The parcel is also proposed to be short platted, with the western portion of the site to be leased to Insurance Auto Auction, the property owner on the north, for the parking of salvaged automobiles. The site has been under industrial use since the 1930s. Most recently, Rhone- Poulenc operated a vanillin manufacturing facility that was closed in 199 L Historic releases of hazardous substances occurred at the site. Released materials include caustic soda, toluene, mineral oil, PCBs and copper. Corrective action for the historic releases is being addressed under a Resource Conservation and Recovery Act (RCRA) Administrative Order on Consent issued by the U.S. Environmental Protection Agency, Region 10 (Docket # 1091= 11= 20- 3- 8(h)). 2. POLICIES OF THE SMA /SMP: 1. Emphasis should be given to development within already developed areas. Response: The project is located in an area that is already intensely developed with other industrial /manufacturing uses; the site was formerly used to manufacture vanillin. Steven M. Mullet, Mayor The King County Shoreline Regulations are applied as the site is in an area annexed to the City of Tukwila from unincorporated King County which is not included yet in the City's Shoreline Master Program. As a result, the policies and regulations of the Shoreline Master Program for King County, adopted May 1, 1978, continue to apply. The site is designated Urban. The following Urban Environment general policies apply to development in the Urban Shoreline: C I, Page 1 of 9 05/22/2006 4:31:00 PM q: \David -Rhone Poulenc \L05 -050 shoreline Staff Rpt.doc__ 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 =431 =3670 • Fax: 206 = 431 -3665 L05 -050, Davis Properties -Rhone Poulenc Site Shoreline Substantial Development Permit May 22, 2006 • • 2. Priority should be given to shoreline dependent and water oriented uses over other uses. Uses which are neither shoreline dependent or water oriented should be discouraged except for residential. Response: While there is a Port of Seattle slip adjacent to the property on the south, the proposed uses will not use the slip. 3. Emphasis should be given to developing visual and physical access to the shoreline in the Urban Environment. 4. To enhance the waterfront and insure maximum public use, industrial and commercial facilities should be designed to permit pedestrian waterfront activities consistent with public safety and security. S. Multiple use of the shoreline should be encouraged. Response: The nature of the proposed development, auto salvage parking and warehouse /office with associated truck traffic is not conducive to visual and physical access; landscaping will be used to screen the parking from view of the shoreline, both on the western and southern portions of the site. 6. Redevelopment and renewal of substandard areas should be encouraged in order to accommodate future users and make maximum use of the shoreline. Response: The site is being redeveloped for industrial uses after standing unused for over 10 years. The western portion of the site contains contaminated soils and is subject to a consent decree regulating its clean up. 7. Aesthetic considerations should be actively promoted by means of sign control regulations, architectural design standards, planned unit development standards, landscaping requirements and other such means. Response: As noted earlier, landscaping will be used to help screen the parking from view from the shoreline; the warehouse /office structure will be reviewed under Administrative Design Review 8. Development should not significantly degrade the quality of the environment, including water quality and air quality, nor create conditions which would accentuate erosion, drainage problems or other adverse impacts on adjacent Environments. Response: Stormwater from the site will be collected and treated in two water quality stormceptors and then discharged via a 36 -inch King County stormwater pipe to the Duwamish Waterway. The building permit application will be required to include a design approval letter from the stormwater treatment manufacturer and a storm drainage maintenance schedule that clearly identifies who, what, when and how maintenance will be performed. This will be recorded on the title of the property. The site will continue to be monitored for contaminates per the Resource Conservation and Recovery Act (RCRA) Administrative Order on Consent issued by the U.S. Environmental Protection Agency, Region 10 (Docket .# 1091- 11- 20- 3- 8(h)).

SHORELINE REGULATIONS: • • Following are the relevant review criteria as contained in the King County Shoreline Regulations for the Urban Environment (King County Code, Chapter 25.16) as applied by the City of Tukwila. KCC 25.16.030 General Requirements. A. Nonwater related development-shall not be permitted waterward of the ordinary high water mark (OHWM). Response: The building to be constructed is located landward of the ordinary high water mark. B. ... (N)o structure shall exceed a height of thirty-five feet... Response: The building as currently designed does not exceed 35 feet in height. There are no residential areas adjacent to this site that would have shoreline views blocked by the warehouse construction. C. All development shall be required to provide adequate surface water retention and sedimentation facilities during the construction period. Response: Stormwater from the site will be collected and treated in two water quality stormceptors and then discharged via a 36 -inch King County stormwater pipe to the Duwamish Waterway. The building permit application will be required to include a design approval letter from the stormwater treatment manufacturer and a storm drainage maintenance schedule that clearly identifies who, what, when and how maintenance will be performed. There is an existing 36 -inch diameter storm water pipe that runs through the central portion of the project site that will be re- routed around the proposed building and used for the discharge point for the new catch basin, collection, and conveyance system, including a water quality feature to discharge off site into Slip No. 6. Flow control is not a requirement for this project as there is direct discharge into Slip No. 6 in the Duwamish Waterway. Temporary erosion and sediment control (TESC) will be implemented prior to construction on the site. D. Development shall maintain the first fifty feet of property abutting a natural environment as required open space. Response: This criteria is not applicable as the King County shoreline environment designation adjacent to this site is "Urban Environment." E. Parking facilities except parking facilities associated with detached single family and agricultural development shall conform to the following minimum conditions: 1. Parking areas serving a water related or a non -water related use must be located beneath or upland of the development which the parking area serves. CL Page 3 of 9 05/22/2006 5:12:00 PM q: \David -Rhone Poulenc \L05 -050 Shoreline Staff Rpt.doc L05 -050, Davis Properties -Rhone Poulenc Site Shoreline Substantial Development Permit May 22, 2006 • • Response: The applicant has requested a variance to allow 26 parking stalls to be located waterward of the proposed office /warehouse. Landscaping is proposed, as shown on Sheet L -2 of the landscaping plan, on the western and southern sides of the site to screen the parking from view of the water. A public hearing was held on May 9, 2006 before the City's Hearing Examiner on the parking variance request. On May 22, 2006 the hearing examiner approved the variance (see Attachment G). 2. Any outdoor parking area perimeter, excluding entrances and exits, must be maintained as a planting area with a minimum width of five feet. Response: The applicant has provided perimeter landscaping adjacent to the shoreline associated with the office /warehouse building. Additional landscaping is also shown on the western and southern edge of the site on the proposed landscaping plan, where parking will be provided for the Insurance Auto Auction yard. 3. One live tree with a minimum height of four feet shall be required for each thirty linear feet of planting area. 4. One live shrub of one gallon container size or larger for each sixty linear inches of planting area shall be required. Response: The Preliminary Landscaping Plan has provided the required number of trees and shrubs for the area associated with the office /warehouse building. Additional trees and shrubs have been provided on the western and southern edge of the site to screen the proposed parking area on the western portion of the site. S. Additional perimeter and interior landscaping of parking areas may be required, at the discretion of the director, when it is necessary to screen parking areas or when large parking areas are proposed. Response: As noted, the applicant is being required to provide additional landscaping on the western and southern edge of the site to screen the parking of the Insurance Auto Action vehicles. F. Water quality treatment in compliance with KCC Chapter 9.04 shall be required where stormwater runoff would degrade or add to the pollution of recipient waters or adjacent properties. Response: The project proposes to use two stormceptors on the downstream end of the project site, ultimately discharging into a 36 -inch King County stormwater pipe which runs southwesterly through the eastern portion of the site. This pipe discharges into the Duwamish Waterway. The stormceptors have been sized in accordance with Washington State Department of Ecology regulations, which require 80 percent total suspended solids removal and 91 percent of the annual flow treated at a minimum.

If Indian burials are encountered, TMC 18.50.110 requires that the remains not be disturbed and notification of the State Office of Archaeology and Historic Preservation (OAHP). The applicant will be required to provide a written commitment to stop work immediately upon the discovery of archeological remains and to consult with the OAHP. 4. COMPREHENSIVE PLAN SHORELINE POLICIES The site is located within the Manufacturing/Industrial Center along the Green/Duwamish River. The Tukwila Comprehensive Plan establishes the following priorities in this shoreline environment: The project area is already a part of an intensively developed industrial area along the Green/Duwamish River. The warehouse /office building restores an industrial use to a site which has been unused for over 10 years. The salvage automobile parking on the western portion of the site is an expansion of the adjacent use on the neighboring property on the north. 5. COMMENTS: • redevelopment of under - utilized areas and development of intensive commercial and industrial activities; • enhancement and restoration of access to the river; and • protection and restoration of natural environment features and riverbank characteristics, where compatible with development. CL Page 7 of 9 05/22/2006 4:31:00 PM q: \David -Rhone Poulenc \L05 -050 Shoreline Staff Rpt.doc L05 -050, Davis Properties -Rhone Poulenc Site Shoreline Substantial Development Permit May 22, 2006 One letter was received from the Cultural Resources Program of the Muckleshoot Indian Tribe (copy attached). The Tribe has identified this site as being in an area of high potential for archaeological discovery because there are previously identified archaeological sites and a traditional cultural place nearby. The Tribe requested that information be provided on whether native soils could be intersected by construction on site. Supporting documentation such as a comparison of construction plans and soil profile information was requested to show that construction would take place entirely within fill. The applicant has provided a response prepared by Geomatrix discussing the depth of fill on the western portion of this site (see Attachment B). Generally the site was filled at the time the Duwamish Waterway was dredged and created. The report prepared by Geomatrix states that there is dredged sand and silt is present in the upper 5 to 15 feet of the subsurface. A limited amount of excavation will be conducted to install underground storm sewers and an underground stormwater treatment unit. Installation of the stormwater system will require trenching at depths of 4 to 6 feet, within the depth of fill noted by earlier studies of the site. The deepest trenching will be for the collector lines running north -south in the eastern portion of the western parcel, which will be excavated to a maximum depth of about 7 feet below existing grade. The depth of fill in that area is 5 to 7 feet. The deepest excavation will be for installation of the Stormceptor water quality unit and the discharge piping running to the existing 36 -inch storm sewer entering the eastern end of Slip 6. This proposed excavation depth will be approximately 11 feet below existing grade. The Stormceptor will be installed at the southeastern corner of the western parcel. The report anticipates that the soil above and adjacent to the existing 36 -inch sewer line consists of fill. TMC 18.50.110, Archaeological/Paleontological Information Preservation Requirements applies to all zoning districts in the City. This portion of the code requires excavations into historically native soil, when in an area of archaeological potential shall have a professional archaeologist on site to ensure that all State statues regarding archaeological conservation/preservation are implemented. The applicant is required to provide a written commitment to stop work immediately upon discovery of archaeological remains and to consult with the State Office of Archaeology and Historic Preservation. This will be a requirement of the shoreline substantial development permit and the building permits issued for both the western and eastern portion of the parcel. 6. SEPA: 7.

SHORELINE PERMIT PROJECT NARRATIVE Davis Property and Investment 9229 East Marginal Way South, Tukwila, Washington Prepared by: Barghausen Consulting Engineers, Inc. August 2005 Our Job No. 10265 Response: No development is proposed waterward of the ordinary high water mark (OHWM). CRITERIA FOR PROJECT SUBJECT TO KING COUNTY SHORELINE REGULATIONS ATTACHMENT A RECEIVED rJAN - 0 4 2006 COMMUNITY DEVELOPMENT A. Non -water related development and residential development shall not be permitted waterward of the ordinary high water mark. 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. Response: A small portion of the proposed warehouse building is located within the shoreline jurisdiction. A transition for the height of the future building from the zoning - allowed 125 feet to the shoreline - allowed 35 feet would be difficult, incongruous to the development, and would not protect views of any residential properties. At this time, the height of the future building is unknown; however, the developer desires the flexibility to have a uniform building height of up to 125 feet, including the area within 200 feet of the Duwamish Waterway and/or Port of Seattle Slip No. 6, which are both regulated shoreline areas. C. All development shall be required to comply with K.C.C. chapter 9.04 to control runoff and to provide adequate surface water and erosion and sediment control during the construction period. Response: Runoff will be collected and treated on site as required. There is an existing 36 -inch- diameter pipe coursing southwesterly through the central portion of the project site that will be rerouted around the building and utilized for the discharge point for the new catch basin, collection, and conveyance system, including a water quality feature to discharge off site into Slip No. 6. Flow control is not a requirement for this project site since there is direct discharge into Slip No. 6 in the Duwamish Waterway. The method of water quality for this project site is to provide a stormceptor for each of the two basins on site, ultimately draining into the 36- inch - diameter storm drain discharging into Slip No. 6. Please refer to Section 4.0 of the Technical Information Report for the sizing calculations of the stormceptors. Temporary erosion and sedimentation control (TESC) plans are included in the plan set for this project. Please see the TESC plans for details of the TESC measures. D. Development shall maintain the first fifty feet of property abutting a natural environment as required open space. 10265.010.doc [IH/pj] • Response: The project is not located in a Natural shoreline environment, therefore this item does not apply. E. Parking facilities except parking facilities associated with detached single-family and agricultural development shall conform to the following minimum conditions: 1. Parking areas serving a water related or a non -water related use must be located beneath or upland of the development which the parking area serves. Response: A variance has been requested to allow 26 parking stalls located waterward of the proposed warehouse building. 2. Any outdoor parking area perimeter, excluding entrances and exits, must be maintained as a planting area with a minimum width of five feet. Response: Perimeter landscaping, with no dimension less than five (5) feet, is provided around the parking within the shoreline jurisdiction. 3. One live tree with a minimum height of four feet shall be required for each thirty linear feet of planting area. Response: Please see the enclosed Preliminary Landscaping Plans; the required number of trees are provided or exceeded with the design. 4. One live shrub of one - gallon container size or larger for each sixty linear inches of planting area shall be required. Response: Please see the enclosed Preliminary Landscaping Plans; the required number of shrubs are provided or exceeded with the design. 5. Additional perimeter and interior landscaping of parking areas may be required, at the discretion of the director, when it is necessary to screen parking areas or when large parking areas are proposed. Response: Screening and perimeter landscaping is provided that is expected to meet or exceed required levels of landscaping for the parking within the shoreline jurisdiction. F. Water quality treatment in compliance with K.C.C. chapter 9.04 shall be required where storm water runoff would degrade or add to the pollution of recipient waters or adjacent properties. Response: This project proposes to locate two stormceptors on the downstream end of the project site, ultimately discharging into a 36- inch - diameter pipe coursing southwesterly through the central portion of the project site, ultimately discharging to Slip No. 6 in the Duwamish Waterway immediately adjacent to the project site. The stormceptors have been sized in accordance with Washington State Department of Ecology requirements as allowed by the City of Tukwila on past projects that have been designed utilizing stormceptors. This requires 80 percent total suspended solids removal and 91 percent of the annual flow treated at a minimum. - 2 - 10265.010.doc [IH/pj) G. The regulations of this chapter have been categorized in a number of sections; regardless of the categorization of the various regulations, all development must comply with all applicable regulations. Response: The project is designed to conform to City of Tukwila and King County Shoreline regulations, with the exception of the requested variance for structure height and parking waterward of the proposed building in the shoreline jurisdiction. H. Development proposed in shorelines of the state 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 Response: There is currently not an existing King County or City of Tukwila trail system. 2. Part of the site is presently being used and has historically been used for public access. Response: No portion of the site has been historically used for public access. 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. Response: The site is not located on Lake Sammamish; therefore, this item does not apply. J. The regulations of this chapter are in addition to other adopted ordinances and rules.

Mrs. Lumb, ATENT B MUCKLESHOOZ CULTURAL RESOURCES PROGRAM 39015 172nd Avenue S.E. • Auburn, Washington 98092 -9763 Phone: (253) 939 -3311 • FAX: (253) 876 -3312 oBrer6liS coMmou T On behalf of the Cultural Resources Committee, I have reviewed the information sent on 01/27/06 regarding the building and parking stalls at 9229 East Marginal Way South, Tukwila, and have the following comments. The 9229 East Marginal Way South property is an area the Tribe has flagged as high potential for archaeological discovery. The project area location is one that the Tribe considers to have a high probability for archaeological resources, because there are previously identified archaeological sites and a traditional cultural place nearby. Although the proposed project area appears to be previously disturbed, I cannot tell from the information provided whether the proposed construction could intersect native soils on -site. If that is a possibility, then we request that an archaeological study be conducted of the project area to determine the best means of identifying and protecting archaeological resources that may be uncovered during construction., If the applicant believes that construction would take place entirely within fill, we request supporting documentation, such as a comparison of construction plans and soil profile information. Information regarding previous surveys and recorded archaeological sites is available from the Office of Archaeology and Historic Preservation, in Olympia. The Cultural Resources Program does not represent the Wildlife Program and the Fisheries Program which are separate departments under the Muckleshoot Indian Tribe. Please contact these deparunents separately for their input on this project. We appreciate the effort to coordinate with the Muckleshoot Tribe prior to site preparation. The destructive nature of construction excavation can often destroy a site and cause delays and unnecessary expense for the contractor. If you have any questions, please contact me at 253- 876 -3272.

Your comment #6 states that a work plan for addressing the contamination on the eastern portion of the site was included –1 did not find that enclosure. Response: Six copies of the Draft East Parcel Cleanup Work Plan prepared by Geomatrix Consultants, Inc., dated November 2005 are enclosed. 8. Your comment #12 states that the Operation, Monitoring, Inspection and Maintenance Plan was included —1 did not find that enclosure. Response: Please see the enclosed Revised Operation, Monitoring, Inspection, and Maintenance Plan prepared by Geomatrix Consultants, Inc., dated February 2006. 9. Is there a contingency plan for relocating the wells after re- paving if using the metal detector does not work? Response: Several precautions have been taken to ensure that monitoring wells specified for continued monitoring will be returned to service after completing redevelopment of the western parcel. In addition to placing the metal plates over the wellheads, the location of each well has been surveyed by a licensed surveyor. If attempts to locate a buried well using a metal detector are unsuccessful, the known location will be surveyed. The metal detector and a GPS locator will be used initially to locate the wells after repaving has been completed. If neither the metal detector nor the survey can successfully locate a well, Container Properties will work with the EPA to resolve groundwater monitoring issues. Please note that the EPA has formally approved the redevelopment plan. An Approval with Modifications (enclosed) was issued by the EPA on March 29, 2006.

Geomatrix Memorandum Ivana Halvorsen, Barghausen Larry McGaughey John Long CC: Gary Dupuy TO: FROM: SUBJECT: Depth of Fill at Former Rhone- Poulenc Site This memorandum discusses the depth of fill materials in the western portion of the former Rhone- Poulenc facility located at 9229 E. Marginal Way South, in Tukwila, Washington. The portion of the site proposed for installation of a new stormwater system is referenced in this memorandum as the West Parcel. Plans and applications have been filed with the City of Tukwila to support installation of a new stormwater system, grading to promote drainage, and paving to support use of the area for warehousing and storage of automobiles within the West Parcel. This assessment of fill depth is being made to evaluate the potential for exposing or excavating native materials during the work planned for the West Parcel. Of the planned activities, only installation of the new stormwater management system will require excavation. Background The former Rhone- Poulenc site is located adjacent to the Duwamish Waterway, just to the north of "Slip 6 ". Slip 6 is a former channel of the Duwamish River. The Duwamish River was dredged and straightened from 1913 through 1920; the portion of the river adjacent to the former Rhone- Poulenc site is now referred to as the Duwamish Waterway. Based on available documentation (CH2M HILL, 1995; Landau, 1991), much of the property, especially the western portion, consisted of tidal flats. It is likely that much of the West Parcel was submerged at high tide prior to filling of the area. Although no specific records are available, the majority of the property was probably filled at the time that the waterway was dredged; the typical practice was to slurry the hydraulically dredged material onto the land surface using a system of pipes. It is expected that the site was filled some time between 1913 and 1920, when the waterway was constructed. Since the dredge material was derived from river sediments, the fill materials (sands and silts) resemble the materials native to the site prior to dredging. Approximately two acres of tide flats remain along the western side of the property. J:\8769.000 RCI R- P1086\Fill Depth Memo_FINAL.doc One Union Square. 600 University Street.

NAME: Former Rhone- Poulenc Site Tukwila, Washington www.geomatrix.com RECEIVED 'APR 0 7 2006 COMMUNI I Y DEVELOPMENT Geomatrix Memorandum April 6, 2006 Page 2 of 4 • Depth of Man - Placed Fill Site investigation reports and lithologic logs for wells and soil borings that were completed onsite were reviewed to assess the present depth of fill at the former Rhone- Poulenc site. The RCRA Facility Investigation Report prepared by CH2M HILL reported that "... hydraulic fill consisting of dredged sand and silt is present in the upper 5 to 15 feet of the subsurface." The CH2M HILL report refers to the entire site and is not limited to the West Parcel. It is likely that the western portion of the site, near the waterfront, has a greater depth of fill than the eastern portion which borders East Marginal Way South. The boring logs prepared for the site characterize observations using standard soil classifications, but do not distinguish between fill and native materials. However, review of the boring logs shows a consistent layer of silt at a depth of 5 to 15 feet below the present surface grade over much of the site. This silt layer is distinguished from similar materials by its reported density and the presence of organic material such as plant roots. The depth of the fill materials reported by CH2M HILL and the description of the site as a "tide flat" prior to development suggest that the layer of silt present at the site may represent the historic surface of the original tide flat. The elevation of the silt layer in soil borings is approximately the same as the present elevation of the tide flats on the west side of the property. Other indicators, which can be used to distinguish between fill and native materials, are the presence of recent man -made objects or debris noted in the boring logs. If such material is noted in the log, the material would be considered to be fill material. The boring logs for the southeastern corner of the West Parcel, nearest the planned location for installation of the Stormceptor®, indicate that the depth of fill ranges from about 6 to 12 feet below existing grade. The `ordinary high water mark" shown on the recent survey map of the site is shown at approximately 5 feet in elevation, which is approximately 12 feet below present grade. It is likely that the elevation of the former tide flats was probably no greater than 1 to 2 feet above the ordinary high water mark, or at an approximate elevation of 6 to 7 feet above mean sea level. The projected elevation of the former tide flat suggests that there is approximately 10 to 11 feet of fill in the southeast comer of the West Parcel. Available information from previous site investigation reports and from more recent boring logs indicate that the depth of man - placed fill within the West Parcel is generally 5 to 12 feet below the current site surface. In the southeast corner of the West Parcel, the expected depth of fill is 10 to 11 feet, but localized areas may be only about 6 feet in depth. In most locations, the presence of native soil can be identified by the presence of a silt layer. The native soils were exposed as recently as 85 to 90 years ago. .i:\8769.000 RCI R -P1086 \Fill Depth Memo_FINAL.doc Geomatrix Memorandum April 6, 2006 Page 3 of 4 Depth of Excavation During redevelopment of the West Parcel, limited excavation will be conducted to install underground storm sewers and an underground stormwater treatment unit. Final elevations will be attained by importing clean fill. Grading of soils presently onsite will be limited to elevated areas presently beneath building floors and other localized mounds. Grading has been designed to limit disturbance of surficial materials which may have been contaminated by historic industrial activities at the site. All grading will disturb only fill material. Therefore, only the limited excavation to install the stormwater management system has potential to disturb native soils. Installation of the stormwater system will require excavation of trenches for sewer and catch basin installation and a larger excavation to install a Stormceptor water quality unit. Trench excavations will be distributed over much of the West Parcel. Most of the trenching will be limited to depths from 4 to 6 feet below existing grade. The deepest trenching will be for the collector stormwater lines running north -south in the eastern portion of the West Parcel. The collector lines leading to the Stormceptor unit will be excavated to a maximum depth of about 7 feet below existing grade. As noted above, the approximate depth of fill is 5 to 7 feet in the area where the collector storm sewer will be located. The deepest excavation will be for installation of the Stormceptor water quality unit and for discharge piping running to the existing 36 -inch storm sewer entering the eastern end of Slip 6. The projected excavation depth is approximately 11 feet below existing grade. The location of the Stormceptor is near the southeast corner of the West Parcel, just north of the eastern end of Slip 6. It is expected that all soil above and adjacent to the existing 36 -inch sewer line consist entirely of man- placed fill. Conclusion Based on available site information and expected excavation depth, it is projected that trenching and excavation for placement of sewer lines and catch basins to the west and east of the collector north -south sewer will be placed entirely within man- placed fill. Installation of the north -south collector sewer may require excavation into native soils; it is estimated that the maximum depth of excavation into native soil would be approximately 1 foot. The deep excavation in the southeast corner of the West Parcel for installation of the Stormceptor water quality unit is expected to extend no more than 1 foot into the native soils underlying man- placed fill, but the excavation could extend up to 5 feet into native soil if a localized high point is encountered. Available information for the site indicates that filling of the property occurred over about a 7 year period and was likely completed by 1920.

January 4, 2006, response to technical comments letter 9. SEPA staff report Introduction The applicant, Davis Properties, has applied for shoreline variance approval to allow parking waterward of a proposed building, rather than beneath or upland of the building as required by Section 26.16.030.E of the King County shoreline regulations (which apply to this site). The Department of Community Development recommends approval of the variance. The public hearing on the application was held on May 9, 2006, in Conference Room 2, 6300 Southcenter Boulevard. Represented at the hearing were: the Department, by Carol Lumb, Senior Planner; and the applicant, by Ivana Halvorsen and Brendon Madden, Barghausen Consulting Engineers, and Jeffrey E. Davis, DPI. No member of the public appeared. After due consideration of the evidence presented at the public hearing, the following shall constitute the findings of fact, conclusions and decision of the Hearing Examiner on this application. Findings of Fact 1. The subject site is addressed as 9229 East Marginal Way South, and is accessed from East Marginal Way. The entire site is approximately 19.5 acres and is adjacent to the Duwamish River which is west of the site. In addition, the Port of Seattle's Slip No. 6 lies along the southern border of the western portion of the site. The site is irregularly - shaped, with the eastern half being much narrower than the western half of the property. The site is developed with abandoned structures and other impervious surface areas. 2. The property is zoned Manufacturing Industrial Center/Heavy (MIC/H). The site is designated as Urban Environment under King County's Shoreline Master Program. 3. North of the site is an auto salvage yard, which has surface parking within the shoreline environment. Exhibit 5. That parking was not subject to either shoreline substantial development or shoreline variance review, as it was determined not to constitute development under the state Shoreline Management Act. South of the site Hearing Examiner Decision L05 -051 Shoreline Variance Page 3 of 6 across Slip No. 6 is the Boeing Development Center, and the Boeing Museum of Flight. To the east across East Marginal Way is the King County Airport. 4. The property has been contaminated because of previous chemical manufacturing activities at the site. Corrective actions for historic releases at the site are underway, subject to an EPA Order on Consent under the Resource Conservation and Recovery Act. Remediation and testing activities at the site have been ongoing for several years. Most of the remediation efforts and testing are directed at the western portion of the site. It is possible that no cleanup, or removal of only small areas of contamination, will be required for the eastern part of the site. The proposed building and parking stalls would be located on the eastern portion of the site, as shown in the plans at Exhibit 6. Proposal 5. The proposal is for variance relief to allow 27 surface parking stalls to be located within the shoreline area, along with landscaping as proposed in Exhibit 6. (The application initially included a request for a variance to exceed the height limit, but the applicant withdrew that request prior to hearing.) 6. The applicant proposes to construct an 84,000 square foot warehouse /office building on the site (identified as "Building A" on Exhibit 6), with a loading area located to the north, and approximately 189 parking stalls along the other three sides of the building. The applicant intends that the building will be a multi -tenant facility, requiring separate tenant access points and parking along the southern side of the building, away from the warehouse and loading areas along the north side of the building. The 27 parking stalls that are the subject of this application are located near the south and east sides of the proposed building, within the 200 -foot shoreline area. 7. The site was annexed to the City after the adoption of the City's Shoreline Master Program, and is therefore subject to the King County Shoreline regulations. KCC 25.16.030.E requires that parking be located underneath or upland of the building served by the parking. 8. The King County shoreline regulations include the following requirements for shoreline variances at KCC 25.32.040: A. The director is authorized to grant a variance from the performance standards of this master program only under the conditions enumerated WAC 173 -14 -150 (Review Criteria for Variances). B. A variance from county zoning code requirements shall not be construed to mean a variance from shoreline master program use regulations and vice versa. Hearing Examiner Decision L05 -051 Shoreline Variance Page 4 of 6 C. Shoreline variances may not be used to permit a use that is specifically prohibited in an environment designation. D. The burden of proving that a proposed variance meets these conditions shall be on the applicant; absence of such proof shall be grounds for denial of the application. E. The fee which shall accompany an application for a shoreline variance shall be as adopted by ordinance. 9. The Department has reviewed the warehouse /office project and the associated parking, and has issued a Determination of Nonsignificance pursuant to SEPA on that proposal. The overall project will also be reviewed by the Department as part of the application for a shoreline substantial development permit, administrative design review approval, and short plat approval. 10. The Department recommends that the application for the variance be approved, along with the landscaping that is shown on the plans. Conclusions 1. The Hearing Examiner has jurisdiction over this application pursuant to TMC 18.104.010.D. The application is subject to the shoreline variance requirement found in KCC 25.32.040, which states that a variance is authorized under the conditions enumerated in WAC 173 -14 -170. Each of the criteria of WAC 173 -14 -170 is considered below. 2. The denial of the permit would thwart the re -use and development of this property in a manner that would be consistent with the industrial uses surrounding the area. The relevant circumstances in this case include the location of the Port's Slip to the south, which "creates" a shoreline environment in addition to that associated with the main Duwamish Waterway to the west; the past contamination of the site, which affects the configuration of development at the site; and the surrounding uses, which favor a design that places the loading areas for this site to the north and the office areas to the south. The public interest would suffer no substantial detrimental effect from the placement of the parking stalls with landscaping in the shoreline area. 3. The strict application of the regulation requiring underground or landward parking would significantly interfere with a reasonable use of the property. The 27 stalls could not be placed outside of the shoreline area on the site without reducing the size of the building, and/or moving the truck loading areas to the south and the surface parking to the north. However, the information in the record indicates that this orientation would not be consistent with the proposed use of the building or compatible with the adjacent uses that face the site from the north and site. Elimination of the parking stalls would not • Hearing Examiner Decision L05 -051 Shoreline Variance Page 5 of 6 bring the proposal below what is required by the Code for this use, but the applicant's information indicates that the 27 stalls are needed to meet the parking demand anticipated for the office uses at the site. 4. The property is irregular in shape and is constrained by the presence of the man- made slip on the south side, which extends the shoreline jurisdiction to the southern areas of the site. The contamination of the western portion of the site because of past practices also means that the use of the site is constrained for purposes of relocating parking or other uses to the western portion of the site. 5. The proposed design of the project is compatible with other authorized uses in the area. The parking area would be part of a proposed warehouse /office development that is consistent with other uses in the area; the entrances to the proposed office spaces would be on the south side, facing the Boeing properties and Flight Museum to the south, while the loading areas would face the auto salvage use to the north. The parking spaces would be landscaped, with an average depth of 35 feet of landscaping. 6. The variance would not grant a special privilege not already enjoyed by other properties in the area. Surface parking for the Boeing facility to the south is located within 200 feet of the shoreline environment, as is the surface parking to the north on the auto salvage yard property. 7. The information in the record shows that the variance for 27 stalls in the shoreline area is the minimum necessary to afford relief. As noted above, to reduce the number of stalls in the shoreline area would require re- orientation of the building and uses at the site, which is not feasible, and elimination of the stalls would fall short of the anticipated parking demand for the site and its uses. 8. The public interest would suffer no substantial detrimental effect. No detrimental effects have been shown to result from the location of the 27 parking stalls in the shoreline area. The warehouse /office project has also been subject to a number of reviews associated with the other approvals that are required for that larger project. Impacts that may result from the project as a whole, including the parking stalls, have been addressed through SEPA review and through the shoreline substantial development permit process, as well as other City, state and federal requirements. 9. No work would occur waterward of the Ordinary High Water Mark. 10. The information in the record shows that cumulative impacts are not a factor in this request. The adjacent uses to the north and south already have parking areas which are within the shoreline environment. The 27 additional parking stalls proposed to be in the shoreline area on this site would be landscaped, and would be consistent with other uses in the surrounding area. • • • Hearing Examiner Decision L05 -051 Shoreline Variance Page 6 of 6 11. The conditions of WAC 173 -14 -150 are therefore present, as required under KCC 25.32.040.A. The remaining provisions of KCC 25.32.040 are also met. No variance from the use regulations of the master program are being sought, and the uses are permitted in the Urban Environment. Based on the information in the record, the applicant has sustained its burden of showing that the proposed variance criteria have been met. The application should therefore be approved. The application for a shoreline variance to permit 27 parking stalls within the shoreline environment along with the landscaping shown in the drawings in Exhibit 6, is hereby approved.

Reply To Attn of: AWT -121 VIA CERTIFIED MAIL - RETURN RECEIPT REQUESTED Re: Approval with Modification of Westem Parcel Redevelopment Work Plan Administrative Order on Consent for Corrective Action ( "Order") Under the Resource Conservation and Recovery Act ( "RCRA ") Docket No. 1091- 11- 20- 3008(h) Rhone - Poulenc Inc. Marginal Way Facility WAD 00928 2302 RECEIVED 'APR 0 7 2006' COMMUNITY DEVELOPMENT The U.S. Environmental Protection Agency, Region 10 ( "EPA ") has completed its review of the revised Western Parcel Redevelopment Work Plan for the former Rhone - Poulenc facility, dated March 13, 2006. This revision was prepared in response to EPA's comments dated February 9, 2006_ Pursuant to Paragraph 7.1 of the Order, the revised Westem Parcel Redevelopment Work Plan is hereby conditionally approved with modification. EPA's approval is conditioned on Respondents modifying the final revised Westem Parcel Redevelopment Work Plan as directed by EPA in this letter. Page 2 of the revised Westem Parcel Redevelopment Work Plan is hereby modified as follows: Delete the seventh sentence of Section 1.1, which states that Container Propertes has primary responsibility for implementing the provisions of the Order. All Respondents are equally responsible for implementation of work plans and overall compliance with the Order. Please submit a revised page 2 of the Westem Parcel Redevelopment Work Plan, including the revision specified above, within thirty (30) days of receipt of this approval with modification as set forth by Paragraph 7.2 of the Order. The effort and care that went into preparation of the final Westem Parcel Redevelopment Work Plan is evident and is appreciated. The high quality of the final document has allowed EPA to approve the revised work plan quickly. Printed on Recycled Paper • • Respondents are cautioned that the work set forth in the Redevelopment Work Plan is scheduled to occur prior to the approval of a Corrective Measures Study and selection by EPA of a final corrective measure. The process of selecting a corrective measure is subject to public review and comment, Tribal consultations, and consultations with other federal agencies under the Endangered Species Act. This work could be in conflict with work that EPA determines is required to be conducted under the Order, and is, thus, being undertaken at the Respondents' risk. For example, aspects of this redevelopment work could be required to be redone or disturbed to the extent that they are determined by EPA to be inconsistent with work required under the Order. Nothing in the Redevelopment Work Plan, or EPA's communication relating to it, alters or affects Respondents' existing responsibilities and obligations under the Order. You may contact me at (206) 553 -8506, or your legal counsel may contact Jennifer MacDonald at (206) 553 -8311, if you have any questions regarding this letter. cc: G. St. Amant, Muckleshoot Tribe B.

I reviewed the "Interim Measures Construction Work Plan (URS 2002) in our files to get a better understanding of the contamination issues, the location of the groundwater recovery wells, and the pre- treatment system (none of which is shown on the plans). I also spoke with the EPA project manager, Christy Brown to get an update on what is going on at the site and what future clean-up actions (if any) were contemplated and to understand who will have responsibility for ongoing operation, maintenance and monitoring of the groundwater treatment program. Per my conversation with Christy Brown on September 19, the current remediation work (groundwater barrier, recovery wells, pretreatment system and discharge to sanitary sewer) is only an interim remediation. Additional site clean -up will likely be needed in the future and may involve remediation along the river bank and along Slip 6, including possible sediment removal. The interim remediation system was only installed and put into operation lastyear, despite EPA's order (to the responsible party - Rhone Poulenc) in March of 2000 to install and operate the system. Christy indicated that there is still some question about the effectiveness of the current system, particularly related to the location of the recovery wells. Apparently EPA will be starting some groundwater monitoring soon to evaluate the effectiveness.of the system. Per EPA, the proposed Operation, Monitoring, Inspection and Maintenance Plan that is mentioned in the SEPA Checklist only applies to operation of the interim groundwater recovery and treatment system and not to any other activities at the site (such as grading). A separate health and safety plan will be needed for site grading/filling activities. Christy said that at least Level D Personal Protective Equipment will be required for site workers. Level D generally means the use of steel toed boots, hard hats, gloves, and protective eyewear. Regarding the proposal to subdivide the property, EPA said that there are minimal contamination issues for the eastern half of the property. Some soil contamination (oil and grease and some metals that exceed MTCA industrial and residential levels) is present and will need to be removed, as EPA is refusing to allow deed restrictions as a way to avoid dealing with the contamination. There has been no groundwater contamination detected on that part of the property. The main issues of concern are on the western part of the property. In addition to the known contamination, there is concern over what might be in the underground piping and tanks. No information was provided to the current owner about these issues when the property was Plans: • • transferred. EPA has encouraged the applicant to do some investigation of the pipes and tanks and Christy has indicated that the applicant may dig some test pits to evaluate. EPA has no problem with the applicant's proposal to fill the western portion of the site with concrete from Sound Transit and then pave it for leasing to an auto auction, but the applicant does so at the risk of having to possibly remove it for later clean -up actions. EPA also has no problem with moving the pretreatment system or demolishing the building in which the treatment plant is located. One of their concerns is the same as one of mine — how the top of the barrier wall and the monitoring and extraction wells will be protected during and after grading and paving. Below are my recommendations regarding the proposed land use actions. 1. I think the City should ask for a copy of EPA's written approval of the actions to be taken on- site. 2. The plans should show the three groundwater recovery wells in addition to the monitoring wells. 3. The plans should indicate where the existing groundwater pretreatment facility is located, as well as the proposed new location. In addition, piping details should be provided on the plans — both existing and proposed. 4. The plans should indicate current location of the on -site King County lift station and indicate whether it will also be relocated. 5. It is unclear from review of the documents provided how the groundwater recovery wells, the groundwater pretreatment system piping, monitoring wells, and the upper surface of the slurry walls will be protected during grading and construction. SEPA Checklist: 6. Section B.1., item f. The response to the question of whether erosion could occur as a result of clearing, construction, or use, not make any sense. The slurry wall does nothing to protect sediment from leaving the site, as it is below ground and was constructed to intercept groundwater, not surface water. 7. Section B.7., items 1 and 2. The City should be provided with a copy of the EPA - approved Operation, Monitoring, Inspection, and Maintenance Plan referenced in the SEPA Checklist. 8. The applicant or applicant's contractor should prepare a very specific and detailed health and safety plan, including emergency measures and daily decontamination procedures. We should probably ask for a copy of the plan for our files. The contractor's site workers will also need to have been trained in health and safety procedures, since this is a Superfund site. We might want to ask for a copy of the worker's training certificates, although I don't think it is an absolute necessity.

While this project will not be subject to a public hearing before Tukwila's Board of Architectural Review, the Administrative Design Review process still reviews the same design - related materials. Before Notice of Application can be issued or any additional review of the project can occur, the items missing and identified on the attached Checklist must be submitted. Pursuant to TMC 18.104.130 if the materials requested above are not submitted within 90 days of the date of this letter, the Department may cancel the application due to inactivity. If you have any questions, please call me at 206 - 431 -3661. I will be out of the office September 15 -19, returning on Tuesday, September 20, 2005. ,5 Southcenter Boulevard_ Suite #100 • Tukwila.

Box 1043 Kent, WA 98035 -1043 Department of Community Development Steve Lancaster, Director RE: Property at 9229 East Marginal Way South Dear Mr. Davis: A public hearing has been scheduled for May 9, 2006 at 9:00 a.m. to consider the shoreline variance request. Once a decision is issued by the Hearing Examiner, if the request is approved, then the City can issue the shoreline substantial development permit. That permit is valid for two years from the effective date of the permit (the date a complete submittal is filed with the Department of Ecology). A one -time extension of up to one year can be granted based on reasonable factors. Once construction begins, you have five years to complete the development from the effective date of the shoreline permit. Again, a one -time extension of up to one year can be granted based on reasonable factors. Requests for permit extensions must be submitted prior to the expiration of the permit. Since you are still conducting clean up activities on the eastern portion of the site, I wanted to make sure you were aware of the time limits on the permit once it is accepted by Ecology. If you will be substantially delayed in constructing the building, you may want to request that the City delay action on the shoreline substantial development permit. Please let me know when you anticipate beginning construction of the building on the site. If you have any questions, please let me know. I can be reached at 206 - 431 -3661.

Yes, they have asked us to separate out the East parcel from the rest of the site. The contamination patterns are very different between the two parcels, and they seem to have different redevelopment plans for the two parcels. That being said, both parcels will remain subject to the Order unless they can achieve a "corrective action complete without controls" on the East Parcel -- longhand for "cleaned up to residential standards ". They aren't there yet -- more field work is certainly in order, based on the data we have so far. We have been working with them to substantially revise the East Parcel Cleanup Work Plan (the one they just sent you) - so you need to know that that particular document (November 2005) will not be approved as written. I haven't seen a revised work plan yet. My understanding is that they aren't planning to start construction on the east parcel until they've gotten some sort of buy -off from EPA and have been able to determine whether they can achieve a walk -away cleanup on that parcel or will be left with some residual contaminants (at the "industrial" levels found in MTCA).

The site is regulated under the Resource Conservation and Recovery Act (RCRA). The site is proposed to be short platted into two parcels, with the building construction to occur on the eastern-most lot. Approval to demolish the existing structures on the site was the subject of a previous SEPA approval, E04 -021.

The Integrated Plan and Final EIS were completed in March, 1998. Both the Duwamish Corridor Redevelopment EIS and the Tukwila Manufacturing/Industrial Center Integrated GMA Implementation Plan and Environmental Impact Statement analyze the environmental impacts of a range of development and redevelopment alternatives on properties in the MIC corridor. The proposed project meets the criteria for Planned Action SEPA: • the proposed uses are permitted in the MIC/H district; • impacts from the project will be mitigated by the time the project is complete; • the project is consistent with the Tukwila Comprehensive Plan, specifically Goal 11.1, supporting development of new industrial activities in the MIC and Policy 1.1.2, assisting landowners in remediating site problems caused by contaminated soil. • the project is not an essential public facility, related to light rail or commuter rail, the 16 Avenue South Bridge or include development waterward of the ordinary high water mark. The site has been under industrial use since the 1930s. In the 1930's a plant to produce glue for use in plywood manufacturing was constructed on this site. In 1946, the site was purchased by Monsanto Chemical Co., which continued the manufacture of glue as well as paints, resins, and storage of wood preservatives. Monsanto began vanillin production in 1952 which continued through the sale of the property to Rhone- Poulenc in 1986. The vanillin manufacturing facility closed in 1991. Historic releases of hazardous substances occurred at the site. Released materials include caustic soda, toluene, mineral oil, PCBs and copper. Corrective action for the historic releases is being addressed under a Resource Conservation and Recovery Act (RCRA) Administrative Order on Consent issued by the U.S. Environmental Protection Agency, Region 10 (Docket .# 1091- 11- 20- 3- 8(h)).

A small amount of grading occurred when the groundwater pretreatment system associated with the hydraulic control interim measure was relocated earlier this year. Additional grading will occur when with the demolition of existing pavement and buildings for repaving and the new warehouse /office building. There will also be trenching for the installation of storm water lines on the western portion of the site and excavation for the installation of the stormceptor system. Some erosion could occur as a result of the construction activities when the existing paving and buildings are removed. There may also be some excavation of contaminated soils on the eastern portion of the site. The Draft East Parcel Cleanup Work Plan, prepared in November, 2005 by Geomatrix, identifies several areas that are slightly above clean -up standards. The applicant is working with EPA to identify the appropriate course of action for this portion of the site. A statistical sampling of the whole eastern parcel will be prepared and reviewed by EPA; it is possible that no clean up will be required of this portion or that small "hot spots" will be excavated (telephone conversation 4/14/06 with Gary Dupuy, East Parcel Cleanup Project Coordinator, Geomatrix). Temporary erosion and sedimentation control (TESC) measures will be implemented prior to construction, including catch basin protection, silt control fences and other best management practices. Air During demolition, vehicle and construction equipment emissions and dust will be released. Dust and vehicular emission from construction is expected. After construction, automobile and truck emissions typical of heavy industrial uses can be expected at the site. Water The Duwamish River borders the site on the west and south. The Checklist states that the site is a registered Superfund site, however this is not correct. The site has been contaminated by the previous chemical manufacturing activities and is subject to ongoing governmental oversight and environmental monitoring including ongoing monitoring and maintenance of the groundwater extraction and treatment system by the U.S. Environmental Protection Agency under the Resource Conservation and Recovery Act (RCRA). Remediation activities and substantial environmental testing has occurred since the former Rhone Poulenc operations ceased in 1991. Remediation activities are ongoing pursuant to the 2002 Interim Measures Construction Work Plan, prepared by Geomatrix Consultants Inc. dated June 3, 2003. A number of construction activities will take place within the 200 -foot shoreline of the Duwamish — removal of existing buildings and asphalt, grading, removal of existing railroad track, repaving the site and construction of a 84,000 sq. ft. warehouse /office building with associated parking.

Stormwater from the site will be collected and treated in two water quality stormceptors and then discharged via a 36 -inch King County stormwater pipe to the Duwamish Waterway. The building permit application will be required to include a design approval letter from the stormwater treatment manufacturer and a storm drainage maintenance schedule that clearly identifies who, what, when and how maintenance will be performed. This will be recorded on the title of the property. Subsurface low permeability barrier walls surrounding the western portion of the site were installed in accordance with the EPA approved Interim Control Measure The barrier walls were installed to contain the contaminated portion of the site to the maximum extent practicable. A system of groundwater extraction wells and a pre- treatment system were installed to pump groundwater from the inside of the contained area, thereby creating an inward groundwater gradient. The pre- treated groundwater is discharged to a publicly owned treatment works, owned and operated by King County and permitted under the Clean Water Act. The groundwater pre- treatment system is an integral part of the Hydraulic Control Interim Measure; this system has been relocated as part of the redevelopment of the site. Groundwater withdrawal will be equal to the amounts currently withdrawn. Numerous wells were installed at the site during site characterization and as part of the interim remedial measures that have been implemented. Some of the wells are being used for monitoring or remediation purposes, but a number are no longer used. Wells represent a potential flow path for surface spills to enter groundwater. Wells can become damaged from surface activities, particularly uses that involve heavy equipment such as when the western portion of the site is graded and the elevation increased and when the storm water system is installed. The applicant is planning to abandon all wells that are not required for long -term monitoring prior to site grading and filling. Geomatrix Consultants Inc. has prepared the Western Parcel Redevelopment Work Plan, dated November, 2005 to guide the well abandonment and protection of wells to be retained. The wells will be abandoned by a licensed driller in accordance with the Department of Ecology well abandonment procedures. Geomatrix Consultants has also prepared the Draft East Parcel Cleanup Work Plan, for the eastern portion of the site that will be developed with the proposed warehouse /office building. The casing of the retained wells will be extended up to the new grade of the site. The redeveloped site will cap the existing ground surface, which is expected to help reduce or eliminate storm water penetration and seepage into the contaminated soils. Project generated waste materials are unlikely to enter the groundwater as storm water from the repaved parking areas and buildings will be collected in a closed catch basin and pipe system that will be directed to an underground water quality vault prior to release into the Duwamish River. Plants As noted above, the site is almost 100% impervious surface with some landscaping features that remain around the existing abandoned buildings. These plantings will be removed when the CL Page 4 of 7 04/18/2006 8:58:00 AM q:\Davis Properties\SEPA Staff Rpt.doc Planned Action SEPA Re E05 -011 Davis Development — Form Rhone/Poulenc Site April 14, 2006 Energy/Natural Resources buildings are demolished. Landscaping will be planted as part of an approved design for the proposed warehouse /office building and parking areas and will also be provided on the west and south sides of the site as part of an approved Shoreline Substantial Development permit to provide screening. Animals • The site is adjacent to the Duwamish Waterway, which is a migratory route for Chinook, Chum, Coho, Pink, Steelhead, and Cuthroat Salmon and Bull Trout. The site is also on the route of the Pacific Flyway, a migratory bird route. The site will use electricity for parking lot and building lighting and electricity or possibly natural gas for building heating and operations. No lighting is proposed for the western portion of the site where the auto storage is proposed. The proposed warehouse /office is required to meet the Washington State Energy Code. Environmental Health As the property contains contaminated soils, exposure to hazardous materials is a risk during construction. An Operation, Monitoring, Inspection and Maintenance Plan has been prepared which will be approved by EPA prior to redevelopment activities. The Plan specifies procedures for protection of contractor health and safety during site grading. The site redevelopment as proposed will effectively cap the surface to eliminate or reduce storm water seepage that would contribute to off -site impacts from contaminants. A number of the monitoring wells that are no longer being used will be capped, which will also reduce the possibility of additional environmental health hazards from the site. The site is located in an industrial area with the noises associated with industrial activity. Land/Shoreline Uses The site was formerly used to manufacture vanillin. The existing structures will be demolished prior to the redevelopment of the property. The site is bordered on the north by an auto auction storage yard; to the south a Port of Seattle Slip and Boeing Development Center; on the east by the King County Airport and on the west by the Duwamish Waterway. The property is within the Manufacturing Industrial Center/Heavy zoning district. Portions of the site are within 200 feet of the Duwamish Waterway, a shoreline of the state. The site is governed by the King County Shoreline Master Program (SMP), as this area was annexed from unincorporated King County and is not covered by the City's Shoreline Master Program. The County SMP designates the site as Urban Environment. King County Code Title 25 contains the regulations for development in the industrial shoreline area. The applicant has applied for a shoreline substantial development permit and a shoreline variance for placing parking waterward of the proposed building and for an increase in building height in the shoreline environment.

Aesthetics The applicant has requested a shoreline variance to permit the warehouse /office building to be higher than 35 feet within the 200 foot shoreline environment. The building will not block residential views of the shoreline. Light/Glare No significant glare will be generated by the proposed development as lighting will be limited to fixtures mounted on the warehouse/office building. No lighting is proposed in the parking lot supporting the proposed building or the parking area on the western portion of the site to be leased by the adjacent property owner (an auto insurance auction facility). Providing adequate lighting for safety purposes will be addressed through the Administrative Design Review process. Building materials to be used are non - reflective. Recreation Not applicable. Historic /Cultural Preservation One comment was received from the Muckleshoot Indian Tribe Cultural Resources Program stating that this site is in an area the Tribe has flagged as high potential for archaeological discovery (see Attachment A). The applicant has provided a response prepared by Geomatrix discussing the depth of fill on the western portion of this site (see Attachment B). Generally the site was filled at the time the Duwamish Waterway was dredged and created. The report prepared by Geomatrix states that dredged sand and silt is present in the upper 5 to 15 feet of the subsurface. A limited amount of excavation will be conducted to install underground storm sewers and an underground stormwater treatment unit. Installation of the stormwater system will require trenching at depths of 4 to 6 feet, within the depth of fill noted by earlier studies of the site. The deepest trenching will be for the collector lines running north -south in the eastern portion of the western parcel, which will be excavated to a maximum depth of about 7 feet below existing grade. The depth of fill in that area is 5 to 7 feet. The deepest excavation will be for installation of the Stormceptor water quality unit and the discharge piping running to the existing 36 -inch storm sewer entering the eastern end of Slip 6. This proposed excavation depth will be approximately 11 feet below existing grade. The Stormceptor will be installed at the southeastern corner of the western parcel. The report anticipates that the soil above and adjacent to the existing 36 -inch sewer line consists of man - place fill.

The 9229 East Marginal Way South property is an area the Tribe has flagged as high potential for archaeological discovery. The project area location is one that the Tribe considers to have a high probability for archaeological resources, because there are previously identified archaeological sites and a traditional cultural place nearby. Although the proposed project area appears to be previously disturbed, I cannot tell from the information provided whether the proposed construction could intersect native soils on -site. If that is a possibility, then we request that an archaeological study be conducted of the project area to determine the best means of identifying and protecting archaeological resources that may be uncovered during construction. , If the applicant believes that construction would take place entirely within fill, we request supporting documentation, such as a comparison of construction plans and soil profile information. Information regarding previous surveys and recorded archaeological sites is available from the Office of Archaeology and Historic Preservation, in Olympia. The Cultural Resources Program does not represent the Wildlife Program and the Fisheries Program which are separate departments under the Muckleshoot Indian Tribe. Please contact these departments separately for their input on this project. We appreciate the effort to coordinate with the Muckleshoot Tribe prior to site preparation. The destructive nature of construction excavation can often destroy a site and cause delays and unnecessary expense for the contractor. If you have any questions, please contact me at 253- 876 -3272.

NO.: 8769.005 John Long CC: Gary Dupuy PROJ. NAME: Former Rhone- Poulenc Site Tukwila, Washington SUBJECT: Depth of Fill at Former Rhone - Poulenc Site This memorandum discusses the depth of fill materials in the western portion of the former Rhone- Poulenc facility located at 9229 E. Marginal Way South, in Tukwila, Washington. The portion of the site proposed for installation of a new stormwater system is referenced in this memorandum as the West Parcel. Plans and applications have been filed with the City of Tukwila to support installation of a new stormwater system, grading to promote drainage, and paving to support use of the area for warehousing and storage of automobiles within the West Parcel. This assessment of fill depth is being made to evaluate the potential for exposing or excavating native materials during the work planned for the West Parcel. Of the planned activities, only installation of the new stormwater management system will require excavation. Background The former Rhone- Poulenc site is located adjacent to the Duwamish Waterway, just to the north of "Slip 6 ". Slip 6 is a former channel of the Duwamish River. The Duwamish River was dredged and straightened from 1913 through 1920; the portion of the river adjacent to the former Rhone- Poulenc site is now referred to as the Duwamish Waterway. Based on available documentation (CH2M HILL, 1995; Landau, 1991), much of the property, especially the western portion, consisted of tidal flats. It is likely that much of the West Parcel was submerged at high tide prior to filling of the area. Although no specific records are available, the majority of the property was probably filled at the time that the waterway was dredged; the typical practice was to slurry the hydraulically dredged material onto the land surface using a system of pipes. It is expected that the site was filled some time between 1913 and 1920, when the waterway was constructed. Since the dredge material was derived from river sediments, the fill materials (sands and silts) resemble the materials native to the site prior to dredging. Approximately two acres of tide flats remain along the western side of the property. J: \8769.000 RCI R -P \086 \Fill Depth Memo_FINAL.doc One Union Square. 600 University Street. Suite 1020 Seattle.

The RCRA Facility Investigation Report prepared by CH2M HILL reported that "... hydraulic fill consisting of dredged sand and silt is present in the upper 5 to 15 feet of the subsurface." The CH2M HILL report refers to the entire site and is not limited to the West Parcel. It is likely that the western portion of the site, near the waterfront, has a greater depth of fill than the eastern portion which borders East Marginal Way South. The boring logs prepared for the site characterize observations using standard soil classifications, but do not distinguish between fill and native materials. However, review of the boring logs shows a consistent layer of silt at a depth of 5 to 15 feet below the present surface grade over much of the site. This silt layer is distinguished from similar materials by its reported density and the presence of organic material such as plant roots. The depth of the fill materials reported by CH2M HILL and the description of the site as a "tide flat" prior to development suggest that the layer of silt present at the site may represent the historic surface of the original tide flat. The elevation of the silt layer in soil borings is approximately the same as the present elevation of the tide flats on the west side of the property. Other indicators, which can be used to distinguish between fill and native materials, are the presence of recent man -made objects or debris noted in the boring logs. If such material is noted in the log, the material would be considered to be fill material. The boring logs for the southeastern comer of the West Parcel, nearest the planned location for installation of the Stormceptor®, indicate that the depth of fill ranges from about 6 to 12 feet below existing grade. The "ordinary high water mark" shown on the recent survey map of the site is shown at approximately 5 feet in elevation, which is approximately 12 feet below present grade. It is likely that the elevation of the former tide flats was probably no greater than 1 to 2 feet above the ordinary high water mark, or at an approximate elevation of 6 to 7 feet above mean sea level. The projected elevation of the former tide flat suggests that there is approximately 10 to 11 feet of fill in the southeast corner of the West Parcel. Available information from previous site investigation reports and from more recent boring logs indicate that the depth of man- placed fill within the West Parcel is generally 5 to 12 feet below the current site surface. In the southeast corner of the West Parcel, the expected depth of fill is 10 to 11 feet, but localized areas may be only about 6 feet in depth. In most locations, the presence of native soil can be identified by the presence of a silt layer. The native soils were exposed as recently as 85 to 90 years ago.

Final elevations will be attained by importing clean fill. Grading of soils presently onsite will be limited to elevated areas presently beneath building floors and other localized mounds. Grading has been designed to limit disturbance of surficial materials which may have been contaminated by historic industrial activities at the site. All grading will disturb only fill material. Therefore, only the limited excavation to install the stormwater management system has potential to disturb native soils. Installation of the stormwater system will require excavation of trenches for sewer and catch basin installation and a larger excavation to install a Stormceptor water quality unit. Trench excavations will be distributed over much of the West Parcel. Most of the trenching will be limited to depths from 4 to 6 feet below existing grade. The deepest trenching will be for the collector stormwater lines running north -south in the eastern portion of the West Parcel. The collector lines leading to the Stormceptor unit will be excavated to a maximum depth of about 7 feet below existing grade. As noted above, the approximate depth of fill is 5 to 7 feet in the area where the collector storm sewer will be located. The deepest excavation will be for installation of the Stormceptor water quality unit and for discharge piping running to the existing 36 -inch storm sewer entering the eastern end of Slip 6. The projected excavation depth is approximately 11 feet below existing grade. The location of the Stormceptor is near the southeast corner of the West Parcel, just north of the eastern end of Slip 6. It is expected that all soil above and adjacent to the existing 36 -inch sewer line consist entirely of man- placed fill. Conclusion Based on available site information and expected excavation depth, it is projected that trenching and excavation for placement of sewer lines and catch basins to the west and east of the collector north-south sewer will be placed entirely within man - placed fill. Installation of the north -south collector sewer may require excavation into native soils; it is estimated that the maximum depth of excavation into native soil would be approximately 1 foot. The deep excavation in the southeast corner of the West Parcel for installation of the Stormceptor water quality unit is expected to extend no more than 1 foot into the native soils underlying man- placed fill, but the excavation could extend up to 5 feet into native soil if a localized high point is encountered. Available information for the site indicates that filling of the property occurred over about a 7 year period and was likely completed by 1920.

As soon as I've refined them I'll send you the draft conditions. I am meeting tomorrow with Public Works staff and will let you know if there are any additional engineering comments. I had the permits a little out of sequence as far as their consideration and approval. Once SEPA is issued, well schedule & hold the shoreline variance hearing, as the decision on that permit may affect the shoreline permit (i.e. if the variance isn't granted or the hearing examiner adds some conditions that affect the shoreline permit). After the decision on the shoreline variance is issued by the Hearing Examiner we can issue the shoreline permit, then proceed to a decision on the administrative design review and finally the short plat. Could you please have the architecture firm contact me regarding the change in the main building color? I would like to resolve this issue so that I can finalize the staff report for this permit.

Response: No. The water quality /wet pond note on Sheet C -1 has been removed as the site will utilize the Stormceptor® for the on -site water quality system. 7. Your comment #6 states that a work plan for addressing the contamination on the eastern portion of the site was included –1 did not find that enclosure. Response: Six copies of the Draft East Parcel Cleanup Work Plan prepared by Geomatrix Consultants, Inc., dated November 2005 are enclosed. 8. Your comment #12 states that the Operation, Monitoring, Inspection and Maintenance Plan was included —1 did not find that enclosure. Response: Please see the enclosed Revised Operation, Monitoring, Inspection, and Maintenance Plan prepared by Geomatrix Consultants, Inc., dated February 2006. 9. Is there a contingency plan for relocating the wells after re- paving if using the metal detector does not work? Response: Several precautions have been taken to ensure that monitoring wells specified for continued monitoring will be returned to service after completing redevelopment of the western parcel. In addition to placing the metal plates over the wellheads, the location of each well has been surveyed by a licensed surveyor. If attempts to locate a buried well using a metal detector are unsuccessful, the known location will be surveyed. The metal detector and a GPS locator will be used initially to locate the wells after repaving has been completed. If neither the metal detector nor the survey can successfully locate a well, Container Properties will work with the EPA to resolve groundwater monitoring issues. Please note that the EPA has formally approved the redevelopment plan. An Approval with Modifications (enclosed) was issued by the EPA on March 29, 2006. The modification requested by EPA has been made. The following comments are provided as information items that will be addressed at the building permit stage: 1. During a site inspection on January 27, 2006, it was noted that the filter fence along the western boundary of the site does not extend to the berm, leaving a gap which could allow sediment to enter the river. Prior to any grading on the site, the filter fence must be corrected. Response: Comment noted. 2. For the building permit, please provide details on the wheel wash and its proposed location. Response: Comment noted. • Ms. Carol Lumb City of Tukwila Department of Community Development -4- April 7, 2006 3. The approximate location of the personal decontamination station should be shown on the plans. Response: Comment noted. This will be completed with the Building Permit plans. 4. The Western Parcel Redevelopment Work Plan prepared by Geomatrix recommends using a Vortechs water quality system for stormwater treatment while Sheet C -4 shows a stormceptor as the water quality control feature. The building permit drawings should clarify which structure will be used. Response: A Stormceptor® will be installed and utilized as the water quality control feature. Building Permit drawings will reflect this information. S. The building permit shall include a design approval letter from the storm water treatment manufacturer and a storm drainage maintenance schedule that clearly stats who, what, when and how maintenance will be performed. This must be in a format acceptable to King County for recording. Response: Comment noted. 6. Traffic impact fees, based on the 2006 Traffic Impact Fee Schedule, will be levied as part of the building permit. Response: Comment noted. We believe that the above responses, together with the enclosed revised plans and other documents, address all of the comments in your letter dated March 2, 2006.

NAME: Former Rhone- Poulenc Site Tukwila, Washington SUBJECT: Depth of Fill at Former Rhone - Poulenc Site This memorandum discusses the depth of fill materials in the western portion of the former Rhone- Poulenc facility located at 9229 E. Marginal Way South, in Tukwila, Washington. The portion of the site proposed for installation of a new stormwater system is referenced in this memorandum as the West Parcel. Plans and applications have been filed with the City of Tukwila to support installation of a new stormwater system, grading to promote drainage, and paving to support use of the area for warehousing and storage of automobiles within the West Parcel. This assessment of fill depth is being made to evaluate the potential for exposing or excavating native materials during the work planned for the West Parcel. Of the planned activities, only installation of the new stormwater management system will require excavation. Background The former Rhone- Poulenc site is located adjacent to the Duwamish Waterway, just to the north of "Slip 6 ". Slip 6 is a former channel of the Duwamish River. The Duwamish River was dredged and straightened from 1913 through 1920; the portion of the river adjacent to the former Rhone- Poulenc site is now referred to as the Duwamish Waterway. Based on available documentation (CH2M HILL, 1995; Landau, 1991), much of the property, especially the western portion, consisted of tidal flats. It is likely that much of the West Parcel was submerged at high tide prior to filling of the area. Although no specific records are available, the majority of the property was probably filled at the time that the waterway was dredged; the typical practice was to slurry the hydraulically dredged material onto the land surface using a system of pipes. It is expected that the site was filled some time between 1913 and 1920, when the waterway was constructed. Since the dredge material was derived from river sediments, the fill materials (sands and silts) resemble the materials native to the site prior to dredging. Approximately two acres of tide flats remain along the western side of the property. J: \8769.000 RCI R -P \086 \Fill Depth Memo_FINAL.doc One Union Square. 600 University Street. Suite 1020 Seattle. Washington 98101.4107 Tel 206.342.1760 Fax 206.342.1761 www.geomacrix.com RECEIVED TAPR 07 2006 COMMUNI I Y DEVELOPMENT ATTACHMENT B Geomatrix Memorandum April 6, 2006 Page 2 of 4 • • Depth of Man- Placed Fill Site investigation reports and lithologic logs for wells and soil borings that were completed onsite were reviewed to assess the present depth of fill at the former Rhone- Poulenc site. The RCRA Facility Investigation Report prepared by CH2M HILL reported that "... hydraulic fill consisting of dredged sand and silt is present in the upper 5 to 15 feet of the subsurface." The CH2M HILL report refers to the entire site and is not limited to the West Parcel. It is likely that the western portion of the site, near the waterfront, has a greater depth of fill than the eastern portion which borders East Marginal Way South. The boring logs prepared for the site characterize observations using standard soil classifications, but do not distinguish between fill and native materials. However, review of the boring logs shows a consistent layer of silt at a depth of 5 to 15 feet below the present surface grade over much of the site. This silt layer is distinguished from similar materials by its reported density and the presence of organic material such as plant roots. The depth of the fill materials reported by CH2M HILL and the description of the site as a "tide flat" prior to development suggest that the layer of silt present at the site may represent the historic surface of the original tide flat. The elevation of the silt layer in soil borings is approximately the same as the present elevation of the tide flats on the west side of the property. Other indicators, which can be used to distinguish between fill and native materials, are the presence of recent man -made objects or debris noted in the boring logs. If such material is noted in the log, the material would be considered to be fill material. The boring logs for the southeastern corner of the West Parcel, nearest the planned location for installation of the Stormceptor®, indicate that the depth of fill ranges from about 6 to 12 feet below existing grade. The "ordinary high water mark" shown on the recent survey map of the site is shown at approximately 5 feet in elevation, which is approximately 12 feet below present grade. It is likely that the elevation of the former tide flats was probably no greater than 1 to 2 feet above the ordinary high water mark, or at an approximate elevation of 6 to 7 feet above mean sea level. The projected elevation of the former tide flat suggests that there is approximately 10 to 11 feet of fill in the southeast corner of the West Parcel. Available information from previous site investigation reports and from more recent boring logs indicate that the depth of man - placed fill within the West Parcel is generally 5 to 12 feet below the current site surface. In the southeast corner of the West Parcel, the expected depth of fill is 10 to 11 feet, but localized areas may be only about 6 feet in depth. In most locations, the presence of native soil can be identified by the presence of a silt layer. The native soils were exposed as recently as 85 to 90 years ago. J: \8769.000 RCI R -P \086 \Fill Depth Memo_FINAL.doc Geomatrix Memorandum April 6, 2006 Page 3 of 4 • • Depth of Excavation During redevelopment of the West Parcel, limited excavation will be conducted to install underground storm sewers and an underground stormwater treatment unit. Final elevations will be attained by importing clean fill. Grading of soils presently onsite will be limited to elevated areas presently beneath building floors and other localized mounds. Grading has been designed to limit disturbance of surficial materials which may have been contaminated by historic industrial activities at the site. All grading will disturb only fill material. Therefore, only the limited excavation to install the stormwater management system has potential to disturb native soils. Installation of the stormwater system will require excavation of trenches for sewer and catch basin installation and a larger excavation to install a Stormceptor water quality unit. Trench excavations will be distributed over much of the West Parcel. Most of the trenching will be limited to depths from 4 to 6 feet below existing grade. The deepest trenching will be for the collector stormwater lines running north -south in the eastern portion of the West Parcel. The collector lines leading to the Stormceptor unit will be excavated to a maximum depth of about 7 feet below existing grade. As noted above, the approximate depth of fill is 5 to 7 feet in the area where the collector storm sewer will be located. The deepest excavation will be for installation of the Stormceptor water quality unit and for discharge piping running to the existing 36 -inch storm sewer entering the eastern end of Slip 6. The projected excavation depth is approximately 11 feet below existing grade. The location of the Stormceptor is near the southeast corner of the West Parcel, just north of the eastern end of Slip 6. It is expected that all soil above and adjacent to the existing 36 -inch sewer line consist entirely of man - placed fill. Conclusion Based on available site information and expected excavation depth, it is projected that trenching and excavation for placement of sewer lines and catch basins to the west and east of the collector north -south sewer will be placed entirely within man - placed fill. Installation of the north -south collector sewer may require excavation into native soils; it is estimated that the maximum depth of excavation into native soil would be approximately 1 foot. The deep excavation in the southeast corner of the West Parcel for installation of the Stormceptor water quality unit is expected to extend no more than 1 foot into the native soils underlying man - placed fill, but the excavation could extend up to 5 feet into native soil if a localized high point is encountered. Available information for the site indicates that filling of the property occurred over about a 7 year period and was likely completed by 1920.

Marginal Way Facility WAD 00928 2302 • ift ; o ./e) toje The U.S. Environmental Protection Agency, Region 10 ( "EPA ") has completed Its review of the Westem Parcel Redevelopment Work Plan ( "Redevelopment Work Plan ") dated November 14, 2005. The Redevelopment Work Plan includes spedflcations for well abandonment, earthwork, storm water management, well retrofitting, paving, and re- fencing to be conducted In the western portion of the Fadlity, co- located with the existing approved subsurface Hydraulic Control Interim Measure. These activities are proposed in order to enable this portion of the Facility to be leased to a tenant for storing and auctioning vehicles. Comments regarding the Redevelopment Work Plan are enclosed. Pursuant to Section VILA of the Order, the Redevelopment Work Plan must be revised to fully address these comments.. In accordance with Paragraph 7.3 of the Order, Respondents must submit a revised final Redevelopment Work Plan Including all revisions specified above to EPA within thirty (30) calendar days of receipt of this letter. Respondents are cautioned that the work set forth In the Redevelopment Work Plan is scheduled to occur prior to the approval of a Corrective Measures Study and selection by EPA of a flnal corrective measure. The process of selecting a corrective measure Is subject to public review and comment, Tribal consultations, and consultations with other federal agencies under the Endangered Species Act. This work could be in conflict with work that EPA determines is required to be conducted under. the Order, and is, thus, being undertaken at the Respondents' risk. For example, aspects of this redevelopment work could be required to be redone or disturbed to the extent that they are determined by EPA to be inconsistent with work required under the Order. In additjon, the tenant's operation of the site could be interrupted by future work that is required under the Order. Nothing in the Redevelopment Work Plan, or EPA's communication relating to it, alters or affects Respondents' existing responsibilities and obligations under the Order. 0 re rwoa odaper .

Jurisdiction and Approval Authority. The Westem Parcel Redevelopment Work Plan ( "Redevelopment Work Plan ") includes descriptions and specifications for work to be conducted under several regulatory jurisdictions. It is difficult to ascertain, as written, which sections require EPA's review and approval, which sections constitute modifications of previously approved work plans and . .which sections were provided for information. Work that requires EPA's approval under the Order includes source removal, sampling procedures and Quality Assurance Project Plans (QAPPs) to be utilized in the event grading uncovers contaminated sofas, and engineering plans and specifications for the paving If It Is to be approved as a new interim measure (see General Comment No. 6). Work that requires EPA approval of modifications to previously approved work plans includes changes to site security plans and modifications to the protective cap over the barrier wall. Other portions of the Redevelopment Work Plan, such as the storm water management plan and the State Environmental Policy Act (SEPA) checklist, may require approval from other regulatory jurisdictions such as the Slate, King County and /or the City of Tukwila; or are provided only for Information, such as the lease. The Redevelopment Work Plan must be revised, at a minimum, to clearly Identify provisions and/or work which constitute a modification to previously approved work plans, or otherwise require EPA's approval under the Order. EPA's approval will be limited to those portions of the Redevelopment Work Plan, and will not include other provisions such as the lease. Stormwater Pollution, Prevention Plan, Health and Safety Plan, or SEPA checklist. Note that it would be helpful if the lead agency for each of the other sections of the Redevelopment Work Plan were also clearly identified. 2. Source Removal. Prior to Redevelopment The Redevelopment Work Plan must be revised to describe the work that has been and/or will be done to remove and/or abandon the remaining sumps and vaults present at the facility. EPA has received the 'Affected Soil Removal Plan," dated January 24, 2006," which addresses removal of surface soil in the northwestem comer of the Facility. Comments regarding the January 24 soil removal plan will be forwarded under separate cover. Respondents should note that there may be other areas of the Facility that contain sources of contamination that EPA will determine need to be addressed prior to achieving a corrective action complete determination. Respondents undertake this redevelopment at their own risk knowing that a Corrective Measures Study has not been approved by EPA; EPA has not yet selected a remedy; the work done now may be disturbed in the future; and operations at the Facility may be interrupted by future work required under the Order. P. 4 MAR . 27 2006 1 1 : 18HM HP LHSLI1Jt I ,ieUU 3. Site Security. (Pages,2, 10, and Appendix E.) Page 10 of the Redevelopment Work Plan indicates that new security fencing will be installed along the eastem boundary of the westem parcel. This page states that access to the westem parcel is to be through the Tenant's adjoining facility to the north. The treatment building, extraction wells, assodated piping, and at least some of the monitoring wells will be located Inside this fenced area on the western parcel. Drawing 3 of Appendix C, however, appears to indicate that gates will be located in the new boundary fencing between the eastem and western parcels. This drawing does not indicate that there will be access gates along the northern fence line. This drawing also appears to indicate the presence of a double fence.along the western site boundary. If accurate, several of the monitoring wells will be located between these fences, although no gates are indicated. The drawing also seems to indicate a double fence located at thetop of the bank of Slip 8. Further confusion is introduced on page 1, where the second to last full sentence Indicates that the development activities will include construction of a permanent fence "along the westem parcel boundaries," implying that all of the fencing will be replaced. The Redevelopment Work Plan must be revised to include . a figure clearly indicating where the security fence(s) and access points will be located, and this figure must be consistent with the text. The Tenant's adjacent premises. appear to be open to the public during the day. The Redevelopment Work Plan does not state whether the western parcel will be open to the public as well. The Redevelopment Work Plan must be revised to specify how site security will be established and maintained If there is to be public use of the westem parcel during business hours. For example, how will the treatment building and weU heads be secured? Where will warning signs be installed and what will they state? How will piping and andllary equipment be protected? Page 2 of the Redevelopment Work Plan indicates that "security will be provided by IAAI" after installation of the new security fencing. Changes to the security fendng require a modification of the approved Hydraulic Control interim Measures Work Plan. In addition, this sentence must be revised to clarify that the terms of the lease do not obviate the Respondents' responsibilities and obligations under the Order and the approved Hydraulic Control Interim Measures Work Plan to provide and maintain • adequate security for the Facility. 4. Access. (Pages 3, 10, and 11.) Several sections of the Redevelopment Work Plan indicate that the lease includes provisions to ensure that the interim measure facilities and monitoring wells can be freely accessed "for routine operation and for groundwater monitoring" after control of the parcel is assumed by the Tenant. As discussed later in these comments, however, the lease only provides access "after reasonable advance written notice from Landlord" (page 6 of lease agreement). This provision does not provide EPA with access as required by Paragraph 10.1 of the Order. Paragraph 10.1 of the Order requires that, if the Facility is locked or otherwise closed to workers and visitors during regular business hours or at an otherwise reasonable time, the Respondents make the Facility accessible to EPA within four (4) hours of oral notice of EPA's intent to enter the Facility. The Redevelopment Work Plan must be revised to comply with the Order. Additionally, while the lease does require the Tenant to allow the Landlord or EPA to enter the premises to conduct work, the lease does not appear to include provisions to maintain or obtain physical access to the interim measure facilities and monitoring wells or access for later corrective measures implementation or other work that may be required under the Order. The Redevelopment Work Plan must be revised to specify how ready access to wells, treatment equipment, and/or the barter wall cap will be assured it for example, vehicles are parked on or In front of them and to address access for other work that may be required under the Order. r MHK , e / dUUb 1 1 : 1 JHM Hr LHbLKJ .

The Redevelopment Work Plan must bd revised to specify what measures will be taken to ensure that the existing interim measures facilities are adequately protected from the Tenant's activities on the site. For example, the Redevelopment Work Plan must clearly specify if all wells are to have flush- mounted surface completions rather than protective barriers. Are there restrictions on the Tenant's activities within a specified distance of the building which houses the treatment plant? Is digging or other reconstruction prohibited? Is the Tenant required to immediately notify Respondents of any damage to or problems observed with the interim measure (e.g., leaks, cracking pavement etc.)? 6. ' Capping. (Pages 10 and 23.) The Redevelopment Work Plan must be revised to clearly state whether the asphalt paving Is being proposed as a new interim measure (a cap to control run-on and run-off and prevent exposure to soils) in addition to the existing, approved hydraulic control interim measure. If the asphalt paving is being proposed as an additional interim measure, the Redevelopment Work Plan must indude design specifications, run-on and run-off control measures and supporting calculations, a construction quality assurance plan, etc. in accordance with applicable guidance forRCRA caps. The Redevelopment Work Plan must also be revised to consistently provide the thickness of paving to be used at the site; page 10 indicates that 4" of asphalt will be used, white page 23 indicates that 3' of asphalt will be used. The Redevelopment Work Plan must also be revised to dearly demark the areas of the facility where a cap has already been approved and installed as a protective cover for the barrier wall (see pages 5-15 and Appendix A, Drawing 8 of the December 2, 2002 Hydraulic Control Interim Measures Construction Work Plan). This protective cover over the barrier wall must be retained and maintained as required. Provide engineering drawings and technical specifications for extending the cap to the new grade. Provide procedures for installing and locating the settlement plates, and correlating the new surface elevation to the top of the barrier wall so that the wall may continue to be routinely monitored for subsidence as .required by page 8-8 of the Hydraulic Control interim Measures Work Plan. Once again, Respondents are cautioned that the work set forth in the Redevelopment Work Plan is scheduled to occur prior to the approval of a Corrective Measures Study and selection by EPA of a final corrective measure. The process of selecting a corrective measure is subject to public review and comment; Tribal consultations, and consultations with other federal agencies under the Endangered Species Act For example, discussions regarding the original placement of thebarrier wall induded conversations about retaining a fifty (50) foot setback for habitat restoration at the time the site was paved, while the Redevelopment Work Plan appears to indicate • that the pavement on the westem parcel will extend within fifty (50) feet of Slip 6. (E.g., see page 7, Section 3.0, last bullet) Additionally, please be reminded that EPA has not established final soil cleanup levels for the Facility, and has not reviewed the available site data to determine that no further source removal will be necessary. The work proposed in the Redevelopment Work Plan could be in conflict with final corrective measures that EPA determines is required to be conducted under the Order, and is, thus, being undertaken at the Respondents' risk.

Provide the schedule for submission of a construction report, including all components specified on page 7-2 of the approved Hydraulic Control Interim Measures Construction Work Plan. Also provide the schedule for submission of a revised Operating and Maintenance Plan incorporating all changes necessitated by this redevelopment. 13. Appendix B, SEPAIShorellne Application. EPA has not reviewed this document in its entirety, as EPA is not the lead agency for SEPA review. However, EPA wishes to note several inaccuracies in this document. Specifically, the first page 2 states that the subject property is "a registered . Superfund site ". The second page 4 again states the property is a Superfund site, and further indicates that an Operation, Monitoring, Inspection and Maintenance Plan will be reviewed and approved by EPA prior to the redevelopment activities. Page 6 indicates the project site is an "unused storage yard closed in 1991." These statements are inaccurate: the site is not being addressed using Superfund or CERCLA authority, but rather is subject to a RCRA compliance order for cleanup; the Operations and Maintenance Plan is not scheduled to be submitted to EPA prior to commencement of the redevelopment; and its approval bears no relation to the redevelopment activities; and lastly, the project site was an active chemical manufacctiuing facility for 50 years prior to becoming an unused storage yard. 14. Appendix E, Insurance Auto Auctions Lease, page 5. Number 8, °Utilities; indicates that the "Landlord shall not be responsible for providing any utilities to the Premises" Revise the Redevelopment Work Plan to clarify how Respondents will ensure that continuous utility services such as electricity are to be provided for operation of the Interim measure. 15. Appendix E, Insurance Auto Auctions Lease, page 6. Number 11, "Repairs and ' Maintenance," indicates that the "Tenant shall at its sole expense maintain the Premises ... and make all repairs .... The Redevelopment Work Plan must be revised to clarify how the Respondents will ensure that all approved caps will be maintained and repaired in a manner consistent with the approved work plans. The Redevelopment Work Plan must also be revised to specify how the Respondents will ensure that all security measures, including the fence, remain effective and in good condition. 16. Appendbc E, Insurance Auto Auctions Lease, page 8. Number 12, "Access," requires that after reasonable advance written notice from Landlord, except in case of emergency, Tenant shall permit Landlord or the agendas, including EPA, to enter the Premises at all reasonable times for purposes of repair, environmental remediation, inspection, ground water sampling, etc. This provision does not provide EPA with access as required by Paragraph 10.1 of the Order. Paragraph 10.1 of the Order requires that, if the Facility is locked or otherwise closed to workers and visitors during regular business hours or at an otherwise reasonable time. the Respondents make the Facility accessible to EPA within four (4) hours of oral notice of EPA's intent to enter the Facility. The Redevelopment Work Plan must be revised so that it is consistent with the Order.

This revision was prepared in response to EPA's comments dated February 9, 2006. Pursuant to Paragraph 7.1 of the Order, the revised Western Parcel Redevelopment Work Plan is hereby conditionally approved with modification. EPA's approval is conditioned on Respondents modifying the final revised Westem Parcel Redevelopment Work Plan as directed by EPA in this letter. Page 2 of the revised Western Parcel Redevelopment Work Plan is hereby modified as follows: Delete the seventh sentence of Section 1.1, which states that Container Propertes has primary responsibility for implementing the provisions of the Order. All Respondents are equally responsible for implementation of work plans and overall compliance with the Order. Please submit a revised page 2 of the Westem Parcel Redevelopment Work Plan, including the revision specified above, within thirty (30) days of receipt of this approval with modification as set forth by Paragraph 7,2 of the Order. The effort and care that went into preparation of the final Western Parcel Redevelopment Work Plan is evident and is appreciated. The high quality of the final document has allowed EPA to approve the revised work plan quickly. Printed on Recycled Psper • Respondents are cautioned that the work set forth in the Redevelopment Work Plan is scheduled to occur prior to the approval of a Corrective Measures Study and selection by EPA of a final corrective measure. The process of selecting a corrective measure is subject to public review and comment, Tribal consultations, and consultations with other federal agencies under the Endangered Species Act. This work could be in conflict with work that EPA determines is required to be conducted under the Order, and is, thus, being undertaken at the Respondents' risk. For example, aspects of this redevelopment work could be required to be redone or disturbed to the extent that they are determined by EPA to be inconsistent with work required under the Order. Nothing in the Redevelopment Work Plan, or EPA's communication relating to it, alters or affects Respondents' existing responsibilities and obligations under the Order.

During the 30 -day public comment period, which ended on February 23, 2006, one comment letter was received from the Muckleshoot Indian Tribe. A copy of the letter is enclosed and a response to the issue raised in the letter is needed prior to issuance of SEPA. 2. King County Code 25.16.030 E.2. requires at least five feet of landscaping to screen parking areas — please revise the landscape plan to show 5 feet of landscaping on the western edge of the site where cars will be parked as part of the lease of the property to Insurance Auto Auction. 3. Thank you for providing a copy of the easement granted by Monsanto Chemical Company to the four railroad companies. Unfortunately, the lower portion of the easement language on the first page is not legible (see enclosed copy). Please provide a copy that can be easily read. 4. The SEPA Checklist states that the building to be constructed will be 185,000 sq. ft. in size; Sheet P1 of 2 shows a building that is 84,000 sq. ft. in size — which is correct? 5. Please revise the Benjamin Moore color #1177 to use a less pink and more tan -toned color to better complement the green tones that are being used for accent. See the enclosed photo simulation of color #1177 on the body of a building. 6. Sheet C -1 shows a water quality /wet pond — will this be used in addition to the stormceptor system that is shown on Sheet C -4? 7. Your comment #6 states that a work plan for addressing the contamination on the eastern portion of the site was included -- I did not find that enclosure. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 Ms. Ivana Halvorsen Barghausen Engineering March 2, 2006 8. Your comment #12 states that the Operation, Monitoring, Inspection and Maintenance Plan was included — I did not find that enclosure. 9. Is there a contingency plan for relocating the wells after re- paving if using the metal detector does not work? The following comments are provided as information items that will be addressed at the building permit stage: 1. During a site inspection on January 27, 2006, it was noted that the filter fence along the western boundary of the site does not extend to the berm, leaving a gap which could allow sediment to enter the river. Prior to any grading on the site, the filter fence must be corrected. 2. For the building permit, please provide details on the wheel wash and its proposed location. 3. The approximate location of the personal decontamination station should be shown on the plans. 4. The Western Parcel Redevelopment Work Plan prepared by Geomatrix recommends using a Vortechs water quality system for stormwater treatment while Sheet C -4 shows a stormceptor as the water quality control feature. The building permit drawings should clarify which structure will be used. 5. The building permit shall include a design approval letter from the storm water treatment manufacturer and a storm drainage maintenance schedule that clearly stats who, what, when and how maintenance will be performed. This must be in a format acceptable to King County for recording. 6. Traffic impact fees, based on the 2006 Traffic Impact Fee Schedule, will be levied as part of the building permit. Please let me know if you have any questions. 1 can be reached at 206 - 431 -3661.

The 9229 East Marginal Way South property is an area the Tribe has flagged as high potential for archaeological discovery. The project area location is one that the Tribe considers to have a high probability for archaeological resources, because there are previously identified archaeological sites and a traditional cultural place nearby. Although the proposed project area appears to be previously disturbed, I cannot tell from the information provided whether the proposed construction could intersect native soils on -site. If that is a possibility, then we request that an archaeological study be conducted of the project area to determine the best means of identifying and protecting archaeological resources that may be uncovered during construction. If the applicant believes that construction would take place entirely within fill, we request supporting documentation, such as a comparison of construction plans and soil profile information. Information regarding previous surveys and recorded archaeological sites is available from the Office of Archaeology and Historic Preservation, in Olympia. The Cultural Resources Program does not represent the Wildlife Program and the Fisheries Program which are separate departments under the Muckleshoot Indian Tribe. Please contact these departments separately for their input on this project. We appreciate the effort to coordinate with the Muckleshoot Tribe prior to site preparation. The destructive nature of construction excavation can often destroy a site and cause delays and unnecessary expense for the contractor. If you have any questions, please contact me at 253- 876 -3272.

The following comments are provided for your review and must be addressed before further work will occur on the files. Background: The site is regulated under the Resource Conservation and Recovery Act (RCRA) and subject to a RCRA corrective action under Administrative Order of Consent #1091-11-20 - 3008(h). Under a previous SEPA action (E02 -021), a subsurface barrier wall encircling contaminated groundwater was constructed. The wall is approximately 2300 linear feet and 50 to 70 feet deep. The current remediation work (groundwater barrier, recovery wells, pretreatment system and discharge to sanitary sewer) is only an interim measure. Additional site clean -up will likely be needed in the future and may involve remediation along the river bank and along Slip 6, including possible sediment removal. There is some question about the effectiveness of the current system, particularly related to the location of the recovery wells. Groundwater monitoring will begin soon to evaluate the effectiveness of the system. Per EPA, the proposed Operation, Monitoring, Inspection and Maintenance Plan that is mentioned in the SEPA Checklist applies only to operation of the interim groundwater recovery and treatment system and not to any other activities at the site (such as grading). A separate health and safety plan will be needed for site grading /filling activities. CL q: \David -Rhone Poulenc \Technical Comments.doc Page 1 of 5 10/27/2005 12:10 PM Steven M.

As noted at the Pre - Application meeting on December 2, 2004, this site is governed by the King County Shoreline Master Program, not Tukwila's. The materials submitted with L05 -050 address Tukwila's shoreline criteria rather than King County's. A copy of King County's criteria is attached — please submit a response to K.C.C. 25.16.030 and K.C.C. 25.16.170. 2. Since the site is governed by King County's Shoreline Master Program, please revise all plans showing the shoreline environments to reflect the King County setbacks rather than the City of Tukwila shoreline environments (River, Low Impact and High Impact). L05 -051: Shoreline Variance 3. The Variance Request states that "(T)o efficiently utilize the site, strict application of the bulk, dimensional, and performance standards (disallowing parking waterward of the structure) would create net loss of parking that cannot be reallocated on site." It appears there is room to flip the building orientation such that the parking is located on the north side of the proposed warehouse and the drive aisle is located on the south side. In addition, the site plan shows 201 parking stalls, when only 93 would be required for a 185,000 sq. foot warehouse. Since the site is over - parked, it would seem that the parking stalls in the shoreline can be eliminated. L05 -055 Administrative Design Review 4. In a letter dated September 14, 2005, we requested building elevations, color and materials board, lighting plan and illustrations of any signage planned for the site. These materials are needed before Notice of Application can be issued. L05 -057: Short Plat 5. The short plat proposes to segregate off the portion of the site that is subject to the RCRA Consent Decree. We are concerned that since only interim remediation actions have been taken so far to clean up the contamination, a short plat would possibly create on non - buildable lot if the remediation efforts are not successful. In addition to the known contamination, we understand there is concern over what might be in the underground piping and tanks. No information was provided to the current owner about these issues when the property was sold. Please address this concern. 6. It is our understanding that some minor areas of soil contamination exist on the eastern part of the site. Explain how and when these will be dealt with and identify the location of the contaminated areas. CL Page 2 of 5 10/27/2005 12:10 PM q: \David -Rhone Poulenc\Technical Comments.doc J Ms. Ivana Halvorson Barghausen Engineering Davis Property, 9229 East Marginal Way South October 27, 2005 Corrections to Plans: 7. Revise the plans to show the three groundwater recovery wells in addition to the monitoring wells. 8. The plans must indicate where the existing groundwater pretreatment facility is located, as well as the proposed new location. In addition, both existing and proposed piping details must be provided on the plans. 9. The plans must indicate the current location of the on -site King County lift station and indicate whether it will also be relocated. 10. It is unclear from review of the documents provided how the groundwater recovery wells, the groundwater pretreatment system piping, monitoring wells, and the upper surface of the slurry walls will be protected during grading and construction. Please explain, and if appropriate, provide revised drawings. SEPA Checklist: 11. Section B.1. item f. The response to the question of whether erosion could occur as a result of clearing, construction, or use, does not make any sense. The slurry wall does nothing to protect sediment from leaving the site, as it is below ground and was constructed to intercept groundwater, not surface water. 12. Section B.7. items 1 and 2. The City should be provided with a copy of the EPA - approved Operation, Monitoring, Inspection, and Maintenance Plan referenced in the SEPA Checklist. 13. A detailed health and safety plan will be necessary for any grading/filling work on the site, including emergency measures and daily decontamination procedures. Please provide the City with a copy of the plan for the SEPA file when it has been prepared. Landscaping Plan 14. Since a variance is being requested from the King County shoreline requirement to place parking either under buildings or landward of the shoreline, please provide a • schematic that shows how the landscaping adjacent to the shoreline will look one year after planting and three years after planting. 15. Please enlarge the portion of the proposed landscaping for the streetscape and the front of the building — it is difficult to identify all the plants that are proposed for these locations.

Please confirm the location of the Cornus Kousa — are these trees proposed along the front of the building? 17. I only count 16 Thuja Plicata `Excelsa.' 18. The common name of Pennisetum Alopecuroides `Hameln' is listed as Oregon Grape, which is incorrect. Please correct the table. 19. Landscaping is required to screen the proposed storage yard from the shoreline. Public Works Comments: 20. Please refer to the Pre - application Meeting comments from Public Works. A copy is included. A number of the items indicated on the Public Works comment sheet were not included or addressed in the submittal materials. Please provide the missing items that are highlighted on the enclosed Checklist. 21. Provide a Traffic Impact Analysis prepared by an engineer licensed in Washington State that includes analysis of turning movements at the existing signalized access and at the proposed additional access. The site plan can not be evaluated properly without knowing what traffic impacts need mitigation. 22. Please provide civil sheet(s) that include: a. All existing easements that will remain after the demolition and all new easements, including access across BNSF property. b. Plans that indicate what will remain after all of the demolition and removal of pipes, catch basins, etc. The plans provided include all of the existing sewer, water, and storm drainage elements, making it difficult to sort out what will remain. Please note that the demolition notes do not correlate to the utility locations on the drawings, so it is difficult to tell what will be removed as part of the demolition. (see sheet E2 for example) c. Any measures needed to alleviate or improve turning movement conflicts at the accesses points. d. Rerouting of the 36" storm drain. (Refer to the Technical Information Report) 23. Provide approval from BNSF to cross property for access.

This site is subject to a RCRA corrective action under Administrative Order of Consent # 1091- 11- 20- 3008(h). The work proposed will involve excavation of approximately 10 test pits, measuring approximately 15 feet deep by 12 feet long by 3 feet wide. The approximate volume of material removed would be 20 cubic yards, for a total of approximately 200 cubic yards. After the soils are tested, the excavated materials will be re- compacted to the current grade. This work is being conducted at the request of the United States Environmental Protection Agency. The test pit excavations will take place within the boundaries of the existing subsurface barrier wall. Construction is being conducted under the existing NPDES General Construction Activities Stormwater Permit for the site. The activities identified above are exempt from a Shoreline Substantial Development permit under WAC 173 -27 -040 (3), Hazardous substance remedial actions.

I reviewed the "Interim Measures Construction Work Plan (URS 2002) in our files to get a better understanding of the contamination issues, the location of the groundwater recovery wells, and the pre- treatment system (none of which is shown on the plans). I think the City should ask for a copy of EPA's approval of the actions to be taken on -site. I would like to speak with the EPA project manager to get an update on what is going on at the site and what future clean -up actions (if any) were contemplated. I also would like to understand who will have responsibility for ongoing operation, maintenance and monitoring of the groundwater treatment program. I have left a message with the project manager at EPA. Plans: • • 1. The plans should show the three groundwater recovery wells in addition to the monitoring wells. 2. The plans should indicate where the existing groundwater pretreatment facility is located and as well as the proposed new location. In addition, piping details should be provided on the plans — both existing and proposed. 3. The plans should indicate current location of the on -site King County lift station and indicate whether it will also be relocated. 4. It is unclear from review of the documents provided how the groundwater recovery wells, the groundwater pretreatment system piping, monitoring wells, and the upper surface of the slurry walls will be protected during grading and construction. SEPA Checklist: 5. Section B.1., item f. The response to the question of whether erosion could occur as a result of clearing, construction, or use, does not make any sense. The slurry wall does nothing to protect sediment from leaving the site, as it is below ground and was constructed to intercept groundwater, not surface water. 6. Section B.7., items 1 and 2. The City should be provided with a copy of the EPA - approved Operation, Monitoring, Inspection, and Maintenance Plan referenced in the SEPA Checklist. The plan should include a very specific and detailed health and safety plan, including emergency measures and daily decontamination procedures. It is not enough to make the plan available to site contractors — they have to receive training in the health and safety procedures. In addition, site workers will need specialized OSHA training/certification in order to carry out the work.

(Container Properties) is currently planning redevelopment for a portion of their property at 9229 East Marginal Way, Tukwila, Washington. This property is the site of the former Rhone- Poulenc East Marginal Way facility. This facility was used for production of glue, resins, paints, and vanillin production from 1952 until 1991. Container Properties purchased the site in 1998. Container Properties, as part of the site redevelopment plans, has been requested by U.S. EPA to perform an investigation of several areas on site The approach for the investigation will involve excavation of test pits to an anticipated maximum depth of 15 feet below ground to the base of former below- ground structures at the site. A figure is attached to this letter showing locations of the proposed test pits for reference. All of the test pit locations are within the 200-foot wide shoreline zone. Each test pit will measure approximately 15 -feet deep x 12 -feet long x 3 -feet wide; the volume of material removed from each test pit would be approximately 20 cubic yards, Ten test pits are planned for installation at the site within the 200 -foot shoreline zone. A total of 200 -cubic yards of soil will be excavated in total from these ten test pits, which is less than the 500 -cubic yards threshold. After the test pits have been completed, the excavated materials will be recompacted to the current grade. This activity will take place entirely within the boundaries of the existing subsurface barrier wall at the facility. Construction activities at the site are being conducted under the existing National Pollutant Discharge Elimination System (NPDES) General Construction Activities Stormwater Permit for the site. Container Properties would like to request an exemption from the substantial development permit process as stated under Washington Administrative Code (WAC) 173 -27 -040 (2)(m).

The project site is located within a portion of the south half of Section 33, Township 24 North, Range 4 East, Willamette Meridian, City of Tukwila, King County, Washington. More particularly, the site is located on the southwest corner of South 92nd Street and East Marginal Way South adjacent to the Duwamish River and just north of Slip No. 6, which is owned by the Port of Seattle. The proposal for this development is to construct one large building located in the eastern portion of the site and paving the vast majority of the remainder of the site with a smaller area set aside for landscaping. There is an existing 36- inch - diameter pipe coursing southwesterly through the central portion of the project site that will be rerouted around the building and utilized for the discharge point for the new catch basin, collection, and conveyance system, including a water quality feature to discharge off site into Slip No. 6. Flow control is not a requirement for this project site since there is direct discharge into Slip No. 6 in the Duwamish Waterway. The method of water quality for this project site is to provide a stormceptor for each of the two basins on site, ultimately draining into the 36- inch - diameter storm drain discharging into Slip No. 6. Please refer to Section 4.0 of this report for the sizing calculations to size the stormceptors. 10265.004.doc • r FIGURE 1 VICINITY MAP • 2003 Ilia ltaFiav: M40 t , z— J rte' Wig ...mirlarmour ANNE Cr I-15 .11511 AY 13' ISEINE S A S 003 0006 Mi s AY on AY AY irMAMOMMTO VIANIMMIMMM5Yrik.7.11'711:1111.11.1.11111111111.M1MVASIK dvH jZ9 33S ■ nAnd S AY HILT H191 AY HiE1 0 SAY 1116 AH3Ht133 S id.

Response: Under existing conditions, the site has direct discharge into the Duwamish Waterway and the proposal for this development is to route all stormwater runoff into the 36- inch - diameter culvert coursing through the center portion of the site and discharge into Slip No. 6, which is part of the Duwamish Waterway; therefore discharge at the natural location is maintained. Core Requirement No. 2: Off - Site Analysis. Response: Please see Section 3.0 of this report for the off -site analysis prepared for this development, of which there is very little. The discharge for the site is direct discharge into the Duwamish Waterway and the upstream basin contributing site is very minimal since the surrounding areas around the project site are all developed and have their own catch basin collection system. The only contributing runoff is from the 36- inch - diameter culvert that drains a large portion of the area upstream from the project site and it is unknown at this time how Large a basin actually contributes to that culvert. Core Requirement No. 3: Flow Control. Response: Core Requirement No. 3 does not apply to this project site since there is direct discharge into the Duwamish Waterway and the City of Tukwila has adopted the 1998 King County, Washington Surface Water Desigi Manual, which states sites that discharge directly into this location of the Duwamish Water do not have to provide Flow Control, only Water Quality. Core Requirement No. 4: Conveyance System. Response: With the Final Technical Information Report prepared for this project, the on -site conveyance system will be sized according to the 1998 King County, Washington Surface Water Design Manual, which allows the Santa Barbara Urban Hydrograph (SBUH) method for sizing conveyance system elements for project sites over 10 acres in size. The SBUH methodology will be utilized for this analysis. Core Requirement No. 5: Temporary Erosion and Sediment Control. Response: When the erosion and sediment control plan is prepared for this development it will conform to all requirements of the 1998 King County, Washington Surface Water Design Manual Appendix D erosion and sedimentation control methods for sites of this nature. Core Requirement No. 6: Maintenance and Operations. Response: This project will concur with all maintenance and operations requirements of the City of Tukwila for projects of this nature. 10265.004.doc • • Core Requirement No. 7: Financial Guarantees and Liability. Response: This project will conform to all City of Tukwila financial guarantee and liability requirements as dictated by the City of Tukwila for projects of this nature. Core Requirement No. 8: Water Quality. Response: This project proposes to locate two stormceptors on the downstream end of the project site, ultimately discharging into a 36- inch - diameter pipe coursing southwesterly through the central portion of the project site, ultimately discharging to Slip No. 6 in the Duwamish Waterway immediately adjacent to the project site. The stormceptors have been sized in accordance with Washington State Department of Ecology requirements as allowed by the City of Tukwila on past projects that have been designed utilizing stormceptors. This requires 80 percent total suspended solids removal and 91 percent of the annual flow treated at a minimum. 2.2 Analysis of the Five Special Requirements Special Requirement No. 1: Other Adopted Area Specific Requirements. Response: This project is not known to be within an area with other adopted area - specific requirements; therefore, this project is not under the requirements of any other basin plan, critical drainage area plan, etc., to the best of our knowledge at this time. Special Requirement No. 2: Floodplain/Floodway Delineation. Response: This project site is adjacent to the Duwamish Waterway and the ordinary high water mark has been surveyed for this waterway. FEMA Maps will be consulted and the 100 -year floodplain boundaries for the site will be shown; however, it is unlikely that the project site is ever inundated by water during a 100 -year event. Special Requirement No. 3: Flood Protection Facilities. Response: This project is not adjacent to a Class 1 or 2 Stream that has a flood protection facility nor does it propose to construct a new or modify an existing flood protection facility; therefore, this requirement does not apply. Special Requirement No. 4: Source Controls. Response: This project will provide water quality source control applicable to the proposed project in accordance with the King County stormwater pollution control manual and King County Code 9.12 since this is a redevelopment project proposing improvements to an existing commerciallindustrial or multi - family site. Special Requirement No. 5: Oil Control. Response: This site is not a proposed high use site; therefore, the requirements of the high -use Oil Control Menu will not be applicable to this project site. 10265.004.doc • 1 3.0 OFF -SITE ANALYSIS 3.0 OFF -SITE ANALYSIS • • The off -site analysis for this project site was based on the survey created by this office and utilized in determining the discharge location for runoff from the project site, which is directly into the Duwamish Waterway. This project site proposes to alter the location of the pipes discharging into the waterway to discharge directly into a 36- inch - diameter storm drain coursing southwesterly through the central portion of the project site and immediately discharging into Slip No. 6 in the Duwamish Waterway. This is direct discharge from this project site and the site does not discharge to any other project site when leaving this site; therefore, the downstream drainage course is not an issue on this project site. The adjoining project sites all have their own catch basin, collection, and pipe conveyance facilities discharging into the Duwamish Waterway and do not drain onto the project site. The total upstream basin contributing to the 36- inch -diameter culvert contributing runoff through the project site underneath the site is not known at this time but it is thought that the culvert contains portions, if not all, of the Boeing Field runoff from upstream. 10265.004.doc KING COUNTY DEPARTMENT of ASSESSMENTS 1...•■■....... ..........or ..w.....•■■ ... mom as WMPO immama *awe. mob..., w ...la 9.C.....■••■• ••••• • ■ •••••■•L ,a0.= '..".. g•••== • ••••■■■•••• ■ de e ....ago■.......

WETLAND EVALUATION SUMMARY: Data was collected in the five categories shown below. Within each category the data was evaluated to produce numerical values. Composite values for each category were produced in order to compare each wetland to other wetlands in its sub -basin and in King County. The result of that comparison was a percentile rank. The percentile is expressed on a scale of one hundred and indicates the percent of wetlands that scored equal to or below that particular site_ For example, a percentile rank of 80 under sub -basin means that the wetland scored equal to or better than 80 percent of all sites within the sub -basin for that evaluation category. NOTE: The percentile ranks are valid only within the individual evaluation category and are intended solely for reference and comparison.

Existing Site Hydrology Under existing conditions, the site is fully developed and is abandoned at this time. Portions of the site consist of gravel surface but the majority of the site consists of buildings and asphalt. The proposal for this development is to demolish all the buildings and remove all the existing development from the project site, regrade the site, repave, and construct a single building located in the eastern portion of the project site. The existing site tends to drain in a westerly direction into the Duwamish Waterway and there are existing catch basin, collection, and pipe conveyance facilities scattered throughout the entire project site that tend to route runoff into the Duwamish Waterway. B. Developed Site Hydrology This project is exempt from Flow Control since it directly discharges into the Duwamish Waterway as allowed by the City of Tukwila and the 1998 King County, Washington Surface Water Design Manual. Since no Flow Control is required, the only requirement would be for Water Quality. The proposal for this development is to route runoff from two different basins on site, one from the east, which is 9.07 acres of impervious surface, and one basin from the west of 6.05 acres of impervious surface, including a new building. All this runoff will be routed to two separate stormceptors, one for each basin, and is sized in the following pages of this report. After routing runoff to the stormceptors and being treated for Water Quality, the runoff will directly discharge into the Duwamish Waterway. C. Performance Standards Flow Control is not a requirement for this project site. The conveyance system capacity standards utilized for this project site will be designed to the Santa Barbara Urban Hydrograph method for determining flow rates for the on -site conveyance system since the project site is over 10 acres in size. The area - specific Water Quality Treatment Menu for this project site allows the use of stormceptors as allowed by the City of Tukwila for redevelopment projects of this nature, which should greatly improve the water quality leaving the project site.

Six (6) copies of the Boundary and Topographic Survey Background: On page 1 of the October 27, 2005, letter, you noted that groundwater monitoring will begin soon to evaluate the effectiveness of the remediation that exists on the site. Please note that the remediation efforts and groundwater monitoring has been an ongoing process for approximately seven years. For clarification regarding the location of recovery wells as well as the effectiveness of the current system, please refer to the enclosed documents prepared by Geomatrix Consultants, Inc. The following outline provides each of your comments in italics exactly as written, along with a narrative response describing how each comment was addressed: L05 -050: Shoreline Substantial Development Permit 1. As noted at the Pre - Application meeting on December 2, 2004, this site is governed by the King County Shoreline Master Program, not Tukwila's. The materials submitted with L05- 050 address Tukwila's shoreline criteria rather than King County's. A copy of King County's criteria is attached — please submit a response to K. C. C 25.16.030 and K.C.C. 25.16.170. Response: Please see the enclosed Shoreline Permit narrative. 18215 72ND AVENUE SOUTH KENT, WA 98032 (425) 251 -6222 (425) 251 -8782 FAX BRANCH OFFICES • OLYMPIA, WA • TEMECULA, CA • WALNUT CREEK, CA www.berghausen.com L05 -051: Shoreline Variance L05 -055 Administrative Design Review • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -2- January 4, 2006 2. Since the site is governed by King County's Shoreline Master Program, please revise all plans showing the shoreline environments to reflect the King County setbacks rather than the City of Tukwila shoreline environments (River, Low Impact and High Impact). Response: The plans have been revised to show King County shoreline setbacks only. 3. The Variance Request states that "(T)o efficiently utilize the site, strict application of the bulk, dimensional, and performance standards (disallowing parking waterward of the structure) would create net loss of parking that cannot be reallocated on site." It appears there is room to flip the building orientation such that the parking is located on the north side of the proposed warehouse and the drive aisle is located on the south side. In addition, the site plan shows 201 parking stalls, when only 93 would be required for a 185,000 sq. foot warehouse. Since the site is over - parked, it would seem that the parking stalls in the shoreline can be eliminated. Response: The proposed building will have a gross floor area of approximately 84,000 square feet, including 12,6000 to 33,6000 square feet of office space (15 to 40 %) and 50,4000 to 71,4000 square feet of warehouse space (60 to 85 %). Parking has been provided to accommodate the maximum amount of expected parking demand as the warehouse building is a "speculative" building that may contain a myriad variation of uses. We have evaluated whether the existing building could be flipped to provide loading on the south side (shoreline side) and parking on the north side. Because of the existing uses on surrounding properties, (heavy industrial uses and storage uses to the north and Boeing Flight Museum property to the south) the orientation of the building, as currently proposed, better suites the proposed use and is more compatible with surrounding properties. The minor amount of parking provided waterward of the proposed building within the shoreline jurisdiction is screened from the shoreline by additional landscaping. The entirety of the parking that falls within the shoreline jurisdiction is necessary parking adjacent to the proposed building. Removal of the proposed 28 stalls within the shoreline jurisdiction adjacent to the building would result in lengthy walking conditions for employees or customers to the future uses within the proposed building. 4. In a letter dated September 14, 2005, we requested building elevations, color and materials board, lighting plan and illustrations of any signage planned for the site. These materials are needed before Notice of Application can be issued. Response: These items are provided in the enclosed plan set. L05 -057: Short Plat 5. The short plat proposes to segregate off the portion of the site that is subject to the RCRA Consent Decree. We are concerned that since only interim remediation actions have been r l • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -3- January 4, 2006 taken so far to clean up the contamination, a short plat would possibly create on non - buildable lot if the remediation efforts are not successful. In addition to the known contamination, we understand there is concern over what might be in the underground piping and tanks. No information was provided to the current owner about these issues when the property was sold. Please address this concern. Response: Container Properties agrees that contamination issues are relevant to the short plat proposal and to future development of the segregated portions of the site. However, the developer is addressing these issues actively and adequately with EPA, Region 10 under the existing Administrative Order on Consent (Order). Work is presently underway to fully address each of the City's concerns identified in this comment, as summarized below. Interim actions have been implemented for the western parcel; the most recent interim measure included construction of a totally enclosing barrier wall surrounding the most highly affected soil and groundwater at the site. This barrier wall provides containment to limit migration of contaminated groundwater from the site and has been proven successful in attaining containment objectives included in the approved work plan. Final remediation has not been implemented at the site; additional work, including preparation of the Corrective Measures Study and Corrective Measures Implementation Plan must be prepared and approved by EPA prior to proceeding with final remediation of the western parcel. Container Properties has been working closely with EPA in performing the interim actions that have been conducted at the site. It is generally understood by Container Properties and EPA that, assuming no further remedial construction is necessary at the site, industrial buildings could presently be constructed over contaminated areas provided that proper precautions are taken during construction and in the design of the buildings. Due to extent of contamination within the western parcel it is unlikely that feasible remedial actions would successfully attain cleanup levels throughout the parcel. However, it should be noted that site contamination presents a low risk to human health. While toluene and elevated pH groundwater are present at the site, the primary site contaminant is copper, which primarily affects aquatic life in the nearby Duwamish Waterway. The containment approach to site remediation that is already in place is compatible with development of industrial buildings and facilities on the parcel. Institutional controls restricting the site to industrial use and requiring appropriate safeguards for site construction and for preventing potential migration of vapors to the buildings would be required for future site redevelopment. The concerns expressed by the City are shared by EPA and by Container Properties. Container Properties is working with EPA to allow remediation of the western parcel in a way that will allow it to be redeveloped for industrial use, including construction of new buildings. Under the terms of the Order, EPA must review and approve all plans for remediation of the site. EPA is currently reviewing the redevelopment plan for the site to ensure that the development is consistent with the remediation objectives. Regarding the concern that potential wastes or other materials that may be present in underground structures or process piping, Container Properties is currently working closely with EPA to investigate and identify such materials. A formal work plan to sample and • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -4- January 4, 2006 characterize these materials in the areas of concern has been prepared and approved by EPA. Most of the characterization work has been completed; only characterization of above -grade process piping and vessels remains to be done. Of the work completed to date for this work plan, only one location (a sump) was found to contain materials remaining from site operations. After completing characterization of the materials found, they will be removed and disposed of properly. Process piping and vessel contents will be assessed in early January when properly trained contractors are available. If materials are found in piping or vessels, it will be characterized and removed. A formal report will be submitted to EPA to document this work so that demolition can proceed. After completion of this process, it is expected that EPA will approve the western parcel redevelopment plan that has been submitted for their approval. 6. It is our understanding that some minor areas of soil contamination exist on the eastern part of our site. Explain how and when these will be dealt with and identify the location of the contaminated areas. Response: A formal work plan has been prepared to address this contamination; EPA is presently reviewing the work plan. The work plan summarized available site characterization data for the eastern parcel and identifies areas where either additional data are needed to confirm contamination or proposes removal of contaminated soil. Confirmation sampling is included in the work plan to document attainment of Washington Department of Ecology cleanup levels for unrestricted land use. A copy of this work plan, which has not yet been approved by EPA, is attached. Container Properties is prepared to implement this work plan upon approval by EPA. The actual implementation schedule will depend on receipt of approval from EPA and the availability of environmental contractors to perform the removal actions included in the work plan. It is expected that EPA will approve removal of the eastern parcel from the Order after completing this work. Corrections to Plans: 7. Revise the plans to show the three groundwater recovery wells in addition to the monitoring wells. Response: The groundwater recovery wells have been called out on the enclosed site plans. Please refer to the Geomatrix Consultants, Inc. reports for status of all of the wells on site. 8. The plans must indicate where the existing groundwater pretreatment facility is located, as well as the proposed new location. In addition, both existing and proposed piping details must be provided on the plans. Response: The pretreatment system has already been relocated. The relocation work has nearly been completed — a new building was constructed to house the system and it was connected to power on January 3, 2006. All pretreatment equipment has been moved. It will be operated and maintained as it was before. The old building is now vacant and is being readied for demolition. 7 • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -5- January 4, 2006 9. The plans must indicate the current location of the on -site King County lift station and indicate whether it will also be relocated. Response: The old pretreatment system required use of a lift station. The new system does not use the lift station — the lift station has been bypassed. The old lift station will be demolished along with the rest of the site buildings. 10. It is unclear from review of the documents provided how the groundwater recovery wells, the groundwater pretreatment system piping, monitoring wells, and the upper surface of the slurry walls will be protected during grading and construction. Please explain, and if appropriate, provide revised drawings. Response: Please see the enclosed Western Parcel of Redevelopment Work Plan for a detailed description of the groundwater recovery well and pretreatment system decommissioning as well as the proposal for future groundwater monitoring and groundwater extraction wells that will remain. Specifically, please see Section 4.3.3, page 18 of the Western Parcel of Redevelopment Work Plan. SEPA Checklist: 11. Section B.1 .item f. The response to the question of whether erosion could occur as a result of clearing, construction, or use, does not make any sense. The slurry wall does nothing to protect sediment from leaving the site, as it is below ground and water constructed to intercept groundwater, not surface water. Response: It is unlikely that erosion could occur during clearing, construction, or use, provided that the temporary erosion and sedimentation control measures depicted on the enclosed TESC plans, as well as Section 4.2 of the Western Parcel of Redevelopment Work Plan, are followed closely. Silt fencing has been placed around the perimeter of the site and catch basin filters will be placed on every catch basin during site development. 12. Section B.7. items 1 and 2. The City should be provided with a copy of the EPA - approved Operation, Monitoring, Inspection, and Maintenance Plan referenced in the SEPA Checklist. Response: Enclosed are copies of the Western Parcel Redevelopment Work Plan as well as copies of the operation, monitoring, inspection, and maintenance plan as referenced in the SEPA checklist. Please note that neither of these plans have received EPA approval; however, both are under review by EPA at this time. 13. A detailed health and safety plan will be necessary for any grading /filling work on the site, including emergency measures and daily decontamination procedures. Please provide the City with a copy of the plan for the SEPA file when it has been prepared. Response: The Health and Safety Plan is included in the enclosed Western Parcel Redevelopment Work Plan prepared by Geomatrix dated November 2005. • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -6- January 4, 2006 Landscaping Plan 14. Since a variance is being requested from the King County shoreline requirement to place parking either under buildings or landward of the shoreline, please provide a schematic that shows how the landscaping adjacent to the shoreline will look one year after planting and three years after planting. Response: We have removed some of the parking between the proposed building and the shoreline and replaced it with landscaping. We can provide conceptual landscaping elevations (if necessary) once the landscaping plans have been generally accepted by the City. 15. Please enlarge the portion of the proposed landscaping for the streetscape and the front of the building — it is difficult to identify all the plants that are proposed for these locations. Response: Enclosed is a 1 " =20' enlargement of the eastern side of the building as well as the landscaping fronting East Marginal Way South for your review. Please note that this is a blowup of just a portion of the preliminary Landscaping Planting Plan, which is provided entirely as Sheet L1 of 2 in the plan set. 16. Please confirm the location of the Cornus Kousa — are these trees proposed along the front of the building? Response: We have altered the symbol for the Cornus Kousa so that they are more visible along the east side of the building. 17. 1 only count 16 Thuja Plicata 'Excelsa.' Response: We have verified the correct count (20) of Thuja Plicata 'Excelsa' in the Landscape Planting Material Legend on Sheet L1 of 2. 18. The common name of Pennisetum Alopecuroides 'Hameln' is listed as Oregon Grape, which is incorrect. Please correct the table. Response: The common name for Pennisetum Alopecuroides 'Hameln' has been corrected. 19. Landscaping is required to screen the proposed storage yard from the shoreline. Response: Existing vegetation surrounding the property along the shoreline will screen the proposed storage yard. Disruption of this existing vegetation to replant with landscaping materials may be more deleterious than keeping the existing vegetation in place. Public Works Comments: 20. Please refer to the Pre - application Meeting comments from Public Works. A copy is included. A number of the items on the Public Works comment sheet were not included or i • • Carol Lumb, Senior Planner City of Tukwila Department of Community Development -7- January 4, 2006 addressed in the submittal materials. Please provide the missing items that are highlighted on the enclosed Checklist. Response: Enclosed is a Traffic Impact Analysis prepared by the Transpo Group dated December 2005. Also enclosed is the Boundary and Topographic Survey, which identifies existing easements on the site. Finally, enclosed is documentation regarding ownership for Parcel 542260 -0015, which indicates access and utility rights to the subject property (please see enclosed Warranty Deed, recording no. 4781818) exist over the BNSF property. 21. Provide a Traffic Impact Analysis prepared by an engineer licensed in Washington State that includes analysis of turning movements at the existing signalized access and at the proposed additional access. The site plan can not be evaluated properly without knowing what traffic impacts need mitigation. Response: Please see the enclosed Traffic Impact Analysis. 22. Please provide civil sheet(s) that include: a. All existing easements that will remain after the demolition and all new easements, including access across BNSF property. Response: The civil sheets have been revised to identify easements that will remain as well as new easements after project development. Access rights across the BNSF property are established by the enclosed Warranty Deed recording no. 4784818 provision [1], which states: "the Grantor expressly reserves to itself, its successors or assigns, the right for its servants and agents, and any other person or persons acting for the benefit, or on behalf, of Grantor, its successors or assigns to cross the strip or parcel of land hereby conveyed at such place or places and at such time or times as the Grantor, it successors or assigns, may desire, and the Grantor further expressly reserves to itself, its successors or assigns, the right to cross said strip or parcel of land at any time with electric, water, gas, telephone, or other utility service lines, entrances or exits in a manner which will not obstruct the railroad uses of said strip or parcel of land; ". b. Plans that indicate what will remain after all of the demolition and removal of pipes, catch basins, etc. The plans provided include all of the existing sewer, water, and storm drainage elements, making it difficult to sort out what will remain. Please note that the demolition notes do not correlate to the utility locations on the drawings, so it is difficult to tell what will be removed as part of the demolition. (see Sheet E2 for example) Response: We have revised civil and demolition sheets to make it more clear what will remain and what will be removed during project development. • o Carol Lumb, Senior Planner City of Tukwila Department of Community Development -8- January 4, 2006 c. Any measures needed to alleviate or improve turning movement conflicts at the accesses points. Response: As indicated in the Traffic Impact Analysis prepared by the Transpo Group dated December 2005, the intersection of South 92nd Place and East Marginal Way South has a split phased green signal such that turning movements for the subject property and the property to the north do not conflict with each other. Under existing conditions, the intersection of South 92nd Place and East Marginal Way South operates at LOS A. d. Rerouting of the 36" storm drain. (Refer to the Technical Information Report) Response: The rerouted storm drain is depicted on the site plans. 23. Provide approval from BNSF to cross property for access. Response: As indicated on the enclosed Easement Recording No. 4781818, additional approval from BNSF to cross property for access is not necessary as a reservation for access and utilities is part of the legal description for the BNSF property. We believe that the above responses, together with the enclosed revised plan and technical documents, address all of the comments in your letters dated September 14, 2005, and October 27, 2005.

In April 2003, a significant interim action was undertaken at the site. The interim measure was conducted as a RCRA corrective action under Administrative Order on Consent No. 1091- 11- 20- 3008(h) (Order) between Container Properties, L.L.C. (Container Properties); Rhodia, Inc.; and the U.S. Environmental Protection Agency, Region 10 (EPA), dated March 31, 1993, as amended in February 1999. The interim measure was completed m accordance with the Interim Measure Construction Work Plan (IMCWP) approved by EPA (URS, 2002). Container Properties has recently decided to proceed with redevelopment of the former Rhone - Poulenc site, which will require demolition of existing above - ground structures on the property. This redevelopment work will not adversely affect the recently completed interim measure. However, it will be necessary to relocate the groundwater pretreatment system as a part of redevelopment. Since the pretreatment system is a major component of the interim measure, this amendment to the IMCWP has been prepared to document plans for relocating the pretreatment system. This work plan amendment is being submitted to EPA for approval prior to relocating the groundwater pretreatment system. 1.1 BACKGROUND The site occupies about 21 acres in the City of Tukwila in an area known as Seattle's South End Industrial District. Industrial use of the site began in the 1930s when I.F. Laucks built a pilot plant to formulate glue for use in plywood manufacturing. In 1949, Monsanto Chemical Company (Monsanto) purchased the site and continued the manufacture of glue, as well as paints, resins, and storage of wood preservatives. Monsanto began vanillin production in 1952 which continued through sale of the property to Rhone- Poulenc in 1985. Rhone- Poulenc closed the site permanently in April 1991 and transferred the title of the property to Rhodia, Inc. in January 1998. Rhodia sold the property on November 1998 to Container Properties L.L.C., the current owner. J:18769.000 RCI R- PW36\Pretreat Relocate Packige ver•03 atcdac 1 GEOMATRIX Since site closure in 1991, extensive investigations have been completed to evaluate environmental impacts to soil and groundwater from the former vanillin plant. The investigations have followed the RCRA process from an initial RCRA Facility Assessment (RFA) through the RCRA Facility Investigation (RFI). Studies completed subsequent to the RFI include geoprobe and geotechnical investigations conducted in support of interim measure design. Quarterly monitoring of groundwater is conducted at the site; the Round 25 Quarterly Monitoring Report has been submitted to EPA. The current property owner, Container Properties, moved forward with an interim action on the site to control the potential for contaminants from the site to migrate toward the Duwamish Waterway. Container Properties completed construction of this interim action in April 2003 per the IMCWP. The interim measure consisted of the installation of a subsurface low - permeability barrier wall surrounding, to the maximum extent practicable, the environmentally impacted portion of the site. The area surrounded by the barrier wall corresponds to roughly the western half of the site (Figure 1). Along with the barrier wall, the interim measure includes a system of groundwater extraction wells and a pretreatment system to pump groundwater from inside the contained area, thereby creating an inward groundwater gradient. The pretreated groundwater is discharged to a publicly owned treatment works, owned and operated by King County, and permitted under the Clean Water Act. A system of monitoring wells inside and outside the barrier wall is monitored per the June 3, 2003 Interim Measures Performance Monitoring Plan (PMP) to ensure the interim measure maintains an appropriate inward hydraulic gradient (Geomatrix, 2003). The interim measure hydraulic control performance standard is to maintain an inward hydraulic gradient between 72 -hour average water levels measured in Wells DM -8 (outside) and MW-49 (inside). The groundwater pretreatment system is presently located within an existing site building. Container Properties has decided to proceed with redevelopment of the former Rhone - Poulenc site. Final, long -term redevelopment plans have not yet been finalized for the site; however, plans for initial redevelopment have been sufficiently developed to support construction of limited facilities for the site. The overall goal of site redevelopment is to return the site to productive use so that it may contribute to the local economy. The site has been dormant for more than 13 years. Container Properties is presently negotiating with several parties regarding potential reuse of the site. These negotiations have developed with sufficient certainty to support commitment of resources to site redevelopment. The approach for site redevelopment has been designed to be compatible with the ongoing environmental management activities for JA8769.000 RCI R- P\026Trettcat Relocate P ckagc-vcr -03 als.doc • a GEOMATRIX • 0 the site, including operations and maintenance for the hydraulic control interim measure, the corrective measure study, and monitoring programs. As part of the redevelopment, it will be necessary to demolish existing above -grade structures present at the former Rhone- Poulenc site. Due to the demolition it will also be necessary to relocate the groundwater collection piping and groundwater pretreatment system associated with the hydraulic control interim measure, since this unit is presently housed in one of the existing site buildings that is scheduled to be demolished as part of site redevelopment. The plans, specifications and implementation schedule for relocation of the groundwater pretreatment system are included in this work plan amendment. 1.2 PURPOSE In support of the redevelopment of the former Rhone- Poulenc site, the existing groundwater pretreatment system will be relocated to a new building. The purpose of this relocation work plan amendment is to document the details regarding the change to the hydraulic control interim measure being implemented at the site. This plan includes sufficient detail to demonstrate that the relocated system will continue to provide the pumping, control, and pretreatment capability needed to attain and maintain interim measure performance objectives and standards. Since the groundwater pretreatment system is an integral element of the hydraulic control interim measure, these plans and specifications are being submitted to the EPA, Region 10, for review and approval. The relocation work plan amendment will be implemented after receiving EPA approval. 1.3 PRETREATMENT SYSTEM RELOCATION PROJECT SCOPE The groundwater pretreatment system is an integral part of the hydraulic control interim measure. Continued operation of the pretreatment system is critical to attainment of interim measure performance standards and objectives. The relocation project has been designed to ensure that the pretreatment system will continue to perform as required so that the interim measure will continue to attain performance standards. The scope of the pretreatment system relocation project includes the following elements: • Construction of a new, dedicated building to house the pretreatment system; • Replacement/rerouting of well discharge lines to the new pretreatment building; J:48769.000 RCI R -P026W ctroat Rolocato Package -qtr -03 als.doc 3 GEOMATRIX • s • Replacement/rerouting of communication and control lines from MW-49, DM -8, and the three extraction wells (EX -1, EX -2, and EX -3) to the new pretreatment building; • Replacement/rerouting of the discharge line from the new pretreatment building to the existing wastewater lift station; and • Replacement/rerouting of an instrument line from the existing wastewater lift station to the new pretreatment building. To the extent possible, the existing pretreatment system and supporting piping, equipment, and controls will not be modified; the original plans and specifications will apply to the relocated system and they will be referenced in this IMCWP amendment as appropriate. The plans, drawings, and specifications included in and/or referenced by this amendment describe any changes to the system and provide sufficient detail to ensure that the relocated system will continue to perform as needed to achieve interim measure standards and objectives. Additional work will be conducted at the former Rhone- Poulenc site as part of site redevelopment. This additional work is described in this amendment, but it is not considered part of the scope of the pretreatment system relocation work plan amendment and is not covered by the terms of the Order. This additional work includes the following: • Demolition of facility structures necessary to conduct the planned redevelopment; • Filling, grading, and paving the site to promote runoff and manage stormwater, • Replacement of mechanical equipment for the wastewater lift station; • Modification/improvement to site security fencing; and • Permitting to support the redevelopment work described above. The additional site redevelopment work will be completed after relocation of the groundwater pretreatment system. This additional work is described generally in this work plan amendment to provide a comprehensive overview of the work to be completed at the site. Additional details regarding the site redevelopment work will be provided to EPA for information purposes as plans are sufficiently developed. 2.0 REDEVELOPMENT PLAN Container Properties is preparing for redevelopment of the former Rhone- Poulenc site, with continuing industrial use of the property. Negotiations are underway with potential tenants for J:18769.000 RCI R- P10261Prctreat Relocate Paclagc- vcr-03 als.doc 4 GEOMATRIX • • the western portion of the former Rhone- Poulenc site. Based on the current status of these negotiations and the similarities for use of the site, Container Properties has decided to proceed with initial redevelopment of the western portion of the site. Preliminary plans are also being prepared for potential redevelopment of the entire former Rhone- Poulenc site. However, long- term redevelopment plans have not been sufficiently developed to commence implementation at this time. Long -term development plans will be presented after they have been more firmly established. The western portion of the site will be redeveloped for surface storage. In support of this use, initial site redevelopment will include demolition of surface structures present at the site, grading and paving of the western portion, construction of permanent fencing surrounding the western portion of the site, and construction of stormwater control facilities. Initial redevelopment of the former Rhone- Poulenc site will be limited to the western portion of the site. Redevelopment of this portion of the site will be directed toward making the area suitable for surface storage materials such as trucks, passenger vehicles, and/or shipping containers. The area to be addressed for initial redevelopment is shown in Figure 1. The scope of the initial redevelopment includes demolition of above -grade structures, relocation of the groundwater pretreatment system and piping, filling and grading to control surface water runoff, and repaving the area with asphalt. Specific details of the redevelopment should be finalized by February 2005; however, since demolition is required for all redevelopment alternatives under consideration, demolition and the initial site redevelopment plan will proceed as soon as possible. Completing the demolition in early spring will allow site use by early summer 2005. Although only the western area shown in Figure 1 will be redeveloped initially, all above -grade structures present at the former Rhone- Poulenc site will be demolished at the same time. Prior to demolishing the large building in the westem portion of the site, the groundwater pretreatment system will be relocated so that the hydraulic control interim measure will continue to operate and maintain an inward hydraulic gradient. Existing above grade structures, including all existing buildings, the electrical substation, and the stormwater tank will be demolished and removed from the site. The existing wastewater lift station will remain at its present location and the structure will remain intact. Surficial portions of foundations will be removed as needed to support grading and paving of the area. Existing subgrade basement structures and low areas will be filled with clean fill prior to grading. A layer of asphalt concrete will be placed over the initial development area (see Figure 1). 1A8769.000 RCI R- PW26\Prctrcat Rclocarc Package-vet-03 als.1oc 5 GEOMATRIX • 0 As part of the initial redevelopment of the site, stormwater management facilities will be designed and installed to comply with the City of Tukwila stormwater management requirements. Plans and permit applications for stormwater management are being developed but have not been finalized. Runoff from the initial development area will be directed to the northeast corner of the initial development area where stormwater retention facilities will be constructed. Stormwater will drain from the retention facilities through an existing outfall. The stormwater management system will be designed to comply with Tukwila and Ecology regulatory requirements and will be operated under a stormwater discharge permit. Copies of the redevelopment plans will be sent to EPA when they are finalized. 3.0 PRETREATMENT SYSTEM RELOCATION PLAN The groundwater pretreatment system presently located in the existing building in the western portion of the site will be relocated to a new building built to house the pretreatment system and controls. The existing building housing the pretreatment system will be demolished as part of site redevelopment. The new pretreatment building will be located along the northern property line, as shown on Drawing 1, Appendix A. Relocation of the pretreatment system will also require relocation of piping and power /communications wiring for the extraction wells and the wastewater lift station. The approximate locations for new piping, power lines, and communications lines from the three extraction wells to the new building and from the new building to the lift station are shown in Appendix A, Drawing 1. Final locations for piping and conduit will be determined in the field. The existing process configuration, process controls, and process control approach will not be changed for the relocated pretreatment system. Construction for relocation of the pretreatment system will be performed to minimize the period of time the system must be shut down to complete the move. Based on observed groundwater levels during the time the interim measure groundwater recovery system has been in operation, proper planning will ensure that an inward hydraulic gradient meeting the hydraulic control performance standard can be maintained during the time the pretreatment system is shut down and moved to the new building. Prior to shut down of the system for relocation, groundwater pumping rates will be increased to depress the water table inside the barrier wall and establish a hydraulic gradient greater than required by the hydraulic control performance standard. The depressed groundwater level would allow short-term shutdown of the groundwater recovery system during relocation while maintaining an inward hydraulic gradient. Transducer readings in Wells DM -8 and MW -49 will be digitally recorded by a portable, battery- operated data logger during the relocation of the J:18769.000 RCI R- PO261Prctrcat Relocate Packigc- ver.03 alsdoc 6 GEOMATRIX • . pretreatment system to ensure a continuous record of groundwater levels is maintained. Details for the pretreatment system relocation are presented in the following subsections. Plans and specifications for relocating the pretreatment system include those presented in Appendices A and B of this work plan amendment and those included in the final Interim Measures Construction Work Plan (IMCWP) dated October 25, 2002 (URS, 2002). If the plans or specifications presented in the IMCWP differ from those presented in this relocation plan, the plans and specifications presented in this plan shall apply. 3.1 GROUNDWATER COLLECTION AND DISCHARGE PIPING Groundwater pumped from Wells EX -1, EX -2, and EX -3 will be conveyed to the pretreatment system in the same manner as is done with the existing system. Conveyance piping will be run from the individual extraction wells to the pretreatment building using underground piping at the approximate locations shown in Appendix A, Drawing 1. Underground piping will be 2- inch diameter Schedule 80 PVC, as was used for the existing system. A single line will be run from each well to the pretreatment building. The approximate locations for the piping from the wells to the new pretreatment building are shown on Drawing 1 (Appendix A). Final piping locations will be determined in the field during installation, and may be modified from those shown on Drawing 1 due to underground structures or utilities. Specifications and details for the groundwater collection piping and trenching are included in the IMCWP and as included in Appendix A of this relocation plan. As noted in these plans, all underground piping for untreated groundwater will be located inside the existing subsurface barrier wall. A single 2 -inch Schedule 80 PVC line will be installed to transfer the pretreated groundwater to the lift station. The approximate location of the line is shown on Drawing 1, Appendix A; the final location for this line will be determined in the field during installation. This line will be installed in accordance with the plans and specifications included in the final IMCWP and presented in Appendix A of this plan. 3.2 GROUNDWATER PRETREATMENT SYSTEM AND BUILDING A new building will be constructed to house the groundwater pretreatment system and controls. The approximate location for the building is shown on Drawing 1, Appendix A. The building will be prefabricated and will be mounted over a concrete slab. The existing groundwater pretreatment equipment, including the carbon adsorption units, flow meters, filters, tanks, and all controls presently installed in the existing site building will be moved into the new pretreatment building. Plans and specifications for the new building and the relocated 1:18769.000 RCI R- PW361Ptetreat Relocate Package- vcr-03 alsdoc 7 OEOMATRIX • 0 pretreatment system are included in Appendices A and B of this relocation plan and in the final IMCWP. The pretreatment building will be located in the approximate location shown on Drawing 1, Appendix A. As shown, the building will be placed near the north property line and the building will be located directly above the barrier wall. Piping will enter the south wall of the building, as shown on Drawing 2, Appendix A. The south wall of the building will be located inside the barrier wall so that underground piping containing untreated groundwater will be entirely inside the barrier wall. The floor of the building will be a concrete slab entirely surrounded by a six -inch high curb to provide secondary containment in the event of a spill or leak in the pretreatment system. Untreated groundwater piping will enter the south wall of the building, with the piping entering the building above the curbing (see Drawing 2, Appendix A). Inside the building, piping will be placed in a shallow trough running down the central portion of the building, with grating covering the pipe trough. Treated groundwater will exit the building through the south wall to direct the treated water to the lift station. The pipe trough will also provide drainage inside the building, with the trough sloped to a collection sump and the flow sloped toward the trough. An overhead door will provide access to service the carbon adsorption units. The building will be equipped with a heating system to maintain the building above freezing temperatures during the winter. The pretreatment building will include ventilation to ensure that volatile hydrocarbons do not accumulate within the building. Ventilation will include passive vents within the roof and along the base of the building as well as an active ventilation fan that will be activated whenever personnel enter the building. The groundwater recovery and pretreatment system will be controlled and operated in accordance with the final IMCWP approved by EPA. The revised process and instrumentation diagram is included as Drawing 3 in Appendix A. The pretreatment process is essentially the same as included in the IMCWP; however, the capacity of the system has been increased from a maximum capacity of 10 gallons per minute (gpm) to a maximum capacity of 45 gpm, the surge tank included in the original design has been eliminated because it was found to be unnecessary, and a purge /sump tank has been added to allow purge water from sampling monitoring wells to be treated and discharged to the lift station. The existing programmable logic controller (PLC) and data recorder will continue to monitor, control, and record groundwater levels in wells DM -8 and MW -49, as is being done presently and as specified in the IMCWP. A telephone line will be run to the new building to provide remote access to the PLC via a modem and to allow the autodialer to contact operations staff in the event of an alarm condition. Spills within the pretreatment building will be detected by a level switch 1;18769.000 RCI R- P10261Pretreat Relocate Package- vcr-03 als.doc 8 GEOMATRIX • • installed in the building collection sump: if a spill occurs, the sump level switch will initiate a complete shutdown of the recovery and pretreatment system and the PLC will contact operations staff to report the alarm condition. A high water level switch installed in the lift station will also initiate a complete recovery system shutdown and autodialer report. All other aspects of the recovery, pretreatment, and control systems will be unchanged from the present system. Specifications for the equipment in the expanded pretreatment system are included in Appendix B of this relocation plan. The electrical system for the relocated pretreatment system will be the same as for the original system; relevant electrical drawings and specifications included in the IMCWP will be used for the relocated pretreatment system. 3.3 LIFT STATION The wastewater lift station will continue to be used to transfer treated groundwater to the King County Department of Natural Resources publicly owned treatment system for final treatment and discharge. The lift station will be used in the same manner as it is presently used and as described in the IMCWP. As noted above, a level switch has been installed in the lift station to detect failure of the lift station and to shut down the groundwater recovery and pretreatment system in the event of high water in the lift station. This high level cutoff is designed to minimize the potential for causing an overflow from the lift station. 3.4 RELOCATION PLAN A plan for relocation of the pretreatment system has been developed that will complete the work in a manner that maintains compliance with the one -foot inward hydraulic gradient specified in the approved IMCWP. The sequence of the work will be as follows: 1. Increase the groundwater recovery rate in the existing system to decrease the groundwater level inside the wall so that the extraction wells could be shut down and an inward hydraulic gradient would be maintained during relocation of the pretreatment system. 2. Obtain equipment and materials necessary to relocate the pretreatment system (prefabricated building, piping, etc.) and commence installation per the plans and specifications included or referenced in this document. 3. Install power to the new pretreatment building. 1:,8769.000 RCI R- P‘026Wretreat Relocate Package- ver-03 als.Joc 9 GEOMATRIX • • 4. Prepare a detailed plan to complete the pretreatment system relocation and ensure that adequate resources, including labor and materials, are readily available to complete the relocation in a timely manner. 5. Obtain a two- channel (or greater) battery operated data logger for the transducers installed in MW-49 and DM -8. 6. Place the groundwater recovery and pretreatment system in continuous, manual operation. Disconnect the transducer cables from Wells MW -49 and DM -8 and immediately connect the transducers to the portable data logger. 7. Shut down the groundwater recovery and pretreatment system. Flush the pretreatment system with clean, potable water and drain lines and equipment as appropriate. 8. Remove pretreatment system controls and equipment from the existing building and reinstall it in the new pretreatment building per the plans and specifications included or referenced in this document. 9. Connect piping and electricallcommunication lines from the extraction wells to the new lines leading to the new pretreatment building and the piping and electrical/communication lines from the new building to the lift station. 10. Check relocated and new equipment and controls for proper operation. 11. Disconnect the temporary data logger and connect the transducers in Wells MW -49 and DM -8 to the PLC. Commission the relocated recovery and pretreatment system. 12. Commence normal operation of the relocated pretreatment system. It is expected that the groundwater recovery and pretreatment system must be shut down for a minimum of one week to complete the relocation and startup work. If complications are encountered, the shutdown may extend beyond one week. In order to ensure that an inward hydraulic gradient will be maintained throughout the shutdown period, the groundwater level inside the barrier wall will be lowered prior to shutdown to provide an inward hydraulic gradient of at least 2.5 feet (based on the 72 -hour average water levels measured in Wells DM -8 and MW -49). Based on observed recovery rates at the site, it is expected that this will maintain compliance with the specified inward gradient of 1 foot during the week long relocation and would maintain an inward gradient for more than one week. However, it is possible that the inward gradient may temporarily become less than 1 foot during relocation work. 1:18769.000 RCl R- P1026tPretrcat Relocate Packagc -vcr -03 aLsdoc GEOMATRIX 10 • • The 72 -hour average water levels in the two control wells (MW-49 and DM -8) will be monitored daily during relocation using the portable data logger. If water level monitoring data indicate that groundwater levels inside the barrier wall are recovering faster than expected relative to water levels outside the wall and that an inward gradient is not likely to be present prior to completing relocation work, Container Properties will report the situation to EPA and initiate action as appropriate to commence groundwater recovery as soon as possible. The actions taken to commence groundwater recovery may include installing temporary lines to allow pumping and pretreatment, installing temporary treatment equipment, working with King County to obtain necessary approvals prior to pumping, and/or installation of temporary water storage capacity. Based on the interim measure operation experience to date, it is unlikely that emergency pumping will be necessary to maintain an inward hydraulic gradient. 4.0 GROUNDWATER PRETREATMENT SYSTEM OPERATION, MAINTENANCE, AND INSPECTION The Operation, Monitoring, Inspection, and Maintenance Plan (O &M Plan) has been revised as appropriate based on the relocated pretreatment system. The revised O &M Plan is included as Appendix C to this relocation plan. In general, groundwater pretreatment system will be operated, maintained, and inspected in the same manner as was done under the March 2004 O &M Plan previously submitted to EPA. The revised O &M Plan incorporates the expanded recovery and treatment capacity of the pretreatment system, replacement of the surge tank with the purge/sump station, and placement of the system in the new pretreatment building. Operation of the groundwater recovery system will be done in accordance with the attached revised O &M Plan after relocation of the system to the new building. The revised process and instrumentation diagram for the groundwater recovery system is included as Drawing 3, Appendix A. As shown by the flow diagram, most of the pretreatment process is identical to the process included in the final IMCWP, However, the capacity of the pretreatment system has been increased from 10 gpm to 45 gpm. In addition, the surge tank included in the original process design has been eliminated. The submersible groundwater extraction pumps have sufficient capacity to pump groundwater through the filters, the carbon adsorption units, and then to the lift station. The system has been operated in this manner for several months. A purge/sump station has been added to the pretreatment system. This station is a rectangular open -top tank that can be used to pump purge water or spills collected from the containment area through the pretreatment system and to the lift station. The purge /sump station is also used to pump purge water from groundwater sampling through the pretreatment system. As shown on Drawing 3, water pumped from the purge /sump station passes through 1:18769.000 RCI R- P10261Pretreat Relocate Package vcr•03 als.doc GEQMATRIX 11 the filter and the carbon units before discharge to the lift station. Water is not stored in the purge/sump station; whenever water is placed in the purge /sump station, it is subsequently pumped through the pretreatment system by manually activating the transfer pump. 5.0 REFERENCES Geomatnx Consultants, Inc., 2003, Intenm Measures Performance Monitonng Plan, Former Rhone - Poulenc Site.

Container Properties, LLC, the owner of the property, has submitted a request to the City of Tukwila to subdivide the former Rhone- Poulenc site into two separate parcels, as shown on Figure 2. The western parcel encompasses the area addressed by the hydraulic control interim measure (HCIM) which includes the barrier wall and the groundwater recovery and pretreatment system. The eastern parcel encompasses the area that was not extensively used for processing and is not heavily contaminated. This Redevelopment Work Plan addresses redevelopment activities planned for the western parcel only. A separate redevelopment plan may be prepared for the eastern parcel. Container Properties has recently issued a 15 -year lease for the western parcel to Insurance Auto Auctions Inc. (IAAI), who currently leases the former Paccar property immediately north of the Site for storing and auctioning used cars and trucks. IAAI will use the western parcel in the same manner as their present operations at the former Paccar property. Davis Property and Investment, LLC (Davis Properties) is managing redevelopment of the western parcel on behalf of Container Properties. The planned redevelopment will require an extensive amount of work to prepare the western parcel for the IAAI lease. Preparatory work will include demolition of existing structures, installation of new electrical service, and relocation of the groundwater recovery and pretreatment system being operated as part of the HCIM. These preparatory activities have been described in separate work plans and are not included in the scope of this Redevelopment Work Plan. The preparatory work covered by previously submitted plans is only described in general terms where the work is relevant to this Redevelopment Work Plan. This work plan presents the proposed activities and design to redevelop the western parcel to meet the provisions of the lease agreement with IAAI. Development activities will include installation of a new stormwater collection and management system, regrading, paving, and construction of a permanent fence along the western parcel boundaries. Western Parcel development is planned to be completed during the first quarter of 2006. Container Properties is submitting 1 Geomatrix this Redevelopment Work Plan to the U.S. Environmental Protection Agency (EPA) for review and approval, prior to performing this work. Separate submittals have been made to the City of Tukwila and other agencies for review and permitting to support this redevelopment. 1.1 SITE BACKGROUND The Site occupies about 21 acres in the City of Tukwila in an area known as Seattle's South End Industrial District. This property has been under industrial use since the 1930s. Most recently, Rhone- Poulenc operated a vanillin manufacturing facility that was closed in 1991. Historic releases of hazardous substances occurred at the Site. Released constituents include caustic soda, toluene, mineral oil, PCBs, and copper. Corrective action for the historic releases is being addressed under a Resource Conservation and Recovery Act (RCRA) Administrative Order on Consent (Order), Docket No. 1091- 11- 20- 3008(h) issued by the U.S. Environmental Protection Agency (EPA), Region 10. Container Properties has primary responsibility for implementing the provisions of the Order. The Site is being subdivided into two parcels. The western parcel, consisting of about 13.15 acres, is being redeveloped as described in this plan. The eastern parcel, consisting of about 6.47 acres, is not addressed by this plan. The remaining portion of the Site consists of the shoreline and submerged lands. A copy of the short plat drawings filed with the City of Tukwila is included as Appendix A. 1.3 PURPOSE AND SCOPE The purpose of this Redevelopment Work Plan is to document the work planned to complete redevelopment of the western parcel. The area to be redeveloped is shown on Figure 2. Redevelopment will include the following: • Abandonment of unnecessary groundwater monitoring wells and vapor extraction wells; • Installation of new stormwater collection, treatment, and discharge system; • Site Grading; and • Paving the western area with asphalt. Details concerning the above project scope are described in this Redevelopment Work Plan. New security for the western parcel will be installed by IAAI after the above redevelopment work is complete. After installation of the new security fencing by IAAI, security will be provided by IAAI and access to the area will be through the IAAI facility. The lease includes J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 2 provisions to ensure that the HCIM facilities and monitoring wells can be freely accessed after control of western parcel is assumed by IAAI. J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix 3 2.0 PERMITTING This section describes potential permits and related administrative requirements for the redevelopment work. The permits identified in this section are potentially required to complete the redevelopment work. Davis Properties and Geomatrix, on behalf of Container Properties, will obtain required permits and approvals under applicable laws /regulations, including the Revised Code of Washington (RCW), the Washington Administrative Code (WAC), and the Tukwila Municipal Code (TMC). Notifications and administrative requirements will be performed in a timely manner prior to construction. The known or potential permits identified to date are as follows: • State Environmental Policy Act (SEPA) environmental review (43.21C RCW, coordinated under the City of Tukwila's SEPA Planned Action application) • .Shoreline Permit (TMC 18.44) • Hauling permit and land altering permit (City of Tukwila) • Construction Stormwater General Permit (Ecology) • Well construction/abandonment (start card) notification (WAC 173 -160) • Puget Sound Clean Air Agency (PSCAA) Notice of Construction J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix During permitting activities, Davis Properties or Geomatrix may determine that some of these permits are not necessary, or may identify and acquire other construction permits necessary to perform the work. Ongoing discussions between Davis Properties or Geomatrix and the regulating agencies will determine the actual permits, notices, and reporting requirements for this project. 2.1 LOCAL REQUIREMENTS The City of Tukwila coordinates the SEPA and shoreline permitting for grading and paving projects. Davis Properties has submitted the SEPA and shoreline permitting packages to the City of Tukwila. These packages are presently under review and are expected to be finalized by late winter. Copies of the SEPA and shoreline permitting submittals are included as Appendix B. No other local permitting requirements are anticipated for the planned redevelopment work. 4 Geomatrix The PSCAA is a local agency that regulates air quality within the Puget Sound Area under the Clean Air Act. In accordance with PSCAA requirements, Davis Properties will issue a Notice of Construction to PSCAA prior to commencement of construction. Measures will be implemented during construction to limit the emission of dust. No other significant emission sources are anticipated during the redevelopment work. 2.2 STATE REQUIREMENTS State permitting requirements include SEPA, shoreline, and stormwater permits. The state SEPA and shoreline requirements for this project have been delegated to the City of Tukwila, and will be addressed as described above under local regulatory requirements. Ecology also has been delegated authority for issuing stormwater discharge permits under the federal Clean Water Act. This includes oversight and permitting for construction- related activities. Ecology has issued a general stormwater permit for the Site to Davis Properties. Stormwater management and temporary erosion and sediment control (TESC) must comply with the State of Washington's Stormwater Management Manual for Western Washington (Ecology, 2001). The State of Washington's water quality regulations include WAC 173 -200, Water Quality Standards for Ground Waters of the State of Washington; WAC 173 -201A, Water Quality Standards for Surface Waters of the State of Washington; and WAC 173 -204, Sediment Management Standards. Stormwater runoff and erosion control will be managed in accordance with the general stormwater permit and as discussed in Section 4.2.1. 2.3 FEDERAL REQUIREMENTS The redevelopment work will include trenching to install the stormwater system, grading, and paving of the western parcel. Based on the scope of work, the contractors are not expected to store oil or fuel in large enough volumes to require a Spill Prevention and Containment Plan as required under the Federal Water Pollution Control Act. Equipment will be fueled as needed by a fueling truck; no fuel will be stored onsite during construction. Ecology has been delegated authority for regulation of stormwater runoff; these regulatory requirements will be addressed as described above under state regulatory requirements. The work will be performed in accordance with RCRA requirements; however, no RCRA permit is needed for the redevelopment work. A biological assessment was completed for the Site as part of the HCIM construction. This assessment determined that the HCIM construction, which was much more extensive than the work that will be done under this Redevelopment Work Plan, would not adversely affect J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 5 Geomatrix endangered species provided that the work was completed prior to annual migration of salmonids in the Duwamish Waterway (prior to March). The limited construction to be done under this Redevelopment Work Plan is not expected to have significant potential for impacting aquatic biota. Stormwater and erosion will be managed in accordance with the Ecology general stormwater permit. The potential for affecting endangered species will be assessed under the SEPA program administered by the City of Tukwila. 2.4 DURATION OF PERMITTING ACTIVITIES The estimated duration for specific permitting or administrative activities are indicated below: • SEPA Planned Action review, 3 to 6 months • Shoreline Permit, 3 to 6 months • Land Altering Permit, hauling permit, and temporary water meter permit, 1 month • PSCAA Notice of Construction, 1 month As noted previously, the SEPA and shoreline permitting packages have been submitted to the City of Tukwila and they are presently under review. It is expected that the necessary permits will be issued by the City of Tukwila very early in 2006. J: \8769.000 RCI R- P\060 \RP -Site Develop WP- ver- 03.doc 6 3.0 SITE REDEVELOPMENT PLAN J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix Redevelopment activities will be limited to work needed to prepare the western parcel for use by the lessee, IAAI. This work will include the following: • abandonment of unneeded monitoring and vapor recovery wells as approved by EPA; • installation of a new stormwater collection and treatment system; • grading of the site to improve drainage; and • placement of asphalt cover over the entire western parcel. Placement of the asphalt cover will complete the work covered by this Redevelopment Work Plan. 3.1 WELL ABANDONMENT Numerous wells have been installed at the Site during site characterization and as part of the interim remedial measures that have been implemented. While some of these wells are being used for monitoring or remediation purposes, a number are no longer used. Wells represent a potential flow path for surface spills to enter groundwater. Welts can become damaged from surface activities, particularly uses that involve heavy equipment. As such, the Site wells represent a potential risk to the environment, particularly after redevelopment is completed and the Site is returned to regular use. As noted above, the surface elevation in the western parcel will be increased as part of redevelopment. Therefore, it will be necessary to extend the casing and modify the existing surface completion for each monitoring well that will remain within this area. There is also significant potential for causing damage to the wells during excavation for stormwater system installation and during fill and grading work. It is proposed all existing wells that are not required for long -term monitoring of the HCIM be abandoned prior to filling and grading. Based on available records and field inspections, all existing wells at the Site are summarized on Table 1. A total of 76 monitoring wells have been installed to characterize the nature and extent of affected groundwater and four additional wells were installed for the soil vapor extraction (SVE) interim measure, for a total of 80 wells. Of these wells, 35 are monitored either quarterly or monthly as part of the performance monitoring program. The four SVE wells are no longer being used for any purpose. Three extraction wells were installed as part of the HCIM and are presently being pumped to maintain an inward hydraulic gradient. 7 The rationale for abandonment of these wells is as follows: :: Geomatrix Additionally, four monitoring wells located inside the barrier are periodically monitored for water level to prepare groundwater contours within the contained area. A total of 40 of the existing wells are not being used for any purpose. EPA is presently reviewing the November 30, 2004 request to reduce the scope and frequency of performance monitoring at the Site. It is expected that the scope of the monitoring program may be further reduced, which would remove additional wells from service; however, the potential reduction in active monitoring wells is not yet known. Container Properties proposes that the unused monitoring and SVE wells be abandoned by a licensed driller in accordance with the Washington State Department of Ecology well abandonment procedures. The specific wells proposed for abandonment are listed in Table 1 and shown on Figure 2. Only wells not being used for monitoring or to support the active HCIM are currently proposed for abandonment. The 40 wells proposed for abandonment include only one well (Well MW -36) that is located downgradient from the barrier wall. Well MW -36 is located in the berm along the Duwamish Waterway, near Wells MW -42 and DM -8. This well is not presently monitored as part of the approved monitoring plan. Six wells located upgradient of the barrier wall are proposed for abandonment (B5, Cl, DM -1A, DM -1B, DM -6, and E3). • Unused and un- maintained wells may become a pathway for surface releases, including stormwater, to enter and contaminate groundwater. • The four SVE wells are no longer used for the SVE interim measure. Above -grade components for the SVE interim measure either have been removed from the Site or will be removed as part of the planned demolition. • The monitoring wells proposed for abandonment were installed to assess the nature and extent of affected groundwater during the site investigations conducted during the past 15 years prior to completion of the HCIM. The nature and extent of affected groundwater have already been determined, so the original purpose of these wells has been fulfilled. Monitoring wells needed for performance monitoring and to assess potential migration of Site constituents have been identified and included in an ongoing groundwater monitoring program. • The HCIM has been in operation for more than two years and is regularly monitoring in accordance with the approved monitoring plan. The unused wells are not needed to assess performance of the HCIM system. 1:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 8 A well abandonment report will be prepared after completing abandonment work to document the abandonment method and clearly identify the abandoned wells. If it is not possible to locate a well, the affected well(s) will be identified in the well abandonment report. The well abandonment report will include a complete inventory of wells known or suspected to remain at the Site. It should be noted that future development plans may include construction of buildings or facilities at the Site that may require abandonment of additional groundwater wells. If EPA approves the proposed change in groundwater monitoring prior to implementation of this Redevelopment Work Plan, additional wells may be proposed for abandonment. Container Properties will notify EPA of future plans that require abandonment of any additional Site wells prior to finalizing development plans and prior to abandoning any wells not specifically requested by this plan. The wells that are not abandoned will be maintained and retrofitted as described in Sections 4.2.3 and 4.5. 3.2 REDEVELOPMENT DESIGN Redevelopment of the western parcel will be done after completing demolition, as described in the Demolition Work Plan, and well abandonment, as described above in Section 3.1. Redevelopment will include installation of a new stormwater collection and discharge system, grading of the area to promote drainage, and paving of the area with asphalt. The design for these elements is presented below. 3.2.1 Drainage Design Stormwater runoff from the western parcel is presently directed to the Duwamish Waterway through an existing outfall located near the northwestern corner of the Site (see Drawing 1, Appendix C). The existing stormwater drainage system will be abandoned in place and replaced by a new stormwater collection and treatment system. The new collection and treatment system will direct stormwater runoff through a Vortechs® water quality system that will treat and discharge stormwater to the existing 36 -inch storm sewer that crosses the property and discharges to the eastern portion of Slip 6 (see Drawing 3, Appendix C). Abandonment of the existing stormwater collection and discharge system will be done as follows: • Disconnect the discharge line near the northwest corner of the Site from the collection system by excavating to the line and removing a section of sewer; • Plug the line leading to the Duwamish with cement - bentonite grout to prevent flow through the line; and J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Z Geomatrix 9 • Remove catch basins leading to the sewer lines. The storm sewers will be left in place after disconnecting them from the discharge line. Geomatrix The design for the new stormwater collection and treatment system is shown on Drawing 3 (Appendix C). As shown, the Site will be graded to create two east -west rending ridgelines that will direct runoff to three lines of catch basins. One line of catch basins will be located near the northern property line, one in the low area in the central portion of the area between the two ridge lines, and one along the southern portion of the western parcel. The catch basins will discharge to a north -south collector sewer that will direct the collected stormwater toward the southeast corner of the western parcel where it will enter a Vortechs water quality unit. All catch basins, storm sewers, and the Vortechs unit will be placed entirely within the vadose zone, above the water table. As shown on the drawing, the storm sewers will be located near the barrier wall and will cross the barrier wall at several points. The Vortechs water quality unit provides treatment to remove sediment and oil/grease from the runoff prior to discharge. This unit and the stormwater discharge will be covered by a site stormwater permit from Ecology. A description of the Vortechs water quality unit is included in Appendix D. The entire western parcel will be paved with asphalt. The minimum asphalt thickness will be 4 inches. The asphalt cover will promote runoff and limit infiltration of rainwater to the contained area. It is expected that the grading and improved drainage system will reduce the amount of groundwater that must be recovered inside the contained area to maintain the HCIM performance standard. 3.2.2 Site Security and Access Site security will be substantially modified due to redevelopment of the western parcel. As shown on Drawing 3 (Appendix C), a new fence will be placed along the eastern boundary of the western parcel. Two man gates will be placed in the fence that will be kept locked except when access is needed. Access to the western parcel will be through the former Paccar site, currently being leased by IAAI, the lessee for the western parcel. The fence will be a 6 -foot tall chain -link fence with three strands of barbed wire. This fencing may he supplemented by additional fencing after the Site has been occupied by IAAI. The conditions of the lease require IAAI to provide ready access to Container Properties or Container Properties' representatives for routine operation of the HCIM and for groundwater J:\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 10 J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix monitoring or sampling. In addition, IAAI must provide access to the former Rhone- Poulenc site to EPA during reasonable hours. A copy of the lease agreement is included as Appendix E. Future access to the western parcel will be through the IAAI facility. Future access to the eastern parcel will be through the existing access gate. 11 4.0 CONSTRUCTION PLAN Redevelopment construction will be carried out as a series of discrete, but interdependent, activities. Each activity has its own implementation and control requirements for proper execution of the work. The following major construction activities are planned for this project: • Mobilization • Site preparation - Erosion and Sedimentation Control Measures - Well Abandonment - Well Protection - Pretreatment System Protection • Stormwater Management System Installation • Grading • Paving • Fencing • Well Retrofitting Extraction Wells Hydraulic Control Wells Monitoring Wells • Demobilization W Geomatrix A discussion of each activity is provided below. The sequence of execution is indicated in the project schedule (Section 5.0). All subsurface construction will be completed by an experienced environmental construction contractor using employees fully trained in accordance with OSHA HAZWOPER requirements specified in 49 CFR 1910. A Health and Safety Plan has been included as Appendix F. 4.1 MOBILIZATION Mobilization includes moving equipment and facilities needed for redevelopment to the Site and preparing to commence construction. Mobilization will be completed prior to the start of redevelopment construction. Temporary facilities will be established as necessary as part of mobilization. The perimeter security fencing will be inspected and any portions damaged or J: \8764.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 12 _Z- Geomatrix missing will be repaired as needed. This inspection will include the temporary fencing enclosing the western parcel. The temporary fence will be located to designate the boundary between the western and eastern portions of the Site. A temporary field office, sanitary services, and utilities, if needed, will be established on the eastern parcel. No subsurface work will be conducted on the eastern parcel. These facilities will only be established as necessary to complete redevelopment of the western parcel, as described in this Redevelopment Work Plan. 4.2 SITE PREPARATION Site preparation includes work necessary to prepare the western parcel for redevelopment construction. This work includes installation of temporary erosion and sedimentation control measures, abandonment of monitoring wells as approved by EPA, and protecting the monitoring and control wells that will remain active. Each of these tasks is described below. 4.2.1 Erosion and Sediment Control Measures Redevelopment construction will be completed in accordance with the general construction stormwater permit covering the Site. A SWPPP has been prepared in accordance with the general construction stormwater permit and the Stormwater Manual for Western Washington issued by Ecology and is attached as Appendix G. Silt fences and filter socks will be used to prevent runoff of sediment from the western parcel during redevelopment construction. The active stormwater catch basins located in the eastern parcel will be protected by placement of filter geotextile under the grate or another technique compliant with the Stormwater Manual for Western Washington. The north, east, and south boundaries of the western parcel will be lined with silt fencing to prevent sediment runoff. No silt fence is needed along the western boundary due to the existing dike that prevents runoff to the west. The stormwater discharge sewer located near the northwest corner of the western parcel will be abandoned and sealed as described below in Section 4.3. Sealing of the existing discharge line will prevent discharge from the western parcel to the Duwamish Waterway. The western parcel will be inspected to identify runoff pathways. If any segment of the western parcel is found to drain outside the property, then protection or diversion measures, such as silt fencing, will be installed in accordance with the SWPPP (Appendix G). The filtration devices and silt fences will be inspected and cleaned periodically, as needed and in accordance with the stormwater permit. Accumulated sediment will be returned to the western parcel and placed beneath the cover material prior to final grading and paving. J:\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 13 w� Geomatrix 4.2.2 Well Abandonment The wells proposed for abandonment in Table 1 will be abandoned by a licensed driller in accordance with Ecology regulations (WAC 173 -160). The wells to be abandoned will be marked in the field by a geologist familiar with the Site and with the ongoing groundwater monitoring program. If a well cannot be located by visual observation of the surface monument, a metal detector will be used to attempt to locate the well. If a well cannot be located with the metal detector, it will be listed as unconfirmed in the redevelopment implementation report. The location of wells abandoned will be shown on a site map in the implementation report. The method used for well abandonment will be described in the implementation report. Waste generated during well abandonment will be placed in covered, lined roll -off boxes and managed as described below in Section 4.7. 4.2.3 Well Protection The active, remaining groundwater wells in the western parcel will be protected during redevelopment construction. Five existing monitoring wells currently have aboveground monuments. After completing grading and paving, all active monitoring and extraction wells, including the wells with above grade completions that are located east of the dike along the Duwamish Waterway, will be adjusted/raised as needed to attain final site grade and completed with flush surface monuments, as described below in Section 4.5. It is expected that the existing traffic -rated surface monuments for the monitoring wells will be adequately protective of the wells during filling and grading of the western parcel. Coordinates will be determined for each active well using a GPS unit prior to filling. For wells with above grade completions, the protective casing and bollards will be removed and the casing will be cut so that it is below existing grade, and the casing will be sealed with a locking well cap. A small metal plate will be placed over the casing at these wells. Finally, the bolts will be removed from all flush well covers before filling occurs to facilitate retrofitting the wells after grading and paving have been completed. The metal well monuments will facilitate fording the wells after the area is paved. The three extraction wells are completed within traffic -rated concrete vaults. These vaults are expected to be adequately protective of the extraction wells during grading and paving. However, the location of the extraction wells will be determined with a GPS unit. The steel plates and concrete vaults will distribute the load from earthmoving and grading equipment working above the wells. The steel plates and metal cover on the extraction well vaults will J:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 14 Geomatrix facilitate location of the wells after grading and paving are complete. The well locations will be confirmed using a metal detector after paving is complete. 4.3 EARTHWORK There will be three different categories of earthwork for this project, including filling/grading, trenching, and general excavation. Filling and grading will be done to lower high spots within the western parcel and to generally raise the site elevation to promote runoff of rainwater. Trenching earthwork will be done along the alignment of the new underground stormwater sewers described in Section 4.4. General excavation will done using excavators and hand - excavation for installation of catch basins, the stormwater treatment unit, and to abandon the existing underground storm sewer line leading to the Duwamish Waterway. The following subsections described each type of earthwork. All earthwork will be clone using an environmental contractor and workers fully trained in accordance with 49 CFR 1910. The attached Health and Safety Plan (Appendix F) will be provided to the environmental contractor prior to conducting the earthwork. An exclusion zone will be clearly marked around the area to be filled and graded. The exclusion zone will have a single, clearly marked entry and exit point. Equipment used for earthwork will be decontaminated prior to use at the Site. All equipment potentially contacting site 'soil will be decontaminated prior to leaving the exclusion zone. A wheel wash will be located just inside the exclusion zone entrance /exit to clean wheels for trucks exiting the exclusion zone after delivering material used in filling the area or for removal of waste. 4.3.1 Filling/Grading The western parcel will be filled and graded to promote surface water runoff. Prior to grading, the surface structures and building slabs will be demolished, as described in the Demolition Work Plan (Geomatrix, 2005). Much of the western parcel will be filled using crushed, recycled concrete. It is estimated that the general elevation of the western parcel will be raised by about 18 inches. However, several small areas are present that exceed the final grade needed to promote uniform rainfall runoff The approximate location and extent of these areas are shown on Drawing 2 (Appendix C). The elevated areas include mounded soil within the western parcel, the secondary containment berm around the storage tank, and filled areas beneath buildings or foundation slabs. As noted previously, slabs and surface foundations will be removed during demolition. I: \8769.000 RC[ R- P \060\RP -Site Develop WP- ver- 03.doc 15 Grading of the elevated areas will be conducted after completing the demolition described in the Demolition Work Plan (Geomatrix, 2005). The following procedures will be conducted to grade the elevated areas: 1. Vegetation present in elevated areas will be cleared and grubbed to expose the mounded soil. 2. The elevated areas cleared of vegetation and concrete slabs will be visually inspected by an experienced environmental professional to identify the potential presence of industrial waste or highly impacted soil. a. If the exposed materials are found to consist primarily of soil, without substantial rubble or debris, it will be concluded that no waste or waste constituents are present and the materials will be used to fill in low areas within the western parcel. If substantial rubble or debris is present or if discolored or oily material is found in the exposed materials, it will be concluded that waste is present and the following actions will be implemented: (i) Geomatrix Samples will be collected in accordance with applicable Site quality assurance project plans (QAPPs) previously approved by EPA. The samples will be analyzed for RCRA metals (EPA Method 6010B), volatile organics (EPA Method 8260), semivolatile organics (EPA Method 8270, including tentatively identified compounds), and ppm range PCB Aroclors (EPA Method 8082). (ii) EPA will be notified regarding the identification and characterization of the waste. (iii) Arrange for proper management and disposal of waste, if required, in accordance with all applicable federal and state regulations as described in Section 4.7. b. If no evidence of industrial waste is observed, the material will be evaluated for evidence of excessive construction debris or rubble. (i) Excessive rubble or debris present in the material will be removed and placed in a covered roll -off container for characterization in accordance with the RCRA and Washington Dangerous Waste regulations (WAC 173 -303) and off -site disposal. 3. If no evidence of industrial waste or excessive debris /rubble is observed, the soil will be pushed to lowareas using a bulldozer. 4. The graded materials will be covered as necessary to achieve final grade elevations using crushed, recycled concrete. J:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 16 J:\8760.000 RCI R- P\060 \RP -Site Develop WP- ver- 03.doc i;= Geomatrix The western parcel will be filled using crushed, recycled concrete to attain the final grade shown in the project drawings in Appendix C. Filling will be placed and compacted in lifts to achieve the compaction specifications for redevelopment. The area will then be paved with asphalt. 4.3.2 Trenching All new piping for the new stormwater management system will be installed below grade within excavated trenches. The trenches will be excavated using a trencher or excavator after filling and grading have been completed. The width of the trenches will be 2 to 3 feet, and the depth will vary from about 2.5 feet to about 6 feet below the final grade, as necessary to maintain the required slope for the sewer lines. Excavated soil will be placed on plastic sheeting, along the trench during installation of the underground lines. Bedding soil will be placed in the bottom of the trench. The bedding soil will be either site soil excavated from the trench (if it has suitable physical characteristics) or clean, imported sand. The bedding soil will be placed in the bottom of the excavation and compacted as necessary to attain the specified slope for the sewer line. After the placement of the sewer lines, the trenches will be backfilled with the excavated soil. The backfilled soil will be compacted in layers no thicker than 12 inches before compaction. Trenching will be done in sections so that trenches are not kept open for more than two to three days. Plastic sheeting used for excavated soil will be disposed in accordance with applicable regulations after completing trenching. The depth to groundwater in the western parcel is presently greater than about 16 feet below the existing grade, including the area east of the subsurface barrier wall. Inside the barrier wall, the depth to groundwater is presently more than about 19 feet below existing grade. Groundwater will not be encountered since trenching will be less than about 6 feet below the finished grade (which will be 0 to 1.5 feet greater than the present grade). Since the trenches will be well above the water table, it will not be necessary to repair the small, shallow section of wall that must be removed to install the storm sewer lines passing through the wall. Trenches crossing through the subsurface barrier wall will be backfilled with excavated materials. 4.3.3 General Excavation General excavation will be done to install catch basins, the stormwater treatment unit, to install new surface completions for the two wells used to monitor groundwater levels for hydraulic control, DM -8 and MW -49, and to extend monitoring wells to the new grade and replace the wellhead completion. General excavation may be done by an excavator, backhoe, or hand excavation as appropriate to the project needs. Excavation for installation of catch basins and 17 ; Geomatrix well completion will be shallow, generally less than 2 to 3 feet below final grade. However, some catch basins may be up to 6 feet below final grade. Installation of the Vortechs stormwater treatment unit will require excavation to 10 -11 feet below final grade. The catch basins will be installed simultaneously with the sewer lines. Excavations for the catch basins will be done using a backhoe, excavator, and/or hand excavation. Excavated soil will be placed on a sheet of plastic adjacent to the excavation. After placing the catch basin in the excavation, the excavated soil will be used as backfill around the catch basin and/or for backfilling the trench. Fill material (crushed, recycled concrete) will be placed around the catch basin and graded to establish the final grade. The Vortechs unit will be installed prior to filling and grading. The excavation needed to accommodate the Vortechs unit will be approximately 10 feet by 20 feet at the bottom with a depth of 10 to 11 feet below final grade. The excavation will be extended to the existing 36- inch King County storm sewer so that the discharge line from the Vortechs unit can be tapped into the county sewer line. The location for the Vortechs unit and the connection to the King County sewer is outside the barrier wall (see Section 4.4). As noted previously, the depth of groundwater is presently more than 16 feet below grade in the area where the Vortechs unit will be placed; therefore, groundwater will not be encountered in the excavation. The excavation for the Vortechs unit will be done using an excavator or backhoe. Since the location for the Vortechs unit is outside the barrier wall, it is expected that contamination will not be encountered. Excavated soil will be placed on plastic sheeting adjacent to or near the excavation. The excavated soil will be visually inspected for evidence of waste materials and high levels of contamination. The following evaluation procedures will be followed to assess excavated soil for potential waste materials: 1. If the excavated soil contains discolored or oily material, it will be concluded that waste is present. The waste - containing soil will be placed within covered roll -off containers and the following actions will be implemented: (i) Samples will be collected in accordance with applicable site quality assurance project plans (QAPPs) previously approved by EPA. The samples will be analyzed for RCRA metals (EPA Method 6010B), volatile organics (EPA Method 8260), semivolatile organics (EPA Method 8270, including tentatively identified compounds), and ppm range PCB Aroclors (EPA Method 8082). (ii) EPA will be notified regarding the identification and characterization of the waste. J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 18 2. If no evidence of waste is observed, the soil will be used for backfill around the Vortechs unit and for filling low areas within the contained portion of the western parcel. J: \8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc Geomatrix (iii) Arrange for proper management and disposal of waste, if required, in accordance with all applicable federal and state regulations as described in Section 4.7. Soil will also be excavated around the monitoring and extraction wells to re- complete the wells to match the final grade. Details concerning well retrofitting are presented in Section 4.5. It is expected that soil around the well heads will be excavated by hand. Excavated soil will be placed on plastic sheeting adjacent to the hole. After exposing the well head, the old surface monument and adjacent material (concrete, asphalt) will be removed from the excavation and disposed of as construction debris. After refitting the well, the excavated soil will be returned to the excavation and compacted. The area around the refitted wells will be graded to match the final grade near the well. 4.4 STORMWATER MANAGEMENT SYSTEM The new stormwater collection and treatment system will be installed in the western parcel to collect and treat surface runoff in accordance with the stormwater permit. The drainage lines, catch basins, and Vortechs unit will be installed after grading has been completed and prior to final paving. The locations for the catch basins, collection lines and the Vortechs unit are shown on Drawing 3 (Appendix C). The Vortechs unit will be installed near the southwest corner of the western parcel to remove entrained oil and sediment from western parcel runoff. The discharge from the Vortechs unit will enter the existing King County 36 -inch storm sewer main that empties to the eastern end of Slip 6. This new stormwater system will be constructed in accordance with the requirements of a stormwater permit covering the western parcel. The individual catch basins will be placed on the elevations shown on Drawing 3 (Appendix C) to ensure proper drainage. Earthwork associated with installation of the stormwater management system issues are discussed in Section 4.3. The storm drains and catch basins will be constructed using conventional materials. The catch basins will be prefabricated concrete basins fitted with cast iron grating and capable of supporting heavy vehicular traffic. The catch basins will be placed in excavations prepared in accordance with standard practice. Storm sewers will be constructed of commercially available PVC sewer piping with water tight connections. The sewer lines will vary from 8 to 15 inches in diameter. The sewer lines will be placed into trenches prepared in accordance with recommendations of the sewer manufacturer. 19 r = Geomatrix The Vortechs unit is a proprietary unit specifically designed to treat stormwater runoff. A product brochure is included in Appendix D. The unit is a dual - chamber treatment system installed entirely below grade. Stormwater enters the first chamber tangentially, inducing a circular flow pattern that enhances separation of suspended material and grit. The second chamber includes an underflow weir designed to separate floating oil and additional suspended solids from the runoff. The treated runoff then discharges from the Vortechs units via an overflow weir. The discharge from the Vortechs unit will enter a PVC storm sewer to direct runoff to the King County sewer line, which empties to Slip 6. Three manholes are included in the Vortechs unit to allow periodic cleanout of accumulated sediment and oil. The unit will be operated and maintained in accordance with the facility stormwater permit and manufacturer recommendations. 4.5 WELL RETROFITTING The active monitoring wells and the three extraction wells will be retrofitted with new surface completions to match the new surface elevation. As listed in Table 1, a total of 40 wells must be retrofitted to match the new grade. Each monitoring well will be located using GPS and a metal detector after grading and paving have been completed. The three extraction wells and the two level control wells will be fitted with a new vault or surface monument prior to paving. Details concerning retrofitting the wells are presented below. 4.5.1 Extraction Well Retrofitting The three extraction wells used for the HCIM are located within existing concrete vaults. These vaults are rated for truck traffic. A new vault will be placed over each of the existing well vaults to match the new grade. This approach will eliminate the need to remove the existing vaults and significantly reduce the potential for damaging the wells. It will also be unnecessary to extend the wells, thereby avoiding downtime for the extraction wells. The new vault will be slightly larger than the existing vaults. Soil above and adjacent to the extraction well vaults will be excavated as described above in Section 4.3.3. Upon exposing each well, the total depth of the well will be plumbed to assess the well for damage. The new vaults will be open- bottom prefabricated concrete vaults rated for truck traffic. The new vaults will be cemented in place and set to match the new grade at each well location. The top of the new vault will be approximately Y2 -inch above the asphalt pavement that will be placed around the wells. The access doors on the existing vaults will be removed to facilitate access to the extraction wells. J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 20 4.5.2 Hydraulic Control Well Retrofitting Two wells (MW -49 and DM -8) are used to control groundwater extraction for the HCIM. These wells are equipped with pressure transducers to measure the groundwater level and relay the level to a programmable logic controller (PLC) to automatically control the wells and to a data recorder to maintain a record of the groundwater levels inside and outside the barrier wall. Due to the filling and grading of the western parcel, it will be necessary to extend the well casing for these two wells and to install new surface monuments. Due to the conduit and wiring needed to measure the transducer signal, the approach for retrofitting these two wells is different than for the monitoring wells described in Section 4.5.3. Retrofitting of the two control wells will be completed with minimal loss of groundwater level monitoring data. The two control wells will be retrofitted by placing a double wye on the existing casing and extending the casing to the new grade. An 18" monument will be placed over the well head and cemented in place. The design for the well head is shown on Drawing 4 (Appendix C). The transducer cable will exit the well head through a "wye" in the well head. The cable will enter a below -grade conduit through the side wall of the well monument. The conduit will direct the cable to a junction box where the cable will be connected to communication wiring for the PLC. A vent tube will be attached to another leg of the wye; the tub will also exit the surface monument through the conduit. The vent line is necessary to avoid pressuring the well and to ensure accurate readings for the transducers. A standard well cap will seal the well through the last leg of the wye, which will allow well access for sampling or manual water level measurement. The cable and vent tube will be connected to the well head using a water- tight compression connector. Retrofitting of the two control wells will be done as follows: 1:\8765.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix 1. Prior to filling and grading, the existing transducers will be removed from the two control wells and replaced with battery operated transducer /data loggers to temporarily record groundwater levels during grading and paving. The groundwater recovery system will be placed in manual operation mode, with one pump running continuously until the transducers are re- installed. The temporary transducers will be calibrated. 2. Underground PVC conduit will be run to the well head prior to filling and grading. The conduit will run from each well head to a junction box connected to the PLC. 3. The control wells will be prepared as described above in Section 4.2.3. The battery operated transducer /data loggers will monitor and record groundwater levels until the permanent transducers are re- installed. 21 11. The new top -of -casing elevation will be surveyed by a licensed surveyor. The control wells will be returned to normal service after completing retrofitting. J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix 4. After filling, grading and paving have been completed, the two control wells will be located and excavated for retrofitting. 5. Upon exposing each well, the total depth of the well will be plumbed to assess the well for damage. 6. The existing surface monument will be removed from each well taking care to avoid damage to the well casing. 7. The existing well casing will be extended so that the top of casing is near the new surface grade. A four -way wye will be installed in the casing. The existing casing and extension will be 2 -inch Schedule 80 PVC; all connections will be threaded. 8. A new, oversized surface monument will be installed over the well head. The casing will be set in concrete so that the top of the monument is approximately 1/2-inch above the asphalt to minimize entry of surface water into the well head. 9. The conduit will be extended into the surface monument by cutting a hole into the monument. The hole will be sealed with concrete. 10. The temporary transducer /data logger will be removed and the original transducer will be reinstalled and connected to the PLC. The vent tube will be connected to the well and run to the junction box. The transducer will be calibrated and checked for accuracy. 4.5.3 Monitoring Well Retrofitting The remaining active monitoring wells have flush monuments. These wells will be raised to the finish grade by extending the well casing and installing new, flush- mounted monuments by a licensed driller. The new flush monuments will be rated for truck traffic Each well will be located after paving is complete using GPS and a metal detector. The asphalt will be saw cut around the well location and soil will be excavated to expose the old monument. Upon exposing each well, the total depth of the well will be plumbed to assess the well for damage. The monument will be removed, taking care to avoid damage to the well casing. The casing will then be extended appropriately for the new surface graded using threaded, Schedule 80 PVC casing. The new monument will be set in concrete so that the top of the casing is approximately 1/2-inch above the pavement to prevent stormwater runoff from entering the monument. The new top -of- casing elevation will be surveyed by a licensed surveyor. 22 J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 4.8 DEMOBILIZATION Upon completion of paving and well retrofitting, subcontractors will demobilize from the western parcel. All equipment used in the exclusion zone will be decontaminated prior to removal from the Site. The equipment decontamination and wheel wash station will be Geomatrix 4.6 PAVING The western parcel will be paved with asphalt after filling and grading have been completed. The asphalt will be placed directly on the crushed recycled concrete base. The asphalt pavement will be standard asphalt concrete and will be placed to form a continuous cover of the western parcel with a minimum thickness of 3 inches. The asphalt pavement will be placed around the catch basins and recovery well vaults to form a continuous cover. The surface of the asphalt will be sealed using commercially available materials. As noted above, the finished asphalt cover will be cut to extend monitoring wells to the new grade. The area around the new well monuments will be finished with Portland cement. 4.7 WASTE MANAGEMENT The site redevelopment project is expected to generate trash, spent personal protective equipment (PPE), abandoned well materials, construction debris and, possibly, soil contaminated with hazardous waste. No site dewatering is expected, as all excavation will be above the water table. Stormwater accumulation and management may be required. Stormwater will be collected and managed in accordance with the sto:rmwater permit. Any rainwater contacting excavated soil will be managed as contaminated water and will be treated and discharged to the King County sewer. The trash generated during the course of the project will be placed in waste bins and disposed offsite as municipal waste. Used PPE will be stored in plastic bags and disposed along with the trash, unless obvious contamination is noted. If used PPE is obviously contaminated, it will be disposed at a permitted, off -site facility in accordance with the Washington Dangerous Waste regulations, (WAC 173 -303). Contaminated soil identified as industrial waste will be temporarily shored onsite in covered, lined roll -off containers pending characterization in accordance with Washington Dangerous Waste regulations (WAC 173 -303). The materials containing industrial waste will be disposed in a permitted, off -site disposal facility in accordance with the Dangerous Waste regulations. The covered roll -off containers will prevent rainwater from contacting the materials and will prevent contamination of runoff. Debris from abandonment of wells will be managed as Dangerous Waste. 23 J: \8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc Geomatrix dismantled. The decontamination station will be cleaned and decontaminated prior to dismantling. Decontamination water will be managed as Dangerous Waste, as described above in Section 4.7. The decontamination station will then be dismantled. The wooden planks used in the decontamination station will be disposed of as hazardous waste. All other materials will be disposed as construction debris, since the plastic liner and other materials will be decontaminated. Any disturbed surfaces will be repaired. All trash and residuals from construction will be removed from the Site in accordance with Section 4.7. 24 5.0 SCHEDULE za t Geomatrix Redevelopment of the western parcel will commence after completing demolition, as described in the Demolition Work Plan (Geomatrix, 2005). It is expected that demolition will be completed during the first part of 2006. Redevelopment is expected to be complete by April 1, 2006. It is expected that the redevelopment work covered by this Redevelopment Work Plan will require approximately two months to complete. Therefore, it is projected that redevelopment work will commence on February 1, 2006.

Washington Surface Water Design Manual (KCSWDM). -2- 10265.001.doc [07/05/05] Applicant Responses: Agency Comments b. Ground: Please respond to all questions. Use separate sheets as necessary. 1. Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known. In accordance with the Interim Measure Construction Work Plan (IMCWP), approved by EPA (URS, 2002). the site was required to install subsurface low permeability barrier walls surrounding the western portion of the site, to the maximum extent practicable, containing the environmentally impacted portion of the site. A system of groundwater extraction wells and a pre- treatment system were installed to pump groundwater from . the inside of the contained area thereby creating an inward groundwater gradient. The pre - treated groundwater is discharged to a publicly owned treatment works, owned and operated by King County. and permitted under the Clean Water Act. The groundwater pre- treatment system is an integral part of the hydraulic control interim measure and will, therefore, be relocated as part of the redevelopment of the site. Groundwater withdrawal will be equal to the amounts currently withdrawn. 2. Describe waste materials that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc).

NOTES This map is for use in administering the National Flood Insurance Program; it does not necessarily N g, particular) from identify all areas subject to flooding, y local drainage sources of small size• or all planimetric features outside Special Flood Hazard Areas. Coastal base flood elevations apply only landward of 0.0 NGVD, and include the effects of wave action; these elevations may also differ significantly from those developed by the National Weather Service for hurricane evacuation planning. Areas of Special Flood Hazard (100 -year flood) include Zones A. AE, AH, AO, A99. V, and VE. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. Boundaries of the floodways were computed at cross sections and interpolated between cross sections. The floodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Management Agency. Floodway widths in some areas may be too narrow to show to scale. Floodway widths are provided in the Flood Insurance Study Report. This map may incorporate approximate boundaries of Coastal Barrier Resource ' System Units and /or 'Otherwise Protected • Areas established under the Coastal Barrier Improvement Act of 1990 (PL 101 -591). Corporate limits shown are current as of the date of this map.

Box 1043 City, State, Zip: Kent, WA 98035 -1043 Telephone: (253) 813 -9410 Directions This Screening Checklist has been designed to evaluate the potential for your project to result in potential "take" of chinook salmon, coho salmon, or cutthroat trout as defined by Section 9 of the Endangered Species Act. The checklist includes a series of "Yes' or "No" questions about your project, organized into four parts. Starting with Part A on Page 1, read each question carefully, circle "Yes" or "No," and proceed to the next question as directed by the checklist. To answer these questions, you may need to refer to site plans, grading and drainage plans, critical areas studies, or other documents you have prepared for your project. The City will evaluate your responses to determine if "take" is indicated. 1 1 -0 Will the project require any form of grading? Grading is defined as any excavating, filling, clearing, or creation of impervious surface, or any combination thereof, which alters the existing ground surface of the earth (see Tukwila Municipal Code (TMC) Chapter 18.06, Zoning Code, Page 18 -11). Please circle appropriate response. NO - Continue to Question 2 -0 - Continue to Question 1 -1 2-0 ill the project require any form of clearing? Clearing means the removal or causing to be removed, through either direct or indirect actions, any vegetation from a site (see Chapter 18.06, Page 18 -8). Please circle appropriate response. 4 1 1:1 Continue to Question 3 -0 S - Continue to Question 2 -1 3-0 Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, Page 18 -15). Please circle appropriate response. 0 Continue to Question 4-0 S - Continue to Question 3 -1 4-0 ' Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -11). This includes fuel or other chemicals stored on -site during construction. Please circle appropriate response. 4;) Continue to Question 5 -0 ' S - Continue to Question 5 -0 5-0 Will the project result in the withdrawal, injection, or interception of groundwater? Examples of projects that may affect groundwater include, but are not limited to: construction of a new well, change in water withdrawals from an existing well, projects involving prolonged construction dewatering, projects installing French drains or interceptor trenches, and sewer lines. For the purpose of this analysis, projects that require a geotechnical report pursuant to the requirements of TMC 18.45.060 and 18.45.080E.4, or would require a geotechnical report if not exempt under TMC 18.45.080A, should answer Yes. Please circle appropriate response. SID Continue to Question 6-0 S - Continue to Question 6 -0 Part A: Please review and answer each question carefully. Consider all phases of your. project including, not limited to, construction, normal operation, potential, emergency, operation, and ongoing anti scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 2 1 I i i i i i i i i i i i I Part A (continued) 6-0 Will the project involve landscaping or re- occurring outdoor maintenance that includes the regular use of fertilizers, pesticides, or herbicides? This does not include the one -time use of transplant fertilizers. Landscaping means natural vegetation such as trees, shrubs, groundcover, and other landscape materials arranged in a manner to produce an aesthetic effect appropriate for the use of the land (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18- 13). For the purpose of this analysis, this includes the establishment of new lawn or grass. Please circle appropriate response. NO — Checklist Complete (YESj— Checklist Complete Part B: Please answer each question below for projects that include grading. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -1 Will the project involve the modification of a watercourse bank or bank of the Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This includes any projects that will require grading on any slope leading to a river or stream, but will not require work below the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. Continue to Question 1 -2 S - Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 - Continue to Question 1 -3 1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development. Please circle appropriate response. NO - Continue to Question 2 -0 ©- Continue to Question 1-4 3 2 -1 Will the project involve clearing within 200 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? Please circle appropriate response. NO - Continue to Question 3 -0 YES - Continue to Question 2 -2 2 -2 Will the project involve clearing of any trees within 200 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? A tree is defined by TMC 18.06.845 as any self - supporting woody plant, characterized by one main trunk, with a potential diameter - breast- height of 2 inches or more and potential minimum height of 10 feet. Please circle appropriate response. NO - Continue to Question 2 -3 YES - Continue to Question 2 -3 2 -3 Will the project involve clearing of any evergreen trees from within 200 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis evergreen means any tree that does not regularly lose all its leaves or needles in the fall. Please circle appropriate response. NO - Continue to Question 2-4 YES - Continue to Question 2-4 2-4 Will the project involve clearing within 100 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? Please circle appropriate response. NO - Continue to Question 3 -0 (Page 1) YES - Continue to Question 2 -5 2 -5 Will the project involve clearing within 40 feet of the ordinary high watermark of a watercourse or the Green/Duwamish or Black Rivers? Please circle appropriate response. NO - Continue to Question 3 -0 YES - Continue to Question 3-0 1-4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground.

Each Vortechs' System is custom designed based on: » Removal Efficiency Goals » Drainage Area » Regional Rainfall Intensity Distribution » Design Flow » Site Runoff Coefficient and Time of Concentration » Anticipated Pollutant Characteristics Vortechs System Sizing Methodology: the Rational Rainfall Method Differences in local climate and topography make every site unique, so it is important to take these factors into consideration when choosing a stormwater treatment system. Therefore Vortechnics developed the Rational Rainfall fvlethodm to accurately design each Vortechs* System. The sizing methodology combines site - specific information, including local historical precipitation records, with laboratory- generated performance data corroborated by third -party field studies, ensuring accurate long -term performance. Short duration rain gauge records from across the United States and Canada were analyzed by Vortechnics to determine the percent of the total annual rainfall that fell at a range of intensities. One trend was consistent at all sites: the vast majority of precipitation fell at low intensities and high intensity storms contributed relatively little to the total annual depth. These intensities, along with the total drainage area and runoff coefficient for a specific site, are translated into flow rates using the Rational Rainfall MethodTM. Based on the flow rates calculated for each intensity, an operating rate within a proposed Vortechs' System is determined. Finally, a removal efficiency is selected for each operating rate based on anticipated pollutant characteristics and on full -scale Laboratory tests. The relative removal efficiencies at each operating rate are summed to produce a net annual pollutant removal efficiency estimate, Vortechnics typically selects a system size that will provide an 80 percent annual total suspended solids (TSS) load reduction based on laboratory- generated performance curves for 50- micron sediment particles, however the Rational Rainfall MethodTY can accommodate other removal efficiencies or particle sizes. it can also be used to estimate annual hydrocarbon load reductions. Once a system size is established, the internal elements of the system are designed based on information provided by the site engineer. Flow control sizes and shapes, sump depth, spill storage capacity, sediment storage volume and inlet and outlet orientation are determined for each system. In addition, bypass weir calculations are made for offline systems. (2134 mm) • T ypicai ,.. Inlet e' Invert pm en) ;: Typical Top ano Sides Sealed to.

Sites that generate larger flows can be treated using cast - in -place systems. Vortechs''' Systems can be configured in both online and offline orientations depending on water quality objectives and site constraints. They can also be designed to accommodate various inlet and outlet pipe orientations. To provide a tangential inlet to the swirl chamber, the inlet pipe must enter at a corner and at a 90 degree angle to the inlet wall. Outlet pipes can exit the end or the side of the system at most angles. Standard Vortechs' System models, peak treatment flow rates, and dimensions are listed below.

Low Intensity Storm Most storm events (85 percent) do not exceed the two -month storm intensity. During this low intensity storm flow, the water level within the Vortechs"' System will rise above the top of the inlet pipe, reducing inflow velocity and turbulence. Oil and fine sediments are usually washed off paved surfaces during these events, and the Vorteche System treatment efficiencies are in the 80 to 90 percent range for typical urban runoff sediment High Intensity Storm High intensity storms are infrequent, and storm flows have sufficient energy to wash off the largest sediment particles and pieces of debris. When the high flow control approaches full discharge within the Vorteche System, storm drains are flowing at peak capacity. The Vortechs" System can accommodate flows up to the specified design storm (i.e. 10 -year storm). Treatment efficiencies remain constant during this phase. Learn More! Call 877.907.8676 or visit us at www.vortechnics.com Medium Intensity Storm During a medium intensity storm, which occurs with a frequency of one to two years, remaining oil washes off pavement, and larger sediment particles and debris are now transported into the Vorteche System. As flow increases, the water level rises above the low flow control and the tank begins to fill. With the inlet submerged, the oily layer is above the influent flow path, preventing re- entrainment of floating pollutants. Swirling action increases at this stage, which increases sediment removal rates. Storm Subsidence Treated runoff is decanted out of the Vortechs" System at a controlled rate, restoring the water level to a low, dry- weather volume. This reveals a conical pile of accumulated sediment in the center of the grit chamber. Besides facilitating inspection and cleaning, the low water level significantly reduces maintenance costs by reducing pump -out volume.

The HSP establishes the guidelines and requirements for the safety of Geomatrix personnel, personnel contracted by Geomatrix, and site visitors throughout the duration of site activities. A copy of the HSP will be maintained at the site during all field operations. Contaminants of concern at the site include toluene, heavy metals and by- products of the Vanillin process including some mineral oils. This Health and Safety Plan (HSP) is designed to provide general support to all activities likely to be encountered in the execution of site investigation, design, or construction activities performed at the site. This HSP will address the specific tasks, hazards and controls associated with activities at the former Rhone- Poulenc Site. The HSP is subject to routine updates to ensure the adequacy of its coverage relative to changing contract and project specific needs. This plan will be reviewed at least annually or more often as deemed necessary by the Site Safety Officer. The purpose of this HSP is to summarize the health and safety hazard information for the tasks related to construction activities. Site background information, key personnel and their responsibilities, personnel medical qualifications and training requirements, site hazards analysis, hazard control measures, and emergency response procedures are provided in this document. Detailed information regarding the construction- related tasks is provided in the Work Plan and Field Sampling Plan for this project. It is essential that personnel associated with the field effort are aware of the nature and extent of the potential hazards associated with each task, as well as the need for safety planning and implementation of appropriate safety procedures, safety equipment, and control measures identified in this HSP to minimize the risk of exposure to these hazards. The HSP was prepared in accordance with the H &S standards, provisions, and requirements specified in the following regulations and guidance documents: • OSHA Occupational Safety and Health Standards. 29 CFR Parts 1910 and 1926. • WISHA Occupational Safety and Health Standards. WAC 296 -62, 296 -24 and 296 -155. • National Institute for Occupational Safety and Health (NIOSH). Pocket Guide to Chemical Hazards. Department of Health and Human Services. Health and Safety Plan Page 2 All Geomatrix personnel planning to visit the site must read, understand, and abide by this plan and sign the Acknowledgment of Understanding form attached to this plan. This plan will be reviewed by the site health and safety officer (SHSO) periodically, and any changes to this HSP must be approved by the Health and Safety Manager (HSM). During fieldwork mobilization, the Required Equipment and Personal Protective Equipment (PPE) Checklist (Figure 10 1) will be consulted to ensure that all health and safety - related supplies and equipment are available at the site. 1.2 SCOPE OF WORK For this plan, project activities have been broadly divided into the following tasks: Excavation and backfill of utility trenches Placement of underground piping and vaults Installation of underground piping Backfilling and compaction Grading Well abandonment Well retrofitting H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP\Redeve lopmentHASP- ver- 01.doc Health and Safety Plan Page 3 Figure 1 -1 Required Equipment and Personal Protective Equipment Checklist Safety Equipment Personal Protective Equipment (per person) Air - purifying respirator (full face) - on hand Cartridges (specify type: organic vaporTHEPA) — on hand SCBA Airline system X Safety boots Chemical- resistant boots with steel toes Chemical- resistant coveralls (specify type ) X Coveralls (Tyvek or cotton) X Hard hat Face shield (as needed) X Latex gloves (box - 12 pair) Viton gloves (box - 12 pair) X Nitrile gloves (box - 12 pair) Other chemical or heat - resistant gloves (specify type X Safety glasses with side shields or goggles X Ear plugs Ear muffs Other (specify) Misc.

H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 7 3.0 PERSONNEL MEDICAL QUALIFICATIONS AND TRAINING REQUIREMENTS The required qualifications depend on an employee's level of involvement at the site, the amount of time spent on site, and the specific tasks the employee will be involved in when on site. In accordance with a company Hazard Communication Program, workers will be trained on the hazards they are exposed to while working on the site. For assessment of medical and training qualifications, all personnel entering the site will have the approval of the SHSO. In addition to 40- hour hazardous waste initial and annual 8 -hr refresher training, all site personnel will participate in weekly briefings to discuss the effectiveness of controls and the need for revisions. All site workers will have Confined Space Entry training and training on the specific hazards associated with the site. This training will include coverage of bloodborne pathogens. In addition, members of the field crew dedicated to this project will have current Adult Cardiopulmonary Resuscitation (CPR) and First Aid training (Red Cross certified). This training will be obtained prior to commencing fieldwork at this site. Each team member must have a physical examination prior to participation in field activities to verify that the worker is capable of wearing respiratory protective equipment (if necessary), capable of working in a physically taxing environment, and free of medical conditions that may be aggravated while working on site. The HSM is contacted before the annual physical and afterward (if the occupational health physician poses additional questions or concerns). A copy of each employee's clearance letter and fit -test will be available on site, whereas the more extensive health records are kept in secured offices at the contracted clinic. The employee also receives his/her own copy of the individual medical report. In the specific case of the work performed under this task, the basic annual physical will meet the requirements for the work scheduled. If additional tasks are added or if the scope of work changes dramatically, the medical surveillance requirements will be modified as necessary.

Site activities may expose contaminated soil. Contaminants of concern at the site include toluene, heavy metals and by- products of the Vanillin process including some mineral oils. Potential respiratory, ingestion, and dermal exposure to soil, dust, wastewater, vapors and residue contaminated with chemicals are possible at the site. It is anticipated that airborne concentrations will be well below any regulatory limits for occupational exposure. The use of personal protective equipment to protect against these hazards will be utilized. 4.2 CHEMICAL HAZARDS The following category of chemical hazards are associated with site activities: • Site Constituents H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 9 The chemicals that are brought on site in order to conduct the work may be hazardous and subject to regulation under OSHA's Hazard Communication Standard (29 CFR 1910.1200). Site constituents are those which exist at the site and are the cause for conducting site activities. 4.2.1 Hazard Communication Materials Materials which are considered hazardous materials under the OSHA Hazard Communication Standard (29 CFR 1910.1200) may be used during this project. Proper chemical labeling, a current inventory of hazardous chemicals brought to the site, and Material Safety Data Sheets (MSDSs) will be provided at each project site. This project is not expected to store bulk quantities of hazardous chemicals. The SHSO will make copies of these MSDSs available to any subcontractors (i.e. drillers, excavators) on this project. 4.2.2 Site Constituents At this time, the site is not considered to have chemical constituents that may pose a hazard to those working on the site; however, site activities, site investigations or other events may potentially expose chemical hazards. If contamination is suspected that may expose workers to hazardous chemicals at the site, work activities will be halted. Contaminants of concern at the site include toluene, heavy metals and by-products of the Vanillin process including some mineral oils. Previous investigations of a section of the facility, performed by others have identified the presence of toluene, food grade mineral oil, dissolved copper, PCBs, PAHs, and a high pH in soils and groundwater. Copper WISHA PEL =0.1 mg/m3 (fume) TLV = 0.2 mg/m3 (fume) PEL1.0 mg/m3 (dust) 1.0 mg/m3 (dust) Chronic human intoxication rarely occurs from copper exposure. Ingestion exposure of large doses of copper is limited by its emetic effect. Inhalation of copper fume from welding processes has produced upper respiratory tract irritation and metal fume fever in exposed workers. Copper is also an essential element in human nutrition; normal intake is approximately 2 mg/day. Adverse effects have been demonstrated only at high exposure levels, and low levels of exposure are unlikely to be of concern. Toluene CAL /OSHA PEL = 50 PPM; STEL =' 150 PPM Fed/OSHA PEL = 200 ppm WISHA PEL = 100 PPM TLV = 50 ppm "skin" H:'.RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 10 REL = 100 ppm Toluene is a central nervous system depressant. Symptoms include headache, nausea, dizziness and fatigue, but such symptoms typically do not occur at exposures below 200 ppm. Repeated and prolonged contact with liquid toluene may cause drying of the skin and dermatitis. Mild, transitory eye irritation may be experienced with exposure to vapors above 200 ppm. Toluene is not considered carcinogenic. Toluene's mean odor threshold is 3 ppm, which gives it good warning properties. Toluene's ionization potential (IP) is 8.82 eV, and its vapor pressure is 22 mm Hg. Toluene is known to the State of California to cause reproductive toxicity under the criteria of Proposition 65. Corrosives (Acids and Caustics) Corrosives are low pH (acids) or high pH (caustics or alkalis) substances that, by direct chemical action, are injurious to body tissue or can damage metal. Corrosive injury may be minor (irritation) or severe (causing burns or blindness). Caustic bums can be particularly dangerous because strong alkalis gelatinize tissue. Initial contact may not be painful, but prolonged contact and/or high concentrations can cause deep penetrating burns. The effects of solid corrosives (such as dusts) are largely dependent on their solubility in skin, moisture, and duration of contact. Eye, face, and skin protection should be worn whenever there may be contact with materials suspected of being contaminated with caustics. Nitric Acid WISHA/OSHA PEL /TLV/REL = 2 ppm STEL = 4 ppm Nitric acid is an extremely corrosive liquid and may cause severe burns, ulcers, and necrosis of the skin, mucous membranes, and eye tissues. Continued exposure to the vapor and mist of nitric acid may result in chronic bronchitis, with more severe exposure leading to chemical pneumonitis. 4.3 BIOLOGICAL HAZARDS Biological hazards may be encountered during field activities. Common biological hazards include: ticks, poison plants, mosquitoes, and snakes. Workers will be aware of the biological hazards that may be present on the site and the symptoms associated with exposure to these hazards. Exposure to biological hazards will be minimized through the use of personal protective equipment and proper hygiene. Personal protective equipment to be used may include: gloves, long sleeved shirts and long pants, and insect repellent. Workers will wear gloves for work handling wastewater, and face - shields where there is the potential for splash hazards. Workers will be instructed to wash their hands before they eat, smoke or leave the site. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver- 01.doc Health and Safety Plan Page 11 4.4 PHYSICAL HAZARDS Potential non - chemical hazards associated with this site are described below. 4.4.1 Slips, Trips, and Falls Slips, trips, and falls are a potential source of trauma because of steep terrain, uneven ground, wet conditions or sampling equipment not properly stored in staging areas. Care should be taken to ensure proper footing and hand holds. The sampling area should be kept uncluttered and good housekeeping should be enforced. Construction debris, scrap metal, and other materials that pose puncture hazards should be picked up and disposed of properly. Proper footwear and careful attention to the terrain and the immediate vicinity are necessary to prevent injuries. Workers will be required to use fall protection if working at heights greater than 10 feet in accordance with the Washington State Fall Protection Standard for Construction Work. There is the potential for workers to fall into the excavation created for the soil - bentonite slurry wall. To ensure workers do not fall into the excavation, warning tape or other means of identification will be utilized to alert workers they are near the excavation. Workers will not be allowed to cross the excavation except through means of designated personnel crossings. The use of rescue gear, emergency response scenarios and the buddy system will be discussed in the safety pre - briefing prior to initiation of site activities. In addition, 1/2 mask respirators with HEPAIP100 cartridges will be used during work with dry bentonite materials if dust exposures cannot be controlled through other means. 4.4.2 Skeletal - Musculature Injury Field activities may require some lifting of heavy objects (ex. air compressor). No one is to attempt to lift large or heavy objects without assistance. The field task manager will ensure that appropriate equipment is available when it is necessary to move heavy equipment or objects. The following guidelines will be followed whenever lifting equipment such as, portable generators, compressors, coolers filled with samples, objects that are an odd size or shape or that weigh over 40 pounds. • Portable generators and/or compressors will be lifted using a two- person lift. • When moving heavy objects such as drums or containers, use a dolly or other means of assistance. • Plan the lift. If lifting a heavy object, plan the route and where to place the object. In addition, plan communication signals to be used (i.e., "1,2,3 lift "). • Wear sturdy shoes in good condition that supply traction when performing lifts. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F -HASP \RedevelopmentHASP- ver- 01.doc Health and Safety Plan Page 12 4.4.3 Noise • Keep your back straight and head aligned during the lift and use your legs to lift the load. Do not twist or bend from the waist. Regulations governing hearing conservation are provided in 29CFR 1910.95. Engineering controls will be used to dampen excessive noise at or above Occupational Safety and Health Administration (OSHA) Action Level of 85 dBa. Hearing protection, such as ear plugs, are required when working near an heavy equipment or speech is difficult to distinguish using a normal speaking voice. All Geomatrix field personnel should be participating in a Hearing Conservation Program and have had baseline exams and where appropriate, annual audiograms. 4.4.4 Hand Tools Eye injuries, puncture wounds, cuts, or lacerations could result from use of hand tools while collecting samples or repairing equipment. Tools should be in good condition and the right tool should be selected for the job. Safety glasses with side shields or safety goggles should be worn whenever projectiles are a potential problem. Loose clothes or jewelry will not be worn while operating hand tools. Steel -toed shoes should be worn when there is any risk that something could fall on the foot. Tools should be stored safely, with sharp edges protected. Screwdrivers should not be used as chisels, because their tips could break or fly off. The head could fly off a hammer with a loose or cracked wooden handle. Impact tools, such as chisels or wedges, with mushroomed heads might shatter on impact, sending sharp fragments flying. Knives, saw blades, and scissors must be sharp. 4.4.5 Heavy Equipment Operation of heavy equipment during site activities presents potential physical hazards to personnel. The following precautions must be observed whenever heavy equipment is in use: Personal protective equipment (PPE) such as steel -toed shoes, safety glasses or goggles, and hard hats must be worn whenever such equipment is present. Personnel must at all times be aware of the location and operation of heavy equipment, and take precautions to avoid getting the way of its operation. Never assume that the equipment operator sees you; make eye contact and use hand signals to inform the operator of your intent, particularly if you intend to work near or approach the equipment. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP\Redeve lopmentHASP- ver- O1.doc Health and Safety Plan Page 13 Traffic safety vests are required for Geomatrix personnel working near mobile heavy equipment, such as backhoes and other excavators. Never walk directly in back of or to the side of, heavy equipment without the operator's acknowledgment. When an equipment operator must operate in tight quarters, the equipment subcontractor should provide a person to assist in guiding the operator's movements. Keep all non - essential personnel out of the work area. 4.4.6 Underground and Aboveground Utilities The Site Manager or SHSO is responsible to ensure that underground utilities are located prior to the commencement of any subsurface (> 0.3 meters (1 ft.) activities. Resources include site plans, utility companies, and regional utility locating services. The proper utility company personnel shall certify in writing to the Site Manager or SHSO the deactivation of underground utilities, and the certification retained in the project files. Excavation, drilling, crane, or similar operations adjacent to overhead lines shall not be initiated until operations are coordinated with the utility officials. Operations adjacent to overhead lines are prohibited unless one of the following conditions is satisfied: Power has been shut off and positive means (e.g. lockoutltagout) have been taken to prevent lines from being energized. Wherever possible, the Geomatrix SHSO will observe power shut off and place a lock and tag on the switch. In all cases utility company personnel shall certify in writing to the Site Manager or SHSO the deactivation of overhead utilities, and the certification retained in the project files. The Site Manager or SHSO must also attempt to verify power shut off by checking that power is no longer available to the affected building or equipment. Equipment, or any part of the equipment, cannot come within the following minimum clearance from energized overhead lines (note — some states may have more stringent requirements): Power Lines Nominal System (kv) Minimum Required Clearance 0 -50 10 feet 51- 200 15 feet 201 -300 20 feet 301 -500 25 feet 501 -750 35 feet 751 -1000 45 feet H:\RCI - RP Site Redevelopment \Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 14 4.4.7 Trenching and Excavation All Geomatrix personnel are prohibited from entering a trench or excavation until it has been inspected by a competent person in accordance with 29 CFR 1926.650 -651 or the State Equivalent. If personnel are required to enter a trench or excavation that is deeper than four feet, the following provisions must be provided prior to entry by the contractor who created the excavation: If hazardous atmospheres are suspected, any trench or excavation more than four feet deep must be monitored. Adequate shoring, sloping, or benching techniques must be employed. Adequate means of employee access and egress must be utilized. The contractor's trained, competent person must inspect the trench or excavation on a daily basis, before work commences and on an as- needed basis throughout the day. A copy of the Fed -OSHA Excavation Standard can be obtained from the HSM. All provisions of this regulation must be complied with when working in a trench or excavation. Please note that state equivalents may be more stringent. 4.4.8 Heat Stress Field personnel involved in work tasks at each site may be susceptible to heat stress during periods of elevated ambient temperatures or humidity, or during the performance of strenuous activities, particularly if impervious protective clothing is worn. Personnel will be monitored for early signs of heat stress, whenever ambient temperatures reach or exceed 85 °F. Whenever impervious clothing (e.g., Tyvek) is worn, personnel will be monitored when temperatures exceed 70 °F. Worker rotation schedules should be established as necessary. Drinking water and electrolyte beverages will be available at each work site and personnel will be encouraged to drink sufficient fluids to prevent salt loss and dehydration. Personnel should be cognizant of the early signs of heat stress and the necessary treatment procedures. 4.4.9 Cold Weather Stress (Hypothermia and Frostbite) Care must be taken to limit cold exposure by providing proper protective clothing, access to warm shelter, and a temperature- dependent work regimen limiting periods of outdoor activity, if necessary. Protection against cold stress should be initiated when temperatures drop below 45 4.4.10 Electrical Safety Ground fault circuit interrupters (GFCI) shall be used on all extension cords. All extension cords shall have a non - current carrying grounding conductor, and shall be equipped with strain relief. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 15 Cords with damaged insulation, plugs, or sockets shall not be used. Damaged extension cords are not to be repaired and shall be taken out of service. The SHSO is responsible for performing periodic inspections on portable extension cords and GFCIs. Extension cords that are used in the work area are to be inspected weekly. The SHSO is responsible for establishing a system of unique identifiers for extension cords and GFCIs, and a means of denoting that the system passed the periodic inspection. All portable tools shall be grounded or fabricated of approved, double insulated construction. Personnel are required to lockout and tagout any equipment (e.g. electrical, pumps, blowers) on which they will be performing any kind of maintenance or work which could result in an injury in the event of an unexpected startup. Warning signs will be posted on all equipment requiring lockout. "Lockout" involves physically locking out the energy source(s) to a piece of equipment scheduled for maintenance or repair to prevent an accidental movement or startup of the equipment. The lockout rule applies to almost every piece of utilized equipment. The exception to this is cord -and -plug equipment if it is unplugged and the plug is in the control of the worker at all times, and if there are no other sources of energy to the equipment. The types of work activities which could require Lockout/Tagout procedures include installing a piece of equipment, modifying a piece of equipment, and adjusting, maintaining, or servicing a piece of equipment in a manner in which an unexpected movement or startup of the equipment could cause injury. The types of energy that may need to be addressed include electrical and mechanical. Where a piece of equipment has more than a single source or type of energy, each must be addressed. The lockout hardware used is to be durable for the type of use it will receive, identifiable as to its purpose and owner, and individually assigned so that only the worker using the lock has the key. Workers who will be conducting work which will involve Lockout/Tagout procedures are to notify any other workers who may be affected by the Lockout. No worker is to attempt to remove the lock of another and restart locked and tagged out machinery. Only authorized and trained personnel will perform lockout and tagout. Training will be provided by the SHSO during the startup safety briefing. Authorized personnel will receive training during site safety briefing on what equipment requires lockout/tagout and proper lockout and tagout procedures. 4.4.11 Machine Guarding Remediation equipment such as blowers present hazards from nip points and rotating parts. Equipment must be provided with machine guarding (e.g. cages, shields) to protect employees. This guarding must be designed to prevent the operator from having any part of his body in the danger zone where it could be caught or struck by moving parts during the operating cycle. Machine guarding must not be removed for any reason except during necessary maintenance and repair. Proper lockout and tagout procedures must be followed to prevent the accidental energizing of equipment during maintenance and repair. Machine guards must be put back in H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc • T ask CChem: s ' Hzds.

Typical activities would involve mobilization, site preparation, demolition, earthwork, handling of waste, and the installation of a grownwater recover and monitoring system. Tasks involving the potential for contact with contaminated soils and wastewater may include all of the above. High — Exposure likely more than 50% of the time Med — Exposure likely 10 -50% of the time Low — Exposure likely less than 10% of the time n/a — Exposure not anticipated 5.0 HAZARD CONTROL MEASURES Hazard control measures are the primary steps taken to reduce the potential for accidents or exposures. All appropriate hazard control steps must be taken. Hazard control measures include Personal Protective Equipment (PPE), administrative controls, and air monitoring. 5.1 PERSONAL PROTECTIVE EQUIPMENT 5.1.1 General Personal Protective Equipment Level D PPE is expected to provide adequate protection for most tasks involving construction oversight and inspection. Level D PPE requirements are as follows: • Safety glasses with side shields or goggles are to be worn when working near the drill rig and/or handling chemicals (ex. preserving bottles); • A hard hat is to be worn when overhead hazards exist; • Work clothing; H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 17 • Steel -toed boots are to be worn when in any area where equipment, drums, or other heavy items could crush feet; • Ear plugs are required when working near noise in excess of 85 dBA or speech is difficult to distinguish using a normal speaking voice; and • Work gloves as needed for working with sharp items or contaminated materials. The next level of protection would be an upgrade to Modified Level D PPE as determined necessary by the SHSO. Modified Level D PPE requirements are as follows: • Safety glasses with side shields or goggles are to be worn when working near the drill rig and/or handling chemicals (ex. preserving bottles); • A hard hat is to be worn when overhead hazards exist; • A Tyvek protective coverall is to be worn within contaminated areas; • Steel -toed boots are to be worn when working in any area where equipment, drums, or other heavy items could crush feet; • Ear plugs are required when working in an area in excess of 85 dBA or speech is difficult to distinguish using a normal speaking voice; and • Latex gloves are to be worn during sample collection or work with wastewater. • A face shield may be added to prevent splash hazards associated with wastewater. PPE for Confined Space Entry may be encountered. Confined Space Entry will be performed in accordance with Geomatrix, federal, state and local requirements. 5.2 ADMINISTRATIVE CONTROLS The following administrative controls will be used throughout the duration of field activities: • All site personnel will read, understand, and sign the HSP prior to project site activities; • The HSP must be present on site and will be followed by all site personnel; • Hands and face must be washed when leaving the work area and before engaging in any other activity, especially eating, drinking, or smoking; H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc Health and Safety Plan Page 18 • Protective clothing and equipment will be worn at the work site at the protective level specified in this HSP or by the SHSO; • All personnel will be trained in site - specific emergency procedures, including knowing the location of emergency telephone numbers and hospital route maps; • Personnel must use the "buddy system" as deemed necessary by the SHSO. Under no circumstances will employees work alone on site; • Safety briefings will be held weekly, or as needed, by the SHSO. Appropriate records will be kept of all meetings and decisions, which will be recorded in the field logbook; • Personnel will be instructed to record all of their activities and responsibilities in their field logbooks; • Possession or use of alcoholic beverages or drugs on site is prohibited. Employees may not report for work or perform duties while under the influence of intoxicants or drugs. Excessive consumption of alcoholic beverages is discouraged during off -duty hours because of the incompatibility of alcoholic beverages and site hazards; and • All personnel must immediately bring to the attention of the field supervisor, SHSO, or other supervisory personnel any condition, practice, or circumstance they believe is unsafe. 5.2.1 Site Preparation To eliminate or control physical hazards encountered on site, use existing roadways rather than crossing unpaved areas, if possible. This practice will help transport personnel, materials, and equipment safely. 5.3 SITE SECURITY Site security at sites will be necessary to limit site access to authorized personnel only. Site security is the responsibility of the SC /SHSO or designee. Lock equipment within a fence or in a portable storage unit or secure off site during off - hours. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F -HASP \RedevelopmentHASP- ver- 01.doc Health and Safety Plan Page 19 5.4 SITE COMMUNICATIONS Two sets of communication systems will be established and checked daily prior to the start of work: • Internal communication among personnel on site will consist of hand signals; and • External communication (telephone and radio) between on -site and off -site personnel will be established by the SC /SHSO. The SC /SHSO will have a radio or cellular phone or will locate the nearest available phone in order to contact essential personnel in the event of emergency. 5.4.1 Tailgate Safety Meetings Tailgate safety meeting will be conducted upon the initiation of each discrete type of task. These meetings shall be conducted by the SHSO and will cover specific health and safety issues, site activities, changes in site conditions and a review of topics to be covered in the initial health and safety meeting as they apply to task- specific activities. Issues addressed in the tailgate meeting will be documented in the field logbook. Documentation of who attended the tailgate meeting shall be retained by the HSM with copies forwarded to the project records. 5.5 DECONTAMINATION PROCEDURES 5.5.1 General Decontamination Procedures If the monitoring instrument readings reach the Action Level in the OBZ or visible airborne dust indicate respirator use, the following steps will be followed whenever personnel leave the Exclusion Zone or work area: 1. Remove all equipment, sample containers, and notes from EZ and place in the CRZ. 2. Scrub boots with a stiff - bristled brush, wash with a decontamination solution, and then rinse with water. Washtubs and chairs will be provided. 3. Remove outer gloves (and boot covers, if used). 4. Remove Tyvek coverall; discard in provided container. 5. Remove hardhat; wash outer layer, rinse. 6. Remove eye protection. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver- 01.doc Health and Safety Plan Page 20 7. Remove hearing protection. 8. Remove inner gloves. 9. Thoroughly wash hands, neck, and face. 10. Proceed to SZ. 11. Redress in street clothes and exit. The decontamination area will be covered with plastic sheeting, which will be replaced when tom or heavily soiled, and at the end of each shift. Each worker will be responsible for cleaning, sanitizing, and storing their own respirator in accordance with manufacturer's guidance (i.e., washing in warm water and detergent or sanitizing solution, air drying, and storing in a plastic storage bag). Cartridges will be changed in accordance with the Company Health and Safety Program. All investigation- derived wastes (IDW) will be segregated into one of three categories: • Wastewater (includes well purge water and decontamination water) • Soil (includes drill cuttings and sediment from decontamination containers) • Solids (includes disposable PPE and sampling equipment) Each waste type will be placed in an appropriate container such as an open- topped, 550 gallon drum. Labels identifying the contents will be placed on each container. Waste containers will be stored on site pending laboratory analysis. Ultimate disposal will be coordinated with the PM and in accordance with relevant regulations. 5.5.2 Sanitation Potable water will be made available at the site, either from a pressurized source or commercially available bottled water. Drinking cups will be supplied so personnel will neither drink directly from the source of water nor have to share drinking cups. Sources of non - potable water shall be clearly labeled as such. Unless toilet facilities are available on site or transportation is readily available to transport personnel to nearby (within 5 minutes) toilet facilities, portable toilet facilities, such as chemical toilets, will be provided on site. Washing facilities will be provided on site, and will be located in the decontamination area or the support area. Soap, clean water, wash basins, and single -use towels will be available for personnel use. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver -01.doc 1 1 5.5.3 Decontamination — Medical Emergencies Health and Safety Plan Page 21 ' In the event of physical injury or other serious medical concerns, immediate first aid is to be administered in lieu of further decontamination efforts. 5.5.4 Decontamination of Tools When all work activities have been completed, contaminated tools will be either appropriately decontaminated or properly disposed of as hazardous waste. Tools that can be decontaminated are constructed of non - porous, non - absorbent materials. Decontaminate tools (shovels, auger flights, etc.) by brushing them with a decontamination solution (e.g., Alconox and water) and rinsing with water. A high- pressure steam cleaner may also be used for decontamination. All visible particles are to be removed before the tool is considered clean. All waste and spent decontamination solutions will be properly contained. Any tool, or part of a tool, that is made of a porous /absorbent material will be discarded and disposed of as a hazardous waste if it cannot be properly decontaminated. 5.6 MONITORING EQUIPMENT The use of monitoring equipment is not anticipated due to the semi - volatile nature of oil. If site conditions change or odors are noted that cause concern, a photoionization detector may be used to determine airborne concentrations to total hydrocarbons. The following may be utilized: Organic Vapor Analyzer, Microtip, Hnu, Organic Vapor Monitor, MiniRAE PJD ' (0) The monitoring equipment must be calibrated in accordance with the manufacturer's instructions. In addition, the results of daily instrument calibrations shall be logged in the field logbook, or on a Daily Instrument Calibration Check Sheet. 1 1 1 1 1 1 H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP- ver- 01.doc „Analyzer Reading'.

(RPI) facility located in Tukwila, Washington (the site). The purpose of this Construction Stormwater Pollution Prevention Plan (SWPPP) is to identify the procedures that will be implemented at the site to prevent adverse stormwater impacts from these construction activities, The Stormwater Management Manual, for Western Washington, Volume II (Ecology, February 2005) was used to prepare this SWPPP., Section 2.0 provides a site description and project background. Section 3.0 describes the existing stormwater drainage system at the site. Section 4.0 describes the best management practices (BMPs) that will be implemented for stormwater protection and erosion and sediment control. 2.0 SITE DESCRIPTION AND PROJECT BACKGROUND 2.1 SITE DESCRIPTION AND PROJECT BACKGROUND The former RPI facility is located in southwestern King County, City of Tukwila, Washington, in Township 24 North, Range 4 East, Section 33, Willamette Meridian at 9229 East Marginal Way South, The site is flat industrially -zoned land bordering the east bank of the Duwamish Waterway and the north bank of Slip 6. The area surrounding the facility is also zoned for heavy industrial use_ Kenworth Truck Company is located to the north, the Boeing Developmental Center is located to the south, and East Marginal Way and the King County International Airport lie to the east. The property covers about 21.5 acres, 19.5 of which are onshore and 2 of which are offshore intertidal areas in the Duwamish Waterway. Figure 1 shows the location of the former RPI facility, and Figure 2 is a site layout map. There are currently no manufacturing activities ongoing at the site. The facility closed in 1991, at which time process equipment (mostly tanks) and several of the buildings were dismantled or removed The property is surrounded by fencing and secured gates. The site will be undergoing redevelopment activities in the near future, including installation of new electrical service, subsurface trenching, groundwater extraction pipeline installation, and building construction. H;\8769 005 - SWPPP for Demo\GMX SWPPP for CP Draft trenching only doc 1 The western portion of the site is being addressed as part of a Resource Conservation and Recovery Act (RCRA) interim action. The interim action consists of a low permeability barrier wall, three groundwater extraction wells, and a groundwater pretreatment system. Groundwater is extracted from within the barrier wall, pretreated, and then discharged to the local sanitary sewer system. The existing groundwater pre - treatment system will be relocated as part of the redevelopment of the site. Other activities that will be conducted on the western portion include trenching and installation of new electrical service for the relocated groundwater pretreatment, and construction of the new groundwater pretreatment building. The eastern half of the property, as shown on Figure 2, is outside the area of the RCRA interim action; however, planned redevelopment activities on the western portion of the property will require use of the eastern half of the site for routing of electrical service. Figure 2 includes the proposed electrical and pipeline trench locations, the new location of the groundwater pretreatment system, the current structure locations, and the location of catch basins and silt fencing. 3.0 EXISTING SITE DRAINAGE SYSTEM The site is relatively flat and mostly paved or gravel- surfaced, with little if any surface vegetation. There is an existing stormwater drainage system at the site, which consists of a system of stormwater "drop" catch basins and associated underground conveyance piping. Stomiwater at the site is currently discharged through two outfalls to Slip 6 and the Duwamish Waterway. One outfall, which is known as the King County Outfall, discharges stormwater from the site to the eastern end of Slip 6. The second outfall is located near the northwest comer of the site and discharges stormwater from the western side of the site to the Duwamish Waterway. All of the other historic outfalls at the site have been abandoned and/or plugged. It does not appear that the site receives stormwater runoff from areas outside the facility boundary. 4.0 STORMWATER MANAGEMENT APPROACH The Sformwater Management Manzral for Western Washington, Volume II identifies 12 key elements that should be addressed in a Construction SWPPP, as listed below: • Mark Clearing Limits_ • Establish Construction Access. 11:18769 005 - SWPPP for Dccno \GMX SWPPP for CP Draft trenching only doe 2 • Control Flow Rates. • Install Sediment Controls. • Stabilize Soils. • Protect Slopes. • Protect Drain Inlets. • Stabilize Channels and Outlets. • Control Pollutants. • Control De- Watering. • Maintain Best Management Practices (BMPs). • Manage the Project. Each of these items is addressed in the sections below. 4.1 MARK CLEARING LINIITS The site is largely clear of significant vegetation. Site clearing and grubbing will be limited to miscellaneous surface vegetation removal as required for trenching along the electrical and groundwater recovery pipe locations. Most of the vegetation on -site near areas of construction is limited to invasive weed species such as Himalayan blackberries and butterfly bushes. Barrier tape, temporary construction fencing, and/or portable barriers will be used to define the active work zones and control access routes in the immediate area. As the trenching activities progress, barriers will be adjusted to accommodate equipment operations. 4.2 ESTABLISH CONSTRUCTION ACCESS A single construction access /exit point will be established for the site. The site is paved or covered with gravel so sediment will not be transferred on the wheels of the construction equipment. Any sediment on the equipment will be removed before the equipment is mobilized off -site. 4.3 CONTROL FLOW RATES Increases in the volume, velocity, and peak flow rate of stormwater runoff are not expected to occur as a result of the construction activities. As mentioned in Section 4.1, the site is largely clear of significant vegetation, and the amount of impervious surface will not be increased. Therefore, BMPs for controlling flow rates are not required. H:18769 005 . SWPPP for Dcmo\GMX SWPPP for CP Drn0 trenching only doc 3 4.4 INSTALL SEDIMENT CONTROLS The trenching for the electrical service is anticipated to occur prior to October 1 so the soil excavated for this trench can remain exposed and uncovered for up to seven days. The installation of the new underground piping system for the relocated groundwater pretreatment area is expected to occur after October 0, so soils excavated from the trenches can remain exposed and uncovered for a maximum of two days. If necessary, plastic sheeting will be used to cover the excavated soil piles before holiday or weekends depending on the weather forecast. The design and installation specifications for sediment control measures will meet the requirements specified in BMP C123 (Plastic Covering), and BMP C233 (Silt Fence) of the Stormwaler Management Manual for Western Washington, Volume II (February 2005) (see Appendix A). Figure 4 shows the planned erosion and sediment control measures. Following are the maintenance requirements for plastic covers: • Torn sheets must be replaced and open seams repaired. • If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. •. When the plastic is no longer needed, it shall be completely removed. Following are the maintenance requirements for silt fences: • Any damage will be repaired immediately. • If concentrated flows are evident uphill of the fence, they must be intercepted and conveyed to a sediment trap. • The uphill side of the fence will be checked for signs of the fence clogging and acting as a barrier to flow, thus causing channelization of flows parallel to the fence. If this occurs, the fence will be replaced, or the trapped sediment will be removed. • Sediment deposits will either be removed when the deposit reaches approximately one -third height of the silt fence, or a second silt fence will be installed. • If the filter fabric (geotextile) has deteriorated due to ultraviolet breakdown, it will be replaced. H_ \6769 005 - SWPPP for Demo ■GMX SWPPP for CP Droll trenching onlp doe 4 4.5 STABILIZE SOILS AND OTHER MATERIALS Once all site excavation and stockpile activities have been completed, the exposed soils at the site will need to be restored. The design and installation specifications for the plastic covering will meet the requirements specified in BMP C123 (Plastic Covering) of the Storrnwater Management Manual for Western Washington, Volume II (February 2005) (see Appendix A). Site restoration will include the following: • Repair and replacement of concrete and asphalt surfaces disturbed by construction activities • Filling, regrading, or repair of heavily rutted or scarred surface soil to pre - construction conditions or better • Inspection of catch basins, manholes, and permanent storm water controls at the site, and the removal and disposal of any accumulated solids • Final grading and stabilization of surface areas disturbed by construction, or other protective measures to prevent erosion and sedimentation • Removal and relocation of temporary protective actions for existing work and return of surface equipment, materials, or other features their original location Following are the maintenance requirements for plastic covering: • Torn sheets must be replaced and open seams repaired. • If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. • When the plastic is no longer needed, it shall be completely removed. 4.6 PROTECT SLOPES Cut and fill slopes will not be required for this project. Therefore, BMPs for slope protection are not required. 4.7 PROTECT DRAIN INLETS Catch basin inserts will be placed in all catch basins located within the main perimeter of the construction site to prevent sediment and construction- related petroleum products from entering the stormwater drainage system. Catch basins within the active work areas will be isolated by H:18769 005 - SWPPP for Dcmo1GNDC SWPPP for CP Draft vcociiing only doc 5 capping the inlet grates, constructing small berms around the catch basins, or placing hay bales or sandbags around the catch basins. The design and installation specifications for storm drain inlet protection measures will meet the requirements specified in BMP C220 (Storm Drain Inlet Protection) of the Stornnvater Management Manual for Western Washington, Volume II (February 2005) (see Appendix A). Following are the maintenance requirements for storm drain inlet protection: • Catch basin filters will be inspected frequently, especially after storm events. If the insert becomes clogged, it will be cleaned or replaced. • For systems using stone filters, if the stone filter becomes clogged with sediment, the stones will be pulled away from the inlet and cleaned or replaced. If cleaning the stones is not feasible, the stones will be replaced with new stones. Sediment must not be washed into storm drains while cleaning. 4.8 STABILIZE CHANNELS AND OUTLETS Temporary onsite conveyance channels are not required for this project. Therefore, BMPs for stabilizing channels and outlets are not required,. 4.9 CONTROL POLLUTANTS Pollutants that could be generated during construction include: • Sediments from excavation or stockpiling activities • Spills of fuels or oil during equipment maintenance Catch basins within the active work areas will be isolated by capping the inlet grates with polyethylene sheeting and gravel or by constructing small berms around the catch basins. The following procedures will be implemented to prevent spills during equipment fueling and maintenance operations: • The fuel vendor tanker truck driver as well as an onsite construction worker will be present during all fuel transfers. • The amount of fuel to be added to equipment should be determined prior to starting fueling operations. • Oil and fuel absorbent material will be readily available during all oil and fuel handling and transfer operations. H:18769 005 - SWPPP for Dcmo1GMX SWPPP for CP Draft trenching only doc 6 • Spill buckets will be used during all fuel and oil transfers to catch any drips or leaks during fueling and maintenance operations. • Storm drains (catch basins) in the immediate vicinity of the equipment tank being filled or equipment maintenance area will be covered with a mat, plug, or other suitable device during fueling and maintenance operations. This process will prevent the flow of product into the drain in case of a leak or spill. If a spill occurs, storm drain covers will not be removed until the spilled material and any associated contaminated soil has been removed. • When transferring petroleum products, connections and transfer points will be carefully monitored for leaks. • Equipment fuel tanks will never be topped off completely. Adequate headspace at the top of the tank will be left to allow for product expansion. • Equipment receiving fuel and oil will be carefully checked prior to and during delivery to ensure that there are no leaks or open drain valves. A spill kit will be maintained onsite to handle potential fuel or oil leaks /spills from construction equipment. The design and installation specifications for storm drain inlet protection measures will meet the requirements specified in BMP C220 (Storm Drain Inlet Protection) of the Stornrivater- Management Manual for Western Washington, Volume II (February 2005) (see Appendix A). While it is not anticipated that a large quantity of petroleum products will be stored on -site during operations, all such products will be transferred and stored in accordance with BMP153 (Material Delivery, Storage, and Containment) of the Stornnvater Managernent Manual for Western Washington, Volume II (February 2005) (see Appendix A). 4.10 CONTROL DE- WATERING Dewatering is not anticipated to be an issue at this site since dewatering will not be required as part of the anticipated construction activities. 4.11 MAINTAIN BEST MANAGEMENT PRACTICES Erosion and sediment control BMPs will be maintained and repaired as needed to ensure continued performance of their intended function. Maintenance and repair will be conducted in accordance with the maintenance requirements specified in the preceding sections. Erosion and H: \8769 005 - SWPPP for Demo \GMX SWPPP for CP Draft trenching only doc 7 sediment control BMPs will be inspected weekly or after a storm event (which may be daily during the wet season from October 1 through April 30). Trapped sediment from the erosion and sediment control measures will be removed and transported to the western part of the site pending future redevelopment activities. Any sediments will be stockpiled and covered with plastic as described in BMP C123 (Plastic Covering) of the Stormwater Management Manual for Western Washington, Volume II (February 2005) (see Appendix A). 4.12 MANAGE THE PROJECT The erosion and sediment control measures described in this SWPPP will be constructed and in operation prior to the start of any construction activity. These measures will be maintained for the duration of the project and until permanent stabilization is established.. All temporary erosion and sediment control measures described in this SWPPP will be removed upon project completion. This SWPPP will be maintained onsite or within reasonable access to the site. The SWPPP will be modified whenever there is a significant change in the design, construction, operation, or maintenance of any BMP. 4.13 SCHEDULE The trenching for the installation of the electrical service is scheduled to begin on September 27, 2005, and is anticipated to be completed by October 1, 2005. Trenching for the groundwater extraction piping is anticipated to occur after October I, 2005 for approximately a two -week period.

Conditions of • Plastic covering may be used on disturbed areas that require cover Use measures for less than 30 days, except as stated below. • Plastic is particularly useful for protecting cut and fill slopes and stockpiles. Note: The relatively rapid breakdown of most polyethylene sheeting makes it unsuitable for long -term (greater than six months) applications. • Clear plastic sheeting can be used over newly - seeded areas to create a greenhouse effect and encourage grass growth if the hydmseed was installed too late in the season to establish 75 percent grass cover, or if the wet season started earlier than normal. Clear plastic should not be used for this purpose during the summer months because the resulting high temperatures can kill the grass, • Due to rapid runoff caused by plastic sheeting, this method shall not be used upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. • While plastic is inexpensive to purchase, the added cost of installation, maintenance, removal, and disposal make this an expensive material, up to $ I50 -2.00 per square yard. • Whenever plastic is used to protect slopes, water collection measures must be installed at the base of the slope. These measures include plastic- covered berms, channels, and pipes used to covey clean rainwater away from bare soil and disturbed areas. At no time is clean runoff from a plastic covered slope to be mixed with dirty runoff from a project. • Other uses for plastic include: 1. Temporary ditch liner, 2. Pond liner in temporary sediment pond; 3. Liner for bermed temporary fuel storage area if plastic is not reactive to the type of fuel being stored; 4. Emergency slope protection during heavy rains; and, 5. Temporary drainpipe ("elephant trunk") used to direct water. 4-26 Volume 11— Construction Stormwater Pollution Prevention February 2005 Design and • Plastic slope cover must be installed as follows: Installation 1. Run plastic up and down slope, not across slope; Specifications 2. Plastic may be installed perpendicular to a slope if the slope length is less than 10 feet; 3. Minimum of 8 -inch overlap at seams; 4. On long or wide slopes, or slopes subject to wind, all seams should be taped; 5. Place plastic into a small (12-inch wide by 6 -inch deep) slot trench at the top of the slope and backfill with soil to keep water from flowing underneath; 6. Place sand filled burlap or geotextile bags every 3 to 6 feet along seams and pound a wooden stake through each to hold them in place; 7. Inspect plastic for rips, tears, and open seams regularly and repair immediately. This prevents high velocity runoff from contacting bare soil which causes extreme erosion; 8. Sandbags may be lowered into place tied to ropes. However, all sandbags must be staked in place. • Plastic sheeting shall have a minimum thickness of 0.06 millimeters. • If erosion at the toe of a slope is Iikely, a gravel berm, riprap, or other suitable protection shall be installed at the toe of the slope in order to reduce the velocity of runoff. Maintenance • Torn sheets must be replaced and open seams repaired. Standards • If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. • When the plastic is no longer needed, it shall be completely removed. • Dispose of old tires appropriately. February 2005 Volume II — Construction Stormwater Pollution Prevention 4-27 BMP C153: Material Delivery, Storage and Containment Purpose Prevent, reduce, or eliminate the discharge of pollutants from material delivery and storage to the stormwater system or watercourses by minimizing the storage of hazardous materials onsite, storing materials in a designated area, and installing secondary containment. Conditions of Use These procedures are suitable for use at all construction sites with delivery and storage of the following materials: • Petroleum products such as fuel, oil and grease • Soil stabilizers and binders (e.g. Polyacrylamide) • Fertilizers, pesticides and herbicides • Detergents • Asphalt and concrete compounds Design and Installation Specifications February 2005 • Hazardous chemicals such as acids, lime, adhesives, paints, solvents and curing compounds • Any other material that may be detrimental if released to the environment The following steps should be taken to minimize risk: • Temporary storage area should be located away from vehicular traffic, near the construction enlrance(s), and away from waterways or storm drains. • Material Safety Data Sheets (MSDS) should be supplied for all materials stored. Chemicals should be kept in their original labeled containers. • Hazardous material storage on -site should be minimized. • Hazardous materials should be handled as infrequently as possible. • During the wet weather season (Oct 1— April 30), consider storing materials in a covered area • Materials should be stored in secondary containments, such as earthen dike, horse trough, or even a children's wading pool for non- reactive materials such as detergents, oil, grease, and paints. Small amounts of material may be secondarily contained in "bus boy" trays or concrete mixing trays. • Do not store chemicals, drums, or bagged materials directly on the ground. Place these items on a pallet and, when possible, in secondary containment. Volume 11— Construction Soormwater Pollution Prevention 4-45 • If drums must be kept uncovered, store them at a slight angle to reduce ponding of rainwater on the lids to reduce corrosion. Domed plastic covers are inexpensive and snap to the top of drums, preventing water from collecting. Material Storage Areas and Secondary Containment Practices: • Liquids, petroleum products, and substances listed in 40 CFR Parts 110, 117, or302 shall be stored in approved containers and drums and shall not be overfilled. Containers and drums shall be stored in temporary secondary containment facilities. • Temporary secondary containment facilities shall provide for a spill containment volume able to contain precipitation from a 25 year, 24 hour storm event, Om 10% of the total enclosed container volume of all containers, or 110% of the capacity of the largest container within its boundary, whichever is greater. • Secondary containment facilities shall be impervious to the materials stored therein for a minimum contact time of 72 hours. • Secondary containment facilities shall be maintained free of accumulated rainwater and spills. In the event of spills or leaks, accumulated rainwater and spills shall be collected and placed into drums. These liquids shall be handled as hazardous waste unless testing determines them to be non- hazardous. • Sufficient separation should be provided between stoned containers to allow for spill cleanup and emergency response access. • During the wet weather season (Oct 1 — April 30), each secondary containment facility shall be covered during non - working days, prior to and during rain events. • Keep material storage areas clean, organized and equipped with an ample supply of appropriate spill clean-up material (spill kit). • The spill kit should include, at a minimum: • I -Water Resistant Nylon Bag • 3 -0i1 Absorbent Socks 3 "x 4' • 2 -01 Absorbent Socks 3 "x 10' • 12 -0i1 Absorbent Pads 17"x19" • 1 -Pair Splash Resistant Goggles • 3 -Pair Nitrile Gloves • 10- Disposable Bags with Ties • Instructions 4-46 Volume 11 -- Construction Stonnwater Pollution Prevention February 2005 Table 4.4 Storm Drain Inlet Protetion Applicable for Type of Inlet Emergency Paved!

Conditions of Use Where storm drain inlets are to be made operational before permanent stabilization of the disturbed drainage area Protection should be provided for all storm drain inlets downslope and within 500 feet of a disturbed or construction area, unless the runoff that enters the catch basin will be conveyed to a sediment pond or trap. Inlet protection may be used anywhere to protect the drainage system. It is likely that the drainage system will still require cleaning. Table 4.9 lists several options for inlet protection. All of the methods for storm drain inlet protection are prone to plugging and require a high frequency of maintenance. Drainage areas should be limited to 1 acre or less. Emergency overflows may be required where stormwater ponding would cause a hazard. If an emergency overflow is provided, additional end -of -pipe treatment may be required. 442 Volume 11— Construction Sturmwater Pollution Prevenffon February 2005 Design and Excavated Drop Inlet Protection - An excavated impoundment around the Installation storm drain. Sediment settles out of the stormwater prior to entering the Specifications storm drain. • Depth 1 -2 ft as measured from the crest of the inlet structure. • Side Slopes of excavation no steeper than 2:1. • Minimum volume of excavation 35 cubic yards. • Shape basin to fit site with longest dimension oriented toward the longest inflow area. • Install provisions for draining to prevent standing water problems. • Clear the area of all debris. • Grade the approach to the inlet uniformly. • Drill weep holes into the side of the inlet. • Protect weep holes with screen wire and washed aggregate. • Seal weep holes when removing structure and stabilizing area. • It may be necessary to build a temporary dike to the down slope side of the structure to prevent bypass flow. Block and Gravel Filter - A barrier formed around the storm drain inlet with standard concrete blocks and gravel. See Figure 4.14. • Height 1 to 2 feet above inlet. • Recess the first row 2 inches into the ground for stability. • Support subsequent courses by placing a 2x4 through the block opening. • Do not use mortar. • Lay some blocks in the bottom row on their side for dewatering the pool. • Place hardware cloth or comparable wire mesh with 1/2-inch openings over all block openings. • Place gravel just below the top of blocks on slopes of 2:1 or flatter. • An alternative design is a gravel donut. • Inlet slope of 3:1. • Outlet slope of 2:1. • 1 -foot wide level stone area between the structure and the inlet. • Inlet slope stones 3 inches in diameter or larger. • Outlet slope use gravel'/- to 3 -inch at a minimum thickness of 1 -foot.

A temporary dike may be necessary on the dowelope side of the structure. Figure 4.14 - Block and Gravel Filter CQ Gravel Baetd7il Concrete Block Wire Screen or Filter Fabric Gravel and Wire Mesh Filter - A gravel barrier placed over the top of the inlet. This structure does not provide an overflow. • Hardware cloth or comparable wire mesh with #z -inch openings. • Coarse aggregate. • Height 1 -foot or more, 18 inches wider than inlet on all sides. • Place wire mesh over the drop inlet so that the wire extends a minimum of 1-foot beyond each side of the inlet structure. • If more than one strip of mesh is necessary, overlap the strips. • Place coarse aggregate over the wire mesh. • The depth of the gravel should be at least 12 inches over the entire inlet opening and extend at least 18 inches on all sides. 4-84 Volume 11- Construction Stormwater Pollution Prevention February 2005 February 2005 Catchbasin Filters - Inserts should be designed by the manufacturer for use at construction sites. The limited sediment storage capacity increases the amount of inspection and maintenance required, which may be daily for heavy sediment loads. The maintenance requirements can be reduced by combining a catchbasin filter with another type of inlet protection. This type of inlet protection provides flow bypass without overflow and therefore may be a better method for inlets located along active rights-of- way. • 5 cubic feet of storage. • Dewatering provisions. • High -flow bypass that will not clog under normal use at a construction site. • The catchbasin filter is inserted in the catchbasin just below the grating. Curb Inlet Protection with Wooden Weir — Barrier formed around a curb inlet with a wooden frame and gravel. • Wire mesh with 1/2-inch openings. • Extra strength filter cloth. • Construct a frame. • Attach the wire and filter fabric to the frame. • Pile coarse washed aggregate against wire/fabric. • Place weight on frame anchors. Block and Gravel Curb Inlet Protection — Barrier formed around an inlet with concrete blocks and gravel. See Figure 4.14. • Wire mesh with / -inch openings. • Place two concrete blocks on their sides abutting the curb at either side of the inlet opening. These are spacer blocks. • Place a 2x4 stud through the outer holes of each spacer block to align the front blocks. • Place blocks on their sides across the front of the inlet and abutting the spacer blocks. • Place wire mesh over the outside vertical face. • Pile coarse aggregate against the wire to the top of the barrier. Curb and Gutter Sediment Barrier — Sandbag or rock berm (riprap and aggregate) 3 feet high and 3 feet wide in a horseshoe shape. See Figure 4.16. • Construct a horseshoe shaped berm, faced with coarse aggregate if using riprap, 3 feet high and 3 feet wide, at least 2 feet from the inlet. • Construct a horseshoe shaped sedimentation trap on the outside of the berm sized to sediment trap standards for protecting a culvert inlet. Volume t! — Construction Stormwater Pollution Prevention 4-85 Maintenance • Catch basin filters should be inspected frequently, especially after Standards storm events. If the insert becomes clogged, it should be cleaned or replaced. • For systems using stone filters: If the stone filter becomes clogged with sediment, the stones must be pulled away from the inlet and cleaned or replaced. Since cleaning of gravel at a construction site may be difficult, an alternative approach would be to use the clogged stone as fill and put fresh stone around the inlet. • Do not wash sediment into storm drains while cleaning. Spread all excavated material evenly over the surrounding Land area or stockpile and stabilize as appropriate. 4-86 Volume 1! — Construction Stormwafer Pollution Prevention February 2005 BMP C233: Silt Fence Purpose Use of a silt fence reduces the transport of coarse sediment from a construction site by providing a temporary physical barrier to sediment and reducing the runoff velocities of overland flow. See Figure 4.19 for details on silt fence construction. Conditions of Use Silt fence may be used downslope of all disturbed areas. • Silt fence is not intended to treat concentrated flows, nor is it intended to treat substantial amounts of overland flow. Any concentrated flows must be conveyed through the drainage system to a sediment pond. The only circumstance in which overland flow can be treated solely by a silt fence, rather than by a sediment pond, is when the area draining to the fence is one acre or less and flow rates are less than 0.5 cfs. • Silt fences should not be constructed in streams or used in V- shaped ditches. They are not an adequate method of silt control for anything deeper than sheet or overland flow. Joints In triter fabric stall be spliced at posts.

Silt fence materials are available that have synthetic mesh backing attached. • Filter fabric material shall contain ultraviolet ray inhibitors and stabilizers to provide a minimum of six months of expected usable construction Life at a temperature range of 0 °F. to 120 °F. • 100 percent biodegradable silt fence is available that is strong, long lasting, and can be left in place after the project is completed, if permitted by local regulations. • Standard Notes for construction plans and specifications follow. Refer to Figure 4.19 for standard silt fence details. The contractor shall install and maintain temporary silt fences at the locations shown in the Plans. The silt fences shall be constructed in the areas of clearing, grading, or drainage prior to starting those activities. A silt fence shall not be considered temporary if the silt fence must function beyond the life of the contract. The silt fence shall prevent soil carried by runoff water from going beneath, through, or over the top of the silt fence, but shall allow the water to pass through the fence. The minimum height of the top of silt fence shall be 2 feet and the maximum height shall be 21 feet above the original ground surface. The geotextile shall be sewn together at the point of manufacture, or at an approved location as determined by the Engineer, to form geotextile lengths as required. All sewn seams shall be located at a support post Alternatively, two sections of silt fence can be overlapped, provided the Contractor can demonstrate, to the satisfaction of the Engineer, that the overlap is long enough and that the adjacent fence sections are close enough together to prevent silt laden water from escaping through the fence at the overlap. February 2005 Volume 11— Construction Stormwater Pollution Prevention 4-95 The geotextile shall be attached on the up -slope side of the posts and support system with staples, wire, or in accordance with the manufacturer's recommendations. The geotextile shall be attached to the posts in a manner that reduces the potential for geotextile tearing at the staples, wire, or other connection device. Silt fence back -up support for the geotextile in the form of a wire or plastic mesh is dependent on the properties of the geotextile selected for use. If wire or plastic back -up mesh is used, the mesh shall be fastened securely to the up -slope of the posts with the geotextile being up -slope of the mesh back -up support. The geotextile at the bottom of the fence shall be buried in a trench to a minimum depth of 4 inches below the ground surface. The trench shall be backfilled and the soil tamped in place over the buried portion of the geotextile, such that no flow can pass beneath the fence and scouring can not occur. When wire or polymeric back -up support mesh is used, the wire or polymeric mesh shall extend into the trench a minimum of 3 inches. The fence posts shall be placed or driven a minimum of 18 inches. A minimum depth of 12 inches is allowed if topsoil or other soft subgrade soil is not present and a minimum depth of 18 inches cannot be reached. Fence post depths shalt be increased by 6 inches if the fence is located on slopes of 3:1 or steeper and the slope is perpendicular to the fence. If required post depths cannot be obtained, the posts shall be adequately secured by bracing or guying to prevent overturning of the fence due to sediment loading. Silt fences shall be located on contour as much as possible, except at the ends of the fence, where the fence shall be turned uphill such that the silt fence captures the runoff water and prevents water from flowing around the end of the fence. If the fence must cross contours, with the exception of the ends of the fence, gravel check dams placed perpendicular to the back of the fence shall be used to minimize concentrated flow and erosion along the back of the fence. The gravel check dams shall be approximately 1- foot deep at the back of the fence. It shall be continued perpendicular to the fence at the same elevation until the top of the check dam intercepts the ground surface behind the fence. The gravel check dams shall consist of crushed surfacing base course, gravel backfill for walls, or shoulder ballast. The gravel check dams shall be located every 10 feet along the fence where the fence must cross contours. The slope of the fence line where contours must be crossed shall not be steeper than 3:1. Wood, steel or equivalent posts shall be used. Wood posts shall have minimum dimensions of 2 inches by 2 inches by 3 feet minimum length, and shall be free of defects such as knots, splits, or gouges. 4-96 Volume 11 — Construction StormwaterPollufion Prevention February 2005 February 2005 Steel posts shall consist of either size No 6 rebar or larger, ASTM A 120 steel pipe with a minimum diameter of I -inch, U, T, L, or C shape steel posts with a minimum weight of 135 lbs. /ft or other steel posts having equivalent strength and bending resistance to the post sizes listed. The spacing of the support posts shall be a maximum of 6 feet. Fence back -up support, if used, shall consist of steel wire with a maximum mesh spacing of 2 inches, or a prefabricated polymeric mesh. The strength of the wire or polymeric mesh shall be equivalent to or greater than 180 lbs. grab tensile strength. The polymeric mesh must be as resistant to ultraviolet radiation as the geotextile it supports. • Silt fence installation using the slicing method specification details follow. Refer to Figure 420 for slicing method details. The base of both end posts must be at least 2 to 4 inches above the top of the silt fence fabric on the middle posts for ditch checks to drain properly. Use a hand level or string level, if necessary, to mark base points before installation. Install posts 3 to 4 feet apart in critical retention areas and 6 to 7 feet apart in standard applications. Install posts 24 inches deep on the downstream side of the silt fence, and as dose as possible to the fabric, enabling posts to support the fabric from upstream water pressure. Install posts with the nipples facing away from the silt fence fabric. Attach the fabric to each post with three ties, all spaced within the top 8 inches of the fabric. Attach each tie diagonally 45 degrees through thefabric, with each puncture at least 1 inch vertically apart. In addition, each tie should be positioned to hang on a post nipple when tightening to prevent sagging. Wrap approximately 6 inches of fabric around the end posts and secure with 3 ties. No more than 24 inches of a 36 -inch fabric is allowed above ground level. The rope lock system must be used in all ditch check applications. The installation should be checked and corrected for any deviation before. compaction. Use a flat- bladed shovel to tuck fabric deeper into the ground if necessary. Compaction is vitally important for effective results. Compact the soil immediately next to the silt fence fabric with the front wheel of the tractor, skid steer, or roller exerting at least 60 pounds per square inch. Compact the upstream side first and then each side twice for a total of four trips. Volume 11— Construction Stonnwater Pollution Prevention 4 -97 Maintenance Standards • Any damage shall be repaired immediately. • If concentrated flows are evident uphill of the fence, they must be intercepted and conveyed to a sediment pond. • It is important to check the uphill side of the fence for signs of the fence clogging and acting as a barrier to flow and then causing channelization of flows parallel to the fence. If this occurs, replace the fence or remove the trapped sediment. • Sediment deposits shall either be removed when the deposit reaches approximately one -third the height of the silt fence, or a second silt fence shall be installed. • . If the filter fabric (geotextile) has deteriorated due to ultraviolet breakdown, it shall be replaced.
