Publication Date: August 10, 1998 Account No. 51067 dnspub STAFF City of Renton REPORT Department of Planning/Building/Public Works ENVIRONMENTAL REVIEW COMMITTEE A. BACKGROUND !' ERC MEETING DATE AUGUST 4, 1998 Project Name Puget Power Remediation Applicant Puget Sound Energy File Number LUA-098-094, ECF Project Manager Peter Rosen Project Description Proposal for remediation activities at the Puget Sound Energy Grady Way site. The proposal includes the removal of three underground fuel storage tanks and the removal and replacement of the stormwater system and the excavation and off-site disposal of contaminated soils associated with the stormwater system. Two existing 10,000 gallon underground storage tanks (UST) would be removed. The tanks were installed new in 1989 to current State standards and show no evidence of structural problems or leaks. A 2,000 gallon heating oil tank serving the west building on the site would also be removed. In addition to the tank removals, the stormwater system would be removed and replaced. As part of the stormwater system removal and replacement, approximately 1,000 cubic yards of soil material would be excavated, of which 600 cubic yards would need to be transported off-site for disposal. There are five other"hot spot" locations of soil contamination that are associated with the existing stormwater lines. At these five locations, approximately 300 cubic yards of soil would need to be excavated and transported off-site. There are two remaining soil contamination areas that are not associated with the stormwater system removal and replacement. At these two locations, a total of 170 cubic yards of soil would be excavated, of which 100 cubic yards would be transported off-site for disposal. The total estimated volume of soil excavation is approximately 2,030 cubic yards, with an estimated 1,000 cubic yards to be transported off-site for disposal. Puget Sound Energy will be required to remediate all soil contamination to the applicable Model Toxics Control Act (MTCA) standards. There is a drainage channel, listed as an unnamed minor watercourse, which flows across the south portion of the site. A wetland is located to the south of the drainage channel. The proposal would not impact the drainage channel or wetland. Project Location 620 Grady Way Exist. Bldg. Area gsf 90,000 sq. ft. Proposed New Bldg.

ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. Has the applicant adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development? 1. Earth Impacts: Approximately 80% of the site is presently developed and is fairly level with grades between 2% to 3%. The east portion of the site below Benson Road has slopes of approximately 40%, with 20% slopes on the portion of the site above Benson Road. The proposed remediation activities are on the flat, developed portion of the site and therefore would not impact the steep slope area. The remediation activities would include cleanup of localized soil contaminates that have been detected at concentrations exceeding cleanup levels. The applicant estimates the total volume of soil to be excavated to be approximately 2,030 cubic yards, with 1,000 cubic yards of contaminated soil to be transported off-site for disposal. Most of the contaminated soils (1,860 cubic yards out of 2,030 cubic yards) are associated with the removal and replacement of the stormwater system. Minor filling and grading is proposed. The source of fill is not presently known, but will be from a clean pit run. Grading of fill material would allow adequate compaction for future site development. Potential impacts of soil erosion during the remediation activities is expected to be minimal; phasing will minimize areas of exposed soils and potential impacts would be mitigated by measures in the temporary erosion and sedimentation control plan. Mitigation Measures: No further mitigation is recommended. Nexus: NA 2. Air Impacts: Emissions from construction equipment and dust from excavation and grading can be anticipated during the construction/remediation phase of the proposed project. Impacts during construction would include increased levels of airborne particulates (especially dust) from disturbance of exposed soils. Construction impacts would be short term in nature and would be mitigated through best management practices of the required Temporary Erosion and Sedimentation Control Plan (TESCP) and with the Construction Mitigation Plan. Measures that could be implemented, if needed, include spraying exposed soils with water or other dust suppressants during dry, windy weather. Emissions from construction equipment exhaust would have a minor impact on local air quality. Exhaust from construction vehicles is regulated by State and City Codes. Mitigation Measures No further mitigation is recommended. Nexus: NA 3. Water Impacts: There is an existing drainage channel, listed as an unnamed minor watercourse, that flows across the southerly portion of the site from east to southwest in an open concrete-lined channel. The proposal would not impact the drainage channel, only one small "hot spot" of contaminated soil (E-7) associated with the existing stormwater system) would be excavated in the area of the drainage channel. The Temporary Erosion and Sedimentation Control Plan (TESCP) indicates that silt fencing would be provided and together with the walls of the concrete fume would prevent sediments from entering the watercourse. The application includes an evaluation of the stormwater drainage channel, prepared by GeoEngineers, Inc., identifying the course and nature of the channel. Generally, the drainage channel collects stormwater and is both an open channel and piped along its course. It originates at the top of a ravine, southeast of I- ERCRPT.DOC City of Renton P/B/PW Department Environmental Review Committee Staff Report PUGET POWER REMEDIATION LUA-98-094, ECF REPORT OF AUGUST 4, 1998 Page 4 of 5 405, near the intersection of Grant Avenue South and South 18th Street, approximately 3,000 feet southeast of the subject site. The drainage carries stormwater partly in an above-ground channel (unlined) with occasional subsurface (piped) sections toward the bottom of the slope. The drainage channel enters a 3-foot-diameter steel culvert that directs the runoff beneath 1-405. The culvert daylights beneath 1-405 onto the east boundary of the subject site, discharging into a concrete sedimentation basin and then into the concrete-lined drainage channel across the subject site. The channel exits the southwest corner of the site through a 3-foot diameter culvert located beneath Talbot Road. Downgradient of the subject site, the drainage channel trends south along the west side of Talbot Road, and then west along the north side of South Renton Village Place. The stormwater channel ultimately is diverted south under 1-405, and discharged to Panther Creek wetland, then Springbrook Creek, Black River, and finally to the Green River. There is an existing wetland located in the southeast corner of the site. The wetland is located immediately adjacent to the concrete drainage channel. The area of the wetland is 41,475 square feet and Talasaea Consultants have classified the wetland as a Category 3 type wetland. The subject proposal would not have direct or indirect impacts on the wetland. No excavation is proposed in or adjacent to the wetland. The wetland is isolated from the developed area of the site by the concrete drainage channel. The erosion control plan would prevent sediments from entering the wetland. Category 3 wetlands require a minimum 25 foot buffer width. Excavation/remediation activities associated with removal and replacement of the stormwater system would occur within 25 feet of the wetland. Presently, there is no vegetated wetland buffer, as the developed area of the site comes right up to the concrete drainage channel which is the north edge of the wetland. The Wetland Ordinance exempts the maintenance and repair of existing utilities from wetland buffer requirements. The applicant plans to phase the remediation activities on the site to minimize the extent of disturbed and exposed areas on the site at any one time. The Temporary Erosion and Sedimentation Control Plan (TESCP) would be included as part of the project specifications. The plan would include the use of silt fencing, haybales or other measures to reduce runoff impacts. Vehicles would be decontaminated to remove dust and dirt before exiting the site. Mitigation measures for equipment and debris laydown areas would include use of plastic sheeting as a liner below the equipment and debris and for a covering as needed. Mitigation Measures No further mitigation is recommended. Nexus: NA 4. Environmental Health Impacts: A licensed contractor would remove the underground storage tanks and would be responsible for meeting all applicable City, State and Federal regulations pertaining to the removal of underground storage tanks. The tank removal will require permits from the Renton Fire Prevention Bureau. The contractor will be required to provide health and safety plans to specifically address tasks necessary to comply with applicable regulations. Existing regulations and standards would effectively mitigate potential environmental health impacts. A Draft Environmental Site Assessment (ESA), prepared by Hart Crowser, Inc., identifies the localized areas where contamination levels have been detected to exceed cleanup levels. The report indicates the locations and types and levels of contaminants detected. The site cleanup would be required to meet the applicable standards of the Model Toxics Control Act (MTCA). Approximately 1,000 cubic yards of contaminated soils would be removed from the site and transported to approved disposal sites. There is no on-site remediation of soils proposed. Mitigation Measures No further mitigation is recommended.

Transportation Impacts: It is estimated that 150 to 200 truckloads would be required to remove the tanks and contaminated soils from the site and bring in backfill material. Vehicles would be decontaminated to remove dust and dirt before exiting the remediation area. The applicant has submitted a Construction Mitigation Plan which indicates the hauling routes and measures to be implemented to minimize dust and traffic impacts. In order to limit the impact of trucking activities during peak traffic periods, truck hauling hours are limited to between 8:30 a.m. and 3:30 p.m. under the Development Guideline Ordinance. Mitigation Measures No further mitigation is recommended. Nexus: NA E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental / Divisional Reviewers for their review.

Box 97034 MER-04 Bellevue, Washington 98009-9734 Attention: Barry Lombard Stormwater Drainage Channel Evaluation Grady Way Complex Site Renton, Washington File No. 0186-407-00 This letter summarizes our evaluation of the stormwater drainage channel located on the southern portion of Puget Sound Energy's (PSE) Grady Way site in Renton, Washington. The purpose of this evaluation was to identify the course and nature of this drainage feature at off-site locations. We understand that this information will be used by the City of Renton for permitting purposes related to the proposed remedial project at the Grady Way site. We completed this evaluation by reviewing maps on file with the Surface Water Utilities group in the City of Renton's Public Works Department. We also interviewed Mike Dodson, an employee in the Surface Water Utilities group. Field reconnaissance also was conducted to verify information provided by the City of Renton. Our field reconnaissance was conducted along readily accessible portions of the subject drainage channel. Relevant maps provided by the City of Renton are enclosed with this letter. The course of the drainage channel and the approximate outline of PSE's Grady Way site are highlighted on the enclosed maps. The stormwater channel originates at the top of a ravine on a slope located southeast of I-405, near the intersection of Grant Avenue South and South 18th Street. The top of the ravine is located approximately 3,000 feet southeast of the Grady Way site. At this location, stormwater runoff from surrounding streets and parking lots is discharged to the top of the ravine/stormwater channel. The stormwater is directed to the ravine through a tightlined stormwater system, as shown on the enclosed map (see Sheet 1). Stormwater directed to the ravine generally tlows in a northerly direction in an above-ground channel (unlined) with occasional subsurface (piped) sections. Toward the bottom of the slope, the drainage channel enters a 3-foot-diameter steel culvert that directs the runoff beneath I-405. GeoEngineers,Inc.

Stormwater from the culvert is discharged to a concrete sedimentation basin constructed at this location. A second pipe (12-inch-diameter) also discharges water from an unknown source into the sedimentation basin. Stormwater flows from the sedimentation basin into a concrete-lined drainage channel located along the southeast boundary of the Grady Way Complex site. Near the southwest boundary of the site, water is discharged from the concrete-lined channel into an unlined channel. This channel exits the site by flowing into a 3-foot-diameter culvert located beneath Talbot Road. Downgradient of the subject site, the drainage channel trends in a southerly direction along the west side of Talbot Road (Sheet 2), then in a westerly direction along the north side of South Renton Village Place. Stormwater from developed properties in this area is directed to the subject drainage channel through subsurface piping. The subject drainage "channel" in this area exists primarily as an underground (piped) stormwater system, with one area of open-channel flow near 1-405. The stormwater channel ultimately is diverted to the south, under I-4O5, and discharged to Panther Creek Wetland, then Spring Brook Creek, Black River, and finally the Green River. Water flow between these surface water features is accomplished by piping and/or pumping. —4 ► Our services were performed at the request of Barry Lombard of PSE in accordance with our general agreement with PSE (contract number BXO1O74-CO1A).

The Grady Way property is approximately twenty acres and is currently used and zoned as industrial property. The proposed project name is Grady Way Complex Remediation Project. Site address: PSE's Grady Way Complex 620 Grady Way Site location: At PSE's Grady Way Complex. This site is located east of Talbot Road, south of Grady Way, and west of Primary State Highway No. 1 (I-405). It is approximately twenty acres and is currently used and zoned as industrial property. (See attached vicinity map) Q-S-T-R: SW 1/4 of Section 17 T. 23 N.R. 5E NE 1/4 of Section 19 T. 23 N.R. 5E NW 1/4 of Section 20 T. 23 N.R. 5E Current Use of Site and Existing Improvements Previous uses of the Grady Way Complex site have included transformer storage and maintenance, vehicle fueling and maintenance, and storage of power poles treated with wood preservatives. Approximately 3,750 cubic yards of soil containing residual concentrations of petroleum hydrocarbons associated with former underground storage tanks (USTs) and hydraulic hoists were successfully removed from the site between 1987 and 1990. Remaining petroleum hydrocarbon concentrations detected at the final limits of the hoist and UST remedial excavations were less than applicable cleanup levels. The site currently contains three buildings, three remaining USTs, a storm water drainage system, and electrical equipment and materials stored and used by PSE. There is a PSE utility storage yard on the south end of the site. A utility warehousing and former garage/fleet maintenance facility are located on the mid-westerly portion of the site. A transformer repair shop is near the middle of the site. Engineering offices and general utility storeroom supplies are housed in the easterly building. The remaining single story office building on the north portion of the site is vacant. (See attached site plan) Special Site Features A drainage channel, listed as an unnamed minor watercourse, flows across the southerly portion of the site from east to southwest in an open concrete-lined channel. There is also a wetland located on the property, south of the drainage channel and proposed project area. The wetland is outside of the improved fenced-in yard where the remediation work will occur. (See attached plan for location) Work will occur within 200 feet of drainage channel and wetland. The proposed project will not impact the drainage channel or the wetland. (See attached plan) Number and Location of Existing Structures and/or Residential Units Which Might Be Impacted By the Proposed Project None. Puget Sound Energy Grady Way Complex Remediation Project Project Narrative Proposed Action PSE proposes to remove two existing underground fuel tanks, 10,000 gallons each, shown on the Site Plan. The tanks were installed new in October 1989 to current Washington State Underground Storage Tank (UST) Regulation. They are in good condition without any evidence of structural problems or leaks. The USTs are being used for the storage of gasoline and diesel used to fuel company vehicles. These two USTs are constructed of double wall fiberglass with automatic leak monitoring. The excavation area for these two USTs is denoted as E-1 on the Excavation Plan (See Figure 3). In addition to the two USTs mentioned above, the heating oil UST for the westerly building on this site will be removed. This UST contains diesel fuel for the building heating boiler. PSE will remediate any contamination caused by this UST to applicable Model Toxics Control Act (MTCA) standards. The excavation area for the heating oil UST is denoted as E-2 on the Excavation Plan (See Figure 3). A qualified UST removal contractor licensed and experienced in the removal of USTs will remove the three fuel USTs. The contractor, in accordance with PSE's removal specifications, will perform the necessary removal and restoration activities, including any associated remediation. All appropriate City, State, and Federal regulations pertaining to the removal of USTs will be adhered to in addition to other applicable requirements. The contractor will be required to provide UST removal and health and safety plans to specifically address tasks necessary to comply with applicable regulations and ordinances. A work plan will also be required of the contractor and will be available for review at the site at all times while project activities are underway. In addition to UST removal activities, the storm water system will be removed and replaced. As part of the storm water system removal and replacement, approximately 1,000 cubic yards of material will be excavated, of which 600 cubic yards will be transported off site. The storm water system removal and replacement is denoted as E-10 on the Excavation Plan (See Figure 3). There are several locations where contaminated soil will need to be removed in conjunction with the storm water system removal and replacement. These are denoted as E-3, E-5, E-6, E-7, and E-8 on the Excavation Plan (See Figure 3). At these five locations, approximately 300 cubic yards of soil will need to be excavated and transported off site for disposal. There are two remaining excavation areas, E-4 and E-9 on the Excavation Plan (See Figure 3) that are not associated with the storm water system removal and replacement. At these two locations, a total of approximately 170 cubic yards of soil will be excavated, of which 100 cubic yards will be transported off site for disposal. The volume of soil excavation and fill not associated with either the storm water system removal and replacement or UST removal totals less than 500 cubic yards. The following, from a report by GeoEngineers, provides details on the remaining contamination on the site: The results of the recently completed Draft Environmental Site Assessment (ESA) indicate that localized soil and/or ground water contamination by Page 2 of 3 3 Puget Sound Energy Grady Way Complex Remediation Project Project Narrative hazardous substances with concentrations exceeding applicable cleanup levels is present at eight locations in the southern portion of the site (see site plan sites B-7, B-19, B-23, B-29, B-34, TP-5, GMW-2, GMW-4). Contaminates detected at concentrations exceeding applicable cleanup levels during the ESA are as follows: • Total diesel- and heavy oil-range hydrocarbons were detected at a concentration slightly exceeding the MTCA Method A cleanup level in ground water obtained from GMW-2. • PCBs were detected at a concentration exceeding the MTCA Method A cleanup level in groundwater obtained from GMW-4. • PCBs were detected at concentrations exceeding the MTCA Method A cleanup level in soil obtained from B-7 (0.5 feet beneath the ground surface (bgs)), B-34 (0.5 feet bgs), and TP-5 (4.0 feet bgs). • Carcinogenic polynuclear aromatic hydrocarbons (cPAHs) were detected at concentrations exceeding the MTCA Method A cleanup level in soil obtained from approximately 0.5 feet bgs at the B-19, B-23, and B-29 locations. In addition to the contamination described above, cPAHs were detected at concentrations exceeding the MTCA Method A soil cleanup level in two of the six sediment samples obtained from catch basins in the southern portion of the site. The results of the ESA also indicate that residual PCB and/or cPAH concentrations exceeding applicable cleanup levels may be present in soil immediately adjacent to damaged portions of the stormwater drain lines. Diesel- and heavy oil-range hydrocarbons related to transformer oil and/or hydraulic/lube oil were detected in most of the near surface soil samples obtained for chemical analysis during ESA. However, the total petroleum hydrocarbon concentrations (23.4 to 2,120 milligrams per kilogram (mg/kg)) detected were less than the site specific MTCA Method B cleanup levels (3,432 for hydraulic/lube oil and 3,965 mg/kg for transformer oil) calculated using the Washington State Department of Ecology's Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy). Therefore, based on these calculations, additional cleanup activities will not be required in respect to these constituents. Page 3 of 3 CONSTRUCTION MITIGATION DESCRIPTION Proposed Construction Dates Puget Sound Energy proposes to perform the remediation and tank removal activities within 30 days following the submittal of the tank removal permits. Those permits will be submitted within approximately two weeks of a Determination of Non-Significance for this project. The project will occur over approximately a one-month period. Hours Of Operation Except for unusual circumstances, construction activities will typically occur on weekdays between 7:00 a.m. and 4:30 p.m. Proposed Hauling/Transportation Routes Remedial soils being removed will be taken to one of the following disposal sites: • Waste Management's Columbia Ridge Facility in South Seattle • TPS Technologies' Facility in Tacoma • Regional Disposal Company's Facility in South Seattle The same transportation route may access each of the potential disposal companies. PSE intends to haul disposal material from the Grady Way Complex along Grady Way to the I-405 exit. The hauler will then take the material south on I-405 to I-5. I-5 will be used to access any of the three potential disposal companies. Measures To Be Implemented To Minimize Dust, Traffic, And Transportation Impacts, Mud, Noise, And Other Noxious Characteristics The type of emissions to the air that would result from the proposal during construction and when the project is completed consist of emissions to the air, include dust during construction and vehicle exhaust during occupancy (similar to existing conditions). It is not anticipated that any measures will be required to reduce or control emissions or other impacts to air. Vehicles will be decontaminated to remove dust and dirt before exiting the remediation area. Measures that could be implemented, if needed, include spraying exposed soils with water or use of other dust suppressants during dry, windy weather. Noise will be created on a short-term basis and generated by the use of various types of construction equipment, which may include cranes, excavators, welding devices, air compressors and various vehicles with backup warning horns. Vehicles entering and leaving the site during the course of the project will also generate traffic noise. An estimated 150 to 200 truckloads will be required to remove tanks and contaminated soils from the site and bring in backfill material. The project will comply with State noise regulations under WAC 173-60 and 173-62; and local noise regulations under Renton Municipal Code (RMC) Chapter 7 Section 8. Construction hours will be limited as described above to ensure that the project does not exceed the maximum permissible noise levels established for construction sites under WAC 173-66-0410 through 050. CtN 5-p�� �;►ll' U- �u� 0 .11153 Puget Sound Energy Grady Way Complex Remediation Project Construction Mitigation Description Except in unusual circumstances, construction activities will typically occur on weekdays between 7:00 a.m. and 4:30 p.m. Most, if not all, of the work is planned to take place during daylight hours. In the event the work takes place during the shorter late fall and winter days, the contractor may elect to bring in temporary lighting to illuminate the tanks and the work space. Thus, during the tank removal, the potential source of light and glare is temporary workspace lighting. Following the tank removal, any temporary lighting will be removed and there will be no ongoing light or glare impacts. Parking lot and truck maneuvering areas will be illuminated during hours of darkness, similar to existing conditions. If cutting torches are used, the torch operators will wear appropriate protective clothing including welding hoods. Since the light intensity drops rapidly with distance from the source, the cutting torches would not create harmful glare at the property line. Measures To Be Implemented To Control Erosion Impacts No erosion is expected to occur as a result of the tank removal and soil remediation process. Any source of runoff would be from precipitation falling on the site. The proposed project will not change existing drainage patterns. The project is scheduled for the dry season, and because the site is relatively flat, we do not anticipate sedimentation or erosion problems during the project. The southern portion of the site is unpaved, and most of the precipitation will infiltrate into the ground. In the event that significant rain occurs, the silt fences installed downgrade of the project work area should mitigate any impacts. A temporary erosion and sedimentation control plan to control runoff will be included as part of the project specifications. The temporary erosion and sedimentation control plan will provide for the use of silt fencing, haybales or other measures to reduce runoff impacts from the remediation area. Vehicles will be decontaminated to remove dust and dirt before exiting the remediation area. Equipment and debris laydown areas will be designed to reduce potential runoff impacts. Mitigation measures may include the use of plastic sheeting as a liner below equipment and debris, covering equipment and debris with plastic sheeting as needed, and using berms, silt fencing or haybales as needed. Measures To Be Implemented Throughout Construction/Remediation Activities To Aesthetically Screen The Site Currently on the site the soil remediation area is fenced in. There are no proposed structure(s)to be constructed on this site as part of this proposal. No views in the immediate vicinity of the project will be altered or obstructed during the time of construction or after project completion. Since this project will be completed in the short span of one month, and no views will be obstructed or adverse aesthetic impacts will result from this project, no proposed measures to reduce or control aesthetic impacts are proposed: Page 2 of 2 UWGIN ENVIRONMENTAL CHECKLIST A.

Give a brief, complete description of your proposal, including the proposed uses and the size of the project and site. The Grady Way property is approximately twenty acres and is currently used and zoned as industrial property. The proposed project name is Grady Way Complex Remediation Project. PSE proposes to remove two existing underground fuel tanks, 10,000 gallons each (shown on the Site Plan). The tanks were installed new in October 1989 to current Washington State Underground Storage Tank (UST) Regulation. They are in good condition without any evidence of structural problems or leaks. The USTs are being used for the storage of gasoline and diesel used to fuel company vehicles. These two USTs are constructed of double wall fiberglass with automatic leak monitoring. (See attached plan for location) In addition to the two USTs mentioned above,the heating oil UST for the westerly building on this site will be removed. This UST contains diesel fuel for the building heating boiler. PSE will remediate any contamination caused by this UST to applicable Model Toxics Control Act (MTCA) standards. (See attached plan for location) A qualified UST removal contractor, licensed and experienced in the removal of USTs, will remove the three fuel USTs. The contractor, in accordance with PSE's removal specifications, will perform the necessary removal and restoration activities, including any associated remediation. All appropriate City, State, and Federal regulations pertaining to the removal of USTs will be adhered to in addition to other applicable requirements. The contractor will be required to provide UST removal and health and safety plans to specifically address tasks necessary to comply with applicable regulations and ordinances. A work plan will also be required of the contractor and will be available for review at the site at all times while project activities are underway. In addition to UST removal activities, there are multiple "hot spots" on the site where soil removal needs to occur. The total estimated volume of soil removal is approximately 2,030 cubic yards, with an estimated 1,000 cubic yards to be transported off site for disposal. Several catch basins and portions of the surface drainage system located in the southern portion of the site will also be removed and replaced Page 2 of 17 Puget Sound Energy Grady Way Complex Remediation Project Environmental Checklist (see attached plan for location). The following, from a report by GeoEngineers, provides details on the remaining contamination on the site: The results of the recently completed Environmental Site Assessment (ESA) indicate that localized soil and/or ground water contamination by hazardous substances with concentrations exceeding applicable cleanup levels is present at eight locations in the southern portion of the site (see site plan sites B-7, B- 19, B-23, B-29, B-34, TP-5, GMW-2, GMW-4). Contaminates detected at concentrations exceeding applicable cleanup levels during the ESA are as follows: • Total diesel-and heavy oil-range hydrocarbons were detected at a concentration slightly exceeding the MTCA Method A cleanup level in ground water obtained from GMW-2. • PCBs were detected at a concentration exceeding the MTCA Method A cleanup level in groundwater obtained from GMW-4. • PCBs were detected at concentrations exceeding the MTCA Method A cleanup level in soil obtained from B-7 (0.5 feet beneath the ground surface (bgs)), B-34 (0.5 feet bgs), and TP-5 (4.0 feet bgs). • Carcinogenic polynuclear aromatic hydrocarbons (cPAHs) were detected at concentrations exceeding the MTCA Method A cleanup level in soil obtained from approximately 0.5 feet bgs at the B-19,B-23,and B-29 locations. In addition to the contamination described above, cPAHs were detected at concentrations exceeding the MTCA Method A soil cleanup level in two of the six sediment samples obtained from catch basins in the southern portion of the site. The results of the ESA also indicate that residual PCB and/or cPAH concentrations exceeding applicable cleanup levels may be present in soil immediately adjacent to damaged portions of the stormwater drain lines. Diesel- and heavy oil-range hydrocarbons related to transformer oil and/or hydraulic/lube oil were detected in most of the near surface soil samples obtained for chemical analysis during ESA. However, the total petroleum hydrocarbon concentrations (23.4 to 2,120 milligrams per kilogram (mg/kg)) detected were less than the site specific MTCA Method B cleanup levels (3,432 for hydraulic/lube oil and 3,965 mg/kg for transformer oil) calculated using the Washington State Department of Ecology's Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy). Therefore, based on these calculations, additional cleanup activities will not be required in respect to these constituents. Puget Sound Energy intends to sell the Grady Way Complex site this year. Several potential purchasers have been identified. The remedial action is intended to prepare the site for sale. 12. Location of the proposal.

Our Phase I ESA research indicated that the first recorded site use was a coal mining operation in the late 1800s. PSE purchased the site around 1903. PSE's site uses have included transformer storage and maintenance, vehicle fueling and maintenance and storage of power poles treated with preservative. The site currently contains three buildings, three USTs, a storm water drainage system and various electrical equipment and materials stored and used by PSE. GeoEngineers monitored remedial activities at the site between 1987 and 1990. The remedial activities primarily focussed on the northern half of the property. Approximately 3,750 cubic yards of soil containing residual concentrations of petroleum hydrocarbons associated with former underground storage tanks (USTs) and hydraulic hoists were successfully removed from the site. Remaining petroleum hydrocarbon concentrations detected at the final limits of the hoist and UST remedial excavations were less than applicable cleanup levels. The results of this Phase I ESA indicated that there is a potential for petroleum hydrocarbons, polychlorinated biphenyls (PCBs) and semi-volatile organic compounds (SVOCs) including polynuclear aromatic hydrocarbons (PAHs), at concentrations of regulatory significance in soil and ground water in the southern half of the subject site. Between December 1997 and February 1998, GeoEngineers performed a Phase II ESA consisting of soil, sediment and ground water sampling and analysis to further evaluate the potential presence of hazardous substances. The Phase II ESA included 38 direct-push soil borings, nine shallow hand auger borings, five test pits, seven monitoring wells (six on-site and one off-site), 10 concrete samples, eight sediment samples and two coal mine tailings samples. In general, our Phase II assessment indicates that soil and ground water contamination of regulatory significance appears to be limited to portions of the southern third of the site. Additionally, our studies indicate that the potential for existing soil and/or ground water contamination of regulatory significance in the northern portion of the site is low. A summary of the Phase II ESA analytical results is presented below: • Diesel- and heavy oil-range hydrocarbons either were not detected or were detected at concentrations less than the Model Toxics Control Act (MTCA) Method A cleanup level [1 milligram per liter (mg/l)] in ground water samples obtained from the monitoring wells on-site with the exception of GMW-2 (1.37 mg/1 total petroleum hydrocarbons). • Diesel- and heavy oil-range hydrocarbons in soil samples either were not detected or were detected at concentrations [23.4 to 2,120 milligrams per kilogram (mg/kg)] less than the most conservative MTCA Method B cleanup level 3,432 (mg/kg) calculated for GeoEngineers 1 File No. 0186-407-00-1150/042998 this study using Ecology's Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy). • PCBs were detected at concentrations (1.33 to 1.85 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) at three locations in the southern portion of the site. • PCBs were detected at a concentration [1.17 micrograms per liter (AO)] exceeding the MTCA Method A cleanup level (0.1 µg/l) in ground water obtained from GMW-4 in the southern portion of the site. • Carcinogenic PAHs (cPAHs) were detected at concentrations (1.70 to 2.46 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) at three locations in the southern portion of the site. • cPAHs were detected at concentrations (2.87 to 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) in two of the six sediment samples obtained from catch basins in the southern portion of the site. The extent of residual cPAH and/or PCB concentrations exceeding applicable cleanup levels in the vicinity of B-7, B-19, B-23, B-29, B-34 and TP-5 were not fully evaluated by our study. However, based on our experience with these compounds at other similar PSE sites and the soil and ground water analytical results, we expect that the areas of contaminant concentrations exceeding cleanup levels are localized. Our conceptual volume estimate of soil containing PCB and cPAH concentrations exceeding MTCA Method A cleanup levels in the southern portion of the site is 500 cubic yards. The actual volume may vary significantly from this conceptual estimate. Based on the Phase I/II ESA results, it is our opinion that the potential for existing soil and ground water contamination by hazardous substances of regulatory significance on the subject site is low with the exception of the areas noted above. Chemical analysis did not detect contaminant concentrations exceeding applicable cleanup levels in 73 of the 81 soil/sediment samples and four of the six on-site ground water monitoring well samples submitted for chemical analysis. Significant concentrations of diesel- and heavy oil-range petroleum hydrocarbons were detected in soil and ground water obtained from monitoring well/boring GMW-7, located in Talbot Road, immediately downgradient from the southern portion of the site. In our opinion the source for the petroleum-related soil and ground water contamination detected in GMW-7 is not likely located on the subject site because petroleum-related contamination of regulatory significance was not detected in the two on-site wells (GMW-5 and GMW-6) located closest to, and upgradient of, GMW-7. Our study did not identify evidence concerning the specific source of the petroleum hydrocarbons detected in GMW-7. G e o E n g i n e e r s 2 File No. 0186-407-00-1150/042998 ENVIRONMENTAL SITE ASSESSMENT GRADY WAY COMPLEX PROPERTY RENTON, WASHINGTON FOR PUGET SOUND ENERGY 1.0 INTRODUCTION This report summarizes the results of our environmental site assessment (ESA) of Puget Sound Energy's (PSE) Grady Way Complex property located at 620 South Grady Way in Renton, Washington. This property is referred to herein as "the site." The site is shown relative to surrounding physical features in the Vicinity Map, Figure 1. The general layout of the site is shown in Figure 2. We understand that PSE is planning to sell the site. We further understand that the results of the ESA will be used to (1) evaluate environmental liabilities associated with site ownership and (2) identify remedial options to prepare the site for sale. GeoEngineers completed previous site characterization and remedial activities at the site as discussed in Sections 4.0 and 8.3 of this report. The previous studies primarily focussed on conditions in the northern half of the property. Chemical analytical results indicate that the remedial activities were successful in removing soil and ground water contamination of regulatory significance in the northern half of the site. The ESA described herein evaluated environmental conditions on the entire site; however, the Phase II portion of this study focussed on the southern half of the property. 2.0 SCOPE OF SERVICES The purpose of the ESA is to evaluate the presence or likely presence of hazardous substances, including petroleum products that may have resulted from current or past activities on the site or in the site vicinity. GeoEngineers' ESA services were completed in two phases. Phase I consisted of site reconnaissance, regulatory list evaluation and historical research completed in general accordance with American Society for Testing Materials (ASTM) Standard E1527-97 for Phase I ESAs. Phase II consisted of concrete, soil, sediment and ground water sampling and chemical analysis. Our specific scope of services completed for this ESA follows. 2.1 PHASE I • Review readily available environmental/geotechnical reports, and/or other relevant documents pertaining to environmental conditions at the site. • Review federal, state, and local environmental database search results provided by Environmental Data Resources (EDR) for listings of known or suspected environmental GeoEngineers 3 File No. 0186-407-00-1150/042998 problems at the site or nearby properties. The specific databases and minimum search distances reviewed included the following: U.S. Environmental Protection Agency Lists Minimum Search Distance National Priorities List (NPL) 1 mile Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS) 0.5 mile Resource Conservation and Recovery Act (RCRA), Corrective Action Report (CORRACTS) Facilities List 1 mile RCRA non-CORRACTS TSD Facilities List 0.5 mile RCRA Notifiers List, Generators and Transporters Site and Adjoining Properties Emergency Response Notification System (ERNS) Site State and Local Health Department Lists Minimum Search Distance Washington State Department of Ecology (Ecology) Department Lists Toxics Cleanup Program Confirmed and Suspected Contaminated Sites List (C&SCS) 0.5 miles Model Toxics Control Act (MTCA) Site Register 1 mile Ecology Registered Underground Storage Tank (UST) Sites List Site and Adjoining Property Ecology Leaking UST (LUST) Sites List 0.5 mile Solid Waste Disposal Facility 0.5 mile • Review regulatory agency files regarding listed sites of potential environmental concern relative to the site. • Identify key persons with specific knowledge of past and present site use and request that they meet a GeoEngineers' representative on-site for an interview during the site reconnaissance. Interview others familiar with past and present uses of the site and its vicinity as necessary. • Interview a representative of the local fire department, health department, and/or Ecology regarding the history of the site and surrounding properties relative to the likely presence of hazardous substances. • Review historical aerial photographs, fire insurance maps, city directories, tax assessor records, other historical maps and building department records, as available and appropriate, to identify past development history on the subject site and adjacent properties relative to the possible use, generation, storage, release or disposal of hazardous substances. We attempted to identify uses of the site from the present to the time that records show no apparent development of the site. However, we did not obtain historical information regarding on site activities prior to the late 1800's, at which time coal mining activities were being conducted on a portion of the site. GeoEngineers 4 File No. 0186-407-00-1150/042998 • Review current United States Geological Survey (USGS) topographic maps to identify the physiographic setting of the site. • Identify the sources of potable water for the site; the type of heating systems for site structures; and the type of sewage disposal at the site. • Provide a statement on the local geologic, soil and ground water conditions based on our general experience and sources such as geologic maps and soil surveys. • Conduct a visual reconnaissance of the site and adjacent properties to identify any visible evidence of possible contamination and potential sources of contamination. 2.2 PHASE II 1. Obtain 10 concrete surface samples (C-1, C-2 and C-4 through C-11) from selected transformer storage areas at the site. A concrete sample designated as C-3 was not obtained during the study. 2. Submit the concrete samples for chemical analysis of polychlorinated biphenyls (PCBs) by U.S. Environmental Protection Agency (EPA) Method 8081. 3. Obtain soil samples from 38 shallow direct-push borings (B-1 through B-38), nine shallow hand auger borings (B-39 through B-47), five test pit excavations (FP-1 through TP-5) and seven monitoring well borings (GMW-1 through GMW-7) at approximately 1- to 2-foot depth intervals. The explorations were completed to depths of approximately 3.0 to 12.0 feet beneath the ground surface. GMW-7 was completed off-site in Talbot Road, immediately downgradient of the southern portion of the property. 4. Obtain two sediment samples (S-1 and S-2) from a small storm water pond located in the eastern portion of the site; six sediment samples (S-3 through S-8) from inside selected stormwater catch basins on site; and two composite samples (GC-1 and GC-2) of coal mine tailings stockpiled in the eastern portion of the site. 5. Field screen the soil samples for possible petroleum hydrocarbon contamination. 6. Construct 2-inch-diameter monitoring wells in GMW-1 through GMW-7. 7. Survey the well casing elevations relative to an assumed site datum and measure the depth to ground water in each monitoring well on-site. 8. Obtain ground water samples from an existing monitoring well (MW-10), eight direct-push borings (B-30 and B-37) and GMW-1 through GMW-7. 9. Submit selected concrete, soil, sediment, coal mine tailings and ground water samples for one or more of the following chemical analyses: a. Diesel- and heavy oil-range hydrocarbons by Washington State Department of Ecology (Ecology) Method NWTPH-D extended. Samples B-1-3.0, B-32-0.5 and GMW-4-6.0 also were analyzed for volatile petroleum hydrocarbon (VPH) fractions; benzene, ethylbenzene, toluene and xylenes (BETX) and/or extractable petroleum hydrocarbon (EPH) fractions by Ecology's Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy) methods.

Semivolatile organic compound (SVOCs) by EPA Method 8270 10. Calculate site-specific Mode! Toxics Control Act (MTCA) Method B cleanup levels for petroleum hydrocarbons detected in the soil samples using Interim TPH Policy methods. 11. Evaluate the analytical results relative to current environmental regulations. Our scope of services did not include an environmental compliance audit, asbestos survey, lead-based paint survey, an evaluation of the potential presence of PCBs in light ballasts, or urea-formaldehyde insulation in on-site structures. Prezant Associates completed an inventory of asbestos, lead-base paint, and PCB in light ballasts in the on-site Stores and Service Center buildings. The results of the Prezant Associates studies are presented in written reports dated July and August 1995. The Prezant Associates reports were provided to GeoEngineers and are on file at PSE's Seattle office. 3.0 INVOLVED PARTIES The site currently is owned and operated by PSE. We understand that PSE is planning to sell the site through its wholly owned subsidiary, Puget Western Inc. 4.0 PREVIOUS ENVIRONMENTAL/GEOTECHNICAL INVESTIGATIONS GeoEngineers has provided environmental consulting services related to the subject site since 1987. Written reports summarizing the results of our previous site studies are on file with Ecology and include the following: • "Final Report - Ground Water Quality Testing, Underground Transformer Oil Tank, Service Center, Renton, Washington" -January 15, 1988. • "Final Report - Tank Removal and Soil Excavation, Underground Transformer Oil, Tank Service Center, Renton, Washington" - March 3, 1988. • "Report of Geotechnical Services, Subsurface Contamination Study, Former Renton Transportation Center, Renton, Washington" - July 26, 1988. • "Report of Remedial Action, Underground Storage Tank Removal, Renton Service Center, Renton, Washington" - December 15, 1989. • "Supplemental Report - GeoEnvironmental Services, Off-site Subsurface Contamination Study, General Stores Building, Renton Service Center, Renton, Washington" - November 29, 1990. • "Supplemental Report - GeoEnvironmental Services, Subsurface Contamination Study and Ground Water Monitoring Program, General Stores Building, Renton Service Center, Renton, Washington" - December 18, 1990. • "Report of Geotechnical Services, UST Removal and Subsurface Contamination Study, Stores Building, Renton Service Center, Renton, Washington" -January 17, 1990. GeoEngineers 6 File No. 0186-407-00-1150/042998 • "Report of Remedial Action, Underground Storage Tank Removal, Stores Building, Renton Service Center, Renton, Washington" - February 7, 1991. • "Report of Remedial Action and Geotechnical Services, Hydraulic Fluid Remedial Program, Stores, Building, Renton Service Center, Renton, Washington" - October 4, 1991. In addition to the studies described above, GeoEngineers conducted research in 1995 to evaluate historical site use. The results of that research are on file at PSE and were used to supplement the site history research (Section 8.0) for the Phase I portion of this study. 5.0 ENVIRONMENTAL SETTING Our knowledge of the general physiographic setting, geology, and ground water occurrence in the site vicinity is based on our review of the United States Geological Survey (USGS) Renton Quadrangle Topographical Map, dated 1949 (photo revised 1973); the EDR report; USGS Geologic Quadrangle Map of the Renton Quadrangle, King County, Washington, dated 1965; the results of our previous site studies and our general experience in the area. 5.1 REGIONAL PHYSIOGRAPHIC CONDITIONS The site is located in the northeast quarter of Section 19, the southwest quarter of Section 17 and the northwest quarter of Section 20, all lying within Township 23 North, Range 5 Rao, Willamette Meridian. The surface elevation of the site is approximately 40 feet above mean sea level. The subject site is located approximately 1/2 mile south of Cedar River and approximately 2 miles south of Lake Washington. 5.2 SOIL AND GEOLOGIC CONDITIONS The site vicinity is underlain by widespread or discontinuous artificial fill according to the geologic map we reviewed. Subsurface exploration performed by GeoEngineers at the site during previous studies encountered fill generally consisting of gravel, silty sand, silt and/or coal mine tailings to depths of up to 14 feet beneath the site surface. Native sand and silt units underlie the fill. 5.3 GROUND WATER CONDITIONS GeoEngineers constructed 33 monitoring wells in and around the northern portion of the Stores building during our previous studies. The locations of the monitoring wells previously installed at the site are shown in our previous reports. Additionally, GeoEngineers constructed four monitoring wells in the vicinity of a former transformer oil UST located south of the Stores building. Ground water generally was encountered at depths of approximately 5 to 8 feet beneath the site surface in these areas. The general direction of shallow ground water flow beneath the site is toward the west based on water level measurements. Most of the wells completed during our previous studies were removed during subsequent remedial excavation GeoEngineers 7 File No. 0186r407-00-I150/042998 activities or abandoned in place. However, monitoring wells MW-4, MW-8, MW-10 and MW-20, located near the north/northwest corner of the Stores building, remain intact. 6.0 GENERAL SITE CHARACTERISTICS 6.1 LOCATION AND LEGAL DESCRIPTION The site is located at 620 South Grady Way in Renton, Washington. The legal description of the site is presented in Appendix A. 6.2 SITE RECONNAISSANCE OBSERVATIONS Representatives of GeoEngineers performed a visual reconnaissance of the site on October 7, 1997. Subsequent site reconnaissance was conducted on December 17, 18 and 22, 1997 and February 18, 19, 20, 23 and 26, 1998 during Phase II tasks associated with this study. Primary site access is from South Grady Way. The approximate locations of the features discussed in this section are shown in Figure 2. Photographs of the site were taken to document observations made during our reconnaissance on October 7, 1997. Selected photographs of the site are presented in Figures 3a and 3b. Site features of potential environmental significance are discussed below. 6.2.1 Site Improvements The site consists of approximately 20.5 acres and is occupied by three buildings: the Stores building, the Service Center building, and the Division Office building. The Stores building serves as a warehouse and transformer storage and repair shop. The Service Center building is used as office space and for equipment/supply storage. The Division Office building is no longer occupied. It is currently used to store office furniture and equipment. Yard and dock areas south, west and east of the buildings currently are being used for transformer storage. A loading bay area located immediately west of the Service Center building currently is used to store PCB containing transformers that have leaked. The leaking transformers are stored in secure basins designed to contain their oil. A portion of the transformer storage yard previously was used to store power poles treated with preservative. A security fence surrounds the area in which the Stores building, Service Center building and transformer/former pole storage yard, and associated parking are located. A fuel service island and two registered 10,000 gallon fuel (gasoline and diesel) USTs, installed in 1989, are located between the Service Center building and the Stores building. A 2,000 gallon heating oil UST is located immediately east of the Stores building. Eight other fuel and oil USTs were removed from the site between 1987 and 1990 as described in our March 3, 1988, December 15, 1989, January 17, 1990 and February 7, 1991 reports. The majority of the area within the fence is paved with asphaltic concrete. The southern portions of the transformer/former pole storage yard are surfaced with gravel. The site areas south and east of the security fence are undeveloped. _ G e o Engineers 8 File No. 0186-407-00-1150/042998 6.2.2 Pits, Ponds and Lagoons No pits or lagoons were observed on the site. A "marshy area" is located south of the site's security fence. Additionally, a small storm water pond is located in the eastern portion of the property (Figure 2). The pond appears to catch surface water runoff at the base of a hill that slopes up to the adjacent Benson Road South. We did not observe sheens or other physical evidence of contamination by hazardous substances at the pond location. 6.2.3 Site Drainage Surface drainage primarily is directed toward numerous catch basins on the site. Additionally, water from the previously mentioned pond flows into a drainage ditch (concrete-lined) located adjacent to the fence in the southern portion of the site. Water from the drainage ditch and the catch basins flows into the local storm water system at the southern portion of the site. A utility map, including the general layout of the site's storm water drainage system, is shown in Figure 4. 6.2.4 Stressed Vegetation, Stained Soil or Pavement Stressed vegetation, attributed to hazardous substances, was not observed on-site. A dark stain was observed on the concrete surface of the loading bay immediately west of the Service Center building. The cause of the stain is unknown. Other dark stains were observed on the pavement surface in areas where vehicles have been parked. These stains generally are less than 3 feet in diameter and, in our opinion, appear to have been caused by periodic low volume dripping of oil or grease from parked cars. Other significant stains were not observed on the site surface. 6.2.5 Water Wells, Sumps and Drains We observed four monitoring well monuments (MW-4, MW-8, MW-10 and MW-20) which were installed during previous GeoEngineers studies of the Stores building and its vicinity. Additionally, six new monitoring wells (GMW-1 through GMW-6) were constructed on-site during the Phase II portion of this study (Section 9.4). The Stores building contains a sump for condensation water located in the northwest corner of the heating system's boiler room. An "oil water separator", an "oil interceptor" and two "oil trap vaults" also were observed on-site (Figure 2). Additionally, the site contains numerous catch basins for surface water drainage as described in Section 6.2.3. Other evidence of water wells, sumps or drains was not observed on site. 6.2.6 Areas of Standing Water or other Liquids Areas of standing water or other liquids were not observed on the site with the exception of the small storm water pond described in Section 6.2.2. GeoEngineers 9 Filo No. 0 1 86-40 7-00-1 1 50/04299 8 6.2.7 Waste Generation and Disposal Unconfined refuse and/or debris was not observed on the site. PSE representatives we interviewed indicated that PCBs are removed from waste water stored in an AST (Section 6.2.8) located on the Service Center building loading dock and that the treated water is subsequently discharged into the metro sewer system in accordance with a discharge permit. Stockpiles of coal mine tailings are present between Main Avenue South/Benson Road South and the fence that borders the eastern portion of the storage yard. These stockpiles generally are densely vegetated with blackberry bushes. 6.2.8 Storage Tanks and Containers Three USTs are located on site: one 10,000-gallon diesel fuel UST and one 10,000-gallon unleaded gasoline UST, installed in 1989, and one 2,000-gallon heating oil UST. The USTs are located between the Stores building and the Service Center building near the north end of the fenced area. Two storage tanks containing up to 119 gallons of propane were observed on the site. Additionally, we observed the 3,700-gallon AST that contains waste water located in the Service Center loading dock. One storage shed ("RCRA shed"), used to contain batteries, was observed south of the Stores building. We observed 11 containers used to store leaking PCB-containing transformers located in the Service Center Bay area. We also observed approximately one hundred and fifty 55-gallon drums on site during our October 7, 1998 reconnaissance. The approximate drum storage locations observed on October 7, 1997 are shown in Figure 2. Labels on the drums identified the contents as waste soil, oil and other liquids. PCB-containing materials were present in some of the drums. Other drums observed on-site were labeled "non-hazardous." Based on our observations during subsequent site visits and our interviews with PSE representatives, it is apparent that the content and number of drums stored on the site changes regularly. The drums we observed appeared to be in good condition. We did not observe evidence of leakage from the drums. 6.2.9 Indications of PCBs, Transformers and Utilities The Stores building is utilized, in part, as a transformer repair shop. Some of the transformers contain PCBs. PCB transformers, identified as having leaked, currently are stored in 55-gallon drums which are stored in large plastic containers in the area designated for storage of leaking transformers; this storage area is located west of the Service Center building. PCB-containing materials and PCB storage areas at the site are managed in accordance with federal Toxic Substances Control Act (TSCA) regulations and PSEs PCB-handling program. Numerous non-PCB containing transformers also are stored on the site. The site contains one operating transformer in a vault located immediately east of the Service Center building. The transformer vault was secured in such a manner that access was G e o E n g i n e e r s 10 File No. 0186-407-00-1150/042998 not practical during our site reconnaissance. PSE representatives we spoke with indicated that they are unaware of any releases of insulating oil from the transformer in the vault. The City of Renton supplies the site with water and sewage service. The Stores building is heated with a boiler fueled by heating oil. The Service Center building and the vacated Division office building are heated by electricity. 6.2.10 Radon We contacted the Washington State Department of Health (DOH) regarding the potential for radon gas in Western Washington. According to DOH, the potential for radon gas in the Puget Sound region is very low. It is estimated to that only one percent of houses in the Puget Sound region have radon gas concentrations exceeding 4 picocuries per liter (pCi/L). The national average for radon gas concentrations in buildings and structures is 4 pCi/L. According to DOH, radon gas is typically not a problem in larger buildings that have forced air or better ventilation. We also contacted the EPA Radiation Protection Program. EPA representatives concur with the opinion of DOH regarding the radon gas potential in the Puget Sound Region. Additionally, EPA suggested that radon gas concentrations in the Puget Sound region are low for the following reasons: (1) a low uranium content in soils (radon gas is a decay product of uranium 238), (2) moist soil conditions (moisture inhibits radon movement), and (3) a high degree of fines in the soil (lower permeability soils inhibit radon gas movement). Based on our conversations with personnel from the EPA and DOH, it is our opinion that the potential for radon gas at concentrations in excess of 4 pCi/L at the site is low. 6.2.11 Other Conditions of Concern We did not observe other conditions of concern regarding the potential for site soil and/or ground water contamination by hazardous substances. 6.3 ADJACENT PROPERTY AND VICINITY OBSERVATIONS Residential, commercial and undeveloped properties border the subject site to the north. A parking structure is located immediately northeast of the site. The eastern and southern portions of the site are bordered by Main Avenue South and Benson Road South, respectively. Interstate Highway 405 is on the opposite side of Main Avenue South. The adjacent properties to the south and west are occupied by commercial and office buildings that are separated from the site by Benson Road South and Talbot Road South, respectively. An AM/PM ARCO service station is located immediately west of the site, at the intersection between Talbot Road South and South Grady Way. We did not observe any evidence of past or present use, storage, generation, release, or disposal of hazardous substances on adjacent properties with the exception of fuel storage at the nearby serviee station, located downgradient (west) of the site. G e o E n g i n e e r s 11 File No. 0186-407-00-1150/042998 7.0 ENVIRONMENTAL RECORDS REVIEW GeoEngineers reviewed the results of an environmental records (regulatory lists) search for those facilities that currently or previously have occupied properties within an ASTM-specified distance from the subject site. The information reviewed was compiled by EDR. The EDR report is included in Appendix B. The report includes details regarding the listed facilities identified and maps showing the locations of the listed facilities relative to the subject site. The subject site is included on the registered UST and the leaking UST lists according to the EDR report we reviewed. The UST site number for the Grady Way Complex is 8532. The site is listed for the current and former USTs described in Sections 6.2.8 and 8.3 of this report. The site is included on the leaking UST list because of soil conditions encountered around the site's former USTs (now removed). These areas were successfully remediated between 1987 and 1990 as documented in our prior reports. Those listed off-site facilities found within the specified distance from the subject site were evaluated for potential impact to the subject site. The listed facilities identified either are located a significant distance (1/4 mile or greater) from the site or are located in an inferred down- or cross-gradient location relative to the site, based on our review. In our opinion, the potential for subject site contamination originating from one or more of the listed facilities identified in the EDR report is low. Therefore, we did not review Ecology files for the listed facilities with the exception of the file for the service station located immediately west (downgradient) of the site at 509 S. Grady Way. We reviewed the file for this service station because of its proximity to the subject site. Documents in the Ecology file do not indicate that contamination from the service station facility has impacted the subject site. Additionally, there were no indications that contaminants from the subject site have migrated onto the service station property. 8.0 SITE HISTORY Our understanding of site history is based on the results of our prior site studies; review of Sanborn fire insurance maps dated 1904, 1909, 1927 and 1929; evaluation of aerial photographs dated 1936, 1946, 1960, 1968, 1974, 1977, 1980, 1985 and 1992; review of various PSE file materials including maps, building plans, spill reports and a spill prevention control and counter measure plan; and interviews with the following persons: • Larry Herwitz of PSE (08/14/95) • Manny Wilson of PSE (08/17/95) • Bob Banasky of PSE (08/17/95) • Lance Taylor PSE (08/17/95 and 11/19/97) • Renato Pagalilauan of PSE (08/17/95) • Kevin Case of PSE (08/17/95) • Kate Oehler of PSE (08/17/95) G e o Engineers 12 File No. 0 1 86-407-00-1 1 50/042998 • Bill Carey of PSE (08/17/95) • Jerry McNeilly of PSE (08/17/95) • Curtis Dahlgren of Ecology (08/25/95) • Dave Yasuda of PSE (10/02/97) • Reid O. Kinne of PSE (10/07/97) • Julie, Renton Fire Department (11/04/97) • Brenda Campbell of PSE (11/12/97) • Patty McClements of PSE (11/17/97) • Allan Miller of PSE (2/20/98) A summary of historical site use based on these sources is presented below. 8.1 GENERAL • PSE purchased most of the site and adjacent property west of the site, across Talbot Road South around 1903. A portion of the adjacent property west of the site was developed as an electrical substation in the early 1940s. • An entrance to a coal mine was located in the eastern portion of the site in the late 1800s and early 1900s. Large piles of coal mine tailings covered portions of the site at that time. A railroad spur was located in the eastern portion of the site. It appears that PSE owned a part or all of the coal mine operation, based on Sanborn maps and PSE's real estate files. Current site facilities were constructed on fill consisting of the coal mine tailings. The nature of the on-site fill is discussed in Section 9.2. • The site was used as a pasture for a farm after the coal mine stopped operation. • The Stores building was constructed in 1951 and the Service Center and Division Office buildings were constructed in 1956, according to tax records. The Division Office building is no longer in use. • PSE's current and past activities performed at the site include (1) warehousing a stock of supplies for other PSE facilities, (2) storage and maintenance of transformers, and (3) fueling and maintenance of fleet vehicles. • Some of the materials warehoused at the site include PCBs at concentrations greater than 500 parts per million (ppm). • Vehicle maintenance and repair took place in the northern (garage) portion of the Stores building until approximately 1991. Hydraulic lifts and USTs in that area were removed. • A vegetated "marshy" area is located south of the site security fence. • Some of the PSE personnel we interviewed speculated that transformers may be buried beneath portions of the southern half of the site. Our research did not identify other historical information suggesting that transformers were buried on-site. Test pits TP-1 through TP-5, monitoring well borings GMW-3 through GMW-6 and hand auger borings B-40 through B-47 (Figure 5), were completed during Phase II of this study in G e o E n g i nee r • 13 File No. 0 1 86-407-00-1 1 50/042998 areas identified as possible transformer burial locations based on our interviews. Transformers were not encountered in our subsurface explorations. • The fire department indicated that they have no records of historical hazardous materials "incidents" (spills or fires) at the subject site. We did not identify any historical adjacent property use that represents a significant potential source of contamination by hazardous substances on the subject site. 8.2 TRANSFORMER REPAIR SHOP AND TRANSFORMER/POLE STORAGE YARD • The transformer repair shop has been in use at the site for at least 25 years and is located in the southern portion of the Stores building. • Two fiberglass ASTs that contained acid and an unidentified "cleaner" were located in the transformer repair shop and were used to clean transformers. Transformers were submerged in the tanks to remove paint. The tanks were taken out of service around 1986. We obtained a ground water sample from boring B-32, located immediately adjacent to the transformer repair shop during Phase II of this study to evaluate the potential presence of solvents (HVOCs) near these former tanks. HVOCs of regulatory significance were not detected in the ground water sample obtained from B-32 (Section 9.4). • Transformers have been stored on the site for at least 35 years. PSE implemented a program approximately 12 years ago for documenting spills and subsequent cleanups that occur at the Grady Way site. Transformer storage primarily has occurred in the areas south and west of the Stores building and the area south and east of the Service Center. We understand that PCB-containing transformers have been stored and managed separately from non-PCB transformers for at least 12 years. • PCB-containing transformers currently are stored on the concrete storage docks adjacent to the transformer repair shop and the Service Center building. We understand that some of the PCB-containing transformers may have been stored in the transformer storage yard prior to 1980. • PSE's Spill Prevention Control and Countermeasure (SPCC) plan identified three areas of the site as current "PCB Storage Areas." These locations are shown in Figure 2. • A transformer oil AST was located on the storage dock at the southern end of the stores building. According to Lance Taylor, this AST was removed approximately three years ago. • Power poles treated with creosote were stored on the site in the area south of the Stores building until approximately 1990. We understand that the application of chemical preservatives to the poles did not take place at the site. G e o E n g i nee r s 14 File No. 0186-407-00-1150/042998 8.3 PREVIOUS REMEDIAL ACTIONS • GeoEngineers monitored the excavation and removal of approximately 650 cubic yards of petroleum-contaminated soil from the vicinity of a waste transformer (insulating/mineral) oil UST in 1987. The contaminated soil and the UST were transported off-site for permitted disposal. The waste transformer oil UST was located south of the transformer repair shop in the transformer storage yard. The UST was connected to a vault in the transformer repair shop by underground piping. The approximate extent of this remedial excavation is shown in Figure 2. • GeoEngineers consulted Ecology and established a remedial action level (RAL) for total petroleum hydrocarbons of 300 milligrams per kilogram (mg/kg) during remediation of soil contamination near the waste transformer oil UST to account for the effect of the coal tailings on TPH concentrations detected by chemical analysis. • GeoEngineers monitored the removal of seven additional USTs from the vicinity of the Service Center and Stores buildings in 1989 and 1990. The approximate locations of these former USTs and associated remedial excavations are shown in Figure 2. • Approximately 3,100 cubic yards of hydraulic fluid-contaminated soil were removed from the former garage area located in the northern portion of the Stores building in 1990. The hydraulic fluid-contaminated soil was transported to a permitted landfill for disposal. The garage, including three hydraulic lifts, was taken out of service in 1990. • The USTs removed in 1989 and 1990 were replaced with a 10,000-gallon gasoline UST, a 10,000-gallon diesel UST and a fuel island located east of the former garage area. We understand that the new USTs are double-walled and contain interstitial leak detection devices. There have been no reported leaks from the new USTs according to PSE and the Ecology records we reviewed. • Field screening and chemical analytical results for soil samples obtained from the final limits of the prior remedial excavations indicate that soil containing residual petroleum hydrocarbon concentrations exceeding applicable MTCA cleanup levels were successfully removed from the former UST and hydraulic lift areas. • A heating oil UST is located east of the Stores building. We understand that the original heating oil UST, installed in approximately 1950 at the site, was replaced with the current heating oil UST in the same location. We further understand that visual observations during the heating oil UST replacement indicated that minor amounts of petroleum-related soil contamination may exist in the vicinity of the UST. Chemical analysis of a ground water sample obtained from boring B-37, located immediately downgradient of the UST, did not detect petroleum hydrocarbons (Section 9.4). 8.4 ENVIRONMENTAL LIENS During the course of our research, we did not find that environmental liens had been filed against the site. - GeoEngineers 15 File No. 0186-407-00-1150/042998 9.0 PHASE II ENVIRONMENTAL SITE ASSESSMENT 9.1 CONCRETE SAMPLES AND ANALYSIS A representative of GeoEngineers obtained ten concrete samples (C-1, C-2 and C-4 through C-11) from various transformer storage locations at the site for PCB analysis on December 18 and 22, 1997. The concrete samples were obtained from the surface of the storage/loading docks where transformers have been stored. The approximate concrete sample locations are shown on Figure 5. PCBs were detected in samples C-2, C-4, C-5, C-7, C-8, C-9 and C-11 at concentrations ranging from 75.9 to 1,050 micrograms per kilogram Gig/kg). The concrete analytical results are presented in Table 1. Concrete sampling methods are described in Appendix C. Laboratory reports for the concrete samples are presented in Appendix D. 9.2 SOIL SAMPLING AND ANALYSIS Soil conditions in the eastern and southern portions of the site were evaluated by obtaining discrete soil samples from 38 shallow direct-push borings (B-1 through B-38), nine shallow hand auger borings (B-39 through B-47), five test pit excavations (TP-1 through TP-5), and seven monitoring well borings (GMW-1 through GMW-7). Additionally, two grab samples were obtained from the coal mine tailings stockpiles (GC-1 and GC-2) at approximately 1- to 2-foot depth intervals. The explorations were completed between December 18, 1997 and February 23, 1998 to depths of approximately 3.0 to 12.0 feet beneath the ground surface (bgs) at locations of suspected subsurface contamination based on the results of the Phase I ESA. GMW-7 was completed off-site in Talbot Road immediately downgradient of the southern portion of the property (ground water flow direction is discussed in Section 9.4). The approximate locations of the explorations completed for this study are shown in Figure 5. Field sampling methods and soil logs are presented in Appendix C. Geologic cross sections depicting the soil conditions encountered in our explorations are presented in Figures 6a and 6b. The soil samples were classified and field screened for evidence of potential petroleum hydrocarbon contamination. The explorations generally encountered loose to dense fill consisting of near surface sand or gravel underlain by coal mine tailings. The coal mine tailings consist of black silt and sand with varying amounts of coal fragments. The tailings consist primarily of coal fragments in some portions of the site. Deeper explorations generally encountered native silt or sand approximately 10 to 12 feet bgs. Field screening evidence of petroleum hydrocarbons was not detected in the soil samples obtained from.the explorations, with the exception of samples GMW-7-8.0 and GMW-7-11.0. Seventy-three soil samples were submitted to North Creek Analytical Laboratory of Bothell, Washington for one or more of the chemical analyses described in Section 2.2. Soil samples were selected for analysis based on their location relative to suspected sources of GeoEngineers 16 File No. 0 1 86-407-00-1 1 50/042998 contamination and/or the ground water table. Many of the soil samples obtained from depths of approximately 0.5 foot of the site surface were submitted for chemical analysis to evaluate the effects of surface spills from transformers and/or impacts from the wood preservative present on the power poles that were formerly stored on-site. Selected soil samples from approximately 2.0 to 3.0 feet bgs were submitted for analysis to evaluate the vertical extent of residual contamination detected in shallower samples. The chemical analytical results are described below. 9.2.1 Petroleum Hydrocarbons Diesel- and heavy oil-range petroleum hydrocarbons were detected in most of the soil samples submitted for chemical analysis. Our Phase I ESA research and chemical analyses indicate that periodic transformer (insulating/mineral) oil leaks from electrical transformers stored in the southern and eastern portions of site during the past 40 years have resulted in residual concentrations of petroleum hydrocarbons in soil. Transformer oil elutes in the diesel- and heavy oil-range when analyzed by gas chromatography. The residual transformer oil- related hydrocarbons in soil at the site were quantified either as transformer oil and/or undifferentiated diesel- and heavy oil-range hydrocarbons by the laboratory. Chemical analysis also detected hydraulic/lube oil-range hydrocarbons in some of the soil samples. A specific source of these hydraulic/lube oil-range hydrocarbons was not identified by our study. Site specific MTCA Method B cleanup levels were calculated using Ecology's Interim TPH Policy for the petroleum hydrocarbons detected. MTCA Method B cleanup level calculations are summarized in Appendix E. Petroleum hydrocarbon concentrations in all the soil samples submitted for analysis were less than the MTCA Method B cleanup levels calculated for the site. The MTCA Method B cleanup levels calculated for the specific hydrocarbon ranges identified were 3,965 mg/kg for transformer oil-related hydrocarbons quantified as diesel- and heavy oil-range hydrocarbons, 3,971 mg/kg for hydrocarbons specifically quantified as transformer oil, and 3,432 mg/kg for hydraulic/lube oil-range hydrocarbons. Petroleum hydrocarbon concentrations detected in soil on-site ranged from 23.4 to 2,120 mg/kg. Petroleum hydrocarbon concentrations in the soil samples tested generally decreased significantly within approximately 3 feet of the site surface. Chemical analysis detected diesel- and heavy oil-range hydrocarbons at concentrations of 3,890 mg/kg and 2,390 mg/kg respectively in the soil sample obtained from GMW-7 approximately 8.0 feet beneath Talbot Road immediately west of the site. Numerous utility trenches are located beneath Talbot road. Utility trenches can act as a conduit for migration of petroleum hydrocarbons relatively long distances from their source. The source of the petroleum hydrocarbons in GMW-7 was not identified by our study. Soil chemical analytical results for petroleum hydrocarbons at the site are presented in Table 2. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. - G e o En g i nee r s 17 F'le No. 0186-407-00-1150/042998 9.2.2 PCBs PCBs either were not detected or were detected at concentrations less than the MTCA Method A cleanup level (1 mg/kg) in the 53 soil samples submitted for PCB analysis with the exception of soil samples B-7 (1.33 mg/kg), B-34 (1.62 mg/kg) and TP-5 (1.85 mg/kg). These three samples were obtained from approximately 0.5, 0.5 and 4.0 bgs, respectively. Soil chemical analytical results for PCBs are presented in Table 3. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. 9.2.3 SVOCs SVOCs including pentachlorophenol (PCP) and carcinogenic polynuclear aromatic hydrocarbons (cPAHs) either were not detected or were detected at concentrations less than applicable MTCA cleanup levels (8.33 mg/kg PCP and 1 mg/kg cPAHs) with the exception of soil samples B-19 (1.70 mg/kg cPAHs), B-23 (2.46 mg/kg cPAHs) and B-29 (2.05 mg/kg cPAHs). These samples were obtained from a depth of approximately 0.5 foot bgs. Soil chemical analytical results for SVOCs are presented in Table 3. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. 9.3 SEDIMENT SAMPLES A representative of GeoEngineers obtained two sediment samples (S-1 and S-2) from the storm water pond and six discrete sediment samples (S-3 through S-8) from selected catch basins on February 18, 1998 at the approximate locations shown in Figure 5. Petroleum hydrocarbons and PCBs either were not detected in the sediment samples or were detected at concentrations less than MTCA soil cleanup levels. Sediment samples S-4 and S-5 contained cPAH concentrations (2.87 and 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) for cPAHs. Freshwater sediment cleanup levels have not been established under MTCA. Sediment chemical analytical results are presented in Tables 2 and 3. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. We estimate that the on-site catch basins contain less than two cubic yards (total) of sediment based on our observations. 9.4 GROUND WATER Ground water conditions beneath the site were explored by obtaining ground water samples from eight of the direct-push borings (B-30 through B-37) and seven monitoring wells (GMW-1 through GMW-7) installed during this phase of work. The approximate boring and well locations are shown in Figures 5 and 7. Well construction details and ground water monitoring methods are presented in Appendix C. GeoEngineers 18 File No. 0 1 86407-00-1 1 50/04299 8 Water levels were measured in existing wells MW-4, MW-8, MW-10 and MW-20 on December 22, 1997 and in new and existing wells MW-4, MW-8, MW-10, MW-20 and GMW-1 through GMW-7 on February 26, 1998. Water levels at the time of our measurements ranged from 1.87 (GMW-3) to 7.84 (MW-8) feet bgs. The ground water table beneath the site was slightly higher in December 1997 than in February 1998 based on our measurements. Ground water depth measurements and calculated ground water table elevations are presented in Table 4. A ground water contour map based on our February 26 measurements is presented in Figure 7. Shallow ground water appears to flow in a westerly direction beneath the site, based on our February 26 measurements. Ground water samples from selected borings (B-30 through B-37) and MW-10 were obtained on December 18 and 22, 1997 for the chemical analyses described in Section 2.2. Diesel- and heavy oil-range hydrocarbons were detected in ground water samples B-30, B-31, B-34 and B-36 at concentrations ranging from 1.63 to 3.4 milligrams per liter (mg/I), which exceeds the MTCA Method A cleanup level (1 mg/I). Additionally, PCBs and cPAHs were detected in ground water sample B-34 at concentrations [(0.260 and 0.821 micrograms per liter (µg/1), respectively] exceeding the MTCA Method A cleanup level (0.1 µg/l) for these compounds. PCBs also were detected at a concentration (2.82 µg/l) exceeding the MTCA Method A cleanup level in the ground water sample obtained from B-36. Methylene chloride was detected in the ground water sample obtained from boring B-32. The methylene chloride in the B-32 sample was identified as a laboratory contaminant by the laboratory. Other HVOCs were not detected in the ground water sample obtained from B-32. Other analytes were not detected at concentrations exceeding MTCA cleanup levels in the ground water samples obtained from the borings and MW-10. It is our experience that chemical analytical results from direct-push borings should be used only as a screening tool because they generally are biased high. Therefore, monitoring wells GMW-1, GMW-4, and GMW-6 were constructed to further evaluate ground water conditions in the vicinity of B-30, B-31, B-34 and B-36. Ground water samples were obtained from GMW-1 through GMW-6 (on-site) and GMW-7 (off-site) on February 20, 1998 and submitted for the chemical analyses described in Section 2.2. Diesel- and heavy oil-range hydrocarbons were detected in GMW-2 at concentrations of 1.37 and 12.27 mg/I, respectively, which exceed the MTCA Method A cleanup level of 1.0 mg/I. GMW-7 is located downgradient of the site, immediately adjacent to numerous utility trenches beneath Talbot Road. Additionally, PCBs were detected in GMW-4 at a concentration (1.17 µg/I) exceeding the MTCA Method A cleanup level (0.1 µg/I). Other analytes either were not detected or were detected at a concentration less than MTCA cleanup levels in the ground water samples submitted for analysis. Ground water chemical analytical results are presented in Table 5. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. G e o E n g i n e e r s 19 File No. 0186-407-00-1150/042998 9.5 WELL SEARCH GeoEngineers reviewed Ecology's records for water supply wells located within a 1-mile radius of the site. The wells identified are presented in Table 8. The approximate well locations relative to the subject site are presented in Figure 8. The closest water supply wells in Ecology's records are located approximately M-mile northeast (upgradient/cross gradient) of the site. 10.0 CONCLUSIONS GeoEngineers has performed a Phase I/II ESA of PSE's Grady Way Complex property located at 620 South Grady Way in Renton, Washington. The Phase I ESA portion of our study was conducted in general accordance with the scope and limitations of ASTM E 1527-97. Based on the ESA results, soil and ground water contamination of regulatory significance appears to be limited to portions of the southern third of the site as shown in Figure 9. The results of our studies indicate that the potential for existing soil and/or ground water contamination of regulatory significance in the northern portion of the site is low. The results of our ESA indicate that soil and ground water contamination is present at concentrations of regulatory significance at the following specific locations in the southern portion of the site (Figure 9): • Diesel- and heavy oil-range hydrocarbons were detected in a ground water sample obtained from GMW-2 at a concentration (1.37 mg/I) slightly exceeding the MTCA Method A cleanup level (1 mg/I). • PCBs were detected at concentrations (1.33 to 1.85 mg/kg) slightly exceeding the MICA Method A cleanup level (1 mg/kg) in soil samples obtained from three locations (B-7 at 0.5 foot bgs, B-34 at 0.5 foot bgs and TP-5 at 4.0 feet bgs). • PCBs were detected at a concentration (1.17 µg/1) exceeding the MTCA Method A cleanup level (0.1 µg/I) in ground water obtained from GMW-4. • Carcinogenic PAHs (cPAHs) were detected at concentrations (1.70 to 2.46 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) in shallow (0.5 foot bgs) soil samples obtained from three locations (B-19, B-23 and B-29). • CPAHs were detected at concentrations (2.87 to 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) in two of the six sediment samples obtained from catch basins. Additional localized residual PCB and/or PAH concentrations exceeding applicable cleanup levels may be present immediately adjacent to portions of the on-site catch basins, stormwater conveyance pipes and/or buried transformers, if present. The extent of residual cPAH and/or PCB concentrations exceeding applicable cleanup levels in the vicinity of B-7, B-19, B-23, B-29, B-34 and TP-5 was not filly evaluated by our study. However, based on our experience with these compounds at other similar PSE sites and GeoEngineers 20 File No. 0186-407-00-1150/042998 the soil and ground water analytical results, we expect that the areas of contaminant concentrations exceeding cleanup levels would be localized. Other soil samples obtained near the areas of PCB and cPAH cleanup level exceedances identified above did not contain concentrations of these compounds that exceed applicable cleanup levels. Our conceptual volume estimate of soil containing PCB and cPAH concentrations exceeding MTCA Method A cleanup levels in the southern portion of the site is 500 cubic yards. This estimate assumes that the PCB and/or cPAH concentrations of regulatory significance are limited to an area within approximately 20 feet of sample locations B-7, B-19, B-23, B-29, B-34 and TP-5-4. The actual volume may vary significantly from this conceptual estimate. Chemical analysis did not detect contaminant concentrations exceeding applicable cleanup levels in 73 of the 81 soil/sediment samples and four of the six on-site ground water.samples submitted for chemical analysis. Diesel- and heavy oil-range hydrocarbons either were not detected or were detected at concentrations less than the Model Toxics Control Act (MTCA) Method A cleanup level (1 mg/I) in ground water samples obtained from the monitoring wells on-site with the exception of GMW-2. MTCA Method B cleanup levels were calculated in accordance with Ecology's Interim TPH Policy for direct contact and soil-to-ground water exposure pathways (Appendix E) using soil analytical data from the site. The MTCA Method B cleanup levels range from 3,432 mg/kg to 3,971 mg/kg for the various types of petroleum hydrocarbons present in soil at the site. Petroleum hydrocarbons were detected in soil at concentrations less than the most conservative MTCA Method B cleanup level (3,432 mg/kg) calculated for the site. The Interim TPH Policy does not specify an approach for evaluating the potential risk caused by hydrocarbon vapors, therefore the soil-to-air pathway was not specifically evaluated during this study. However, significant concentrations of volatile compounds typically are not associated with transformer oils and hydraulic/lube oils like those detected at the site. Furthermore, benzene was not identified as a contaminant on the site. Institutional controls could be implemented at the site to protect human health from hydrocarbon vapors if future regulatory policy requires specific mitigating measures for protection of human health through the soil-to-air pathway. Significant concentrations of diesel- and heavy oil-range petroleum hydrocarbons were detected in soil and ground water obtained from monitoring well/boring GMW-7 located in Talbot Road, immediately downgradient from the southern portion of the site. In our opinion the source for the petroleum-related soil and ground water contamination detected in GMW-7 is not likely located on the subject site because petroleum-related contamination of regulatory significance was not detected in the two on-site wells (GMW-5 and GMW-6) located closest to, and upgradient of, GMW-7. Our study did not identify evidence concerning the specific source of the petroleum hydrocarbons detected in GMW-7.

GeoEngineers makes no warranties or guarantees regarding the accuracy or completeness of information provided or compiled by others. The information presented in this report is based on the above-described research and our site visits. GeoEngineers has relied upon information provided by others in our description of historical conditions and in our review of regulatory databases and files. The available data do not provide definite information with regard to all past uses, operations or incidents at the site or adjacent properties. No ESA can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions in connection with a property. Our conclusions are based on chemical analytical results from widely spaced soil and ground water sample locations. There is always a potential that areas with contamination that were not identified during this ESA exist at the site or in the study area. Further evaluation of such potential would require additional research, subsurface exploration, sampling and testing. Some substances may be present in the site vicinity in quantities or under conditions that may have led, or may lead, to contamination of the subject site, but are not included in current local, state, or federal regulatory definitions of hazardous substances or do not otherwise present current potential liability. GeoEngineers cannot be responsible if the standards of all appropriate inquiry or regulatory definitions of hazardous substances change, or if you are required to meet more stringent standards in the future. GeoEngineers has performed this Phase I ESA of the Puget Sound Energy property at 620 South Grady Way, Renton Washington within the limitations of scope, schedule and budget and in general accordance with ASTM E 1527-97.

In accordance with 40 CFR 300.425.(e),sites may be deleted from the NPL where no further response is appropriate. NFRAP: No Further Remedial Action Planned Source: EPA/NTIS Telephone: 703-413-0223 NFRAP: As of February 1995,CERCLIS sites designated"No Further Remedial Action Planned"(NFRAP)have been removed from CERCLIS. NFRAP sites may be sites where,following an initial investigation,no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL,or the contamination was not serious enough to require Federal Superfund action or NPL consideration. EPA has removed approximately 25,000 NFRAP sites to lift the unintended barriers to the redevelopment of these properties and has archived them as historical records so EPA does not needlessly repeat the investigations in the future. This policy change is part of the EPA's Brownfields Redevelopment Program to help cities,states,private investors and affected citizens to promote economic redevelopment of unproductive urban sites.

The samples were obtained by chipping the concrete surface into approximate 1/2-inch pieces using a roto-tap hammer and a chisel. The concrete chips were placed in clean glass jars supplied by the analytical laboratory and were submitted to North Creek Analytical Laboratory in Bothell, Washington for chemical analysis of PCBs. The laboratory crushed the samples prior to analysis. The concrete samples were kept in a cooler and chain-of-custody procedures were followed in transporting the samples to the analytical laboratory. SOIL SAMPLING PROGRAM An engineer from GeoEngineers obtained near-surface soil samples at approximately 2-foot-depth intervals from 38 direct-push borings (B-1 through B-38) and 5 test pits (TP-1 through TP-5) on December 18 and 22, 1997; 7 hollow-stem auger borings (GMW-1 through GMW-7) on February 18 and 19, 1998; and 9 hand auger borings (B-39 through B-47) on February 23, 1998 to depths ranging from approximately 0.5 to 12 feet beneath the ground surface at the approximate locations shown in Figure 4. The direct-push borings were completed using equipment owned and operated by TEG. The test pits were completed using a backhoe owned and operated by SME. The hollow-stem auger borings were completed using a drill rig owned and operated by GeoTech Explorations. The hand auger borings were completed by an engineer from GeoEngineers. Soil cuttings from the hollow-stem auger borings are stored on-site in labeled 55-gallon drums. Soil samples GC-1 and GC-2 were composites of discrete samples obtained from the mine tailings located east of the security fence. Discrete samples SS-1 through SS-3 were combined to form GC-1. Discrete samples SS-4 through SS-6 were combined to form GC-2. The mine tailings samples were obtained with a steel spoon and placed into a plastic bag and shaken for compositing. Soil sampling equipment was decontaminated between each sampling attempt using a Liquinox wash and a distilled water rinse. Decontamination water was placed on-site in labeled 55-gallon drums. Soil samples obtained from the explorations were field screened to evaluate for the potential presence of petroleum hydrocarbons and classified in accordance with ASTM D2488-90. An explanation of soil classification and boring log symbols is presented in Figures C-1 and C-2. Soil samples submitted for chemical analysis are denoted on the logs with "CA". Boring logs and test pit logs are presented in Figures C-3 through C-59. GeoEngineers C-1 File No. 0186-407-00-1150/042998 Samples selected for analysis were placed in laboratory supplied jars. The jars were filled completely, tightly sealed and placed in a cooler for transport to the analytical laboratory, North Creek Analytical, of Bothell, Washington. Chain-of-custody procedures were followed in transporting the samples to the analytical laboratory. SEDIMENT SAMPLING Six discrete sediment samples were obtained from selected storm water catch basins on the site. Two discrete sediment samples were obtained from the storm water pond located in the eastern portion of the site. The sediment samples were obtained with a stainless steel spoon. Soil sampling equipment was decontaminated between each sampling attempt using a Liquinox wash and a distilled water rinse. Decontamination water was placed on-site in labeled 55-gallon drums. The sediment samples were placed in laboratory supplied jars filled completely to eliminate headspace. The sample jars were placed in a cooler for transport to the analytical laboratory, North Creek Analytical, of Bothell, Washington. Chain-of-custody procedures were followed in transporting the samples to the analytical laboratory. FIELD SCREENING METHODS An engineer from GEI field screened soil samples from the site. Field screening results are used as a general guideline to delineate areas of possible petroleum-related contamination. In addition, screening results can be used to aid in the selection of soil samples for chemical analysis. The screening methods used included (1) visual screening and (2) water sheen screening. Visual screening consists of inspecting the soil for stains indicative of petroleum-related contamination. Visual screening is generally more effective when contamination is related to heavy petroleum hydrocarbons, such as motor oil, or when hydrocarbon concentrations are high. Water sheen screening is a more sensitive method that has been effective in detecting contamination at concentrations less than regulatory cleanup levels. However, field screening results are site-specific. The effectiveness of field screening varies with temperature, moisture content, organic content, soil type and type and age of contaminant. The presence or absence of a stain or sheen does not necessarily indicate the presence or absence of petroleum hydrocarbons. Water sheen screening involves placing soil in water and observing the water surface for signs of sheen. Sheen screening may detect both volatile and nonvolatile petroleum hydrocarbons. Sheen classifications are as follows: No Sheen (NS) No visible sheen on water surface. Slight Sheen (SS) Light, colorless, dull sheen; spread is irregular, not rapid; sheen dissipates rapidly. Natural organic matter in the soil may produce a slight sheen. G e o E n g i n e e r s C-2 File No. 0186407-00-1150/042998 Moderate Sheen (MS) Light to heavy sheen; may have some color/iridescence; spread is irregular to flowing, may be rapid; few remaining areas of no sheen on water surface. Heavy Sheen (HS) Heavy sheen with color/iridescence; spread is rapid; entire water surface may be covered with sheen. Field screening results are presented in Table 2 and in the boring and test pit logs (Figures C-3 through C-59). MONITORING WELL CONSTRUCTION A ground water monitoring well was constructed in borings GMW-1 through GMW-7 at the completion of drilling. Two-inch-diameter, Schedule 40 PVC (polyvinyl chloride) pipe was installed in the borings. The lower portion of the PVC pipe is machine-slotted (0.02-inch slot width) to allow entry of water into the well casing. Medium sand was placed in the borehole annulus surrounding the slotted portion of the well. The well casing is protected within a surface monument and contains a lockable compression cap. Monitoring well construction is shown in Figures C-50 through C-56. GMW-1 through GMW-7 were developed by removing five saturated well casing volumes of ground water from the well with disposable polyethylene bailers. Water removed from the well was placed in labeled 55-gallon drum on-site along with water generated during decontamination activities. GROUND WATER ELEVATIONS We measured the elevations of the well casings to the nearest 0.01 foot with an engineer's level and a fiberglass stadia rod on February 19, 1998. Elevations of the monitoring well casing rims and the ground surface adjacent to the monument are based on a benchmark (MW-20, top of casing)with an assumed elevation of 99.97 feet above MSL(mean sea level). The depth to ground water relative to the monitoring well casing rims of MW-4, MW-8, MW-10 and MW-20 was measured on December 22, 1997. Similar measurements were obtained from all accessible wells associated with the site, including GMW-1 through GMW-7, on February 26, 1998. The measurements were made using an electric water level indicator. The water level indicator was decontaminated prior to each measurement with a Liquinox wash solution and a distilled water rinse. The decontamination water is stored on-site in a labeled 55-gallon drum. GROUND WATER SAMPLING Ground water samples were obtained from monitoring well MW-10 and borings B-30 through B-37 on December 22, 1997. Additional ground water samples were obtained from GMW-1 through GMW-7 on February 20, 1998. The water samples were obtained from the monitoring wells using disposable polyethylene bailers after at least three well volumes of water G e o E n g i n e e r s C-3 File No. 0186407-00-1150/042998 1 were removed from each well casing. The water samples were obtained from the direct-push borings using a peristaltic pump attached to disposable polyethylene tubing supplied by the driller. The pump was decontaminated using a Liquinox before sampling each sampling event. New tubing and bailing rope were used for each sampling attempt. The water samples were transferred to laboratory prepared bottles, filled completely to eliminated headspace, and were kept cool during transport to the testing laboratory, North Creek Analytical of Bothell, Washington. Chain-of-custody procedures were observed during transport of the samples to the testing laboratory. Purge and decontamination water from the ground water sampling activities was placed in on-site in labeled 55-gallon drums.

The samples were held in cold storage pending extraction and/or analysis. The analytical results, analytical methods reference and laboratory QA/QC (quality assurance/quality control) records are included in this appendix. The analytical results are also summarized in the text and tables of this report. ANALYTICAL DATA REVIEW The laboratory maintains an internal quality assurance program as documented in its laboratory quality assurance manual. The laboratory uses a combination of blanks, surrogate recoveries, duplicates, matrix spike recoveries, matrix spike duplicate recoveries, blank spike recoveries and blank spike duplicate recoveries to evaluate the validity of the analytical results. The laboratory also uses data quality goals for individual chemicals or groups of chemicals based on the long-term performance of the test methods. The data quality goals are included in the laboratory reports. The laboratory compared each group of samples with the existing data quality goals and noted any exceptions in the laboratory report. Data quality exceptions documented by the laboratory in the laboratory reports are reviewed by GeoEngineers using the applicable data validation guidelines from the following documents: "National Functional Guidelines For Organic Data Review" draft dated 1991 and "Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses" dated 1988. ANALYTICAL DATA REVIEW SUMMARY The laboratory reports did identify some date quality exceptions. However, the data quality exceptions documented in the laboratory reports are not significant Based on our data quality review, it is our opinion that the analytical data are of acceptable quality for their intended use in this report.

S— O /C PAGE OF APPENDIX E INTERIM TPH POLICY APPENDIX E INTERIM TPH POLICY MICA METHOD B CLEANUP LEVEL CALCULATIONS This appendix presents the results of GeoEngineers' calculation of Model Toxics Control Act (MTCA) Method B cleanup levels for diesel- and heavy oil-range hydrocarbons detected in soil at PSE's Grady Way Complex property during the 1997/1998 ESA. The MTCA Method B cleanup levels presented herein were calculated using the Washington State Department of Ecology's (Ecology) Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy). Our Phase I ESA research and chemical analyses indicate that periodic transformer (mineral/insulating) oil leaks from electrical transformers stored in the southern and eastern portions of site during the past 40 years have resulted in residual concentrations of petroleum hydrocarbons in soil. Transformer oil elutes in the diesel- and heavy oil-range when analyzed by gas chromatography. Chemical analysis during Phase II of our study quantified the residual transformer oil-related hydrocarbons in soil at the site either as transformer oil and/or undifferentiated diesel- and heavy oil-range hydrocarbons. Chemical analysis also detected hydraulic/lube oil-range hydrocarbons in some of the soil samples. A specific source of these hydraulic/lube oil-range hydrocarbons was not identified by our study. Recent studies (Insulating Oil Fate and Transport Report, May 1996, prepared for Bonneville Power Administration et. al. by CH2M Hill) have shown that the more toxic constituents typically associated with many petroleum products such as semi-volatile organic compounds, volatile organic compounds and metals are present at trace concentrations or are not detectable in transformer (mineral/insulating) oils. The studies also have shown that transformer oil has a relatively high viscosity, migrates through soil relatively slowly, and has a low potential for volatilization, leaching or transport to ground water. Remediation of petroleum-hydrocarbon spills historically has been completed using the Model Toxics Control Act (MTCA) Method A cleanup levels for petroleum products. The MTCA Method A cleanup levels for petroleum hydrocarbons in soil (200 milligrams per kilogram [mg/kg] for diesel- and heavy oil-range hydrocarbons and 100 mg/kg for gasoline- range hydrocarbons) cannot be adjusted to account for specific properties of petroleum products such as the absence of the more toxic constituents in transformer and hydraulic/lube oils. The Ecology Interim TPH Policy allows for calculation of a MTCA Method B cleanup level for the petroleum product in soil based on the actual constituents present in the petroleum. The Interim TPH Policy methodology was used to (1) calculate site specific petroleum hydrocarbon cleanup levels, and (2) evaluate the regulatory significance of residual petroleum hydrocarbons in soil at the subject site. A detailed discussion of the Interim TPH Policy methods is presented later in this appendix. GeoEngineers B-1 File No. 0186-407-00-1150/042998 iE CHEMICAL ANALYSES Three soil samples (B-1-3.0, B-32-0.5 and GMW-4-6.0) were obtained by GeoEngineers, from portions of the site where chemical analysis indicated the presence of residual petroleum hydrocarbons. The petroleum hydrocarbons in B-1-3.0 were quantified as hydraulic/lube oil. The petroleum hydrocarbons in B-32-05 were quantified as transformer (mineral/insulating) oil. The petroleum hydrocarbons in GMW-4-6.0 were quantified as undifferentiated diesel- and heavy oil-range hydrocarbons that we have attributed to transformer oil. The approximate locations of these soil samples are shown on Figure 5 of the report. The soil samples were submitted to North Creek Analytical of Bothell, Washington for one or more of the following chemical analyses: diesel- and heavy oil-range petroleum hydrocarbons by Ecology Method NWTPH-D extended and benzene, ethylbenzene, toluene and xylenes (BETX), methylene tert- butyl ether (MTBE), naphthalene, volatile petroleum hydrocarbon (VPH) fractions and extractable petroleum hydrocarbon (EPH) fractions using Ecology Interim TPH Policy methods. The chemical analytical results considered in the Interim TPH Policy calculations for this study are presented in Table E-1. Laboratory reports are presented in Appendix D. Hydraulic/lube oil was detected in B-1-3.0 at a concentration of 213 mg/kg. Aliphatic EPHs were detected in the EC (equivalent carbon) 12-16, EC16-21, and EC21-34 ranges. Aromatic EPHs were detected in the EC16-21 and EC21-34 ranges. Polynuclear aromatic hydrocarbons (cPAHs) were detected in the B-1-3.0 sample at concentrations less than applicable MTCA cleanup levels. Transformer oil was detected in B-32-0.5 at a concentration of 1,100 milligrams per kilogram (mg/kg). Aliphatic EPHs were detected in the EC12-16, EC16-21, and EC21-34 ranges. Aromatic EPHs were detected in the EC16-21 and EC21-35 ranges. Polynuclear aromatic hydrocarbons (PAHs) were not tested in the B-32-0.5 sample because PAH data was obtained for the higher concentration of transformer oil-related hydrocarbons detected in GMW-4-6.0. Undifferentiated diesel- and heavy oil-range hydrocarbons were detected in GMW-4-6.0 at concentrations of 1,140 and 671 mg/kg, respectively. Aliphatic VPHs were not detected in the GMW-4-6.0 sample. Aromatic VPHs were detected in the EC8-10 and EC10-12 ranges. Aliphatic EPHs were detected in the EC12-16, EC16-21, and EC21-34 ranges. Aromatic EPHs were detected in the EC16-21 and EC21-34 ranges. BETX and MTBE were not detected in GMW-4-6.0. PAHs either were not detected or were detected at concentrations less than applicable MTCA cleanup levels in the GMW-4-6.0 sample. MTCA METHOD B SOIL DIRECT CONTACT CALCULATIONS Petroleum products, including transformer oil, hydraulic/lube oil and other diesel- and heavy oil-range hydrocarbons, contain multiple fractions and individual compounds that have associated noncarcinogenic health effects. MTCA stipulates that individual hazard quotients GeoEngineers E-2 File No. 0186-407-00-1150/042998 associated with these fractions are additive, and that the total hazard index (the sum of all individual hazard quotients) should not exceed 1.0 for the risk to be considered acceptable. We calculated that the hazard index for the hydraulic/lube oil in soil sample B-1-3.0 is 0.06 as shown in Table E-2. Carcinogenic PAHs were not detected at concentrations exceeding the MTCA Method A cleanup level in B-1-3.0. A site-specific Method B soil cleanup level protective of human health direct contact (noncarcinogen) exposures was calculated for the hydraulic/lube oil using the MTCA Method B equations and the reference dose values as shown in Table E-3. The Method B cleanup level we calculated for hydraulic/lube oil in soil at this site is 3,432 mg/kg. We calculated that the hazard index for the transformer oil in soil sample B-32-0.5 is 0.19 as shown in Table E-4. A site-specific Method B soil cleanup level protective of human health direct contact (non-carcinogen) exposures was calculated for transformer oil using the MTCA Method B equations and the reference dose values as shown in Table E-5. The Method B cleanup level we calculated for petroleum hydrocarbons quantified as transformer oil in soil at this site is 3,971 mg/kg. We calculated that the hazard index for the transformer oil related hydrocarbons quantified in the diesel- and heavy oil-ranges in soil sample GMW-4-6.0 is 0.38 as shown in Table E-6. Carcinogenic compounds were not detected at concentrations exceeding applicable MTCA cleanup levels in GMW-4-0.0. A site-specific Method B soil cleanup level protective of human health direct contact (noncarcinogen) exposures was calculated for the transformer oil related hydrocarbons in GMW-4-6.0 using the MTCA Method B equations and the reference dose values as shown in Table E-7. The Method B cleanup level we calculated for petroleum hydrocarbons in GMW-4-6.0 is 3,965 mg/kg. The Method B cleanup levels we calculated are based on (1) evaluation of the direct contact exposure pathway, and (2)the ratio of aliphatic to aromatic constituents. POTENTIAL SOIL-TO-GROUND WATER TRANSPORT OF HYDROCARBONS The Interim TPH Policy also requires that soil contamination be evaluated relative to its potential to migrate to ground water. In accordance with the Policy, the evaluation of this fate and transport pathway was based on a determination of whether TPH remaining in vadose zone soil could cause exceedance of the MTCA Method A ground water cleanup level for TPH of 1 milligram per liter (mg/1). The concentration of TPH partitioning from soil to soil pore water was estimated using Raoult's Law for the hydrocarbons detected in B-1-3.0, B-32-0.5 and GMW-4-6.0. Raoult's Law is used to estimate resultant chemical concentrations dissolved in water when more than one chemical compound (TPH fraction) is present in soil. Each TPH fraction has a different solubility in water. Based on the relative concentration of each fraction, Raoult's Law was used to estimate the resultant concentration of TPH in pore water. Consistent with the Interim TPH Policy, the estimated concentration of TPH in pore water using Raoult's Law was then assumed to directly enter the ground water (assumes that G e o E n g i n e e r s E-3 File No. 0186.407-00-1150/042998 contaminated soil is in direct contact with ground water). Once the pore water enters the ground water, it is assumed under the Interim TPH Policy that the concentrations of dissolved TPH will be diluted by 20 times before reaching a drinking water well. This diluted concentration of dissolved hydrocarbons is compared to the MTCA Method A ground water cleanup level for TPH of 1 mg/1. Using the methods described above and the EPH fraction data for B-1-3.0, the predicted hydraulic/lube oil concentration in ground water is approximately 2.9 x 10"3 mg/I as shown in Table E-8. This concentration is significantly less than the MTCA Method A cleanup level for TPH of 1 mg/1 Using the methods described above and the EPH faction data for B-32-0.5, the predicted transformer oil concentration in ground water is approximately 4.1 x 10-3 mg/1 as shown in Table E-9. This concentration is significantly less than the MTCA Method A cleanup level for TPH of 1 mg/l. Using the methods described above and the transformer oil-related hydrocarbon fractions detected in GMW-4-6.0, the predicted total diesel- and heavy oil-range hydrocarbon concentration in ground water is approximately 5.1 x 10"3 mg/I as shown in Table E-10. This concentration is significantly less than the MTCA Method A cleanup level for TPH of 1 mg/1. INTERIM TPH POLICY METHODS The MTCA cleanup regulations require that the evaluation of soil contamination and determination of soil cleanup levels be based on consideration of direct contact and on protection of ground water. Similarly, the Interim TPH Policy requires consideration of both components in evaluating petroleum contamination and arriving at a soil cleanup level. To evaluate the level of contamination and calculate a soil cleanup level for the site's transformer oil in accordance with the Interim TPH Policy, identification of the petroleum product hydrocarbon fractions and quantification of their toxicity (using surrogates) and transport characteristics were required. Considerations of current and future site use also were necessary to apply the appropriate MTCA method. For this site, we made the most conservative assumption that the site must meet residential cleanup standards; therefore, MTCA Method B was used for evaluation of contamination and in calculating a soil cleanup level. The MTCA Method B formula for evaluating soil contamination and calculating a human health risk-based soil cleanup based on direct contact, as applied in the Interim TPH Policy, considers only the soil ingestion exposure pathway. This was considered sufficient for contamination evaluation and calculation of transformer oil and hydraulic/lube oil cleanup levels in soil at this site. The potential for inhalation of vapors from residual transformer oil and hydraulic/lube oil in site soils is considered negligible because of the low volatility of these hydrocarbons. Soil-to-ground water transport of transformer oil and subsequent ingestion of ground water also was considered in our assessment. The reader is referred to the Interim TPH G e o E n g i n e e r a E-4 File No. 0186.407-00-1150/042998 Policy (Ecology Publication ECY 97-600) for background information and assumptions that pertain to the use of the Interim TPH policy. SURROGATE APPROACH Petroleum products typically are composed of thousands of individual chemicals. Toxicity criteria that relate the intake (dose) of a chemical to a response are available for only a handful of the individual chemicals that may be present in petroleum products. A cleanup level cannot be calculated for individual chemicals (or for petroleum products) unless a toxicity criterion, such as a reference dose for a non-carcinogen or a potency factor for a carcinogen, is available. The Interim TPH Policy uses a surrogate approach to account for compound-specific data that is not yet available. In the surrogate approach, a reference compound is identified as a representative of individual petroleum hydrocarbon fractions. These reference compounds are selected because their toxicity is relatively well characterized in that either a reference dose or potency factor is available, or a dose-response value can be developed from available toxicity data. The toxicity criterion identified for the reference compound is then assumed to represent a surrogate toxicity criterion for the associated hydrocarbon fraction. For the purpose of identifying surrogate toxicity criteria for hydrocarbon fractions, petroleum hydrocarbons are divided into broad chemical classes. Surrogate toxicity criteria are then identified for each group of compounds using the methods described above. Ecology has selected one compound representing the aliphatic fractions (n-hexane) and one compound representing the aromatic fractions (pyrene) that likely have the most conservative toxicity criteria. Surrogate criteria for other hydrocarbon fractions are likely multiples of these. Until sufficient data are made available for developing surrogate toxicity criteria for the other hydrocarbon fractions, the Ecology Interim TPH Policy requires that (1) all aliphatics be grouped together, (2) all aromatics be grouped together and (3) the aliphatic and aromatic groups be represented by the toxicity criteria for n-hexane and pyrene, respectively. This surrogate approach was used in our calculation of the Method B cleanup level for the petroleum hydrocarbons in site soils based on direct contact. The surrogate method used in the Interim TPH Policy for evaluation of contamination and in calculating petroleum hydrocarbon cleanup levels does not account for the noncarcinogenic toxicity contribution of ethylbenzene, toluene, and xylene. It also does not account for the carcinogenic health effect contribution from benzene and carcinogenic PAHs that may be present in the petroleum product. These compounds are quantified and evaluated separately, and cleanup levels are calculated for each compound using their specific reference dose or potency factors. Evaluation of petroleum contamination and calculation of Method B cleanup levels completed for this study accounts only for petroleum hydrocarbons in the absence of these compounds. G e o B n g i n e e r a E-S File No. 0186-407-00-1150/042998 No historical sources of benzene, ethylbenzene, toluene and xylenes were identified in the southern and eastern portions of the site. during our studies. Additionally, benzene ethylbenzene, toluene and xylenes were not detected in GMW-4-6.0. Residual carcinogenic PAHs were detected at concentrations exceeding the MTCA Method A cleanup level for cPAHs in three of the soil samples (B-19, B-23 and B-29) submitted for analysis. The source of these cPAHs are preservatives on power poles formerly stored at the site. They do not appear to be related to the residual transformer and hydraulic/lube oil detected in many of the soil samples. The hydrocarbon fractions and their associated surrogate toxicity criterion values for the Ecology Interim TPH Policy are summarized in Tables E-2 through E-7. The hydrocarbon compounds are all considered non-carcinogenic, based on the toxicity information currently available. Therefore, only reference dose (ORFD) values are provided. FATE AND TRANSPORT The fate and transport of hydrocarbons in the subsurface is a significant component of the Interim TPH Policy. Similar to the approach discussed above for toxicity, surrogate physical and chemical properties of different hydrocarbon fractions are used to represent and evaluate hydrocarbons movement through and into soil and water. Based largely on studies completed by the National TPH Criteria Working Group, the Ecology Interim TPH Policy uses six aliphatic fractions, five aromatic fractions, and benzene and toluene in evaluating the fate and transport of petroleum products. The TPH Criteria Working Group grouped the numerous TPH constituents into the aliphatic and aromatic fractions based on the similarity of their chemical properties. Constituent chemical properties such as equivalent carbon number, soil sorption coefficient, soil organic-carbon fractional content, octanol-water partition coefficient, and Henry's Law Constant, dictate how they are transported in different media and were used to identify the hydrocarbon fractions. Although MTCA requires that each potential transport pathway of concern be evaluated, the Interim TPH Policy specifically mentions two transport pathways: (1) soil-to-ground water and (2) soil-to-air. An evaluation of the soil-to-ground water pathway determines what petroleum concentrations in soil may be left in place while being protective of ground water. Four methods of evaluating soil-to-ground water cleanup levels are described in the Ecology Interim TPH Policy. The method used for this study was soil/pore water partitioning (Raoult's Law) as summarized in Tables E-8 through E-10. The methods with which to evaluate risks to human health or the environment associated with hydrocarbons migrating from subsurface soils in the vapor phase have not yet been defined in the Interim TPH Policy. Additionally, significant concentrations of volatile hydrocarbons typically are not associated with transformer oil and hydraulic/lube oil detected in soil at the site. Therefore, we did specifically evaluate the soil to vapor exposure pathway during this ESA. G e o E n g i n e e c • E-6 File No. 0186-407-00-1150/042998 CONCLUSIONS Chemical analytical results indicate that residual transformer oil-related hydrocarbons and hydraulic/lube oil-range hydrocarbons detected in site soil are less than calculated MTCA Method B cleanup levels for these hydrocarbons and are protective of human health for the direct contact and soil-to-ground water exposure pathways in the absence of carcinogenic PAHs. INTERIM TPH POLICY LIMITATIONS Regulatory policy regarding risk-based evaluations of petroleum hydrocarbon contamination continues to be formulated by Ecology. The Interim TPH Policy is a conservative and temporary measure intended to allow for the use of a risk-based approach to petroleum hydrocarbons while final policy is developed. The policy described herein is subject to future regulatory revisions.

Contaminated Soil Remediation Specification Page 17 PUGET SOUND ENERGY Environmental Services P. O. Box 97034-9734 Bellevue, WA 98009-9734 EROSION AND SEDIMENTATION CONTROL PLAN FOR GRADY WAY COMPLEX PROJECT July 1, 1998+ Puget Sound Energj GENERAL The following Sedimentation and Erosion Control Plans are for the removal of USTs, soil and sediment remediation, and site restoration at: PUGET SOUND ENERGY Grady Way Complex 620 South Grady Way Renton, Washington Construction activities will involve removal of three on-site USTs, one fuel island, associated fuel piping, concrete traffic slabs and anchoring systems, as summarized in the Specification. Additionally, the Contractor will (1) remove a stormwater drainage system and associated sediment, and replace the stormwater system, (2) complete remedial excavation to remove contaminated soil at specified locations, and (3) restore the site surface to original grade and conditions. Potentially clean overburden and contaminated soil excavated during all tasks of this project will temporarily be stockpiled on site. Stockpiled contaminated soil will be transported off-site for disposal at an appropriate, licensed facility as directed by the Owner. Confirmatory sampling and analysis will be conducted to verify that soil with contaminant concentrations exceeding applicable Model Toxics Control Act (MTCA) cleanup levels has been successfully removed from the site. Uncontaminated materials, such as building material, overburden soil unsuitable for backfill and broken concrete or asphalt, will be transported to a demolition landfill and disposed in an approved manner. All costs under this Sedimentation and Erosion Control Plan shall be included in the base bit! lump sum price in the Schedule of Bid Prices. SOIL STOCKPILE PLAN Soil excavated during the remediation process will be classified by the Consultant i i contaminated or uncontaminated and will be handled and stockpiled separately. Excavated so;l not suitable for backfill will be loaded and transported off-site in a timely manner. Due to th' uncertainties of transport logistics, short-term stockpiling of the contaminated soil may b.; required on a temporary basis. Stockpiles will be located within fenced areas at the site 1) prevent uncontrolled access to the soil. Contaminated and uncontaminated stockpiles will not l located within 100 feet of any surface water course or be over 10 feet in height. Stockpiled contaminated soil will be placed on an impervious barrier or bottom liner. At the edges of di stockpile, the bottom liner will be bermed to prevent contamination of the ground surface wir'i Erosion and Sedimentation Control Plan Page 1 Puget Sound En erg} soil or run-off from the stockpile. The bottom liner will consist of 10-mil-thick polyethylene, (Visqueen) or equivalent material. Stockpiles also will be covered with an impervious liner to prevent rainwater infiltration, and/or wind-borne dust. The cover will be weighted with tires, or other available heavy material to provide protection from wind. The stockpile may be covered with a liner meeting the same specifications as the bottom liner. Contaminated soil will be placed on the bottom liner in a way such that the liner remains intact, When material is added or removed from a stockpile, care will be exercised such that only the working face of the pile is uncovered. At the end of each work day, the stockpile will be covered and secured. EROSION CONTROL All stockpiled soil will be covered with an impermeable barrier (liner) for protection from wind, rain, and other natural erosion processes. The stockpiling plan effectively prevents erosion problems from occurring with stockpiled soil. The anticipated remedial excavations should not result in soil erosion by natural processes because the subject site is relatively flat. The size of each excavated area will be controlled such that surface areas of exposed soil surrounding the excavations will be open for only short time periods (2-15 days each). A silt fence will be placed along the site boundary adjacent to excavation E-10 to prevent surface water runoff from transporting sediment off-site. Silt fencing will be utilized in other portions of the site, if it becomes apparent that runoff is an issue in these areas. SEDIMENTATION CONTROL All remaining storm drains near the excavations or stockpiles will be protected with a filte.. fabric silt barrier to prevent the accumulation of sediment. Straw bales or other control method, will be utilized, as required, to prevent surface water transport of soil or sediment from th,, excavation, stockpiling, hauling, or soil loading areas on the work site. The area surrounding the soil excavation, hauling, and loading areas will be inspected and cleaned daily and upon completion of removal/remediation activities. Erosion and Sedimentation Control Plan Pagc 2 Puget Sound Energ) GROUND WATER HANDLING Excavation of contaminated soil may require continuation to a depth below the ground watei table. We anticipate that ground water will be encountered beneath the site at depths ranging between approximately 5 and 8 feet below ground surface. Excavation of contaminated soil in the upper 1 to 2 feet of the aquifer will be performed at the discretion of the Owner. Such excavation will proceed only if it can be completed without generating an excessive volume of contaminated water or if the soil removed does not itself contain excessive water. Soil with free water drainage will not be placed on the soil stockpiles. If excessive water in excavated soil cannot be avoided, then dewatering will be necessary Dewatering will be accomplished by excavating a deeper pit in one corner of the excavation and installing a temporary dewatering well. The well may consist of either a slotted pipe casing wrapped in filter fabric and surrounded with pea gravel, a 55-gallon drum filled with pea gravel, or other design as approved by the Owner. Water will be withdrawn through the casing or drum and placed in temporary containment, such as totally-enclosed holding tanks. Ground water from the excavation will be allowed to stand for settlement of suspended solids, followed by transfer to a second tank, if necessary, for batch sampling and testing by the Consultant and appropriate discharge or disposal. Collected solids or "bottoms" also will be sampled and tested by the Consultant and disposed in an approved manner upon completion of remediation activities. SOIL STABILIZATION Should excavated soil contain excessive water it will not be stockpiled without stabilizing the free liquids. Such soil will be mixed with bentonite clay, fly ash, or other Owner approved material to adequately absorb moisture. The stabilizing material may be introduced to the soil in the excavation or an adjacent dump truck and mixed using the excavation machinery to promote water absorption.

REQUIREMENTS 1. Aggregate for asphalt concrete shall be Washington State Department of Transportation (WSDT) Class B in accordance with WSDT Standard Spec.9-03.8. - 2. Paving asphalt shall be viscosity grade AR-4000W in accordance with WSDT Standard Spec.9-02.1(4). 3. Tack coat shall be CSS-1 or CSS-1h asphalt emulsion in accordance with WSDT Standard Spec. 9-02.1(6). TESTS AND INSPECTION The top or wearing surface, when finished, shall be of uniform texture, smooth, true to grade, and free from defects of all kinds. The smoothness shall be such that, when tested with a ten (10) foot straightedge placed on the surface with its centerline parallel to the centerline of the pavement, the maximum deviations of the surface from the edge of the straightedge does not exceed one-tenth (0.1) inch at any point on the surface. PROCEDURE 1. Asphalt concrete shall be placed only during dry weather. No asphalt concrete shall be placed when the atmospheric temperature is below 40 degrees Fahrenheit. 2. The asphalt concrete mixture shall be transported to the place of installation in suitable dump trucks, each load being covered with a tarpaulin while in transit to minimize heat loss to the mixture. 3. The asphalt concrete shall only be placed on properly sterilized and compacted base, which is dry, clean, and true to line and grade. 4. The temperature of the asphalt concrete when placed shall be not less than 250 degrees Fahrenheit. 5. The asphalt concrete course may be spread and finished by hand methods, using hot rakes and other suitable tools, and checking the accuracy of surface grade by means of suitable templates; or it may be spread and finished by special spreading and finishing equipment designed and operated such that the finished surface of the course strikes off at required grade. 6. Immediately following spreading, the asphalt concrete shall be compacted by rolling with a self-prop''Iled roller of sufficient weight to compact the mixture to the required density while it it still in a malleable state. Rolling shall commence at the outside edges of the strip being paved and shall progress towards the cen- ter of the strip, allowing the compression wheels to overlap, by half their width, the area covered on the preceding pass. Rolling shall continue until the asphalt concrete has been compressed to a degree of compactness not less than 92% as determined by AAHSTO T230. Areas inaccessible to the power roller shall be smoothed with hot smoothing irons, and compacted with hot iron tampers. POWER Standards Manual 8350.0050 PAGE 2 of 2 Asphalt Paving Installation REV.O NOV. 12, 1991 7. The placing of asphalt concrete shall be as continuous as possible, and the roller shall pass over the un- protected end of the freshly laid mixture only when the laying of the course is discontinued long enough as to permit the mixture to become chilled. When the work is resumed, the material previously laid shall be cut back so to produce a lightly beveled edge for the full thickness of the course. The old material which has been cut away shall be removed from the site and new mix shall be laid against the fresh cut. Hot smoothing irons can be used to seal the joint. NOTE: Do not over heat the new joint with the smoothing irons as that can C2se the joint not to-seal Properly. 8. The asphalt concrete pavement shall be placed in two lifts and, unless otherwise specified, shall be three (3) inches thick after compactness. A tack coat must be applied between paving courses in the amount of 0.02 to 0.06 gallons per square yard. 9. Where the asphalt concrete is to come in contact with Portland cement concrete, the Portland cement concrete shall be lightly sprayed with hot asphalt immediately before the asphalt concrete is placed. As- phalt or asphalt stains which come upon exposed surfaces of Portland cement concrete shall be promptly and completely removed. 10. Traffic not necessary for construction purposes shall not be allowed to come upon the pavement until it has completely cooled and set.

Our Phase I ESA research indicated that the first recorded site use was a coal mining operation in the late 1800s. PSE purchased the site around 1903. PSE's site uses have included transformer storage and maintenance, vehicle fueling and maintenance and storage of power poles treated with preservative. The site currently contains three buildings, three USTs, a storm water drainage system and various electrical equipment and materials stored and used by PSE. GeoEngineers monitored remedial activities at the site between 1987 and 1990. The remedial activities primarily focussed on the northern half of the property. Approximately 3,750 cubic yards of soil containing residual concentrations of petroleum hydrocarbons associated with former underground storage tanks (USTs) and hydraulic hoists were successfully removed from the site. Remaining petroleum hydrocarbon concentrations detected at the final limits of the hoist and UST remedial excavations were less than applicable cleanup levels. The results of this Phase I ESA indicated that there is a potential for petroleum hydrocarbons, polychlorinated biphenyls (PCBs) and semi-volatile organic compounds (SVOCs) including polynuclear aromatic hydrocarbons (PAHs), at concentrations of regulatory significance in soil and ground water in the southern half of the subject site. Between December 1997 and February 1998, GeoEngineers performed a Phase II ESA consisting of soil, sediment and ground water sampling and analysis to further evaluate the potential presence of hazardous substances. The Phase II ESA included 38 direct-push soil borings, nine shallow hand auger borings, five test pits, seven monitoring wells (six on-site and one off-site), 10 concrete samples, eight sediment samples and two coal mine tailings samples. In general, our Phase II assessment indicates that soil and ground water contamination of regulatory significance appears to be limited to portions of the southern third of the site. Additionally, our studies indicate that the potential for existing soil and/or ground water contamination of regulatory significance in the northern portion of the site is low. A summary of the Phase II ESA analytical results is presented below: • Diesel- and heavy oil-range hydrocarbons either were not detected or were detected at concentrations less than the Model Toxics Control Act (MTCA) Method A cleanup level [1 milligram per liter (mg/I)] in ground water samples obtained from the monitoring wells on-site with the exception of GMW-2 (1.37 mg/I total petroleum hydrocarbons). • Diesel- and heavy oil-range hydrocarbons in soil samples either were not detected or were detected at concentrations [23.4 to 2,120 milligrams per kilogram (mg/kg)] less than the most conservative MTCA Method B cleanup level 3,432 (mg/kg) calculated for GeoEngineers 1 File No. 0186-407-00-1150/042998 this study using Ecology's Interim Interpretive and Policy Statement, aeanup of Total Petroleum Hydrocarbons (Interim TPH Policy). • PCBs were detected at concentrations (1.33 to 1.85 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) at three locations in the southern portion of the site. • PCBs were detected at a concentration [1.17 micrograms per liter (µg/l)] exceeding the MTCA Method A cleanup level (0.1 µg/1) in ground water obtained from GMW-4 in the southern portion of the site. • Carcinogenic PAHs (cPAHs) were detected at concentrations (1.70 to 2.46 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) at three locations in the southern portion of the site. • cPAHs were detected at concentrations (2.87 to 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) in two of the six sediment samples obtained from catch basins in the southern portion of the site. The extent of residual cPAH and/or PCB concentrations exceeding applicable cleanup levels in the vicinity of B-7, B-19, B-23, B-29, B-34 and TP-5 were not fully evaluated by our study. However, based on our experience with these compounds at other similar PSE sites and the soil and ground water analytical results, we expect that the areas of contaminant concentrations exceeding cleanup levels are localized. Our conceptual volume estimate of soil containing PCB and cPAH concentrations exceeding MTCA Method A cleanup levels in the southern portion of the site is 500 cubic yards. The actual volume may vary significantly from this conceptual estimate. Based on the Phase I/II ESA results, it is our opinion that the potential for existing soil and ground water contamination by hazardous substances of regulatory significance on the subject site is low with the exception of the areas noted above. Chemical analysis did not detect contaminant concentrations exceeding applicable cleanup levels in 73 of the 81 soil/sediment samples and four of the six on-site ground water monitoring well samples submitted for chemical analysis. Significant concentrations of diesel- and heavy oil-range petroleum hydrocarbons were detected in soil and ground water obtained from monitoring well/boring GMW-7, located in Talbot Road, immediately downgradient from the southern portion of the site. In our opinion the source for the petroleum-related soil and ground water contamination detected in GMW-7 is not likely located on the subject site because petroleum-related contamination of regulatory significance was not detected in the two on-site wells (GMW-5 and GMW-6) located closest to, and upgradient of, GMW-7. Our study did not identify evidence concerning the specific source of the petroleum hydrocarbons detected in GMW-7. G e o E n g i n e e r e 2 File No. 0186-407-00-1150/042998 ENVIRONMENTAL SITE ASSESSMENT GRADY WAY COMPLEX PROPERTY RENTON, WASHINGTON FOR PUGET SOUND ENERGY 1.0 INTRODUCTION This report summarizes the results of our environmental site assessment (ESA) of Puget Sound Energy's (PSE) Grady Way Complex property located at 620 South Grady Way in Renton, Washington. This property is referred to herein as "the site." The site is shown relative to surrounding physical features in the Vicinity Map, Figure 1. The general layout of the site is shown in Figure 2. We understand that PSE is planning to sell the site. We further understand that the results of the ESA will be used to (1) evaluate environmental liabilities associated with site ownership and (2) identify remedial options to prepare the site for sale. GeoEngineers completed previous site characterization and remedial activities at the site as discussed in Sections 4.0 and 8.3 of this report. The previous studies primarily focussed on conditions in the northern half of the property. Chemical analytical results indicate that the remedial activities were successful in removing soil and ground water contamination of regulatory significance in the northern half of the site. The ESA described herein evaluated environmental conditions on the entire site; however, the Phase II portion of this study focussed on the southern half of the property. 2.0 SCOPE OF SERVICES The purpose of the ESA is to evaluate the presence or likely presence of hazardous substances, including petroleum products that may have resulted from current or past activities on the site or in the site vicinity. GeoEngineers' ESA services were completed in two phases. Phase I consisted of site reconnaissance, regulatory list evaluation and historical research completed in general accordance with American Society for Testing Materials (ASTM) Standard E1527-97 for Phase I ESAs. Phase II consisted of concrete, soil, sediment and ground water sampling and chemical analysis. Our specific scope of services completed for this ESA follows. 2.1 PHASE • Review readily available environmental/geotechnical reports, and/or other relevant documents pertaining to environmental conditions at the site. • Review federal, state, and local environmental database search results provided by Environmental Data Resources (EDR) for listings of known or suspected environmental G e o E n g i n e e r s 3 File No. 0186-407-00-1150/042998 problems at the site or nearby properties. The specific databases and minimum search distances reviewed included the following: U.S. Environmental Protection Agency Lists Minimum Search Distance National Priorities List (NPL) 1 mile Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS) 0.5 mile Resource Conservation and Recovery Act (RCRA), Corrective Action Report (CORRACTS) Facilities List 1 mile RCRA non-CORRACTS TSD Facilities List 0.5 mile RCRA Notifiers List, Generators and Transporters Site and Adjoining Properties Emergency Response Notification System (ERNS) Site State and Local Health Department Lists Minimum Search Distance Washington State Department of Ecology (Ecology) Department Lists Toxics Cleanup Program Confirmed and Suspected Contaminated Sites List (C&SCS) 0.5 miles Model Toxics Control Act (MTCA) Site Register 1 mile Ecology Registered Underground Storage Tank (UST) Sites List Site and Adjoining Property Ecology Leaking UST (LUST) Sites List 0.5 mile Solid Waste Disposal Facility 0.5 mile • Review regulatory agency files regarding listed sites of potential environmental concern relative to the site. • Identify key persons with specific knowledge of past and present site use and request that they meet a GeoEngineers' representative on-site for an interview during the site reconnaissance. Interview others familiar with past and present uses of the site and its vicinity as necessary. • Interview a representative of the local fire department, health department, and/or Ecology regarding the history of the site and surrounding properties relative to the likely presence of hazardous substances. • Review historical aerial photographs, fire insurance maps, city directories, tax assessor records, other historical maps and building department records, as available and appropriate, to identify past development history on the subject site and adjacent properties relative to the possible use, generation, storage, release or disposal of hazardous substances. We attempted to identify uses of the site from the present to the time that records show no apparent development of the site. However, we did not obtain historical information regarding on site activities prior to the late 1800's, at which time coal mining activities were being conducted on a portion of the site. GeoEngineers 4 File No. 0186-407-00-1150/042998 • Review current United States Geological Survey (USGS) topographic maps to identify the physiographic setting of the site. • Identify the sources of potable water for the site; the type of heating systems for site structures; and the type of sewage disposal at the site. • Provide a statement on the local geologic, soil and ground water conditions based on our general experience and sources such as geologic maps and soil surveys. • Conduct a visual reconnaissance of the site and adjacent properties to identify any visible evidence of possible contamination and potential sources of contamination. 2.2 PHASE II 1. Obtain 10 concrete surface samples (C-1, C-2 and C-4 through C-11) from selected transformer storage areas at the site. A concrete sample designated as C-3 was not obtained during the study. 2. Submit the concrete samples for chemical analysis of polychlorinated biphenyls (PCBs) by U.S. Environmental Protection Agency (EPA) Method 8081. 3. Obtain soil samples from 38 shallow direct-push borings (B-1 through B-38), nine shallow hand auger borings (B-39 through B-47), five test pit excavations (TP-1 through TP-5) and seven monitoring well borings (GMW-1 through GMW-7) at approximately 1- to 2-foot depth intervals. The explorations were completed to depths of approximately 3.0 to 12.0 feet beneath the ground surface. GMW-7 was completed off-site in Talbot Road, immediately downgradient of the southern portion of the property. 4. Obtain two sediment samples (S-1 and S-2) from a small storm water pond located in the eastern portion of the site; six sediment samples (S-3 through S-8) from inside selected stormwater catch basins on site; and two composite samples (GC-1 and GC-2) of coal mine tailings stockpiled in the eastern portion of the site. 5. Field screen the soil samples for possible petroleum hydrocarbon contamination. 6. Construct 2-inch-diameter monitoring wells in GMW-1 through GMW-7. 7. Survey the well casing elevations relative to an assumed site datum and measure the depth to ground water in each monitoring well on-site. 8. Obtain ground water samples from an existing monitoring well (MW-10), eight direct-push borings (B-30 and B-37) and GMW-1 through GMW-7. 9. Submit selected concrete, soil, sediment, coal mine tailings and ground water samples for one or more of the following chemical analyses: a. Diesel- and heavy oil-range hydrocarbons by Washington State Department of Ecology (Ecology) Method NWTPH-D extended. Samples B-1-3.0, B-32-0.5 and GMW-4-6.0 also were analyzed for volatile petroleum hydrocarbon (VPH) fractions; benzene, ethylbenzene, toluene and xylenes (BETX) and/or extractable petroleum hydrocarbon (EPH) fractions by Ecology's Interim Interpretive and Policy Statement, Cleanup of Total Petroleum Hydrocarbons (Interim TPH Policy) methods.

Semivolatile organic compound (SVOCs) by EPA Method 8270 10. Calculate site-specific Model Toxics Control Act (MTCA) Method B cleanup levels for petroleum hydrocarbons detected in the soil samples using Interim TPH Policy methods. 11. Evaluate the analytical results relative to current environmental regulations. Our scope of services did not include an environmental compliance audit, asbestos survey, lead-based paint survey, an evaluation of the potential presence of PCBs in light ballasts, or urea-formaldehyde insulation in on-site structures. Prezant Associates completed an inventory of asbestos, lead-base paint, and PCB in light ballasts in the on-site Stores and Service Center buildings. The results of the Prezant Associates studies are presented in written reports dated July and August 1995. The Prezant Associates reports were provided to GeoEngineers and are on file at PSE's Seattle office. 3.0 INVOLVED PARTIES The site currently is owned and operated by PSE. We understand that PSE is planning to sell the site through its wholly owned subsidiary, Puget Western Inc. 4.0 PREVIOUS ENVIRONMENTAL/GEOTECHNICAL INVESTIGATIONS GeoEngineers has provided environmental consulting services related to the subject site since 1987. Written reports summarizing the results of our previous site studies are on file with Ecology and include the following: • "Final Report - Ground Water Quality Testing, Underground Transformer Oil Tank, Service Center, Renton, Washington" -January 15, 1988. • "Final Report - Tank Removal and Soil Excavation, Underground Transformer Oil, Tank Service Center, Renton, Washington" - March 3, 1988. • "Report of Geotechnical Services, Subsurface Contamination Study, Former Renton Transportation Center, Renton, Washington" -July 26, 1988. • "Report of Remedial Action, Underground Storage Tank Removal, Renton Service Center, Renton, Washington" - December 15, 1989. • "Supplemental Report- GeoEnvironmental Services, Off-site Subsurface Contamination Study, General Stores Building, Renton Service Center, Renton, Washington" - November 29, 1990. • "Supplemental Report - GeoEnvironmental Services, Subsurface Contamination Study and Ground Water Monitoring Program, General Stores Building, Renton Service Center, Renton, Washington" - December 18, 1990. • "Report of Geotechnical Services, UST Removal and Subsurface Contamination Study, Stores Building, Renton Service Center, Renton, Washington" -January 17, 1990.

In addition to the studies described above, GeoEngineers conducted research in 1995 to evaluate historical site use. The results of that research are on file at PSE and were used to supplement the site history research (Section 8.0) for the Phase I portion of this study. 5.0 ENVIRONMENTAL SETTING Our knowledge of the general physiographic setting, geology, and ground water occurrence in the site vicinity is based on our review of the United States Geological Survey (USGS) Renton Quadrangle Topographical Map, dated 1949 (photo revised 1973); the EDR report; USGS Geologic Quadrangle Map of the Renton Quadrangle, King County, Washington, dated 1965; the results of our previous site studies and our general experience in the area. 5.1 REGIONAL PHYSIOGRAPHIC CONDITIONS The site is located in the northeast quarter of Section 19, the southwest quarter of Section 17 and the northwest quarter of Section 20, all lying within Township 23 North, Range 5 East, Willamette Meridian. The surface elevation of the site is approximately 40 feet above mean sea level. The subject site is located approximately 1/2 mile south of Cedar River and approximately 2 miles south of Lake Washington. 5.2 SOIL AND GEOLOGIC CONDITIONS The site vicinity is underlain by widespread or discontinuous artificial fill according to the geologic map we reviewed. Subsurface exploration performed by GeoEngineers at the site during previous studies encountered fill generally consisting of gravel, silty sand, silt and/or coal mine tailings to depths of up to 14 feet beneath the site surface. Native sand and silt units underlie the fill. 5.3 GROUND WATER CONDITIONS GeoEngineers constructed 33 monitoring wells in and around the northern portion of the Stores building during our previous studies. The locations of the monitoring wells previously installed at the site are shown in our previous reports. Additionally, GeoEngineers constructed four monitoring wells in the vicinity of a former transformer oil UST located south of the Stores building. Ground water generally was encountered at depths of approximately 5 to 8 feet beneath the site surface in these areas. The general direction of shallow ground water flow beneath the site is toward the west based on water level measurements. Most of the wells completed during our previous studies were removed during subsequent remedial excavation GeoEngineers 7 File No. 0186-407-00-1150/042998 activities or abandoned in place. However, monitoring wells MW-4, MW-8, MW-10 and MW-20, located near the north/northwest corner of the Stores building, remain intact. 6.0 GENERAL SITE CHARACTERISTICS 6.1 LOCATION AND LEGAL DESCRIPTION The site is located at 620 South Grady Way in Renton, Washington. The legal description of the site is presented in Appendix A. 6.2 SITE RECONNAISSANCE OBSERVATIONS Representatives of GeoEngineers performed a visual reconnaissance of the site on October 7, 1997. Subsequent site reconnaissance was conducted on December 17, 18 and 22, 1997 and February 18, 19, 20, 23 and 26, 1998 during Phase II tasks associated with this study. Primary site access is from South Grady Way. The approximate locations of the features discussed in this section are shown in Figure 2. Photographs of the site were taken to document observations made during our reconnaissance on October 7, 1997. Selected photographs of the site are presented in Figures 3a and 3b. Site features of potential environmental significance are discussed below. 6.2.1 Site Improvements The site consists of approximately 20.5 acres and is occupied by three buildings: the Stores building, the Service Center building, and the Division Office building. The Stores building serves as a warehouse and transformer storage and repair shop. The Service Center building is used as office space and for equipment/supply storage. The Division Office building is no longer occupied. It is currently used to store office furniture and equipment. Yard and dock areas south, west and east of the buildings currently are being used for transformer storage. A loading bay area located immediately west of the Service Center building currently is used to store PCB containing transformers that have leaked. The leaking transformers are stored in secure basins designed to contain their oil. A portion of the transformer storage yard previously was used to store power poles treated with preservative. A security fence surrounds the area in which the Stores building, Service Center building and transformer/former pole storage yard, and associated parking are located. A fuel service island and two registered 10,000 gallon fuel (gasoline and diesel) USTs, installed in 1989, are located between the Service Center building and the Stores building. A 2,000 gallon heating oil UST is located immediately east of the Stores building. Eight other fuel and oil USTs were removed from the site between 1987 and 1990 as described in our March 3, 1988, December 15, 1989, January 17, 1990 and February 7, 1991 reports. The majority of the area within the fence is paved with asphaltic concrete. The southern portions of the transformer/former pole storage yard are surfaced with gravel. The site areas south and east of the security fence are undeveloped. G e o E n g i n e e r s 8 File No. 0186-407-00-1150/042998 6.2.2 Pits, Ponds and Lagoons No pits or lagoons were observed on the site. A "marshy area" is located south of the site's security fence. Additionally, a small storm water pond is located in the eastern portion of the property (Figure 2). The pond appears to catch surface water runoff at the base of a hill that slopes up to the adjacent Benson Road South. We did not observe sheens or other physical evidence of contamination by hazardous substances at the pond location. 6.2.3 Site Drainage Surface drainage primarily is directed toward numerous catch basins on the site. Additionally, water from the previously mentioned pond flows into a drainage ditch (concrete-lined) located adjacent to the fence in the southern portion of the site. Water from the drainage ditch and the catch basins flows into the local storm water system at the southern portion of the site. A utility map, including the general layout of the site's storm water drainage system, is shown in Figure 4. 6.2.4 Stressed Vegetation, Stained Soil or Pavement Stressed vegetation, attributed to hazardous substances, was not observed on-site. A dark stain was observed on the concrete surface of the loading bay immediately west of the Service Center building. The cause of the stain is unknown. Other dark stains were observed on the pavement surface in areas where vehicles have been parked. These stains generally are less than 3 feet in diameter and, in our opinion, appear to have been caused by periodic low volume dripping of oil or grease from parked cars. Other significant stains were not observed on the site surface. 6.2.5 Water Wells, Sumps and Drains We observed four monitoring well monuments (MW-4, MW-8, MW-10 and MW-20) which were installed during previous GeoEngineers studies of the Stores building and its vicinity. Additionally, six new monitoring wells (GMW-1 through GMW-6) were constructed on-site during the Phase II portion of this study (Section 9.4). The Stores building contains a sump for condensation water located in the northwest corner of the heating system's boiler room. An "oil water separator", an "oil interceptor" and two "oil trap vaults" also were observed on-site (Figure 2). Additionally, the site contains numerous catch basins for surface water drainage as described in Section 6.2.3. Other evidence of water wells, sumps or drains was not observed on site. 6.2.6 Areas of Standing Water or other Liquids Areas of standing water or other liquids were not observed on the site with the exception of the small storm water pond described in Section 6.2.2. GeoEngineers 9 File No. 0186-407-00-1150/042998 6.2.7 Waste Generation and Disposal Unconfined refuse and/or debris was not observed on the site. PSE representatives we interviewed indicated that PCBs are removed from waste water stored in an AST (Section 6.2.8) located on the Service Center building loading dock and that the treated water is subsequently discharged into the metro sewer system in accordance with a discharge permit. Stockpiles of coal mine tailings are present between Main Avenue South/Benson Road South and the fence that borders the eastern portion of the storage yard. These stockpiles generally are densely vegetated with blackberry bushes. 6.2.8 Storage Tanks and Containers Three USTs are located on site: one 10,000-gallon diesel fuel UST and one 10,000-gallon unleaded gasoline UST, installed in 1989, and one 2,000-gallon heating oil UST. The USTs are located between the Stores building and the Service Center building near the north end of the fenced area. Two storage tanks containing up to 119 gallons of propane were observed on the site. Additionally, we observed the 3,700-gallon AST that contains waste water located in the Service Center loading dock. One storage shed ("RCRA shed"), used to contain batteries, was observed south of the Stores building. We observed 11 containers used to store leaking PCB-containing transformers located in the Service Center Bay area. We also observed approximately one hundred and fifty 55-gallon drums on site during our October 7, 1998 reconnaissance. The approximate drum storage locations observed on October 7, 1997 are shown in Figure 2. Labels on the drums identified the contents as waste soil, oil and other liquids. PCB-containing materials were present in some of the drums. Other drums observed on-site were labeled "non-hazardous." Based on our observations during subsequent site visits and our interviews with PSE representatives, it is apparent that the content and number of drums stored on the site changes regularly. The drums we observed appeared to be in good condition. We did not observe evidence of leakage from the drums. 6.2.9 Indications of PCBs, Transformers and Utilities The Stores building is utilized, in part, as a transformer repair shop. Some of the transformers contain PCBs. PCB transformers, identified as having leaked, currently are stored in 55-gallon drums which are stored in large plastic containers in the area designated for storage of leaking transformers; this storage area is located west of the Service Center building. PCB-containing materials and PCB storage areas at the site are managed in accordance with federal Toxic Substances Control Act (TSCA) regulations and PSEs PCB-handling program. Numerous non-PCB containing transformers also are stored on the site. The site contains one operating transformer in a vault located immediately east of the Service Center building. The transformer vault was secured in such a manner that access was G e o E n g i n e e r s 10 File No. 0186-407-00-1150/042998 not practical during our site reconnaissance. PSE representatives we spoke with indicated that they are unaware of any releases of insulating oil from the transformer in the vault. The City of Renton supplies the site with water and sewage service. The Stores building is heated with a boiler fueled by heating oil. The Service Center building and the vacated Division office building are heated by electricity. 6.2.10 Radon We contacted the Washington State Department of Health (DOH) regarding the potential for radon gas in Western Washington. According to DOH, the potential for radon gas in the Puget Sound region is very low. It is estimated to that only one percent of houses in the Puget Sound region have radon gas concentrations exceeding 4 picocuries per liter (pCi/L). The national average for radon gas concentrations in buildings and structures is 4 pCi/L. According to DOH, radon gas is typically not a problem in larger buildings that have forced air or better ventilation. We also contacted the EPA Radiation Protection Program. EPA representatives concur with the opinion of DOH regarding the radon gas potential in the Puget Sound Region. Additionally, EPA suggested that radon gas concentrations in the Puget Sound region are low for the following reasons: (1) a low uranium content in soils (radon gas is a decay product of uranium 238), (2) moist soil conditions (moisture inhibits radon movement), and (3) a high degree of fines in the soil (lower permeability soils inhibit radon gas movement). Based on our conversations with personnel from the EPA and DOH, it is our opinion that the potential for radon gas at concentrations in excess of 4 pCi/L at the site is low. 6.2.11 Other Conditions of Concern We did not observe other conditions of concern regarding the potential for site soil and/or ground water contamination by hazardous substances. 6.3 ADJACENT PROPERTY AND VICINITY OBSERVATIONS Residential, commercial and undeveloped properties border the subject site to the north. A parking structure is located immediately northeast of the site. The eastern and southern portions of the site are bordered by Main Avenue South and Benson Road South, respectively. Interstate Highway 405 is on the opposite side of Main Avenue South. The adjacent properties to the south and west are occupied by commercial and office buildings that are separated from the site by Benson Road South and Talbot Road South, respectively. An AM/PM ARCO service station is located immediately west of the site, at the intersection between Talbot Road South and South Grady Way. We did not observe any evidence of past or present use, storage, generation, release, or disposal of hazardous substances on adjacent properties with the exception of fuel storage at the nearby service station, located downgradient (west) of the site. G e o E n g i n e e r • 11 File No. 0186-407.00-1150/042998 7.0 ENVIRONMENTAL RECORDS REVIEW GeoEngineers reviewed the results of an environmental records (regulatory lists) search for those facilities that currently or previously have occupied properties within an ASTM-specified distance from the subject site. The information reviewed was compiled by EDR. The EDR report is included in Appendix B. The report includes details regarding the listed facilities identified and maps showing the locations of the listed facilities relative to the subject site. The subject site is included on the registered UST and the leaking UST lists according to the EDR report we reviewed. The UST site number for the Grady Way Complex is 8532. The site is listed for the current and former USTs described in Sections 6.2.8 and 8.3 of this report. The site is included on the leaking UST list because of soil conditions encountered around the site's former USTs (now removed). These areas were successfully remediated between 1987 and 1990 as documented in our prior reports. Those listed off-site facilities found within the specified distance from the subject site were evaluated for potential impact to the subject site. The listed facilities identified either are located a significant distance (1/4 mile or greater) from the site or are located in an inferred down- or cross-gradient location relative to the site, based on our review. In our opinion, the potential for subject site contamination originating from one or more of the listed facilities identified in the EDR report is low. Therefore, we did not review Ecology files for the listed facilities with the exception of the file for the service station located immediately west (downgradient) of the site at 509 S. Grady Way. We reviewed the file for this service station because of its proximity to the subject site. Documents in the Ecology file do not indicate that contamination from the service station facility has impacted the subject site. Additionally, there were no indications that contaminants from the subject site have migrated onto the service station property. 8.0 SITE HISTORY Our understanding of site history is based on the results of our prior site studies; review of Sanborn fire insurance maps dated 1904, 1909, 1927 and 1929; evaluation of aerial photographs dated 1936, 1946, 1960, 1968, 1974, 1977, 1980, 1985 and 1992; review of various PSE file materials including maps, building plans, spill reports and a spill prevention control and counter measure plan; and interviews with the following persons: • Larry Herwitz of PSE (08/14/95) • Manny Wilson of PSE (08/17/95) • Bob Banasky of PSE (08/17/95) • Lance Taylor PSE (08/17/95 and 11/19/97) • Renato Pagalilauan of PSE (08/17/95) • Kevin Case of PSE (08/17/95) • Kate Oehler of PSE (08/17/95) GeoEngineers 12 File No. 0186-407-00-1150/042998 • Bill Carey of PSE (08/17/95) • Jerry McNeilly of PSE (08/17/95) • Curtis Dahlgren of Ecology (08/25/95) • Dave Yasuda of PSE (10/02/97) • Reid O. Kinne of PSE (10/07/97) • Julie, Renton Fire Department (11/04/97) • Brenda Campbell of PSE (11/12/97) • Patty McClements of PSE (11/17/97) • Allan Miller of PSE (2/20/98) A summary of historical site use based on these sources is presented below. 8.1 GENERAL • PSE purchased most of the site and adjacent property west of the site, across Talbot Road South around 1903. A portion of the adjacent property west of the site was developed as an electrical substation in the early 1940s. • An entrance to a coal mine was located in the eastern portion of the site in the late 1800s and early 1900s. Large piles of coal mine tailings covered portions of the site at that time. A railroad spur was located in the eastern portion of the site. It appears that PSE owned a part or all of the coal mine operation, based on Sanborn maps and PSE's real estate files. Current site facilities were constructed on fill consisting of the coal mine tailings. The nature of the on-site fill is discussed in Section 9.2. • The site was used as a pasture for a farm after the coal mine stopped operation. • The Stores building was constructed in 1951 and the Service Center and Division Office buildings were constructed in 1956, according to tax records. The Division Office building is no longer in use. • PSE's current and past activities performed at the site include (1) warehousing a stock of supplies for other PSE facilities, (2) storage and maintenance of transformers, and (3) fueling and maintenance of fleet vehicles. • Some of the materials warehoused at the site include PCBs at concentrations greater than 500 parts per million (ppm). • Vehicle maintenance and repair took place in the northern (garage) portion of the Stores building until approximately 1991. Hydraulic lifts and USTs in that area were removed. • A vegetated "marshy" area is located south of the site security fence. • Some of the PSE personnel we interviewed speculated that transformers may be buried beneath portions of the southern half of the site. Our research did not identify other historical information suggesting that transformers were buried on-site. Test pits TP-1 through TP-5, monitoring well borings GMW-3 through GMW-6 and hand auger borings B-40 through B-47 (Figure 5), were completed during Phase II of this study in G e o E n g i n e e r . 13 File No. 0186-407-00-1150/042998 areas identified as possible transformer burial locations based on our interviews. Transformers were not encountered in our subsurface explorations. • The fire department indicated that they have no records of historical hazardous materials "incidents" (spills or fires) at the subject site. We did not identify any historical adjacent property use that represents a significant potential source of contamination by hazardous substances on the subject site. 8.2 TRANSFORMER REPAIR SHOP AND TRANSFORMER/POLE STORAGE YARD • The transformer repair shop has been in use at the site for at least 25 years and is located in the southern portion of the Stores building. • Two fiberglass ASTs that contained acid and an unidentified "cleaner" were located in the transformer repair shop and were used to clean transformers. Transformers were submerged in the tanks to remove paint. The tanks were taken out of service around 1986. We obtained a ground water sample from boring B-32, located immediately adjacent to the transformer repair shop during Phase II of this study to evaluate the potential presence of solvents (HVOCs) near these former tanks. HVOCs of regulatory significance were not detected in the ground water sample obtained from B-32 (Section 9.4). • Transformers have been stored on the site for at least 35 years. PSE implemented a program approximately 12 years ago for documenting spills and subsequent cleanups that occur at the Grady Way site. Transformer storage primarily has occurred in the areas south and west of the Stores building and the area south and east of the Service Center. We understand that PCB-containing transformers have been stored and managed separately from non-PCB transformers for at least 12 years. • PCB-containing transformers currently are stored on the concrete storage docks adjacent to the transformer repair shop and the Service Center building. We understand that some of the PCB-containing transformers may have been stored in the transformer storage yard prior to 1980. • PSE's Spill Prevention Control and Countermeasure (SPCC) plan identified three areas of the site as current "PCB Storage Areas." These locations are shown in Figure 2. • A transformer oil AST was located on the storage dock at the southern end of the stores building. According to Lance Taylor, this AST was removed approximately three years ago. • Power poles treated with creosote were stored on the site in the area south of the Stores building until approximately 1990. We understand that the application of chemical preservatives to the poles did not take place at the site. • e o E n g i n e e r • 14 File No. 0186-407-00-1150/042998 8.3 PREVIOUS REMEDIAL ACTIONS • GeoEngineers monitored the excavation and removal of approximately 650 cubic yards of petroleum-contaminated soil from the vicinity of a waste transformer (insulating/mineral) oil UST in 1987. The contaminated soil and the UST were transported off-site for permitted disposal. The waste transformer oil UST was located south of the transformer repair shop in the transformer storage yard. The UST was connected to a vault in the transformer repair shop by underground piping. The approximate extent of this remedial excavation is shown in Figure 2. • GeoEngineers consulted Ecology and established a remedial action level (RAL) for total petroleum hydrocarbons of 300 milligrams per kilogram (mg/kg) during remediation of soil contamination near the waste transformer oil UST to account for the effect of the coal tailings on TPH concentrations detected by chemical analysis. • GeoEngineers monitored the removal of seven additional USTs from the vicinity of the Service Center and Stores buildings in 1989 and 1990. The approximate locations of these former USTs and associated remedial excavations are shown in Figure 2. • Approximately 3,100 cubic yards of hydraulic fluid-contaminated soil were removed from the former garage area located in the northern portion of the Stores building in 1990. The hydraulic fluid-contaminated soil was transported to a permitted landfill for disposal. The garage, including three hydraulic lifts, was taken out of service in 1990. • The USTs removed in 1989 and 1990 were replaced with a 10,000-gallon gasoline UST, a 10,000-gallon diesel UST and a fuel island located east of the former garage area. We understand that the new USTs are double-walled and contain interstitial leak detection devices. There have been no reported leaks from the new USTs according to PSE and the Ecology records we reviewed. • Field screening and chemical analytical results for soil samples obtained from the final limits of the prior remedial excavations indicate that soil containing residual petroleum hydrocarbon concentrations exceeding applicable MTCA cleanup levels were successfully removed from the former UST and hydraulic lift areas. • A heating oil UST is located east of the Stores building. We understand that the original heating oil UST, installed in approximately 1950 at the site, was replaced with the current heating oil UST in the same location. We further understand that visual observations during the heating oil UST replacement indicated that minor amounts of petroleum-related soil contamination may exist in the vicinity of the UST. Chemical analysis of a ground water sample obtained from boring B-37, located immediately downgradient of the UST, did not detect petroleum hydrocarbons (Section 9.4). 8.4 ENVIRONMENTAL LIENS During the course of our research, we did not find that environmental liens had been filed against the site. GeoEngineers 15 File No, 0186407-00-1150/042998 9.0 PHASE II ENVIRONMENTAL SITE ASSESSMENT 9.1 CONCRETE SAMPLES AND ANALYSIS A representative of GeoEngineers obtained ten concrete samples (C-1, C-2 and C-4 through C-11) from various transformer storage locations at the site for PCB analysis on December 18 and 22, 1997. The concrete samples were obtained from the surface of the storage/loading docks where transformers have been stored. The approximate concrete sample locations are shown on Figure 5. PCBs were detected in samples C-2, C-4, C-5, C-7, C-8, C-9 and C-11 at concentrations ranging from 75.9 to 1,050 micrograms per kilogram (µg/kg). The concrete analytical results are presented in Table 1. Concrete sampling methods are described in Appendix C. Laboratory reports for the concrete samples are presented in Appendix D. 9.2 SOIL SAMPLING AND ANALYSIS Soil conditions in the eastern and southern portions of the site were evaluated by obtaining discrete soil samples from 38 shallow direct-push borings (B-1 through B-38), nine shallow hand auger borings (B-39 through B-47), five test pit excavations (TP-1 through TP-5), and seven monitoring well borings (GMW-1 through GMW-7). Additionally, two grab samples were obtained from the coal mine tailings stockpiles (GC-1 and GC-2) at approximately 1- to 2-foot depth intervals. The explorations were completed between December 18, 1997 and February 23, 1998 to depths of approximately 3.0 to 12.0 feet beneath the ground surface (bgs) at locations of suspected subsurface contamination based on the results of the Phase I ESA. GMW-7 was completed off-site in Talbot Road immediately downgradient of the southern portion of the property (ground water flow direction is discussed in Section 9.4). The approximate locations of the explorations completed for this study are shown in Figure 5. Field sampling methods and soil logs are presented in Appendix C. Geologic cross sections depicting the soil conditions encountered in our explorations are presented in Figures 6a and 6b. The soil samples were classified and field screened for evidence of potential petroleum hydrocarbon contamination. The explorations generally encountered loose to dense fill consisting of near surface sand or gravel underlain by coal mine tailings. The coal mine tailings consist of black silt and sand with varying amounts of coal fragments. The tailings consist primarily of coal fragments in some portions of the site. Deeper explorations generally encountered native silt or sand approximately 10 to 12 feet bgs. Field screening evidence of petroleum hydrocarbons was not detected in the soil samples obtained from,the explorations, with the exception of samples GMW-7-8.0 and GMW-7-11.0. Seventy-three soil samples were submitted to North Creek Analytical Laboratory of Bothell, Washington for one or more of the chemical analyses described in Section 2.2. Soil samples were selected for analysis based on their location relative to suspected sources of GeoEngineers 16 File No. 0186-407-00-1150/042998 contamination and/or the ground water table. Many of the soil samples obtained from depths of approximately 0.5 foot of the site surface were submitted for chemical analysis to evaluate the effects of surface spills from transformers and/or impacts from the wood preservative present on the power poles that were formerly stored on-site. Selected soil samples from approximately 2.0 to 3.0 feet bgs were submitted for analysis to evaluate the vertical extent of residual contamination detected in shallower samples. The chemical analytical results are described below. 9.2.1 Petroleum Hydrocarbons Diesel- and heavy oil-range petroleum hydrocarbons were detected in most of the soil samples submitted for chemical analysis. Our Phase I ESA research and chemical analyses indicate that periodic transformer (insulating/mineral) oil leaks from electrical transformers stored in the southern and eastern portions of site during the past 40 years have resulted in residual concentrations of petroleum hydrocarbons in soil. Transformer oil elutes in the diesel- and heavy oil-range when analyzed by gas chromatography. The residual transformer oil- related hydrocarbons in soil at the site were quantified either as transformer oil and/or undifferentiated diesel- and heavy oil-range hydrocarbons by the laboratory. Chemical analysis also detected hydraulic/lube oil-range hydrocarbons in some of the soil samples. A specific source of these hydraulic/lube oil-range hydrocarbons was not identified by our study. Site specific MTCA Method B cleanup levels were calculated using Ecology's Interim TPH Policy for the petroleum hydrocarbons detected. MTCA Method B cleanup level calculations are summarized in Appendix E. Petroleum hydrocarbon concentrations in all the soil samples submitted for analysis were less than the MTCA Method B cleanup levels calculated for the site. The MTCA Method B cleanup levels calculated for the specific hydrocarbon ranges identified were 3,965 mg/kg for transformer oil-related hydrocarbons quantified as diesel- and heavy oil-range hydrocarbons, 3,971 mg/kg for hydrocarbons specifically quantified as transformer oil, and 3,432 mg/kg for hydraulic/lube oil-range hydrocarbons. Petroleum hydrocarbon concentrations detected in soil on-site ranged from 23.4 to 2,120 mg/kg. Petroleum hydrocarbon concentrations in the soil samples tested generally decreased significantly within approximately 3 feet of the site surface. Chemical analysis detected diesel- and heavy oil-range hydrocarbons at concentrations of 3,890 mg/kg and 2,390 mg/kg respectively in the soil sample obtained from GMW-7 approximately 8.0 feet beneath Talbot Road immediately west of the site. Numerous utility trenches are located beneath Talbot road. Utility trenches can act as a conduit for migration of petroleum hydrocarbons relatively long distances from their source. The source of the petroleum hydrocarbons in GMW-7 was not identified by our study. Soil chemical analytical results for petroleum hydrocarbons at the site are presented in Table 2. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. G e o E n g i n e e r e 17 File No. 0186-407-00-1150/042998 9.2.2 PCBs PCBs either were not detected or were detected at concentrations less than the MTCA Method A cleanup level (1 mg/kg) in the 53 soil samples submitted for PCB analysis with the exception of soil samples B-7 (1.33 mg/kg), B-34 (1.62 mg/kg) and TP-5 (1.85 mg/kg). These three samples were obtained from approximately 0.5, 0.5 and 4.0 bgs, respectively. Soil chemical analytical results for PCBs are presented in Table 3. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. 9.2.3 SVOCs SVOCs including pentachlorophenol (PCP) and carcinogenic polynuclear aromatic hydrocarbons (cPAHs) either were not detected or were detected at concentrations less than applicable MTCA cleanup levels (8.33 mg/kg PCP and 1 mg/kg cPAHs) with the exception of soil samples B-19 (1.70 mg/kg cPAHs), B-23 (2.46 mg/kg cPAHs) and B-29 (2.05 mg/kg cPAHs). These samples were obtained from a depth of approximately 0.5 foot bgs. Soil chemical analytical results for SVOCs are presented in Table 3 Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. 9.3 SEDIMENT SAMPLES A representative of GeoEngineers obtained two sediment samples (S-1 and S-2) from the storm water pond and six discrete sediment samples (S-3 through S-8) from selected catch basins on February 18, 1998 at the approximate locations shown in Figure 5. Petroleum hydrocarbons and PCBs either were not detected in the sediment samples or were detected at concentrations less than MTCA soil cleanup levels. Sediment samples S-4 and S-5 contained cPAH concentrations (2.87 and 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) for cPAHs. Freshwater sediment cleanup levels have not been established under MTCA. Sediment chemical analytical results are presented in Tables 2 and 3. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D. We estimate that the on-site catch basins contain less than two cubic yards (total) of sediment based on our observations. 9.4 GROUND WATER Ground water conditions beneath the site were explored by obtaining ground water samples from eight of the direct-push borings (B-30 through B-37) and seven monitoring wells (GMW-1 through GMW-7) installed during this phase of work. The approximate boring and well locations are shown in Figures 5 and 7. Well construction details and ground water monitoring methods are presented in Appendix C. GeoEngineers 18 File No. 0186-407-00-1150/042998 Water levels were measured in existing wells MW-4, MW-8, MW-10 and MW-20 on December 22, 1997 and in new and existing wells MW-4, MW-8, MW-10, MW-20 and GMW-1 through GMW-7 on February 26, 1998. Water levels at the time of our measurements ranged from 1.87 (GMW-3) to 7.84 (MW-8) feet bgs. The ground water table beneath the site was slightly higher in December 1997 than in February 1998 based on our measurements. Ground water depth measurements and calculated ground water table elevations are presented in Table 4. A ground water contour map based on our February 26 measurements is presented in Figure 7. Shallow ground water appears to flow in a westerly direction beneath the site, based on our February 26 measurements. Ground water samples from selected borings (B-30 through B-37) and MW-10 were obtained on December 18 and 22, 1997 for the chemical analyses described in Section 2.2. Diesel- and heavy oil-range hydrocarbons were detected in ground water samples B-30, B-31, B-34 and B-36 at concentrations ranging from 1.63 to 3.4 milligrams per liter (mg/I), which exceeds the MTCA Method A cleanup level (1 mg/I). Additionally, PCBs and cPAHs were detected in ground water sample B-34 at concentrations [(0.260 and 0.821 micrograms per liter (µg/1), respectively] exceeding the MTCA Method A cleanup level (0.1 µg/1) for these compounds. PCBs also were detected at a concentration (2.82 µg/1) exceeding the MTCA Method A cleanup level in the ground water sample obtained from B-36. Methylene chloride was detected in the ground water sample obtained from boring B-32. The methylene chloride in the B-32 sample was identified as a laboratory contaminant by the laboratory. Other HVOCs were not detected in the ground water sample obtained from B-32. Other analytes were not detected at concentrations exceeding MTCA cleanup levels in the ground water samples obtained from the borings and MW-10. It is our experience that chemical analytical results from direct-push borings should be used only as a screening tool because they generally are biased high. Therefore, monitoring wells GMW-1, GMW-4, and GMW-6 were constructed to further evaluate ground water conditions in the vicinity of B-30, B-31, B-34 and B-36. Ground water samples were obtained from GMW-1 through GMW-6 (on-site) and GMW-7 (off-site) on February 20, 1998 and submitted for the chemical analyses described in Section 2.2. Diesel- and heavy oil-range hydrocarbons were detected in GMW-2 at concentrations of 1.37 and 12.27 mg/I, respectively, which exceed the MTCA Method A cleanup level of 1.0 mg/1. GMW-7 is located downgradient of the site, immediately adjacent to numerous utility trenches beneath Talbot Road. Additionally, PCBs were detected in GMW-4 at a concentration (1.17 µg/1) exceeding the MTCA Method A cleanup level (0.1 µg/1). Other analytes either were not detected or were detected at a concentration less than MTCA cleanup levels in the ground water samples submitted for analysis. Ground water chemical analytical results are presented in Table 5. Our review of laboratory QA/QC (quality assurance/quality control) and the laboratory reports are presented in Appendix D.

The wells identified are presented in Table 8. The approximate well locations relative to the subject site are presented in Figure 8. The closest water supply wells in Ecology's records are located approximately M-mile northeast (upgradient/cross gradient) of the site. 10.0 CONCLUSIONS GeoEngineers has performed a Phase I/II ESA of PSE's Grady Way Complex property located at 620 South Grady Way in Renton, Washington. The Phase I ESA portion of our study was conducted in general accordance with the scope and limitations of ASTM E 1527-97. Based on the ESA results, soil and ground water contamination of regulatory significance appears to be limited to portions of the southern third of the site as shown in Figure 9. The results of our studies indicate that the potential for existing soil and/or ground water contamination of regulatory significance in the northern portion of the site is low. The results of our ESA indicate that soil and ground water contamination is present at concentrations of regulatory significance at the following specific locations in the southern portion of the site (Figure 9): • Diesel- and heavy oil-range hydrocarbons were detected in a ground water sample obtained from GMW-2 at a concentration (1.37 mg/I) slightly exceeding the MTCA Method A cleanup level (1 mg/I). • PCBs were detected at concentrations (1.33 to 1.85 mg/kg) slightly exceeding the MTCA Method A cleanup level (1 mg/kg) in soil samples obtained from three locations (B-7 at 0.5 foot bgs, B-34 at 0.5 foot bgs and TP-5 at 4.0 feet bgs). • PCBs were detected at a concentration (1.17 µg/1) exceeding the MTCA Method A cleanup level (0.1 µg/1) in ground water obtained from GMW-4. • Carcinogenic PAHs (cPAHs) were detected at concentrations (1.70 to 2.46 mg/kg) exceeding the MTCA Method A cleanup level (1 mg/kg) in shallow (0.5 foot bgs) soil samples obtained from three locations (B-19, B-23 and B-29). • CPAHs were detected at concentrations (2.87 to 6.75 mg/kg) exceeding the MTCA Method A soil cleanup level (1 mg/kg) in two of the six sediment samples obtained from catch basins. Additional localized residual PCB and/or PAH concentrations exceeding applicable cleanup levels may be present immediately adjacent to portions of the on-site catch basins, stormwater conveyance pipes and/or buried transformers, if present. The extent of residual cPAH and/or PCB concentrations exceeding applicable cleanup levels in the vicinity of B-7, B-19, B-23, B-29, B-34 and TP-5 was not fully evaluated by our study. However, based on our experience with these compounds at other similar PSE sites and GeoEngineers 20 File No. 0186407-00-1150/042998 the soil and ground water analytical results, we expect that the areas of contaminant concentrations exceeding cleanup levels would be localized. Other soil samples obtained near the areas of PCB and cPAH cleanup level exceedances identified above did not contain concentrations of these compounds that exceed applicable cleanup levels. Our conceptual volume estimate of soil containing PCB and cPAH concentrations exceeding MTCA Method A cleanup levels in the southern portion of the site is 500 cubic yards. This estimate assumes that the PCB and/or cPAH concentrations of regulatory significance are limited to an area within approximately 20 feet of sample locations B-7, B-19, B-23, B-29, B-34 and TP-5-4. The actual volume may vary significantly from this conceptual estimate. Chemical analysis did not detect contaminant concentrations exceeding applicable cleanup levels in 73 of the 81 soil/sediment samples and four of the six on-site ground water samples submitted for chemical analysis. Diesel- and heavy oil-range hydrocarbons either were not detected or were detected at concentrations less than the Model Toxics Control Act (MTCA) Method A cleanup level (1 mg/I) in ground water samples obtained from the monitoring wells on-site with the exception of GMW-2. MTCA Method B cleanup levels were calculated in accordance with Ecology's Interim TPH Policy for direct contact and soil-to-ground water exposure pathways (Appendix E) using soil analytical data from the site. The MTCA Method B cleanup levels range from 3,432 mg/kg to 3,971 mg/kg for the various types of petroleum hydrocarbons present in soil at the site. Petroleum hydrocarbons were detected in soil at concentrations less than the most conservative MTCA Method B cleanup level (3,432 mg/kg) calculated for the site. The Interim TPH Policy does not specify an approach for evaluating the potential risk caused by hydrocarbon vapors, therefore the soil-to-air pathway was not specifically evaluated during this study. However, significant concentrations of volatile compounds typically are not associated with transformer oils and hydraulic/lube oils like those detected at the site. Furthermore, benzene was not identified as a contaminant on the site. Institutional controls could be implemented at the site to protect human health from hydrocarbon vapors if future regulatory policy requires specific mitigating measures for protection of human health through the soil-to-air pathway. Significant concentrations of diesel- and heavy oil-range petroleum hydrocarbons were detected in soil and ground water obtained from monitoring well/boring GMW-7 located in Talbot Road, immediately downgradient from the southern portion of the site. In our opinion the source for the petroleum-related soil and ground water contamination detected in GMW-7 is not likely located on the subject site because petroleum-related contamination of regulatory significance was not detected in the two on-site wells (GMW-5 and GMW-6) located closest to, and upgradient of, GMW-7. Our study did not identify evidence concerning the specific source of the petroleum hydrocarbons detected in GMW-7.
