • avoid excessive trips along the right -of -way or access or maintenance roads; and, • instruct all personnel of the concepts of stormwater pollution prevention to ensure that all are conscious of how their actions affect the potential for erosion and sedimentation. Williams' inspectors will be onsite during all construction activities and will reinforce the importance of confining all vehicular traffic to the existing right -of -way and maintenance and access roads. Williams' contractors will be directed to perform initial site cleanup immediately following conduit and fiber optic line installation. Initial cleanup includes removing debris and spoils and restoring original contours. Initial cleanup performed as part of the construction will contribute significantly to the overall site stability and will make final cleanup easier. The site will immediately begin to stabilize naturally with little additional disturbance during final cleanup. A site that is not initially cleaned up is more susceptible to erosion. Proper compaction of subsurface soil serves as an erosion control measure. Uncompacted plow or trench furrows are susceptible to subsurface erosion through the migration of surface and subsurface water. Proper compaction of the subsurface material and plow furrows is necessary to help prevent surface and subsurface migration of water along the plow or trench furrow and to prevent trench settlement. The reapplied topsoil in the right -of -way will be left in roughened condition to facilitate the establishment of vegetation and reduce the potential for erosion. Williams Communications, Inc.

Trench plugs serve to control erosion by stopping subsurface water flow. Trench plugs are placed in the trench at regular intervals along areas with steep slopes. The spacing is determined by slope grade, topography, and soil characteristics. Trench plugs will be installed as shown on the construction drawings. �z w Seeding consists of sowing soil - stabilizing grasses on areas disturbed by construction activities except cropland and areas surfaced with pavement or gravel. Vegetation serves both _ o erosion and sedimentation control. The root structure of the vegetation holds soil in place to co o: resist erosion. Grasses slow the flow of surface water, allowing suspended particles to settle. J I Mulch, typically consisting of wheat straw, is usually applied over the seed to protect the soil CO a_ surface until the grasses become established. ui I!. Q Steep Slopes = Iw On steep slopes that are susceptible to erosion, erosion control blankets will be installed z to hold seed and soil in place until vegetation is established. The onsite- spread supervisors will w o uj determine where blankets are necessary. g U� Silt fences and straw bale dikes will be installed, as needed, at the toe of slopes below o D` disturbed areas to prevent sediment from reaching streams and wetlands. These sediment w w barriers retain sediment while allowing water to seep through. Straw bale dikes may also be _- installed around drop inlets and in small swales to retain sediment. 0 U ( Water bars are an erosion control measure that function by slowing runoff rates and 1 diverging runoff from the disturbed area. A water bar consists of an earthen berm placed along z the ground across the disturbed area of construction. Water bars are left in place and become permanent erosion control measures. A baffle board is an erosion control measure consisting of pressure - treated 2- by 12 -foot boards and 4- inch - diameter wooden posts. Baffle boards work like water bars but are used on slopes too steep for water bars. However, baffle boards cannot be used on roads. Board spacing is determined by slope grade, topography, and soil type. The contractor will install baffle boards, as necessary, during the final cleanup stage of installation. Riprap is an established method of permanent erosion control. Riprap will be used for slope stabilization, water energy dissipation, and armoring of stream banks. Riprap will be used only on stream banks where the existing channel consists of rock or in highly erodible drainages that lack woody riparian vegetation. Armoring drainage banks with riprap may be used on rare occasions. Permanent erosion control measures are currently in place along much of the existing right -of -way as a result of previous facility construction. The effectiveness of these measures will be evaluated before construction. Any existing measures will be restored, as required and Williams Communications, Inc.

The spread superintendent following construction activities to determine where additional erosion control measures are necessary will also assess the right -of -way. Reclamation z Right -of -way reclamation is the final step in the installation process. The short-term 6 objectives of reclamation are to control accelerated erosion and sedimentation, and to minimize v o impacts on adjacent waters, land uses, and other sensitive resources.

The reclamation effort will focus on the following uj 0 objectives: D- u_ j. ' • topsoil salvage, storage, and replacement; cn et • reclamation of right -of -way and associated maintenance and access roads; _ • reclamation of drainage and wetland crossings; and, z o • monitoring to ensure long -term success. Z I- LL! �o In most instances, access and maintenance roads were constructed when the original o utility, pipeline, or railroad facilities were constructed. These existing roads provide access to o SP- the rights -of -way from other public or private roads. Minimal grading of these roads may be w w necessary in isolated areas to prepare them for use during construction. v. u- ~O In addition to paved state and county roads, the access and maintenance roads may also id include improved and low -use unimproved secondary roads. Following construction, the right- 1 _`. of -way or disturbed areas will be graded to preinstallation grades and contours. Little grading is z ~ expected because no excavation activities will occur on the roads except to correct existing erosion problems. The following soil handling methods will be implemented to promote successful restoration: • any refuse and debris will be removed from the compacted trench or excavation before topsoil is replaced, and • the length of time topsoil is stored will be minimized based upon the pace of the installation activities (normally, topsoil removal and respreading activities will occur on the same day). When the crossing is completed, the beds and banks of the drainages will be restored in a manner that allows vegetation to reestablish to its preinstallation conditions. Where necessary, a biodegradable erosion control blanket or riprap will be used to protect and stabilize streambanks. Riprap will be used only where existing stream channels consist of rock armoring and lack woody riparian vegetation. Erosion control blankets will be used on steep slopes or where the Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix A A -16 Portland to Seattle Project Description March 2000 Th soils otherwise have a high erosion potential. The type and locations for these measures will be determined in the field by the spread supervisor with input by other appropriate personnel.

Any fluids drained from the machinery during servicing will be collected in leak -proof containers and taken to an appropriate disposal or recycling facility. If these activities result in damage to or accumulation of a product on the soil, it will be assessed and disposed of properly. Under no circumstances will knowingly contaminated soils be added to a spoils pile. Mobile refueling trucks will do onsite refueling of construction equipment. The refueling trucks will be independently licensed and regulated to haul and dispense fuels. This licensing and regulation will ensure that the appropriate spill prevention techniques are implemented. Restrictions will be placed on all equipment refueling, servicing, and maintenance supplies and activities. All maintenance materials, oils, grease, lubricants, antifreeze, and similar materials will be stored offsite in staging areas.

During construction, all vehicles and equipment required onsite will be parked or stored at distances stipulated by the local jurisdictional ordinance so as not to affect rivers, streams, wetlands, known archeological sites, and other sensitive resource areas. These areas will be identified on the ground and noted on appropriate maps and construction drawings. All vehicle and equipment wash down activities will be conducted at the staging areas. Fire Prevention Fire prevention and response plans will be submitted to the appropriate regulatory agencies for some routes, as required by applicable regulatory agencies. The plans will be developed with input from the fire response managers of affected agencies, and will be completed prior to construction of the applicable route. The plans will identify the fire precaution and suppression measures that will be implemented, and the parties responsible for fire prevention and response. Prevention and response measures, such as requirements to have firefighting water tanks onsite and extinguishers and shovels in vehicles, will be identified. Williams Communications, Inc.

Waterbars shall begin and end in undisturbed vegetation or soil. Woody material (such as low shrubs) will not be removed, but rather placed back on the ROW with topsoil to provide a seed source and organic matter. • Other measures to restore or improve surface drainage measures already existing on the right of way might include tightlining discharge from water bars and diverting or collecting surface water coming on to the right -of -way and tightlining on the onflow to below the slope. • Where sediment could be transported onto a public road surface or other paved area by equipment or vehicles accessing or leaving the construction site, sediment will be removed from the road immediately by shoveling or sweeping and transported to a sediment - controlled disposal area. • Inspections of site conditions and the BMPs will be conducted prior to anticipated storm events to identify areas that may contribute to sediment discharge; corrective actions will be made as required. • All erosion and sediment control measures will be checked within 24 hours of each 0.5 -inch or greater rainfall event and every 14 calendar days during October 15 through April 15, up until the time that site stabilization is achieved. During April 16 through October 14, the inspections will be conducted every 30 days. During extended storm events, inspections will be conducted at least once every 24 hours. • Inspection reports will be completed after each inspection and included in the project file. Ineffective temporary erosion control measures will be repaired or replaced as soon as possible but no later than 24 hours after identification. • Williams will retain completed inspection forms for at least 3 years. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. Williams Communications, Inc.

If the side slope cut is longer than 200 feet, an erosion control blanket will be used with reseeding. The cut slope will not exceed 1.5:1, and the fill slope will not exceed 2:1. • Any soil stockpiled next to trenches that are subject to erosion will either be located on the upslope side of the trench, protected using straw bale dikes or silt fences, or covered with plastic, as appropriate. • The contractor must have on hand a minimum of eight straw bales at all times for emergency sediment containment purposes. • Repair existing roads upon completion if additional disturbance is created from fiber optic line installation construction activities. • Installation of steel casing will require standard cut -and -cover trenching techniques. Trenches should be backfilled with select backfill and compacted. Trench plugs should be installed periodically within the trench to prevent piping of the backfill and to limit Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix 13 13-4 Best Management Practices March 2000 groundwater movements. Water trapped at the trench plugs should be captured in a French drain and tightlined below the right -of -way and off the potential landslide area. • In some landslide areas it may be possible to span the affected area by stringing the fiber optic conduit and line aboveground on poles. Poles within the landslide mass may also be feasible where the landslide plane is below the depth of embedment of the pole, z allowing the pole to move with the landslide mass. . = z re 111 • Site visits should be performed for all active and potentially active landslide areas.

These parties will be notified within 24 hours of an accidental find. • Specific OAHP instructions concerning an accidental find resulting from the notification(s) described above will be followed on a case -by -case basis. At a minimum, sufficient archaeological work will be performed on the accidental find location to stabilize deposits, protect deposits from scavengers or looters, and to collect readily available samples (e.g., for radiocarbon dating) which may help pinpoint the age of deposits or, in the case of burials, the presence of data which may serve to identify lineal or cultural descendants. • The owner and its cultural resources consultant will consult with OAHP to follow through on the course of action selection to comply with Section 106. This may require development of an MOA or implementation of actions involving the find that satisfy Section 106, and may involve consultation with Native American groups. In any case, Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington Appendix 11 B -5 Best Management Practices March 2000 construction will remain halted in the immediate area of the accidental find until OAHP indicates in writing that the undertaking may proceed in the area. • In the case of an accidental find of human remains, all relevant recommendations (e.g., NAGPRA legislation) regarding treatment of such remains will be followed. The owner recognizes the importance of providing careful and respectful treatment of human remains recovered as an accidental find or as part of an archaeological investigation. If - z the proposed undertaking is not on Federal or Native American lands, consultation prior ce 2 to implementation is not required. In the event of an accidental find of human remains, 0 v the owner will contact OAHP for appropriate Native American groups with which to N 0 consult.

Washing will be conducted in a manner that avoids runoff from the washing area. • Where paved surface restoration requires the use of concrete, a concrete washout will be used to rinse or clean tools. The securely anchored washout, constructed using a straw bale perimeter and plastic sheeting ground cover, will be adequately sized to contain all material washed into it. Following the completion of activities requiring concrete resurfacing, all contents contained in the washout will be properly disposed of offsite. • Spills will be documented and a record of the spills will be kept with the SWPPP. If a spill occurs that is reportable to the federal, state, or local agencies, the resource monitor is responsible for the reports. • All waste material will be collected and stored in a secure container and removed from the project ROW. The waste container will be inspected regularly and the contents will be disposed of properly by the owner. No waste oil or other petroleum -based products will be disposed of onsite (e.g., buried, poured), but will be removed offsite for proper Williams Communications, Inc.

Earth spoiled by J = drilling slurry will be removed and disposed of by the contractor, and the ROW will be w refilled with clean material. Upon completion of construction, the ROW will be restored u to a condition equal to or better than its original condition. a =w _ z� • All steep, unstable slopes will be left vegetated whenever possible. z o. w • Compaction and grading of soils close to mature trees should be avoided to prevent 2 o U O -` 01— • Limited removal and disposal of trees and/or brush within the construction zone and as w w per engineering drawings and typicals is expected. If required, a subcontractor will cut brush and trees as needed to create a clean path up to 10 feet wide for construction u. 0 equipment access. Where this is needed, all trees and shrubs will be cut flush with the o cn ground (existing ground). Some downed trees may be left on site to provide habitat for o small mammals, birds and insects and to provide nutrient cycling processes. Smaller z limbs and brush may be chipped to aid erosion control and to reduce fire hazard. • Mixing of topsoil with subsoil will be prevented by using topsoil segregation methods. When implementing these methods, topsoil will be windrowed separately from subsoil. Topsoil will be stripped from the subsoil storage area and stored along the edges of the corridor with other stockpiled topsoil. For deep soils (that is, in floodplain and stream terraces), at least 12 inches of topsoil will be segregated. Where soils are shallow to bedrock or have stony subsoil, all available topsoil will be separated from coarser parent material. • VEGETATION damage to root systems. • Topsoil and other suitable growing media will be used to restore suitable plant growing conditions after construction is completed. • Final stabilization for the purpose of terminating coverage under the general permit is achieved when all soil - disturbing activities are completed and either (1) a uniform vegetative cover of 70% has been established or (2) equivalent stabilization measures (e.g., erosion control blankets) have been installed. • All groundbreaking disturbances will be seeded with native species for erosion control. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington 01679- eTKfAM B -7 Appendix B [lest Manag✓7nent Practices March 2000 • Seeding or mulching will be done only in those portions of the right -of -way that were vegetated prior to the start of construction. Seeding or mulching will be conducted if construction halts for more than 21 days during the rainy season (i.e., October 15 through April 15). WATER QUALITY • Soil disturbances on slopes of more than 40% will be avoided as much as possible. • The use of biodegradable matting will be used only in areas of steep slopes that are near critical areas (e.g., streams). • Topsoil will be preserved and replaced to the greatest extent possible to maximize the effectiveness of revegetation efforts. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid substantial soil loss and displacement. • Where fertilizers are used, they will be applied only in the recommended amounts. Once applied, the fertilizer will be worked into the soil to limit exposure to storm water. Fertilizer spills will be cleaned up immediately. • Watering trucks or other appropriate dust - abatement measures will be used to control dust generated during construction as required to prevent fugitive dust emissions. Applying water to the point that runoff occurs will be avoided. WETLANDS • Identify sources of sediment and other pollutants that can affect the quality of storm water discharges. • Under no conditions will soil or other material be intentionally washed into storm drainage systems, drainages, or wetlands. • Focus on controlling erosion rather than controlling sedimentation. Williams Communications, Inc.

I. Construction Management Structure A. Organization Williams Communications has established a field management structure for this project that will include engineering, construction, and environmental personnel such as Spread Superintendents, Spread Supervisors, Contract Compliance Inspectors, Environmental Resource Coordinators, Environmental Resource Monitors, and biological, archaeological, and geotechnical support (see attached - Figure 1). The roles and responsibilities for all onsite personnel will be clearly understood and effectively communicated through the training program. Responsibilities for field personnel will include, the ability to issue a stop work order for the project should permit conditions be violated, or if the work constitutes a significant environmental hazard that leads to noncompliance. Williams Communications will use Jones & Stokes of Bellevue, Washington and/or other third party monitors to ensure environmental compliance. B. Roles and Responsibilities Williams Spread Superintendent The contractor and Williams' Spread Superintendent will be onsite to address engineering questions, make field decisions, and coordinate with permitting agencies. The Spread Superintendents have the overall responsibility for onsite decisions and direct reporting responsibilities to the Williams' project manager for contract compliance. The superintendents also have the ability to shut down the construction operations in case of environmental noncompliance, emergencies, safety issues, and disputes with the construction contractor. Williams Compliance Plan O6/08/OO 1 Williams Spread Supervisor Williams' Spread Supervisor will be onsite for each contractor to oversee the individual Contract Compliance Inspectors and work with the contractor to resolve field conflicts. The Spread Supervisor will report directly to the Spread Superintendent and will also perform most of the administrative duties. The Spread Supervisor will communicate daily all construction activities related to compliance, safety, and administration. ce 6 Contract Compliance Inspectors v o cn The Lead Contract Compliance Inspectors will supervise the Contract Compliance Inspectors. Contract Compliance Inspectors will be assigned to each construction crew to w wO observe their work and shall have the authority to stop work on the project. Where crews work in the same area, one inspector could monitor more than one crew. The inspector will monitor the environmental resource concerns and check implementation of the c erosion protection measures. The Contract Compliance Inspector will be trained on w environmental issues that may be encountered during the construction project and will z �. have immediate access to Environmental Monitors (e.g. biologists, archeologists, and z o geologists). w w U° ,O tA. Environmental Resource Coordinator ° w w:. The Environmental Resource Coordinator will work with the contract compliance u. o inspector and biologists, archeologists, geologists and agencies, and the engineering and w construction representatives to resolve conflicts and coordinate resource avoidance and protection. The Environmental Resource Coordinator will patrol the construction site p (- periodically to help monitor implementation of the resource protection measures. z Environmental Monitors The Environmental Monitors will be assigned to each construction spread to ensure compliance and enforce the provisions of all conditions and stipulations of the permits issued for construction. Environmental Monitors will have the authority to stop work on the project if necessary. A Lead Environmental Monitor working in direct association with the Environmental Resource Coordinator will manage and provide oversight for the Environmental Monitors working in the field. The Environmental Monitors locate and stake sensitive resources in the field, note the resources on the construction drawings, and advise the contractor regarding necessary protection methods. They will also coordinate with monitors from the appropriate agencies. All levels of field management and construction personnel will be informed about environmental protection and the necessity of compliance. Training will take place at the Williams engineering level and at the contractor level. Appropriate personnel from the regulatory agencies will be invited. Williams Compliance Plan 06 /08 /00 Environmental Monitors shall have at a minimum a bachelor's degree in a related environmental discipline and sufficient experience and expertise for the responsibilities of the position. As needed, additional Environmental Monitors will be assigned to the project. z i �. II. Construction Compliance Program re 6 A. Environmental Training and Awareness 0 co a 0 cnw Training seminars led by project managers and resource experts will be held before N construction to explain and educate construction supervisors and managers about the w o. following: 2 • the need for and importance of resource avoidance and protection; j. • resource mapping format and interpretation of construction drawings; = cg • resource protection staking methods; u Z • the construction process as it relates to required mitigation measures; o • roles and responsibilities; and, w • the project management structure and contacts. ? All contract compliance inspectors will be required to complete an inspector training o t2—. class. These classes will cover issues such as the environmental issues mentioned above, resource mapping and construction drawing interpretation, roles and responsibilities, and ▪ 0 site safety. p. .z Cu �. The contractor team will include the job superintendent, crew foremen, and v = crewmembers. The training and education will take place through several processes z beginning with the preconstruction meetings and ending with training classes just before construction activities begin. B. Compliance Process Prior to the commencement of work, the Environmental Resource Coordinator and Environmental Monitors will conduct an inspection of the project running line to determine those areas where special protective measures or construction techniques will need to be employed. Those areas of concern requiring special measures or techniques will be marked in the field using flagging, stakes, poles, paint, or any other method deemed appropriate and necessary to properly delineate sensitive resource. The Environmental Monitor and Contract Compliance Inspector will review areas of concern prior to the commencement of construction and conduct weekly assessments during active construction. The Environmental Monitor will be onsite while construction is ongoing to monitor the contractor's work and answer any questions relating to environmental compliance. Environmental Monitors and Contract Compliance Inspectors will have in their possession the State Environmental Policy Act checklist and Williams Compliance Plan owolvoo 3 Ii n,;1r9L• 2(C,- 1�Ciihly{ E!Re. ms copies of regulations and permit conditions applicable to environmental compliance for the project. C. Construction Compliance Meetings Meetings with the contractor will be held prior to construction and will include discussions about the issues listed above. They will be used as an opportunity to reinforce the need for and importance of compliance with environmental resource avoidance and protection measures. The Spread Superintendents, Spread Supervisors, Contract Compliance Inspectors, and Environmental Coordinators will conduct meetings regularly with the contractors' superintendents and foremen to coordinate the construction and mitigation processes. The contractors' foremen will be responsible for transmitting, on a weekly basis, the information discussed in the preconstruction meetings to the crewmembers. D. Bonding The construction contractor will be required to post a performance bond with Williams Communications as a condition of the construction contract. The purpose of the bond is to ensure that all provisions of the contract, including adherence to engineering design and construction specifications, environmental compliance, and performance of the work will take place as specified in the contract. Williams Communications reserves the right to withhold the bond or any portion thereof should the contractor fail to perform. Williams Compliance Plan 06/08/00 BEST MANAGEMENT PRACTICES The following best management practices will be implemented as mitigation for this project: Wiz. A. Air cc U J U. • Watering or other appropriate dust - abatement measures will be used to control u) 0 fugitive dust generated during construction. J i u) u.. • Vehicles and equipment used during construction will be properly maintained to w o minimize exhaust emissions. 2�. a B. Aquatic Resources Y d. _ z1 • The limited brush clearing of stream banks will take place immediately prior to z o fiber optic line installation to minimize the exposure of bare soil. M D D O' • Stream bank and floodplain stabilization measures will be implemented o immediately prior to and maintained during and after construction. w w` H • U' • Stream crossings will be avoided at a stream bend, in areas of undercut banks, or u. o in areas where the bank is unstable. ui U S. • Uprooting of woody vegetation will be avoided to the greatest extent possible on p 1--' stream banks by minor rerouting of the fiber optic line route location, or by z clearing vegetation using equipment, which leaves the root system intact (e.g., chain saw or brush hog). • All grading will be performed in such a way as to minimize the introduction of sediments into streams. • Prevent a net increase of sediment discharge by using and maintaining temporary sediment control measures. • No artificial flow obstructions will be left in the streambed or channel. • The strcambed and banks will be restored to stable contours, if necessary, to allow the establishment of vegetation. • The native vegetation must be established within one year after project completion in wetland areas where land clearing is necessary for construction access. • All handholes will be located outside of streambeds and banks. Williams Compliance Plan OG/ORIOO 5 • All work areas for stream crossings will be kept at least 200 feet away from the stream. • No refueling, or servicing will be done within a stream buffer. Absorbent material or drip pans will be placed underneath the equipment to contain leaks or z spills. 4i Z • A Storm Water Pollution Prevention Plan (SWPPP) will be completed and filed Q: m with appropriate agencies prior to any construction activities. o co o • Williams must maintain a copy of this SWPPP onsite from the date of project J initiation to the termination of coverage under the general permit. co LL_ . w o. • All contractors and subcontractors must provide contact and responsibility 2 information and sign a copy of the certification form found at the end of this g a. section before conducting any professional service at the site identified in the a SWPPP. 1- _ z1 • The signed certification statements will be kept with the SWPPP and will serve as z o an official record of all contractors and subcontractors and their responsibilities in w implementing the SWPPP. v 0 22 • Construction of stream crossings will be done in accordance with applicable w w timing restrictions based on the classification of the waterway and the appropriate = 0 regulations. I'_- p' .z. • Identify sources of sediment and other pollutants that can affect the quality of U o I-- storm water discharges. • Under no conditions will soil or other material be intentionally washed into storm drainage systems, drainages, or wetlands. • Focus on controlling erosion rather than controlling sedimentation. C. Fish and Wildlife • Revegetation will occur as soon as possible to minimize changes to these fish and wildlife species habitat as well as minimize corridor fragmentation. D. Floodplains • Construction activities and permanent placement of the conduit, fiber optic line, handholes, OP -AMP stations, and all other project features will not increase flood heights or flood inundation boundaries within floodplains. • Construction staging areas will not be located within floodplains. Williams Compliance flan 0W08 /00 - 6 - Vale z • All materials such as the conduit, fiber optic line, and handholes will be buried, and thus anchored to prevent flotation, collapse, or lateral movement of the structure. E. Geology and Soils • Surface reclamation will involve the clearing of construction debris from the right -of -way (ROW) to leave the soil in the proper condition for planting, ensuring clearing of all construction debris and woody material. • On slopes, surface flow will be diverted by waterbars to a stabilized outlet using runoff diversions with a 2% outslope directed toward appropriate energy - dissipating structures. Waterbars shall begin and end in undisturbed vegetation or soil. Woody material (such as low shrubs) will not be removed, but rather placed back on the ROW with topsoil to provide a seed source and organic matter. • Other measures to restore or improve surface drainage measures already existing on the right of way might include tightlining discharge from water bars and diverting or collecting surface water coming on to the right -of -way and tightlining on the onflow to below the slope. • Where sediment could be transported onto a public road surface or other paved area by equipment or vehicles accessing or leaving the construction site, sediment will be removed from the road immediately by shoveling or sweeping and transported to a sediment - controlled disposal area. • Inspections of site conditions and the BMPs will be conducted prior to anticipated storm events to identify areas that may contribute to sediment discharge; corrective actions will be made as required. • All erosion and sediment control measures will be checked within 24 hours of each 0.5 -inch or greater rainfall event and every 14 calendar days during October 15 through April 15, up until the time that site stabilization is achieved. During April 16 through October 14, the inspections will be conducted every 30 days. During extended storm events, inspections will be conducted at least once every 24 hours. • Inspection reports will be completed after each inspection and included in the project file. Ineffective temporary erosion control measures will be repaired or replaced as soon as possible but no later than 24 hours after identification. • Williams will retain completed inspection forms for at least 3 years. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the Williams Compliance Plan o(J0R/o0 - 7 - construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. z • Significant amounts of sediment that leave the ROW will be cleaned up within 24 = t= hours of deposition and either (1) placed back onto the site and stabilized or (2) 'C4 /. properly disposed. • Equipment, materials, and workers must be available for rapid response to BMP vi o failures and emergencies. w 1; U) • Salvaged topsoil will be spread evenly over all areas to be reclaimed. w 0 • Following replacement, topsoil will be stabilized against wind erosion by use of u mulches, surface soil sealers, and/or erosion control fabric. = d I— Ulm • Minimum grading will be conducted to establish staging areas. z o.. • Locate staging areas in existing contractor yards; commercial areas used for w w' storing and maintaining equipment; previously cleared, graded, or paved areas; or other level areas where grading and vegetation clearing is not required. o • Erosion and sediment controls will be used during and after construction, s 0: including siltation fences, certified weed -free hay bales, interceptor dikes, u. ~O sediment traps to avoid substantial soil loss and displacement. w z U �. • Install baffle boards where needed on steep slopes. p z • Where necessary, armor bank slopes with riprap. • Silt fences or straw bale dikes will be used to intercept and retain small amounts of sediment carried by sheet flow from disturbed areas during construction activities and to prevent this sediment runoff from leaving the project site. • Silt fencing or straw bale dikes will be placed along the base of fill slopes and above cut slopes. If the side slope cut is longer than 200 feet, an erosion control blanket will be used with reseeding. The cut slope will not exceed 1.5:1, and the fill slope will not exceed 2:1. • Any soil stockpiled next to trenches that are subject to erosion will either be located on the upslope side of the trench, protected using straw bale dikes or silt fences, or covered with plastic, as appropriate. • The contractor must have on hand a minimum of eight straw bales at all times for emergency sediment containment purposes. Williams Compliance Plan 0&/08/(X) 8 • Repair existing roads upon completion if additional disturbance is created from fiber optic line installation construction activities. • Installation of steel casing will require standard cut - and -cover trenching techniques. Trenches should be backfilled with select backfill and compacted. Trench plugs should be installed periodically within the trench to prevent piping of the backfill and to limit groundwater movements. Water trapped at the trench plugs should be captured in a French drain and tightlined below the right -of -way and off the potential landslide area. • In some landslide areas it may be possible to span the affected area by stringing the fiber optic conduit and line aboveground on poles. Poles within the landslide mass may also be feasible where the landslide plane is below the depth of embedment of the pole, allowing the pole to move with the landslide mass. • Site visits should be performed for all active and potentially active landslide areas. Site visits to potentially active landslide areas are necessary to confirm preliminary evaluation that these areas are not currently active as well as to mark the limits of areas where special construction will be required. • Where HDPE conduits have been installed by plow, the resulting furrowed soil will be leveled by compaction. For installation by drilling, any extra excavated material from the boring will be hauled to an authorized offsite disposal area. For installation by open -cut trenching, the trench will be backfilled. • All temporary soil erosion control measures will be removed within 30 days after final ROW stabilization is achieved. Trapped sediment and disturbed soil areas resulting from the removal of temporary measures will be stabilized to control further erosion and sedimentation. F. Historic and Cultural Resources Should items of historical and cultural importance be accidentally found during construction activities, the following guidelines would be followed: • Construction activities in the immediate area of the accidental find will be halted. • The contractor or owner will notify its cultural resources consultant on the project who will, in conjunction with the contractor or owner, notify OAHP by telephone and, if the findings are human remains the applicable County Coroner and Sheriff. These parties will be notified within 24 hours of an accidental find. • Specific OAHP instructions concerning an accidental find resulting from the notification(s) described above will be followed on a case -by -case basis. At a minimum, sufficient archaeological work will be perfornmed on the accidental find location to stabilize deposits, protect deposits from scavengers or looters, and to collect readily available samples (e.g., for radiocarbon dating) which may help Williams Complinncc Plan 06/08/00 9 pinpoint the age of deposits or, in the case of burials, the presence of data which may serve to identify lineal or cultural descendants. • The owner and its cultural resources consultant will consult with OAHP to follow through on the course of action selection to comply with Section 106. This may require development of an MOA or implementation of actions involving the find that satisfy Section 106, and may involve consultation with Native American groups. In any case, construction will remain halted in the immediate area of the accidental find until OAHP indicates in writing that the undertaking may proceed in the area. • In the case of an accidental find of human remains, all relevant recommendations (e.g., NAGPRA legislation) regarding treatment of such remains will be followed. The owner recognizes the importance of providing careful and respectful treatment of human remains recovered as an accidental find or as part of an archaeological investigation. If the proposed undertaking is not on Federal or Native American lands, consultation prior to implementation is not required. In the event of an accidental find of human remains, the owner will contact OAHP for appropriate Native American groups with which to consult. In coordination with OAHP and all interested parties, a decision will be made for the treatment of the remains. G. Spills and Materials Management • All onsite vehicles will be monitored for petroleum leaks, and all spills will be cleaned up immediately upon discovery. • Store hazardous materials, chemicals, fuels, and oils and fueling of construction equipment a minimum of 200 feet from any drainage, wetland, water supply, well, spring, or other water feature. • Any hazardous waste material generated by project construction and operation will be disposed of in the manner specified by local and state regulations or by the manufacturer. Site personnel will be instructed to be aware of this requirement. • Keep cleanup materials and equipment readily available onsite, either at an equipment storage area or on the contractor's trucks. • Locate equipment wash stations on level (0 to 2% slope), vegetated areas at least 200 feet from the margins of drainages or wetlands. Washing will be conducted in a manner that avoids runoff from the washing area. • Where paved surface restoration requires the use of concrete, a concrete washout will be used to rinse or clean tools. The securely anchored washout, constructed using a straw bale perimeter and plastic sheeting ground cover, will be adequately sized to contain all material washed into it. Following the completion of activities Williams Compliance Plan 06/0R/00 - 10- MY, «r. ».w.ma :! dwWMta requiring concrete resurfacing, all contents contained in the washout will be properly disposed of offsite. • Spills will be documented and a record of the spills will be kept with the SWPPP. If a spill occurs that is reportable to the federal, state, or local agencies, the resource monitor is responsible for the reports. • All waste material will be collected and stored in a secure container and removed from the project ROW. The waste container will be inspected regularly and the contents will be disposed of properly by the owner. No waste oil or other petroleum -based products will be disposed of offite (e.g., buried, poured), but will be removed offsite for proper disposal. Litter generated by the construction crew will be picked up and properly disposed of on a daily basis. • All sanitary wastes will be collected from portable units as required and properly disposed of offsite. • When boring requires the use of drilling mud, such as bentonite, no discharge of excess material or site runoff will be allowed into drainages or wetlands. Slurry tanks will be sized to hold excess material completely so that there is no spillage. The casing pipe entry point will be appropriately enclosed and equipped with a sump pump to reclaim or discharge excess slurry or discharge it to a reuse or disposal tank. Earth spoiled by drilling slurry will be removed and disposed of by the contractor, and the ROW will be refilled with clean material. Upon completion of construction, the ROW will be restored to a condition equal to or better than its original condition. H. Vegetation • All steep, unstable slopes will be left vegetated whenever possible. • Compaction and grading of soils close to mature trees should be avoided to prevent damage to root systems. • Limited removal and disposal of trees and/or brush within the construction zone and as per engineering drawings and typicals is expected. If required, a subcontractor will cut brush and trees as needed to create a clean path up to 10 feet wide for construction equipment access. Where this is needed, all trees and shrubs will be cut flush with the ground (existing ground). Some downed trees may be left on site to provide habitat for small mammals, birds and insects and to provide nutrient cycling processes. Smaller limbs and brush may be chipped to aid erosion control and to reduce fire hazard. • Mixing of topsoil with subsoil will be prevented by using topsoil segregation mcthods. When implementing these methods, topsoil will be windrowed separately from subsoil. Topsoil will be stripped from the subsoil storage area and stored along the edges of the corridor with other stockpiled topsoil. For deep Williams Compliance Ilan OWOK /00 A10 41!334.41..4*.4 :.�a�+ax is rrs�t.4,.f farm soils (that is, in floodplain and stream terraces), at least 12 inches of topsoil will be segregated. Where soils are shallow to bedrock or have stony subsoil, all available topsoil will be separated from coarser parent material. • Topsoil and other suitable growing media will be used to restore suitable plant growing conditions after construction is completed. • Final stabilization for the purpose of terminating coverage under the general permit is achieved when all soil - disturbing activities are completed and either (1) a uniform vegetative cover of 70% has been established or (2) equivalent stabilization measures (e.g., erosion control blankets) have been installed. • All groundbreaking disturbances will be seeded with native species for erosion control. • Seeding or mulching will be done only in those portions of the right -of -way that were vegetated prior to the start of construction. Seeding or mulching will be conducted if construction halts for more than 21 days during the rainy season (i.e., October 15 through April 15). I. Water Quality • Soil disturbances on slopes of more than 40% will be avoided as much as possible. • The use of biodegradable matting will be used only in areas of steep slopes that are near critical areas (e.g., streams). • Topsoil will be preserved and replaced to the greatest extent possible to maximize the effectiveness of revegetation efforts. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid substantial soil loss and displacement. • Where fertilizers are used, they will be applied only in the recommended amounts. Once applied, the fertilizer will be worked into the soil to limit exposure to storm water. Fertilizer spills will be cleaned up immediately. Willianu Compliance Plan 06/OH/O0 - 12- • Watering trucks or other appropriate dust - abatement measures will be used to control dust generated during construction as required to prevent fugitive dust emissions. Applying water to the point that runoff occurs will be avoided. J.

In the City of Tukwila, the fiber optic line will be placed in approximately 4.25 miles of the East Marginal Way and Airport Boulevard right -of -way (see vicinity map). The fiber optic line is proposed to assist in meeting the growing demand for network capacity in the Pacific Northwest and to connect existing POP sites in Portland and Seattle. Installation of the line will expand the Pacific Northwest's national telecommunication infrastructure. Construction is proposed to begin in July 2000, after receipt of the necessary authorizations from the applicable governing agencies. Construction is expected to take approximately 6 months. Construction on some segments of the project ROW will be subject to various wildlife and fisheries avoidance windows so that potential disturbance of sensitive species can be avoided. Testing will occur in December 2000 with Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 1 City of Tukwila Shoreline Application July 2000 commercial operation scheduled to begin January 1, 2001. A detailed project description has been included with this application package. 1.3.2 Route in the City of Tukwila In the City of Tukwila, the ROW will be located along East Marginal Way and Airport Boulevard in: ■ Sections 22, 15, 10, 9, 4, 3, Township 23 North, Range 4 East, and ■ Section 33, Township 24 North, Range 4 East. The fiber optic line will parallel East Marginal Way and Marginal Way starting at 152nd Street and ending just north of 81st Street. It follows the west side of the two roads until it reaches Norfolk Street, where it is crosses Marginal Way and continues northward on the east side. 1.4 CONSTRUCTION 1.4.1 Construction Management A proper management structure, adequate training of field personnel, an environmental training program, and the ability to respond to changing circumstances are critical components to the success of the proposed fiber optic line. Training classes for the contractor and construction crews will be held covering issues such as environmental protection, safety, spill prevention and response, fire prevention and management, and proper management of stormwater runoff. The field management structure will include engineering, construction, and environmental personnel such as spread superintendents, spread supervisors, and contract compliance inspectors. The contractor and Williams' spread superintendents will be onsite to address engineering questions, make field decisions, and coordinate with permitting agencies. The spread superintendents have overall responsibility for onsite decisions and direct reporting responsibilities to the Williams' project manager for contract compliance. The superintendents also have the ability to shut down the construction operations in case of environmental noncompliance, emergencies, safety issues, and disputes with the construction contractor. Williams' spread supervisor will be onsite for each contractor to oversee the individual contract compliance inspectors and work with the contractor to resolve field conflicts. The spread supervisor will report directly to the construction superintendent and also perform most of the administrative duties. The spread supervisor will communicate daily to the appropriate personnel all construction activities related to compliance, safety, and administration. Contract compliance inspectors will be assigned to each construction crew to observe their work. If multiple crews work in the same area, one inspector could monitor more than one crew. The inspector will check implementation of the erosion protection measures. The contract compliance inspector will be trained on environmental issues that Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 2 City of Tukwila Shoreline Application July 2000 z z 6 J0 000 J = 1— w0 a =w z� i- 0 wF- O• N O f—, w W = U' 1 11.z U N` 0 z may be encountered during the construction project and will have immediate access to biologists, archaeologists, and geologists. A pre - construction meeting will take place approximately one week prior to construction. Those present will include Williams' staff, the contractor and foreman, utility owners, and the appropriate City of Tukwila agencies. The agenda of the meeting will include introductions of all involved parties; a discussion of the construction schedule, the construction techniques, safety issues, and traffic control; and the dissemination of contact names and numbers of all involved parties. Conduit and line installation will not threaten overhead utilities due to the amount of vertical clearance under the utilities. For underground facilities, the "One Call" utility location services will be contacted a minimum of 48 hours before construction. The "One Call" services will alert all registered utilities about the scheduled construction activities, allowing the utilities to identify the location of their underground facilities and thus greatly reduce the possibility of interruptions in utility services. 1.4.2 Construction Techniques The Duwamish River will be crossed by attachment of conduit to the East Marginal Way overpass. The conduit will be attached under the bridge in a reinforced fiberglass casing. The fiber optic line will be in the shoreline are for approximately 600 feet. After crossing the river, the fiber optic line follows the western edge of the East Marginal Way road prism by the method of open- trenching, and will be within 200 feet of the shoreline jurisdiction for approximately 1600 feet across from the South Boeing Access Road. Open trenching will be used due to the number of existing utilities located belowground and the number of conduits to be installed. Construction will take approximately 6 to 8 weeks. An open trench is a continuous trench 2 to 3 feet wide and approximately 48 inches deep, depending on the location of foreign utilities belowground. A probe will locate foreign utilities prior to any digging with a backhoe. Once the locations of the foreign utilities have been determined, a backhoe will remove the asphalt and material above the foreign utilities. Digging by hand with spades will remove the material around the foreign utilities. Once a sufficient amount of material has been removed, the conduits will be inserted either below or above the foreign utilities, whichever is appropriate. Select backfill will replace the material that has been removed. The backfill consists of a sand mixture or light gravel, which will be soft and compactable. Once the backfill material is compacted, the asphalt will be replaced according to the applicable specifications. An illustration of a typical open trench construction method is included with the application package. Operation activities will consist of maintaining erosion control measures and repairing or replacing line conduit. After installation, access to inspect damaged areas will be accomplished via manholes in public streets. Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 3 City of Tukwila Shoreline Application July 2000 J 1.5 ANALYSIS 1.5.1 General Shoreline Regulations (TMC 18.44.110) All uses within the shoreline overlay district must conform to the following general regulations: 1. The use is in conformance with the regulations of the underlying zone district. The zoning adjacent to the Duwamish River, where the fiber optic line is within the shoreline zone, is designated Manufacturing Industrial Center/Heavy Industrial. According to the City of Tukwila Zoning Code Chapter 18.34, fiber optics is a permitted use within this zone. 2. The use does not conflict with the goals and policies of the Shoreline Master Program or the provisions of the Shoreline Act and shoreline regulations. According to the City of Tukwila Shoreline Master Plan Chapter 18.44.020, all shorelines in the City of Tukwila are designated `urban.' The Williams fiber optic line falls within this use. 3. No structures or accessory facilities shall be located over the river. Within the City of Tukwila, the fiber optic line will be placed underground by the open trench method and be attached to the East Marginal Way overpass. The conduit will be attached under the bridge in a reinforced fiberglass casing. After crossing the river, the fiber optic line will be installed below ground along the western edge of the East Marginal Way South road prism and will be within the 200 -foot shoreline jurisdiction for approximately 1600 feet across from the South Boeing Access Road. There will be no structures or accessory facilities located over the river. 4. There shall be no disruption of existing trees or vegetation within the river environment, unless necessary for public safety or flood control, or if allowed as a part of an approved Shoreline Substantial Development permit. The Duwamish River will be crossed by attachment of conduit to the East Marginal Way overpass, and will stay outside of the designated stream buffers. It will therefore not be necessary to remove any existing trees or vegetation within the river environment, or along the 1600 feet on South Boeing Access Road. 5. No effluents shall be discharged into the Green River which exceeds the water quality classification as established by the State for the adjacent portion of the river. Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 4 City of Tukwila Shoreline Application July 2000 Within the City of Tukwila, the Williams fiber optic line will cross the Duwamish River once and will be within 200 feet of the river for approximately 1600 feet. The fiber optic line will cross the Duwamish River at the East Marginal Way South overpass. Erosion and sediment controls including silt fences will be used during and after construction. No effluents will be discharged into the Green River. No tree removal will occur within the City of Tukwila and no re- planting or seeding will be necessary. A Stormwater Pollution Prevention Plan (SWPPP) has been prepared for the project, including detailed descriptions of typical Best Management Practices (BMPs), and when and how they are to be applied. A copy of the SWPPP will be submitted to the contractor prior to the start of construction. 6. All State and federal water quality regulations shall be strictly complied with. As part of the Joint Aquatic Resources Permit Application (JARPA), Clean Water Act Section 401 and Section 404 Permit/ applications have been submitted to the appropriate agencies. 7. Wildlife habitat in and along the river will be protected. Construction corridor avoidance windows have been identified to minimize and avoid sensitive resources during critical times. Erosion and sediment controls will be used to ensure minimal disturbance to the river. Revegetation, where appropriate, will occur as soon as possible to minimize changes to these fish and wildlife species habitat as well as minimize corridor fragmentation. Wildlife species potentially present in the Tukwila project ROW include: Bald Eagle, Osprey, Vaux's swift, Great blue heron, Cavity nesting ducks, Pileated woodpecker, Waterfowl, Townsend's big -eared bat, Western pond turtle, Oregon spotted frog, Western toad, and Valley silverspot. The following measures have been developed to avoid or minimize potential impacts to wildlife from implementation of the proposed project: Reptiles and amphibians • At seasonal streams that support suitable habitat for non- federally listed special status amphibians and reptiles where drilling is infeasible, impacts will be avoided initially by determining presence or absence of these species, followed by constructing barrier fencing, and relocating individual animals during construction. General wildlife • Retain qualified biologists and resource specialists to monitor construction activities near specified sensitive biological areas. • Fill or cover open trenches. Any open trenches will be filled with earth material or covered with plywood or other material to prevent entrapment of wildlife at the end of each work day. Both ends of any open trench will be Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 5 City of Tukwila Shoreline Application July 2000 1 sloped to form escape ramps before covering. If wildlife are found in the trench, they will be removed by a qualified permitted biological monitor before resumption of work in that trench segment. Williams will specify this requirement in the agreements with all construction contractors. • Drill sensitive rivers, streams and wetlands. In order to avoid impacts to Z wetlands and riparian areas, and to species associated with them, all rivers, a streams and wetlands within the ROW that are biologically sensitive will be ,� w ce drilled. -J C.) Bald eagle o • No construction activity will occur within 2,600 feet of an open nest or 1,300 J =' feet of a screened nest between January 1 and August 15, unless individual co 1.- w consultation with a WDFW biologist determines that the buffer can be w o. reduced. Between November 1 and April 1, no construction activity will occur within u • 328 feet of winter roosts during the time period between one hour before c a sunset and one hour after sunrise. _ • Within 2,600 feet of known nest or communal roost sites, or areas of potential ? t- foraging habitat, no large cottonwoods or Douglas firs suitable for use as Z o perching or roosting habitat will be removed. w 2 m Lii • No new roads will be constructed within 100 feet of bald eagle nesting, v o wintering or foraging areas, streams, or areas where primary bald eagle food 0 P- o '. stocks are present. w w LL � Oregon spotted frog _ 0 • Drill wetlands containing potential suitable habitat. id z' • Do not flood or drain areas of potential habitat. • Within areas of potential hibernation habitat, do not disturb or alter muddy 0 z substrates. 8. All perimeters of landfills or other land forms susceptible to erosion shall be provided with vegetation, retaining walls or other satisfactory mechanisms for erosion prevention. Erosion and sediment controls will be used during and after construction, including silt fences, certified weed -free hay bales, interceptor dikes, and sediment traps to avoid substantial soil loss and displacement. All steep, unstable slopes will be left vegetated whenever possible. All groundbreaking disturbances will be seeded with native species, if appropriate, for erosion control. The environmental resource coordinator will work with the contract compliance inspector and biologists, geologists and agencies, and the engineering and construction representatives to resolve conflicts and coordinate resource avoidance and protection. The environmental resource coordinator will patrol the construction site periodically to help monitor implementation of the resource protection measures. Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 6 City of Tukwila Shoreline Application July 2000 v) Best Management Practices (see attached) will be used to minimize the potential for sediment transport to surface waters during and following installation of the line. A Stormwater Pollution Prevention Plan (SWPPP) has been prepared for the project, including detailed descriptions of typical BMPs, and when and how they are to be applied. A copy of the SWPPP will be submitted prior to the start of construction. BMPs and erosion control measures for this project will be used to isolate active construction areas from surface waters, and to minimize the sediment concentration of surface runoff. The project also includes the use of environmental monitors who will coordinate with construction crews to ensure that all necessary BMPs are followed and erosion control measures are installed and functioning properly. 9. All necessary permits shall be obtained from Federal, State, County or Municipal agencies. All local, state, and federal applications have been filed with the appropriate agencies, these include: • Joint Aquatic Resources Permit Application (JARPA) — U.S. Army Corps of Engineers (COE) • National Historic Preservation Act: Section 106 — Washington State Office of Archaeology and Historic Preservation (OAHP) • Aquatic Resource Use Authorization Notification — Washington State Department of Natural Resources (WDNR) • Aquatic Lands Easement — WDNR • Application for General Discharge Stormwater Associated with Construction Activity — Washington Department of Ecology • Application for Utility Permit and Franchise — Washington State Department of Transportation (WSDOT) • Hydraulic Project Approval — Washington Department of Fish and Wildlife The following have been submitted to the City of Tukwila: • Shoreline Substantial Development Permit, City of Tukwila • JARPA • Application for Franchise, City of Tukwila 10. Dredging for purposes other than for navigational improvements or flood control is prohibited. In the City of Tukwila, no dredging will take place for the Williams fiber optic line installation project. Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 7 City of Tukwila Shoreline Application July 2000 r. t 11. Mining is prohibited along the river shoreline. The Williams fiber optic line installation project will not involve mining. 12. Solid waste disposal is prohibited along the river shoreline. A SWPPP has been completed. No solid waste will be disposed along the river shoreline. Surface reclamation will involve the clearing of construction debris from the right -of -way to leave the soil in the condition it was found. Staging areas for construction equipment, materials, fuels, lubricants, and solvents will be established along the project ROW during construction to allow more efficient use and distribution of materials and equipment. Whenever possible, staging areas will be located on private lands in existing contractor yards; existing commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or level areas where grading and vegetation clearing are not required. The construction contractor, as needed, before and/or during construction typically selects staging areas. Each area is expected to be 4 to 5 acres in size. To ensure that sensitive environmental resources are adequately protected or are avoided, the locations of staging areas will be determined in consultation with environmental resource specialists. Since fuels, lubricants, and solvents will be stored in staging areas, the staging area will be located outside the shoreline zone. 13. No property will be acquired for public use without dedication by or just compensation to the owner. All work in the City of Tukwila will occur within the Military Road right -of -way. Williams is in the process of obtaining franchise agreements. 14. Landfilling is prohibited within the river channel unless such landfill is determined by the Planning Commission to protect or promote the public interest. Landfilling will not occur within any river channels in the City of Tukwila. 15. Not withstanding any provisions of the Code to the contrary, removal of any cottonwood tree within the river environment or the low impact environment, which tree is 12 inches or greater in diameter as measured 4.5 feet above grade, shall be subject to the requirements of TMC Chapter 18.54, Tree Regulations. There are no cottonwood trees within the Duwamish River environment at the location of the crossing or parallel to the river in the project area. The Williams Williams Communications, Fiber Services Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 8 City of Tukwila Shoreline Application Judy 2000 fiber optic line will cross the Duwamish River by attaching the conduit under the East Marginal Way overpass.

Trenches will be 4 feet wide and 48 inches deep. Trenching is typically done with a rubber -tired backhoe or an excavator. A backhoe weighs approximately 8 tons. If conditions do not allow for small areas to be backfilled at the end of each day, appropriate safety, erosion, and wildlife control features will be installed. Up to a 30 -foot wide ROW is needed where trenching is needed to take place. Ten feet is required for tracked/rubber -tired equipment and vehicular construction traffic. The construction corridors will typically be confined to within the existing ROW. [The following lists include, but are not limited to, property owners within 500 feet of the subject property.] 6.

The proposed right -of -way (ROW) crosses numerous county and city jurisdictions and requires approvals and permits from various federal, state, and local agencies. The Washington Department of Ecology (Ecology) has been identified as the lead agency for State Environmental Policy Act (SEPA) compliance for the project. The purpose of this report is to document the actions Williams Communications has taken to identify wetlands and streams, and their buffers, within the City of Tukwila portion of the ROW. In the City of Tukwila, the fiber optic line ROW will be placed in approximately 4.25 miles of the Pacific Highway and Airport Boulevard ROW. There will be a total of 3,896 square feet (0.09 acre) of ground breaking impact to resources in the City of Tukwila, all of which are stream buffers. Wetlands and streams were identified as defined in the Sensitive Area Ordinance Tukwila Municipal Code Chapter 18.45. Wetlands were identified using the U.S. Army Corps of Engineers 1987 Wetland Delineation Manual (Environmental Laboratory 1987), the 1997 Washington State Wetlands Identification and Delineation Manual (Ecology 1997), and best professional accepted field standards. Wetlands and streams identified in this report are subject to verification by the City of Tukwila and the U.S. Army Corps of Engineers (Corps). Final determination of wetland boundaries is the responsibility of these agencies. 2 PROJECT DESCRIPTION Williams Communications (Williams) proposes to install approximately 176 miles of fiber optic line from Portland, Oregon to Seattle, Washington. The fiber optic line installation will assist in meeting the growing demand for network capacity in the Pacific Northwest and to connect existing points of presence (POP sites) in Portland and Seattle. Installation of the line will expand the Pacific Northwest's national telecommunications access and enhance the capability and reliability of the region's telecommunication infrastructure. Construction will begin in June 2000, after receipt of all necessary authorizations from the applicable governing agencies. Construction is expected to take approximately 6 months. Construction on some segments of the ROW will be subject to various avoidance windows so that potential disturbance of sensitive species can be avoided.

Testing would occur in December 2000 with commercial operation scheduled to begin January 1, 2001. 2.1 Project Location in City of Tukwila In the City of Tukwila, the ROW will be located along Pacific Highway and Airport Boulevard in: ~ w • Sections 22, 15, 10, 9, 4, 3, Township 23 North, Range 4 East, and -J 0 ■ Section 33, Township 24 North, Range 4 East. 0 co o COL The fiber optic line will parallel Pacific Highway and Marginal Way starting at 152nd -J F-- Street and ending just north of 81st Street. It follows the west side of the two roads until it F- M p reaches Norfolk Street, where it is crosses Marginal Way and continues northward on the east 2 side (see map on following page). Q =d 2.2 Fiber Optic Line Characteristics ~ i z1._ In the City of Tukwila, the fiber optic line system will consist of belowground w o� components and an aboveground component. The belowground facilities are the fiber optic line 2 D. and conduit, and handholes. The aboveground element is the line marker posts. 0 O 0 H- Fiber optic line is made up of bundled glass optical fibers in a high- density polyethylene w w conduit. The conduit will have an outside diameter of 1.25 to 1.5 inches. The City of Tukwila 1- portion of the ROW will have 6 to 20 conduits. u- o Ili z Handholes are usually placed at intervals of 3 to 5 miles to serve as splice points and to 1 assist fiber optic line installation and maintenance. Road shoulders or other easily accessible z I-- areas are the preferable locations for handholes. Locations for the placement of the handholes along the ROW will be selected to avoid sensitive biological, archeological, and geological resources. Cable marker posts will be located at approximately 700 to 1,000 -foot intervals to alert people to the presence to the fiber optic line. The posts are typically 3.5- inch diameter round PVC posts with embossed lettering 4 feet aboveground. 2.3 Construction Techniques 2.3.1 Staging Areas and Access Roads Staging areas for construction equipment, materials, fuels, lubricants, and solvents will be established off -site along the project ROW during construction to allow more efficient use and distribution of materials and equipment. Each area is expected to be 4 to 5 acres. Whenever possible, staging areas will be located on private lands in existing contractor yards; existing Williams Communications, Inc.

Access to the project ROW will be by existing local city, county, or state roads. After completion of fiber optic line installation, roads will be repaired and/or improved, if necessary. Staging areas are not selected until the early stages of construction planning. Selection of z this project component will be determined after consultation with qualified biologists and archeologists to ensure that sensitive environmental resources are adequately protected or 6 = avoided. All staging areas will be located outside all sensitive resources and their buffers. v o co w= 2.3.2 Conduit and Fiber Optic Line Installation n � w0 Conduit and fiber optic line installation will not threaten overhead utilities because of the amount of vertical clearance under the utilities. For underground facilities, the "One Call" utility location services will be contacted a minimum of 48 hours before construction. The One N cn a Call services will alert all registered utilities about the scheduled construction activities, allowing 1 _ the utilities to identify the location of their underground facilities and thus greatly reduce the z �- possibility of interruptions in utility services. z O w In the City of Tukwila, the construction methods being used to bury the conduit will be 2 0 directional drilling under all roads, and trenching in all other areas, including three stream o N. buffers. These methods are described below. Refer to Appendix F for illustrations of typical iw w construction methods. • 0 L: o ..z. w U - — _ O '—. Trenches will be 4 feet wide and 48 inches deep. Trenching is typically done with a z. rubber -tired backhoe or an excavator. A backhoe weighs approximately 8 tons. If conditions do not allow for small areas to be backfilled at the end of each day, appropriate safety, erosion, and wildlife control features will be installed. Up to a 30 -foot wide ROW is needed where trenching is needed to take place. Ten feet of clearance is required for tracked/rubber -tired equipment and vehicular construction traffic. The construction corridors will typically be confined to areas within the existing ROW. 2.3.2.1 Trenching 2.3.2.2 Directional Drilling Directional drilling will be used in various locations along the ROW to cross areas where surface disturbance must be avoided (e.g., crossing railroads, highways, rivers, sensitive streams, and wetlands). Directional drill lengths could range from less than 100 feet to 4,300 feet at the Columbia River crossing. To complete the drill, a work area is established on each side of the crossing. For river, stream, and wetland crossings, the work areas, when possible, will be located at least 150 feet from the bank or edge of the wetland resource. One work area contains the "pilot hole" and drilling equipment. The other work area contains the "receiving hole" where the drill bit emerges. Depending on the length of the drill, the drill entry areas range from 2 feet Williams Communications, Inc.

Drilling equipment most suitable for site - specific conditions will be used for each drill. Silt fences, straw bales, and other erosion control measures will be installed around these work areas. Approximately 500 feet of drilling could be completed per day per drill rig. During the drilling process a bentonite slurry is typically pumped through the drill hole to help lubricate the drill bit, prevent the drill tunnel from collapsing, and carry drill cuttings to the surface. Bentonite is a naturally occurring clay known for its hydrophilic characteristics. The slurry is pumped through the drill hole, collected at the surface, passed through machinery to remove the drill cuttings, and then recirculated through the hole. The slurry is held in a pump truck during drilling, and stored in tanks at the drill site when not in use, if necessary. Any excess slurry remaining after the drill is complete will be removed from the site and either reused by the drilling contractor or disposed of at an appropriate facility. 2.4 Monitoring Before beginning construction, Williams and the onsite biological monitor will review the ROW to determine the most appropriate access method for each resource and will note these methods on the construction drawings. A proper management structure, adequate training of field personnel, an environmental training program, and the ability to respond to changing circumstances are critical components to the success of the fiber optic line installation. Training classes for the contractor and construction crews will be conducted to address issues such as environmental protection, safety, spill prevention and response, fire prevention and management, and proper management of stormwater runoff. The field management structure will include engineering, construction, and environmental personnel such as spread superintendents, spread supervisors, contract compliance inspectors, environmental resource coordinators, and biological, archeological, and geotechnical support. The roles and responsibilities of each onsite representative will be clearly understood and communicated during the training program and are summarized below. The contractor and Williams' spread superintendents will be onsite to address engineering questions, make field decisions, and coordinate with permitting agencies. The spread superintendents have overall responsibility for onsite decisions and will directly report to the Williams project manager for contract compliance. The superintendents also have the ability to shut down the construction operations in case of environmental noncompliance, emergencies, safety issues, and disputes with the construction contractor. Williams' spread supervisor will be onsite to oversee the individual contract compliance inspectors and work with each contractor to resolve field conflicts. The spread supervisor will report directly to the spread superintendent and also perform most of the administrative duties. The spread supervisor will communicate daily all construction activities related to compliance, safety, and administration. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 4 Wetland and Stream Assessment Report City of Tukwila, Washington March 2000e • Contract compliance inspectors will be assigned to each construction crew to observe their work. Where crews work in the same area, one inspector can monitor more than one crew. The inspector will monitor the environmental resource concerns and check implementation of the erosion protection measures. The contract compliance inspector will be trained on environmental issues that may be encountered during construction of the fiber optic line and will have immediate access to biologists, archeologists, and geologists. Q F=-Z The environmental resource coordinator will work with the contract compliance W inspector, biologists, archeologists, geologists, agencies, and the engineering and construction 6 v representatives to resolve conflicts and coordinate resource avoidance and protection. The 0 O u) o environmental resource coordinator will patrol the construction site periodically to help monitor ui w implementation of the resource protection measures. �w Biologists, archeologists, and geologists will be onsite during construction. They will w O locate and stake sensitive resources in the field, note the resources on the construction drawings, g 5 and advise the contractor regarding the necessary protection methods. They will also coordinate with monitors from the appropriate agencies. = a. F- _. All levels of field management and construction personnel will be informed about ?

Appropriate personnel from the 2 regulatory agencies will be invited. v , O— Williams and its consultant team include contract compliance inspectors, environmental w w resource coordinators, resource experts, and spread superintendents and supervisors. Training =- seminars led by project managers and resource experts will be held before construction to u: 0 explain and educate construction supervisors and managers about the following: w U=. 0 F- • The need for and importance of resource avoidance and protection • Resource mapping format and interpretation of construction drawings • Resource protection staking methods • Construction process as it relates to required mitigation measures • Roles and responsibilities, and • Project management structure and contacts. All contract compliance inspectors will be required to complete an inspector training class. This class will address topics such as the environmental issues mentioned above, resource mapping and construction drawing interpretation, roles and responsibilities, and site safety. The contractor team will include the job superintendent, crew foremen, and crewmembers. The training and education will take place through several processes beginning with the preconstruction meetings and ending with training classes conducted before construction activities begin. Meetings with the contractor will be held prior to construction and will include discussions about the issues listed above. They will be used as an opportunity to reinforce the need for and importance of compliance with environmental resource avoidance and protection measures. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 5 Wetland and Stream Assessment Report City of'Tukwila, Washington March 2000e z The spread superintendents, supervisors, contract compliance inspectors, and environmental coordinators will regularly conduct meetings with the contractors' superintendents and foremen to coordinate the construction and mitigation processes. The contractors' foremen will be responsible for transmitting, on a weekly basis, the information discussed in the preconstruction meetings to the crewmembers. 3 STUDY METHODS 3.1 Background Data Collection and Review Jones & Stokes conducted background research to develop a database of potential and previously identified natural resources in the immediate vicinity of the ROW. Sources of background data include the following: • United States Geological Survey (USGS) topographic maps • National Wetland Inventory (NWI) maps • Federal Emergency Management Agency (FEMA) floodplain maps • Natural Heritage Program (NHP) threatened and endangered species maps • Natural Resources Conservation Service (NRCS) soil surveys, and • Washington Department of Natural Resources (WDNR) stream survey maps. Pertinent data were added to base maps that were then used in the field for identification of resources on the ground. 3.2 Field Procedures Biologists walked both sides of the Pacific Highway and Airport Boulevard ROW. The ROW extends 30 feet from the centerlines of the roads. Due to limited access beyond the ROW, the field crews made visual estimates of the size and condition of wetlands or streams outside and adjacent to the ROW. The field studies were conducted on December 14, 1999. Within the study area, wetlands and streams were delineated and mapped on the aerial photograph basemaps and topographic maps. Photographs were taken of each resource identified in the project ROW. Each resource was given a unique identifier based on the type of resource (e.g. W = wetland, D = drainage), location (e.g. topographic map name, township, range, section), and location sequence within each section from south to north. Only the first five characters of the topographic map name were used as part of the resource name. For example, the first stream found in Township 23 North, Range 4 East, Section 9 of the Des Moines topographic Quadrangle was given a resource number of D- DESMO- 23N4E9 -A. All resources included in this report will have a similar but unique resource number. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 6 Wetland and Stream Assessment Report City of Tukwila, Washington March 2000e 3.2.1 Wetlands Jones & Stokes conducted the wetland delineations using the 1987 Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987) and the 1997 Washington State Wetlands Identification and Delineation Manual (Ecology 1997). The 1987 manual is used by the Corps for application of Section 404 of the Clean Water Act, and by the City of Tukwila. The 1997 Ecology method is applied by the Department of Ecology for purposes of SEPA z compliance. These methodologies are summarized in Appendix E. Ce ijj For each wetland identified, a wetland determination field data sheet (Corps 1987 o 0 Routine Wetland Determination Form), as well as a wetland survey database form, aerial photo mapping (where 1 inch represents 200 feet or greater), and a photograph and photoform W (prepared by Jones & Stokes), were completed in the field. The wetland database was used to 2 o. provide additional wetland related information such as dominant species in the wetland buffer, w landscape position, unique features of the wetland, the wetland rating, and the maximum area potentially affected by construction. (See Appendix D for determination forms and Appendix G for resource maps.) = a h.. w z�.. F- 0 z�— Each wetland was rated based upon the entire area of the wetland, including any portion of the wetland that extends beyond the ROW. In the City of Tukwila, all wetlands were classified using methods outlined in the Sensitive Areas Ordinance of the Tukwila Municipal Code Chapter 18.45. 3.2.2 Streams Jones & Stokes conducted the stream delineations using stream typing criteria in Washington's forest practice rules (WAC 222 -16 -030) as modified by the Forest Practices Board Emergency Rule (adopted July 21, 1999). In addition, the City of Tukwila's Sensitive Area Ordinance Tukwila was used for local stream typing. WDNR Stream Typing maps were used in tandem with data collected in the field to classify the streams. The stream typing criteria classify an individual stream as a Type 1, 2, 3, 4, or 5 based upon size, slope, and beneficial uses such as fish, wildlife, and human uses. For each stream identified, a drainage field data sheet (prepared by Jones & Stokes) was completed in the field. The drainage field data sheet was used to collect information such as stream name, channel form, water depth, gradient, channel width, riparian vegetation, water quality, streambed substrate, fisheries habitat, associated basin or tributaries, and the maximum area potentially affected by construction. 4 RESULTS 4.1 General Site Conditions In the City of Tukwila, the fiber optic line will parallel Pacific Highway and Marginal Way starting at 152nd Street and ending just north of 81st Street. It follows the west side of the Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington 7 Welland and Stream Assessment Report Ciry of Tukwila, Washington March 2000e z two roads until it reaches Norfolk Street, where it is crosses Marginal Way and continues northward on the east side. Within this ROW, vegetation is dominated by non - native and invasive grass and shrub species, which is a result of continual ROW maintenance. The topography within the ROW ranges from generally level ground with shallow storm water ditches to steeply sloped land. Outside of the ROW, the topography is typically gently to steeply sloped on both sides of the road. In general, land is sloping downward to the east toward the Duwamish River. Surrounding land uses consists of residential housing, business, and open areas. 4.2 Wetlands One wetland, totaling approximately 45,000 square feet (1.03 acres), was identified just outside of the fiber optic line ROW in the City of Tukwila. A complete description of this wetland is presented in Appendix A. 4.2.1 Wetland 1 (W- DESMO- 23N4E9 -A) 4.2.1.1 Wetland Characteristics Wetland 1 is classified as a palustrine emergent (PEM) habitat and meets the criteria for a Type 2 wetland because it is greater than 1 acre in size. It is located just outside the eastern ROW between Pacific Highway and the on -ramp to State Highway 599. Dominant vegetation within the wetland includes cattail (Typha sp., OBL) and reed canarygrass (Phalaris arundinacea, FACW). Scattered patches of standing water were observed throughout the wetland. 4.2.1.2 Buffer The City of Tukwila assigns wetland buffer widths according to wetland classification. Because Wetland 1 is a Type 2, the required buffer width is 50 feet. Vegetation within the buffer consists of mature red alder (Alnus rubra, FAC) and black cottonwood (Populus balsamifera, FAC), in addition to Himalayan blackberry (Rubus discolor, FACU), and non - native grass species. 4.3 Streams A total of 4 streams were identified within the ROW in the City of Tukwila. A complete description of each stream is presented in Appendix B. Williams Communications, Inc.

It is located just north of South 130th Street and flows northeast through a large culvert under Pacific Highway. West of Pacific Highway, the flat channel has an ordinary high water mark (OHWM) width of approximately 5 feet. One small braid was observed just west of the culvert. The stream has a 15% gradient with a canopy cover of approximately 75% that consists primarily of shrub vegetation. The stream is approximately 15 feet below the road surface. East of Pacific Highway, the streambed was approximately 30 feet from the road and could not be directly observed due to limited access and visibility. In general, the vegetation adjacent to the stream consists of mostly herbaceous species with some conifers. Fish presence was unknown. 4.3.1.2 Buffer Vegetation within the buffer adjacent to the road consists of non - native grass species. The City of Tukwila categorizes its stream buffer widths according to stream classification. Stream 1 is a classified a Type 2, therefore the buffer width is 35 feet. 4.3.2 Stream 2 (D- DESMO- 23N4E9 -1) 4.3.2.1 Stream Characteristics Stream 2 meets the criteria for a Type 3 stream as defined by the WDNR and a Type 2 Stream by the City of Tukwila because it has a defined channel greater than 2 feet with a gradient less than 16 %, and for the City of Tukwila's rating, the stream yields a watercourse point total between 11 and 20. It is located just east of Pacific Highway south of the Duwamish River. This body of water is a tributary of the Duwamish River, and appears to have been dredged in the past with the spoil material deposited on the banks. The u- shaped channel has an OHWM width of approximately 10 feet, a gradient of about 2 %, and a canopy cover of 5 %, which consists of herbaceous vegetation. Characteristics of the streambed, as well as approximate water depth, could not be determined due to the low water quality. Fish presence was unknown. 4.3.2.2 Buffers Vegetation within the buffer adjacent to the road consists of non - native grass species. Stream 2 meets the criteria of a Type 2 stream, therefore the buffer width is 35 feet. Williams Communications, Inc.

It is considered a "Shoreline of the state" by the WDNR, and it yields a watercourse point total between 11 and 20 for the City of Tukwila's watercourse rating system. The surrounding area has been developed into heavy and light industrial businesses. Its OHWM is approximately 175 feet with a gradient of about 3 %. Streambed, water depth, and channel form could not be observed due to the size and low water quality of the river. Riparian vegetation includes herbaceous plants and some deciduous trees, however, no canopy cover was observed. Fish presence was unknown. 4.3.3.2 Buffers Vegetation within the buffer adjacent to the road consists of non - native grass species. The City of Tukwila classifies the Duwamish River as a Type 2 stream, therefore the buffer width is 35 feet. 4.3.4 Stream 4 (D- SEASO- 23N4E4 -1) 4.3.4.1 Stream Characteristic Stream 4 is Duwamish River, approximately 4 miles north of the crossing at Stream 3. At this location, the river parallels East Marginal Way on the west side for approximately 1,000 feet. Streambed, water depth, and channel form could not be observed due to the size and low water quality of the river. Some shrub vegetation was observed adjacent to the river, but no canopy cover was observed. Fish presence was unknown. 4.3.4.2 Buffers Vegetation within the 35 foot buffer adjacent to the road consists of non - native grass and shrub species. 4.4 Impacts/Mitigation In the City of Tukwila, the Williams Communications fiber optic line installment project will impact portions of three streams within the alignment ROW, resulting in a total of 3,896 square feet (0.09 acre) of ground breaking stream buffer impact (Table 1). The alignment has been placed outside of all other sensitive resources. Therefore, no wetlands or wetland buffers will be disturbed and no work will take place within any stream channel.

FISH AND WILDLIFE • Revegetation will occur as soon as possible to minimize changes to these fish and wildlife species habitat as well as minimize corridor fragmentation. FLOODPLAINS • Construction activities and permanent placement of the conduit, fiber optic line, handholes, OP -AMP stations, and all other project features will not increase flood heights or flood inundation boundaries within floodplains. • Construction staging areas will not be located within floodplains. • All materials such as the conduit, fiber optic line, and handholes will be buried, and thus anchored to prevent flotation, collapse, or lateral movement of the structure. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -2 Best Management Practices March 2000e GEOLOGY AND SOILS • Surface reclamation will involve the clearing of construction debris from the right -of -way (ROW) to leave the soil in the proper condition for planting, ensuring clearing of all construction debris and woody material. • On slopes, surface flow will be diverted by waterbars to a stabilized outlet using runoff i ~ diversions with a 2% outslope directed toward appropriate energy- dissipating structures. ce w Waterbars shall begin and end in undisturbed vegetation or soil. Woody material (such 6 as low shrubs) will not be removed, but rather placed back on the ROW with topsoil to v o provide a seed source and organic matter. ° w= • Other measures to restore or improve surface drainage measures already existing on the cn right of way might include tightlining discharge from water bars and diverting or collecting surface water coming on to the right -of -way and tightlining on the onflow to below the slope. � a • Where sediment could be transported onto a public road surface or other paved area by F_- equipment or vehicles accessing or leaving the construction site, sediment will be Z F— removed from the road immediately by shoveling or sweeping and transported to a I-- o sediment - controlled disposal area. 2 o • Inspections of site conditions and the BMPs will be conducted prior to anticipated storm o events to identify areas that may contribute to sediment discharge; corrective actions will w ~ be made as required. - v: u- O • All erosion and sediment control measures will be checked within 24 hours of each 0.5 -inch or greater rainfall event and every 14 calendar days during October 15 through v April 15, up until the time that site stabilization is achieved. During April 16 through p ~- October 14, the inspections will be conducted every 30 days. During extended storm events, inspections will be conducted at least once every 24 hours. • Inspection reports will be completed after each inspection and included in the project file. Ineffective temporary erosion control measures will be repaired or replaced as soon as possible but no later than 24 hours after identification. • Williams will retain completed inspection forms for at least 3 years. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington C -3 Appendix C Best Management Practices March 2000e ■ Significant amounts of sediment that leave the ROW will be cleaned up within 24 hours of deposition and either (1) placed back onto the site and stabilized or (2) properly disposed. • Equipment, materials, and workers must be available for rapid response to BMP failures and emergencies. z • Salvaged topsoil will be spread evenly over all areas to be reclaimed. CC W = u6 • Following replacement, topsoil will be stabilized against wind erosion by use of mulches, v p surface soil sealers, and/or erosion control fabric. u) W J = • Minimum grading will be conducted to establish staging areas. N u_ Wo • Locate staging areas in existing contractor yards; commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or other level areas u_ where grading and vegetation clearing is not required. d =W • Erosion and sediment controls will be used during and after construction, including z 1, siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid z o substantial soil loss and displacement. w w D p' • Install baffle boards where needed on steep slopes. ,0 S. o F- , no • Where necessary, armor bank slopes with riprap. = v P • Silt fences or straw bale dikes will be used to intercept and retain small amounts of - z sediment carried by sheet flow from disturbed areas during construction activities and to v ='. prevent this sediment runoff from leaving the project site. 0 z • Silt fencing or straw bale dikes will be placed along the base of fill slopes and above cut slopes. If the side slope cut is longer than 200 feet, an erosion control blanket will be used with reseeding. The cut slope will not exceed 1.5:1, and the fill slope will not exceed 2:1. • Any soil stockpiled next to trenches that are subject to erosion will either be located on the upslope side of the trench, protected using straw bale dikes or silt fences, or covered with plastic, as appropriate. ■ The contractor must have on hand a minimum of eight straw bales at all times for emergency sediment containment purposes. • Repair existing roads upon completion if additional disturbance is created from fiber optic line installation construction activities. • Installation of steel casing will require standard cut - and -cover trenching techniques. Trenches should be backfilled with select backfill and compacted. Trench plugs should be installed periodically within the trench to prevent piping of the backfill and to limit Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -4 Best Management Practices March 2000e groundwater movements. Water trapped at the trench plugs should be captured in a French drain and tightlined below the right -of -way and off the potential landslide area. • In some landslide areas it may be possible to span the affected area by stringing the fiber optic conduit and line aboveground on poles. Poles within the landslide mass may also be feasible where the landslide plane is below the depth of embedment of the pole, allowing the pole to move with the landslide mass. , _ I w • ■ Site visits should be performed for all active and potentially active landslide areas. Site j visits to potentially active landslide areas are necessary to confirm preliminary evaluation v v o that these areas are not currently active as well as to mark the limits of areas where c 0 special construction will be required. w • Where HDPE conduits have been installed by plow, the resulting furrowed soil will be o leveled by compaction. For installation by drilling, any extra excavated material from the boring will be hauled to an authorized offsite disposal area.

HISTORIC AND CULTURAL RESOURCES v Should items of historical and cultural importance be accidentally found during construction z, activities, the following guidelines would be followed: 0 (1) • Construction activities in the immediate area of the accidental find will be halted. 0 • The contractor or owner will notify its cultural resources consultant on the project who will, in conjunction with the contractor or owner, notify OAHP by telephone and, if the findings are human remains the applicable County Coroner and Sheriff. These parties will be notified within 24 hours of an accidental find. • Specific OAHP instructions concerning an accidental find resulting from the notification(s) described above will be followed on a case -by -case basis. At a minimum, sufficient archaeological work will be performed on the accidental find location to stabilize deposits, protect deposits from scavengers or looters, and to collect readily available samples (e.g., for radiocarbon dating) which may help pinpoint the age of deposits or, in the case of burials, the presence of data which may serve to identify lineal or cultural descendants. • The owner and its cultural resources consultant will consult with OAHP to follow through on the course of action selection to comply with Section 106. This may require development of an MOA or implementation of actions involving the find that satisfy Section 106, and may involve consultation with Native American groups. In any case, Williams Communications, Inc. Appendix C Fiber Optic Line Installation Project C -5 Best Management Practices Portland, Oregon to Seattle, Washington March 2000e construction will remain halted in the immediate area of the accidental find until OAHP indicates in writing that the undertaking may proceed in the area. • In the case of an accidental find of human remains, all relevant recommendations (e.g., NAGPRA legislation) regarding treatment of such remains will be followed. The owner recognizes the importance of providing careful and respectful treatment of human remains recovered as an accidental find or as part of an archaeological investigation. If the proposed undertaking is not on Federal or Native American lands, consultation prior to implementation is not required. In the event of an accidental find of human remains, the owner will contact OAHP for appropriate Native American groups with which to consult. In coordination with OAHP and all interested parties, a decision will be made for the treatment of the remains. SPILLS AND MATERIALS MANAGEMENT • All onsite vehicles will be monitored for petroleum leaks, and all spills will be cleaned up immediately upon discovery. • Store hazardous materials, chemicals, fuels, and oils and fueling of construction equipment a minimum of 200 feet from any drainage, wetland, water supply, well, spring, or other water feature. • Any hazardous waste material generated by project construction and operation will be disposed of in the manner specified by local and state regulations or by the manufacturer. Site personnel will be instructed to be aware of this requirement. • Keep cleanup materials and equipment readily available onsite, either at an equipment storage area or on the contractor's trucks. • Locate equipment wash stations on level (0 to 2% slope), vegetated areas at least 200 feet from the margins of drainages or wetlands. Washing will be conducted in a manner that avoids runoff from the washing area. • Where paved surface restoration requires the use of concrete, a concrete washout will be used to rinse or clean tools. The securely anchored washout, constructed using a straw bale perimeter and plastic sheeting ground cover, will be adequately sized to contain all material washed into it. Following the completion of activities requiring concrete resurfacing, all contents contained in the washout will be properly disposed of offsite. • Spills will be documented and a record of the spills will be kept with the SWPPP. If a spill occurs that is reportable to the federal, state, or local agencies, the resource monitor is responsible for the reports. • All waste material will be collected and stored in a secure container and removed from the project ROW. The waste container will be inspected regularly and the contents will be disposed of properly by the owner. No waste oil or other petroleum -based products will be disposed of onsite (e.g., buried, poured), but will be removed offsite for proper Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -6 Best Management Practices March 2000e disposal. Litter generated by the construction crew will be picked up and properly disposed of on a daily basis. • All sanitary wastes will be collected from portable units as required and properly disposed of offsite. • When boring requires the use of drilling mud, such as bentonite, no discharge of excess material or site runoff will be allowed into drainages or wetlands. Slurry tanks will be sized to hold excess material completely so that there is no spillage. The casing pipe entry point will be appropriately enclosed and equipped with a sump pump to reclaim or discharge excess slurry or discharge it to a reuse or disposal tank. Earth spoiled by drilling slurry will be removed and disposed of by the contractor, and the ROW will be refilled with clean material. Upon completion of construction, the ROW will be restored to a condition equal to or better than its original condition. VEGETATION • All steep, unstable slopes will be left vegetated whenever possible. • Compaction and grading of soils close to mature trees should be avoided to prevent damage to root systems. • Limited removal and disposal of trees and/or brush within the construction zone and as per engineering drawings and typicals is expected. If required, a subcontractor will cut brush and trees as needed to create a clean path up to 10 feet wide for construction equipment access. Where this is needed, all trees and shrubs will be cut flush with the ground (existing ground). Some downed trees may be left on site to provide habitat for small mammals, birds and insects and to provide nutrient cycling processes. Smaller limbs and brush may be chipped to aid erosion control and to reduce fire hazard. • Mixing of topsoil with subsoil will be prevented by using topsoil segregation methods. When implementing these methods, topsoil will be windrowed separately from subsoil. Topsoil will be stripped from the subsoil storage area and stored along the edges of the corridor with other stockpiled topsoil. For deep soils (that is, in floodplain and stream terraces), at least 12 inches of topsoil will be segregated. Where soils are shallow to bedrock or have stony subsoil, all available topsoil will be separated from coarser parent material. • Topsoil and other suitable growing media will be used to restore suitable plant growing conditions after construction is completed. • Final stabilization for the purpose of terminating coverage under the general permit is achieved when all soil - disturbing activities are completed and either (1) a uniform vegetative cover of 70% has been established or (2) equivalent stabilization measures (e.g., erosion control blankets) have been installed. • All groundbreaking disturbances will be seeded with native species for erosion control. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -7 Best Management Practices March 2000e f • Seeding or mulching will be done only in those portions of the right -of -way that were vegetated prior to the start of construction. Seeding or mulching will be conducted if construction halts for more than 21 days during the rainy season (i.e., October 15 through April 15). WATER QUALITY • Soil disturbances on slopes of more than 40% will be avoided as much as possible. • The use of biodegradable matting will be used only in areas of steep slopes that are near critical areas (e.g., streams). • Topsoil will be preserved and replaced to the greatest extent possible to maximize the effectiveness of revegetation efforts. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid substantial soil loss and displacement. • Where fertilizers are used, they will be applied only in the recommended amounts. Once applied, the fertilizer will be worked into the soil to limit exposure to storm water. Fertilizer spills will be cleaned up immediately. • Watering trucks or other appropriate dust - abatement measures will be used to control dust generated during construction as required to prevent fugitive dust emissions. Applying water to the point that runoff occurs will be avoided. WETLANDS • Identify sources of sediment and other pollutants that can affect the quality of storm water discharges. • Under no conditions will soil or other material be intentionally washed into storm drainage systems, drainages, or wetlands. • Focus on controlling erosion rather than controlling sedimentation. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -8 Best Management Practices March 2000e • All staging areas for wetland crossings will be kept at least 150 feet away from the wetland edge, when possible. • No refueling or servicing will be done within a wetland buffer. Absorbent material or drip pans will be placed underneath the equipment to contain leaks or spills. • Construction matting will be used for work in all saturated or inundated wetlands (required to get a Nationwide 12 Corps Permit). • Wetland contours will be restored to original conditions to prevent any damming of water flow across the wetland. If the original contours were irregular (e.g., hummocks), the restoration should not provide an unnatural watercourse that causes the area to dewater, thereby disrupting the natural wetland hydrology. • All handholes will be located outside of wetland areas wherever possible. • No activity will substantially disrupt the movement of those species of aquatic life indigenous to the waterbody. • Crossing of wetland areas by construction equipment or vehicles solely for the purpose of accessing other parts of the project construction right -of -way will be prohibited unless the only means of access is through the wetland. • If standing water or saturated soils are present, the contractor will use wide -track or balloon -tire equipment or operate normal equipment on equipment pads to perform the necessary construction activities. • All timber bridges, fords, culverts, and prefabricated equipment pads will be removed on completion of any construction activities. • During construction, will directionally drill all perennial/intermittent/seasonal drainages that support sensitive resources and have flowing water at the time of construction. (The environmental monitor will determine which drainages meet the criteria.) • Locate boring areas at least as far as jurisdictional requirements stipulate from the water's edge with a temporary work space on each side of the channel for equipment and staging. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix C C -9 Best Management Practices March 2000e WETLAND AND STREAM BUFFER WIDTHS PER JURISDICTION The following tables detail the stream and wetland buffer widths as required by each jurisdiction within the ROW. Each jurisdiction has unique wetland and stream categories. Associated with these categories are buffers which extend landward from either the ordinary high water mark of a stream, or the wetland/upland edge. A Wetland and Stream Assessment Report has been prepared by Williams for the ROW within each jurisdiction. Please refer to the individual reports for complete descriptions of each wetland and stream crossing, as well as discussion of the wetland and stream classification systems unique to each jurisdiction.

The 1987 manual is applied by the U.S. Army Corps of Engineers (Corps). This document represents an interagency effort whereby the U.S. Fish and Wildlife Service (USFWS), U.S. Soil Conservation Service (SCS), U.S. Army Corps of Engineers (Corps), and the U.S. Environmental Protection Agency (EPA) present a unified approach to wetland delineation. For regulatory purposes, the federal agencies define wetlands as follows: Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. The methodology for wetland delineation requires examination of three wetland parameters: soils, hydrology, and vegetation. For an area to be considered a wetland, a positive indicator for all three of these parameters must be present. WETLAND HYDROLOGY Areas possessing wetland hydrology are inundated either permanently or periodically, or the soil is saturated to within 1 foot of the surface for a week or more during the growing season. Direct observations of hydrology, including ponding and soil saturation, may be limited during the dry season or may be misleading during the winter rainy season. However, indicators may be present throughout the year that confirm the presence of wetland hydrology during the growing season. Indicators include water - stained leaves, oxidized root channels associated with living roots and rhizomes, visible sediment deposits, and exposed mud. In areas where no positive indicators of wetland hydrology are observed, but positive wetland indicators are present for soils and vegetation, wetland hydrology may be assumed to be present. HYDROPHYTIC VEGETATION Hydrophytic plants are those plants adapted to life in water, soil, or on a substrate that at least periodically lacks oxygen. Commonly occurring plant species have been assigned a plant indicator status by the USFWS based on their frequency of occurrence in wetlands. Plant indicator status categories are described in Table 1. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington E -1 Appendix E Summary of Federal Wetland Delineation Methodology March 2000e Table 1. Plant Species Wetland Indicator Categories Estimated Indicator Probability In Category Occurrence Wetland OBL Obligate. Occur almost always under natural conditions in wetlands. >99% FACW Facultative wetland. Usually occur in wetlands, but occasionally found 67 -99% in nonwetlands. FAC Facultative. Equally likely to occur in wetlands or nonwetlands. 34 -66% FACU Facultative upland. Usually occur in nonwetlands, but occasionally 1 -33% found in wetlands. UPL Upland. May occur in wetlands in another region, but occur almost <1% always under natural conditions in nonwetlands in this region (9). Source: National List of Plant Species that Occur in Wetlands: Northwest Region (Reed 1988). For a vegetation community to be considered hydrophytic, 50% or more of the dominant species in that area must be rated as facultative or wetter. In the case where half of the dominant species are hydrophytic and half are non - hydrophytic (upland), the determination is made based on the total percent areal coverage of each of the two groups. For example, if more than 50% of the total areal coverage is comprised of hydrophytic plants, the community is determined to be hydrophytic. HYDRIC SOILS Hydric (wetland) soils are defined as those soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic (wetland) vegetation. Hydric indicators include low soil chroma, mottles, gleying, and high organic content. Chroma is a measure of the intensity of grayness of the soil color. A chroma of 1, occurring with or without mottles, or a chroma of 2, occurring with mottles, is considered to be low and an indicator of hydric soils. Mottles are spots or blotches of contrasting color occurring within the soil matrix. Gleyed soils are predominantly neutral gray in color. Soils are considered to be organic if at least 18 inches of the upper part of the soil profile contains organic material or if the soil consists of organic material resting on bedrock. Soils are sampled with a hand -held soil auger and examined for hydric indicators. Observed soil characteristics are compared to the SCS descriptions of mapped soils (Local soil survey) to either confirm the mapping or determine if an inclusion is present. Most soils mapped by the SCS include areas of other soils (inclusions) that may make up from 2% to 50% of that unit. Williams Communications, Inc. Fiber Optic Line Installation Project Portland, Oregon to Seattle, Washington Appendix E E -2 Summary of Federal Welland Delineation Methodology March 2000e WETLAND BOUNDARY DETERMINATION An overall assessment was made of the site. Plots were sampled and evaluated for the three wetland criteria: hydrology, vegetation, and soils. A wetland or upland determination was made for each plot. Sample plot data were recorded on data sheets. Wetland boundaries were determined based on plot determinations and visual observation of site characteristics. As per prior agreement with the local jurisdiction, all wetlands were delineated and mapped on 1" = 200' aerial strip maps, and drawn on 7.5 minute USGS quadrangle maps. Only in Pierce County wetlands were delineated in the field with pink and black striped flagging affixed to vegetation at 25 -foot intervals. Blue and white striped flagging was used to identify plot locations. In areas where there was insufficient vegetation from which to hang flagging, orange - flagged wire stakes were used to identify the wetland boundary. The flagged wetland edge was surveyed by surveyor's name /must be surveyed by a professional surveyor. Williams Communications, Inc.

Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington vlll Biological Assessment Table of Contents March 2000 Section 1 Introduction This biological assessment (BA) has been prepared by Jones & Stokes for Williams Communications to evaluate the potential effects of the proposed action of a fiber optic line on special status (federally listed, proposed, or candidate threatened or endangered) species, and on designated or proposed critical habitat. (Critical habitat is specific area(s) within the geographical area occupied by the species, when it is listed, which contain the physical or biological features 1) essential to the conservation of the species and 2) which may require special management considerations or protection.) This evaluation presents "effects determinations" whether each species and/or habitat addressed is likely to be affected by the proposed action. This BA has been prepared pursuant to the final rules for interagency cooperation under the Endangered Species Act (50 CFR 402.12; June 3, 1986).

Z r Section 3 Proposed Action Williams Communications (Williams) proposes to install approximately 176 miles of fiber optic line from Portland, Oregon to Seattle, Washington. The fiber optic line installation is proposed to assist in meeting the growing demand for network capacity in the Pacific Northwest and to connect existing points of presence (POP sites) in Portland and Seattle. Installation of the line will expand the Pacific Northwest's national telecommunications access and enhance the is capability and reliability of the region's telecommunication infrastructure. Construction is proposed to begin June 2000, or upon receipt of the necessary authorizations from the applicable governing agencies. Construction is expected to take less than 6 months. Construction on some segments of the project ROW will be subject to various windows and conditions so that potential disturbance of sensitive species will be avoided (Tables 3 and 4). System testing will occur in December 2000 with commercial operation scheduled to begin January 1, 2001. Table 3.

This results in fewer environmental impacts than installing the fiber optic line along a non - previously disturbed route because the corridors have already been disturbed and are often actively maintained. These pre- existing cleared corridors are also likely to have established access for vehicles and construction equipment. Routes in road rights -of -way can also provide for future expansion if additional conduit is installed. However, routes in road rights -of -way do have a higher potential for future damage to the fiber optic line and are at a further disadvantage of requiring work around traffic operations. Installation within road rights -of -way is also less secure due to the typically high number of other utilities within the right -of -way. In some cases, the conduit and fiber optic line may be installed in the roadbed to avoid sensitive resources in the road shoulder or right -of -way margins. However, this technique will not be possible in very narrow roadbeds such as those installed on extremely steep slopes. Bridge attachments will be used at some stream crossings. Approximately 110 miles of the proposed fiber optic line will be installed within the existing Williams Pipeline (formerly Northwest Pipeline Corporations) right -of -way (ROW) easement (see the route map). The majority of the remaining line will be installed within already disturbed rights -of -way. Optical amplification (OP -AMP) stations and short sections of the fiber optic line will be installed outside these already disturbed rights -of -way. The project crosses mostly private land and small amounts of publicly owned land. In addition, it will cross Williams Communications, Inc.

The route will avoid 8 archeological resource sites and pass near approximately 40 historic structures. The numerous jurisdictions crossed will require approvals and permits from various federal, state, and local agencies. These permits address a variety of resource concerns, including water quality, wetlands, wildlife, fisheries, and land use. The Washington Department of Ecology is the lead agency for the State Environmental Policy Act (SEPA) process. The only jurisdiction it crosses in Oregon is the City of Portland. The Washington jurisdictions include the Port of Vancouver, the Cities of Vancouver, Castle Rock, Edgewood, Puyallup, Federal Way, Kent, SeaTac, Tukwila, and Seattle. The counties are Clark, Cowlitz, Lewis, Thurston, Pierce, and King. 3.2 FACILITIES 3.2.1 Overview The fiber optic line will consist of belowground and aboveground components. The belowground facilities are the fiber optic line, conduit, and manholes/handholes. The aboveground facilities are the line marker posts and OP -AMP stations. Fiber optic line, which is made up of bundled glass optical fibers wrapped in thin plastic sheathing, is inserted into the flexible, high- density polyethylene conduit. The conduit will have an outside diameter of 1.25 to 1.5 inches. The Portland and Seattle Laterals will consist of 6 to 20 conduits, while the Pipeline Lateral will have 6 to 9. Each conduit will accommodate one fiber optic line, which measures approximately 0.85 inch in diameter and is composed of 96 to 288 hair -thin glass fibers. Manholes and handholes are usually placed at intervals of 3 to 5 miles to serve as splice points and assist fiber optic line installation and maintenance. The fiber optic line is installed by using compressed air to blow it through the conduit. The handholes measure approximately 30 inches wide by 48 inches long and 24 inches tall, and will typically be buried 24 inches below grade. Generally, road shoulders or other easily accessible areas are the preferable locations for handholes. In some areas, at streets or OP -AMP stations, manholes measuring 6 feet wide by 4 feet tall may be installed. Only the manhole lids, which measure approximately 36 inches in diameter, will be visible at the surface and will be at grade. Manholes are typically used when the line is installed under city streets or other urban/developed areas. Placement of the handholes and manholes along the routes will avoid sensitive biological, archeological, and geological resources. Line marker posts will be located at approximately 700- to 1,000 -foot intervals to alert people of the presence of the fiber optic line. The posts are typically 3.5- inch - diameter round PVC posts with embossed lettering 4 feet aboveground. The proposed fiber optic line includes three OP -AMP stations, each of which will be located approximately every 44 miles along the route, and sited to avoid sensitive resources. An OP -AMP station boosts the signal. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland Oregon to Seattle. Washington 3 -7 Biological Assessment Section 3. Proposed Action March 2000 3.2.2 OP -AMP Stations The three stations will be placed on either 2.24 acre or 5 acre sites. Stations will consist of three to eight 12- by 30 -foot precast concrete buildings on concrete pads. The concrete pads, including concrete stoops, will cover approximately 3,850 square feet. The maximum height will be approximately 11 feet. Each building is shipped from the manufacturer equipped with one or two heating, ventilation, and air conditioning units to maintain a steady temperature for the electronic equipment housed inside the station. The unstaffed, locked facility will require commercial electric power and telephone service. Periodic maintenance will occur to assure that the facility is operating properly. A diesel - powered generator (maximum 255- horsepower) and aboveground and bermed fuel tank will be installed for emergency back -up use. More buildings could be added if network traffic levels required it. Williams will construct the stations on or near previously disturbed sites. In addition to t making construction easier, it will eliminate or minimize potential environmental impacts. t t; Stations will not be sited in areas that: • have not been surveyed, documented, and ensured clear of sensitive biological and cultural resources by Williams' environmental consultants; • are within a designated floodplain; • are adjacent to waterbodies, including wetlands, drainages, rivers, streams, or lakes; • are on sites with known contamination; or • are in areas that are designated as scenic. 3.2.3 Staging Areas and Access Roads Staging areas for construction equipment, materials, fuels, lubricants, and solvents will be established along the project ROW during construction to allow more efficient use and distribution of materials and equipment. Whenever possible, staging areas will be located on private lands in existing contractor yards; existing commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or level areas where grading and vegetation clearing are not required. The construction contractor, as needed, before and/or during construction typically selects staging areas. Each area is expected to be 4 to 5 acres in size. This practice is consistent with construction methods used throughout the United States. To ensure that sensitive environmental resources are adequately protected or are avoided, the locations of staging areas will be determined in consultation with environmental resource specialists. Since fuels, lubricants, and solvents will be stored in staging areas, all staging areas will be located at least 150 feet away from sensitive stream/drainages. Access to the project ROW will be by existing access roads or previously disturbed areas. While no new access roads will be created, some existing roads may require minimal repairs to Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 3 -8 Biological Assessment Section 3. Proposed .action Alarch 2000 1 make them usable for construction. After completion of the line installation, access roads will be repaired and/or improved, if necessary, to prevent future erosion. Access roads will not selected until the early stages of construction planning. Selection of access roads will be determined after consultation with qualified biologists and archeologists to ensure that sensitive environmental resources are adequately protected or avoided. Since not all of the rights -of -way follow improved roads and some areas lack bridges, construction equipment may need to be transported through some streams (i.e. Type 5 waters). In many cases, roads already cross small or ephemeral streams along the existing right -of -way to be used by Williams. In most of these instances the stream banks are gradually sloped and water flows will be nonexistent to sufficiently low to allow vehicles to drive through the channel with negligible impact to the channel. In some cases, these access points may need to be modified to accommodate construction equipment by placing clean drain rock, cutting fords, or installing temporary culverts. Such modifications will be permitted through the appropriate agencies, and will not occur in streams supporting sensitive resources. 3.3 CONSTRUCTION This section begins with a discussion of the construction management and environmental management response plan. Next is an explanation of the spread crews, followed by a description of the conduit and line installation. This section concludes with a discussion of the construction of the OP -AMP stations. 3.3.1 Construction Management and Environmental Management Response Plan The construction management and environmental management response plan consists of two components, personnel and training, which are discussed below. 3.3.2 Personnel A proper management structure, adequate training of field personnel, an environmental training program, and the ability to respond to changing circumstances are critical components to the success of the proposed fiber optic line. Training classes for the contractor and construction crews will be held covering issues such as environmental protection, safety, spill prevention and response, fire prevention and management, and proper management of stormwater runoff. The field management structure will include engineering, construction, and environmental personnel such as spread superintendents, spread supervisors, contract compliance inspectors, environmental resource coordinators, and biological, archeological, and geotechnical support. The roles and responsibilities of each onsite representative will be clearly understood and communicated during the training program and are summarized below. The contractor and Williams' spread superintendents will be onsite to address engineering questions, make field decisions, and coordinate with permitting agencies. The Williams Commnications, Inc.

The superintendents also have the ability to shut down the construction operations in case of environmental noncompliance, emergencies, safety issues, and disputes with the construction contractor. Williams' spread supervisor will be onsite for each contractor to oversee the individual contract compliance inspectors and work with the contractor to resolve field conflicts. The spread supervisor will report directly to the construction superintendent and also perform most of the administrative duties. The spread supervisor will communicate daily all construction activities related to compliance, safety, and administration. Contract compliance inspectors will be assigned to each construction crew to observe their work. Where crews work in the same area, one inspector could, monitor more than one crew. The inspector will monitor the environmental resource concerns and check implementation of the erosion protection measures. The contract compliance inspector will be trained on environmental issues that may be encountered during the construction project and will have immediate access to biologists, archeologists, and geologists. The environmental resource coordinator will work with the contract compliance inspector and biologists, archeologists, geologists and agencies, and the engineering and construction representatives to resolve conflicts and coordinate resource avoidance and protection. The ' environmental resource coordinator will patrol the construction site periodically to help monitor implementation of the resource protection measures. Biologists, archeologists, and geologists will be onsite during construction. They will locate and stake sensitive resources in the field, note the resources on the construction drawings, and advise the contractor regarding the necessary protection methods. They will also coordinate with monitors from the appropriate agencies. Monitoring activities associated with construction will proceed as follows: ■ locate all sensitive resources, construction methods, and avoidance measures or mitigation measures on the construction drawings; • acquire permits and approvals from governing agencies; ■ prepare traffic control plans, as necessary; • conduct preconstruction wildlife surveys in predetermined suitable habitat areas; • stake and flag resources as stipulated in the environmental documentation and from results of field surveys conducted for each project route; • prepare the rights -of -way and install sedimentation control measures where needed; • install conduit, the fiber optic line, and associated facilities; • restore the rights -of -way and install erosion control measures; Williams Communications, Inc.

Proposed Action March 2000 N`. • apply seed and mulch as specified in the SWPPP and reclamation plans; • monitor erosion control; and, • monitor success of mitigation. All levels of field management and construction personnel will be informed about environmental protection and the necessity of compliance. Training will take place at the Williams engineering level and at the contractor level. Appropriate personnel from the regulatory agencies will be invited. f-4 3.3.3 Training Ps) Training seminars led by project managers and resource experts will be held before construction to explain and educate construction supervisors and managers about the following: • the need for and importance of resource avoidance and protection; • resource mapping format and interpretation of construction drawings; ▪ resource protection staking methods; • the construction process as it relates to required mitigation measures; f-A• • roles and responsibilities; and, • the project management structure and contacts. .614 All contract compliance inspectors will be required to complete an inspector training t:.. class. These classes will cover issues such as the environmental issues mentioned above, resource mapping and construction drawing interpretation, roles and responsibilities, and site +:,R safety. The contractor team will include the job superintendent, crew foremen, and ,;. crewmembers. The training and education will take place through several processes beginning with the preconstruction meetings and ending with training classes just before construction activities begin. Meetings with the contractor will be held prior to construction and will include discussions about the issues listed above. They will be used as an opportunity to reinforce the need for and importance of compliance with environmental resource avoidance and protection measures. The spread superintendents, supervisors, contract compliance inspectors, and environmental coordinators will conduct meetings regularly with the contractors' superintendents and foremen to coordinate the construction and mitigation processes. The contractors' foremen will be responsible for transmitting, on a weekly basis, the information discussed in the preconstruction meetings to the crewmembers. Williams Communications. Inc.

Proposed Action March 2000 { —J 3.3.3.1 Spread Crews Discusseti below are the number and types of crews associated with each spread and the flow of construction activities along the project ROWs. The actual number and composition of the workforces may vary with conditions at the time of construction. The contractor is responsible for determining the most efficient methods for completing the work within the parameters given. Before beginning construction, Williams and the onsite biological monitor will review the rights -of -way to determine the most appropriate access method for each stream and will note these methods on the construction drawings. Williams anticipates hiring multiple contractors depending on the amount of time available to install the conduit and line and construct associated facilities. Each spread will consist of the following 6- to 12- person crews: • Preparation Crew — The preparation crews will prepare the right -of -way for construction by placing temporary gates in fences, clearing vegetation where necessary, and repairing erosion problems on existing roads to provide access. • Conduit and Line Installation Crew — The conduit and line installation crews will install the conduit and line. • OP -AMP Station Crew — The OP -AMP station crew will prepare the site and construct the stations. • Cleanup Crew — The cleanup crews will perform final cleanup of the right -of -way, restoring preinstallation ground contours, installing erosion protection measures (e.g., erosion control blankets), restoring affected stream channels and removing fences and gates. Clean up will be ongoing and will take place immediately after all work is completed per segment. • Seeding Crew — The seeding crews will apply seed and mulch where necessary. 3.3.4 Conduit and Fiber Optic Line Installation Conduit and line installation will not threaten overhead utilities due to the amount of vertical clearance under the utilities. For underground facilities, the "One Call" utility location services will be contacted a minimum of 48 hours before construction. The "One Call" services will alert all registered utilities about the scheduled construction activities, allowing the utilities to identify the location of their underground facilities and thus greatly reduce the possibility of interruptions in utility services. In many instances, the project will cross private property. Landowners, with whom easements will have already been obtained, will be contacted before construction. Right -of -way personnel will be available to answer landowners' questions and to negotiate any cleanup or restoration issues that may arise. Williams will negotiate with the owners and tenants regarding any project - related crop losses. The timing of construction will, wherever practicable, be during Williams Communications, Inc.

Any trenching activities in farmland will be done according to the above - mentioned procedures. Three methods will be used to bury the conduit, based on several factors, including site conditions. The methods of plowing, trenching, and drilling are described below. Plowing installation uses a Cat with a cable reel in front and a plow blade in back (See typical(s)). As the Cat moves, it simultaneously furrows the soil and installs the conduit. The plowing Cat weighs approximately 43 tons. The plow furrow will typically be one foot wide and 48 inches deep. In some instances, the soil may be pre -ripped by a tractor in front of the plow. Ripping is a technique in which a slit is made in the surface of the soil to loosen it. The construction corridor is usually up to 30 feet wide. Up to 2 miles of plowing can be completed per spread, per day. Trenched installations will predominantly be used at tie -in points to connect conduit at handholes and manholes. The trenches will be 4 to 6 feet wide, 8 to 10 feet long, and 48 inches deep. Other narrow trenching will be done in certain metropolitan areas where drilling or plowing is not feasible. Trenching is typically done with a rubber -tired backhoe or an excavator, using an 18- to 24 -inch bucket. A backhoe weighs approximately 8 tons. If conditions do not allow for small isolated areas, such as handholes or assist points, to be backfilled at the end of each day, appropriate safety, erosion, and wildlife control features will be installed. A 30 -fdot wide right -of -way is needed where trenching is to take place, of which ten feet is required for trackedlrubber -tired equipment and vehicular construction traffic. The construction corridors will typically be confined to within the existing rights -of -way. Directional drilling will be used in various locations along the ROW to cross -areas where surface disturbance must be avoided (e.g., crossing railroads, highways, rivers, sensitive streams, and wetlands). Directional drill lengths could range from less than 100 feet to 750 feet. To complete the drill, a work area is established on each side of the crossing (see typical(s)). For river, stream, and wetland crossings, the work areas, will be located at distances stipulated by the local jurisdictional buffer ordinance distance from the bank or edge of the resource. One work area contains the "pilot hole" and drilling equipment. The other work area contains the "receiving hole" where the drill bit emerges. Depending on the length of the drill, the drill entry areas range from 2 feet by 2 feet to 4 feet by 4 feet. Drilling equipment most suitable for site - specific conditions will be used for each drill. Silt fences, straw bails, and other erosion control measures will be installed around these work areas. Approximately 500 feet of drilling could be completed per day, per drill rig. During the drilling process a bentonite slurry typically is pumped through the drill hole to help lubricate the drill bit, prevent the drill tunnel from collapsing, and carry drill cuttings to the surface. Bentonite is a naturally occurring clay known for its hydrophilic characteristics. The slurry is pumped through the drill hole, collected at the surface, passed through machinery to remove the drill cuttings, and then recirculated through the hole. The slurry may be stored in tanks at the drill site when not in use. Any excess slurry remaining after the drill is complete will be removed from the site and either reused by the drilling contractor or disposed of at an appropriate facility.

All efforts will be made to complete directional drills at sufficient depths to prevent bentonite releases. Drilling under roads will be at a depth of at least 5 feet, while under flowing streams, the minimum depth will be 10 feet. While plowing will be used at some stream crossings (i.e. Type 5 Streams), flowing streams with sensitive resources (e.g., high -value habitat for threatened or endangered species) will be crossed by attaching the conduit to an existing bridge or by drilling under the stream (see typical(s)). The work areas will be located outside the stream area. No in -water trenching is proposed in flowing streams with sensitive resources located at or downstream of the crossing. The drill entry site for the Columbia River will be located on Port of Vancouver property. The exit site will be in Kelly Point Park in Portland. The work areas on each end of the drill will be approximately 100 feet wide and 300 feet long. The entry area will be a maximum of 15 feet by 15 feet and one foot deep. The drill will be approximately 4,300 feet long. The conduits, which will be in a 10 -inch steel casing, will be at least 20 feet below the river bottom. The drilling operation will take approximately two weeks. After completion of the drilling, the work areas will be refilled with the same material taken out and the work area will be restored to its pre - construction condition. 3.3.5 OP -AMP Stations The following is a description of the construction process of the OP -AMP stations: • grade site level; • fence off the site; • hook -up electrical service; • gravel site; • install concrete pads; • place precast buildings on pads; and, • install electronic equipment, and other appurtenances. 3.4 OPERATIONS Operation activities will consist of maintaining erosion control measures, repairing or replacing line conduit due to of storm damage or other emergencies, and routine maintenance of the OP -AMP stations. In most emergency situations, access to inspect damaged areas will be accomplished via helicopter or public roads. After installation, access for maintenance will also be by existing access roads to the right -of -way. Williams Communications, Inc.

O z • :.4 3.5 MITIGATION Williams will be responsible for implementing the mitigation measures identified in this document and other measures that will be determined by the associated permitting agencies and through the permitting process. The general mitigation measures that are known at the time of the preparation of this document are described below. The measures have been developed and designed as part of the proposed fiber optic line to avoid or reduce potential significant impacts to less - than- significant levels. 3.5.1 Avoidance Measures Sensitive resources will be avoided through various means identified during the project design phase. However, there also will be avoidance measures occurring in the field during construction as a result of preconstruction surveys or at the direction of construction inspectors. If required, the construction technique will be coordinated through a monitoring resource specialist familiar with the resource issue being avoided. Typical avoidance measures include minor rerouting of the line around the sensitive resource within the disturbed right -of -way, drilling under the resource, or attaching the line to an existing bridge. Significant impacts will be avoided at sensitive drainages, including perennial stream crossings or streams that are flowing at the time of construction and have sensitive resources located at or downstream of the crossing. At all streams that provide important habitat, contribute significantly to water quality, or support sensitive or listed aquatic species, conduit and the fiber optic line will be installed either by drilling under the drainage or by attaching the line to existing bridges. In many situations, these methods will also be used for wetlands. The avoidance methods for each sensitive resource will be shown on the construction drawings. 3.5.2 Best Management Practices Best management practices detailed in the Stormwater Pollution Prevention Plan (SWPPP) will be implemented. Spill prevention countermeasures contained in the SWPPP (required under the NPDES permit) are designed to prevent or minimize the risk of bentonite entering surface waters during directional drilling. Although bentonite releases rarely occur, bentonite can reach the ground surface and enter surface waters if the drill encounters a rock fracture during high - pressure drilling operations conducted over long distances. However, the risk of bentonite reaching the surface or surface waters is minimized because contractors typically use the smallest practicable drilling equipment which injects the bentonite at lower pressures. Erosion is the process of soil particles being displaced and transported by wind or water. Conduit and fiber optic line installation will disturb soil and vegetation, exposing sites to possible erosion. The hazard of erosion is increased by the presence of steep slopes, concentrated or channelized water flow, and high streamflows. The best management practices that will be undertaken in accordance with all applicable regulations and standards will be Williams Communications, Inc.

Erosion and sediment control measures are used to reduce the amount of soil that is carried off a land area, and to control the discharge of soil particles that are carried away. The following standard erosion and sediment control measures and practices will be used during and z after construction to control accelerated soil erosion and sedimentation. i E-= 1— Z. • minimize site disturbance; D • perform initial cleanup; _1 0 ■ compact subsurface backll material; u) W f • leave topsoil in roughened condition, except in road shoulders; L11 = ■ install trench plugs; co u. • construct water bars;. • install baffle boards; ■ where necessary, armor bank slopes with riprap; • perform seeding and mulching; = a • install erosion control blankets; F— _ ■ install silt fencing and straw bale dikes; and, z f". • conduct periodic maintenance of erosion and sediment control measures. Z F L1.1 ai Ca The most basic way to avoid erosion is to minimize site disturbance. Williams' v contractors will be directed at the environmental training program to implement practices that o —' minimize site disturbance to ensure impacts are avoided or reduced to less - than- significant w ..1 levels. These measures (described below) are routinely implemented in the construction industry � v and have been proven successful for similar buried telecommunication system installations. The u_ O contractors will be directed to: u.i U= 0 H. z ■ remove only the vegetation that is absolutely necessary to remove; ■ avoid off -road vehicle use; • avoid all sensitive resource areas; ■ avoid excessive trips along the right -of -way or access or maintenance roads; and, • instruct all personnel of the concepts of stormwater pollution prevention to ensure that all are conscious of how their actions affect the potential for erosion and sedimentation. Williams' inspectors will be onsite during all construction activities and will reinforce the importance of confining all vehicular traffic to the existing right -of -way and maintenance and access roads. Williams' contractors will be directed to perform initial site cleanup immediately following conduit and fiber optic line installation. Initial cleanup includes removing debris and spoils and restoring original contours. Initial cleanup performed as part of the construction will contribute significantly to the overall site stability and will make final cleanup easier. The site Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle. Washington 3 -16 Biological Assessment Section 3. Proposed Action March 2000 r ci will immediately begin to stabilize naturally with little additional disturbance during final cleanup. A site that is not initially cleaned up is more susceptible to erosion. Proper compaction of subsurface soil serves as an erosion control measure. Uncompacted plow or trench furrows are susceptible to subsurface erosion through the migration of surface and subsurface water. Proper compaction of the subsurface material and plow furrows is necessary to help prevent surface and subsurface migration of water along the plow or trench furrow and to prevent trench settlement. The reapplied topsoil in the right -of -way will be left in roughened condition to facilitate the establishment of vegetation and reduce the potential for erosion. A trench plug is a permanent mechanical erosion control measure consisting of soil - filled burlap bags placed in the excavated trench before backfilling. Trench plugs serve to control erosion by stopping subsurface water flow. Trench plugs are placed in the trench at regular intervals along areas with steep slopes. The spacing is determined by slope grade, topography, and soil characteristics. Trench plugs will be installed as shown on the construction drawings. Seeding consists of sowing soil - stabilizing grasses on areas disturbed by construction activities except cropland and areas surfaced with pavement or gravel. Vegetation serves both erosion and sedimentation control. The root structure of the vegetation holds soil in place to resist erosion. Grasses slow the flow of surface water, allowing suspended particles to settle. Mulch, typically consisting of wheat straw, is usually applied over the seed to protect the soil surface until the grasses become established. 3.5.3 Steep Slopes On steep slopes that are susceptible to erosion, erosion control blankets will be installed to hold seed and soil in place until vegetation is established. The onsite- spread supervisors will determine where blankets are necessary. Silt fences and straw bale dikes will be installed, as needed, at the toe of slopes below disturbed areas to prevent sediment from reaching streams and wetlands. These sediment barriers retain sediment while allowing water to seep through. Straw bale dikes may also be installed around drop inlets and in small swales to retain sediment. Water bars are an erosion control measure that function by slowing runoff rates and diverging runoff from the disturbed area. A water bar consists of an earthen berm placed along the ground across the disturbed area of construction. Water bars are left in place and become permanent erosion control measures. A baffle board is an erosion control measure consisting of pressure- treated 2- by 12 -foot boards and 4- inch - diameter wooden posts. Baffle boards work like water bars but are used on slopes too steep for water bars. However, baffle boards cannot be used on roads. Board spacing is determined by slope grade, topography, and soil type. The contractor will install baffle boards, as necessary, during the final cleanup stage of installation. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington 3 -17 Biological Assessment Section 3. Proposed Action March 1000 Riprap is an established method of permanent erosion control. Riprap will be used for slope stabilization, water energy dissipation, and armoring of stream banks. Riprap will be used only on stream banks where the existing channel consists of rock or in highly erodible drainages that lack woody riparian vegetation. Armoring drainage banks with riprap may be used on rare occasions. Permanent erosion control measures are currently in place along much of the existing right -of -way as a result of previous facility construction. The effectiveness of these measures will be evaluated before construction. Any existing measures will be restored, as required and left in place after the installation of the fiber optic line is complete. The spread superintendent following construction activities to determine where additional erosion control measures are necessary will also assess the right -of -way. 3.5.4 Reclamation Right -of -way reclamation is the final step in the installation process. The short-term objectives of reclamation are to control accelerated erosion and sedimentation, and to minimize impacts on adjacent waters, land uses, and other sensitive resources. Properly executed construction practices and timely progress will mitigate temporary and short-term construction impacts. Long -term objectives include erosion and sedimentation control, as well as reclamation of topography to preinstallation conditions. The reclamation effort will focus on the following objectives: • topsoil salvage, storage, and replacement; • reclamation of right -of -way and associated maintenance and access roads; • reclamation of drainage and wetland crossings; and, • monitoring to ensure long -term success. In most instances, access and maintenance roads were constructed when the original utility, pipeline, or railroad facilities were constructed. These existing roads provide access to the rights -of -way from other public or private roads. Minimal grading of these roads may be necessary in isolated areas to prepare them for use during construction. In addition to paved state and county roads, the access and maintenance roads may also include improved and low -use unimproved secondary roads. Following construction, the right - of -way or disturbed areas will be graded to preinstallation grades and contours. Little grading is expected because no excavation activities will occur on the roads except to correct existing erosion problems. The following soil handling methods will be implemented to promote successful restoration: • any refuse and debris will be removed from the compacted trench or excavation before topsoil is replaced, and Williams Communications. Inc. Fiber Optic Line System Installation Project Portland. Oregon to Seattle, Washington 3 -18 Biological Assessment Section 3. Proposed Action March 2000 • the length of time topsoil is stored will be minimized based upon the pace of the installation activities (normally, topsoil removal and respreading activities will occur on the same day). When the crossing is completed, the beds and banks of the drainages will be restored in a manner that allows vegetation to reestablish to its preinstallation conditions. Where necessary, a biodegradable erosion control blanket or riprap will be used to protect and stabilize streambanks. Riprap will be used only where existing stream channels consist of rock armoring and lack woody riparian vegetation. Erosion control blankets will be used on steep slopes or where the soils otherwise have a high erosion potential. The type and locations for these measures will be determined in the field by the spread supervisor with input by other appropriate personnel. 3.6 SAFETY 3.6.1 Traffic Control The ROW crosses land used by other entities, including public roads, utilities, railroads, and private property. Williams, in coordination with affected jurisdictions, will develop and implement a traffic control plan for installation activities within public road and highway rights -of -way to reduce construction- related effects on traffic and circulation patterns during the construction period. All construction activities will follow the standard construction specifications of the affected jurisdictions. The traffic control plan may include the following actions: • coordinate with the affected jurisdictions on construction hours of operation and road closures, if any, to minimize impacts; • follow guidelines of the affected jurisdiction, if any, for temporary road closures caused by construction activities; • limit lane closures during peak commuting hours to the extent possible; • install traffic control devices as specified in the appropriate manuals; and, ▪ consult with emergency service providers and develop an emergency access plan for emergency vehicles moving through the construction zone. 3.6.2 Spill Prevention and Pollution Control The equipment used for the proposed fiber optic line will need periodic maintenance and refueling. These activities will be accomplished responsibly, using the prescribed spill prevention countermeasures described below.

These sources included local critical ordinances, Department of Natural Resources' stream type maps, strip maps of Williams Pipeline Corporation's ROW with overlaid survey data on aerial photographs (1992), aerial photographs of the ROW (1999 and 2000), USGS topographic maps, National Wetland Inventory maps, Federal Emergency Management Agency floodplain maps, Natural Resources Conservation Service soil surveys, and the USGS Determination of Upstream Boundaries on Western Washington Streams and Rivers under the Requirements of the Shoreline Management Act. Field surveys were conducted to delineate, map, and characterize waters of the United States, including wetlands, subject to regulation under Section 404 of the Clean Water Act. Existing available information was gathered and reviewed to determine the location and types of fisheries and wildlife resources that could exist within the ROW. These sources included WDFW Priority Species Map and USFWS and NMFS threatened and endangered species account lists. In addition, the Washington Natural Heritage Program rare plants and high quality habitats database was reviewed to determine the location and types of sensitive vegetation species and high quality habitats that could exist within the ROW. Field surveys were conducted to evaluate suitable habitat for threatened, endangered, candidate, and other special - status plant, wildlife, and fish species that were identified as having the potential to exist within the ROW. Wetland, wildlife and fisheries biologists conducted numerous surveys between June 8, 1999 and February 10, 2000. Williams Communications, Inc.

The entire ROW falls within the Puget/Willamette Lowland geomorphic province. 5.1.1 City of Portland The fiber optic line would be drilled under the Columbia River from the Port of Vancouver, Washington, to Kelley Point Park in Portland, Oregon. The ROW in the City of Portland starts at the Portland POP site located at 707 SW Washington Street. The route leaves the POP site from the northwest corner of the building at Stark Street and Park Avenue. On the south side of Stark Street, the ROW angles to the north side of Stark Street to the intersection of Stark Street and 9th Avenue. The ROW then moves right onto 9th Avenue and left onto NW Front Avenue (also called NW Naito Parkway). Next, the ROW follows the Fremont Bridge (also Highway 30 and Interstate 405) across the Willamette River (bore upstream of bridge, exits bore between Loring Street and Union Pacific Railroad (UPRR) tracks). The ROW then moves west on Nesmith Avenue to North River Road, and right onto North River Street. The ROW follows North River Street to the UPRR tracks along Willamette River following the UPRR tracks and left onto North Lombard Street. At North Lombard Street, the ROW moves left onto North Time Oil Road (Alternative: Take North Lombard Street to North Rivergate Boulevard, left on North Rivergate Boulevard/North Lombard Street) and right at UPRR tracks. The ROW then follows the UPRR tracks to the Kelley Point Park drill site. The majority of the ROW in Oregon is located in industrial areas either along paved roads or within the railroad ROW, which has been cleared of most native vegetation. The three wetlands within this alignment are dominated by reed canarygrass and willow species. Kelley Point Park holds mature black cottonwood trees but is also dominated by Himalayan blackberry and other invasive or exotic species. 5.1.2 Clark County In southern Clark County the project ROW follows the SR -501 and SR -502 right -of -way, which is approximately 30 feet wide and 12 miles long. In northern Clark County, the project ROW lies within the Williams Pipeline ROW, which is approximately 75 feet wide and 11 miles long. The ROW continues within the Williams Pipeline ROW through Cowlitz, Lewis, Thurston, and southern Pierce counties. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington ,.�a :fi MNrcw i4,4/A41,60,0!: 5 -1 Biological Assessment Section S. Setting March 2000 In Clark County, the project ROW passes through the mainstem lower Columbia River and the lower Lewis River watersheds. Land uses in the area include rural development, agriculture, and forestry. Topography is dominated by gently rolling alluvial terraces originally deposited by the Columbia River and now mostly covered by moderately deep, moderately well - drained soils interspersed with patches of more hydric soil types. Elevations range from 0 to 800 feet above sea level. The ROWs for SR -501, SR -502, and the Williams Pipeline are maintained and cleared of most shrub and tree vegetation for highway or pipeline access purposes, and to reduce the chance of damage to the pipeline associated with tree roots. Highway construction and ROW maintenance have altered the local hydrology, disturbed soils, and created wetlands in areas that were previously upland. Continued disturbance of these areas has introduced a variety of invasive and/or exotic plant species, including bull thistle, trailing blackberry, reed canarygrass, red and white clovers, and Himalayan blackberry (scientific names of all plants are presented in Table 6).

Herbaceous communities generally dominate within the ROW. Common wetland species consist of reed canarygrass, creeping buttercup, cattail, and several species of sedge and rush. Upland herbaceous species often found include tall fescue, Canada thistle, bull thistle, and several species of grass. Wetland shrub species within the ROW are limited to Douglas' spirea and some willow species, while common upland species include Himalayan blackberry, trailing blackberry, and rose species. Very few mature tree species are found within the ROW. Common saplings identified include Oregon ash and black cottonwood. Dominant herbaceous vegetation adjacent to the highway ROW generally includes, Himalayan blackberry, trailing blackberry, reed canarygrass, Canada thistle, and bull thistle. Forested communities are often dominated by big -leaf maple, red alder, and black cottonwood. Other non - dominant tree species include western red cedar and Douglas fir. The Williams Pipeline ROW has been cleared of most woody vegetation. For most of its length, the soils have been trenched for pipeline installation. In many instances, the trenched soils were deposited on the downslope side of the trench, altering local hydrology and creating wetlands within characteristically upland habitats. Pipeline construction disturbances, along with the predominance of agricultural and grazing activities within the project ROW, have allowed the invasion of many weedy and/or non - native plant species. These commonly include bull thistle, Scots broom, reed canarygrass, Himalayan blackberry, evergreen blackberry, and Douglas spirea. Common upland species in the ROW include herbaceous species such as meadow fescue, tall fescue, common velvetgrass, various species of thistle, sword fern, bracken Williams Communications, Inc.

Common wetland herbaceous species include reed canarygrass, small - fruited bulrush, creeping buttercup, cattail, red top, bluegrass species, and a variety of sedges and rushes. Wetland shrub species are generally limited to Douglas spirea and salmonberry. Although mature trees are removed within the ROW during maintenance activities, common saplings include red alder, Douglas-fir, big -leaf maple, and Oregon ash. Adjacent to the ROW, the most common plant communities are Douglas fir forest, red alder/big -leaf maple forest, and Himalayan blackberry/meadow fescue shrub /grassland. In a few areas, Garry oak woodland adjoins to the pipeline corridor, and there are some floodplain forested wetlands dominated by Oregon ash. 5.1.3 Cowlitz County The project ROW in Cowlitz County follows the Williams Pipeline ROW, and lies from 0.5 to 2.5 miles east of Interstate 5. Land uses are primarily agricultural, forestry, and rural residential. The ROW includes portions of (from south to north) the Lewis, Kalama, Coweeman, and Toutle River watersheds. The Lewis and Kalama rivers are tributary to the Columbia, while the Coweeman and Toutle rivers are tributaries to the Cowlitz River. The terrain has moderate relief with elevations ranging from about 10 feet above sea level along the Coweeman River floodplain to approximately 1,500 feet on the west side of Green Mountain. Vegetation communities within the ROW are dominated in upland areas by meadow fescue, meadow foxtail, rough bluegrass, Himalayan blackberry, salmonberry, and Scots broom. In wetland areas, dominant species include reed canarygrass, common velvetgrass, soft rush, and creeping buttercup. Outside of the ROW, more than half of the land is forested, of which 25% is early seral (shrubland). These forests are primarily composed of Douglas fir, Western red cedar and red alder. The remaining land is nonforest, primarily grassland or pasture. The most common grasses are fescue and reed canarygrass. 5.1.4 Lewis County The project ROW in Lewis County also follows the Williams Pipeline ROW, roughly parallel to and east of Interstate 5. Land use is primarily agricultural and rural. The area includes portions of both the Cowlitz River and the Chehalis River watersheds. The broad, well - developed floodplains of these rivers are surrounded by low terraces and uplands of low to moderate relief. In the southern and central portions of the Lewis County ROW, elevations range from 80 to 200 feet with very low relief. In the northern portions, elevation ranges from 100 to 600 feet and the project ROW runs through moderately steep slopes dissected by numerous small streams. Vegetation is generally similar to that found farther south, with a few changes in species composition. Weedy and/or non - native plant species found within the ROW commonly include Himalayan blackberry, evergreen blackberry, trailing blackberry, Douglas spirea, Scots broom, bull thistle, meadow fescue, common velvetgrass, bird's foot trefoil, hop clover, reed canarygrass, and creeping buttercup. Within the ROW, common upland herbaceous species are meadow fescue, sweet vernalgrass, oxeye daisy, various thistles, giant horsetail, tall fescue, Williams Commnications, Inc.

Common upland shrub species include Scots broom, Himalayan blackberry, trailing blackberry, vine maple, various roses, and beaked hazelnut. Mature trees are customarily cut down within the ROW lest their root systems damage the pipeline, but common seedlings and saplings in the ROW include red alder, Douglas -fir, big - leaf maple, and Oregon ash. Common wetland herbaceous species within the ROW include reed canarygrass, creeping buttercup, meadow foxtail, common horsetail, slender - spiked mannagrass, soft rush, bluegrass species, small - fruited bulrush, and common cattail. Wetland shrub species within the ROW are generally limited to Douglas spirea and salmonberry, but some riparian wetlands support Sitka willow. Vegetation communities adjoining the ROW are in many places agricultural or residential, thus dominated by cultivated plants. Native plant communities adjacent to the project ROW are generally Douglas -fir /western red cedar forest, red alder/big -leaf maple forest, and Himalayan blackberry/meadow fescue shrub /grassland. The forest habitats, which border 60% of the ROW corridor, are generally young, with about 10% of the area covered by forests in a shrub stage (young clearcuts). About 35% of the ROW corridor is bordered by agricultural lands, chiefly pasture, and 4% is bordered by residential lands. Garry oak woodlands grow along 1% of the ROW corridor. 5.1.5 Thurston County The Williams Pipeline ROW crosses Thurston County from southwest to northeast, across land dominated by agricultural, rural, residential, and forest production land uses. The area includes portions of both the Chehalis River (including its tributaries, the Skookumchuck and Deschutes Rivers) and Nisqually River watersheds. Between the Skookumchuck and Deschutes rivers, the project ROW passes through moderately hilly terrain with elevations ranging from 400 to 1,300 feet. North from the Skookumchuck River to the Nisqually River (the Thurston/Pierce County line), the project ROW enters nearly flat terrain (a glacial outwash plain with extremely well- drained soils), with elevations varying from 300 to 400 feet. Upland vegetation communities within the ROW are dominated by meadow fescue, oxeye daisy, red alder (again, as seedlings and saplings), common velvetgrass, trailing blackberry, colonial bentgrass, hairy cat's -ear, and white clover. Wetland communities within the ROW are predominantly herbaceous, characterized by soft rush, reed canarygrass, common velvetgrass, and small - fruited bulrush; red alder is commonly present as seedlings or saplings, but is cleared from the ROW before it can grow to tree size. Most plant communities adjoining the ROW consist of cultivated plants, young Douglas -fir forest, or young red alder/big -leaf maple forest. Forest accounts for 60% of the ROW corridor, pasture and other agricultural lands represent 25% of the corridor, residential lands occur on 10% of the corridor, and the remaining 5% is evenly split between aspen forest and Garry oak woodland, both of which are classified as sensitive native plant habitats. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington d 5 -5 Biological Assessment Section 5. Setting March 2000 F 5.1.6 Pierce County The project ROW crosses Pierce County from southwest to northeast across land dominated by military (Fort Lewis), agricultural, and suburban residential land uses. Portions of the ROW follow the Williams Pipeline corridor, while other portions follow county roads, but always remaining within existing cleared and maintained ROW. The ROW includes portions of the Nisqually and Puyallup river watersheds. The terrain has very little relief, consisting of glacial sediments including outwash and till. Elevations vary from approximately 100 feet at the Puyallup River crossing to approximately 400 feet on the highest glacial landforms. Upland vegetation communities within the ROW are dominated by Himalayan blackberry, seedlings and saplings of red alder, reed canarygrass, meadow fescue, colonial bentgrass, redtop, evergreen blackberry, Canada thistle, and white clover. Wetland vegetation communities within the ROW are dominated by reed canarygrass, seedlings and saplings of red alder, soft rush, Douglas spirea, redtop, creeping buttercup, common velvetgrass, water foxtail, and Sitka willow. Most plant communities adjoining the ROW consist of cultivated plants, including numerous hayfields, pastures, and a golf course. Dominant species adjoining the ROW include Douglas fir, red alder, Oregon ash, black cottonwood, Douglas spirea, and reed canarygrass. Depending upon final ROW selection, 2 to 3 miles of the ROW in the Fort Lewis area passes through native plant grasslands that have been heavily invaded by Scots broom. These are classified as sensitive habitat. An alternative ROW that largely avoids Fort Lewis by following county roads is bordered for 1 mile by native plant grassland and for several miles by late - successional Douglas fir forest, both of which are classified as sensitive habitats. In both cases, construction impacts will be confined to disturbed habitats within the existing ROW. 5.1.7 King County The project ROW crosses King County in lands dominated by suburban, light industrial, and urban land uses. The ROW follows the Military Road ROW along the eastern shoulder, which is generally composed of gravel road fill. In the City of Seattle, the ROW enters existing utilities ducts for the final portion of the ROW into downtown Seattle. The area includes portions of the White and Green/Duwamish river watersheds. The terrain has little relief, consisting of glacial sediments, but some steep sideslopes occur in the ROW. Elevations vary from approximately 400 feet on the highest glacial landforms to near sea level near the Duwamish River. Upland vegetation communities within the ROW are dominated by Himalayan blackberry, salmonberry, and young red alder and Douglas-fir. Wetland vegetation communities within the ROW are represented by reed canarygrass, seedlings and saplings of red alder, Douglas spirea, salmonberry, and evergreen blackberry. Most plant communities adjoining the ROW consist of cultivated plants or weedy areas dominated by Himalayan and evergreen blackberries, Scots broom, and red alder. Williams Communications, Inc.

Setting A!arch 2000 r'N,tTgti!gi 5.2 ACTION AREA The action area is the area of potential impact to addressed species. This area varies for different species. For bald eagles, spotted owls and marbled murrelets, it is delineated as described in Sections 6.17.1, 6.18.1 and 6.19.1, respectively. For salmonids, the action area extends from the project ROW to the farthest point downstream where fine sediment from the project might affect fish habitat. This is assumed to be the mouth of each Water Resource Inventory Area (WRIA) that the project passes through. The principal river in each of these WRIAs has a very low gradient or enters a lake or the ocean in its lower reaches, thus it is unlikely in practice that sediment could be delivered that far downstream. In practice, virtually all potential impacts to aquatic resources, if not mitigated by conservation measures, would occur within the first mile downstream from the project ROW. 5.3 WATERSHEDS 5.3.1 Willamette River Watershed: City of Portland The Willamette River watershed drains 12,000 square miles of Oregon between the Cascade Range and the Coast Range. Precipitation ranges from 40 to 200 inches with most, falling between October and May. Peak streamflow typically occurs between November and March in response to persistent winter rain and spring snowmelt; however, spring snowmelt can prolong high flows into June or July. Land use is approximately 70% forest, 22% agricultural, and 8% urbanized or other. The project ROW will cross the Willamette River twice, and crosses Columbia Slough, via directional drilling, and will cross several tributary streams. Within the project ROW, the Willamette River is listed on the 303(d) list (impaired and threatened surface waters) for temperature, mercury, creosote, and bacteria (Washington Department of Ecology 1999). Federally listed, proposed, or candidate fish species occurring in the Willamette River watershed consist of the Upper Willamette River chinook salmon ESU (Evolutionarily Significant Unit), the Upper Willamette River steelhead salmon ESU, the Columbia River bull trout DPS, and the Lower Columbia River /Southwestern Washington sea -run cutthroat trout ESU. 5.3.2 The Lower Columbia River Watershed: City of Portland, Clark County The Columbia River drains an area of 259,000 square miles and flows 1,243 miles from its headwaters in the Canadian Rockies, across the state of Washington, and along the Washington- Oregon border to its mouth at the Pacific Ocean. The fiber optic line will involve drilling the Columbia River above the mouth of the Willamette River, and this will occur in the lower Columbia River watershed. The Lower Columbia River watershed includes the Columbia River and its tributaries downstream from the Bonneville Dam, an area of about 18,000 square miles. Precipitation in the Lower Columbia River watershed ranges from 37 inches to 113 inches, with most falling between November and March. Spring snowmelt, winter rain, and dam regulation all affect streamflows. Land use is 74% forest, 17% agricultural, and 5% urban. Within the Lower Columbia River watershed, the project will cross 17 Type 1; 6 Type 2; 49 Type 3; 4 Type 4; and 25 Type 5 waters (see Appendix B for watershed type classifications and Williams Communications, Inc.

All of these stream crossings lie within the ROW for existing road and pipeline crossings. Fish habitat within the watershed varies greatly in quality, from pristine /optimum to severely degraded. Within the project ROW, most habitat indicators reflect significant adverse human impacts, as detailed in Chapter 6 for each of the fish species addressed. Federally listed, proposed, or candidate fish species occurring in the Lower Columbia River watershed consist of one distinct population segment (DPS) of Columbia River bull trout, and 13 evolutionarily significant units (ESU) of salmonids: Lower Columbia River chinook salmon; Upper Columbia River chinook salmon; Snake River chinook salmon; Upper Willamette River chinook salmon; Lower Columbia River steelhead; Middle Columbia River steelhead ESU; Upper Columbia River steelhead; Snake River steelhead; Upper Willamette River steelhead salmon; Snake River sockeye; Columbia River chum salmon; Lower Columbia River /Southwestern Washington sea - run cutthroat trout; and, Lower Columbia River /Southwest Washington coho salmon. The project ROW within the Lower Columbia River watershed passes through portions of three major subbasins: Oregon's Willamette River watershed (described above), the Lewis River (Washington Water Resources Inventory Area [WRIA] 27), and Cowlitz River (Washington WRIA 26) watersheds. 5.3.3 Lewis River Watershed, WRIA 27: Clark and Cowlitz Counties The Lewis River drains an area of 1,077 square miles. The Lewis River WRIA contains streams that are 303(d) listed for fecal coliform, dissolved oxygen, arsenic, DDE, PCBs, temperature, and pH (Ecology 1999). Within the project ROW, the Kalama River is listed for pH and temperature; the East Fork Lewis River is listed for temperature; and, McCormick Creek is listed for fecal coliform and temperature. Federally listed, proposed, or candidate fish species occurring in the Lewis River watershed consist of the Lower Columbia River chinook salmon ESU, the Lower Columbia River steelhead ESU, the Columbia River bull trout DPS, and the Lower Columbia River /Southwestern Washington sea -run cutthroat trout ESU. 5.3.4 Cowlitz River Watershed, WRIA 26: Cowlitz and Lewis Counties The Cowlitz River drains an area of 2,496 square miles. The Cowlitz River WRIA contains streams that are 303(d) listed for fecal coliform, dissolved oxygen, arsenic, temperature, and pH (Ecology 1999). Within the project ROW, the Coweeman River is listed for pH, dissolved oxygen, and temperature; the Cowlitz River is listed for arsenic, pH, temperature, and fecal coliform; and, the Toutle River is listed for fecal coliform and temperature. Federally listed, proposed, or candidate fish species occurring in the Cowlitz River watershed consist of the Lower Columbia River chinook salmon ESU, the Lower Columbia River steelhead ESU, the Columbia River bull trout DPS, and the Lower Columbia River /Southwestem Washington sea - run cutthroat trout ESU.

The Chehalis watershed is divided into two WRIAs, the Upper Chehalis (WRIA 23) and the Lower Chehalis (WRIA 22). The project ROW lies within the Upper Chehalis (WRIA 23) only. Precipitation averages from 40 to 220 inches in various parts of the watershed, with most falling as rain from October through March (LCCD 1992). Peak streamflows occur from December to March, and low flows from July through September (Pickett 1992). In 1991, timberland comprised 77% of the upper watershed and 91% of the lower watershed, agricultural land comprised 10% of the watershed, and urban uses comprised 3% of the watershed (LCCD 1992). In 1992, there were 28 salmon and steelhead stocks within the watershed with 75% classed as healthy, 11% as depressed, 14% as unknown, and none were critical (SASSI 1993). Various streams in the Upper Chehalis watershed are 303(d) listed for fecal coliform, dissolved oxygen, PCBs, temperature, and pH. Within the project ROW, Berwick Creek is listed for fecal coliform; Dillenbaugh Creek is listed for fecal coliform, temperature, and dissolved oxygen; the Newaukum River is listed for fecal coliform and temperature; Salzer Creek is listed for temperature and fecal coliform; and the Skookumchuck River is listed for pH, temperature, and fecal coliform. Fish habitat loss and degradation have occurred throughout much of the watershed due to channel modifications, loss of riparian functions, water quality impairment, increased sediment inputs, loss of in -stream woody debris, and improper culvert installation (SSHIAP 1997). Within the Upper Chehalis River watershed, the project ROW includes 2 Type 1; 0 Type 2; 19 Type 3; 7 Type 4; and 6 Type 5 waters (Appendix C). All the stream crossings lie within existing pipeline ROWs. Streams within project ROW typically have impaired fish habitat due to impaired riparian functions and absence of in- stream structure. Federally listed, proposed, or candidate fish species occurring in the Cowlitz River watershed consist of the Lower Columbia River /Southwestern Washington sea -run cutthroat trout ESU and the Coastal/Puget Sound bull trout DPS. 5.3.6 Puget Sound Watershed, WRIAs 13, 10, 11, and 9: Thurston/Pierce /King Counties The Puget Sound Watershed drains 13,600 square miles, encompassing Puget Sound and its adjacent waters, including lands that drain to the Strait of Georgia below the Canadian border and to the eastern part of the Strait of Juan de Fuca. The Puget Sound Watershed is bounded on the east by the Cascade Range and on the west by the Olympic Mountains. The climate is characterized by cool wet winters and warm dry summers. Precipitation varies from about 16 to 53 inches per year in the lowlands, and from 60 to 200 inches per year in the mountains. Twelve major and numerous minor tributaries drain to Puget Sound and adjoining waters. Within the project area, there are two routes under consideration within Pierce County: the Williams Pipeline Fort Lewis and the Fort Lewis reroute. Within the Williams Pipeline Fort Lewis project area, there are 8 Type 1; 2 Type 2; 17 Type 3; 3 Type 4; and 8 Type 5 waters. Within the Fort Lewis reroute project area, there are 7 Type 1; 0 Type 2; 22 Type 3; 2 Type 4; Williams Communications, Inc.

All stream crossings lie within existing road and pipeline ROWs. Fish habitat within the watershed varies greatly in quality, from pristine /optimum to severely degraded. Streams within the project ROW typically have impaired fish habitat due to impaired riparian function and absence of in -stream structure. The project ROW passes through four WRIAs within the Puget Sound watershed: the Deschutes River Watershed (WRIA 13), the Nisqually River Watershed (WRIA 11), the Puyallup River Watershed (WRIA 10), and the Green/Duwamish River Watershed (WRIA 9). Federally listed, proposed, or candidate fish species occurring in the Puget Sound watershed consist of the Puget Sound chinook salmon ESU, the Coastal/Puget Sound bull trout DPS, and the Puget Sound/Strait of Georgia coho salmon ESU. 5.3.7 Deschutes River Watershed, WRIA 13: Thurston County The Deschutes River drains an area of 179 square miles. Various streams within the Deschutes WRIA are 303(d) listed for fecal coliform, instream flow, fine sediments, large woody debris, mercury, temperature, and pH (Ecology 1999). Within the project ROW, the Deschutes River is listed for fecal coliform, instream flow, and temperature. Urbanization in the lower reaches of the WRIA is contributing to deterioration of water quality and salmonid habitat in some reaches. Within the Deschutes River watershed, the project ROW includes 1 Type 1; 0 Type 2; 1 Type 3; 0 Type 4; and 0 Type 5 waters (Appendix C). Presently, salmonid stocks are generally considered healthy. Habitat degradation or reduced base flow could contribute to declines in fish stocks in the future. 5.3.8 Nisqually River Watershed, WRIA 11: Thurston/Pierce Counties The Nisqually River watershed drains an area of 720 square miles with the mainstem flowing approximately 80 miles from the glaciers of Mount Rainier to Puget Sound below the Town of Nisqually. The Nisqually River from its mouth to Alder Dam (RM 44.2) is currently designated by the Department of Ecology as Class A (excellent) freshwaters of the state as per WAC 173-201A. The Lower Nisqually River is influenced by tides, thus qualifying it as a Marine Class A Water due to salinity. However, various streams within the Nisqually WRIA are 303(d) listed for fecal coliform, dissolved oxygen, chromium, temperature, and pH. Within the project ROW, there are no current listed waterways for 303(d). In 1992, the Nisqually River had healthy runs of fall chinook, chum, pink, and coho salmon, as well as winter steelhead (SASSI 1993). Sockeye salmon are occasionally seen, but the run size is insignificant compared to the other anadromous species. The majority of the Nisqually River provides good quality spawning and rearing habitat for anadromous and resident salmonids (Williams et al. 1975). 5.3.9 Puyallup River Watershed, WRIA 10: Pierce County The Puyallup White WRIA covers 972 square miles and includes the Puyallup, Carbon, and White river watersheds. The headwaters of these river systems are on Mount Rainier and all three rivers discharge through the Puyallup River into Commencement Bay and Puget Sound at Williams Communications, Inc.

Various streams within the Puyallup WRIA are 303(d) listed for fecal coliform, lead, dissolved oxygen, arsenic, temperature, and pH. Within the project ROW, the Puyallup River is listed for arsenic and fecal coliform; Wapato Creek is listed for dissolved oxygen, instream flow, and fecal coliform; Meeker ditch is listed for fecal coliform, temperature, dissolved oxygen, and pH; and, an unnamed creek is listed for fecal coliform. w• ' JU O 0 U) 0 cn w; LLI w o; LLQ =• d i Z F- 1— 0 Z U-1 ILI U � • E• -` ww 1— V: wz U —' 0 z. The salmonid habitats of the White River and the Lower Puyallup drainage have been severely affected by human activities. The U.S Fish and Wildlife Service determined that fish passage to the spawning grounds is the most critical problem confronting anadromous fish in the Puyallup River Watershed. 5.3.10 Green — Duwamish River Watershed, WRIA 9: King County The Green — Duwamish River watershed drains an area of 483 square miles with the mainstem flowing from the Cascade Range south of Stampede Pass 90.5 miles northwest to Elliott Bay. Various streams within the Green — Duwamish WRIA are 303(d) listed for fecal coliform, dissolved oxygen, PCBs, heavy metals and chemicals, temperature, and pH (Ecology 1999). Within the project ROW, the Green — Duwamish River is listed for various heavy metals and chemicals, temperature, fecal coliform, PCBs, and pH. Eight species of salmonids occur within the basin: summer- and fall -run chinook, coho, chum, rainbow /steelhead, both resident and sea -run cutthroat, and Dolly Varden. Little is known of their current status, but they have declined dramatically in response to habitat loss or degradation, and overfishing. Williams Communications, Inc.

Setting March 2000 :'h Section 6 Evaluation of Listed Species 6.1 DEFINITION OF TERMS The Endangered Species Act requires that federal agencies consider several types of effects that a fiber optic line may have on a listed species or its designated critical habitat: Direct effects result from actions that will immediately take individuals or adversely modify designated critical habitat. Indirect effects are caused by the fiber optic line and are delayed, but are still reasonably certain to occur. Interdependent and /or interrelated effects are effects from actions that (1) have no independent utility apart from the primary action, or (2) are part of a larger action and depend on the larger action for their justification, and/or (3) are required as part of the action, including maintenance and/or use of the project, as well as other actions that will be carried out to implement, maintain, and/or operate the project. Cumulative effects are those effects of future state or private activities, not involving federal activities that are reasonably certain to occur within the project ROW. The environmental baseline (50 CFR Part 402.02) consists of: • the past and present effects of all federal, state, or private actions and other human activities in the action area; • the anticipated impact of all proposed federal projects in the action area that have already undergone formal or preliminary Section 7 consultation; and, • the impact of state or private actions that are contemporaneous with the consultation. Conservation (or mitigation) measures are measures proposed to minimize or compensate for project effects on a species. Effects determinations, as defined below, are based on the assumption that conservation measures will be incorporated into the project. Effects determinations are the formal findings of the biological assessment (BA). The BA must contain one of four determinations of the net effect of the project on each species and/or designated critical habitat type. Possible effects determinations for listed species and designated critical habitat are (1) "no effect;" (2) "may affect, not likely to adversely affect;" (3) "may affect, likely to adversely affect;" or (4) "beneficial effect." For proposed critical habitat, possible effects determinations are (1) "will" or (2) "will not" result in "destruction or adverse modification of proposed critical habitat." For proposed species or proposed critical Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle. Washington Biological Assessment 6-1 Section 6. Evaluation of Listed Species Alarch 2000 habitat, possible effects are (1) "no jeopardy" or (2) "jeopardy." For candidate species, possible effects determinations are (1) "no impact" or (2) "may impact." 6.2 CHINOOK SALMON: THE LOWER COLUMBIA RIVER ESU 6.2.1 Action Area The action area extends from the project ROW to the farthest point downstream where fine sediment from the project might affect fish habitat. This is assumed to be the mouth of each WRIA that the project passes through. The principal river in each of these WRIAs has a very low gradient or enters a lake or the ocean in its lower reaches, thus it is unlikely that sediment will, in practice, be delivered this far downstream. In practice, virtually all potential impacts to aquatic resources, if not mitigated by conservation measures, will occur within the first mile downstream from the project ROW. 6.2.2 Chinook Stocks within Project Vicinity The Lower Columbia River ESU was designated threatened on March 24, 1999 (64 FR 14308). This ESU includes all naturally spawned chinook populations from the mouth of the Columbia River to the crest of the Cascade Range, excluding populations above Willamette Falls (Myers et al. 1998). Long -term population trends for the ESU are mixed with larger stocks being positive; short-term trends, negative. There has been an overall reduction in naturally spawning fish with a complete or nearly complete replacement of native spring -run stocks with stocks from outside ESUs. Juvenile and adult chinook of the Lower Columbia River ESU may migrate through, spawn, and rear in the project ROW. The adult spring -run migration occurs from April to June; the fall run, from August to October. The juvenile out - migrant peak occurs in May for the spring run, and from June to July for the fall run. Stocks in Washington tributaries below Bonneville Dam are considered healthy except for the South Fork Toutle River stock, which is considered depressed. Stocks in the Oregon tributaries below Bonneville Dam are also considered depressed. 6.2.3 Habitat Requirements and Ecology Chinook salmon display two life history patterns, referred to as "ocean type" and "stream type" (Groot and Margolis 1991). "Ocean type" juveniles usually migrate to sea within 3 months after emerging from the spawning gravel, although they may rear in freshwater for up to one year (63 FR 11481, March 9, 1998). "Stream type" fish reside as fry or parr in freshwater for one year or more before migrating to the sea. "Ocean type" chinook commonly inhabit coastal tributaries from Vancouver Island, south, while "stream type" chinook inhabit colder latitudes from Vancouver Island, north, and higher elevations (e.g., some Upper Columbia River tributaries), although these boundaries are not exclusive. In most stocks, one or the other life history pattern predominates. Chinook salmon are typically characterized as "spring - ", "summer - ", or "fall -run" according to the time adults enter fresh water to begin the spawning migration. In general, spring -run salmon are "stream type" fish whereas fall- and winter -run Williams iams Communications, Inc. Fiber Optic Line Svstem Installation Project Portland, Oregon to Seattle, Washington Biological Assessment Section 6. Evaluation of Listed Species March 2000 chinook salmon are "ocean" type fish. Populations identified as summer -run chinook salmon have "ocean" type life history patterns in some areas and "stream" type life histories in others. Chinook salmon require clean cool water and clean gravel to spawn. Females deposit their eggs in the gravel bottom in areas of relatively swift water. The eggs hatch 6 to 12 weeks later. Fry remain in the gravel another 2 to 4 weeks until the yolk is absorbed (Beauchamp et al. 1983; Allen and Hassler 1986). For maximum survival of eggs and fry, water temperature must range between 41°F and 57 °F with little variability. Optimum rearing habitat consists of pools and wetland areas with woody debris and overhanging vegetation. Estuaries also provide important rearing habitat where young fish may reside for weeks. Chinook salmon typically spend two to four years maturing in the ocean before returning to their natal streams to spawn. All adults die after spawning (Beauchamp et al. 1983; Allen and Hassler 1986). 6.2.4 Designated Critical Habitat Critical habitat designated on February 16, 2000 (65 FR 7778) includes all river reaches accessible to chinook salmon in the Columbia River and its tributaries between the Grays and White Salmon rivers in Washington, and the Willamette and Hood rivers in Oregon, inclusive. Also included are river reaches and estuarine areas in the Columbia River from the Clatsop jetty and the Peacock jetty upstream to the Dalles Dam. 6.2.5 Analysis of Effects Within the action area, forest management, agricultural practices, dams, and urbanization have greatly reduced suitable habitat for chinook salmon during all life stages, leaving little spawning and rearing habitat. The remaining salmonid habitat in the action area is fragmented, sparse, and in poor condition. The following evaluates potential effects of the project on water quality. Conservation measures described in Section 3.5, and summarized below, are designed to avoid or minimize the potential for water quality impacts. 6.2.5.1 Direct Effects Potential impacts during project execution (direct effects) include: • In -water activities in fish- bearing waters (Type 1, 2, and 3 waters) could cause stress, physical injury, or death to salmonids (including all life history stages) present in the project ROW. This impact will be avoided by avoiding all in -water work in potentially fish- bearing waters and waters that have fish immediately downstream (Type 4 streams). • Conduit and fiber optic line installation and associated soil disturbance could cause erosion of road embankments, channel beds, or banks. Construction equipment can compact soils, leading to accelerated runoff and localized sheet erosion and gullying. Disturbing ditch lines, which function as extensions of the stream network, also could result in sediment delivery to stream channels in the action area. Fine sediment can Williams Communications, Inc. Fiber Optic Line Svstem Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6 -3 Section 6. Evaluation of Listed Species March 2000 J adversely affect salmonids by creating turbidity and reducing water circulation through redds. Fine sediment can adversely affect salmonid habitat by embedding gravels and filling pools. Coarse sediment can adversely affect salmonid habitat by filling pools and by altering channel morphology. These impacts will be minimized by implementing the best management practices (BMPs) as per the Stormwater Pollution Prevention Plan (SWPPP); see also Section 3.5.2 Best Management Practices. Erosion controls will minimize sediment delivery to streams (e.g., silt fencing, buffers). • Use of guided drilling equipment could result in an accidental spill of drilling fluids into, or adjacent to, stream channels. The drilling fluid consists largely of a bentonite slurry. Bentonite is a swelling clay. Any bentonite spills delivered to surface waters will have the same effects as other forms of fine sediment delivered to surface waters. These impacts will be minimized by drilling at an adequate depth below surface waters and by conducting soils tests. Additionally, this and other potential direct effects will be avoided or minimized by having environmental monitors present onsite during construction to ensure that conservation measures are observed and any problems are promptly detected and addressed. • Hazardous materials associated with the fiber optic line include substances associated with construction equipment, such as gasoline and diesel fuels, engine oil, and hydraulic fluids. Any spillage of these substances could contaminate surface water and groundwater, stream channels, soils, wetlands, and other environmentally sensitive areas. Delivery of these contaminants to surface waters could cause stress or death to salmonids resident in the action area. Such impacts will be minimized by numerous measures described in the SWPPP (see also Section 3.6.2 Spill Prevention and Pollution Control). 6.2.5.2 Indirect Effects Indirect effects include effects that may occur during operation of the facility subsequent to project completion. Indirect effects include: • Improper compaction from proposed plowing in Type 5 waters (intermittent, non - fish- bearing streams), and dry Type 4 waters could increase rates of bed, bank, and channel erosion. Any resulting delivery of fine and coarse sediments to surface waters could have the same sediment - related impacts as described Section 6.2.5.1. These effects will be minimized by installing erosion control devices and revegetating construction sites. These measures will be monitored as prescribed by environmental permits, including Hydraulic Project Approval (HPA) and wetlands permits. • All other direct effects described above, except for bentonite spills, could also occur during facilities maintenance following project completion, and will be avoided or minimized by following similar conservation measures (erosion control, SWPP, permit requirements, etc.).

There will be no adverse cumulative effects from this project because conservation measures will be in place to avoid all sensitive resources. 6.2.6 Compliance with Recovery or Management Plans No recovery plan has been developed for this ESU. 6.2.7 Conservation Measures Conservation measures associated with the fiber optic line are detailed in Section 3.5. 6.2.8 Determination of Effect The project has been evaluated for chinook salmon using the NMFS determination of effects matrix (NMFS 1996). Indicators for project effects are presented in Table 7. Special- status salmonid species could occur in most fish- bearing streams crossed by the ROW, and are known to occur in many of these streams. The fiber optic line is designed to avoid effects on aquatic species by means of the conservation measures described above. Based on the following discussion, the fiber optic line may affect, but is unlikely to adversely affect, Lower Columbia River chinook salmon. Williams Communications, Inc.

Fiber Optic Line System installation Project Portland/ Oregon to Seattle, Washington Biological Assessment 6_6 Section 6. Evaluation of Listed Species March 2000 6.2.8.1 Water Quality 6.2.8.1.1 Temperature Alteration or removal of riparian vegetation that provides shade to streams reduces the canopy coverage and may therefore lead to increases in both average stream temperature and temperature variability. The degree of shading provided depends in part upon the vegetation cover surrounding the stream, with tall trees providing greater shade. Because of previous disturbance, much of the riparian vegetation along the proposed ROW consists of low shrubs, which provide relatively little shade to streams. To maintain the existing temperature regime in streams, the following buffer zones for riparian vegetation will be established during project activities. • No mature conifers will be removed within 300 feet of any stream channel; • Type 1, 2 and 3 waters, and Type 4 waters (if flowing at time of construction), will be crossed by directional drilling from outside city and county regulated buffers. If conditions strictly prohibit drilling a particular stream (e.g., geological or topographic conditions), the WDFW habitat biologist will be notified prior to initiation of alternative construction methods (i.e. plowing or trenching). If instream construction is permitted, in -water activities will occur only during agency- approved in- water' work windows.. • At a minimum, construction buffer widths prescribed by each local jurisdiction for fish- bearing streams (Type 1, 2, and 3, and Type 4 streams if flowing at time of construction) will be maintained to protect fish- bearing surface waters (refer to Appendix E for jurisdictional buffer requirements). • Type 5 and dry Type 4 waters will be plowed, but any bed and/or bank disturbance that occurs will be restored to pre - construction condition upon project completion. The ROW lies within an existing pipeline corridor and/or along existing roads. Most of the existing riparian vegetation, consisting of low shrubs with few trees, is in poor condition. The project activity will not alter pre - project conditions and will thus "maintain" current temperature conditions. 6.2.8.1.2 Sediment/Turbidity Increased sediment influx can result from upland, bank, and/or instream disturbance and loss of vegetation along the channel's edge. Project construction and operation will not alter pre - project conditions. The city and county riparian buffer width requirements will prevent bank disturbance and sediment delivery to the stream resulting from any upland disturbance. Type 1, 2, 3, and flowing Type 4 waters will be drilled, while Type 5 waters and dry Type 4 waters will be plowed. Any bed and bank disturbance will be restored upon completion of construction. Thus, project construction will "maintain" sediment/turbidity conditions. There is a possibility that, while drilling, ground fracture could allow bentonite to seep to the surface, temporarily causing increased turbidity. Monitoring of all drill sites could help minimize any possible bentonite spills. If a bentonite spill occurs, the equipment will be immediately shut down and the Williams Communications, Inc. Fiber Optic Line System Installation Project Portland Oregon to Seattle. Washington Biological Assessment 6 -7 Section 6. Evaluation of Listed Species March 2000 spill will be cleaned up promptly, in accordance with SWPPP provisions. However, over the long term, water quality will be "maintained." 6.2.8.1.3 Chemical Contamination/Nutrients Williams will prepare and implement a SWPPP that will define spill prevention measures such as storing hazardous substances and servicing equipment at the minimum jurisdictional riparian buffer width requirement from streams and other surface waters. Thus, the potential for adverse effects to threatened and endangered species will be minimized. The fiber optic line will not alter pre - project conditions and will thus "maintain" chemical contamination/nutrients. 6.2.8.2 Habitat Access 6.2.8.2.1 Physical Barriers Since no work will be conducted within Type 1, 2, 3, or flowing Type 4 waters, project construction and operation will not alter pre - project conditions and physical barriers will be "maintained." Installation of the fiber optic line will occur under (i.e. drilled) the stream beds in Type 1, 2, 3, and flowing Type 4 waters to avoid in -water work. Within dry Type 4 waters and Type 5 waters, fording and plowing could occur, but bed and bank will be restored to pre- existing conditions upon project completion. 6.2.8.3 Habitat Elements 6.2.8.3.1 Substrate Embeddedness Since there is no in -water work within Type 1, 2, 3, or flowing Type 4 waters, substrate embeddedness will be "maintained," as project construction and operation will not alter pre - project conditions. Within Type 4 and 5 waters, the chance of embeddedness will be minimized because of project construction BMPs. Excess sediment should not be delivered in -stream due to the implementation of minimum jurisdictional riparian buffer width requirements from the channel's edge. 6.2.8.3.2 Large Woody Debris Since there is no in -water work in fish- bearing streams associated with this project construction and operation, the fiber optic line will not alter current conditions. Thus, in -stream large woody debris will be "maintained." The potential for future large wood recruitment will be "maintained" because no trees will be removed within the riparian buffers. Additionally, mature conifers within 300 feet of the channel's edge will not be removed. 6.2.8.3.3 Pool Frequency Sediment/turbidity can be delivered to the stream channel from upland, bank, and/or in- stream disturbance and loss of vegetation along the channel's edge. Since there is no in -water work in fish- bearing streams associated with this project construction and operation, the fiber Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington VT Biological Assessment 6 -8 Section 6. Evaluation of Listed Species Alarch 2000 n:,Tr.::^5;.;??i^v'•.,'�, optic line will not alter current conditions. Project construction and operation will maintain pool frequency because project construction and operation will not alter pre - project conditions. The minimum jurisdictional riparian buffer width requirements will prevent any bank disturbance and will provide a buffer from any upland disturbance that may occur. 6.2.8.3.4 Pool Quality Sedimentation in streams due to upland and bank disturbances can degrade pool quality. The minimum jurisdictional riparian buffer width requirements associated with project construction and operation will prevent bank disturbance and minimize the disturbance of potential upland sediment sources. Therefore pool quality will be "maintained" because project construction and operation will not alter pre - project conditions. 6.2.8.3.5 Off - channel Habitat Since there is no in -water work in fish- bearing streams associated with project construction and operation, off - channel habitat will be "maintained" because project construction and operation will not alter pre - project conditions. All sensitive resource areas (e.g. riparian habitat, stream bed and bank, associated wetlands) will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing off - channel habitat. 6.2.8.3.6 Refugia Since there is no in -water work in fish- bearing streams associated with project construction and operation, refugia will be "maintained" because project construction and operation will not alter pre - project conditions. Sensitive resource areas will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing refugia. 6.2.8.4 Channel Conditions and Dynamics 6.2.8.4.1 Width/Depth Ratio Since there is no in -water work in fish - bearing streams associated with project construction and operation, channel width/depth ratios will be "maintained" because project construction and operation will not alter pre - project conditions. Sensitive resource areas will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing width/depth ratio. 6.2.8.4.2 Streambank Condition Since there is no in -water work in fish- bearing streams associated with project construction and operation, streambank condition will be "maintained" because project construction and operation will not alter pre - project conditions. Sensitive resource areas will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing streambank condition.

Sensitive resource areas will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing peak/Base flows. 6.2.8.5.2 Increase in Drainage Network Since there is no in -water work in fish- bearing streams associated with project ►' construction and operation, the drainage network will be "maintained" because project construction and operation will not alter pre - project conditions. Sensitive resource areas will be avoided by either drilling under the area or attaching the line to an existing bridge, thereby maintaining the existing drainage network. 6.2.8.6 Watershed Conditions 6.2.8.6.1 Road Density and Location Project construction and operation will "maintain" road density and location because project construction and operation will not alter pre - project conditions. The project ROW lies within an existing pipeline corridor and/or along existing roads, and therefore no new roads will need to be built. 6.2.8.6.2 Disturbance History Project construction and operation will "maintain" disturbance history because project construction and operation will not alter pre - project conditions. The project ROW lies within an existing pipeline corridor and/or along existing roads, and therefore disturbance will be minimal. 6.2.8.6.3 Riparian Reserves Project construction and operation will "maintain" riparian reserves because project construction and operation will not alter pre - project conditions. Implementation of local jurisdictional riparian buffer width requirements will maintain the existing riparian areas. Williams Communications. Inc.

This ESU includes "stream type" chinook salmon spawning above Rock Island Dam, specifically those in the Wenatchee, Entiat, and Methow Rivers (Myers et al. 1998). Long -term and short-term population trends for the ESU are negative due to the loss of a significant portion of historic spawning and rearing habitats, and degradation of rearing habitat and migrational corridors. Juvenile and adult chinook of the Upper Columbia River ESU may migrate through the project ROW at the Columbia River. The adult spring -run migration occurs from March to June, and peaks in April. The juvenile outmigration peak occurs in May. The spring -run is considered depressed (WDF /WDW 1993). 6.3.3 Habitat Requirements and Ecology Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.3). 6.3.4 Designated Critical Habitat Critical habitat was designated on February 16, 2000 (65 FR 7778) and includes all river reaches accessible to chinook salmon in the Columbia River tributaries upstream of the Rock Island Dam, and downstream of the Chief Joseph Dam, excluding the Okanogan River. Also included are river reaches and estuarine areas in the Columbia River from the Clatsop jetty and the Peacock jetty upstream to the Chief Joseph Dam, Washington. 6.3.5 Analysis of Effects Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.5). 6.3.6 Compliance with Recovery or Management Plans No recovery plan has been developed for this ESU. 6.3.7 Conservation Measures Conservation measures associated with the fiber optic line are detailed in Section 3.5.

This ESU includes naturally spawned spring -run populations above Willamette Falls (Myers et al. 1998). Fall chinook salmon above Willamette Falls are not considered a population for defining this ESU (Myers et al. 1998). Long -term and short-term population trends for the ESU are negative. Juvenile and adult chinook of the Upper Willamette River ESU may migrate through the project ROW at Multnomah and the Columbia River. Timing of the adult spring -run migration occurs April to June and peaks in May. Juvenile outmigration peaks occur from July to August. The spring run is considered mixed (WDF/WDW 1993). 6.4.3 Habitat Requirements and Ecology Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.3). 6.4.4 Designated Critical Habitat Critical habitat was designated on February 16, 2000 (65 FR 7778) and includes all river reaches accessible to chinook salmon in the Clackamas River and the Willamette River and its tributaries above Willamette Falls.

This ESU occupies the Willamette River and its tributaries upstream from Willamette Falls. Of the three tributary winter steelhead stocks inventoried, two have been declining and one increasing over the available data series, with a range from 4.9% annual decline to 2.4% annual increase (Busby et al. 1996). Juvenile and adult steelhead of the Upper Willamette River ESU may migrate through the project ROW at Multnomah County and the Columbia River. The adult migration occurs from October to March and the juvenile outmigration peak occurs in May. The run is considered depressed (WDF/WDW 1993). 6.8.3 Habitat Requirements and Ecology Two groups exist within Oregon and Washington, inland and coastal, which are separated in the Columbia and Fraser River systems in the vicinity of the crest of the Cascade Mountains (Reisenbichler et al. 1992). Coastal populations in Washington typically mature at four years, spending two years in freshwater and two years in the ocean. Columbia River Watershed inland populations typically mature at four years, spending two years in freshwater, one year in the ocean, and one year in freshwater as an adult prior to spawning (Busby et al. 1996). Anadromous forms may spend up to seven years in freshwater and three years in the ocean, prior to first spawning with the ability to spawn more than once. Generally, summer steelhead enter freshwater from May to October in a sexually immature state, migrate upstream during the spring and summer, and hold in areas of protected cover such as debris or boulder structures until they become sexually mature. Then they hold over the fall and winter in freshwater. Inland steelhead from the Columbia River Watershed and the Snake River Watershed are split into two groups (A- and B -run) based upon a bimodal migration of adult steelhead differing in age at return and adult size (Busby et al. 1996). A -Run fish enter freshwater from June to August and usually spend 1 year in the ocean before returning to spawn. B -run fish enter freshwater from late August to October and usually spend two years in the ocean before returning to spawn (Busby et al. 1996). Winter steelhead enter their natal stream in various stages of sexual maturation from November to April, and spawn within a few months of entering the river between late March and early May (Pauley et al. 1986). After hatching and emergence, they move to deeper parts of the stream. Important rearing habitat includes streamside vegetation and submerged cover (e.g. logs, rocks, and aquatic vegetation).

This ESU occupies tributaries to the Columbia River between the Cowlitz and Wind rivers in Washington, and the Willamette and Hood rivers in Oregon, inclusive. Excluded are steelhead in the upper Willamette River Watershed above Willamette Falls, and steelhead from the Little and Big White Salmon rivers, Washington. The ESU is composed of winter and summer steelhead (Busby et al. 1996). The strongest positive trends are occurring either in non - native stocks (Lower Willamette River and Clackamas River) or in stocks that are recovering from major habitat disruption (e.g., 1980 eruption of Mount Saint Helens), and are still at low abundance (mainstem and North Fork Williams Communications, Inc.

Of the 18 stocks inventoried, 11 have been declining and seven increasing during the available data series, with a range from 24% annual decline to 48% annual increase (Busby et al. 1996). Juvenile and adult steelhead of the Lower Columbia River ESU may migrate through, spawn, and rear in the project ROW. The adult summer -run migration occurs May to November, and the winter run occurs from December to April for the Washington tributaries below Bonneville Dam. The adult winter -run migration on the Oregon tributaries below Bonneville Dam occurs from late February to mid -June. The Juvenile outmigration peaks in May for all runs.

This ESU occupies the Columbia River Watershed upstream from the Wind River in Washington and the Hood River in Oregon to include the Yakima River in Washington. This ESU includes the only populations of winter inland steelhead in the United States, in the Klickitat River and Fifteenmile Creek (Busby et al. 1996). Of the 14 independent stock indices available, 10 have been declining and 4 increasing during the available data series, with a range from 20% annual decline to 14% annual increase (Busby et al. 1996). Juvenile and adult steelhead of the Middle Columbia River ESU may migrate through the project ROW at the Columbia River. The adult summer -run migration occurs from July to , November, peaking in August to September, and the winter -run occurs from November to April, peaking in March.

This ESU occupies the Columbia River Watershed upstream from the Yakima River, Washington, to the United States —Canada border. Only naturally spawned populations of steelhead and their progeny that are part of the biological ESU residing long -term below both natural and man-made impassable barriers are listed. The Wells Hatchery stock of steelhead is included as listed in this ESU because it is essential for recovery (Busby et al. 1996). Trends in total (natural and hatchery) adult escapement are available for the Wenatchee River (2.6% annual increase, 1962 -1993) and the Methow and Okanogan rivers combined (12% annual decline, 1982 -1993) (Busby et al. 1996). These two stocks represent most of the escapement to natural spawning habitat within the range of the ESU, although the Entiat River also has a small spawning run (WDF/WDW 1993). Juvenile and adult steelhead of the Upper Columbia River ESU may migrate through the project ROW at the Columbia River. The adult summer -run migration occurs from July to November, peaking in August to September, and the winter -run occurs from November to April, peaking in March.

This ESU includes all natural populations of sockeye salmon in the Snake River Watershed, below Hells Canyon Dam and Dworshak Dam on the Clearwater River, including areas that were historically accessible to sockeye. Juvenile and adult sockeye of the Snake River ESU may migrate through the project ROW at the Columbia River. The adult Williams Communications, Inc.

Evaluation of Listed Species March 2000 summer -run migration occurs from mid -July to mid - September and juvenile outmigration peaks in May. The run is considered critical (WDF/WDW 1993). 6.13.3 Habitat Requirements and Ecology Of all salmon, sockeye exhibit the greatest variety of life history patterns, diversity in the selection of spawning habitat, and variation in the timing of river entry and the duration of holding in lakes prior to spawning. Adult sockeye typically enter freshwater from mid -June through August, and spawn 1 to 6 months later (Gustafson et al., 1997). Generally, the spawning beds are situated in areas with clean gravel, or along the borders between pools and riffles in shallow water with moderate to fast currents (Burgner 1991). In larger rivers, they may spawn in .. {,j discrete sections of main or tributary channels. Emergence commonly occurs from April to late May or early June, peaking in early to mid -May (Egorova 1970; Brannon 1972; Gustafson et al., 1997). Following emergence, "sea- type" sockeye migrate to the ocean or estuaries after several 111 months in freshwater.. "River- type" sockeye salmon rear for 1 to 2 years in rivers before migrating to the ocean (Birtwell et al. 1987, Eiler et al. 1992). Tidewater sloughs and estuaries provide rearing habitat before sockeye enter the marine environment, where 1 to 4 years are I ,4 spent before the fish returning to natal river system to spawn. 6.13.4 Designated Critical Habitat Critical habitat designated on December, 28 1993 (58 FR 68543) and includes all river reaches presently or historically accessible to listed sockeye in the Columbia River from the Pacific Ocean to its confluence with the Snake River and in the Snake River from its confluence with the Columbia River to its confluence with the Salmon River. 6.13.5 Analysis of Effects Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.5). 6.13.6 Compliance with Recovery or Management Plans No recovery plan has been developed for this ESU. 6.13.7 Conservation Measures Conservation measures associated with the fiber optic line are detailed in Section 3.5. 6.13.8 Determination of Effect The fiber optic line may affect but is not likely to adversely affect this species or adversely modify designated critical habitat.

This ESU extends to the mouth of the Columbia River. Juvenile and adult chum of the Columbia River ESU may migrate through, spawn, and rear in the project ROW. The adult migration occurs from November to January and juvenile outmigration peaks in April. The run is considered depressed (WDF/WDW 1993). 6.14.3 Habitat Requirements and Ecology Adults enter freshwater to spawn from October — January, peaking in mid November. Spawning peaks in late November and usually is completed by early December. In general, chum spawn in shallower, lower gradient, lower velocity streams and side channels. Fry typically emerge from the gravel at night and immediately migrate downstream to estuarine waters. Juveniles migrate downstream from late -January through May, utilizing estuaries to feed before starting oceanic migrations. Migration of chum salmon juveniles out of estuaries appears to be closely correlated with prey availability. Chum salmon juveniles move offshore as they reach a size that allows them to feed on the larger neritic plankton, and this movement normally occurs as inshore prey resources decline (Salo 1991). Chum typically reach maturity at three years. 6.14.4 Designated Critical Habitat Critical habitat for the ESU was proposed on March 10, 1998 (63 FR 11774) and includes all river reaches accessible to listed chum salmon (including estuarine areas and tributaries) in the Columbia River downstream from Bonneville Dam, excluding Oregon tributaries upstream of Milton Creek at river km 144 near the town of St. Helens. 6.14.5 Analysis of Effects Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.5). 6.14.6 Compliance with Recovery or Management Plans No recovery plan has been developed for this ESU.

The Columbia River DPS occurs throughout the entire Columbia River Watershed within the United States and its tributaries, excluding bull trout found in the Jarbidge River, Nevada. Juvenile and adult bull trout of the Columbia River DPS may migrate through, spawn, and rear in the project ROW. According to the WDFW, adult migration occurs from September to October. Although the stock is considered depressed (WDF/WDW 1993), the WDFW believes that populations in part of the DPS are slowly rebuilding (WDFW 1998). 6.15.3 Habitat Requirements and Ecology Bull trout exhibit resident and migratory life history strategies through much of their current range (Rieman and McIntyre 1993). Resident bull trout complete their life cycles in the tributary streams in which they spawn and rear. Migratory bull trout spawn in tributary streams from August to November. Juvenile fish rear from 1 to 4 years before migrating to either a lake, river, or saltwater. Habitat requirements include cool water temperature, cover, channel form and stability, valley form, spawning and rearing substrates, and migratory corridors. Spawning areas are often associated with cold -water springs, groundwater infiltration, and the coldest streams in a given watershed (Pratt 1992, Rieman and McIntyre 1993, Rieman et al. 1997).

The species is currently being considered for removal from the federal list of endangered and threatened wildlife (60 FR 36010). Early declines in bald eagle populations were attributed to human persecution and destruction of riparian, wetland, and coniferous forest habitats. The most important factor in the decline of the species, however, was the widespread use of organochloride pesticides that caused eggshell thinning and subsequent reproductive failure throughout the range of the species Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6-28 Section 6. Evaluation of Listed Species March 2000 (Detrich 1985). Currently, habitat loss and disturbance are the primary threat to bald eagles in the Pacific recovery area (USFWS 1986). In order to minimize potential disturbance to bald eagles, the U.S. Fish and Wildlife Service recommends a buffer of 800 meters (2,664 feet) around unscreened nests or roosts and 400 meters (1,312 feet) around screened nests or roosts during the nesting and winter periods, respectively (USFWS 1986). The draft management recommendations from the WDFW for bald eagle nests on non - federally owned lands recommend a buffer of 800 feet around a bald eagle nest site during the breeding season and 400 feet around roost stands during the winter (WDFW 1999). Because these guidelines are still in draft form, the more conservative guidelines from the Pacific States Bald Eagle Recovery Plan (USFWS 1988) will be implemented, as outlined above (Table 4, and section 3.5.5.1). 6.17.1 Action Area The action area includes the project ROW, as described in Section 3.1, and any area where disturbance may occur within 2,624 feet of a bald eagle nest, communal roost site, and/or regular foraging area. The 2,624 -oot analysis radius is based on the maximum buffer requirement for nest sites, as recommended by the USFWS for unscreened nests (USFWS 1978). Because nest sites are typically the most sensitive to disturbance, this buffer is also sufficient for analysis of roosting and foraging areas. 6.17.2 Bald Eagle Populations in the Project Vicinity Resident and wintering populations of bald eagles are present along portions of the ROW in both Washington and Oregon. Bald eagles are likely to use areas along the ROW throughout the year, including the breeding season (January 15— August 15) and wintering season (November 1 to March 31). 6.17.2.1 Areas of Known Use Known areas of eagle use in the vicinity of the proposed ROW are described in Tables 8 and 9. Use areas are separated into nest sites and winter roosting or foraging habitats. Williams Communications, Inc.

Where nests are located within 2,624 feet of the proposed right -of -way, Jones & Stokes has mapped management zones. Within these management zones, specific conservation measures have been developed, as per the Pacific States Bald Eagle Recovery Plan (U.S. Fish and Wildlife Service 1986), to minimize potential impacts to bald eagles (Section 3.5.5.). Of the known nest sites listed in Table 8, one has a nest site management plan in place. This nest is located in the Shillapoo Lake Wildlife Area (site 2N 1 W 12 in Table 8), on lands owned and managed by the state of Washington (WDFW 1996). The proposed ROW will be located adjacent to the bald eagle management zone in the Shillapoo Lake Wildlife Area, within the existing right -of -way of State Highway 501. This management zone contains both bald eagle nesting habitat and potential wintering habitat, and thus conservation measures for both seasons will be required for this portion of the ROW (see section 3.5.5). Application of these conservation measures will be consistent with the management plan for the Shillapoo Wildlife Area. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6 -31 Section 6. Evaluation of Listed Species March 2000 6.17.2.2 Potential Bald Eagle Use Areas Bald eagles occur as year -round residents in Washington and Oregon. Potential bald eagle foraging habitat, both summer and winter, has been identified within the vicinity of the proposed alignment, based on the PHS data (1999) and on field review of the proposed ROW. Important components of foraging habitat are availability of perch trees, availability of prey, and minimal human disturbance.

Bald eagles are opportunistic in their foraging behavior and often scavenge food items and steal from other predators (e.g., gulls, crows, and osprey) rather than hunting and killing prey (Stalmaster 1987). 6.17.3 Habitat Requirements and Ecology Bald eagles are associated with coastal environments, lakes, rivers, and marshes (Csuti et al., 1997). They feed mainly on fish but will also eat carrion, various water birds, and small mammals (Csuti et al., 1997). Although territory size varies, eagles will defend a few hundred yards around the nest (Csuti et al., 1997). Bald eagles typically nest in stands of old- growth trees near large water bodies (Johnsgard 1990). Nests are often constructed in the largest tree in a stand with an open view of the surrounding environment. Nest trees are usually near water and have large horizontal limbs. Snags and dead - topped live trees are important in providing perch and roost sites (Johnsgard 1990). 6.17.4 Designated Critical Habitat The USFWS has not designated critical habitat for bald eagles.

Evaluation of Listed Species March 2000 6.17.5 Analysis of Effects 6.17.5.1 Direct Effects Potential direct effects from this project include potential disturbance to nesting, foraging or roosting bald eagles, and potential alteration of bald eagle habitat. As described in Section 3.1, much of the proposed ROW follows existing roads, with most of the rest of the ROW following the existing Williams Pipeline Corporation natural gas pipeline right -of -way. Short sections of the ROW will be constructed in currently undeveloped areas, as will the OP -AMP stations. Construction activities associated with installing the line include trenching, laying conduit, and back - filling the trench. Building construction for the OP- AMP stations will also require the use of heavy equipment. River and stream crossings will be accomplished either by hanging the conduit from existing bridges or by drilling beneath the bed. Directional drilling is done using drilling equipment, and requires work areas to be established on either side of the area being drilled. Among the nesting and potential foraging sites located within 800 meters of the proposed alignment (Tables 8 and 10), 3 are located in areas where the proposed alignment follows within existing road rights -of -way (2N1W13, 2N1W12, and 22N4E33), and 15 are located in areas where the proposed alignment is within the existing Williams Pipeline right -of -way. No bald eagle nest trees will be removed in conjunction with this project. Noise disturbance to bald eagles from construction activities is possible. Disturbance to eagle nest sites will be minimized through the application of conservation measures BE1 and BE2 (see section 3.5.5). Compliance with conservation measures BE3 and BE4 will ensure that currently suitable habitat for bald eagles will not be altered or removed. Where winter roosts are identified, compliance with conservation measure BE2 will minimize potential disturbance to bald eagles. However, disturbance to bald eagles foraging or roosting in unmapped areas could occur, interrupting foraging or roosting activities. Since this potential disturbance cannot be predicted, it cannot be mitigated. This disturbance will be temporary in nature, and is not expected to affect eagle survival or productivity. 6.17.5.2 Indirect Effects Indirect effects are those that are reasonably certain to occur over a longer term and are associated with the action. Potential indirect effects to bald eagles associated with the fiber optic line include disturbance to nesting, foraging, or roosting sites as a result of ongoing maintenance or operations. Vegetation along the proposed ROW will be maintained in an early seral condition, as described in the Vegetation Management Plan for this project (Appendix D). Maintenance activities will include the use of chainsaws that have the potential to cause disturbance to nesting bald eagles. In areas where the proposed ROW follows an existing cleared right -of -way (along existing road alignments or the pipeline right -of -way), vegetation management is an established Williams Communications, Inc. Fiber Optic Line System Installation Project Portland Oregon to Seattle, Washington Biological Assessment 6 -34 Section 6. Evaluation of Listed Species March 1000 activity. In areas where the proposed alignment is not in an existing right -of -way, maintenance activities will be a new source of disturbance. Where maintenance activities will occur within 2,624 feet of a bald eagle nest, activities will be limited so that they comply with conservation measure BE1, minimizing potential disturbance to nesting bald eagles. Maintenance of vegetation in an early seral condition could prevent future development of potential roost or nest trees. Within known bald eagle nesting areas, clearing of trees not currently suitable for use as nest trees will be minimized to the extent possible in order to provide replacement habitat for currently suitable trees, which may be lost to naturally occurring events. Salmon are a primary food source for bald eagles, and potential project impacts to salmon could indirectly affect bald eagles by altering their food supply. Sections 6.2 through 6.16 discuss potential impacts to fish species in detail. Potential impacts to fish are expected to be f. minimal, however, because all salmon - bearing streams and rivers will be drilled. t' 6.17.5.3 Interdependent and /or Interrelated Effects 1 No new maintenance or access roads will be constructed in conjunction with this project. i.:, However, some existing roads will be upgraded and maintained for project construction, ' • maintenance, and operation. These roads have the potential to disturb nesting bald eagles if used repeatedly. Where possible, these roads will be located outside of the 2,624 -foot buffer around bald eagle nests. Where roads occur within this buffer, use will be limited to comply with conservation measure BE1. Access may be necessary during the nesting season, particularly for emergency repairs to the fiber optic line. Limiting non - emergency trips during the nesting season will reduce the potential disturbance to nesting bald eagles from these roads. 6.17.5.4 Cumulative Effects and Environmental Baseline Maintenance activities for existing roads or other rights -of -way areas are ongoing activities that could contribute to disturbance to nesting or foraging bald eagles within the vicinity of the proposed ROW. Limiting activities in known eagle use areas, as described in conservation measures BE1 and BE2, will minimize potential cumulative impacts from maintenance and operation of the fiber optic line. While several jurisdictions are implementing watershed - related projects and restoration activities in the project ROW, no specific non - federal actions are known that will cause significant effects, when considered collectively with this project. 6.17.6 Compliance with Recovery or Management Plans Implementation of conservation measures BE1 through BE 4 (Section 3.5.5.1) will ensure compliance with the Pacific States Bald Eagle Recovery Plan (USFWS 1986).

Evaluation of Listed Species March 1000 I It f;4 6.17.7 Conservation Measures Conservation measures are listed in section 3.5.5 of this document. 6.17.8 Determination of Effects No bald eagle nests will be removed, and no suitable nesting habitat will be removed or altered. Noise disturbance may occur as a result of project construction, maintenance, and operations; however, seasonal timing restrictions on these activities, as outlined in the conservation measures, will be implemented within the vicinity of known bald eagle nests and winter foraging sites. For these reasons, an affect determination of "may affect, not likely to adversely affect" has been reached for the bald eagle. 6.18 NORTHERN SPOTTED OWL The northern spotted owl was listed as a threatened species by the USFWS in 1990 (55 FR 26,194), and critical habitat for the northern spotted owl was designated in 1991 (57 FR 1796). Declines in spotted owl populations are thought to be a result of extensive habitat loss associated with timber harvesting ( Csuti et al., 1997; Gutierrez et al., 1995). Long -term viability of the remaining populations is uncertain (Csuti et al., 1997). 6.18.1 Action Area The action area includes the project ROW, as described in Section 3.1, and any area where disturbance may occur within 1.8 miles of a spotted owl nest site. The 1.8 -mile radius is the accepted management radius for nest sites within the project ROW, as recommended by the USFWS (1990). 6.18.2 Northern Spotted Owl Populations within the Project Vicinity The fiber optic line ROW passes through one spotted owl management circle (PHS data) and through one designated critical habitat unit (CHU), namely WA -53 (57 FR 1796). The spotted owl management circle is located near the Town of Toledo. This site was last surveyed in 1993 and the status of the circle was a pair, possibly with fledglings, although reproduction was not confirmed (A. Potter, pers. comm.). The current status is not known. The activity center for this circle is located approximately 2,800 feet east of the proposed ROW. Habitat conditions along the proposed ROW are not ideal for spotted owls, with much of the vegetation converted to agricultural fields, clearcuts, and developed homesites. Potential habitat may occur in parks within the vicinity of the owl circle (A. Potter, pers. comm.), including Lewis and Clark State Park, which is approximately 1 mile east - northeast of the activity center, and Matilda Jackson State Park, which is approximately 3 miles north - northeast of the activity center.

Evaluation of Listed Species March 2000 "k! f There are two ROW's under consideration through the Fort Lewis Military Reservation, and therefore through CHU WA -53. Both ROW's will pass through the same general vicinity and will have the same potential impact to spotted owls and their critical habitat; therefore, they are discussed together. CHU WA -53 is located on Fort Lewis, which is 52,000 acres in size. Of the 52,000 acres, approximately 4,160 acres (8 %) support stands that are greater than 100 years in age and considered suitable spotted owl habitat. These stands are highly fragmented, occurring throughout the base in small blocks. Many of these stands naturally develop into an open canopy type due to local growing conditions. Many of the oldest, most contiguous stands of coniferous forest on Fort Lewis are not located within the designated CHU. Spotted owl surveys conducted to existing protocol have failed to locate any spotted owls on Fort Lewis or within CHU WA -53 (Department of Defense 1993). 6.18.3 Habitat Requirements and Ecology The majority of known spotted owl nest sites are in old- growth or mature forest stands. In addition, the proportion of older seral stage forest surrounding nest sites is significantly greater than in random sites in the same area. In general, northern spotted owls nest in stands with greater complexity and structure than random sites in both managed and unmanaged fdrests. Nests typically occur in dense, multi - layered stands with high canopy closure but are occasionally found in sites lacking some of these characteristics. Spotted owls do not construct their own nests and are thus dependent upon naturally occurring nest sites such as broken -top trees, large tree cavities, or platform nests built by other animals (57 FR 1797). Roosting habitat typically consists of stands containing large- diameter trees with high canopy closure and multiple canopy layers. These sites tend to be in shady spots near streams on the lower third of the slope. Important components of foraging habitat include complex structure (e.g. multiple canopy layers, large downed woody debris, etc.) and high canopy closure (57 FR 1798). Spotted owl dispersal habitat is more variable, and at a minimum, must provide trees of adequate size and canopy closure to provide protection from predators and offer some foraging opportunity (57 FR 1798). 6.18.4 Designated Critical Habitat As mentioned previously, the proposed ROW will pass through one designated Critical Habitat Unit, CHU WA -53. This CHU currently contains scattered blocks of potentially suitable habitat. However, surveys using existing protocol have failed to locate spotted owls in this area (Department of Defense 1993). CHU WA -53 was designated as critical habitat with the knowledge that spotted owls did not occur in the area. This area is recognized as a potentially important island of habitat between spotted owl populations in the Cascades and the Olympics, and is being managed as spotted owl habitat so that it can function as a stepping -stone between populations. As a result, vegetation Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington radaw°nls ¢i" `n rr' Y z^ran cam: :.. Biological Assessment Ei -37 Section 6. Evaluation of Listed Species March 2000 • i management plans on Fort Lewis are designed to facilitate accelerated development and retention of suitable spotted owl habitat within currently forested areas (Department of Defense 1994). 6.18.5 Analysis of Effects 6.18.5.1 Direct Effects No suitable spotted owl habitat will be altered or removed as a result of the fiber optic line. In areas of potential owl occurrence, the proposed ROW will follow an existing right -of- way, either an existing pipeline or a road. Where the proposed ROW passes through the spotted owl management circle in Lewis County, small patches of potentially suitable habitat exist within 0.25 mile of the proposed alignment, although the activity center for this circle is approximately 0.5 mile from the alignment. Since the proposed ROW will follow the existing right -of -way for the natural gas pipeline in this area, no trees will be removed within the spotted owl management circle, as stated in conservation measure SOl (Section 3.5.5.2). Given that the proposed ROW in this area is located entirely on an existing maintained utility corridor and passes through lands with a high degree of both residential development and timber management, the construction activities are expected to be within the limits of existing disturbance. Since the activity center for this management circle is greater than 0.5 mile from the proposed ROW, no direct affects to spotted owls are expected in this area. Where the proposed ROW passes through CHU WA -53, there are small patches of habitat greater than 100 years old, with the majority of the vegetation being 85 years old or less. Large areas within the vicinity of the proposed ROW are within areas designated as Heavy Use Maneuver Corridors, which are areas utilized for armored vehicle training (Department of Defense 1993). Construction activities associated with the proposed ROW will occur within an existing maintained right -of -way, therefore no trees will be removed as per conservation measure S02. When considered in conjunction with surrounding land use, construction activities are expected to be within existing levels of disturbance. Since spotted owls are not currently known to occur within the CHU, no direct effects to spotted owls are expected in this area. Since suitable spotted owl habitat will not be removed or altered in conjunction with this project, no direct effect to critical habitat for spotted owls is expected to occur. 6.18.5.2 Indirect Effects Vegetation along the proposed ROW will be maintained in an early seral condition, as described in the Vegetation Management Plan for this project (Appendix D). Maintenance activities will include the use of chainsaws and other motorized equipment, which have the potential to cause disturbance to nesting spotted owls. Because the proposed ROW will follow existing rights -of -way through both the spotted owl management circle in Lewis County and through CHU WA -53, vegetation management is an existing activity and maintenance activities associated with the fiber optic line are expected to be within the existing levels of disturbance. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6-38 Section 6. Evaluation of Listed Species March 2000 `�R Operation activities, which could include repair of the line, will also be within existing levels of disturbance. When maintenance and operation activities are considered within the context of current land management activities and uses in the areas where the proposed ROW passes through potential spotted owl areas, the potential for disturbance from the fiber optic line is further reduced. t�l Maintenance of vegetation along the proposed ROW in an early seral condition will preclude-the development of that vegetation into suitable habitat for the northern spotted owl. Land use activities in the owl management circle in Lewis County in the vicinity of the proposed i '? ROW are not conducive to development of spotted owl habitat, with clearing and development predominating. If spotted owls are to persist in the area, they are most likely to do so in areas F.42 further to the east, which have been designated as forest land under the Lewis County l ' Comprehensive Plan (Lewis County, 2000), rather than in the proposed alignment which is mainly managed for agriculture or urban growth. t Maintenance of the proposed ROW in early seral condition through CHU WA -53 will also preclude development of suitable spotted owl habitat. However, the proposed ROW will occur within an existing right -of -way and the goal of the current vegetation management plan for Fort Lewis is to accelerate development of blocks of existing forested habitat into suitable spotted owl habitat, not increase the number of acres of forested habitat (Department of Defense 1993). Maintaining the right -of -way in an early seral condition will be consistent with this plan. 6.18.5.3 Interdependent and /or Interrelated Effects No new maintenance or access roads will be constructed in conjunction with this project, although some existing roads will be upgraded and maintained for construction, maintenance, and operation purposes. This activity is expected to be within the existing level of the disturbance in both the Lewis County owl management circle and CHU WA -53. 6.18.5.4 Cumulative Effects and Environmental Baseline Within the owl management circle in Lewis County, clearing and development are expected to continue, according to maps in the Comprehensive Plan (Lewis County, 2000). This development will continue to limit the amount of spotted owl habitat available in the area of the management circle, as well as contribute to the disturbance of potentially nesting spotted owls. Within CHU WA -53, training of troops is expected to continue in the future, as is maintenance of vegetation within the training areas in an early seral condition. While spotted owl habitat may develop in parts of the CHU in the future, and the possibility exists that owls may one day inhabit the area, they are unlikely to inhabit the immediate vicinity of the proposed ROW due to other ongoing activities. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6 -39 Section 6. Evaluation of Listed Species March 2000 rzji 6.18.6 Compliance with Recovery or Management Plans Because no activity will take place within 0.25 mile of a known nest site, no currently suitable spotted owl habitat will be removed, and the potential for the existing CHU to support spotted owls will not be altered by the fiber optic line, the project will be consistent with management plans for the spotted owl. 6.18.7 Conservation Measures Conservation measures are listed in section 3.5.5 of this document. 6.18.8 Determination of Effects Because no suitable habitat for the northern spotted owl will be altered or removed as a part of this project; construction, maintenance, and operation activities within potential spotted owl use areas are expected to be within ambient noise levels for the site; the only known spotted owl activity center associated with this project is greater than 0.5 mile from the proposed ROW; and, suitable habitat within the CHU has been surveyed with no owls found and detected, this project is expected to have "no effect" on the northern spotted owl. Because potentially suitable habitat within the CHU will neither be altered nor removed, and implementation of the fiber optic line will not prevent currently forested stands from developing into suitable spotted owl habitat, this project is expected to have "no effect" on designated critical habitat for the northern spotted owl. 6.19 MARBLED MURRELET Marbled murrelets are listed as threatened by the USFWS (57 FR 45337). The North American subspecies of marbled murrelet occurs form the Aleutian Islands south along the coast of Alaska, Washington, Oregon, and northern California (Carter and Erickson, 1988). Population declines have been attributed to fragmentation and loss of nesting habitat (Csuti et al., 1997), reduced food availability (Burkett 1995), over - harvesting of fish (Ainley et al., 1995), and direct mortality associated with gill -net fishing, predation, urbanization, and the effects of oil spills (Fry 1995; Carter and Kuletz, 1995; WDFW 1993). 6.19.1 Action Area The action area includes the project ROW, as described in Section 3.1, and any area where disturbance may occur within 0.50 mile from suitable murrelet habitat (61 FR 26264). 6.19.2 Marbled Murrelet Populations in the Project Vicinity There are no known occurrences of marbled murrelets within the proposed ROW (PHS data). The portions of the ROW in Oregon, and in Clark County and the southern half of Lewis Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington •'s..: atictir Biological Assessment 6 -40 Section 6. Evaluation of Listed Species March 2000 County in Washington, are greater than 50 miles inland from salt water and so will not be expected to provide suitable marbled murrelet habitat. Forested habitat along the remainder of the proposed ROW is not in a late successional condition and so is not expected to be utilized by marbled murrelets. The potential exception to this is the stands greater than 100 years old within the spotted owl critical habitat unit WA -53 on Fort Lewis. This potential habitat has been surveyed, however, and no marbled murrelets were detected. Additionally, growing conditions in the area result in an open canopy growth habit as opposed to the closed canopy cover murrelets prefer (Department of Defense 1993). This area was not identified as critical habitat for marbled murrelets by the USFWS. 6.19.3 Habitat Requirements and Ecology Murrelets typically nest in low - elevation old- growth and mature coniferous forests, usually within 50 miles of the coast (Csuti et al., 1997; Hamer, 1995). Murrelet nests are usually located high in older conifers with wide horizontal limbs, mistletoe, or deformities. Breeding occurs between late March and late September (61 FR 26257). The majority of murrelet nests have been found in large intact stands of old- growth forest (Miller and Ralph, 1995) although nests have been found in stands as small as 7 acres (Hamer and Nelson, 1995). Suitable habitat is defined as old - growth forest and mature forest with old- growth components [trees > 46 cm (32 inches) in diameter with large moss - covered branches (Ralph et • al., 1993)], and the percentage of old- growth tree crown cover appears to be an important factor associated with occupied sites (Miller and Ralph, 1995; Hamer and Nelson, 1995). Marbled murrelets feed in the marine environment and forage by pursuit diving. They will forage in marine waters at distances of 0.3 to 32 km from shore. They consume a diversity of prey consisting of fish and invertebrates, and will alternate food sources with season and abundance (61 FR 26258). 6.19.4 Designated Critical Habitat Critical habitat for the marbled murrelet was designated by the USFWS in 1996 (61 FR 26258). No designated critical habitat units occur within the vicinity of the proposed ROW, with the nearest CHU located approximately 40 miles from the proposed ROW. 6.19.5 Analysis of Effects 6.19.5.1 Direct Effects Because no marbled murrelets or potential murrelet habitat occur within the vicinity of the proposed ROW, no direct effects to marbled murrelets are expected in conjunction with the fiber optic line. Williams Communications, lnc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6 -41 Section 6. Evaluation of Listed Species March 2000 6.19.5.2 Indirect Effects Long -term maintenance of the proposed ROW in an early seral condition will preclude development of vegetation into murrelet habitat in the future. Much of the ROW occurs in existing rights -of way, however, and will not be managed with the objective of developing late successional habitat. The focus for vegetation management on Fort Lewis is to accelerate the development of existing forested areas into late successional condition and maintain areas of existing forest. Because no new forest clearing will occur in conjunction with this project in Fort Lewis, this project will not alter the potential for late successional habitat to occur in the future. For these reasons, no indirect effects to marbled murrelets are expected as a result of this project. 6.19.5.3 Interdependent and/or Interrelated Effects Because neither marbled murrelets nor their habitat occurs within the vicinity of the proposed ROW, no interdependent or interrelated effects are expected to occur as a result of this proj ect. 6.19.5.4 Cumulative Effects and Environmental Baseline While several jurisdictions are implementing watershed - related projects and restoration activities in the project ROW, no specific non - federal actions are known that will cause significant effects, when considered collectively with this project. 6.19.6 Compliance with Management or Recovery Plans Because this project will not affect designated critical habitat for marbled murrelets and will not alter or remove any primary constituent elements of marbled murrelet habitat, this project will be in compliance with the marbled murrelet recovery plan. project. 6.19.7 Conservation Measures There are no conservation measures specific to marbled murrelets associated with this 6.19.8 Determination of Effect Because no designated murrelet critical habitat occurs within 0.25 mile of the proposed ROW, no murrelets sightings have occurred within the project vicinity, and murrelet surveys in potential suitable habitat have failed to locate nesting murrelets, marbled murrelets are not expected to occur in the project ROW, and this project is expected to have "no effect" on marbled murrelets or on marbled murrelet designated critical habitat. Williams Communications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 6 -42 Section 6. Evaluation of Listed Species blarch 2000 6.20 ALEUTIAN CANADA GOOSE The Aleutian Canada goose is currently listed as threatened (55 FR 51106) by the USFWS. The species was first listed as endangered in 1967 (32 FR 4001) and down- listed to threatened in 1990. The species is currently being considered for removal from the list of threatened and endangered species. Declines in the Aleutian Canada goose population were attributed to the introduction of predators (e.g., foxes) to its breeding habitat. Hunting along the Pacific Flyway and habitat loss on its migration and wintering range also contributed to the population decline. Management efforts to reduce and eliminate foxes in the breeding habitat, and closure of hunting on principal wintering and migration habitats have been successful. 6.20.1 Action Area The action area for the Aleutian Canada goose includes the project ROW, as described in Section 3.1, and known migration stopover areas. 6.20.2 Aleutian Canada Goose Populations within the Project Vicinity According to the Oregon Natural Heritage database, no Aleutian Canada geese have been documented within 2 miles of the ROW. Although winter range and spring and fall staging areas have been identified on Sauvie Island, and in Multnomah and Columbia counties, the Aleutian Canada goose occurs only sparingly in these areas (Marshall et al., 1996). Coastal regions of Oregon provide stopover areas for migrating geese. According to the WDFW PHS (1999), there are no known migratory habitats within 60 miles of the right -of -way. The nearest identified regular stopover for migrating Aleutian Canada geese, approximately 60 miles west of the right -of -way, is the Willapa National Wildlife Refuge. Individuals and small flocks of Aleutian Canada geese have been documented 3 miles west of the right -of -way, in the Ridgefield National Wildlife Refuge (Hays 1997). On rare occasions, during migration, Aleutian Canada geese will stop over at the Lake Vancouver area intermixed with Canada geese (Brian Calkins pers. comm.). According to area biologists, the pasture area crossed by the right -of -way is outside of the waterfowl use area (Brian Calkins, pers. comm.). Habitat Requirements and Ecology. 6.20.3 Habitat Requirements and Ecology Oregon and Washington provide migratory habitat for Aleutian Canada geese. In September, the geese migrate to wintering grounds in California, typically stopping along coastal areas of Washington and Oregon. The Willapa National Wildlife Refuge and surrounding farms comprise the primary migratory habitat for Aleutian Canada geese in Washington. Nestucca and Netarts bays, Three Arch Rocks, Haystack Rock, and south to Bandon and Brookings along the Oregon coast provide primary migratory habitat in Oregon. Williams Communications, Inc.

Evaluation of Listed Species March 2000 ;Mgtbe•sn�� -- -- __ .-.. .+_✓r.a�.xa+Y -..NCY R!'1:!I; �Y El'*4 tl;•n Pasture and cropland in both Washington and Oregon provide potential migratory stopover locations for Aleutian Canada geese. Forage habitat includes meadows, agricultural lands, upland, and marsh environments (Csuti et al., 1997). 6.20.4 Designated Critical Habitat The USFWS has designated no critical habitat for Aleutian Canada goose. 6.20.5 Analysis of Effects 6.20.5.1 Direct Effects Because Aleutian Canada geese are not known to utilize areas within 2 miles of the right - of -way, no direct effects are expected to flocks of geese at known migratory stopovers. However, during migration (September to December) potential disturbance to individuals or small flocks may occur in scattered fields along the right -of -way. Construction activities associated with installing fiber optic line and building OP -AMP stations have the potential to scare geese from resting and foraging in associated fields. 6.20.5.2 Indirect Effects Where vegetation maintenance activities will occur adjacent to agricultural fields, wetlands, and marshes the potential to disturb migrating individuals and small flocks may occur. Disturbance will be associated with equipment and increased human activity used to maintain vegetation. 6.20.5.3 Interdependent and /or Interrelated Effects No interdependent and/or interrelated actions, other than maintenance activities, will occur. Effects of maintenance activities are described under indirect effects. 6.20.5.4 Cumulative Effects and Environmental Baseline While several jurisdictions are implementing watershed - related projects and restoration activities in the project ROW, no specific non - federal actions are known that will cause significant effects, when considered collectively with this project. 6.20.6 Compliance with Recovery or Management Plans Because the fiber optic line occurs outside of areas designated for Aleutian Canada geese, the project will be consistent with the USFWS Recovery Plan.

There is no proposed or designated critical habitat, no known migratory stopover habitat (within 60 miles of the right -of -way), no individuals have been documented within 2 miles of the right -of -way, and Aleutian Canada geese are not expected to occur in the project ROW. Therefore, a "no effect" determination is made. 6.21 COLUMBIAN WHITE- TAILED DEER Currently, the Columbian white- tailed deer is listed as an endangered species by the USFWS (32 F R 4001). Deer populations were historically abundant throughout wet meadows, grasslands, and oak woodlands in Oregon and southern Washington (64 FR 59729). Decline in Columbian white -tail deer populations has been attributed to the drainage of wetlands and , clearing of seasonal cover. Habitat loss continues to be a limiting factor for the Columbian white - tailed deer and the Revised Federal Recovery plan (USFWS 1983) suggests habitat protection to achieve delisting the species. 6.21.1 Action Area The action area includes the project ROW, as described in Section 3.1, and any areas where Columbian white - tailed deer are protected or have been observed. 6.21.2 Columbian White - tailed Deer Populations within the Project Vicinity In Oregon, Columbian white - tailed deer inhabit a few islands in the Columbia River and Oregon white -oak woodlands around Roseburg (Csuti et al., 1997). The Columbia River population is known to use the floodplain of the Lower Columbia River between Karlson Island (at River Mile 32) and Wallace Island (at River Mile 50) (Marshall et al., 1996). The Columbia River population resides approximately 60 miles from the right -of -way at the St. Johns Bridge. An observation of a lone Columbian white - tailed deer was recorded at the Burlington Bottoms habitat area approximately 4.5 miles west of the St. Johns Bridge. In Washington, Columbian white - tailed deer populations have been identified more than 60 miles away from the project vicinity. The lower Vancouver area is within the historic range of sightings but the species does not currently occur there (Miller, pers comm.). There were no concerns regarding Columbian white - tailed deer in the vicinity of the right -of -way (Miller, pers comm.). Williams Communications, Inc. Fiber Optic Line System Installation Project Portland. Oregon to Seattle, Washington Biological Assessment 6 -45 Section 6. Evaluation of Listed Species March 2000 :14 IA •a LJ 6.21.3 Habitat Requirements and Ecology The Columbian white - tailed deer is considered a floodplain species. Populations occur mainly in riparian zones, although in Oregon they have been documented in oak savannah habitat. They are primarily grazers, foraging on spring grasses and herbaceous plants (Marshall et al., 1996). Columbian white - tailed deer forage along edges with brushy cover or pastures with forest cover nearby (Csuti et al., 1997; Marshall et al., 1996). Although active throughout the year, the Columbian white - tailed deer home range may only reach 0.16 square mile (Csuti et al., 1997). 6.21.4 Designated Critical Habitat No critical habitat designation for Columbian white - tailed deer has been determined by the USFWS. 6.21.5 Analysis of Effects 6.21.5.1 Direct Effects Because there are no documented resident Columbian white - tailed deer populations within 60 miles of the right -of -way, no direct effects are expected to occur. Therefore, no conservation measures have been outlined. 6.21.5.2 Indirect Effects No indirect effects associated with this project are expected to occur. Vegetation maintenance, as described in Appendix D, will occur in areas adjacent to agricultural fields, wetlands, and marshes. These activities will cause no indirect effect to the population of Columbian white- tailed deer 60 miles away. 6.21.5.3 Interdependent and /or Interrelated Effects No interdependent and/or interrelated actions, other than maintenance activities, will occur. 6.21.5.4 Cumulative Effects and Environmental Baseline While several jurisdictions are implementing watershed - related projects and restoration activities in the project ROW, no specific non - federal actions are known that will cause significant effects, when considered collectively with this project.

The ESU comprises cutthroat trout in the Columbia River and its tributaries downstream from the Klickitat River in Washington and Fifteenmile Creek in Oregon (inclusive), and the Willamette River and its ' tributaries downstream from Willamette Falls. It also includes cutthroat trout in Washington coastal drainages from the Columbia River to Grays Harbor, inclusive. Trends in anadromous adults and outmigrating smolts in this ESU are all declining (Johnson et al., 1999). The adult migration occurs from July to September, peaking in July and August, and juvenile outmigration peaks in May. The run is considered depressed (WDF/WDW 1993). 7.1.3 Habitat Requirements and Ecology Adults migrate to freshwater in summer, and spawn from December through May, peaking in February. Fry emerge from the gravel substrate by mid -July, and juveniles will rear in freshwater for an average of 2 years before migrating to Puget Sound. Many stocks are believed to migrate only as far as estuarine areas as adults, so these areas can be important to their survival. Cutthroat trout have evolved to exploit habitats least preferred by other salmonid species (Johnston 1981). Sea -run cutthroat trout do not over - winter in the ocean and only rarely make long extended migrations across large bodies of water. They migrate in the nearshore marine habitat and usually remain within 10 km of land (Sumner 1972; Giger 1972; Jones 1976; Johnston 1981). Key habitat features include channel stability, clean spawning substrate, abundant and complex cover, cold temperatures, and lack of barriers that inhibit movement and habitat connectivity. 7.1.4 Designated Critical Habitat NMFS has found that critical habitat for this species is not now determinable. Prior to proposing critical habitat, geographic areas must be identified as well as areas outside the current species range. Williams Communications. Inc.

Reasons for the decline of the species are unclear, however, introduction of bullfrogs and loss of habitat have negatively impacted the spotted frog (Rodrick and Milner, 1991). 8.1.1 Action Area The action area for the Oregon spotted frog is the project ROW, as described in Section 3.1, and streams and rivers downstream of where stream drillings will occur, because E,.4. construction and/or maintenance disturbance could affect water quality and, therefore, Oregon spotted frog habitat. PA 8.1.2 Oregon Spotted Frog Populations within the Project Vicinity No Oregon spotted frogs were identified during field surveys conducted by Jones & Stokes. According to the WDFW PHS database, there are no known populations or sightings of Oregon spotted frog within the vicinity of the project ROW. In Washington west of the „a Cascades, Oregon spotted frogs are known from only three sites in Thurston and Klickitat counties. Although Clark County is part of the Oregon spotted frog historic range, there is no compelling evidence of recent occurrences of Oregon spotted frogs near the project ROW in Clark County (McAllister, pers. comm.). According to the WDFW PHS database, the nearest population occurs in Thurston County 5.3 miles northeast of the right -of -way. 8.1.3 Habitat Requirements and Ecology The Oregon spotted frog is endemic to the Pacific Northwest and closely associated with marshy edges of ponds, lakes, and other wetlands (Nussbaum et al., 1983). Oregon spotted frogs inhabit almost entirely aquatic environments, leaving wetlands for only short durations. They are found within forested landscapes, in riparian forests, and in areas with dense shrub cover. Spotted frogs are active in lowland habitats from February to October. Breeding occurs during late winter or early spring. Areas of shallow, still, or slow - moving water with sparse, emergent vegetation are preferred for egg laying. Research suggests that the minimum marsh size capable of sustaining an Oregon spotted frog population is 9 acres (McAllister and Leonard, 1997). On dry days Oregon spotted frogs will feed on invertebrates, generally within 1.6 feet of shore. They may move from permanent water to feed in wet vegetation or puddles during rain. Williams Caninunications, Inc. Fiber Optic Line System Installation Project Portland, Oregon to Seattle, Washington Biological Assessment 8 -1 Section 7. Evaluation of Candidate Species March 2000 Larval frogs feed on scavenged plant and animal material, aquatic algae, and vascular plants (Nordstrom and Milner, 1997). 8.1.4 Designated Critical Habitat The USFWS has designated no critical habitat for Oregon spotted frog. 8.1.5 Analysis of Effects No known population or sighting of Oregon spotted frog occurs within the vicinity or downstream of the project ROW. 8.1.5.1 Direct Effects Because the Oregon spotted frog does not occur within 5 miles of the project right -of- way, no direct effects are expected to occur. lithe species did occur, activities within habitat could cause direct stress or injury to frogs (including all life history stages). Activities in adjoining habitat could produce sediment or hazardous substance spills, which if conveyed to aquatic habitat could also cause direct stress or injury to frogs. Because the line will be installed underground through deep drilling under flowing streams and rivers, as described in conservation measure OS1 (Section 3.5.5), vegetation associated with Oregon spotted frog breeding, wintering, or foraging will not be disturbed. Additional impacts to Oregon spotted frog foraging, breeding, and wintering habitat will be minimized through application of conservation measures 0S2 -0S4. These measures will ensure that entry to potential Oregon spotted frog habitat is avoided, and sediment or hazardous substance impacts are minimized. 8.1.5.2 Indirect Effects Indirect effects will be similar to direct effects in terms of the nature of the impact, and will result during the course of facilities maintenance. Thus, potential indirect effects will be much less frequent and less extensive than direct effects. Indirect effects will be avoided or minimized using the same conservation measures used for direct effects. 8.1.5.3 Interdependent and /or Interrelated Effects No interdependent and/or interrelated actions, other than maintenance activities, will occur. Effects of maintenance activities are described under indirect effects. 8.1.5.4 Cumulative Effects and Environmental Baseline While several jurisdictions are implementing watershed - related projects and restoration activities within the project ROW, no specific non - federal actions are known that will cause significant effects, when considered collectively with this project.

Biological Assessment 8 -2 Section 7. Evaluation of Candidate Species March 2000 Because the project will not significantly alter wetland hydrology, water quality, or plant communities, the project will not add to cumulative effects in the action area. 8.1.6 Compliance with Recovery or Management Plan There is no recovery or management plan for the Oregon spotted frog in this area. 8.1.7 Conservation Measures Conservation measures are listed in Section 3.5.5 of this document. 8.1.8 Determination of Effect The fiber optic line is not expected to adversely impact Oregon spotted frogs or their habitat. Conservation measures will be imposed to minimize general environmental impacts. Because there are no areas designated as critical habitat, no removal of key habitat features or suitable habitat will occur, and no known Oregon spotted frog population exists within 5 miles of the right -of -way, the fiber optic line "may impact, but is not likely to adversely impact" Oregon spotted frog. 8.2 COHO SALMON: THE LOWER COLUMBIA RIVER/SOUTHWEST WASHINGTON ESU 8.2.1 Action Area Same as for the Lower Columbia River chinook salmon ESU (Section 6.2.1). 8.2.2 Coho Stocks within Project Vicinity The Lower Columbia River /southwest Washington coho salmon ESU was designated as a candidate species on July 25, 1995 (60 FR 38011). The Lower Columbia River ESU is defined as the Columbia River and its tributaries below Bonneville Dam, exclusive of the Willamette River. Current trends show no change from historical abundance information; however, the population is supported mainly by hatcheries. Juvenile and adult coho of the Lower Columbia River ESU may migrate through, spawn, or rear in the project ROW at the Columbia River. Adult migration occurs from August to December, peaking in October; the juvenile outmigration peak occurs in May. The run is considered depressed (WDF /WDW 1993). 8.2.3 Habitat Requirements and Ecology Adults begin migration into freshwater to spawn in late summer or early fall. Coho spawn from November to January. Habitat requirements include cool oxygen -rich water and Williams Communications, Inc.

Woody material (such as low shrubs) will not be removed, but rather placed back on the ROW with topsoil to provide a seed source and organic matter. • Other measures to restore or improve surface drainage measures already existing on the right of way might include tightlining discharge from water bars and diverting or collecting surface water coming on to the right -of -way and tightlining on the onflow to below the slope. • Where sediment could be transported onto a public road surface or other paved area by equipment or vehicles accessing or leaving the construction site, sediment will be removed from the road immediately by shoveling or sweeping and transported to a sediment - controlled disposal area. • Inspections of site conditions and the BMPs will be conducted prior to anticipated storm events to identify areas that may contribute to sediment discharge; corrective actions will be made as required. • All erosion and sediment control measures will be checked within 24 hours of each 0.5 -inch or greater rainfall event and every 14 calendar days during October 15 through April 15, up until the time that site stabilization is achieved. During April 16 through October 14, the inspections will be conducted every 30 days. During extended storm events, inspections will be conducted at least once every 24 hours. • Inspection reports will be completed after each inspection and included in the project file. Ineffective temporary erosion control measures will be repaired or replaced as soon as possible but no later than 24 hours after identification. • Williams will retain completed inspection forms for at least 3 years. • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in place until the ROW is permanently stabilized as defined by the general permit. Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. ll'illiwns Communications, Inc, Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington .9 LY1tii ..`+Yeuit tafJ' vx'ai: 'kn.8'3.4 " -.- - -y[y.yet.Y E -3 Appendix E Best Management Practices March 2000 • Significant amounts of sediment that leave the ROW will be cleaned up within 24 hours of deposition and either (1) placed back onto the site and stabilized or (2) properly disposed. ■ Equipment, materials, and workers must be available for rapid response to BMP failures and emergencies. • Salvaged topsoil will be spread evenly over all areas to be reclaimed. • Following replacement, topsoil will be stabilized against wind erosion by use of mulches, surface soil sealers, and/or erosion control fabric. • Minimum grading will be conducted to establish staging areas. • Locate staging areas in existing contractor yards; commercial areas used for storing and maintaining equipment; previously cleared, graded, or paved areas; or other level areas where grading and vegetation clearing is not required. • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid substantial soil loss and displacement. • Install baffle boards where needed on steep slopes. • Where necessary, armor bank slopes with riprap. ■ Silt fences or straw bale dikes will be used to intercept and retain small amounts of sediment carried by sheet flow from disturbed areas during construction activities and to prevent this sediment runoff from leaving the project site. • Silt fencing or straw bale dikes will be placed along the base of fill slopes and above cut slopes. If the side slope cut is longer than 200 feet, an erosion control blanket will be used with reseeding. The cut slope will not exceed 1.5:1, and the fill slope will not exceed 2:1. • Any soil stockpiled next to trenches that are subject to erosion will either be located on { the upslope side of the trench, protected using straw bale dikes or silt fences, or covered with plastic, as appropriate. • The contractor must have on hand a minimum of eight straw bales at all times for emergency sediment containment purposes. • Repair existing roads upon completion if additional disturbance is created from fiber optic line installation construction activities. ■ Installation of steel casing will require standard cut -and -cover trenching techniques. Trenches should be backfilled with select backfill and compacted. Trench plugs should be installed periodically within the trench to prevent piping of the backfill and to limit Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington ,t4re .c' : ,� Appendix E E -4 Best Management Practices March 2000 Olt groundwater movements. Water trapped at the trench plugs should be captured in a French drain and tightlined below the right -of -way and off the potential landslide area. • In some landslide areas it may be possible to span the affected area by stringing the fiber optic conduit and line aboveground on poles. Poles within the landslide mass may also be feasible where the landslide plane is below the depth of embedment of the pole, allowing the pole to move with the landslide mass. z w • Site visits should be performed for all active and potentially active landslide areas. Site visits to potentially active landslide areas are necessary to confirm preliminary evaluation o p that these areas are not currently active as well as to mark the limits of areas where w special construction will be required. LLI �w • Where HDPE conduits have been installed by plow, the resulting furrowed soil will be w o leveled by compaction. For installation by drilling, any extra excavated material from the g boring will be hauled to an authorized offsite disposal area. For installation by open -cut ?, trenching, the trench will be backfilled. I a • All temporary soil erosion control measures will be removed within 30 days after final Z ROW stabilization is achieved. Trapped sediment and disturbed soil areas resulting from z 0 the removal of temporary measures will be stabilized to control further erosion and g sedimentation.

These parties will be notified within 24 hours of an accidental find. • Specific OAHP instructions concerning an accidental find resulting from the notification(s) described above will be followed on a case -by -case basis. At a minimum, sufficient archaeological work will be performed on the accidental find location to stabilize deposits, protect deposits from scavengers or looters, and to collect readily available samples (e.g., for radiocarbon dating) which may help pinpoint the age of deposits or, in the case of burials, the presence of data which may serve to identify lineal or cultural descendants. • The owner and its cultural resources consultant will consult with OAHP to follow through on the course of action selection to comply with Section 106. This may require development of an MOA or implementation of actions involving the find that satisfy Section 106, and may involve consultation with Native American groups.

The owner recognizes the importance of providing careful and respectful treatment of human remains recovered as an accidental find or as part of an archaeological investigation. If the proposed undertaking is not on Federal or Native American lands, consultation prior to implementation is not required. In the event of an accidental find of human remains, the owner will contact OAHP for appropriate Native American groups with which to consult. In coordination with OAHP and all interested parties, a decision will be made for the treatment of the remains. SPILLS AND MATERIALS MANAGEMENT • All onsite vehicles will be monitored for petroleum leaks, and all spills will be cleaned up immediately upon discovery. • Store hazardous materials, chemicals, fuels, and oils and fueling of construction equipment a minimum of 200 feet from any drainage, wetland, water supply, well, spring, or other water feature. ■ Any hazardous waste material generated by project construction and operation will be disposed of in the manner specified by local and state regulations or by the manufacturer. Site personnel will be instructed to be aware of this requirement. ■ Keep cleanup materials and equipment readily available onsite, either at an equipment storage area or on the contractor's trucks. ■ Locate equipment wash stations on level (0 to 2% slope), vegetated areas at least 200 feet from the margins of drainages or wetlands. Washing will be conducted in a manner that avoids runoff from the washing area. • Where paved surface restoration requires the use of concrete, a concrete washout will be used to rinse or clean tools. The securely anchored washout, constructed using a straw bale perimeter and plastic sheeting ground cover, will be adequately sized to contain all material washed into it. Following the completion of activities requiring concrete resurfacing, all contents contained in the washout will be properly disposed of offsite. ■ Spills will be documented and a record of the spills will be kept with the SWPPP. If a spill occurs that is reportable to the federal, state, or local agencies, the resource monitor is responsible for the reports. • All waste material will be collected and stored in a secure container and removed from the project ROW. The waste container will be inspected regularly and the contents will be disposed of properly by the owner. No waste oil or other petroleum -based products will be disposed of onsite (e.g., buried, poured), but will be removed offsite for proper Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington E -6 Appendix E Best Management Practices March 2000 disposal. Litter generated by the construction crew will be picked up and properly disposed of on a daily basis. • All sanitary wastes will be collected from portable units as required and properly disposed of offsite. z • When boring requires the use of drilling mud, such as bentonite, no discharge of excess material or site runoff will be allowed into drainages or wetlands. Slurry tanks will be sized to hold excess material completely so that there is no spillage. The casing pipe 6 = entry point will be appropriately enclosed and equipped with a sump pump to reclaim or v p discharge excess slurry or discharge it to a reuse or disposal tank. Earth spoiled by co w drilling slurry will be removed and disposed of by the contractor, and the ROW will be L refilled with clean material. Upon completion of construction, the ROW will be restored N u_ to a condition equal to or better than its original condition. W o gQ VEGETATION = d • All steep, unstable slopes will be left vegetated whenever possible. z ►_- h— O z • Compaction and grading of soils close to mature trees should be avoided to prevent j U� O 92 • Limited removal and disposal of trees and/or brush within the construction zone and as o E▪ _ per engineering drawings and typicals is expected. If required, a subcontractor will cut ▪ 0 brush and trees as needed to create a clean path up to 10 feet wide for construction equipment access. Where this is needed, all trees and shrubs will be cut flush with the Z ground (existing ground). Some downed trees may be left on site to provide habitat for small mammals, birds and insects and to provide nutrient cycling processes. Smaller p F- limbs and brush may be chipped to aid erosion control and to reduce fire hazard z • Mixing of topsoil with subsoil will be prevented by using topsoil segregation methods. When implementing these methods, topsoil will be windrowed separately from subsoil. Topsoil will be stripped from the subsoil storage area and stored along the edges of the corridor with other stockpiled topsoil. For deep soils (that is, in floodplain and stream terraces), at least 12 inches of topsoil will be segregated. Where soils are shallow to bedrock or have stony subsoil, all available topsoil will be separated from coarser parent material. damage to root systems. • Topsoil and other suitable growing media will be used to restore suitable plant growing conditions after construction is completed. • Final stabilization for the purpose of terminating coverage under the general permit is achieved when all soil - disturbing activities are completed and either (1) a uniform vegetative cover of 70% has been established or (2) equivalent stabilization measures (e.g., erosion control blankets) have been installed. • All groundbreaking disturbances will be seeded with native species for erosion control. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington E -7 Appendix 6 Best Management Practices March 2000 • IS I • Revegetation using native seed mixtures and approved mulch will be performed on all areas disturbed by project activities. Temporary erosion control measures will be left in f'-41 place until the ROW is permanently stabilized as defined by the general permit. 111 Following completion of construction and planting activities, the construction inspector will conduct periodic ROW reviews to ensure that vegetation establishment is satisfactory. If vegetation cover is not adequate, special steps to correct problems will be implemented, such as overseeding, mulching, or the use of erosion control blankets. • Seeding or mulching will be done only in those portions of the right -of -way that were vegetated prior to the start of construction. Seeding or mulching will be conducted if construction halts for more than 21 days during the rainy season (i.e., October 15 through April 15). WATER QUALITY • Soil disturbances on slopes of more than 40% will be avoided as much as possible. • The use of biodegradable matting will be used only in areas of steep slopes that are near critical areas (e.g., streams). • Topsoil will be preserved and replaced to the greatest extent possible to maximize the effectiveness of revegetation efforts. i1 • Erosion and sediment controls will be used during and after construction, including siltation fences, certified weed -free hay bales, interceptor dikes, sediment traps to avoid substantial soil loss and displacement. • Where fertilizers are used, they will be applied only in the recommended amounts. Once applied, the fertilizer will be worked into the soil to limit exposure to storm water. Fertilizer spills will be cleaned up immediately. • Watering trucks or other appropriate dust - abatement measures will be used to control dust generated during construction as required to prevent fugitive dust emissions. Applying water to the point that runoff occurs will be avoided. WETLANDS • Identify sources of sediment and other pollutants that can affect the quality of storm water discharges. • Under no conditions will soil or other material be intentionally washed into storm drainage systems, drainages, or wetlands. • Focus on controlling erosion rather than controlling sedimentation. Williams Communications, Inc. Fiber Optic Cable System Installation Project Portland, Oregon to Seattle, Washington E -8 Appendix E Best Management Practices March 2000 • All staging areas for wetland crossings will be kept at least 150 feet away from the wetland edge, when possible. • No refueling or servicing will be done within a wetland buffer. Absorbent material or drip pans will be placed underneath the equipment to contain leaks or spills. • Construction matting will be used for work in all saturated or inundated wetlands (required to get a Nationwide 12 Corps Permit). • Wetland contours will be restored to original conditions to prevent any damming of water flow across the wetland. If the original contours were irregular (e.g., hummocks), the restoration should not provide an unnatural watercourse that causes the area to dewater, thereby disrupting the natural wetland hydrology. • All handholes will be located outside of wetland areas wherever possible. f . No activity will substantially disrupt the movement of those species of aquatic life indigenous to the waterbody. ,gar t • Crossing of wetland areas by construction equipment or vehicles solely for the purpose of accessing other parts of the project construction right -of -way will be prohibited unless the only means of access is through the wetland. • If standing water or saturated soils are present, the contractor will use wide -track or balloon -tire equipment or operate normal equipment on equipment pads to perform the ,4 necessary construction activities. • All timber bridges, fords, culverts, and prefabricated equipment pads will be removed on completion of any construction activities. `-"1 • During construction, will directionally drill all perennial/intermittent/seasonal drainages ■w that support sensitive resources and have flowing water at the time of construction. (The environmental monitor will determine which drainages meet the criteria.) • Locate boring areas at least as far as jurisdictional requirements stipulate from the water's edge with a temporary work space on each side of the channel for equipment and staging.
