Mullet, Mayor Department of Community Development Steve Lancaster, Director Mr. Jeff Davis Davis Properties P.O. Box 1043 Kent, WA 98035 -1043 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). Hope that helps.

The document mentions requesting EPA to separate out the eastern portion of the site, which will be developed with the warehouse /office building and associated parking, from the western portion of the site in terms of coverage by the Order. i • I'm wondering if EPA agreed to this request? Has the site been cleaned up to EPA's satisfaction? I don't see how our applicant can do excavation and construct a building on a site that still has contamination issues. Would appreciate any thoughts /info you have on this. Thanks much.

Then we can issue the shoreline permit and set a date for the shoreline variance hearing. Are there any dates that don't work for you /Ivana (whoever will be speaking for the project) in May or early June? Also, for the shoreline variance, I am assuming the height variance is not needed as the building is not higher than 35 feet. As a result, I am going to recommend in my staff report that the height variance not be approved, as it is not needed. Please let me know if this will be a problem, and then we will need to talk. Let me know about dates in May /June as soon as you can and about the height variance.

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. In 2002, SEPA was issued (E02 -021) to permit the construction of a subsurface barrier wall to encircle contaminated groundwater to control migration of contaminants into the Duwamish Waterway and Slip 6.

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 16th 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)). CL Page 2 of 7 04/14/2006 4:30:00 PM q: \Davis Properties \SEI'A Stall Rpt.doc Planned Action SEPA Re. — E05 -011 Davis Development — Former Rhone/Poulenc Site April 14, 2006 Summary of Primary Impacts: Earth The site is generally flat and almost entirely covered by impervious surface except for some landscaping around existing buildings (to be demolished) and adjacent to the chain link fence that surrounds the property. 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. CL Page 3 of 7 04/18/2006 8:58:00 AM q: \Davis Properties\SEPA Staff Rpt.doc Planned Action SEPA Rev.— E05 -011 Davis Development — Former Rhone /Poulenc Site April 14, 2006 Treated storm water runoff will discharge directly to the Duwamish River; water quality treatment will be provided for the development using the requirements of the King County Surface Water Design Manual. 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— Former Rhone /Poulenc Site April 14, 2006 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. Energy/Natural Resources 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.

The other parcel will be developed with an 84,000 sq. ft. warehouse /office building with associated parking. Housing Not applicable. 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.

This portion of the code requires that a professional archaeologist be on site when excavations into historically native soil take place in an area of archaeological potential to ensure that all State statues regarding archaeological conservation /preservation are implemented. This will be a requirement of the shoreline substantial development permit for the site. The applicant is also 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 also be a requirement of the shoreline permit and the building permits issued for both the western and eastern portion of the parcel. Transportation The site is accessed via East Marginal Way South. An easement was granted to the Oregon - Washington Railroad and Navigation Company, the Great Northern Railway Company, Northern Pacific Railway Company and Chicago, Milwaukee, St. Paul and Pacific Railroad Company for railroad tracks on the eastern portion of the site adjoining East Marginal Way. One curb cut currently exists on the site; a second curb cut is proposed to provide additional access to the proposed development on the site. Port of Seattle Slip No. 6 borders the property on the south. Three METRO bus routes serve the site on East Marginal Way South. A Traffic Impact Analysis was submitted by the applicant and reviewed by the City's traffic engineer. The TIA estimates that no more than 81 PM peak hour trips would be generated by the proposed development. Traffic impact fees, based on the 2006 Traffic Impact Fee Schedule, will be levied as part of the building permit. Public Services The new development will be served by Tukwila police and fire service. Utilities Utilities currently available at the site include electric, natural gas, water, refuse service, telephone, storm water and sanitary sewer. Adequate utilities are available to serve the new warehouse /office building.

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 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.geomatrix.com RECEIVED 'APR 0 7 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 StormceptorlD, 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.

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 — I 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 permit stage: 1. During a site inspection on January 27, 2006, it was noted that western boundary of the site does not extend to the berm, leaving sediment to enter the river.

Jurisdiction and Approval Authority. The Western 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 soils, 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 wail. 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:.fromvother regulatory jurisdictions such as the State, 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 dearly 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 northwestern corner of the Facility. Comments regarding the January 20 soil removal plan wig 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. MAR 27 2006 11:18AM HP SERJET 3200 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 eastern boundary of the western parcel. This page states that access to the western parcel is to be through the Tenant's adjoining facility to the north. The treatment building, extraction wells, associated piping, and at least some of the monitoring wells will be located inside.this fenced area on the western par el. • Drawing 3 of Appendix C, however, appears to indicate that gates will be located in: the new • • boundary fencing between the eastern and western parcels. This drawingdoes 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 weds will be located between these fences, although no gates are Indicated. The drawing also seems to indicate a double fence located at thatop 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 inck de construction • of a permanent fence 'along the western parcel boundaries," implying that all of the fencing will be replaced. The Redevelopment Work Plan must be revised to indude.a figure-dearly 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 Pla•does not state whether the western parcel will':beopen 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 western . parcel during business hours. For example, how will the treatment building 'and wet heads be secured? Where will warning signs be installed end what will they state? How will piping and ancillary equipment be protected? Page 2 of the Redevelopment Work Plan indicates that "security will be provided by lAAi" after installation of the new security fencing. • Changes to the security fencing 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.Orderand 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 latercorrective measures Implementation orother work that may required unde•the Order. The Redevelopment Work Plan must be revised to specify how ready access to wells, treatment equipment, and/orthe barrier wall cap will be • assured if, 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. P.5 MAR 27 2006 11:19AM HP SERJET 3200 P • 6 S. • 5. Protection, and Maintenance of Interim Measures. The Redevelopment Work Plan must • be revised to spocify.what Measuret• will be taken to ensure that the existing interim. • measures facilities are adequately protected from the Tehanrs activitiet 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 barriem. Are there restrictions . on the Tenant's activities within a specified distance of the' building which houses th e treatment plant? Is digging 'or other. reconstruction•prohibited? Is the Tenant required to • • immediately notify Respondents of any damage to or problemsobserVed With the interim . measure (e.g., leaks, cracking pavement, etc.)? . . . 6. • Capping.

Corrective Measures Study and selection by EPA of a final correctivemeasure. The process of selecting a corrective measure Is. subject to public review and comment Tribal • consultations, and consultations with other federal agencies under Endangered Species Act. For example, dIscuisloristegarding the original placement of thibarrier • wall included 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 western 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.

Number 12, °Access," requires that after reasonable advance written notice from Landlord, except in case of emergency, Tenant shall permit Landlord or the agencies, Including EPA, to enter the Premises at all reasonable times for purposes of repair, environmental remediat on, 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 dosed 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.

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.

Jill Mosqueda, P.E. The City Of Tukwila Public Works Department (PW) has the following comments regarding your application for the above permits. 1. PW development assumes the existing signalized access has approval from BNSF. However, the Applicant has not provided approval for the new access to the south. The Applicant must provide approval from BNSF to cross its land for the new access. 2. Cyndy Knighton is reviewing the Traffic Impact Analysis. Transpo Group worked with Cyndy on the scope of analysis. Based on existing adequate capacity and existing infrastructure, Cyndy expects the analysis will be accepted as submitted. Except for access approval, PW Development does not expect significant transportation/traffic changes that would affect approvals for the permits listed above. PW Development is awaiting a written approval from Cyndy. 3. Ryan Larson is reviewing the Technical Information Report. Based on what the Applicant provided, PW Development does not expect significant storm drainage changes that would affect approvals for the permits listed above. PW Development is awaiting written preliminary approval from Ryan Larson. 4. Traffic impact fees, based on the 2006 Traffic Impact Fee Schedule, will be levied as part of the building permit.

CC: Ryan Larson MEMORANDUM January 27, 2006 TO: Carol FROM: Sandra RE: Davis Property and Investment (Rhone - Polenc site), Review of Response to City's Comments I have reviewed the letter, plans and reports submitted to Tukwila in response to our comments from September and October 2005. Here are my observations: 1. The letter from Barghausen states that the groundwater treatment system has already been relocated into a new pre -fab building. However, the demolition plan still calls out relocation of the treatment system and the plans do not show the new building. The plans should be updated to reflect these changes. Also, Barghausen's letter states that the lift station is no longer needed to discharge treated groundwater to the County's sewer system, but the Geomatrix report states that the lift station will continue to operate as before. Which is correct? 2. The Western Parcel Redevelopment Work Plan, prepared by Geomatrix, discusses the new permanent stormwater treatment system and says that stormwater will be directed through a Vortechs water quality system that will be located in the southwest corner of the site outside the groundwater barrier wall. A drawing showing the location of the treatment system was not provided, as the City did not receive the corresponding appendix to the work plan. However, this proposed treatment system is not consistent with what Barghausen shows on its stormwater plans or mentions in the Shoreline Project Narrative. Sheet C -1 shows a water quality/wet pond. Or perhaps these are two separate treatment systems. Sheet C -4 and item C of the Shoreline Permit Project Narrative show Stormceptors as the water quality control features. It seems that there is a lack of communication between the project engineer and Geomatrix. Whichever system of combination of systems is finally utilized it must be made clear on one set of plans and must guarantee that it will meet Ecology water quality standards. 3. The letter from Barghausen states that a work plan for addressing contamination in the eastern part of the site has been submitted to EPA and that a copy was provided to the City. A copy was not provided. 4. The City requested a copy of the EPA — approved operation, monitoring, inspection and maintenance plan for operation of the barrier wall, extraction wells and groundwater treatment system. Although the letter from Barghausen states that a copy was included in the submittal, it was not included. 5. I reviewed the Western Parcel Redevelopment Work Plan prepared by Geomatrix and feel that it adequately addresses closure of wells no longer in use; protection of and future access to the wells to be retained; health and safety issues during construction; and waste management issues. However, I do have a few comments: a. Details on the wheel wash and its proposed location should be provided; • • b. The approximate location of the personal decontamination station should be shown on the plans. c. What is the contingency plan for relocating the wells after paving (in order to extend the casings and install new surface monuments) if using the metal detector does not work? 6. During a site walk on January 27th, it was noted that the filter fence along the western boundary of the site on the north does not extend to the berm, thus leaving a gap which could allow sediment to enter the river. This should be corrected before site grading activities are undertaken.

Your applications for Administrative Design Review (L05 -055) Shoreline (L05 -050), Shoreline Variance (L05 -051) and SEPA (E05 -011) located at 9229East Marginal Way South have been found to be complete on January 12, 2006 for the purposes of meeting state mandated time requirements. The next step is for you to install the public notice board on the site within 14 days of the date of this letter. You received information on how to prepare and install the sign with your application packet. If you need another set of those instructions, you may obtain them at the Department of Cotnmunity Development (DCD). Please call me 3 days prior to installing the notice board to so I can arrange for the mailing associated with the Notice of Application. I will post the site with the Notice of Application. For the Notice of Application mailing, I will need 6 additional copies of the revised plan sets, SEPA checklist and Planned Action Checklist.

Enclosed are the following documents for your review and approval: 1. Six (6) copies of the revised plan set 2. Six (6) copies of the Traffic Impact Analysis prepared by the Transpo Group, dated December 2005 3. Six (6) copies of the Western Parcel Redevelopment Work Plan prepared by Geomatrix Consultants, Inc., dated November 2005 4. Six (6) copies of the revised Shoreline Permit narrative 5. Six (6) copies of the BNSF deed and easement document recording no. 4781818 6. Six (6) copies of the Groundwater Pretreatment System Relocation Plan prepared by Geomatrix Consultants, Inc., dated January 2005 7. 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.barghausen.com Carol Lumb, Senior Planner City of Tukwila Department of Community Development -2- January 4, 2006 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. 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. 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. 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. 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 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. 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 proposall 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 I 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 I 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 • • 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 on 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. 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.

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.

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.

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.

Projects /PRE04 -040 Rhone - Poulenc land use Corn 1 1 MEMORANDUM September 22, 2005 TO: Carol FROM: Sandra RE: Revised Review Comments Davis Property and Investment SEPA Checklist/Shoreline Variance This memo is a revision to my original comments on the SEPA Checklist, Shoreline Variance and the site plans and includes a summary of information I obtained from EPA regarding the site remediation. 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 last year, 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 • • 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. Plans: 2. The plans should show the three groundwater recovery wells in addition to the monitoring wells. 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, 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. 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. • • i�_� Geomatrix September 16, 2005 8769.005 Ms. Carol Lumb Senior Planner City of Tukwila Department of Community Development 6300 Southcenter Boulevard, #100 Tukwila, Washington 98188 Subject: Exemption from a Substantial Development Permit Former Rhone- Poulenc Facility 9229 East Marginal Way Tukwila, Washington Dear Ms. Lumb: RECEIVED • COMMUNITY DEVELOPMENT Container Properties, L.L.C. (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). This activity: • Is being conducted as an investigation prior to the planned redevelopment of the site; • A SEPA checklist and application for this redevelopment have already be submitted to the City of Tukwila for review; One Union Square, 600 University Street, Suite 1020 Seattle, Washington 98101 -4107 Tel 206.342.1760 Fax 206.342.1 761 www.geomatrix.com • • Ms. Carol Lumb City of Tukwila September 16, 2005 Page 2 • Will not interfere with the normal public use of the surface waters; • Will have no significant adverse impact on the environment; and • Does not involve installation of a structure, and upon completion the excavations will be backfilled and compacted prior to redevelopment of the site.

Carol »> "Jeff Davis" <jeffd(davispropertieslic.com> 09/02/05 04:22PM »> Carol, [truncated by sender] MEMORANDUM September 8, 2005 TO: Carol FROM: Sandra RE: Davis Property and Investment, Preliminary Review Comments Following are my preliminary comments on the SEPA Checklist and the site plans. 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. • Carol Lumb City of Tukwila Department of Community Development 6300 Southcenter Boulevard Tukwila, WA 98188 CIVIL ENGINEERING, LAND PLANNING, SURVEYING, ENVIRONMENTAL SERVICES September 7, 2005 HAND DELIVERY RE: Davis Property and Investment 9229 East Marginal Way South, Tukwila City of Tukwila File Nos.

SUMMARY OF PROPOSED AC The project is to construct a subsurface barrier wall encircling contaminated groundwater to control migration of contaminants into the Duwamish River and Slip 6. The wall will be approximately 2300 linear feet long and 50 to 70 feet deep. The Environmental Protection Agency (EPA) Region 10 is the lead governmental agency for the site. The site facility is regulated under Resource Conservation and Recovery Act (RCRA). The scope of this project at this time is for implementation of interim measures, which include a low permeable barrier wall with groundwater recovery for hydraulic control of the impacted groundwater. II. GENERAL INFORMATION Project Name: Implementation of interim measures for environmental cleanup at the former Rhone Poulenc site. Applicant: RCI Environmental Inc. Location: 9229 East Marginal Way South Zoning and Comprehensive Plan Designation: MIC/H III. REVIEW PROCESS This proposal was identified as a potential Planned Action as it met the requirements listed under Tukwila Municipal Code (TMC) Section 21.04.152. As part of this Planned Action review process, the proposed project is analyzed to ensure that all impacts have been mitigated as part of 1998 EIS and also if the proposal is consistent with the Tukwila Comprehensive Plan. Tukwila's Manufacturing and Industrial Center (MIC) is an important regional center of industrial activity. Industrial . development over the most of the sub -area was evaluated in multi -site environmental review. In 1992, a programmatic environmental impact statement (EIS) was prepared for the Duwamish Corridor master plan, a proposal to redevelop Boeing properties in the MIC over a 10 year period. In 1998, sub -area plan/EIS updates extended the previous analysis of the corridor's Boeing properties (about 650 acres) to the entire MIC sub -area (about 1,370 acres). As part of this Planned Action review for the current proposal, the impacts of the current proposal are compared to 1998 Integrated GMA Implementation Plan and Final Environmental Impact Statement in order to ensure that all impacts have been mitigated. 1 IV. BACKGROUND /PROPOSAL The project site is 21.5 acres, 19.5 of which is on -shore and 2 acres of which are offshore intertidal areas in the Duwamish Waterway. The subject site is within 200 feet shoreline of the Duwamish River and is zoned Manufacturing Industrial Center/Heavy (MIC/H). The property is partially paved with a few buildings and surrounded by fencing and secured gates. The property is flat except near the intertidal areas adjacent to Slip 6 and the Duwamish Waterway. The site is a former industrial facility purchased by Container Properties L.L.C. from Rhone Poulenc. The facility produced vanillin and was closed in 1991. Past process activities at the site introduced contaminants to the soils and groundwater. Primary contaminants included toluene and dissolved metals (primarily copper, arsenic and chromium). There are currently no manufacturing activities at the site. A small vapor extraction and emission control system is presently active at the site. At the time the facility was closed, process equipment, most of the tanks and several buildings were dismantled or removed. Northwest Container Services is currently leasing the facility and using it as shipping center for its ocean-going containers. The site facility is regulated under Resource Conservation and Recovery Act (RCRA). This project is a RCRA corrective action under Administrative Order of Consent No. 1091- 11- 20- 3008(h) between Container Properties, L.L.C., Rhodia Inc., and the USEPA Region 10, dated March 1993, as amended in February 1999. The order of consent lists different components of the clean up process that include interim measures (short term actions to control ongoing risks while a final remedy is being selected); RCRA facility investigation to assess the nature and extent of contamination identified during facility assessment; corrective measures study to identify and evaluate different alternative measures to remediate the site; and corrective measures implementation that includes detailed design, construction, operation, maintenance and monitoring of the chosen remedy. At this time the scope of the project is limited to implementation of interim measures, which include a low permeable barrier wall with groundwater recovery for hydraulic control of the impacted groundwater. The barrier wall is proposed to enclose, to the maximum extent practicable, source areas and affected groundwater. An Impermix barrier wall constructed using vibrated beam technology, will be installed along the western and southern portions of the wall, which border the Duwamish Waterway and Slip 6. A soil - bentonite barrier wall will be constructed using slurry wall technology along the northern and western segments, which comprise the inland portions of the barrier. Also, a groundwater recovery system will be installed within the containment area to maintain an inward hydraulic gradient and a water level monitoring system will be installed to measure the groundwater level inside the contained area and between the barrier wall and the Duwamish Waterway. The recovered groundwater will be discharged to the King County Department of Natural Resources sewer for final treatment and discharge. 2 V.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. Section E requires a complete description of the objectives and alternatives of your proposal and should not be summarized here. A Hydraulic Control Interim Measures (HCIM) is proposed for the site. This HCIM is being done with the concurrence of EPA Region 10. The objective of the HCIM is to control migration of site contaminants into the Duwamish River and Slip 6. The HCIM is a combination of a low permeable barrier wall with groundwater recovery for hydraulic control of the impacted groundwater. The total site is approximately 21.5 (19.5 onshore, 2.0 intertidal) acres. The proposed slurry wall is located in the westerly half of the area of the former Rhone - Poulenc industrial facility. The barrier wall will be approximately 2300 linear feet long and 50 to 70 feet deep. The west and south portions of the barrier wall will be constructed using "Impermix" a self- hardening cement bentonite slurry wall. The north and east portions of the barrier will be constructed using soil bentonite slurry wall. The barrier wall will enclose an area of approximately 6.9 acres. A groundwater extraction system will be located inside the perimeter of the barrier wall to maintain a 1-foot hydraulic head difference between the inside and outside of the barrier wall. The barrier wall alignment will be pretenched with conventional heavy construction equipment to a depth of approximately 20 feet. This will be done to allow the cutting and capping of existing facility piping and to allow the slurry wall installation and contractor uninterrupted access to the aquitard. Following installation of the slurry wall, storm water drainage will be reconnected to existing piping for discharge to the existing outfall. 7. Location of the proposal.

The subsurface barrier wall is keyed a minimum of 2 feet into an continuous aquitard located at a depth of between 50 and 75 feet below ground surface. The barrier wall was constructed using vibrated beam technology with Impermix® backfill. The interim measures are intended to control the discharge of affected groundwater from the RPI site. An inward hydraulic gradient is maintained by recovery of groundwater from extraction wells located inside the barrier wall. The barrier wall provides a flow barrier that reduces the quantity of groundwater that must be extracted to maintain an inward hydraulic gradient. A groundwater pretreatment system receives extracted groundwater and treats it to meet water quality requirements required for discharge to the Metro -King County wastewater collection and treatment system. Monitoring wells are included in the interim measure to provide information concerning hydraulic gradients and groundwater quality. The groundwater recovery system consists of three 6- inch - diameter extraction wells (EX -1, EX -2, and EX -3, as shown on Figure 2), completed with 20 -foot long stainless steel wire -wrap screens. The wells are located in the north central portion of the area enclosed by the barrier wall. The wells are equipped with Grundfos electric submersible pumps, capable of operating at flow rates up to about 20 gallons per minute (gpm). Groundwater extracted from the recovery wells is piped to a pretreatment system located inside a dedicated pretreatment building (Figure 2). The pretreatment system consists of: • A purge /sump tank; • Bag filters to remove fines; • Two granular activated carbon (GAC) units, operated in series, to remove organic contaminants; • Associated instruments and controls. The groundwater recovery and pretreatment system is equipped with a programmable logic controller (PLC) which monitors groundwater levels in designated control wells, controls the extraction well pumps, and monitors instrumentation for alarm conditions. The pretreatment 1:\8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 2 zati Geomatrix system Process and Instrumentation Diagram is shown on Figure 3. Pretreated groundwater is discharged to the King County -Metro wastewater collection and treatment system under Permit No. 7789 -01. The maximum average discharge allowed under this permit is 65,000 gallons per day (daily average flow rate of 45 gpm). The performance monitoring system for the Interim Measure consists of 36 performance monitoring wells (Figure 2). All 36 wells are monitored for water levels; 17 are also monitored for chemical constituents, including 16 groundwater monitoring wells and extraction well EX -3. Two of these wells (DM -8 and MW -49) are equipped with pressure transducers for measuring water levels. Water level data from these two wells are monitored by the PLC to track the groundwater elevation difference inside and outside the barrier wall. Water levels from the two transducers are recorded every 15 minutes by the data recorder and the PLC , so that there is redundancy in data storage. The data recorder is used as the primary source for downloading data. The average water level elevation difference between the two control wells is calculated from the recorded data and used to control the operation of the groundwater extraction well pumps to ensure a net inward 1 -foot hydraulic gradient (based on averaged levels) is maintained across the barrier wall. Details of these systems and calculations are described in the following sections. 2.0 GROUNDWATER RECOVERY SYSTEM OPERATIONS, MAINTENANCE, AND INSPECTION Recovery system equipment that will require long -term operation and maintenance includes the groundwater recovery wells and pumps, tanks, piping, filters, GAC units, water level monitoring wells and sensors, meters, and the automatic control system. Each of these items requires periodic inspection and maintenance to reliably meet interim measure objectives. All personnel performing operations; maintenance, and/or inspections for the facility must comply with the Health and Safety Plan (Appendix A). A signed copy of the Health and Safety Plan will be kept at the site with this Revised OMIMP. The Health and Safety Plan may be updated at any time at the discretion of Container Properties. Whenever the Health and Safety Plan is updated, it will be placed at the site with this Revised OMIMP. Operations procedures for the groundwater recovery and pretreatment system have been prepared and attached to this OMIMP as Appendix B for reference purposes only. These procedures are intended to serve as a guide for operation of the system. The, procedures may be revised at the discretion of Container Properties to ensure that appropriate, safe, clear, and complete procedures are available for system operators. A current and complete set of J: \8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 3 Geomatrix operations procedures will be maintained within the pretreatment building at the site for use in operating the system. Modification, revision, deletion, and/or replacement of the operations procedures included in Appendix B of this document will not be considered a modification of the Order. The following is a list of procedures included in Appendix B: Description Appendix Page 1.0 Safety Considerations 2 2.0 Routine Start-up 3 3.0 Downloading Data 8 4.0 Routine Shut -down 10 5.0 Startup After Power Failure 11 6.0 Data Recorder and PLC Time/Date Set or Change 14 7.0 Transducer Maintenance 15 8.0 Carbon Adsorber Maintenance 16 9.0 Bag Filter Maintenance 18 10.0 Purge Tank Operation 19 11.0 Containment Area Pump -out 21 12.0 Transducer Calibration Check 22 13.0 Auto - dialer Shortcuts 24 14.0 Connecting to the PLC via the site laptop 26 2.1 GROUNDWATER RECOVERY WELLS AND PIPING Pumping wells can become fouled for a variety of reasons, including accumulation of silt within the sand pack, chemical precipitation, and biological growth. Chemical fouling, corrosion, or biofouling can also reduce the capacity of the pumping wells. Operation of the recovery wells will be monitored to identify problems due to fouling. The groundwater flow rate produced from individual wells will be routinely observed during system operations. If the well flow shows a sudden decrease, the potential aboveground causes, including power supply, meters, controls, piping, and filter plugging will be assessed. If this evaluation does not identify the source of the problem, the submersible pump may be pulled and checked in accordance with the manufacturer's recommendations. The submersible pump will be repaired or replaced if required. If the pump and above - ground causes do not JA8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 4 zak Geomatrix appear to be the source of production loss, the well will be inspected and, if necessary, redeveloped or chemically treated (e.g., acid treatment for chemical fouling or shock chlorination for biofouling). If these actions do not restore the well to an acceptable capacity, an engineering study to correct the problem will be initiated or, alternatively, the well will be replaced. The recovery well pumps can be operated manually or they can be automatically actuated by the PLC. The PLC allows remote monitoring of the pump status. Equipment failures or problems associated with the operation of the groundwater recovery or pretreatment system will be corrected in a timely manner. Under normal conditions, the well pumps are under automatic control. Cycling of the groundwater recovery well pumps is controlled by the PLC based on the average water elevation differences calculated for Wells DM -8 and MW -49. The water levels measured in the two control wells every 15 minutes are averaged to ensure comparability between the tidally influenced outside well (DM -8) and the dampened inside well (MW -49). A 72 -hour moving average water level is calculated for each of the wells. The averaging procedure and water level comparisons are performed by the PLC in the following manner: • The 72 -hour average is calculated for both Wells DM -8 (outside barrier wall) and MW -49 (inside barrier wall) from recorded water level readings simultaneously taken from the transducers every 15 minutes... • The 72 -hour water level averages are updated every 8 hours. In updating the 72 -hour average, the water level data from the earliest 8 -hour period included in the average is replaced with the latest 8 hours of water levels. This recalculation provides a new "moving" 72 -hour average water level for both wells. • The two 72 -hour averages are compared to one another to calculate the difference in water levels (OWL). • Based on the difference in water levels between the two control wells, the pumps will be controlled as described in the following Table 1. J:\8769.000 RCI R- P\077\Revised OMIMP- ver- 02.doc 5 Geomatrix TABLE 1 GROUNDWATER EXTRACTION WELL CONTROL STRATEGY Former Rhone- Poulenc Site Tukwila, Washington Well Status Lead Lag -1 Lag -2 Alarm OFF SP, SP3 SP5 ON SP2 SP4 SP6 SP7 Notes: SP; = Set points for groundwater level controller to activate extraction wells. The above pump control strategy has been programmed into the PLC and is currently being implemented. Set points to implement this strategy can be manually input to the PLC via the PLC interface "Level" screen to direct pump control. (See Appendix B Operation Procedure 2.0 for an example of the "Level" screen settings.) The PLC compares the difference in 72- hour average water levels in Wells DM -8 and MW -49 to the set points to implement the above pump control actions. The last set point, SP7, issues an alarm indicating that all three wells are pumping and may not be controlling the groundwater level. This alarm point is set at a differential of 1.2 feet to provide a safety factor of 0.2 feet over the performance standard. The PLC rotates lead and lag well status among the three wells, with the status changing every eight hours, to ensure routine use of all three wells. Control programming allows individual on and off points for each well (i.e., for SP1 through SP6); these individual set points are set to implement pump control as needed to attain the inward gradient performance standard. These set points are normal operating parameters that may be changed as needed by Container Properties as part of normal operations. However, the setpoint for the compliance alarm (SP7) will not be changed without prior notice to EPA. Changes to these set points or strategy will be noted in the log book. To date the 8 -hour recalculation period has been sufficient to effectively control water levels while dampening out the effects of transient water level changes. The averaging and recalculation periods may be adjusted by Container Properties, based on operational experience. Any changes to the operation or changes in the recalculation period will be evaluated and reported in the monthly progress reports required by the Order. Operation and calibration of the transducers will be checked quarterly by comparing direct manual measurements of water levels in Wells DM -8 and MW -49 collected during quarterly J:'8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 6 • Geomatrix performance monitoring with water levels indicated by the data recorder and PLC. Given the accuracy of the transducers (± 0.05% of the 30 psi full scale reading) and the approximate manual water level measurement accuracy (± 0.06 ft), the two readings should agree within 0.19 ft. If the difference between manual and transducer - measured water levels is greater than 0.2 ft., the transducer will be recalibrated or replaced. Calibration checks will be recorded on the calibration check form included in Appendix B. If recalibration of the transducers is necessary, the calibration will be performed and recorded in accordance with the Transducer Calibration Procedure also included in Appendix B. 2.2 GROUNDWATER PRETREATMENT SYSTEM The groundwater pretreatment system includes a purge /sump tank, purge /sump feed pump, bag filter, and GAC units, as shown on Figures 3 and 4. The purge /sump tank and feed pump are used to feed purge water from well sampling to the groundwater pretreatment system for pretreatment and discharge to the King County -Metro publicly -owned treatment works (POTW). The pretreatment system requires periodic inspection, monitoring, and maintenance for effective operation. Operations issues include potential plugging of the filters or GAC units, consumption of carbon by groundwater constituents, fouling of piping and pumps, and failure of system instruments. The groundwater treatment system will be•checked and inspected onsite weekly or as needed to maintain the system. System operations will be monitored remotely as needed to ensure proper operation. Samples will be collected as appropriate to confirm proper operation and as needed to comply with the discharge permit. Maintenance will be performed as appropriate, based on'preventative maintenance requirements for system equipment and the results of monitoring and inspection. The major pieces of equipment included in the system, the expected useful life, and supplier information are summarized in Appendix C. A set of operation manuals for the major pieces of equipment and controls are kept at the pretreatment building. 2.2.1 Groundwater Recovery Pretreatment System Operations, Monitoring and Inspection Operation of the pretreatment system is continuously monitored and controlled by the PLC. The autodialer will provide notice to off -site personnel in the event an alarm condition occurs. A physical inspection of the treatment system will be performed weekly or as needed to maintain the system. Details of treatment system monitoring and inspection are described below. Procedures for operation of the groundwater recovery and pretreatment system are included in Appendix B: J: \8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 7 alc= Geomatrix Plugging or clogging in the GAC units or bag filters will be detected by the pressure differential switches which are monitored by the PLC. The switches will sense the pressure differential across each of the GAC units and the bag filter. At a preset level, the PLC will issue an alarm to the autodialer indicating a high pressure differential. The pressure differential readings will be checked against pressure gauge readings monthly. General inspection and maintenance of the groundwater pretreatment system will be performed during the site visits. Piping, fittings, and valves will be inspected for leaks, cracks, damage, and obstructions. Centrifugal pumps will be checked for proper flow and maintained in accordance with manufacturer's instructions. Treatment equipment will be inspected for leakage, defects, signs of wear, damage, or over - pressure. Each inspection will be logged in the treatment plant log. Maintenance needs will be recorded in the log. The final action taken for maintenance will also be noted in the log. Data will be downloaded from the PLC data recorder at least monthly. These data will be reviewed and evaluated at least monthly. The review will include calculation of moving 72 -hour average water levels for the approved water level control wells, MW -49 and DM -8. The downloaded data will be reviewed at an off -site location and the data files will be maintained at an off -site location. Data from the redundant storage on the PLC will be downloaded at least twice yearly and stored at an off -site location. 2.2.2 Purge /Sump Tank Operation The purge /sump tank is used to manage groundwater from purging monitoring wells during sampling events, manage excess water from collecting samples to monitor the pretreatment system and to manage any water collected within the secondary containment system surrounding the pretreatment equipment. This tank will be operated in general accordance with the procedures outlined in Operations Procedure 10.0 (Appendix B). The tank is equipped with a lid that is maintained in -place at all times that water is not being added to the tank. Water is placed into the purge tank manually. This water is then manually pumped into the pretreatment system, as shown in Figure 3, for treatment prior to discharge under the King County -Metro discharge permit. Water from the surge /sump tank is treated by filtration and carbon adsorption prior to discharge along with treated groundwater from the extraction wells. Water is present in the tank for only a short time during filling and draining operations; the tank is not used for storage. A small amount of water may remain in the tank after pumping due to a lip that is present on the outlet fitting. Water will be drained from the tank so that no more than 1 inch of water remains in the bottom. J:16769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 8 Geomatrix Groundwater produced from purging the monitoring wells, as well as groundwater recovered from the extraction wells, may be classified as a listed dangerous waste (0220) under the State of Washington's Dangerous Waste Regulations (Washington State RCRA program). As described in the Dangerous Waste Regulations under WAC 173 - 303 -071 (3), groundwater from both sources is excluded from most of the dangerous waste management requirements specified under WAC 173 -303. Additionally, the discharge of monitoring well purge water is not prohibited under 40 CFR 403.5, as the purge water constituents are not expected to pass through the POTW, cause interference with the POTW, create fire or explosion hazards for the POTW, cause corrosive damage to the POTW, obstruct flow to or in the POTW, cause interference with the POTW, generate heat that may inhibit biological activity in the POTW, or release toxic gases, vapors, or fumes in the sewer or POTW. The pretreatment system is designed to treat potential groundwater constituents and comply with discharge standards established by King County -Metro. The dangerous waste classification and groundwater composition has been provided to King County -Metro as part of the permitting process. The discharge of the treated groundwater to a POTW under the terms of the King County -Metro permit addresses the requirements for exclusion under WAC 173- 303 -071 (3). Therefore, the discharge of treated groundwater that was recovered using the extraction wells, recovered to purge monitoring wells, or excess water produced during sampling of the pretreatment system meets the requirements specified in the Washington Dangerous Waste regulations. 2.2.3 Treated Groundwater Discharge Groundwater treated by the system is discharged to the King County -Metro sewer system for final treatment at a POTW. In the original system design, treated groundwater was discharged to the on -site lift station. The lift station pumps then transferred the groundwater to the King County -Metro sewer via an underground line. In the revised design, the lift station has been eliminated from the system to improve overall reliability (See Figure 2). Pretreated groundwater is now discharged directly to the underground line that discharges to the King County -Metro sewer. 2.2.4 Groundwater Pretreatment System Water Quality Sampling The pretreatment system includes sample taps before and after each treatment unit and in the locked sump located outside the pretreatment building (For King County -Metro access), as shown on Figure 3. Samples will be collected once monthly to evaluate treatment system performance, determine if the lead GAC unit requires replacement, and assess water quality relative to King County -Metro discharge criteria. While the normal sampling locations are J:\8769.000 RCI R- P\077\Revised OMIMP- ver- 02.doc • Geomatrix inside the pretreatment building, sampling of the treated effluent can be performed at the piping inlet sump by unlocking the sump lid to access the sample port. Sampling to evaluate system performance. Analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX) will be used to assess loading on the GAC units, and to determine whether it is necessary to replace the lead GAC canister. BTEX will be analyzed on the influent and effluent from each of two GAC units to assess loading. The GAC canister will be replaced if it becomes saturated with toluene, as determined by comparing influent and effluent concentrations for the lead GAC unit. Sampling for King County -Metro permit requirements. The King County -Metro discharge permit requires sampling of treated effluent water quality to assess compliance with discharge criteria. Samples must be analyzed for non -polar fat, oil, and grease (FOG), pH, and BTEX. The overall sampling and analysis program for the groundwater pretreatment system, including sampling for system performance and for the discharge permit, is summarized in Table 2. TABLE 2 GROUNDWATER PRETREATMENT SYSTEM MONITORING Former Rhone- Poulenc Site Tukwila, Washington Sampling. Frequency Analytical Parameters Sample Point Monthly FOG, BTEX, pH Filter Influent Monthly FOG, BTEX Lead GAC Canister (C -1) Effluent Monthly FOG, BTEX, pH Lag GAC Canister (C -2) Effluent Quarterly BTEX, pH, total metals Recovery well EX -3 Samples are collected from the pretreatment system sample ports as follows: • Purge a minimum of 500 milliliters (mL) from the sample tap into a container. • Gently fill the sample container directly from the sample tap, extending the sample tap tubing to the bottom of the container. • Analyze samples as indicated in Table 1. Samples for BTEX must be collected in a volatile organic analysis (VOA) vial and filled without any headspace. • Place the purge water into the purge /sump tank and pump the water through the pretreatment system. J: \6769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 10 Geomatrix Samples collected for monitoring the groundwater treatment system performance will be labeled and handled in accordance with the quality control procedures specified in the Interim Measures Performance Monitoring Plan Quality Assurance Project Plan presented in the IMCWP: Samples collected for compliance with the discharge permit will be handled and analyzed in accordance with requirements specified in the discharge permit. 2.2.5 Potential Operations Problems The groundwater extraction and pretreatment system has been designed to provide reliable and consistent operation and treatment. Although the system is simple, several mechanical and electrical components can fail and create problems for operation. The system includes a PLC and autodialer that have been designed to identify and manage likely failures until an operator can respond to the problem and implement corrective action. The likely operating problems and anticipated remedies are described in this subsection. The expected life for the process components is also presented in this subsection. The likely operating problems and anticipated remedies are tabulated below: Potential Operations Problem Anticipated Remedy 1. Plugging of filters (high pressure drop) Change filter bags. 2. Saturation of carbon Replace spent carbon in lead unit with fresh carbon. 3. Plugging of carbon bed (high pressure drop) Open carbon unit and clean/flush carbon surface. 4. Power failure Notify system engineer or project manager, then contact Seattle City Light to restore power. 5. Transducer measurement error. Recalibrate or replace transducer. 6. Pump failure Replace or repair failed pump. 7. Flow meter failure Replace or repair failed flow meter. Use redundant metering capability for monitoring during repair /replacement. 8. PLC failure Replace /repair PLC. Operate manually during repair or replacement. Attach transducers to temporary data logger. 9. Data recorder failure Replace /repair data recorder. Use PLC flashcard for data downloading. 10. Valve failure Replace defective valve. 11. Piping break Identify location of break; repair piping. The most likely operations problems are Problems 1 and 2 noted above, which are expected to occur routinely and can be readily addressed without adversely affecting system operation. Filter plugging can be sensed by process instrumentation and can be changed easily and with minimal effect on operation. To address Problem 2, saturated activated carbon, the entire system must be temporarily shut down to change carbon. It is anticipated that such shutdowns J:\8769.000 RCI R- P\077'Revised OMIMP- ver- 02.doc 11 MW -49, monitor and control pumping cycles, monitor system operating conditions such as pressure differentials across the GAC units, initiate system shutdown under specific conditions, provide redundant data storage, and to issue alarms. Through the normal course of operations, the PLC may require reprogramming to optimize system performance. The PLC records water levels in the transducers in Wells DM -8 and MW -49 every 15 minutes and updates the 72 -hour ' average water levels every 8 hours. Based on these average water levels, the PLC activates or deactivates the extraction well pumps. The PLC also monitors pretreatment system instruments ' and issues shutdowns and alarms as appropriate. The PLC displays this information on an interface screen mounted on the front panel, next to the data recorder. The PLC user interface screen has multiple pages that display the following information: ' flow (gpm), total flow (gallons), extraction well pump status, pumping well rotation, alarm status, flow alarm settings, level control setpoints and alarms, transducer calibration settings, J: \8769.000 RC! R- P \077\Revised OMIMP- ver- 02.doc 12 . Geomatrix groundwater levels for Wells DM -8 and MW -49 (current, most recent complete 8 -hour average, and 72 -hour average), and the most recent calculated inward hydraulic gradient based on the 72 -hour averages. Details for each display page are described in the Operation Procedures (Appendix B, Section 2.0). The PLC user interface, in combination with the modem, PLC, and certain adapters, allows remote monitoring and control of the system. Using the site laptop (with proprietary Siemens software), an operator can remotely view the user interface screen displays in real time. The software also allows remote input of the same parameters (e.g., level control setpoints) that are possible while onsite. Details regarding local and remote monitoring and input are described in the operations procedures included in Appendix B. A digital data recorder is used to record groundwater levels in Wells DM -8 and MW -49, the total system flow rate from Meter FM -4, and the difference in the 72 -hour average water levels calculated by the PLC. These data are also recorded by the Compact Flash card installed on the PLC interface screen, providing a back -up for data. The recorder receives water level and flow rate readings relayed from the PLC and records the readings to diskette every 15 minutes. The data recorder displays the current water level and flow readings. The floppy disk is removed from the recorder at least monthly and the recorded data are exported to an Excel spreadsheet using the proprietary Honeywell software, Trend Manager Pro (Version 3.8). The exported data are then used to assess attainment of the hydraulic gradient performance standard specified in the IMCWP and to report flow data to King County -Metro. A single floppy diskette has the capacity to store all recorded data for a period of 4 to 5 months of continuous operation. At the discretion of Container Properties, the Compact Flash card rather than the data recorder diskette may be used as the primary source of data for off -site data evaluation. If the Compact Flash card is used for download data to assess attainment of the hydraulic gradient performance standard, the Honeywell software will not be used. Data can be downloaded from the Compact Flash card directly into Excel. If Container Properties elects to change the primary source of water level data to the Compact Flash card, notification will be provided to EPA in the monthly reports prepared in accordance with the Order. An autodialer is used by the automatic control system to provide alarm notifications to off -site operators. The autodialer receives alarm signals generated by the PLC and dials the designated operations staff to provide notice. The following alarms are issued by the autodialer to the system operator and presented in Table 3: J: \8769.000 RC1 R- P\077\Revised OMIMP- ver- 02.doc 13 Performance monitoring of the HCIM will be conducted in accordance with the Interim Measures PMP, as revised on December 16, 2005. The revised PMP describes the monitoring ]:\8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 14 zak Geomatrix approach for attaining the objectives specified in the Approval with Modifications. Performance monitoring activities currently include: • Measurement of water levels every month by collecting manual measurements at 36 groundwater monitoring wells and the three extraction wells onsite. These water levels will be reported as part of the quarterly groundwater monitoring program. • Collection of quarterly water quality samples from 17 (including well EX -3) exterior and interior groundwater monitoring wells, and one of the extraction wells. The groundwater quality samples are analyzed for BTEX, dissolved and total metals, major cations and anions, total phosphorus, and ammonia- nitrogen. • Water levels will also be recorded approximately every 15 minutes in the two control wells, DM -8 and MW -49, using data from water level transducers installed in these wells. The water level data from these two wells is used to control the operation of the groundwater pre - treatment system. An inward hydraulic gradient is maintained into the containment area by groundwater . withdrawal from within the barrier wall. The performance standard for maintaining the inward gradient is to keep the mean level of the groundwater within the containment area at a level 1 -foot below the mean groundwater level as measured in DM -8 (outside the barrier wall) and MW -49 (inside the barrier wall). Additional details regarding performance monitoring program for the RPI site are presented in the revised PMP which is included as Appendix D. 4.0 INTERIM MEASURES INSPECTION AND MAINTENANCE PLAN The interim . measures for the RPI site require periodic inspection and maintenance to ensure that interim action objectives are attained. Inspection and maintenance for the groundwater treatment system were discussed in Section 2. The plan for inspecting and maintaining site interim measures are described below. Site pavement should be maintained to minimize infiltration of precipitation. The barrier wall must be inspected and maintained to address failures identified by the performance monitoring system, settlement failures, and potential failures that may occur due to disaster events (such as an earthquake or flood). Any failures of the site pavement or barrier wall (including the groundwater recovery and pretreatment system) will be repaired or addressed in a timely manner. 4.1 PAVEMENT INSPECTION AND MAINTENANCE Maintenance of the existing pavement is necessary to minimize infiltration of precipitation and to prevent potential human or ecological exposure to site soils. The existing paved areas will be inspected annually and maintained as deemed necessary by Container Properties. If pavement conditions deteriorate such that storm water is infiltrating and causing significant J: \8769.000 RCI R- P \077\Revised OMIMP- ver- 02.doc 15 zef& Geomatrix water level rise within the barrier wall, the pavement may be repaired or covered, at the discretion of Container Properties. ' 4.2 BARRIER WALL INSPECTION AND MAINTENANCE Inspection of the barrier wall will consist of annual site walks around the entire alignment to ' observe the surface condition of the barrier wall protective cover. The protective cover will be checked for ruts, cracking, ponding, erosion or other signs of failure. Additional inspections will be performed within 30 days of a seismic event, if significant seismic activity ' (an earthquake of magnitude 5.8 or greater) occurs in the Puget Sound area. Observations and measurements will be recorded in an Inspection Log Book and reported as described in Damage to the wall could be repaired by such methods as vibrated beam/Impermix® wall construction, jet grouting, sheet pile installation, or deep soil mixing. The actual method of wall repair will depend on the nature and extent of the suspected wall failure. In addition, since the purpose of the barrier wall is to reduce the rate of leakage into the contained area, the wall ' may be deemed acceptable by Container Properties if acceptable pumping rates can maintain the hydraulic gradient performance standard. 5.0 RECORDKEEPING AND REPORTING ' Operation and inspection of the interim measure requires appropriate recordkeeping and reporting. Routine reporting of normal monitoring maintenance is necessary to document attainment of the performance standard specified in the approved IMCWP. Timely reports are ' also necessary in the event that releases or non - routine conditions occur.

Groundwater recovered from the site as part of the interim measure may be classified as a dangerous waste due to the potential to contain toluene (U220). Since it is not known if toluene is detectable in the groundwater at any given time, it should be assumed that spilled groundwater is a dangerous waste. The reportable quantity for a toluene spill is 1,000 lb. Since toluene is only a trace constituent in site groundwater, it is highly unlikely that a reportable quantity of toluene would be released to surface water; a release of approximately 350,000 gallons of water containing the highest historical toluene concentration of 340 mg/L would have to be released to reach the reportable quantity for toluene. At the maximum expected pumping rate (45 gpm), it would take more than five days to pump this volume of groundwater. It is expected that a release of this magnitude would be identified and controlled in a short time. Therefore, it is not expected that it will be necessary to make reports to the National Response Center. Spills and releases outside of secondary containment areas will be reported to the following contacts: Contact Name Title Phone Number Jeff Davis Property Manager, DPI 253- 872 -9522 Gary Dupuy Site Coordinator, Geomatrix 206 - 342 -1777 Larry McGaughey Engineer, Geomatrix 206 - 342 -1788 WA Dept. of Emergency Management Spill response center 800- 258 -5990 King County Investigator, King County 206 - 263 -3000 Christy Brown Project Manager, EPA 206 -553 -8506 Upon identifying a spill, the operator shall notify Gary Dupuy or Larry McGaughey of Geomatrix and provide details regarding the time, description, location, and volume of the spill. The Site Manager or the Engineer will then contact the other parties identified in the above spill reporting list. Verbal reporting to the Washington State Department of Ecology (Ecology) should be completed within about one hour of learning of the spill. In addition to the above J:\8769.000 RCI R- P\077\Revised OMIMP- ver- 02.doc 18 dam Geomatrix list, if an emergency occurs as a result of a spill that represents an immediate safety, fire, or explosion hazard, emergency response agencies will be contacted by calling 911. In the event of a spill, appropriate containment and cleanup will be implemented to mitigate any environmental effects resulting from the release. The above list may be updated as appropriate; a current list will be maintained at the site in the current version of the OMIMP. A written report documenting the cause, nature and extent of the spill, cleanup /containment action taken, and any corrective action taken will be prepared and submitted to Ecology, EPA and King County within 30 days of the event. The OMIMP maintained at the pretreatment facility will be updated as needed to ensure that the above reporting list is kept current. 5.2.2 Emergency Conditions Emergency conditions other than spills may also occur for the interim measures. Emergency conditions include, but are limited to, automatic shutdown of the system, catastrophic damage due to earthquakes or storms, long -term power failure, long -term loss of data recording capability, process failure, or equipment failure causing extended shutdown. Other situations that are judged to constitute an emergency condition by site management will also be reported as described below. Operations staff must report all non - normal operations to the Engineer. The Engineer will assess the situation, consult with the Site Manager, and implement emergency reporting as appropriate. If an emergency condition exists, any or all of the following personnel may be contacted by phone within 24 hours of identifying the emergency condition: Contact Name Title Phone Number Larry McGaughey Engineer, Geomatrix 206- 342 -1788 Gary Dupuy Site Coordinator, Geomatrix 206 - 342 -1777 Arnaud Girard Investigator, King County 206- 263 -3012 Christy Brown Project Manager, EPA 206 -553 -8506 Mr. Arnaud Girard of King County will be contacted regarding any emergency condition that may affect the nature or quality of the pretreated effluent discharged to the sanitary sewer.

J:\2769.000 RCI R- PW77\Appendix B \Operating Procedures- ver- 06.doc 2 2.0 ROUTINE START -UP Start -up When starting up the system, pay close attention to the operating conditions to ensure all Information components are operating properly. Procedure Step Start -Up 1 The PLC and data recorder should always be on unless there is a power outage or the circuit breaker has been tripped. If the system is off, check the appropriate circuit breakers, and then verify the building has power. Notify system engineer or project manager if PLC or data recorder remain off. Check data recorder screen to confirm that water levels from Wells DM -8 and MW-49, the difference in the 72 -hour average water levels in MW-49 and DM -8, and the effluent flow rate are being displayed. Check the PLC user interface screens against the photograph examples below (see Screens 1 to 5 below). 2 Make sure the appropriate valves are open and closed based upon the Piping and Instrumentation Diagram (Figure 3). Normal operations require flow through the inlet flow meters, one filter unit, the two series -flow carbon adsorbers, the effluent flow meter, and the discharge piping. 3 Turn the three well pump control switches, located to the left of the PLC control panel, to the AUTO setting. The system is now in routine operations mode and will be under automatic control. 4 Check the difference in water levels displayed by the data recorder with the recorded set point against the control chart (see Screen 3 below "Level Control Screen ") to determine whether none, one, two, or three pumps should be running and compare to actual well operation status. 5 As appropriate based reaches the appropriate described in the table _ on the pump operation status, verify that the flow rates at influent and effluent flow below. flow rate meters, as Extraction Well Expected Flow Rate (gpm) EX -1 10 - 14 EX -2 6 -9 EX -3 14 —19 6 As appropriate based on the pump operation status, verify that operating pressures throughout the system are appropriate. High differential pressures ( >10 psi) across any one piece of equipment (filters, GAC units) should be investigated immediately as it indicates clogging. 7 Inspect the above grade lines and the pretreatment system for evidence of leaks. Turn the well pumps off and implement . appropriate maintenance for any leaks discovered.

EPA informed Container Properties that in accordance with Paragraph 7.1 of the Administrative Order on Consent for Corrective Action (Order), it intended to conditionally approve the. IM Work Plan with modifications. The conditional approval was issued by EPA in May 2002. The key components of the hydraulic control measures included installation of a low - permeability subsurface barrier wall surrounding the contaminated area and installation of a groundwater recovery system to maintain an inward hydraulic gradient. The conditional approval required that an approved performance monitoring plan (PMP) be implemented with the approved interim measure. The performance monitoring program requirements specified in the conditional approval included: • Immediate detection of a failure or release from the barrier wall. • Verification of whether the interim measure is performing as required. • Monitoring the rate of migration of contaminants remaining in the river bank and critical habitat outside the barrier wall. A PMP was issued by Geomatrix on June 3, 2003, incorporating preceding meeting discussions and EPA comments. The June 2003 PMP was employed by Geomatrix Consultants, Inc: ( Geomatrix) through November 15, 2005. In September 2005, Geomatrix submitted an Addendum to Interim Measures Performance Monitoring Plan to EPA, proposing to eliminate monthly general parameter measurements and the monthly reporting of water levels. EPA approved the Addendum in a letter to Geomatrix received on November 17, 2005. In the letter, EPA mandates that a revised Interim Measures Performance Monitoring Plan incorporating these approved revisions be submitted within thirty (30) calendar days of receipt of their letter. This document presents the revised PMP for the 1:\8769.000 RCI R -P\066 \Revised Fornier RP PMP.doc 1 Revised 12/16/05 Zak- Geomatrix barrier wall interim measure. Details concerning the goals and objectives of the monitoring plan are described in Section 2.0. 2.0 MONITORING PLAN OBJECTIVE The objective of this monitoring plan is to respond to the three requirements identified by EPA as stated previously. Additionally, the objective is to present,a robust monitoring plan foi both pre- and post - construction monitoring, also as noted in EPA's May 2, 2002, Conditional Approval letter. Section 3.0 describes the monitoring well network at the Site, and Section 4.0 presents the performance monitoring plan that will be implemented starting in November 2005. Section 5.0 discusses the general approach to well abandonment that will be implemented. The performance monitoring quality assurance /quality control plan is referenced in Section 6.0. Section 7.0 summarizes the reports that will be submitted as part of performance monitoring. 3.0 MONITORING WELL INSTALLATION Figure 1 shows the location of the wells (MW -47 through MW -59) that were installed after barrier wall construction at the Site, as well as the rest of the groundwater monitoring wells. The wells were installed as a series of well pairs inside and outside of the barrier wall at approximately 300 to 400 foot spacing. Pre - existing wells were adopted or used as either interior or exterior wells, depending on the exact location of the barrier. Each well pair consists of a shallower well screened between 10 and 25 feet below ground surface (bgs) (approximate screen elevation of 6 to -9 feet mean sea level [nisi]) to evaluate groundwater conditions in the upper portion of the aquifer, and a deeper well screened between 35 to 45 feet bgs (approximate screen elevation -19 to -29 feet msl) to evaluate groundwater conditions in the lower portion of the aquifer.. Only shallower wells were placed along the northern and eastern sides of the barrier since no significant contaminants have been. identified in these areas. Twenty -five wells were installed (or adopted where possible) as wells to specifically monitor the performance of the wall. These wells are referred to as the barrier well network. The well locations were selected based on reviewing the concentration patterns of dissolved metals (principally copper, arsenic, and mercury) and the distribution of elevated pH readings as noted in the direct -push investigations performed at the Site. The spacing between the well pairs meets the recommendations of the EPA guidance document regarding sub - surface engineered. J:\8769.000 RCI R -P \066 \Revised Former RP PMP.doc Revised 12/16/05 2 ro Geomatrix barriers (EPA, August 1998). This document recommends a minimum spacing between wells of 400. feet, with wells located within. 30 . feet of the barrier. wall. The well depth intervals are based on the monitoring intervals in previous wells used.onsite, with .wells in the Upper Aquifer divided into a shallow zone (called the Upper zone) and deeper. zone (the Intermediate/Lower zone). The Upper zone has 'slightly higher permeability sediments than those present in the deeper. Intermediate/Lower zone. _;These two depth intervals were selected to ensure consistency with historic groundwater monitoring practices at the Site. Monitoring water levels at the two depth intervals allows for rapid identification of potential • leakage through the barrier wall and provides some indication of vertical groundwater flow through the aquitard layer. The exterior network wells next to the west and south barrier wall alignment were installed in September 2002, before the wall was constructed. All wells that were installed or adopted into the program have subgrade completions and are clearly marked. Figure 1 shows which network wells were constructed prior to installation of the wall. The remaining network wells were completed during or immediately after the wall was constructed. Lithologic logs and construction logs for the newer wells are presented in Appendix A. 4.0 PERFORMANCE MONITORING This section describes the proposed performance monitoring program that will be implemented from November 2005 onwards. Performance monitoring will focus on determining whether the interim action system is meeting the performance goals and objectives specified in EPA's May 2, 2002 conditional approval. Section 4.1 describes how water level measurements will be recorded and evaluated to determine if the interim action system is providing adequate hydraulic containment. Section 4.2 describes the groundwater quality monitoring that will be used to determine if the wall has controlled the release of constituents of concern (COCs), or if mobilization of COCs outside and in the vicinity of the wall has occurred. 4.1 PERFORMANCE MONITORING — WATER LEVEL MEASUREMENT Water level monitoring is the primary determinant of whether the wall is meeting the performance goals. The following discussion clarifies how measurement of water levels determines how the wall is performing. The barrier walls and the aquitard will behave ideally if they minimize the response within the wall to tidal fluctuations. Ideal behavior can also be demonstrated if pumping within the wall .1:\8769.000 RCI R -P\066 \Revised Former RP PMP.doc 3_ Revised 12/16/05 Geomatrix.. causes no noticeable change in 'water level outside the barrier wall. If the barrier wall is performing to specifications and if the aquitard is relatively homogenous, the ideal behavior of water levels inside the wall in response to pumping will be relatively uniform and flat across the site .away from the immediate vicinity of the extraction well(s): This is because the wall . will ideally limit horizontal inflow of groundwater in response to the imposed inward hydraulic gradient. If the wall leaks, then the uniform pattern will be altered, and the wells near the leak along the interior of the wall should show higher groundwater elevations than those away from the leak. Such mounding could occur in either of the aquifer zones since the wall has the potential for leakage along its entire length and depth. This mounding would impart a detectable slope to the water table as water leaks through the wall. However, even if the barrier wall is performing ideally, the underlying aquitard may leak and the tidal signal could be transmitted inside the wall. If the aquitard has a preferential vertical flow path, then apparent groundwater mounding will occur in the deeper (Intermediate/Lower) zone wells across the site, since the water will be flowing vertically upwards from aquitard in response to pumping. During pump operation, water levels will need to be collected from the barrier well network and across the site using existing monitoring wells to diagnose these differing types of behaviors. Currently, relatively little overall change in water levels is occurring because groundwater flow conditions within the wall have reached steady state. Even if the walls or aquitard leak, steady state control of water levels as needed to attain the appropriate inward gradient can be achieved by pumping larger quantities of groundwater. The magnitude and impact of the leakage will be determined before any decisions are made concerning the need for mitigation efforts. An inward hydraulic gradient will continue to be maintained into the containment area by groundwater withdrawal from within the barrier wall. The performance standard for maintaining the inward gradient is to keep the mean level of the groundwater within the Containment area at a level 1 -foot below the mean groundwater level as measured in selected control wells outside the barrier (MW -49 and DM -8). This approach is considered equivalent in protectiveness to maintaining a 1 -foot difference in water level relative to the Duwamish Waterway, as proposed by EPA. This approach simplifies water level monitoring, improves overall effectiveness of the monitoring system, is used to automatically control pumping, and improves safety when compared to direct monitoring at the river level. Differences in water levels between the Upper and Intermediate/Lower zone wells in each well pair will be compared as described in Section 4.1 to monitor for leakage through the wall or vertical groundwater flow through the aquitard. An Operations Monitoring and Inspection 1:\8769.000 RCI R -P\066 \Revised Former RP PMP.doc 4 Revised 12/16/05 Geomatrix Maintenance Plan (OMIMP) for the Site was written by Geomatrix and submitted to EPA with: the. Proposed, Modification in. June 2005 (Geomatrix, 2005a). The OMIMP :provides: additional details about the operation of the groundwater pre- treatment system operation including the use of the control wells. The barrier wall groundwater water level measurements will be collected to confirm that hydraulic gradient performance criteria are Met. The pumping system is operates using . pressure transducers placed within a single well inside the wall and a similarly constructed well located outside the barrier wall (wells MW -49 and DM -8). The pump controller is set to automatically maintain the desired difference between the mean groundwater levels in the selected wells. An appropriate statistical procedure is used by the automatic control system to determine the mean groundwater level both inside and outside the barrier wall for the same time period. The continuous water level monitoring approach is currently easily implemented and maintained, allowing real -time acquisition and continuous measurements. Measuring water levels in the aquifer outside the wall takes advantage of the dampening effect in the aquifer, and the absence of wakes makes interpretation of results more reliable. Ready access provided by installation in a well simplifies maintenance and improve reliability. Monthly manual monitoring of water levels in 36 wells both inside and outside the barrier wall will continue to be conducted in addition to •continuous monitoring of DM -8 and MW -49 for control purposes (Table 1). Figure 2 shows the location of the wells that will be manually monitored for water levels. Monthly water level monitoring of the wells shown in Figure 2 will be adequate to confirm performance of the barrier wall and groundwater recovery system and to detect failure with sufficient frequency to provide . for mitigation, if appropriate. These water levels will be measured during either a low tide or high tide to minimize the influence of tidal changes during the measurement period. The observed responses in water levels will be compared to similar tidal cycles observed during the month -long water level monitoring event. On November 15, 2005, EPA approved the elimination of the monthly reporting of water levels. Monthly water level measurements will continue to be collected and reported as part of the quarterly monitoring reports. J:\8769.000 RCI R- P\066\Revised Fomur RP PMP.doc Revised 12/16/05 5 ,L Geomatrix 4.2 PERFORMANCE MONITORING.— WATER QUALITY MONITORING Water quality monitoring during the performance monitoring period will consist of measuring general parameters and specific chemical analyses to determine if the wall has minimized the . potential for release of COCs through the wall or identify mobilization of COCs outside and in the vicinity of the wall. Section 4:2.1 describes ,the general parameter monitoring. program, land Section 4.2.2 describes the chemical analyses that will be used to monitor the wall performance. Table 1 lists the details of the proposed water quality monitoring program: 4.2.1 General Parameters The conditional approval includes requirements for monitoring water quality as part of performance monitoring. The objective of water quality monitoring is to assess changes in groundwater chemistry outside the wall and to determine if COCs are passing through the barrier wall. General water quality parameters have reached steady state conditions as of September 2005. EPA approved a request to eliminate monthly groundwater monitoring for the general water quality parameters (pH, oxidation/reduction potential [ORP], dissolved oxygen, specific conductance, and temperature) in a letter dated November 15, 2005, and subsequently received on November 17, 2005. These parameters will remain as part of the quarterly monitoring. These general parameters are indicative of changes in geochemistry. Specifically, a significant change in pH or ORP could indicate the potential for affecting either metals migration or metals adsorption. Groundwater flow through the wall is very slow, so the quarterly general parameter monitoring will be more than sufficient to monitor geochemical changes in the aquifer. Figure 2 shows the location of wells that will be monitored quarterly for general parameters. General parameter sampling will be performed on the barrier network exterior wells (those wells located to the west and south of the barrier wall) simultaneously with quarterly groundwater chemical sampling. This will provide water quality data for deep and shallow groundwater and will occur with a frequency sufficient to allow timely mitigation, if warranted. Diurnal tidal fluctuations and the presence of a low permeability barrier will limit the rate of geochemical change in the aquifer west and south of the wall. This anticipated rate of change should be slow enough so that quarterly monitoring is sufficient to allow for timely mitigation of off -site changes in water chemistry, if required. 4.2.2 Chemical Analyses Figure 2 shows the location of wells that will be included in the chemical monitoring program. Chemical monitoring will be conducted quarterly. The annual performance evaluation report 1:18769.000 RCI R -P\066 \Revised Fourier RP PMP.doc Revised 12/16/05 will evaluate the need for either more frequent monitoring or reduction in monitoring frequency. The analytes that will continue to be monitored outside the wall will include the following: Geomatrix BTEX will be analyzed as the representative volatile organic compounds (VOCs) in the groundwater samples. Samples will be analyzed for total and dissolved metals, including alurmnum, arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium, thallium, vanadium, and zinc. • Groundwater samples will be collected from these same wells for analysis of general water chemistry parameters, including major cations (iron, manganese, calcium, sodium, potassium, and magnesium), major anions (bicarbonate /carbonate, chloride, sulfate, nitrate /nitrate, and dissolved silica), total phosphorus, and ammonia - nitrogen. The ion balance will be calculated and trends in overall water chemistry will be reported using Piper or other appropriate diagrams. • . All exterior monitoring network wells along the west and south portions of the wall will be sampled during the failing tide. Ebb tide responses will be determined based on data obtained during the month -long water level sampling conducted after completion of the wall. • All monitoring and recovery wells will be sampled in accordance with the approved Interim Measures Quality Assurance Project Plan. • During purging, general parameters (temperature, pH, specific conductance, dissolved oxygen, ORP, and turbidity) will be monitored for stabilization in all of the wells prior to sampling. Reduction in the number of analytes in the future should be considered if justified by the analytical results. 4.3 PERFORMANCE MONITORING SCHEDULE Performance monitoring will include monthly water level measurements and quarterly chemical sampling. Monthly water levels and quarterly water quality data will be reported quarterly. 5.0 WELL ABANDONMENT Since the wall is complete, many existing monitoring wells inside the barrier wall can be abandoned, since there is little justification for maintaining such a large network of wells, the wells could interfere with site operations, and they could lead to additional contamination.

From November 2005 onwards, reporting will consist of: • Quarterly groundwater monitoring reports will be prepared after each sampling event to analyze and present the monitoring results. The quarterly reports will include the following: O Data tables and trend charts. O Monthly water level measurements. o Groundwater elevation contour maps and isoconcentration maps. o Stiff diagrams plotted with a consistent scale with three wells plotted per page and a summary plot showing Stiff diagrams for all results. o Piper diagrams summarizing water chemistry and prepared as appropriate to • present the data in relevant groupings, such as internal wells, extemal wells, shallow wells or deep wells. All wells will be plotted on a single Piper diagram. o Brief discussion of the specific trends in the data and other items of interest. o Laboratory reports and relevant monthly reports, included as appendixes. o Calculations and supporting spreadsheets, appended to the quarterly reports.

Abbot Filter Bags Construction --Sewn -seam bags are the most common, and easy to handle. Heat - welded seam bags have no needle holes or loose threads that could' contribute to fluid contamination. Micron ratings—Absolute-rated Met bags will retain at least 9096 of particles of the specified micron size. All other bags will retain particles, but not .to any percent efficiency. Often referred to as nominal rated To acheive the desired filtration, select a bag • with a micron size smaller than the panicles you want to fitter Bags with a glazed finish have minimal fiber migration (con- tamination from fiber filter media, such as felt). Filler bags are not reusable. unless noted. To order a filter bag for your hous- ing, use.the following tables as a guide. • • "Filter bags serve as futering media in filter bag housings. They may also be used in adapter head or slip -on applications that do not use housings. Filter bags are efficient economical, and easy to change, while offering high flow rates with low pressure drops. They provide good dirt- holcing capacities, trapping dirt within the bag. _ • Types ofBags =We offer bags that fit into standard housings, slip -on bags that do not require a housing but rather a clamp or wire, and grab =on bags that do notregtare a housing but rather a threaded adapter head Trade Size For Housing Lg Dia 1 r to 81/2- 16" to 17" 2 8' to 81/2' 32' 3 41h" to 5' B" to B1/4" 4 442' to 5' 14" 8 6" to 61/2' 20' to 22" 9 6" to 61/2' 31' to 33' 12 8'12- to 9' 34" Felt Filter.

Explosion- proof, heavy duty, industrial unit has patented and unique new design which provides sensitivity to differential pressures as low as 10 inches of water (254 mm w.c.), yet handles total pressure of 1500 psi (108 bar). Unit yields deadbands apprordmateiy 5% of range, with zero setpoint shift due to variation in working pressures. Friction is minimized and repeatability increased by allowing range spring to act directly on diaphragm plate. Rolling diaphragm design maintains constant effective area to further reduce friction. Diaphragm is allowed to °seat°, allowing application of full rated pressure, up to 1500 psi (108 bar), on either high or low pressure port, without damage. Special over - .travel feature prevents overtightening of range adjust screw. Choose optional brass chamber for water and water -based fluids or 316 stain- less steel for harsher applications.

LOCATION: Select a location where the temperature lirnit of 220 °F (104 °C) will not be exceeded. Locate the switch as dose as possible to the pressure source for best response Longer lengths • of tubing will not affect the accuracy of the actuation point but can . . increase response time slightly. • . . 2. MOUNTING: Avoid mounting surfaces. with excess vibration which could cause false actuation when pressure is near set - point. •Attadi switch with two 3/16 - screws or bolts (not included) through. mounting bracket. Normal position is with housing vertical. 3. PRESSURE CONNECTION: Connect source(s) of pressure, vacuum or differential pressure to the 1 /8- NPT,portsas follows:: A. Differential Pressures - Connect higher pressure -to High Pressure port (bottom) and lower pressure to Low Pressure port (side) . B. Pressure Onty — Connect a single positive pressure to High • Pressure port on. bottom .and leave Low Pressure port on side. vented to atmosphere. • C. Vacuum Only - Connect a single negative (vacuum) pressure to Low Pressure port on side and leave High Pressure port on bottom vented to atmosphere 4. ELECTRICAL CONNECTIONS: Either one or two SPDT snap switches are. provided with normally open contacts closing and . normally closed contacts opening when pressure or vacuum increases beyond the set -point A Wire h accordance with .local electrical codes. B. Wire lead models - Thread wires through conduit and connect to leads from snap switch(es). Black= Common, Red = Normally Closed, Blue= Normally Open C Terminal block models - Loosen screws on terminal block(s), insert stripped and tinned wires in side openings and tighten screws.

To change the set - point, connect tubing or piping from high • pressure port on bottom to one leg of a tee. Connect the second leg to a pressure gage of known accuracy and in an appropriate range. The third leg should be connected to a controllable pressure source. 2. Connect a volt/ohm meter or other circuit tester to snap switch to indicate when switching occurs 3. Slowly apply pressure to the system and note the pressure at which switching occurs, ff adjustment is necessary, turn the adjustment screw (located internally at center next to snap switch) clockwise to raise or counterclockwise to Tower the actuation point. When the required setting has been reached, exercise the switch through two or three additional cycles to verify consistent operation . MAINTENANCE The moving parts of these switches need no maintenance or lubrication. The set -point is the only user adjustment. On models with optional drain fitting, periodically rotate small captive screw from side to side several times to keep drain path clear. Units in need of repair should be returned to the factory prepaid. CAUTION: Make sure conduit or cable are properly sealed Electrical components must be kept free of moisture, including condensation, at all times To prevent ignition of hazardous atmosphere, disconnect the device from the supply circuit before opening Keep assembly tightly closed . when in operation Undone MhRanb: Teo SOW meant, at Dwym °C°tpnrfd6 one common!

Will the room heat up faster if I put the thermostat on 90 degrees when 1 get hone? A. No, the thermostat is just an on -off switch that is temperature sensitive. The heater is either on or off. Q. My baseboards are on outside walls, should fan heaters be also? A. No, a fan - heater, recessed into an outside wall, will create extra heat -loss. and air leakage for that room. An inside wall, facing a cold window, is the best location. Q. My thermostat is above my fan - heater, Why? A. The fan heater blows warm air away from itself and into the room. By the time the warm air has recirculated and reached the thermostat above the heater, a comfortable room temperature has been achieved. Q. Will my electric bill be lower if 1 use 120 volt heaters ?" A. No, 120 volt and 240-volt heaters, of the same size, will use the same amount of power, measured in watts or kilowatts. Your electric company • charges by kilowatt hours. Q. S hould 1 clean my heater? A. Yes, once a year, you must clean and inspect your heaters. See the section "Taking Care of Your Heating System" on the previous page. You may request a copy of the operation & maintenance for your heater if you have lost it. Q. Why does my new heater produce smoke when I turn it on? A. In the manufacturing process, a light lubricant is used, which will burn when the heater is energized. The smoke will stop after the heater has fully heated. It is recommended to open a window during initial operation, but this is no cause for alarm. Q. If 1 need to replace my heater, can 1 use a higher wattage heater? A. Your electrical system was sized for the original heater's wattage. A smaller heater would be OK, but a larger heater may create a hazard. Q. Are King Heaters actually trade in Seattle, Washington. A. Yes, Since 1958 we have made quality heating products for residential, commercial and industrial needs in the same location - Seattle, Washington. King Electrical Mfg.

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:\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 1 LA 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 3: \8769.000 RC1 R- P \060\RP -Site Develop WP- ver- 03.doc 2 Geomatrix provisions to ensure that the HCIM facilities and monitoring wells can be freely accessed after control of western parcel is assumed by IAAI.

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 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. J:\8769.000 RCI R- P\06O\RP -Site Develop WP- ver- 03.doc 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 1:\8769.000 RCI R-P\060\RP-Site Develop WP- ver- 03.doc 5 • i= 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 • • Geomatrix 3.0 SITE REDEVELOPMENT PLAN 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. Wells 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:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 7 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, C1, DM -1A, DM -1B, DM -6, and E3). The rationale for abandonment of these wells is as follows: • 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. J:\8769.000 RC] R- P\060\RP -Site Develop WP- ver -03.doc 8 Geomatrix 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 1: \8769.000 RCl R- P \060\RP -Site Develop WP- ver- 03.doc 9 • • Geomatrix • Remove catch basins leading to the sewer lines. The storm sewers will be left in place after disconnecting them from the discharge line. 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 be 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 1: \8769.000 RC! R- P\060\RP -Site Develop WP- ver- 03.doc 10 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. ]:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 11 • 4.0 CONSTRUCTION PLAN Geomatrix 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 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:\8769.000 RCI R- P \060\RP -Site Develop WP- ver- 03.doc 12 • 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 • 5i= 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 finding 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 • • —Z 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 done 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. J:\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 15 • • Geomatrix 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) 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 low areas using a bulldozer. 4. The graded materials will be covered as necessary to achieve final grade elevations using crushed, recycled concrete. J: \8769.000 RC1 R- P\060\RP -Site Develop WP- ver -03.doc 16 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 J :\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 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 • • Nf'= 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. 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. 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. ): \8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 19 P7 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 Geomatrix 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. 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. 1:\8769.000 RCI R- P\060\RP -Site Develop WP- ver- 03.doc 21 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. 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. 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. ):\8769.000 RCI R- P\060'RP -Site Develop WP- ver- 03.doc. 22 • :i %•- 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 stormwater 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 stored 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. 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 J:\8769.000 RCl R- P \060\RP -Site Develop WP- ver- 03.doc 23 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.

In April 2003, a significant interim action was undertaken at the site to provide hydraulic control of contaminated groundwater and limit the potential migration of contaminants into the Duwamish Waterway. This hydraulic control interim measure (HCIM) 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. (Rhodia); Bayer CropScience; and the U.S. Environmental Protection Agency, Region 10 (EPA), dated March 31, 1993, as amended in February 1999. The HCIM was completed in 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 followed by regrading and pavement of the western portion of the site. This redevelopment work will not adversely affect the recently completed interim measure. The property is being divided into two separate parcels (West and East Parcels) prior to redevelopment. The West Parcel will be developed on a different timetable from the East Parcel. The HCIM is wholly contained.within the West Parcel. While both parcels were part of former Rhone- Poulenc facility, the eastern portion of the facility was not been substanstially impacted by past operations. This work plan documents the past environmental site investigation data for the East Parcel and proposes cleanup for areas exceeding residential or unrestricted use cleanup levels. For those areas with insufficient information, additional investigation is proposed to collect additional data in order to determine the need for cleanup. 1.1 BACKGROUND The site occupies approximately 21 acres within 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 1946, J: \8769.000 RCI R -P \063 \Draft East Parcel CWP.doc 1 s* Geomatrix 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 1986 until Rhone- Poulenc ceased manufacturing'at the site in 1991. Rhone- Poulenc closed the site permanently in April 1991 and transferred the title of the property to Rhodia in January 1998. Rhodia sold the property in November 1998 to Container Properties, the current owner. Since site closure in 1991, investigations have been completed to evaluate environmental impacts to soil and groundwater. 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 the interim measure design. Quarterly monitoring of groundwater is conducted at the site; the Round 28 Quarterly Monitoring Report was submitted to EPA on August 25, 2005. The current property owner, Container Properties, moved forward with the HCIM 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? Container Properties has decided to proceed with redevelopment of the former Rhone- Poulenc site. Long -term redevelopment plans have not yet been finalized for the site; however, the site has been leased on occasion as a parking or storage lot. The West Parcel has been leased and is being redeveloped. Other parties may be interested in purchasing the East Parcel. During a meeting on August 15, 2005, Container Properties' representatives expressed the desire to try and remove the East Parcel from coverage under the Order. Currently, both the West and East parcels are covered by the Order; Container Properties would like to receive !: \8769.000 RCI R- P\063\Drafi East Parcel CWP.doc 2 Geomatrix clean RCRA closure without conditions for the East Parcel, and have it removed from the Order which would help facilitate the property lease or sale. A review of existing data indicates several sites in the East Parcel have soil data that exceed Model Toxic Control Act (MTCA) residential or unrestricted use cleanup levels. Container Properties proposes to excavate these identified areas, and this work plan outlines the proposed approach. In addition, this cleanup work plan proposes additional investigation for areas where existing data may be insufficient to determine the need for possible cleanup actions. 1.2 OBJECTIVES The primary concern for the East Parcel is the potential for contamination of soil and/or groundwater as a result of historical site practices. While the East Parcel has not been investigated to the same degree as the West Parcel, many soil and groundwater samples have been collected within the East Parcel. The objectives of the East Parcel cleanup work plan are to: • Summarize the historical and environmental data for the East Parcel for areas of potential concern. • Identify areas with "data gaps" where insufficient data exists to determine the need for possible cleanup actions. • Present a sampling and analysis plan for those remaining areas of potential concern without sufficient data and describe the methods that will be used to collect additional soil or groundwater data • Present a plan for cleaning up areas exceeding the applicable cleanup standards sufficiently to attain RCRA closure. Section 2.0 presents a summary of the historical soil and groundwater sampling results for the East Parcel, including discussion of the areas of potential concern in the East Parcel. Section 3.0 describes the scope of work for the East Parcel cleanup and investigation, while Section 4.0 describes the field and analytical methods. Section 5.0 discusses the schedule and the reporting for this work. 2.0 HISTORICAL SOIL AND GROUNDWATER DATA The former Rhone- Poulenc site has been investigated from 1986 through the present. The most relevant investigations for the East Parcel are: J: \8769.000 RCl R- P \063\Draft East Parcel CWP.doc Geomatrix • 1986 — Site Screening Investigation by Dames and Moore. • 1990 — RCRA Facility Assessment (RFA) by PRC Environmental • 1991 — Site Assessment by Landau Associates. This assessment was performed by Boeing prior to possible purchase of the facility. • 1995 — Final RCRA Facility Investigation (RFI) by CH2M HILL. • 1998 — Interim Measures Report-PCB Remediation and Sewer Cleaning by Rhodia. • 2001 — Geoprobe Investigation Report, Former Rhone- Poulenc Inc., Marginal Way Facility, Tukwila, Washington by AGI. Figure 2 is a composite figure incorporating two key figures from the 1986 Dames and Moore site screening investigation, and the subsequent RFA report. These figures highlight the solid waste management units (SWMUs) and other areas of concern in the East Parcel. The historical soil and groundwater sampling locations at the site are shown in Figures 3 and 4. Based on the areas within the East Parcel identified as SWMUs or areas of concern that are shown in Figure 2, there are approximatelytsix areas of interest in the East Parcel, including: • 'The former Maintenance Building and Storage Area. • The former Compressor Area. • The Laboratory Area. • The Sulfuric Acid Tank Waste Solids Disposal Area. • The Pilot Plant Waste Disposal Area. • The Background Area. Figures 5 and 6 show the copper concentrations in soil from 0 to 5 feet in depth, and greater than 10 feet in depth for the East Parcel. Figure 7 shows the other remaining metals exceeding the MTCA unrestricted use soil cleanup levels for unrestricted site use for the East Parcel. Those locations having organic soil analytical results exceeding the MTCA unrestricted use soil cleanup levels are shown in Figure 8. The following subsections describe each of these areas, their site history, the potential contaminants of interest, and the historical soil or groundwater sample results for these areas. While the figures compare the analytical results to MTCA Method A or Method B unrestricted use cleanup levels, the text in the subsections below and J: \8769.000 RCI R- P \063\Draft East Parcel CWP.doc 4 • Geomatrix This MTCA Method B cleanup level was calculated using the methods specified in the MTCA regulations (WAC 173- 340 -747). Appendix A contains a copy of the MTCA calculation described above. J: \8769.000 RCI R- P\ 063\Draft East Parcel CWP.doc 5 f Geomatrix at,a concentration of 20 mg/kg, which is above the MTCA Method A unrestricted use soil cleanup level. The soils in the former Maintenance Building area exceed the residential PRGs for arsenic at nearly every soil sample location with detectable concentrations: The PRG for arsenic is very low in concentration at 0.39 mg/kg. For the Puget Sound region, Washington State Department of Ecology (Ecology) has collected samples to determine natural background concentrations. For arsenic, the natural background concentration was determined to be 7.3 mg/kg (based on the 90`h percentile of the arsenic concentration distribution) (Ecology, 1994). Many of the reported arsenic concentrations are near this concentration, and many of the higher results were flagged for quality control purposes. It should also be noted that the site is downwind of the former Asarco lead smelter near Tacoma, and arsenic concentrations in surficial soils of the, Burien area are elevated above the natural background concentration similar to the range of arsenic values reported for the samples collected at 0.5 feet in depth. Vanadium was detected above the residential PRG value at 87.8 mg/kg, but below the MTCA unrestricted soil cleanup value for vanadium of 2,200 mg/kg. Natural background concentrations were not established for vanadium. Of the organic compounds in the area of the former Maintenance Building, only sample location F2 exceeded the MTCA Method A cleanup level for total PAHs of 0.1 mg/kg (or 100 µg/kg) as Benzo(a)pyrene (BaP) equivalents. The soil sample at F2 from 7.5 feet in depth contained 0.83 mg/kg of PAHs as BaP equivalents. This sample also exceeded the residential PRGs for BaP itself of 0.062 mg/kg (or 62 gg/kg). 2.2 FORMER COMPRESSOR AREA The former Compressor area includes the area of the former autoclave compressor which was located approximately 120 feet west of the existing laboratory building. The compressor area was listed by Dames and Moore as a separate area of concern, as shown in Figure 2. The Compressor area was not considered a SWMU during the RFA; however, leaks of compressor fluids were noted as part of the Satellite Accumulation Area or laboratory. The compressor fluid used was reported to be Pydraul A, a mineral oil carrier with polychlorinated biphenyls (PCBs) formerly manufactured by Monsanto. Aroclor 1254 was the PCB mixture present in Pydraul A compressor lubricants. J: \5769.000 RCI R- P \063\Dratt East Parcel CWP.doc. 6 v/..4k= Geomatrix Approximately six soil sample locations have been sampled near the former compressor area, and 16 confirmation samples were collected within an excavation immediately around the former compressor pad. ',Table 3 lists the soil analytical results for analytes reported above the limit of detection associated with the former compressor area. Only one groundwater sample was collected in this area at location B14. Table 4 lists the groundwater analytical results associated with the former compressor area. Samples collected near the former compressor pad at sample location A3 -02 contained copper , at ,a depth of 6 inches'with a concentration of 485 mg/kg. This exceeded the MTCA Method B cleanup level that is protective of marine water for unrestricted site use of 263 mg/kg (see footnote #1 in Section 2.1 for discussion of this calculation). Subsequent to the RFA, Rhodia performed a cleanup of the compressor pad in March and April of 1995. The compressor pad had been stained to a reddish/pinkish color to a depth of two inches, indicating potential contamination with compressor oil (Rhodia, 1998). The compressor pad and surrounding soil were excavated to a depth of 8 feet from an area measuring approximately 16 feet by 19 feet. A total of 16 confirmation samples were collected from the sidewalls and base of the excavation. Only two of the samples contained PCBs above the detection limit. Perimeter sample location PE -2A contained 1.93 mg/kg of total PCBs, while perimeter sample location PE -7A contained 2.42 mg/kg of Aroclor 1254 (Rhodia, 1998). The PCB cleanup level used for the cleanup was based on industrial site use and was 10 mg/kg of total PCBs. The MTCA Method A cleanup level for total PCBs for unrestricted site use is 1.0 mg/kg. Therefore the soils at PE -2A and PE -7A exceed the MTCA Method A unrestricted site use soil cleanup level for PCBs. The soil in the former Compressor area exceeded the residential PRGs for arsenic at A3 -02; however, the reported concentration of 2.8 mg/kg of arsenic is below the background concentration of 7.3 mg/kg. 2.3 LABORATORY AREA During the Dames and Moore Site Screening investigation, the area immediately west of they existing building was reportedly used for one -time disposal of vanillin black liquor solids (VBLS) in 1979 (PRC, 1990). The laboratory and the satellite accumulation area adjacent to it were identified as SWMU #5 during the RFA. Figure 2 shows the location of the VBLS disposal area, and SWMU #5. According to the RFA, the laboratory used methylene chloride for extractions during analysis. The spent methylene chloride was stored at the satellite J:\8769.000 RCI R -P \063 \Draft East Parcel CWP.doc 7 1 Geomatrix J: \8769.000 RC1 R- P\063\Draft East Parcel CWP.doc 8 Geomatrix 2.5 FORMER PILOT PLANT WASTE DISPOSAL AREA Dames and Moore identified this area as having been used for disposal of pilot plant. wastes (see Figure 2). According to the report of the Site Assessment investigation performed by Landau Associates, I.F. Laucks Company operated a pilot plant at the site that was used to make glue for plywood manufacturing (Landau, 1991). No other mention of pilot plant wastes was documented in the RFA or RFI report. It is assumed that wastes from the pilot plant operated by I.F. Laucks were the wastes that were reportedly disposed in this area. This area was used as an asphalt parking lot for the Rhone- Poulenc facility from the 1950s through closure of the plant. Four soil sample locations were located in this area to determine the potential for contamination associated with the disposal of pilot plant wastes. Table 8 lists the soil analytical results above the limit of detection associated with the pilot plant waste disposal area. Two direct -push groundwater samples were collected in the pilot plant waste disposal area, and Table 9 lists the groundwater analytical results for these samples. None of the samples collected in the former pilot plant waste disposal area exceeded MTCA Method A soil cleanup levels, with the exception of cPAHs in soil samples from sample locations D1 and ABG -06. A soil sample from location DI at 7.5 feet in depth exceeded the MTCA Method A cleanup level for total PAHs of 0.1 mg/kg as BaP equivalents. A soil sample from location ABG -06 at approximately 1.25 feet in depth also exceeded the MTCA Method A cleanup level for total PAHs of 0.1 mg/kg as BaP equivalents. The soil sample at DI contained 0.179 mg/kg of PAHs as BaP equivalents, and the sample from ABG -06 contained 0.106 mg/kg of PAHs as BaP equivalents. None of the groundwater sample analytical results exceeded the MTCA Method A groundwater cleanup levels. As in the case of the other areas, arsenic was detected at concentrations exceeding the residential PRGs in many of the soil samples. Three out of four of these results were lower than the natural background concentration of 7.3 mg/kg, and one was just above at 9.5 mg/kg. BaP also exceeded the residential PRGs in samples from sample location D1 and ABG -06 at 130 mg/kg and 87 pg/kg, above the PRG level of 62 pg/kg. The BaP PRG is 62 gg/kg. Aroclor 1254 was just above the PRG for PCBs of 0.22 mg/kg. J: \8769.000 RCl R- P \063\Draft East Parcel CWP.doc 9 Afek= Geomatrix 2.6 BACKGROUND AREA The Background Area of the East Parcel was not identified as an area of concern during the- earlier investigations. This area of the facility was occupied by the Italian prisoner -of -war camp during the mid- 1940s. ,During operation of the Rhone- Poulenc facility, this area was used primarily for parking of vehicles. From 1998 through 2004, the Background Area was used for temporary storage of trailer - mounted cargo containers. Thirteen soil sample locations were sampled in the Background Area. Three groundwater monitoring wells were installed in this area; one pair of groundwater monitoring wells, DM -1A and DM -1B, were installed in a cluster. DM -1B is a deep aquifer monitoring well. Groundwater monitoring well E3 was installed in the extreme southeastern corner of the site. Table 10 lists the soil analytical results above the limit of detection associated with the Background Area. Table 11 lists the groundwater analytical results associated with this area. None of the samples collected in the Background Area exceeded MTCA Method A soil cleanup levels. Formaldehyde was detected in RFI soil samples collected in the Background Area at concentrations up to 15 mg/kg, which is below the MTCA Method B unrestricted use soil cleanup level of 33 mg/kg. There are no established federal or state surface water cleanup levels for formaldehyde; the 50% lethal dose (LD50) in water for flathead minnows is between 38 to 48 mg/L. Using 19 mg/L as a maximum concentration in surface waters, the soil concentration that is protective of surface waters was calculated using the MTCA "Workbook for Calculating Cleanup Levels for Individual Hazardous Substances "; the calculated soil cleanup level is 76 mg/kg. Therefore, the formaldehyde concentrations detected in the soil in the Background Area are below unrestricted soil cleanup levels. Appendix A contains a printout of the MTCA workbook calculation described above. As with the other areas at the site, arsenic was detected above the residential PRGs at concentrations exceeding the residential PRGs; like the other areas nearly all of these exceedances were below the natural background concentration of 7.3 mg/kg for arsenic, and the highest arsenic soil concentration was 10.4 mg/kg in a soil sample collected at ABG -03. None of the groundwater sample analytical results exceeded the MTCA Method A or B groundwater cleanup levels for unrestricted site use. J: \8769.000 RCI R- P \063\Draft East Parcel CWP.doc 10 Geomatrix 3.0 EAST PARCEL CLEANUP AND INVESTIGATION ' Table 12 summarizes the proposed East Parcel scope of work for cleanup or investigation based on a review of the historical data for each of the six areas outlined above. Table 12 includes the rationale behind the recommendations for cleanup or investigation for the six areas discussed in Sections 2.1 through 2.6. As discussed in Table 12, cleanup actions are recommended for selected portions of: • The former Maintenance Building and Storage Area. • The former Compressor Area. • The Laboratory Area. • The Pilot Plant Waste Disposal Area Figure 9 contains a summary of the analytical data exceeding unrestricted . use soil cleanup levels and shows the approximate location of the proposed cleanup actions within areas. Table 12 outlines the general scope of the cleanup actions for each of these areas. The overall cleanup approach will be: • For areas where the exact location of the original soil sample is uncertain, the best estimate of the original location will be estimated and confirmed using a simplified sampling approach. • If none of these initial samples confirm sample result from the earlier investigation, then the original result will be considered unconfirmed and no further sampling or soil removal will be done. • If the sample results of the original investigation are confirmed, selected volumes of soil from the confirmation sample location will be removed. • If the historical sample location can be accurately determined using historical drawings or relations to existing structures, then soil removal will be performed. The soil exceeding the unrestricted cleanup level will be removed. • Soil confirmation samples will be collected from the base and sidewalis at each of the soil removal excavations. Because the exact locations of some of these earlier samples were not surveyed, there is some uncertainty in re- locating them precisely. Locations have been determined as accurately as J: \8769.000 RC1 R -P \063 \Draft East Parcel CWP.doc 11 Geomatrix possible by referring to historical maps and the location of existing structures. For those areas where the exact location is unknown, the following approaches will be used: • Locate each of the sample locations using a survey -grade Global Positioning System (GPS) unit capable of determining positions within 2 feet using a U.S. Coast Guard radio beacon correction. • A stake or mark will be used to locate the center of the targeted test pit grid (as shown in Figure 10). Five sample locations will be staked out in the cardinal directions (N, E, S, W) as measured from the GPS location of the original sample. • Five test pits will be excavated to the depth of the original sample, and soil samples will be collected for the same constituent that exceeded the unrestricted use cleanup level at that location. • The excavated soil and test pits will be covered with 20 -mil polyethylene sheeting to minimize contact with rainfall. • If all of the samples collected from these five targeted test pits do not exceed the respective unrestricted use soil cleanup level, then the original exceedence will be considered unconfirmed, and the test pits will be backfilled with the original soils and recompacted. • If the samples collected from the targeted test pits exceed the unrestricted use cleanup level for the original constituent of concern (COC), then an area measuring 5 feet by 5 feet will be excavated to 0.5 foot beyond the depth of that test pit sample and removed. • Four sidewall soil samples and one bottom sample will be collected as confirmation soil sample analysis. • The excavated soil will transported offsite for disposal in accordance with all state and federal regulations. The excavation will be filled with imported clean structural fill and recompacted. Targeted test pits will be used to address the uncertainty associated with locating the prior sample locations. If the confirmation samples exceed the unrestricted use cleanup level for the original COC, then additional soil will be excavated and removed until the confirmation samples are below the unrestricted use cleanup level. Table 13 lists the analytical methods that will be used for the targeted test pits and the soil confirmation cleanup samples. J:\8769.000 RCI R- P \063\Draft East Parcel CWP.doc 12 1 Geomatrix For the three sample locations which can be verified (PE -2A, PE -7A and B12), targeted test pits will not be used, and the soils at these locations will be removed using the soil removal procedures outlined above. 3.2 FORMER SULFURIC ACID TANK WASTE DISPOSAL Additional investigation is proposed for the Sulfuric Acid Tank Waste Disposal Area to determine if disposal of acidic wastes in this area have affected the soils. Figure 9 shows the location of the soil samples proposed for this area. Four soil samples will be collected from two sample locations. Samples from 1 foot and 4 feet in depth will be tested for lowered pH, and if acidic soil is identified, the elevated soil samples will be analyzed for total metals. No cleanup actions are proposed for this area unless elevated pH or metals analytical results are found that exceed the MTCA Method A or B unrestricted use cleanup levels. 3.3 BACKGROUND AREA No further cleanup or investigation of the Background Area is proposed. The existing soil and groundwater data for this area is sufficient, and cleanup or additional investigation is not warranted based on the existing historical and environmental data. 4.0 METHODOLOGY This section describes the methods that will be used to cleanup affected soils and collect soil confirmation or investigation samples during implementation of the East Parcel Cleanup Work Plan. Section 4.1 describes the cleanup methods and approach, while Section 4.2 describes the soil confirmation or investigation sampling methods. 4.1 CLEANUP METHODOLOGY The basic approach to the soil removals will be similar for the different areas excavate affected soils from around each of the sample locations that exceed MTCA Method A or B residential or unrestricted use soil cleanup levels. The soils will be excavated to at least 0.5 foot below the depth of the original sample result. The soils will be excavated by an excavator or backhoe, and the sidewalls will be kept as vertical as possible to reach the total depth of the excavation. The excavated materials will be stored temporarily in a stockpile next to the excavation. A layer of 20 -mil thick polyethylene sheeting will be placed under the stockpiles. Samples of the stockpile materials from each area J: \8769.000 RCI R- P \063\Draft East Parcel CWP.doc 13 • Geomatrix secured over the stockpile while the disposal characterization results are being analyzed. A vibratory compactor will be used to recompact the clean structural fill material used to backfill the soil removal excavations. The:backfill material will be placed in the test pit in 8- to, 12 -inch lifts and compacted. The original asphalt pavement near the excavation will not be restored because the site will be undergoing redevelopment and re- paving in the near future. Figure 9 shows the approximate location of the proposed cleanup actions in the East Parcel. Confirmation soil samples will be collected from the base and sidewalls of each cleanup excavation. The five confirmation samples will be collected from the lower sidewalls of excavations using the backhoe or excavator bucket. Table 13 lists the samples to be collected for each material encountered during the investigation. Table 14 lists the analytical methods that will be used, the reporting limits, the sample containers, preservation methods and holding times. If samples are collected for chemical analysis, samples for non -VOC analysis will be homogenized in a pre - cleaned stainless steel bowl and aliquots of the soil will be put into glass sample jars. While no samples are currently anticipated to be collected for VOCs, any sample collected for VOC analysis will be collected using EPA Method 5035 techniques, including use of 40- milliliter (mL) glass vial sample containers, and direct, immediate, sample collection from the excavator bucket or walls of the excavation. Samples for VOC analysis will not be homogenized prior to collection. The Geomatrix field geologist and the supervising geologist will be responsible for noting any changes in sampling methods caused by sampling difficulties, and all field observations will be recorded on the test pit logs or in the field logbook. The excavator bucket will be cleaned prior to conducting excavation at the site and decontaminated between the test pit or soil removal excavations in a given area. If waste materials are encountered in a test pit, the excavator will be decontaminated prior to conducting any new test pits. The excavator will be decontaminated prior to leaving the site. Decontamination will be done by high - pressure washing on a constructed polyethylene -lined pad to contain overspray. The soil sampling equipment will be decontaminated prior between samples using a three -step wash/rinse cycle. Water containing a dilute solution of Alconox will be sprayed onto the J: \8769.000 RCI R -P \063 \Draft East Parcel CWP.doc 14 Geomatrix shovel, bowl, and spoon, and scrubbed with a brush. Overspray and drippings will be contained in a 5- gallon polyethylene bucket. A second spray of Alconox solution will be used to remove soil from the sampling equipment. A third spray of deionized water will be used to rinse the equipment. All sampling equipment that is not intended to be used immediately will be wrapped in a layer of aluminum foil to minimize inadvertent recontamination. The decontamination fluids in the bucket will be decanted from the solids and treated using the existing on -site purge water disposal system following methods specified in the existing Operations and Maintenance manual. The solid material will be returned to the test pit where the sampling equipment was used. The analytical methods, sample volumes, sample containers, and maximum hold times are listed in Table 14. 4.2 SAMPLING HANDLING AND CUSTODY All analytical samples will be collected and stored in laboratory- supplied pre - cleaned bottles labeled using laboratory- supplied labels. Analytical samples will be stored in a cooler with water ice and kept cool until the samples are delivered to the laboratory or picked up by the laboratory courier. Standard chain -of- custody procedures will be followed using the laboratory- supplied chain -of- custody forms for all samples sent to the laboratory. Samples will be stored at the laboratory following the laboratory storage procedures prior to analysis. 4.3 ANALYTICAL METHODS Analytical samples may be analyzed for total metals, semi - volatile organic compounds (SVOCs), PCBs, pH, and/or hydrocarbons. Table 13 lists which analysis and methods will be run for each soil sample, and Table 14 lists sample volumes, sample containers, and maximum hold times for samples that may be collected as part of the investigation. Any analytical data will be reported with a standard laboratory data and quality control package. 4.4 QUALITY CONTROL Field duplicates will be collected at the rate of two field duplicates for every 20 samples or a 10% frequency. Field blanks will be collected at 5% frequency using analyte -free silica sand poured into the cleaned sampling or excavator bucket. Matrix spike or matrix spike duplicate (MS/MSD) samples requested are to be run by the laboratory on these samples. The standard laboratory control samples and quality control (QC) limits will be sufficient for this investigation. 1:18769.000 RCI R- P\0631Drafl East Parcel CWP.doc 15 Geomatrix 4.5 INSTRUMENT /EQUIPMENT TESTING, INSPECTION, AND MAINTENANCE No instrument/equipment testing, inspection, or maintenance will be required for this investigation. 4.6 INSTRUMENT CALIBRATION AND FREQUENCY The only instrument requiring calibration used during this investigation is the photoionization detector (PID), which will be calibrated using 100 parts- per - million isobutylene gas prior to the start of work each morning and then checked against the same standard at the end of each day for drift using the same standard. 4.7 INSPECTION /ACCEPTANCE OF SUPPLIES AND CONSUMABLES The field geologist will be responsible for inspecting all supplies and consumables; the field geologist will be responsible for determining if these materials are acceptable for use. 4.8 NON - DIRECT MEASUREMENTS No other non - direct measurements (such as computer databases, programs, or historical data) are anticipated to be required prior to the start of the pre - demolition investigation field activities. 4.9 DATA MANAGEMENT Standard laboratory deliverables and electronic data deliverables (EDDs) will be sufficient for this investigation. The data quality will be reviewed using the standard laboratory quality control information reported with the standard data package. 5.0 SCHEDULE AND DELIVERABLES 5.1 SCHEDULE The East Parcel Cleanup needs to be completed prior to completing the planned demolition and redevelopment of the site. The investigation activities are currently scheduled to occur in December 2005, pending EPA approval of this work plan The investigation report will be prepared and submitted to EPA within 6 weeks after completion of the field activities in order to receive any disposal manifests and analytical results. 5.2 DELIVERABLES The East Parcel Cleanup Report will summarize and document the °field activities, including field observation logs, photographs, and the soil analytical results. The report will document ): \8769.000 RCI R- P\063 \Dlaft East Parcel CWP.doc 16 ✓: Geomatrix the results of the individual soil removals completed as part of the work plan activities, and document the volume and mass of soil removed from the site, as well as the disposal manifests. 6.0 REFERENCES AGI, 2001, Summer 2001 Geoprobe Investigation Report, October.

Targeted test pits will be used to determine if the soils near these locations requires soil cleanup due to the constituents of concern noted at these locations. - • All three locations will be test -pitted and sampled in 5 places in a cubic grid as shown on Figure 10. • Sample location sA3 -05 and A3 -08 will be test -pitted to a depth of 2 feet and the five samples at each area will be submitted for total metals. 1 • The best -pits at location F2 will extend 7.5 feet below ground, and the samples analyzed for cPAHs. • If a test pit grid sample exceeds the appropriate MTCA Method A or B unrestricted use soil cleanup level, a 5 -foot by 5 -foot grid will be excavated and removed. • At each location 5 confirmation samples will be collected (4 sidewall samples, 1 bottom) to confirm that the cleanup is complete. Former Compressor Area No Yes • Past cleanup activities have addressed the majority of the PCBs released at the former compressor pad. Existing data are sufficient to rule out the need for additional soil or groundwater investigation. • A soil cleanup action is proposed for past soil sampling location A3 -02. Targeted test pits will be used to determine if the soils near this location requires soil cleanup due to the constituents of concern noted earlier at this location. • A soil cleanup action is proposed for past soil sampling locations PE -2A and PE -7A. These samples were collected at the base of an earlier excavation as part of the compressor cleanup. Since the location of the compressor pad is known from facility drawings, the soil removal will occur without the use of test pits. • The A3 -02 location will be test -pitted and sampled in 5 places in a cubic grid as shown on Figure 10. • The test pits will extend to 0.5 feet to 1.0 feet in depth. Samples from the test pits will be analyzed for total metals. • Sample locations PE -2A and PE -7A located near ;former compressor pad whose location can be determined based on historical drawings. No targeted test pits will be used. • Soil from two areas measuring at least 5- feet by 5 -feet will be excavated around sample locations PE -2A and PE -7A. • The PE -2A and PE -7A excavations will extend to approximately 8 -feet in depth. • Soil confirmation samples will be collected at the bottom of these two excavations and all four sides.

ATTACHMENT Safety Plan Compliance Agreement i.r Health and Safety Plan Page 1 1.0 INTRODUCTION The health and safety (H &S) requirements for Geomatrix employees performing activities described below at the former Rhone- Poulenc Site are provided in this Health and Safety Plan (HSP). 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. 1.1 PURPOSE 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 CPR 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.

In addition, the HSM will perform the following activities: • Plan, organize, direct, coordinate, review, and evaluate the Geomatrix health and safety program; • Supervise the employee health and safety training program; • Advise on matters of health and safety and provide recommendations for solving health and safety problems; • Review and approve all site safety plans and modifications; and If warranted, evaluate site operations to ensure compliance with the site HSP and take corrective actions when necessary. 2.2 PROJECT MANAGER: The project manager (PM) will monitor all site operations and project implementation. In addition, the PM will perform the following activities: • Ensure that adequate resources are available to implement and carry out all site safety activities; • Ensure that all personnel assigned to the site receive all necessary health and safety training; • Familiarize all on -site personnel with site safety requirements; • Assign key safety duties and responsibilities to team members; • Ensure that all necessary PPE (including respiratory) is available and on site; and • Enforce the health and safety requirements specified in this plan. H:\RCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP \RedevelopmentHASP -ver -0l .doc Health and Safety Plan Page 6 2.3 SITE COORDINATOR/ SITE HEALTH AND SAFETY OFFICER: The site coordinator (SC /SHSO) shall implement this HSP, act to correct any safety deficiencies, and help select PPE, ensure that it is approved by the HSM, and that it is on site and properly used. The SC /SHSO will also perform for the following activities: • Ensure that on -site inventories can adequately support operations and site visitors; • Maintain a field log of all site visitors. • Maintain-exposure /injury reporting and documentation and on -site health and safety record keeping; • Assist supervisory personnel when investigating all accidents and exposures to determine the cause, and make recommendations to prevent recurrence of the incident; • Conduct on -site air monitoring and appropriate sampling to ensure compliance with appropriate action levels; • Verify that necessary safety and PPE is available and properly used; • Suspend site activities if conditions arise that present inuninent danger to site personnel or visitors; the SHSO shall immediately notify the HSM and PM following the suspension of work; • Inform local emergency facilities about the nature of work being performed, . dates and times of site activities, and possible injury types; • Maintain a health and safety activities in the logbook to record all field measurements, site activities, and decisions that might alter the HSP; • Conduct weekly health and safety meetings that shall include reviewing activities and hazard analyses; and • Document weekly health and safety meetings including date, attendance, and subjects discussed. HARCI - 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 bloodbome 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 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 HEPA/P100 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 -0l.doc Health and Safety Plan Page 12 • 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. 4.4.3 Noise 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:tRCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov 05\Appendix F- HASP\ RedevelopmentHASP- ver -01.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. lockout/tagout) 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\Redeve lopmentHASP- 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°F. 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 -0l.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 Health and Safety Plan Page 16 place following maintenance and repair work. Warning signs will be posted at all machine guards indicating that personnel are not to operate the equipment unless guards are in place. 4.4.12 Project Hazard Analysis This work involves the use of heavy equipment used for earth moving and other equipment commonly used during construction activities. 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. r ' ,r �-` .Task, = Chem , "'- Hzds. • Heat! ,Gold ' Stress : - .• I Noise Slip/ . ;Trip /. ` Fall: Lifting; Ilzds. : .Mech'l.. - -Hzds. - Electra 7- cution , Explosion - ::Ezcav -- • ation 1.

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 -0l .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; HARCI - RP Site Redevelopment\Site Redevelopment Work Plan Nov O5\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 torn 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, 5511 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 Health and Safety Plan Page 21 5.5.3 Decontamination — Medical Emergencies 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 PID (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.

APPENDIXES Appendix A Best Management Practices from the Western Washington Stormwater Management Manual H:\S769 005 - SWPPP FOR DEMO +GMX SWPPP FOR CP DRAFT TRENCHING ONLY DOC 1.0 INTRODUCTION Construction activities, including trenching and building construction will be performed at the former Rhone- Poulenc, Inc. (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 Storm pater 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 RN 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:18769 005 - S WPPP'for DcmotiGMX SWPPP for CP Draft trenching only doe 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. Stormwater 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 corner 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 Stormwater Management Manual 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. H:18769 005 -SWPPP for DcmoNGMX SWPPP fm CP Draft trenching only doc 2 • • 4.4 INSTALL SEDIMENT CONTROLS The trenching for the electrical service is anticipated to occur prior to October 15t, 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 1g, 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 Stonnwater 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. I1:W69 005 - SWPPP for DcmotGMX SWPPP for CP Draft trenching only Ea 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 Stormwater 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 Demo1GMX SWPPP for CP Drafi trenching only don 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 Stormwater 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:\8769 005 . SWPPP for Demo' MX 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 Stormwater 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 Stormwater Management Manual. for Western Washington, Volume H (February 2005) (see Appendix A). 4.10 CONTROL DR-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 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 Stormil'ater 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 1, 2005 for approximately a two -week period.

MTCASGLIO- Zinc.XLS . 11/28/2005 • • Geomatrix APPENDIX A Best Management Practices from the Western Washington Stormwater Management Manual BMP C123: Plastic Covering Purpose Plastic covering provides immediate, short -term erosion protection to slopes and disturbed areas. 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 hydroseed 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 $150.2.00 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 Stormwatet Pollution Prevention • February 2005 • Design and • Plastic slope cover must be installed as follows: installation I. Run plastic up and down slope, not across slope; Specifications 2. Plastic may 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 likely, 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.

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 • Hazardous chemicals such as acids, lime, adhesives, paints, solvents and curing compounds • Any other material that may be detrimental if released to the environment Design and The following steps should be taken to minimize risk: Installation Temporary storage area should be located away from vehicular traffic, • Specifications near the construction entrance(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. February 2005 Volume Il — Construction Stormwater 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, or 302 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, plus 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 stored 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 -Oil Absorbent Socks 3 "x 4' • 2 -Oil Absorbent Socks 3 "x 10' • 12 -Oil Absorbent Pads I T'x I.9" • 1 -Pair Splash Resistant Goggles • 3 -Pair Nitrite Gloves • 10-Disposable Bags with Ties • Instructions 4-46 Volume 11— Construction Stomrwater Pollution Prevention February 2005 BLIMP C220: Storm Drain Inlet Protection Purpose To prevent coarse sediment from entering drainage systems prior to permanent stabilization of the disturbed area. 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.

February 2005 Volume II — Construction Stomiw -ater 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 leaned 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 II — Construction Stomiwater Pollution Prevention February 2005 BMP C233: Silt Fence Purpose Conditions of Use 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. 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 03 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. Joins in titer fabric shaD be spiced at posts.

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 Zfi 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 II — Construction Stonnwater 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 shall 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.

The spacing of the support posts shall be a maximum of 6feet 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 4.20 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 close 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. February 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 in 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.

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 J:'8769.000 RCI R- PW261Pretreat Relocate Package.ver -03 ats.doc 2 • • GEOMATRIX 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; 1:18769.000 RCI R -P O261Ptctrcat Rclocatc Package -ccr -03 als.doc 3 GEOMATRIX • 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- P'.026Wrctrcat Relocate Pad age.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 western 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). J:tg769.00O RCI R- P1036\Prcucat Rclocatc Package-ref.-03 als.doc 5 • • GEOMATRIX 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:t8769.000 RCI R- P1026 \Pretrcat Relocate Package- vcr-03 als.doc 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 I, 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:\8769,000 RCI R- P1036\Pretreat Relocate Package- vcr.03 als.doc 7 • • GEOMATRIX 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 3:8769.000 RCI R- P■026V'regeat Relocate Package-me-03 als.doc • • 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. J:18769.000 Rd R- P1026\Prctrcat Relocate Packagc•ver-03 ak.dac 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 electrical/communication 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. 1:18769000 RCI R- P\026Wrctrcu Relocate Package-ea-03 alsdoc 10 • • GEOIVIATRIX 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 l:t8769.000 RC!

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 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. �N'O�— 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 specifically 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 1 I 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 Part D: Please review each question below for projects that include work below the ordinary high water mark of watercourses or the Duwamish/Green or Black Rivers or in wetlands. 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. 3 -1 Will the project involve the direct alteration of the channel or bed of a watercourse, the Green/Duwamish rivers, or Black River? For the purpose of this analysis, channel means the area between the ordinary high water mark of both banks of a stream, and bed means the stream bottom substrates, typically within the normal wetted -width of a stream. This includes both temporary and permanent modifications. Please circle appropriate response. NO - Continue to Question 3 -2 YES - Continue to Question 3 -2 3 -2 Will the project involve any physical alteration to a watercourse or wetland connected to the Green/Duwamish River? For the purpose of this analysis, "connected to the river means" flowing into via a surface connection or culvert, or having other physical characteristics that allow for access by salmonids. This includes impacts to areas such as sloughs, side channels, remnant oxbows, ditches formed from channelized portions of natural watercourses or any area that may provide off channel rearing habitat for juvenile fish from. the Duwamish. River. This includes both temporary construction alterations and permanent modifications. Watercourses or wetlands draining to the Green/Duwamish River that have a hanging culvert, culvert with a flap gate, diversion, or any entirely man-made or artificial structure that precludes fish access should answer Yes to this question. Please circle appropriate response. NO - Continue to Question 3 -3 YES - Continue to Question 3 -3 3 -3 Will the project result in the construction of a new structure or hydraulic condition that could be a barrier to salmonid passage within the watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, a barrier means any artificial or human modified structure or hydraulic condition that inhibits the natural upstream or downstream movement of salmonids, including both juveniles and adults. Please circle appropriate response. NO - Continue to Question 3-4 YES - Continue to Question 3-4 3 -4 Will the project involve a temporary or permanent change in the cross - sectional area of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, the cross - sectional area is defined as a profile taken from the ordinary high water mark on the right bank to the ordinary high water mark on the left bank. Please circle appropriate response. NO - Continue to Question 3 -5 YES - Continue to Question 3 -5 3 -5 Will the project require the removal of debris from within the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, debris includes, but is not limited to fallen trees, logs, shrubs, rocks, piles, rip -rap, submerged metal, and broken concrete or other building materials. Projects that would require debris removal from a watercourse or the Green/Duwamish or Black Rivers as part of a maintenance activity should answer Yes to this question.

The applicant is not aware of geotechnically unstable soils on the site or in the immediate vicinity. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. A very small amount of grading is necessary to relocate the groundwater pre- treatment system associated with the hydraulic control interim measure, and demolition of existing pavement and buildings for repaving and a new storage building. All graded or demolished surface material (asphalt, soils, and concrete) material will be kept on site and used for pavement subgrade or other use. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. g. The site is protected from sediment leaving the site to the west by existing slurry walls that contain all stormwater. Some erosion could occur as a result of construction activities due to removal of existing pavement and the minimal grading. Temporary erosion and sedimentation control (TESC) measures will be implemented prior to construction, which includes installing catch basin protection measures, silt control fences, and other Best Management Practices (BMPs) as required by the City of Tukwila. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? -4- I0265.005.doc [07/05/05] • • Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments The site will be covered with up to 90 percent of impervious surfaces. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: An engineered TESC plan will be prepared with final engineering documents for this proiect. TESC measures are expected to include catch basin protection inserts, silt fencing, standard strength fiber fabric, and other Best Management Practices that may be warranted. 2. Air a. What types of emissions to the air would result from the proposal (for example, dust, automobile odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Internal combustion engine exhaust and soil dust may be generated during construction. After construction, typical automobile emissions will result from activities in the proposed storage areas. b. Are there any off -site sources of emissions or odor that may affect your proposal?

Indicate the source of fill material. No fill or dredge material will be placed in or removed from surface water. 4. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. The project does not propose surface withdrawals or diversions. 5. Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. FEMA FIRM Floodplain Map No. 53033C0645 F (see Appendix) shows that the majority of the subject property is located within Zone X, which is outside of the 100 -year floodplain. A small portion of the property along the, Duwamish Waterway is.located within the floodway boundary. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. Treated stormwater runoff will discharge directly to the Duwamish Waterway since the project is located below the 6.3 -mile mark of the river. Water quality treatment will be required for the development of the site based on the 2005 King County, Washington Surface Water Design Manual (KCSWDM). -2- 10265.005.doc 107/05/051 • • Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments b. Ground: 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). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to. serve: The project does not propose to discharge waste material into the ground. c. Water Runoff (including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow? Will this water flow into other waters? If so, describe. Project- generated stormwater from the pavement and buildings will be directed to an on -site water quality treatment facility and discharged into the Duwamish Waterway. 2. Could waste materials enter ground or surface waters? If so, generally describe. The property contains an active Superfund site, which is subject to special requirements to ensure that waste materials from the site do not enter surface waters. The redeveloped site will cap the existing ground surface, which is expected to help reduce or eliminate stormwater penetration and seepage into the contaminated soils. Project generated waste materials are unlikely to enter the groundwater as stormwater from the repaved parking areas and buildings will be collected in a closed catch basin and pipe system that will be direct stormwater to an underground water quality vault prior to release in to the Duwamish Waterway. d.

No. The project will not affect the potential use of solar energy by adjacent properties. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: On -site storage yard lighting islinot proposed. The proposed storage building will be designed to meet the requirements of the Washington State Energy Code for glazing, insulation, etc. 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. As the property contains a Superfund site, exposure to hazardous materials is a risk during construction. As required by RCRA, the applicant's consultants will prepare an Operation, Monitoring, Inspection, and Maintenance Plan to be reviewed and approved by the EPA prior to redevelopment activities. Once the site construction activities are completed, environmental health hazards are not likely to be generated by the proposed storage yard and storage building. There is an existing system of groundwater extraction wells and a pre- treatment system to pump groundwater from -4- 10265.005.doc 107/05/051 Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments the contaminated area of the site. This system will be relocated with the redevelopment, however the functions will be continued. 1. Describe special emergency services that might be required. During construction, if workers are exposed to hazardous materials are, a hazardous waste or materials decontamination specialist may be necessary. Procedures for working near hazardous waste or materials will be outlined in the Operation, Monitoring, Inspection, and Maintenance Plan. 2. Proposed measures to reduce or control environmental health hazards, if any Site contractors will be provided with the Operation, Monitoring, Inspection, and Maintenance Plan and it is assumed that a plan will be retained on site throughout as well as after construction. The site redevelopment as proposed would effectively cap the surface to eliminate or reduce stormwater seepage that would contribute to off -site impacts from contaminants from the site entering the Duwamish Waterway. This, in combination with the continuation of the groundwater extraction and pre- treatment system, as well as the redevelopment of the site, is expected to reduce and control environmental health hazards and comply with local, state, and federal hazardous waste site requirements. b. Noise I. What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? The project is located in an area known as Seattle South End Industrial District. Noise in the surrounding area includes industrial noises of machinery, equipment, and trucks; automobile traffic on adjacent roadways; airplane traffic from King County Airport and SeaTac airport; and water traffic.
