' The UST was decommissioned and excavated by O'Sullivan Petroleum Equipment - Company (OPEC) of Seattle, Washington. Hazcon, Inc. (Hazcon) performed the UST Site Assessment for the project following Washington State Department of Ecology's ' (Ecology) Guidelines for Site Checks and Site Assessments for USTs. The objectives of this project included: Removing one 500 gallon diesel fuel UST and associated piping and pump island; ' + Determining concentrations of diesel total petroleum hydrocarbons (TPHs) in soil adjacent to and underlying the UST system and associated soil stockpile; ' + ,Comparing concentrations of diesel TPHs detected in soil, if any, to the applicable Washington State Model Toxics Control Act (MV7,A) Method A Soil Cleanup Guidelines (WAC 173-340) and Guidance for Remediation of Releases from USTs;. and ■ Inte retin' field and analytical -dat documenting field and UST removal activities, rP g Y � g ' making recommendations for additional site characterization (if any), and preparing this report (following Washington State Department of Ecology's Guidance for Site Checks and Site Assessment for USTs). Industrial Hygiene & Safety Sendces - Asbestos Survey & Design Senices ' Emironmental Senices - Laboratory Semces - T{ainiM Courses V Page Two Rental Marts ' Location - The -Rental Mart is located at 29805 Pacific Highway South, Federal Way, Washington, (Section 4, Township 21 North,'Range 4 East) (Figures 1 and 2). The subject -property lies approximately one mile southeast of Poverty Say and seen -tenths mile south of 288th Street, at an elevation of approximately 430 feet above sea level. The area immediately adjacent to the subject property is predominately used for residential or light commercial purposes. The subject property is operated by Rental Marts for equipment rental. The 500 gallon diesel fuel UST was located approximately 35 feet north of the west end of the Rental Mart facility (Figure 2). L Letter Report Organization, This letter report begins with a Summary of Findings for' this project. Fallowing the Summary of Findin'31gs is a discussion on project area geology and soil/groundwater'- conditions. Subsequent sections present other elements of Hazcon's UST Site Assessment investigation (UST history and decommissioning activities, excavation' descriptions; soil' sampling, laboratory analyses, findings, and conclusions). Figures and Tables accompanying this report follow the main text and are followed by the UST 30-Day Notice of Intent, UST Permanent CIosure, and UST Site Assessment Checklists (as filed with Ecology). Supporting technical appendices follow the UST Site Assessment Checklist. SUMMARY OF FINDINGS Diesel TPH concentrations detected in soil samples collected within the diesel fuel UST excavation ranged from non -detectable to 140 ppm (below MTCA •Method A Soil Cleanup Levels). The TPH concentration (as diesel and lubricating oil) for one representative sample collected from the soil stockpile was 4,90 ppm (above the MICA Cleanup LeveI). The soil stockpile classified as a Class III soil and was disposed of at the permitted Rabanco Landfill (by Rabanco) as a non -hazardous MTCA material. LOCAL GEOLOGY AND GROUNDWATER Local Geology The geology in the y'tciniiy of the subject property is dominated by Upper Pleistocene ground moraine deposits (Waldrdn, 1961) generally composed of thin ablation till overlying lodgment till (Mullineaux, 1965). Lodgement till is generally a compact, coherent, unsorted mixture of sand, silt, clay, and gravel; commonly termed .hardpan. Ablation till is similar, but less compact and coherent. Lodgement till is practically impermeable and relatively difficult to excavate and stable along steep exposures. Rental Marls/Federal way Hazcdn, Inc. . 1 1 Page Three Rental Marts ' Site Geology . Sail within the UST excavation generally consisted of dry gravely sands from the surface to a depth of 2 feet below ground surface (BGS), sandy fine gravel from 2 tv 3 feet BGS, and moist gravely sands from 3 feet to at least 8 feet BGS (Photo llAppendix A).- -Groundwater Groundwater was not encountered in the UST excavation pit. UST HISTORY The 500-gallon diesel fuel UST and pump island dispenser were located 35 feet north of ' the Rental Marts facility (Figure 2).- According to Rental Marts the UST and single pump island dispenser where installed in about 1970. According to records on -file with' the, Washington State DOE UST Section, this UST was installed before-1965 (personal. communication, Roger Nye). The UST was active until being decommissioned 4n May ' 21, 1993 (personal communication, Mike Muller, OPEC). The UST system stored diesel fuel #2 during it's tenure and was used to refuel Rental Mart's rental equipment. The UST system consisted of a single -wall steel tank and associated steel piping. The UST was not anchored nor was it equ* ipped with overfill or cathodic protection. The UST system check valve was•located at the pump island dispenser and consisted of suction -type ' piping. OPEC is unaware of any volumetric tank tightness tests performed on the UST. The UST was inerted and excavated by OPEC on June 25, 1993. Prior to excavation the UST was triple rinsed and inerted with CO2 under OPEC's supervision. OPEC removed ' the UST from the excavation using a tire mounted backhoe. The tank showed minimal signs of rust and corrosion (e.g., pock marks) (Photo 2). OPEC transported the UST to, Coastal Tank Inc. of Seattle, Washington for scrap metal (Appendix B). r EXCAVATION SITE DESCRIPTION " 1 The UST was oriented north -south. The removal of the UST; associated piping, ana the pump island dispenser (Photo 3) resulted in a single excavation pit (i.e., the pump island " ' and was located above the UST). OPEC excavated the UST system using a tire mounted backhoe. The UST system ' excavation pit was 13 feet by 8 feet in plan and had a depth of 8 feet BGS. Approximately 30 cubic yards of excavated soil was stockpiled adjacent to and west of the excavation pit (Figure 2). The soil stockpile was placed on and covered with visquene and bermed. The UST system excavation was surrounded with a chain Iink fence until site restoration. ' Rental-MarulFedera! Way Hazcon, Inc. Ll Page Four Rental Marts SOIL SAMPLING Soil samples were selected by a Hazcon geologist (registered site' assessor with the Washington "State Department of Ecology), based on visual and olfactory observations. Hazcon collected a total of eight discrete soil samples, from the UST excavation (five . samples) and associated soil stockpile (three samples) (Figure 2). The five samples collected. from, the UST excavation pit included four samples from the excavation pit sidewalls (samples SW1-6.0, SW2-6.5, SW3-6.5, and SW4-7.0)and one from the excavation pit floor (sample 131-8.0). Sidewall samples were collected between 6.0 feet and 7.0 feet BGS.' The excavation pit floor sample was collected -at 8.0 feet'BGS. Groundwater was not encountered the UST excavation pit. Soil samples from the UST excavation were collected using the backhoe to withdraw soil from the excavation pit. An aliquot of soil was then _removed from the center of the backhoe bucket using a stainless steel spoon and transferred to a preconditioned sterilized glass jar (soil sampling profocols,i Appendix C). Soil samples collected.from the soil stockpile were collected with a hand auger from the approximate soil stockpile center (samples STPI to STP3). Soil samples were placed in .an ice chest and transported to the analytical laboratory. Chain of custody procedures were followed for all samples. LABORATORY ANALYSES Soil samples were analyzed for parameters outlined in Ecology's Guidance for Site Checks and Site Assessments for USTs (their Table 6-1. Required and Recommended Analyses for Petroleum Substances). A total ?f five soil samples (two composite and three discrete soil samples) were analyzed for diesel TPHs by Friedman.and Bruya Laboratories, Inc: of Seattle, Washington. Samples SW1-6.0 and SW3-6.5, (collected from the east and south sidewall respectively) were composited together into one sample for analysis (samples were =idewall, ited together by the laboratory chemist). Samples SW2-6.5, SW4-7.0, and B1-8.0 north sidewall, pit floor, respectively} were analysed as discrete soil samples. Soil stockpile samples STPI,,STP2, and-STP3-were composited together into one sample for analysis. A full laboratory report and a quality assurance review of the laboratory results are given in Appendix D. , FINDINGS Composite sidewall sample SW1-6:0/SW3-6.5 had non -detectable diesel TPHs (Table 1). Discrete sidewall samples SW2-6.5 and SW4-7:0 had a diesel TPH concentrations of 80 ppm and 140 ppm, respectively. Soil sample SW4-7.0 was collected from a narrow zone of soil contamination restricted to the northwest corner of the UST excavation (Photo 1). This soil sample was selected with the intent of representing a worst case scenario of contaminated soil within this narrow band. Discrete sample 131-8.0 had a diesel TPH concentration of 20 ppm. Soil stockpile composite sample (STP1/STP2/STP3) had a TPH (as a mixture of diesel and lubricating oil) concentration of 490 ppm (see Table I/Appendix D). Rental Mars/Federal Way Hazcon, Inc. Page Five Rental Marta CONCLUSIONS All soil samples collected from within the UST excavation pit had diesel •TPH concentrations below the MTCA Method A Cleanup Guidelines (200 ppm for diesel TPHs). • Based on .these results, further soil excavation was not required nor recommended. Based on the TPH concentrations detected in the soil stockpile (490 ppm), the soil stockpile designated as a ' Class 111. non -hazardous MICA waste material. According to Ms. Janice Dimick, the petroleum contaminated soil stockpile was subsequently transported by Rabanco and disposed of at Rabanco's permitted landfill facility. The UST system excavation was bapkfilled with clean fill material to subgrade and finished with asphalt under OPEC supervision.

Simons Site Assessor Nowicki & Associates Inc. 33516 9th Ave 5 Federal Way, WA 98003 Excutive Sumrna One approximately 5000 gallon gasoline storage tank and dispenser were removed on 2/9/93 from the Federal Way Rental Mart Site. Contamination was found on top of the tank and on the west side of the tank. Tank and contamination were removed on the afternoon of 2/9/93, Lab analysis done on samples taken at the end of the day showed soils at the site to be below Model Toxic Control Act (MICA) standards for a clean site. Fifty -,yards of soil was stored next to the excavation site and lab anasis showed showed dlead hislevels it toe e contaminated. Lead analysis on stockpiled soil below MTCA cleanup levels. Site Hist � and Uses Light commercial uses are prevelont along Pacifice Highway. A junior high school is located directly behind the property. A warehouse shop is found to the south of Rental Mart. Accross fhe street to the east and up an embankment are apartments which were built within the last five years. Across Dash Point Road to the north is an abandonded service station(now a used car lot) which had its tanks and contamination removed within the last two years. Prior to the site's current use a tire shop was located on the property facing Pacific Highway. Enclosed is a site sketch showing a foundation and sewers from the former buildings. The gasoline tank removed was installed next to the septic tank and sewer from this demolished structure. Abandonded piping and a concrete pad were located a few feet west of the pump island. Upon excavation this piping appeared to have served an underground tank which had been removed many years ago. Probably this older tank had been in the same area as the present tank which was removed on 2/9/93. Tank installation was done just prior to 1970 which makes the installation approximately 25 years old. Tank Removal 2/9/9 Cleaning and inerting of the tank was complete just after 10:00 AM. Representatives from the City of Federal Way Building Department and the local Fire District were onsite at this time to witness the inerting process. Asphalt was cut around the outline of the proposed excavation, but upon actual excavation it was found that the dispenser was over the middle of the tank and the excavation was expanded to compensate. This top to the tank was exposed by about 11:00 AM. Contamination was evident around the plumbing and the top of the tank. Tank removal was accomplished just before 12:00. Tank condition was good with minimal corrosion and no visible holes. Contamination showed on the west side of the tank and flowed down the tank spreading to the west along the entire length of the tank. Dark grey soil with gasoline odor was excavated west about eight feet. A 4- inch sewer pipe connected to an approximately 104❑ gallon septic tank was discovered during the excavation of contaminated soil. The sewer tank was located just to the northwest of the tank. North, south, and east sidewalls along with the bottom appeared to be clean. Excavation progressed west past the sewer pipe approximately eight feet along the entire length of the tank, A strong odor of organics or waste petroleum and solid grey soil was still noticeable on the west side of the excavation. Field screening with the Tank Techtor was done with negative results. Sewer often .introduces, on_ odor :like waste_ _ - : 1petroleum-:and: this .was_later. foundao be thO cash.` = At approximately 3:30PM samples were taken and sent to Spectra Labs of Tacoma. WA for lab analysis. WTPH-G and BTEX were run on the five excavation samples following DOE Sampling guidelines. Sample results showed the excavation to be below Model Toxic Control Act (MICA) regulations for a clean site. Sample analysis done on the stockpile confirmed contamination by gasoline. Lead sample analysis was 74 PPM which is below r b I the MTCA cleanup level of 250 PPM. No groundwater was encountered during excavation. Approximately. 50 yards of stockpiled soil was placed on 6 mil plastic and the pile. covered with 6 mil plastic at the end of the work day. Closure of this site is recommended.

The site consists of a 1.75-acre land Parcel occupied at the time of this investigation by a vacant 6,350 square foot one-story commercial building located in the southern portion of the site. The building was reported to have been constructed nt in 1970 and has been utilized as an equipment rental facility since that time. Land use in the site viciy consists of both commercial and residential interests. Figure I depicts the location of the project area on a topographic map (Poverty Bay, W,4), United States Geological Survey topographic map, 7.5-minute series, 1:24,000 scale, 1961, Photorevised 1994). The work was conducted by ATC Associates Inc. during the period of September 17, 2000 to January i2, 2001 in general accordance with Union BaWs Letter of Authorization for Union Bank of California File Lag I.D. No. E00-I339-T dated September 11, 2000 pursuant to the Professional Environmental Services Agreement between Union Bank of California and ATC Associates Inc. dated 1 I February 2000. The work was conducted at the request of and by the authorization California. ❑f Ms. Cynthia Wagner of Union Hank of 1.2 Objectives The objective of the subsurface investigation was to evaluate the likelihood that elevated concentrati of petroleum ,hydrocarbons, volatile organic compounds (VOCs) and heavy metals are present ions vicinity of UBOC-specified site features, n the In addition, a supplemental objective was to evaluate whether a reported septic tank was present in an area where a geophysical anomaly was found during the initial stage of the subsurface investigation. 1.3 Scope The scope of work that was developed initially to meet the scope of work was consistent with that requested by UBOC in its request for proposal dated August 31, 2000. Following the completion of the geophysical survey and the utility scan on September 29, 2000 and October 2, 2000, the scope of work was modified to that described below. Health & Safety Plan Geophysical Survey Sump Outlet (Utility Scan) Soil Sample Collection via Geoprobe Drilling Equipment Laboratory Analyses of Selected Soil Samples UST Exposure Based on the Results of the Geophysical Survey Report and Management The number of borings, their respective depths, and the analyses that were conducted are summarized in Section 5. ATC Associates Inc.���— � � — — i � ��— - Project No. 76.17883.0901 PHASE H SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington 2.0 BACKGROUND According to a Phase I Environmental Site Assessment (ESA) of the site performed by Kleinfelder, Inc. in June 2000, the following environmental concerns were reported to be present at the site: ■ Historical review indicated that a combination restaurant and gasoline service station occupied the eastern portion of the site from approximately 1920 to the late 1960s. The number and location of the USTs associated with the gasoline station was not disclosed. The approximate location of the former gasoline station building is shown on Figure 2. In 1993, a 500-gallon diesel UST located in the southwest portion of the site was removed. According to Mr. Lee Forte, manager of United Rentals (previous tenant of the site), this UST was used by the equipment rental business. At the time of removal, all petroleum hydrocarbon -impacted soils were reported to have been removed..- A 5,000-gallon gasoline UST (presumably from the former gasoline service station) located in the northeastern portion of the site was also removed in 1993. At the time of the UST removal, all impacted/contaminated soil was reported to have been removed. The approximate locations of these former USTs are shown on Figure 2. ■ A 1,000-g4llon septic tank was reported to have been left at the site. It was reported by Kleinfelder, Inc. (2000) to be north of the former 5,000-gallon UST that was removed in 1993. + Following demolition of the gasoline service station, the existing site building was built on the southern part of the site in 1970. ■ The site has been occupied by an equipment rental business since 1970, however the site is currently vacant. + Several sumps were located both on the outside and inside of the building at the site. Water was present within the sumps and evidence of petroleum staining around the sumps was observed. Based on the results of a Phase I Environmental Site Assessment (ESA) which included a number of the above observations, Kleinfelder, Inc. (2000) recommended the following: • The performance of a geophysical survey of the site in order to further assess the presence of USTs or septic tanks that may be present from the former gasoline station. ■ The completion of a subsurface soil sampling program in the areas adjacent to the two collection sumps located within the on -site structure, in the location of the former gasoline and diesel USTs removed in 1993, and in the location of the pump dispensers located at the former gasoline service station. These and other concerns cited in UBOC's RFP were addressed in the scope of work described above for this subsurface investigation. According to Kleinfelder, Inc. (2000) the site would be expected to be underlain by glacial deposits of the Vashon Drift which include dense, compact till and various types of glacial outwash. In ATC Associates Inc. J 2 Project No. 76.17883.0901 PHASE II SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington conversations with representatives of UBOC who are familiar with the area, it is ATC's understanding that the site is located in a former stream valley which lay approximately 30 feet below M present ground surface (bgs). The former stream/creek is reported to have been diverted to a drain that lies at a depth of approximately 30 feet bgs and trends approximately north -south across the eastern part of the site. No information on the depth to groundwater was reported in the immediate site vicinity by Kleinfelder (2000). The report stated that a water well located approximately 1.2 miles south of the site had a static water depth of approximately 45 feet bgs. The reported groundwater gradient was to the west-northwest (toward Puget Sound). ATC's experience with other sites in the general area of site is consistent with this reported depth to groundwater and gradient. 3.0 GEOPHYSICAL SURVEY On September 19, 2000, a geophysical survey was performed across the site by Apollo Geophysics Corporation (AGC) under subcontract to ATC. AGC elected to use electromagnetics (EM) and ground penetrating radar (GPR) for the geophysical survey. The purpose of the. survey was to evaluate the presence of buried ferrous objects throughout the site. AGC condudted its survey by initially traversing the entire site on 5-foot line spacings with the EM equipment. The GPR was then used to evaluate anomalies found by the EM equipment. AGC's report, including the equipment used, is included in Appendix A. AGC reported three anomalies which they interpreted to be indicative of subsurface features during their geophysical exploration. The location of each of these anomalies is shown on Figure 1 in the Geophysical Survey Report in Appendix A and summarized as follows: AGC anomaly #1, located approximately 50 feet north of the northeast comer of the building at the site, indicated the presence of a potentially "crushed" UST. AGC anomaly #2, located in the vicinity of the reported septic tank on the eastern portion of the site, indicated the potential for several pipes entering the septic tank area. AGC anomaly #3, located in the northwestern portion of the site, indicated the presence of a potential UST. In addition, AGC located and marked the outfall from the on -site sumps. According to AGC, the outfall was located approximately 50 feet north of the existing building at the site. This corresponded with a surface drain to the storm water sewer system. The surface drain is approximately three feet in diameter. This outfall is the subsurface discharge point where the drain from the sumps discharges into the storm water sewer. AGC marked the locations of these subsurface features on the asphalt pavement using white marking paint On September 29, 2000, Emerald (under subcontract to ATC) used a backhoe to excavate the areas of the three anomalies. AGC_ anomalies # 1-and #3 were found to have metal auto parts' debris at the depth interval of 5 to 8 feet bgs. No evidence of petroleum impacts (such as staining associated with petroleum hydrocarbons) to the soil was noted in these areas. The excavations were filled with the same soil that was excavated from these areas. However, one UST was found at approximately eight feet bgs in the area of AGC anomaly #2. This UST was investigated further as discussed below. ATC Associates Inc. 3 Project No. 76.17883.0901 PHASE II SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington 4.0 UTILITY SCAN Utility Detection Services (UDS) utilized a 60-cycle Metrotech 6890 (line locator) to detect energized electrical lines and an A-10 Metrotech Line Locator to detect metallic objects (i.e., water lines, telephone cables, corrugated pipes) in the proposed boring locations. No utilities were identified by UDS in any in the vicinity of any of the proposed boring locations. 5.0 SUBSURFACE INVESTIGATION 5.1 Health and Safety Plan The Health and Safety Plan was prepared by ATC prior to commencement of the fieldwork. It is the policy of ATC to provide a health and safety plan for all projects where hazardous wastes potentially may be found. The Health and Safety Plan is designed to minim _ e exposure of personnel of ATC and its subcontractors to potentially hazardous waste. 5.2 Soil Investigation Following the completion of the geophysical survey and the exposure of the UST in the eastern portion of the site, ATC and UBOC discussed the number, location, and depth of borings to be drilled. Based on those discussions, on October 2, 2000, a total of ten (10) direct -push sampling probe borings (B-1 through B-10) were advanced at the locations shown on Figure 2. The following table indicates the boring location, boring depth and the type of laboratory analysis that were performed for each analyzed soil sample. The depth of some borings was less than planned due to difficulty in advancing the drilling equipment to the desired depth (e.g., refusal). The planned depth is shown parenthetically in the following table.

ATC Associates Inc. 5 Project No. 76.17883.0901 PHASE II SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington Differences in the actual boring depths versus the proposed boring depths were due primarily to boring refusal (typically caused by large cobbles). Boring B-3 was advanced to 16 feet bgs to evaluate conditions of the nearby UST discovered on September 29, 2000. TEG Northwest, Inc., under subcontract to ATC, used a truck -mounted StrataprobeTM direct -push probe ,apparatus to advanced the soil probe borings. All of the probes were advanced to approximately 4 to 16 feet bgs. The borings were logged by an ATC Project Manager and reviewed by a Certified Professional Geological Scientist. Soil samples were examined for evidence of impacted soil (such as staining or odors) and scanned using a photoionization detector (PID). The soil samples were placed into laboratory -provided glass containers. The collected soil samples were placed into a cooler chilled with "blue" ice and transported to the laboratory following chain -of -custody protocols. The soil samples were sent to TEG Northwest Inc. in Lacey, Washington for analysis. Soil samples with obvious indications of impact by petroleum hydrocarbons were analyzed for the presence of gasoline - range organics (GRO) total petroleum hydrocarbons (TPH) using Method NWTPH-G, diesel- and oil - range organics (DRO) TPH using Method NWTPH-Dx and for BTEX using EPA Method 8021B. 5.3 Subsurface Conditions The soil conditions encountered consisted of brown, dry to moist silty sand with gravel and cobbles in the upper 13 feet. Below 13 feet to the bottom of the borings at approximately 16 feet bgs were gray, silty, gravelly, medium to fine sands. In ATC's judgment, all of the soils encountered were non-native fill material. This judgment is based on the presence of the amount of demolition debris (i.e., concrete, car parts, tires and wood) found while excavating to the top of the UST. Groundwater was not encountered in any of the borings. However, the two borings drilled to a depth of 15 to 16 feet bgs encountered wet -soil conditions indicative of possible seasonal perched water. Boring logs are included in Appendix C. Petroleum -impacted soil was encountered in boring B-3 at a depth of approximately 11.5 feet bgs. This soil was observed to be visually stained, had a petroleum odor and had a low PID reading of 2.0. No other borings had observed field indicators of petroleum hydrocarbons or VOCs. 5.4 Soil Sample Observations and Laboratory Analyses One to two soil samples were collected from each boring (B-1 through B-10) and submitted for analysis. Field screening of soil samples using a PID revealed no detectable organic vapors in the soil samples except for one soil sample in boring B-3 at a depth of approximately 11.5 feet bgs. Sample B-3 (11.5 — 12.0) was analyzed for the presence of GRO TPH and BTEX. Laboratory analysis revealed that sample B-3 (11.5 - 12.0') did not contain detectable concentrations of either GRO TPH or BTEX. As discussed above, the remaining soil samples collected from borings B-1 through B-10 slowed no visual indications that soil was impacted by petroleum hydrocarbons or VOCs. The soil sample analytical results and chain -of -custody documentation are included in Appendix B. Soil sample B-5 (10-10.5) contained 140 milligrams per kilogram (mg/kg) lead. Soil samples B-4 (7.5 — 8.0) and B-10 (3.5 — 4.0) both contained 21 mg/kg chromium. These concentrations are not considered significant as discussed below in Section 7. ATC Associates Inc. 6� �� Project No. 76.17883.0901 PHASE II SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington No VOCs were detected in any of the analyzed soil samples. 6.0 UST EXCAVATION Based on the results of the geophysical survey, feature #2 was interpreted to be a possible UST along the eastern portion of the site. On September 29, 2000 the area in this anomaly was excavated and the top of a UST was exposed. The interior of the UST was observed to have a minimal amount of liquid in the bottom of the UST. The UST was observed to be oriented in an east - west direction. It was estimated to be approximately seven feet long and three feet wide with an estimated capacity of 750 gallons. The top of the UST was encountered at a depth of approximately eight feet bgs. Soil was excavated to a depth of approximately nine feet, around the UST. No evidence of petroleum -impacted soil was observed during the exposure of the top of the UST. Following the confirmation of its presence, the UST was covered with the excavated soil pendiug finalization of the scheduling to remove the UST. 7.0 DISCUSSION The results of the geophysical survey were used to locate where the outfall (subsurface discharge point) from the on -site sumps discharged into the sewer. According to AGC, the outfall was located approximately 50 feet north of the existing building at the site at the location shown on Figure 2. Boring B-5 was drilled in the vicinity of this sump discharge location. No evidence of impacted soil was observed in the collected soil samples and no DRO or GRO TPH or VOCs were detected in the analyzed soil sample collected at a depth of approximately 10 feet bgs. No metals were detected except'for lead, which was detected in the analyzed soil sample at a concentration of 140 mg/kg. The State of Washington Model Toxics Control Act (MICA) Cleanup Level for unrestricted land use for lead in soil is 250 mg/kg. Based on these results, there is a very low likelihood that the soils in the vicinity of this discharge location have elevated concentrations of petroleum hydrocarbons, VOCs or heavy metals. Likelihood statements are discussed in Appendix D. The results of the geophysical survey also were interpreted by AGC to show that there were three features indicative of a possible septic tank and two possible USTs at the locations shown on Figure 2. Subsequent excavation in the area of each of these anomalies found metal debris in the area -of two of the anomalies (AGC anomalies #1 and #3). No evidence of impacted soil was observed in the - soils excavated in these areas. An approximately 750-gallon UST was found in the area of AGC anomaly #2. No evidence of impacted soil was observed in the soils excavated from above the top of this UST. Following its observation, the UST was recovered with excavated soil until such time as it could be decommissioned by removal under an agency permit. Boring B-2 was advanced near the east side of this 750-gallon UST. No evidence of impacted soil was observed in the collected soil samples and no DRO or GRO TPH, VOCs, or metals were detected in the analyzed soil sample collected at a depth of approximately 15.5 feet bgs. Based on these results, there is a low likelihood that the soils in the vicinity of this UST have elevated concentrations DRO or GRO TPH, VOCs, or metals. The results of the drilling, soil sampling, and laboratory analysis of soil samples collected in the vicinity of the four sumps included no observed field evidence of impacted soil or detectable concentrations of DRO or GRO TPH, or VOCs (including BTEX). No heavy metals were detected in any of the analyzed soil samples except for chromium which was detected in borings B-4 (7.5 — 8.0) and B-10 (3.5 — 4.0). ATC Associates Inc. 7 Project No. 76.17883.0901 PHASE H SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington Both samples contained 21 mg/kg chromium. This concentration is below those reported to be "normal' in soils in general and soils in the western United States (Fink, 1996; Shacklette and Boerngen, 1984). The Model Toxics Control Act Method A Cleanup Level for chromium in soil is 100 mg/kg. Based on these results, there is a low likelihood that the soils in the vicinity of this UST have elevated concentrations of DRO or GRO TPH, VOCs, or metals. The results of the soil sampling in boring B-2 near the former 5,000-gallon gasoline UST decommissioned in 1993, the 750-gallon UST and the formerly reported septic tank showed no field evidence of petroleum hydrocarbon impacted soil. No DRO or GRO TPH, VOCs, or metals were detected in the analyzed soil sample collected at a depth of approximately 15.5 feet bgs. Based on these results, there is a low likelihood that the soils in the vicinity of this UST have been impacted by DRO or GRO TPH, VOCs, or metals. No evidence of impacted soil was observed in sampled soil in boring B-3 (in the area with of an asphalt -patch indicative of a possible UST) except for a thin zone (approximately one -inch thick) of stained soil that was observed in soil collected from a depth of approximately 11.5 feet bgs. This thin zone of stained soil had a petroleum odor and a low PID reading of 2.0. The soil sample collected in this depth interval was analyzed was for GRO TPH and BTEX. Analytical results of this soil sample revealed no detectable concentrations of GRO or BTEX: Based on these results, there is a low likelihood that the soils in the vicinity of this UST have been impacted by GRO TPH and BTEX. 8.0 CONCLUSIONS Based on the results of this investigation, current regulatory guidelines, and the judgment of ATC, the following conclusions have been drawn: ❑ A geophysical anomaly in the eastern portion of the site was found to have one UST of approximately 750-gallon capacity. ❑ During excavation of geophysical anomaly #2, no evidence of the reported septic tank was found. ❑ None of the analyzed soil samples had concentrations of GRO or DRO TPH, VOCs (including BTEX), or metals that exceeded MT CA Method A Cleanup Levels. ❑ There is a low likelihood that elevated concentrations of petroleum hydrocarbons (DRO or GRO TPH); VOCs, or metals are present in soils in the vicinity of the sumps, sump outfall area, drum storage area, and the former 500- and 5000-gallon USTs. 9.0 RECOMMENDATION Based on the results of this investigation, current regulatory guidelines, and the judgment of ATC, the following recommendation is presented for your consideration: ❑ The approximately 750-gallon UST discovered on September 29, 2000 should be decommissioned according to Washington Department of Ecology guidelines. ,ATC Associates Inc. 8 r Project No. 76.17883.0901 PHASE 11 SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington 10.0 REFERENCES Fink, C.R., 1996, A perspective on metals in soils: Journal of Soil Contamination, v. 5, no. 4, pp 329- 359.

The site is located at 29805 Pacific Highway South in Federal Way, Washington. A two -person field crew from APOLLO GEOPHYSICS' completed the geophysical field program on Tuesday, September.19, 2000. We investigated the site with an Electromagnetic (EM) instrument, which locates buried metal objects. We traversed 'the site with the EM instrument on approximate 5-foot line spacings, which produced target areas for. the Ground Penetrating Radar (GPR). We further investigated the target areas using GPR, which enabled us to identify the targets, as potential USTs, underground utilities, or demolition debris. Ground Penetrating Radar established a relative depth, size and ground projection of the object (i.e. to determine if the object was indicative or was not indicative of a UST or utility). Small objects in the near surface, 1 to 2 feet, will respond the same as a larger object (UST) at depth. RESULTS OF THE GEOPHYSICAL SURVEY We investigated the inside the existing building with the GPR instrument for the piping, which connects the sumps together. We traversed the parking lot area with an EM instrument, which • A COST-EFFECTIVE WOMAN OWNED BUSINESS with PROFESSIONAL ASSURANCE • PO BOX 65169 • Seattle, Washington USA 98155-9169 • FAX (206) 365-3058 • Web Site www.apollogeophysics.com Seattle (206) 365-3063 • Spokane (509) 326-2010 • Portland (503) 234-4001 • Toll Free (888) 484-5400 Federal Way, Washington October 4, 2000 Federal Way Site AGC's File No.: 00.347 UST Locate Page 2 found several target areas for further investigation with the GPR instrument, to evaluate their potential as USTs. One of the EM target areas, Target #3, showed potential as a UST after being traversed with the GPR Instrument. We recommend this area to be further evaluated with direct exploration. Target area #2 showed potential as a buried septic tank after being traversed with the GPR instrument. We recommend this area to be further evaluated with direct exploration. The GPR Imagery indicated the potential for several pipes entering the septic tank. The GPR Imagery for Target #1 was not indicative of a UST however; the Imagery may indicate the potential for a crushed UST. We recommend this area to be further evaluated with direct exploration. The approximate locations of the pipes connecting the sumps inside the building and the approximate locations of target areas #1 through #3 are shown on the Site Plan in Figure 1. The GPR images for target areas #1 through #3 are presented in Figures 2 through 6. All EM target areas and recommended direct exploration locations were marked in the field with environmentally degradable paint. Suspected pipes, demolition debris, etc., were not marked in the field. The `GPR Imagery' presented in Figures 2 through 6 have a horizontal and vertical scale of approximately 1 inch equals 4 feet. With regard to the estimated vertical scale, the normal relationship between radar time and actual depth for the Northwest Region is approximately 4 to 4.5 nanoseconds per foot. It should be noted that this relationship holds true in a general sense. Variations of water content, silt content and other factors, such as the presence of concrete flooring, may also change this relationship. Therefore it should be expected that the vertical scale is an estimate only and may vary from the shown scale. ELECTROMAGNETIC The electromagnetic, or EM device, transmits and receives an electromagnetic signal. The EM signal is transmitted through the ground, which in turn radiates a signal that is dependent on the ground conductivity and which is also received at the receiver. The two signals, the transmitted Apollo Geophysics Corporation www.apollogeophysics.com 0 This Document is Printed on Recycled Paper Federal Way, Washington Federal Way Site UST Locate October 4, 2000 AGC's File No.: 00.347 Page 3 and ground response EM waves, are balanced for a zero response in the instrument. When the ground conditions change, for example, when the transmitted signal encounters buried metal, the balance or null point changes, andthe instrument responds with an audible signal. Depending on the size of the metal object, the penetration is up to 10 feet in depth. The EM survey was limited in areas, where reinforcing steel was present in the concrete or immediately adjacent to any above ground metal objects on the site. GROUND PENETRATING RADAR APOLLO GEOPHYSICS uses a PE1000 with. either a 450 or 110 MHz antenna for shallow UST Locates. The radar antenna transmits an electromagnetic step -pulse at a frequency of 450/110 MHz at a selected stack rate of 32/64. When the signal encounters a change in electrical properties/permittivity, a portion of the signal energy is reflected back to the surface. The character of the reflection is used to define the source of the reflection. The reflected signal is received by the antenna, processed by a DSP radar processor with signal gain control and the raw data is recorded by the outboard 80486 computer with 16 MB RAM & 300 MB Hard Drive. The radar data is displayed by the computer on a 16.5 cm Color Active Matrix LCD VGA screen in real-time. The radar displays the data in real-time, which enables us to review the data in the field for on the spot evaluation. The recorded raw data, as recorded by the computer, is then later processed to remove unwanted peripheral effects by proprietary GPR software. A typical circular UST will produce, in cross-section, a hyperbolic reflection. A traverse parallel to the centerline of the UST will show a horizontal -(if there is no velocity or elevation change along the traverse) reflection, with a partial hyperbolic signature at both ends of the UST. The hyperbolic signature is the result of "seeing" the tank before the center of the antenna is over the tank. WARRANTY OF SERVICES Electromagnetic methods may'define UST's constructed of non-ferrous metals, but not fiberglass or plastic materials. Ground Penetrating Radar may define fiberglass or plastic UST's or drums provided they fall within the exploration grid of the GPR.

Soil samples were collected using a direct -push Strataprobe rig equipped with a split -spoon sampler and acetate sample tubes. 2. Soil samples were collected on a generally continuous basis, although in selected locations the retrieved sample was less than 100%. 3. Each sampled interval was approximately 4-feet long (e.g., from 0 to 4 feet bgs for the "4-foot depth interval." 4. Soil from each sampled interval was removed from the sampler by nitrile-glove hand and placed in a 4-ounce soil sample jar. A new glove was used for each sample interval. The jar was overfilled to minimize the likelihood of loss of volatile compounds. The jar was then capped with a screw -type lid. The sample jars were supplied by the laboratory. The remainder of the soil was placed in a ziploc-type bag that was then "sealed", the sample disagreggated, and then set aside for approximately 15 minutes. A 5. PID was calibrated to 100 ppm isobutane was then used to "sniff' the bagged sample. 6. Lithologic descriptions were recorded on boring logs along with observations regarding staining or odors and the PID readings. 7. The sampler was washed between sampling locations, using a bristle brush, with a detergent solution; this was followed by two tapwater rinses and a deionized-water rinse. The sampler was dried by air or with a paper towel prior to being used for sampling. S. The sample jars were placed in an ice chest cooled using ice and/or blue ice to a temperature of approximately 40 degrees Fahrenheit. 9. The samples collected for chemical analyses were delivered to the laboratory within 24 hours of collection. Sample handling, transport, and delivery to the laboratory were documented using chain -of -custody procedures, including the use of chain -of -custody. 10. Following completion of the borings, they were backfilled with hydrated bentonite.

Project No. 76.17883.0901 PHASE 11 SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington APPENDIX D LIKELIHOOD STATEMENTS Many statements have been made in this report regarding the likelihood of the occurrence of certain adverse events. The term "likelihood," as used here, pertains to chances -of a match between the prediction for the event and its actual occurrence. Likelihood statements are based on the professional judgments of ATC Associates Inc. A prediction made for the occurrence of an event will either match the actual occurrence or not. Uncertainty about the natural processes, lack of adequate scientific understanding of the physical and chemical interactions at the site, and insufficient data and information about the specific site conditions usually preclude a perfect or 100 percent likelihood of match between predictions and actual occurrences. Therefore, where a perfect match is not possible, the likelihood statement assigns a measure for a "degree of belief' or a "betting score" for the match between the prediction for the event and the actual event outcome. The likelihood statements can be made either qualitatively, expressed verbally, or quantitatively, expressed in percent ranges. The qualitative terms expressed verbally, however, can be approximately related to percent ranges. The following approximate percent ranges have been used by ATC Associates Inc. for the qualitative terms used in likelihood statements. QUALITATIVE TERMS APPROXIMATE PERCENT RANGE Very Low Less than 10% Low 10% to 20% Low to Moderate 20 % to 40 % Moderate 40% to 60% Moderate to High 60% to 80% High 80 % to 90 % Very High More than 90 % ATC Associates Inc. Project No. 76. I7883.0901 PHASE II SUBSURFACE INVESTIGATION Ruth Evans Trust Federal Way, Washington The following is a typical likelihood statement and its interpretation. Statement: Based on site conditions, data collected, and current regulatory guidelines delineating a hazardous waste, it is the judgment of ATC Associates Inc. that there is a low likelihood that hazardous waste from the landfill has migrated to the site. Interpretation of Statement: The statement reflects an extrapolation of a discrete data set to the entire site. This statement is made within the context of regulatory guidelines delineating hazardous wastes in effect at the time the statement is made. It is important to note that these guidelines periodically change; consequently, the judgment made corresponds to the guidelines cited in the report. An extrapolation made from a discrete data set precludes making a statement with certainty that the event has occurred (i.e., one cannot really say with 100 percent certainty that hazardous waste from the landfill has not migrated to the site). Therefore, a professional judgment is made for the event that is expressed in terms of the likelihood (less than 100 percent) that the event either has or has not occurred. The statement given above renders a professional judgment that there is a low likelihood that the event has occurred. The above statement could also have been expressed as "there is a high likelihood that hazardous waste from the landfill has not migrated to the site."

PROJECT NO.76.17883.0902 UNDERGROUND STORAGE TANK SITE ASSESSMENT AT THE RUTH EVANS TRUST SITE 29805 PACIFIC HIGHWAY SOUTH FEDERAL WAY, WASHINGTON 99003 1.0 INTRODUCTION A former gasoline service station and restaurant were present at the site based on the results of a Phase I Environmental Site Assessment (ESA) conducted by Kleinfelder, Inc. (dated June 13, 2000). The former gasoline service station was situated in the northeast portion of the site. Previously, two underground storage tanks (USTs) were removed by others in 1992 and 1993. UST Closure Reports for these USTs were included in the Kleinfelder, Inc. (2000) report. The ESA indicated that other USTs could be present at the site. A geophysical survey was conducted at the site under subcontract to ATC Associates Inc. (ATC) of the site and an anomaly was found in the eastern part of the site in approximately the location shown in Figure 2. The area in the vicinity of this anomaly was excavated and an UST was found. This UST is designated in this report as T1. The results of this geophysical survey and excavation were summarized in a report prepared by ATC (2001). At the request of Union Bank of California (UBOC), ATC has performed an Underground Storage Tank Site Assessment and oversaw the UST decommissioning at the Ruth Evans Trust site located at 29805 Pacific Highway South in Federal Way, Washington. This report summarizes the results of the assessment and decommissioning. State of Washington Department of Ecology (Ecology) and International Fire Code (IFC) registered site assessors and decommissioning supervisors, Ms. Donna Hewitt (IFCI# 1044716-26) and Mark Watts (IFCI# 92954), monitored the UST decommissioning. The contractor performing the UST decomissioning and related excavation activities was Emerald Services (Emerald). Emerald provided these services under subcontract to ATC. 2.0 SITE CONDITIONS 2.1 UST Locations During the subsurface investigation conducted by ATC in October 2000, an UST (T-1) was discovered in the northeastern part of the site. The UST location is shown in Figure 2. As discussed in Section 3.1, during removal of UST T-1, two additional USTs (designated as USTs T2 and T3) were encountered and removed. The capacity of the each UST was estimated to be approximately 750 gallons (the contractor cited different capacities in the disposal paperwork, the capacities cited here are based on measured dimensions. The USTs were located on the northeastern portion of the site approximately 50 feet south of the northern property boundary and 25 feet west of the eastern property boundary (the property line is assumed to be consistent with the fencing around the site perimeter). This location is approximately 150 feet north of the northeast comer of the existing building. During UST removal activites, a concrete foundation including walls and a concrete floor slab was uncovered. The USTs were located in the vicinity of the former gas station. ATC ASSOCIATES INC. 1. PROJECT NO.76.17883.0902 2.2 Buried Building Foundation Walls and Concrete Floor Slab During removal of the three UST's, part of what appeared to be an old building foundation was discovered. It appears that the aboveground portion of the building was demolished and the demolition materials were placed in the basement portion of the building which was then filled in with concrete debris, trash and imported fill. Part of this basement portion was exposed as the concrete walls shown on Figure 3 and. a concrete floor slab. Based on the number of tires and the amount of car parts found during soil removal activites it appears that this building was part of the former gasoline service station and possibly had an automobile repair facility. 2.3 Utilities and Stormwater Conduits Utilities (water, telephone and electrical) are present in the immediate vicinity of the UST's along Pacific Highway South that borders the property and located approximately 25 feet to the east of the UST area. Several buried pipes (metal conduits approximately 2 feet in diameter) were encountered at depths of approximately 14 to 17 feet bgs. These pipes were encountered approximately 60 feet west of the eastern property boundary and appeared to be stormwater conduits. The pipes had a north/south direction orientation where they were encoountered (Figure 3). Their exact configuration or why they were installed is unknown. During site exploration a portion of one of the drainage pipes was uncovered, unfortunately broken, but subsequently replaced by Emerald. 2.4 Geology According to the Geology of the Poverty Bay Quadrangle Washington Map USGS, dated 1961, the soil underlying the site is designated "ground moraine deposits." This soil type consists mainly compacted unoxidized till. Soil conditions encountered during ATC's Phase II Site Investigation (ATC, 2001) consisted of brown, dry to moist silty sand with gravel and cobbles in the upper 13 feet. Below a depth of 13 feet below the ground surface (bgs) to the bottom of the borings at approximately 16 feet bgs was gray, silty, gravelly, medium to fine sands. In one of thr borings (B-3), concrete was encountered at a depth of approximately 13 feet bgs. In ATC's judgment, all of the soil. encountered were non-native fill material to a depth of 16 feet bgs based on the wood debris, concrete, and tires, and other materials that were found during the excavation at the site. Soils surrounding the UST's consisted of a mixture of old fill, and construction debris most likely from the demolition of the former service station. Concrete, brick, tires, automobile trash, metal and an old septic tank and lines were visible and removed. Native soil (consisting of silty, gravelly sands) was encountered at approximately 16 feet bgs during UST and PCS removal activities. According to the Kleinfelder ESA, the shallowest water-producting aquifer in the site vicinity belongs to Vashon recessional outwash unit, which consists of sand and gravel. Groundwater was encountered at approximately 45 feet bgs in a well located approximately 1.2 miles south of the site. -Groundwater was reported to have a gradient (flow direction) toward the northwest. During excavation activities associated with the USTs decommissioning, a seasonal perched water zone was encountered. Depending on where in the excavation it was encountered, the depth appeared to be variable: between 14 and 16 feet bgs. This water zone was considered by ATC to be a seasonal perched water zone as discussed further in Section 3.5. 3.0 UST DECOMMISSIONING 3.1 USTs' Removal On November 3, 2000, UST-T1 and UST-T2 were removed. The tops of USTs T1 and T2 were approximately seven feet below ground surface (bgs). Emerald Services, Inc evacuated residual product and inerted the UST's prior to removal. A representative from the Federal Way Fire Marshal's office issued a permit to removed the USTi The UST's were then removed from the excavation. Upon inspection, several areas of corrosion were noted in UST ATC ASSOCIATES INC. 2 PROJECT NO.76.17883.0902 T2; however, no evidence of holes or leakage was observed. During removal of these USTs, part of a buried concrete wall on top of which was what appeared to be an old building foundation, was encountered north of the USTs. The buried concrete wall was oriented in an east -west direction and it extended to a depth of approximately 13 feet bgs. On November 6, 2000, the third UST T3 was removed from the site. The top of the UST was approximately 10 feet bgs. Upon inspection, several holes and areas of corrosion were noted on T3. During removal operations obvious petroleum hydrocarbon -impacted soil (PCS) was noted under and on the east side of the UST T3. The PCS was excavated, segregated from non-PCS, and stockpiled. In additon, seasonal perched water was encountered at a depth of approximately 14 feet bgs and a concrete floor slab was encountered at the base of the buried concrete wall. The depth of this concrete floor slab, located on the north side of the buried concrete wall, was approximately 14 feet bgs. Trash, including car parts and tires,tire rims, concrete, brick, and burned wood, were also discovered in the excavated soil during this portion of the PCS removal operations. All of the UST's were removed to Emerald Services facility to be cleaned. Upon final cleaning, the UST's were then cut up and recycled at Bloch Steel Industries of Seattle, Washington. The documentation for the_ transport of the USTs to Block Steel Industries is in Appendix A. On December 14, 15, and 20, 2000, excavation of PCS continued and was completed to a depth of between 15 and 16 feet bgs. During these activities the concrete floor slab was found to have an area with a sludgelike material that is referred fo here as DRO-impacted concrete (DRO is defined below in Section 3.2). The limits of the DRO- impacted concrete were evaluated with backhoe pits and the observed DRO-impacted concrete was removed from the excavation. Concrete floor slab without the.DRO sludge was left in place. The DRO sludge was scraped off the concrete floor slab and disposed of with the PCS. The scraped concrete and excavated concrete debris that did not have the DRO sludge was removed from the site and disposed of at Rabanco-Roosevelt, Washington landfill. All PCS was removed from the excavation using a backhoe and stockpiled on -site prior to transport to TPS Technologies in Tacoma, WA under manifest. 3.2 Soil Sample Collection and Analysis 3.2.1 Soil Sample Collection_ Procedures Field sampling was performed in general accordance with the Washington State Department of Ecology (Ecology) protocol as described in "Guidance for Site Checks and Site Assessments for Underground Storage Tanks" (Ecology Guidance Document). Soil samples were collected from the backhoe and placed directly into laboratory provided 4- ounce glass jars. Soil was collected by scooping the soil out of the backhoe with the sample jar. An ample amount of soil was placed in the jar and compacted to the degree that there was no observed headspace. Stockpile samples were collected in the same manner (without assistance of the backhoe). Some of the samples were collected directly from side walls in areas that were sufficiently excavated and considered safe for collection. The sample jar was secured with a screw lid and labeled with the sample ID number, the date, and the project number. Soil samples were placed on ice in a cooler and transported under chain -of -custody to TEG Northwest Laboratories, Inc. in Bellevue, Washington for analysis. Soil samples collected were submitted to TEG. Analysis was conducted in general accordance with the methods described above in Section 3.2. Soil samples were given identification numbers that differed in format depending on where the sample was collected and the date. There are some format inconsistencies in how the sample numbers were recorded between the identifiers that ATC used and those that were reported by the laboratory. For example the sample designated as 110600-S l l also may also be cited as S 11 and S-11. These variations are all the same sample. ATC ASSOCIATES INC. 3 PROJECT NO. 76.17883.0902 3.2.2 Laboratory Analyses The Ecology Guidance Document provides a protocol where soil samples can be analyzed using a "screening" methodology. This screening method utilizes an analysis referred to as the NWTPH-HCID. It is used to assess whether a petroleum compound is present. if it is, then the sample can be analyzed for diesel- and oil -range organics (DRO) petroleum hydrocarbons (including kerosene/jet fuel, diesellfuel oil, and heavy oil) using analytical method NWTPH-Dx, and gasoline -range organics (GRO including benzene, toluene, ethylbenzene, and xylenes (BTEX)) petroleum hydrocarbons (including mineral spiritslstoddard solvent and gasoline) using analytical method NWTPH- Gx. All of these methods are based on U.S. EPA Method No. 8015. In addition to these analyses, the sample with the highest GRO concentration (B12) was analyzed for RCRA metals and PCB's in general accordance with U.S. EPA Method Nos. 7000 series and 8082, respectively. The laboratory analytical results are summarized in Tables 1 through 3 and the laboratory reports are included in Appendix B. 3.2.3 LISTS Tl and T2 During the removal of USTs T1 and T2 no evidence of PCS was observed that was considered related to these USTs. Five confirmation soil samples were collected from the UST Tl and T2 excavation to document the absence of PCS. This included two soil samples collected from the bottom of the excavation (samples BS-1 and BS-2). The analytical results from these five samples are summarized in Table 1. They showed no detectable concentrations of petroleum hydrocarbons. It is the judgment of ATC that there had been no release from these USTs. Although no evidence of PCE was observed that was considered related to USTs Tl and T2, it was visually evident that soil in the western part- of the UST T1 and T2 excavation (at the east side of UST T3) was impacted with petroleum hydrocarbons. The impacted soil was excavated, sampled (sample #Stock-6) and analysed. Based on laboratory data this stockpiled soil was considered to be impacted with DRO. An additional sample (#110600-CS3) of this stockpiled material was collected at a later date (November 6, 2000) and analyzed for diesel fuel. The sample contained DRO in the amount of 240 ppm. The results of these analyses are summarized in Table 2 and the additional removal and excavation of PCS is discussed below in Section 3.2.2. In ATC's judgment, this petroleum hydrocarbon impact is the result of a release from UST T3. TABLE 1. SOIL SAMPLE AND ANALYTICAL DATA FROM UST TI AND UST T2 EXCAVATION Sample ..

Depth is in feet below the ground surface (bgs). 3.2.4 UST T3 Four (4) soil samples were collected during the removal of UST T3 on November 6, 2000'. Holes were noted in the UST and obvious PCS was noted underneath the UST and to the south and west of this UST. After laboratory analysis confirmed the presence of PCS (sample #110600-B12) additional overexcavation was conducted and test pits were excavated to evaluate the extent of the PCS and/or the sludgelike material on the concrete floor slab. This is discussed chronologically below. On November 10, 2000 a sample (N-11) was collected along (what was at the time) the northern portion of the UST T3 excavation at approximately 11 feet bgs in visually stained soil. This sample was subsequently reported to have a heavy oil (DRO) concentration of 3,400 ppm (Table 2). On the same day test pit WTP-14 was excavated to the west of the UST excavation and a soil sample was collected to document the western extent of the PCS. No evidence of an impact by petroleum hydrocarbons was observed in test pit WTP-14 and the soil sample (WTP-14) was collected at 14 feet bgs and bad no detectable petroleum hydrocarbons. This test pit served to document the western extent of the PCS. On November 27, 2000 a sludgelike material was found on top of the concrete floor slab. This material had an observed thickness of up to 4 inches. A sample of the material (#112700-02) was analyzed and found to contain 480 ppm of heavy oil (DRO). Based on this analysis and the results of the analysis of sample N-11 (which was considered to be representative of the sludgelike material) this material is referred to here as DRO sludge. On November 29, 200Q additional test pits and overexcavation were completed to evaluate the extent of the PCS, the sludge -impacted concrete floor slab and the extent of building foundation wall. One sample (#112900-TP1-13), collected at a depth of 13 ft bgs in test pit TP1 was reported to contain 800 ppm heavy oil. This was excavated near the western extent of the concrete floor slab and numerous bricks and trash were unearthed in this area as well as part of a chimney and what appeared to be a bum barrel. Excavation activities continued on December 14 and 15, 2000. Additional soil samples were collected in the vicinity of #112900-TP1-13. Samples #121400-03 (at a depth of 16 feet bgs) and #121500-08 (at a depth of 15 feet bgs) were collected and analyzed using NWTPH-HCID. Sample #121500-08 had no detectable petroleum hydrocarbons. However, sample #121400-03 contained detectable petroleum hydrocarbons. Further analysis using-NWTPH-Dx, showed that sample 121400-03 contained less than the Model Toxics Control Act (MTCA) Cleanup levels of 200 ppm for DRO (Table 3). Additional discussion of confirmation soil sampling and analysis is discussed below in Section 3.3. On December 14 and 15, 2000 part of the the excavated PCS (including the DRO sludge which had been scraped off the concrete) and excavated concrete was stockpiled on site and part of it was transported to either TPS Technologies (DRO sludge and DRO-impacted soil) or to the Rabance landfill (scraped concrete). On December 20`s all remaining impacted stockpiled soil was removed from the site and transported to TPS Technologies. Ail PCS transport to TPS Technologies was conducted under manifest.

ATC ASSOCIATES INC. 7 PROJECT NO.76.17883.0902 3.3 Confirmation Soil Sampling and Analysis During removal of the USTs PCS was observed in the area of former UST T3 and immediately beneath part of the southern part of the concrete floor slab (north of former UST T3). With the exception of two samples, the PCS was found to be heavy oil (DRO) with concentrations (where they were above the WDOE Method A Cleanup Level) ranging from 240 to 3,500 mg/kg. The exceptions (in soil samples #110600-B12 and #110600-Wll) had reported gasoline (GRO) concentrations that were either right at the WDOE Method Cleanup Level of 100 mg/kg or less (8.2 mg/kg), respectively. Based on the absence of GRO in other soil samples and the overexcavation of the soil in the area of the soil samples with detected GRO, it is the judgment of ATC that the PCS was impacted with DRO and the two reported GRO concentrations are not considered to be significant. During or following initial soil overexcavation, there were three areas of soil found to be DRO impacted based on laboratory analyses. These areas were subsequently overexcavated and the confirmation soil samples cited in Table 3 were collected and analyzed. As shown in this table, all confirmation soil samples did not have detectable DRO concentrations (e.g., the analytical results were ND) with the exception of sample 121400-03 which had petroleum hydrocarbon concentrations below the WDOE Method A Cleanup Level for DRO of 200 mg/kg.

The three areas of PCS and the subsequent confirmation soil samples are as follows: o The area around soil samples #110600-B12 and #N-11 which had reported concentrations of 3,000 to 3,400 DRO. These soil samples were collected at a depth of approximately 11 to 12 feet bgs. Following ATC ASSOCIATES INC. 8 PROJECT NO.76.17883.0902 overexcavation in these areas, the following confirmation soil samples were collected- which documented the removal of this impacted soil: #121400-01; #121500-04; #121500-05; and #121500-08. These soil samples were collected at depths of approximately 14 to 16 feet bgs (approximately 3 to 5 feet below the depth of the DRO-impacted soil samples). As summarized in Table 3, none of these conf=" ation soil samples had detectable concentrations of petroleum hydrocarbons. O The area around soil sample #110600-Wl l had a reported DRO concentration of 320 mg/kg at a depth of approximately 11 feet bgs. Following overexcavation of this area the following confirmation soil samples were collected which documented the removal of this impacted soil: #121500-06 and #121500- 07. These soil samples were collected at a depth of approximately 15 feet bgs (approximately 4 feet below the depth of the DRO-impacted soil sample). As summarized in Table 3, neither of these confirmation soil samples had detectable concentrations of petroleum hydrocarbons. O The area beneath part of the concrete floor slab that had the DRO sludge where soil sample 112900- TP1-13 was collected at a detph of approximately 13 feet bgs from the test pit which- had the same designation. Following overexcavation of this area the following confirmation soil samples were collected which documented the removal of this impacted soil: #121500-03 and #121500-05. These soil samples were collected at depths of approximately 15 to 16 feet bgs (approximately 2 to 3 feet below the depth of the DRO-impacted soil sample). As summarized in Table 3, neither of these confirmation soil samples had concentrations of petroleum hydrocarbons above the WDOE Method A Cleanup Level of 200 mg/kg for DRO. Upon receipt of the confirmation soil sample analyses, a total of 259.52 tons of PCS and DRO sludge was removed from the site under current State of Washington Department of Transportation Standards (indluding the use of manifests to track transportation and disposal) and disposed of at TPS Technologies of Tacoma, Washington. - Transportation. Transportation and disposal of the PCS and DRO sludge and disposal were conducted by Emerald under subcontract to ATC. Copies of the manifests are presented in Appendix A. Based on the information obtained during the UST removal activities, it is the judgment of ATC that the PCS was likely was the result of leakage from small holes and corroded areas in former UST T3 as well as possibly poor houskeeping during the life of the former service station. It also is ATC's judgment that the lateral and vertical extent of PCS has been characterized and removed. Based on field observations and the results of the confirmation soil sampling and analysis, it is the judgment of ATC that there is a low likelihood that PCS associated with former UST T3 remains at the site. The Washington Department of Ecology UST Site Assessment Checklist (Checklist) has been completed to document the UST and impacted soil and DRO sludge removal. A copy of the Checklist is presented in Appendix D. 3.4 Excavation Backfilling In December 2000, the lower part of the excavation was backfilled with screened pit run and gravel. Above this fill material, non -impacted soil from the USTs' excavation was placed as fill. It has been Emerald's experience that the screened pit run and gravel can be expected to have an inherent compaction of 801/o to 90%. A hydraulic compactor was used to compact the backfilled soil in one to two -foot thick lifts to approximately 90 percent compaction, according to Emerald. This compaction information is considered approximate and should be verified by a geotechnical engineer if -there are to be any significant engineered loads (such as those for buildings) in this area. ATC ASSOCIATES INC. 9 PROJECT NO.76.17883.0902 3.5 Groundwater According to Kleinfelder (in its report dated June 2000), regional groundwater was reported to be approximately 45 feet bgs with a flow direction to the west-northwest. As discussed above and in ATC's report (dated February 2, 2001), this depth and flow direction is based on information approximately 1.2 miles from the site. This depth to groundwater and flow direction is consistent with ATC's experience. Water was encountered intermittently in the site excavation. This water was encountered at a depth of approximately 14 feet bgs in some of the excavations and test pits that were excavated. In other excavated areas and test pits the water was encountered at depths below 14 feet bgs (to 16 feet bgs which was the deepest depth excavated). Based on the depth of this water above the reported regional groundwater table, the heterogeneous nature of the fill at the site (which could result in localized "ponding" of precipitation in a manner consistent with the observed conditions), the historical stream valley above which the site is located (and which has since been filled in), and the intermittent occurrence of water in the site excavations, this water is, in the judgment of ATC, seasonal perched water. In ATC's judgment, any potential impacts to the seasonal perched water are not an environmental concern. This judgment is based on the following: the seasonal perched water was only intermittently present, the source of potential impacts (the former USTs and the petroeum hydrocarbon impacted soil) has been removed, the detected petroleum hydrocarbons at this site were heavier end DRO petroleum hydrocarbons which tend to be of limited mobility, volatility, and toxicity, the depth of the water below the ground surface and distance above the reported depth of the regional groundwater, and the "soil" in which the seasonal perched water is located is debris filled fill which would likely result in the water being less than pristine. - It is also ATC's judgment that there is a very low likelihood that regional groundwater has been impacted by the former DRO-impacted soil at the site. This judgment is based on the results of the confirmation soil sampling and analysis (which had did not have detectable DRO concentrations with the exception of one sample which had petroleum hydrocarbon concentrations below the WDOE Method A Cleanup Level for DRO of 200 mglkg) and the distance (more than 25 feet) between the perched seasonal water and the reported depth to regional groundwater. With the removal of the USTs and DRO-impacted soil the source for any future impacts has been removed. 4.0 DISCUSSION Historically the site had 'a former gasoline service station. In the area of this former gasoline service station, a total of three USTs ultimately were encountered. These three USTs (designated UST T1 through T3) were removed, cleaned and recycled offsite 'at Bloch Steel Industries. Petroleum -impacted soil (PCS) was encountered during UST decommissioning and was disposed of at the TPS Technologies Facility in Tacoma, Washington under manifest. Part of a buried foundation wall and concrete floor slab (indicative of a possible basement floor slab) were encountered in the UST excavation north of where the USTs were located. Some of the concrete floor slab was covered with a sludge -like material (DRO sludge). Where observed, the DRO sludge was scraped off the concrete and disposed of with the PCS. The scraped concrete was disposed of at the Rabanco disposal facility in Roosevelt, Washington. Confirmation soil samples were collected and analyzed following excavation and removal of the PCS, DRO sludge, and the concrete floor slab from which the DRO sludge had been removed. ATC ASSOCIATES INC. 10 PROJECT NO.76.17883.0902 Based on field observations it is the judgment of ATC that petroleum hydrocarbon- (DRO-) impacted soil (PCS) encountered at the site likely was the result of leakage from small holes and corroded areas in former UST T3 as well as possibly poor houskeeping during the life of the former gasoline service station. It is also the judgment of ATC that the vertical and lateral extent of the former PCS-impacted soil has been characterized and that the PCS- impacted soil has been removed from the area of former UST T3. It is ATC's judgment that there is a low likelihood that PCS associated with former UST T3 remains at the site. The age of the UST's is unknown but most likely associated with a service station previously located at the site. No other USTs are known to be present at the site. In ATC's judgment, there is a very low likelihood that regional groundwater has been impacted by the former DRO. impacted soil at the site. This judgment is based on the results of the confirmation soil sampling and analysis and the distance (more than 25 feet) between the perched seasonal water and the reported depth to regional groundwater. 5.0 CONCLUSIONS Based on the results of this investigation, current regulatory guidelines, and the judgment of ATC, the following conclusions have been drawn: • Petroleum hydrocarbon- (DRO-) impacted soil (PCS) encountered at the site likely was the result of leakage. from small holes and corroded areas in former UST T3 as well as possibly poor houskeeping during the life of -the former service station. • The vertical and lateral extent of former PCS-impacted soil has been characterized and the PCS-impacted soil has been removed from the area of former UST T3. ■ There is a low likelihood that PCS associated with former UST T3 remains at the site. • All of the DRO sludge (4.63 tons) observed on the subsurface concrete floor slab has been scraped off the concrete and transported to the Rabanco facility in Roosevelt, WA for -disposal. • All of the observed PCS-impacted soil and the DRO sludge (259.52 tons) was transported under manifest to TPS Technologies in Tacoma, WA for incineration. • The excavation has been backfilled with "clean" fill from the excavation and imported fill that was compacted to approximately 80 to 90 percent. This compaction is approximate. ■ Significant quantities of trash (that included tires, bricks, concrete, car parts, metal, and wood debris) were encountered in the excavations at the site. It is likely that this type of trash is present elsewhere at the site. ■ Seasonal perched water was encountered intermittently at a depth of approximately 14 feet bgs. • Seasonal perched water is not considered to be an environmental concern. ■ There is a very low likelihood that regional groundwater has been impacted by the former DRO-impacted soil at the site. ATC ASSOCIATES INC. 11 PROJECT NO.76.17883.0902 6.0 RECOMMENDATIONS Based on the results of this investigation, current regulatory guidelines, and the judgment of ATC, the following recommendations are presented for consideration: • No further investigation is recommended. • This report should be transmitted to the State of Washington Department of Ecology with a request for site closure. ■ During any future site development, the characteristics of fill at the site should be considered along with the remaining foundation wall and concrete floor slab as they relate to potential foundation (geotechnical engineering) impacts. ■ Compaction of fill in the UST -related excavations should be verified by a geotechnical engineer if there is to be any significant engineered loads (such as those for buildings) in the area of the USTs' excavations. 7.0 REFERENCES ATC Associates Inc., 2001, Report of subsurface investigation at the Ruth Evans Trust property located at 29805 Pacific Highway South in Federal Way, Washington: Unpublished professional report prepared for the Ruth Evans Trust c/o Union Bank of California, Orange, CA, dated February 2, 2001.

The subject property is currently vacant and occupies approximately 13/ acres. A 6,350 square foot one-story commercial steel building is situated on the southern portion of the subject property (Figure 2). The steel building was previously used as part of an equipment rental facility, with office and maintenance/storage areas located in the eastern and western portions of the building, respectively. Land use in the site vicinity is mixed commercial and residential. Our review of aerial photographs suggests that the general area of the subject property was rural in character until the 1950s. An additional review of historical information revealed that a combination gasoline station and restaurant was constructed on the eastern portion of the subject property in 1920 and was present until the late 1960s (Figure 3). The number and locations of the underground storage tanks (USTs) associated with this former service station were not disclosed in the historical information. In addition, information regarding the closure of these USTs was not included in the Department of Ecology UST files. Thus, it is not known whether these USTs have been properly closed or if the soils and/or groundwater quality has been impacted from the potential release of petroleum hydrocarbons associated with these USTs. The existing steel building was constructed in 1970, and has apparently always been an equipment rental_ business, first as Rental Mart, and later as 40-Rentals beginning in about 1995. A 500-gallon diesel UST and a 5,000-gallon gasoline UST were installed on the subject property as part of the former rental equipment operations. These tanks were removed in 1993. Information presented in the UST closure reports indicated that petroleum -impacted soils were encountered in each UST excavation at concentrations above the Washington State Model Toxics Control (MICA) Method A cleanup levels. These impacted soils were reportedly stockpiled on - site and subsequently disposed offsite at the Roosevelt Regional Landfill. No evidence of the petroleum -impacted soil affecting the regional groundwater quality was reported. . During the removal process of the 5,000-gallon gasoline UST previously discussed, a septic tank was observed in the northwest corner of the gasoline UST excavation. No information was 60-208101/6010R074.doc Pave 1 of 23 Copyright 2000 Kleinfelder, Inc.

During our site visit, a drum storage area was observed within the service bay of the building. A total of six 55-gallon drums containing waste oil were located in this area. Evidence of significant petroleum staining was observed on the concrete floor beneath the drum storage area and other locations throughout the service area. Several concrete sumps were observed within the equipment servicing bays and in the asphalt -covered parking lot immediately outside of the service bay (Figure 2). Due to the presence of water in the sumps, the integrity of these sums are unknown; however, evidence of petroleum staining was observed near the sumps. According to Mr. Forte the sumps connect to the storm drain system. Regarding potential off -site sources of impact, several sites were identified within the specified search distances in our review of regulatory -agency databases. Nearby USTs were also identified. In our opinion none of the identified sites are likely. to have impacted the subject property. Furthermore, contamination from such offsite sources (if present) likely does not present an area -wide cleanup liability to the subject property due to Engrossed Senate Bill (ESB) 7900, which provides that the owner of a site that overlies a plume of contaminated groundwater is not strictly liable for that contamination. To address identified issues we recommend the following: • Require the recent property tenant to remove and dispose of the drums of waste oil and paints remaining on the subject property in accordance with applicable local, state and federal regulations. • Complete a geophysical survey of the site in order to further assess the presence of USTs or septic tanks that may be present from the former gasoline station. . • Complete subsurface soil and possibly groundwater sampling in the areas adjacent to the two collection sumps located within the on -site structure, in the location of the former gasoline and diesel tanks removed in 1993, and in the location of the pump dispensers located at the former gasoline station..

This summary and our report are subject to the limitations presented in Section 8.0 of this report. 2.0 INTRODUCTION This work was authorized on May 30, 2000 (Lou #E00-1148-T) and conducted in accordance I with Kleinfelder's Master Service Agreement with Union Bank of California, dated February 22, 2000. The following report is a summary of work performed using the guidelines set forth in American Society for Testing and Materials (ASTM) Standard E-1527-97, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process and Union Bank of California Trust or Corporate Real Estate Phase I Environmental Site Assessment. This report also follows the ASTM Standard's suggested table of contents. KIeinfelder has made minor format modifications- to the suggested table of contents to assist in reading and understanding the report findings. 2.1 Purpose of Assessment KIeinfelder understands that Union Bank of California is interested in identifying site historical practices or activities that may have resulted in soil and/or groundwater contamination at the subject property. The purpose of the Phase I Environmental Site Assessment (ESA) is to evaluate the potential for the presence or likely presence of regulated hazardous or dangerous wastes and/or substances, including petroleum products, under conditions that indicate an existing release, a past release, or a material threat of a release.into the structures of the property or into the ground, groundwater, or surface water of the property. In addition to the Phase I ESA workscope, the potential presence of asbestos and lead -based paint were considered for construction materials that were easily accessible and visible (e.g., assessment of the roof, crawl spaces, under -flooring, or areas requiring demolition' to access was not performed). The site's "Radon Zone Level" was also reviewed, as was the potential presence of on -site wetlands and critical habitats. This report describes Kleinfelder's assessment procedures and the information identified. 1 Opinions and recommendations concerning the potential for soil and/or groundwater I contamination are presented in Sections 6.0 and 7.0 of this report. 60-20810116010R074.doc Page 3 of 23 Copyright 2000 KIeinfelder.

Figure 1 presents a site vicinity map, and Figure 2 presents site plan.. Figure 3 presents areas of environmental concern associated with the previous site activities. Additional site -description information was - " obtained during the site visit and through interviews.. Please refer to the appropriate sections of the report that cover this information. 3.1 Location and Legal Description The subject property is situated at the southwest corner of Pacific Highway South and Dash Point Road at 29805 Pacific Highway South in Federal Way, Washington (Figure 1). The subject property is currently vacant and occupies approximately 13/4 acres. A 6,350 square foot one-story steel building is situated on the southern portion of the subject property (Figure 2). The steel building was previously used as part of an equipment rental facility, with office and maintenance/storage areas located in the eastern and western portions of the building, respectively. The subject property is bounded to the north by Dash Point Road, to the west by 16* Avenue South, to the east by Pacific Highway South, and to the south by a motel. Land use in the site vicinity is mixed commercial and residential. 60-208101/6010R074.doc Page 4 of 23 Copyright 2000 Kleinfelder. Inc. L IF I N F F !A) F h 2401) 14IIIl Awni.w. -NE. Suite'. A101.

Archive information indicates that the address of the former gasoline station/restaurant located on the subject property was 29651 Pacific Highway South. 3.2 Geologic Setting Review of the U.S. Geologic Survey (USGS) topographic map for the Poverty Bay Quadrangle (USGS, 1961) indicates that the property is located at an elevation of approximately 400 feet above mean sea level (MSL). The nearest large surface water body is Puget Sound, located approximately 1-mile northwest of the subject property. The topography in the vicinity of the property slopes to the northwest. 1 The Puget Sound area has been glaciated numerous times over the last several hundred thousand years. The most recent of these events was the Vashon Stade of Fraser Glaciation. The subject site and its vicinity are situated within semi- and unconsolidated materials, deposited during the Vashon Stade of Fraser Glaciation which occurred approximately from 15,000 to 12,000 years ago (Griffin, et al, 1962). The glacial deposits of the'Vashon Drift include dense, compact till and various types of glacial outwash. r The shallowest water -productive aquifer within the subject property belongs to Vashon recessional outwash unit, which consist mostly of sand and gravel. The groundwater was encountered at approximately 45 feet below ground surface (bgs) in the well, located ;1- approximately 1.2 miles south of the subject property. The lower boundary of Vashon recessional outwash is the top surface of Vashon till, very compact and cemented mixture of- fine- and coarse -grained sediments. Ground water in the Vashon recessional outwash, as well as uncontrolled surface water, follow the land -surface gradient; water moves from high -altitude areas towards stream valleys. It can be expected that the water within the site and its vicinity flow toward the Puget Sound, to the northwest. It should be noted that perched groundwater conditions are frequently encountered in shallow soils throughout the Puget Sound area. No I regional groundwater impairments are known to exist in the area. 3.3 Environmental Liens No environmental liens are known to be present against the property. However, Kleinfelder did not have access to a chain -of -title to confirm or dispute our understanding. 60-20810116010R074.doc Page 5 of 23 Copyright 2000 Kleinfelder, Inc.

The following agencies, companies, and individuals were contacted for information regarding the subject property: • Walker and Associates, Aerial Photographs; • VISTA Information Solutions, Inc. (VISTA) Report, May 10, 2000; • Federal Way Fire Department; • King County Library, Seattle Main Branch - Polk Reverse Telephone Directories, Sanborn Fire Insurance Maps, Kroll City Maps, Metsker's Atrases; ' • King County Assessor's Office; • Mr. Lee Forte, proprietor of 40-Rentals; • King County Regional Archives; • Federal Way Building Department; and • Washington Department of Ecology, Northwest Regional Office. 4.1 Federal Environmental Record Sources The following information was obtained from regulatory -agency databases and listings. Search distances were those specified in the ASTM standard. As part of a government database search completed by VISTA Information Solutions (VISTA), the following federal database records were searched as required by ASTM: the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS), Emergency Response Notification System. (ERNS), 'National Priority List (NPL), and the Resource Conservation and Recovery Act (RCRA) Information System (RCRIS) including the Corrective Action Report (CORRACTS), listing of hazardous waste treatment, storage, and disposal facilities (TSDs), and large- (LG GEN) and small -quantity (SM GEN) generators of hazardous waste. Appendix B contains a copy of the complete VISTA report. The dates of the database information are also identified in the VISTA report. Please note that the VISTA report may include search results for several databases not discussed in this report. Kleinfelder's review of the VISTA report focused on the most significant database information, inclusive of the information specified for review in the ASTM standard. The following summaries contain information from the VISTA search. In general, listed sites with known contamination and in close proximity to the subject site are discussed. 60-208101/6010R074.doc Page 6 of 23 Copyright 200010einfelder, Inc. L L El N F E 1.

Also included are sites that -are in the screening and assessment phase for possible inclusion on the NPL. The subject property was not identified on the CERCLIS. However, King County Redondo Oil Pit, located approximately 0.03-mile west of the subject property at } SR 509 and 16`h Avenue South was listed in CERCLIS. A Preliminary Assessment and 8 Screening Site Assessment of the site were completed by EPA, after which no further action is planned. This site also appears on the State SCL with a slightly different address and name (as discussed in Section 4.2, below). This is the current location of Sacajawea Park. This site is not considered a concern for the subject property because it is expected to be hydraulically cross - gradient from the subject property, and is apparently not considered a priority concern. for EPA or the Washington Department of Ecology. 4.1.2 Federal National Priorities List (NPL) The NPL list (i.e. Superfund list) is a compilation of CERCLIS properties with the highest priority for cleanup pursuant to EPA's Hazard Ranking System. Neither the subject property nor any site within a mile of the subject property was identified on the NPL. 4.1.3 Federal Resource Conservation and Recovery Act (RCRA) Information System (RCRIS) and Corrective Action Report (CORRACTS) Database The RCRIS database contains information about facilities registered with EPA as hazardous waste generators, transporters, storage, or disposal facilities. Note, however, that being registered with EPA has a hazardous waste handler does not in itself mean that any hazardous materials have been improperly managed. The CORRACTS Database identifies those sites that are listed by the EPA as hazardous waste handlers with RCRA corrective action activity. Neither the subject property nor any site within a mile of the subject property was identified in RCRIS or CORRACTS. 4.1.4 Generators of Hazardous Waste As previously discussed, the RCRIS database contains information about facilities registered with EPA as hazardous waste generators. Large -quantity generators (LG GEN) are those that 60-208101/6010R074.doc Page 7 of 23 Copyright 2000 Kleinfelder, Inc. KLEIN F ELDER 2405 140111 Avenue, NE. Suite A101.

Small -quantity generators (SM GEN) generate less than the threshold quantities for being classified as Iarge-quantity 'generators. Note, however, that being registered with EPA has a hazardous waste generator does not in itself mean that any hazardous materials have been improperly managed. Neither the subject property nor any site within a mile of the subject property was identified as a hazardous waste generator. I 4.1.5 Federal Emergency Response Notification System (ERNS) ERNS identifies those sites that are listed under the EPA's emergency response notification systems list of reported CERCLA hazardous substance releases or spills in quantities greater than the reportable quantity. This list is maintained by the National Response Center. Notification requirements for such releases or spills are codified in Chapter 40 of the Code of Federal Regulations (CFR) parts 302 and 355. Neither the subject property nor any site within a mile of the subject property was identified in ERNS. 4.2 State Environmental Records Reviews (Washington State Department of Ecology) As part of a government database search completed by VISTA, the following state database records were searched as required by ASTM: the Confirmed & Suspected Contaminated Sites List (CSCSL) List including the Hazardous Sites List (HSL), Leaking Underground Storage Tank (LUST) List, the Underground Storage Tank (UST) Database, and the Solid Waste Facility (SWF) Database. Appendix B contains a copy of the complete VISTA report. The dates of the database information are also identified in the VISTA report. Please note that the VISTA report may include search results for state databases not discussed in this report. Kleinfelder's review, of the VISTA report focused on the most significant database information, inclusive of the information specified for review in the ASTM standard. The following summaries contain information from the VISTA search. 1 4.2.1 Confirmed and Suspected Contaminated Sites List (CSCSL) and Hazardous Sites List (HSL) The Washington Department of Ecology (Ecology) CSCSL is the states' equivalent to CERCLIS. Confirmed contaminated sites are referred to in the VISTA report as State Priorities List (SPL) sites. Suspected contaminated sites as- referred to simply as SCL. Sites being addressed by the Washington State Department of Ecology's Toxics program are listed in the 60-208101/6010R074.doc Page 8 of 23 Copyright 2000 Kleinfelder, Inc. K t.

The HSL is a subset of the CSCSL Report that includes sites that have been assessed and ranked using the Washington Ranking Method (WARM). The subject property was not identified on the SPL, SCL, but was identified in the TOMCS database, and on the LUST and UST lists. Two USTs were removed from the subject property in 1993; a 500-gallon diesel tank and a 5,000-gallon gasoline tank. At the time of removal, soil contamination associated with the gasoline tank was discovered. The contaminated soil was reportedly excavated at the time of tank removal, and the site is reported cleaned up in the LUST database. The UST removal reports for these tanks were obtained from the Washington Department of Ecology and will be discussed later in this report. Redondo Oil Pit King County, located approximately 0.03-miles west of the subject property dt the intersection of 16th Avenue South -and Southwest Dash Point Road is identified in the SCL. This site was discussed in Section 4.1 because it was identified in CERCLIS, but where no further remedial action is planned. As previously discussed, this site is not considered a concern for the subject property because it is expected to be hydraulically cross -gradient from the subject property, and is apparently not considered a priority concern for EPA or the Washington Department of Ecology. Two sites, one within 1/8-mile and another within 1/2-mile of the subject property were also identified in TOMCS. 1. Unocal #6227, located within 100 yards north of the subject property at 29625 Pacific Highway South (the site of the present-day Shell station) is listed in TOMCS, and under the name of 509 Deli Town Pump on the LUST and UST lists. Soil affected by petroleum release from USTs at the site has reportedly'been cleaned up. The UST and LUST files for this site were requested from the Washington Department of Ecology, however Ecology could not locate the files for our review. Nevertheless, this site is not considered a concern for the subject property because it is expected to be hydraulically down - gradient of the property, has reportedly been cleaned up, and only soil was reportedly affected. 2. Texaco #004479, located approximately 0.47-miles north of the subject property at 28806 Pacific Highway South, is listed in TOMCS, and on the LUST and UST lists. Soil contamination at the site has reportedly been cleaned up. The site is not considered a concern for the subject property because it is relatively distance from the subject property, has reportedly been cleaned up, only soil was reportedly affected, and because the site is expected to be hydraulically down - gradient of the subject property. 60-208101/6010R074.doc Page 9 of 23 Copyright 2000 Kleinfelder, Inc.

All three sites are also listed in other databases and were previously discussed. _ Two USTs were removed from the subject property in 1993. Contaminated soil was found to be associated with one of the tanks, which was reportedly excavated at the time of tank removal. The two other sites identified in the LUST database include the 509 Deli Town Pump, now the site of the Shell station located on the north side of Dash Point Road across from the subject site, - and Texaco #004479, located at 28806 Pacific Highway South. As previously discussed, neither of these two sites are considered a concern for the subject property because they are reported cleaned up, only soil was affected, and/or they are expected to be either cross- or down -gradient of the subject property. 4.2.3 Registered Underground Storage Tank (UST) Database The subject property is listed in the UST Database under the name of Rental Mart. The database information lists four tanks; two closed in place, and two removed. However, this information is apparently in error. Each of the two tanks removed in 1993 is likely listed twice in the database, once as closed in place, and once as removed. The size of the tanks and age in each case is repeated among corresponding listings for closed in place and removed. It should be noted, that tanks that were likely associated with the former gasoline station on the property would not be . expected to be listed in the UST database because the; station was demolished prior to 1970, prior to UST notification requirements, and prior to the formation of the Washington Department of Ecology. 509 Deli Town Pump, now the site of the Shell station located on the north side of Dash Point Road across from the subject site, was also identified in the UST Database. In addition to three USTs previously removed from the site, there reportedly four USTs still in service at the Shell station. 4.2.4 State Landfill and/or Solid Waste Disposal Site Database (SWF) VISTA's review of Ecology's SWF Database did not identify that any state landfills and/or solid waste disposal sites were located within 0.5 mule of the subject property. 60-208101/6010R074.doc Page 10 of 23 Copyright 2000 Kleinfelder, Inc.

A Kroll Map dated 1926 depicts the subject' property simply as Lots 33 and 35. The area of the present-day park located several hundred yards west of the subject property is labeled as "King County". This is *the site which shows up in`several agency databases as Redondo Oil Pit King County. 4.3.4 , Federal Way Fire Department We contacted -the Federal Way Fire Department (under the present address and the address of the former service station) regarding any fires, hazardous materials storage incidents, or information concerning USTs associated with the subject property under the current address and the address of the former service station. The Department responded that 40 Rentals had maintained a permit for the storage of flammables and combustibles for several years. The Department also has record of a 5,000 gallon gasoline and 500 gallon diesel tanks present at the property as of 1992. The diesel tank was removed in 1993 according to Department records. No records of any fires or hazardous material incidents were found. 4.3.5 Federal Way Building Department We contacted the Federal Way Building Department concerning any building plans or permits on file for the subject property (under the present address and the address of the former service station) We were provided with a copy of a UST removal permit for the 5,000 gallon gasoline UST, and brief field notes completed by the Fire Marshal upon removal of the 500 gallon diesel UST. No other records concerning the subject property are on file with the Department. According to Tom Noble of the Department, the subject property was likely not incorporated into the City of Federal Way when the Rental Mart was constructed in approximately 1970. 60-208101/601OR074.doc Page 11 of 23 Copyright 2000 Kleinfelder, Inc.

Copies of UST Site Assessment Reports and supporting information for the 500-gallon diesel and 5,000-gallon gasoline USTs removed from the subject property were obtained, and are provided in Appendix C. Ecology indicated that they had log records of having UST and LUST files pertaining to the Shell Station (AKA: Unocal and/or 509 Deli Town Pump); however, the files could not be located for our review. Note that it is not anticipated that Ecology would have any information concerning USTs that were likely associated with the former service station located on the subject property because the station was demolished- prior to UST notification - requirements and before Ecology was formed. Furthermore, as previously discussed in Section 4.2.3, we believe Ecology only has information on the two USTs removed from Rental Mart in 1993, and that the UST Database erroneously lists two other USTs as being closed in place on the subject property. In February 1993, a 5,000-gallon gasoline UST and pump dispenser unit were removed from the eastern portion of the subject property as shown on Figure 3(Nowicki & Associates, 1993). The tank was located on the eastern side of the property, roughly 50 yards north of what was at that time the Rental Mart building. The tank was reportedly installed in 1970 when the Rental Mart 1 was constructed, and had been used for fueling of equipment at the Rental Mart store. At the time of removal, petroleum -impacted soil was found above -the tank (the pump dispenser was situated above the tank) and on the western side of the tank excavation. Approximately 50 cubic yards of petroleum -impacted soil was over -excavated, and confirmatory sampling -indicated the excavation to be clean. The petroleum -impacted soils were removed and disposed of at Roosevelt Regional Landfill. Post -excavation soil samples indicated that the MICA Method A cleanup levels were met. During removal of the gasoline tank, a septic tank and previously abandoned petroleum product piping were encountered. The septic tank was located immediately northwest of the gasoline tank, and the product piping was located west of the gasoline tank (Figure 3). Conjecture in the UST removal report suggests that the septic tank and abandoned product piping was associated with the former gasoline and tire service station that had previously been located on the site (perhaps more accurately, a service station and restaurant based on King County Archive records). The report fails to indicate whether the septic tank and product piping were left in 60-208101/6010R074.doc Page 12 of 23 Copyright 2000 Meinfelder, Inc. K1. F.I N F h L U E k 34+15 14ot11 Avvnui.

The report also mentions a warehouse shop being present south of the subject property, the building that is today a motel. A former service station is described as being 1 present on the north side of Dash Point Road at the location of the present-day Shell Station. This is likely the Unocal/509 Deli Town Pump identified in several agency databases. In May 1993, a 500-gallon diesel UST and an associated pump dispenser situated over the tank were removed from the subject property (Hazcon, 1993). The tank was located approximately 35 feet north of the west end of the Rental Mart building, and was used to store diesel fuel for fueling of equipment. The UST site assessment report indicates that the tank was installed in t 1965, which predates the construction of the Rental Mart facility (constructed in 1970). Analysis of composite samples collected from the limits of the UST excavation found the excavation to be clean (i.e. concentrations below the Method A Cleanup Levels specified in Ecology's Model Toxics Control Act). However, the stockpile of excavated soil was found to contain diesel concentrations above the - Method A Cleanup Levels, and the material was disposed of as petroleum -impacted soil at Roosevelt Regional Landfill. F 4.3.7 King County Assessor's Office and Regional Archives _ A Kleinfelder representative reviewed the tax records and property information for the subject I property at the King County Assessor's Office. Assessor's records indicate that the structure currently present on the subject property was constructed in 1970. The taxpayer is reported as 3 Union Bank of California. Historic tax records were obtained from the King County Regional Archives. The historical records indicate that combination gasoline station and restaurant was formerly present on the eastern side of the subject property, along Pacific Highway South. The facility was constructed in 1920, utilized stove heating, and included several fuel dispensers located immediately east of the southern end of the building. A photograph from 1938 shows a Mobil service station, and a sketch of the layout of the building shows the pump dispensers immediately east of the southern side of the building. The structure was demolished in 1969. As previously mentioned, copies of information obtained from the Assessor's Office and Regional Archives is provided in Appendix A. - 4.3.8 Aerial Photograph Review A review of historical aerial photography may indicate past activities at a property that may not be documented by other means, or observed during a property visit.

The Shell Station has- now been constructed on the north side of Dash Point Road across from the subject property. Note: Aerial photographs only provide information on indications of land use and no conclusions can be drawn from the photographs alone. 5.0 SITE RECONNAISSANCE AND INTERVIEWS Kleinfelder's assessment activities included personal on -site and telephone interviews, and a property visit. This section summarizes.the findings from the site visit, and interviews. On May 16, 2000, an Environmental Scientist (Tim Stott) from Kleinfelder visited the subject property. During the site visit, the Kleinfelder representative was accompanied by Mr. Lee Forte, proprietor of 40-Rentals. The purpose of the visit was to look for visual indications of possible soil and/or groundwater contamination resulting from past or current site use. The site visit included a visual review of the property for indications of activities such as waste storage and disposal, storm drainage, underground and aboveground storage tanks, and hazardous -material storage or use areas. Observed conditions are described below. Photographs taken during the site visit are provided in Appendix D. Mr. Forte indicated that he was aware that a UST had been removed from the site when it was operated by Rental Mart. Concerning hazardous materials used at 40 Rentals, Mr. Forte explained that small quantities of kerosene for retail sale were stored outside of the rental building in the approximate location of the former diesel UST (removed in 1993). Mr. Forte also stated that an above -ground propane. tank had previously been along the eastern side of the property, several .hundred feet north of the rental building. Waste oil was occasionally generated during maintenance of rental equipment, that according to Mr. Forte, was picked up by a waste oil recycling company. The waste oil was stored in :the western site of the service bay in 55- gallon drums. Mr. Forte stated that he was not aware of any environmental liens associated with the subject property, or contamination on the subject property. Two collection sumps were observed in the floor of the service bays in the on -site structures (Figure 2). Two more similar sumps were located on the exterior of the building, one on the north side and one on the west side. One of the collection sumps is located within a few feet of 60-208101/6010R074.doc Page 15 of 23 Copyright 2000 Kleinfelder, Inc. K L E I N F E L U E K 240,5 1 4( 11lt rivcnLit -, !tiE, Suite A 101.

An approximate 50 square -foot area of dark staining was observed on the concrete floor adjacent to the hazardous materials storage area (Drum Storage Area, Figure 2). The concrete of the floor and sump was observed to be cracked in several places. Upon closer inspection, one of the sumps was found to be full of water exhibiting a slight hydrocarbon sheen. According to Mr. Forte, the sumps are connected to the storm water system. Exit piping could be observed in one of the sumps. Several storm drains were observed in the asphalt parking lot. A concrete pad, approximately 50 square feet in size, was observed on the northwest side of the lot. Mr. Forte said the pad dated from when the facility was operated as Rental Mart, and he did not know the purpose of the pad. The construction of the pad is consistent with concrete patching, or for supporting material storage. 5.1 Physical Setting Analysis The subject property consists of a rectangular -shaped pa,cel of land approximately 23,522 square feet in size, which includes a single -story with mezzanine steel structure approximately 6,350 square feet in size (Figure 2). . The subject property is located in a mixed commercial and residential area of Federal Way. The subject property is bound to the north by Dash Point Road, to the west by 16`h Avenue South, to the east by Pacific Highway South, and to the south by a motel. The property is generally flat, with an embankment present along the western boundary below 16th Avenue South. Heating is provided by electric baseboard heating in the office areas of the structure and electricity is provided by Puget Sound Energy. Water and sanitary sewer service is provided by Lakehaven Utility District. Runoff is directed to storm drains located in the asphalt paved parking lot, and within the service bays of the on -site *structure. Utility service was apparently provided when the facility was constructed in approximately 1970. No open ditches or drainage i culverts were observed on the property. The subject property is entirely developed as a commercial business, and no wetlands or critical habitats are present on the property. 5.2 Hazardous Substances in Connection with Identified Uses Several potentially hazardous substances were identified on the subject property during the site visit. Six 55-gallon drums of used oil were observed within a secondary containment pallet in a 60-206101/6010R074.doc Page 16 of 23 Copyright 2000 Kleinfelder, Inc. A L E I N I' E. L U E h 2407) 140th A�.

Approximately six 5-gallon buckets of paint, a 5-gallon bucket of wax stripper, and several gallon cans of paint were also observed in this location. According to Mr. Forte, he plans on having these materials removed. Two collection sumps were observed in the floor of the service bays. One of the collection sumps is located within a few feet of the hazardous materials and area of floor staining. As previously mentioned, the concrete of the floor and sump was observed to be cracked in several places. Upon closer inspecI tion, one of the sumps was found to be full of water exhibiting a slight hydrocarbon sheen. According to Mr. Forte, the sumps are connected to the storm wateF system. Exit piping could be observed in one of the sumps. ; 5.3 Storage Tank Information As previously mentioned, two USTs are known to have previously existed on the subject property associated with the Rental Mart. A septic tank is also known to have existed on the property, and this septic tank may still be present. - Underground storage tank(s) were likely associated with the former service station located on the property, and despite conjecture in one of the reports written when a UST was removed from the Rental Mart, such tanks may still be present on the property. No above -ground storage tanks or evidence of USTs, such as vent or fill lines, were observed during our site visit. 5.4 Indications of Polychlorinated Biphenyls (PCBs) A number of fluorescent light fixtures are present within the on -site structure. The electrical ballasts associated with these fixtures potentially contain PCBs. When these light fixtures are removed, any oil -filled electrical ballasts or other electrical equipment should be segregated, inspected and/or tested for PCBs, and properly disposed of. No transformers were observed on the subject property. 5.5 Indications of Solid Waste Disposal We did not observe any indication of improper disposal of solid waste on the property. 5.6 Other Conditions of Concern Presented below is a listing of other issues reviewed as part of this assessment. 60-20810 l /6010R074.doc Copyright 2000 Kleinfelder, Inc.

Suift' A 101, BUIIiA: ur, WA 98003 1415; 5h2-42010, 14250 562-4 'h I u\ �I 5.6.1 Asbestos and Lead Paint Several suspect asbestos -containing materials were observed in the on -site structure during our site visit, including: "popcorn" textured ceiling, floor tile, and the interior wallboard system. All suspect materials appeared to be in good condition in an intact state, and in our opinion, do not present a health risk in their current condition. However; the Puget Sound Clean Air Agency requires that an asbestos survey be completed by an accredited inspector, and any identified asbestos -containing materials be abated from structures prior to demolition, or re -modeling activity that may disturb the materials. Based on the age of the on -site structure (constructed in 1970), the presence of lead -based paint is suspect. All painted surfaces generally appeared in good condition during our site visit with little pealing or chipping, and in our opinion, the paint does not present a health risk in such non- residential scenarios. Contractors or others who may come in contact with potential lead -based paint should be notified of the potential presence of lead and be advised to follow applicable occupational health and safety regulation. ��. 5.6.2 Radon Information Radon is a naturally occurring gas produced by the radioactive decay of uranium and thorium. Adverse health effects can occur when radon migrates from underlying soils or concrete and accumulates inside structures. The EPA has established a radon concentration of 4.0 pico-Curies per liter (pC/1) of air as an "action level" beyond which abatement measures are recommended. The Puget Sound region of Washington, and the subject site, are underlain by glacially -deposited soils which contain very low concentrations of radon -forming minerals. In 1993, the Washington Department of Health published a listing of radon measurements indicating a- state-wide average of 1.0 pC/l, and a King County average of 0.60 pC/1 (Washington Department of Health, 1993). Furthermore, the United States Environmental Protection Agency (EPA) has identified King County as having a "Average Radon Potential' (<2pC/liter). Based on this information, it is considered unlikely that radon levels on the site exceed the EPA's 4.0 pC/1 action, level especially because there are no basement areas. However, Kleinfelder did not collect samples during this assessment to prove or dispute this expectation. 60-20810116010R074.doc Copyright 2000 Kleinfelder, Inc.

These conclusions are subject to the limitations presented at the end of this report, and may change if additional information becomes available. Kleinfelder has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E 1527 and Union Bank of California's scope of work. Any exceptions to, or deletions from, this practice are described in Section 2.3 of this report. This work was authorized on May 30, 2000 (Log #E00-1148-T) and conducted in accordance with Kleinfelder's Master Service Agreement with Union Bank of California, dated February 22, 2000. 6.1 Identified On -site Issues Several recognized environmental conditions were identified in our review of the site, in particular, the former presence of the gasoline and fire service station from 1920 until about 1969. There is the potential that a UST(s) and a septic tank associated with this former business may still exist on the property. Furthermore, there is the potential for soil and groundwater contamination to be present from the former fueling operations and handling. Six drums of waste oil and a small quantity of paint and wax stripper remain in the rental I uilding. A 500-gallon diesel UST and a 5,000-gallon gasoline UST were removed from the equipment rental business in 1993, one of which was found to have released gasoline (although all soil contamination was reportedly excavated at the time of removal). Post -excavation soil samples indicated that the MTCA Method A cleanup levels were met. No evidence of the petroleum - impacted soil affecting the regional groundwater quality was reported. Petroleum impacted stock piled soils were transported off site to Roosevelt Regional Landfill for proper disposal. Various hazardous materials and waste oil containers were observed in the service bays during our site visit, and staining of the concrete floor was also observed in this area. Several runoff collection sumps were observed within the equipment servicing bays of the on -site structure, and in several areas in the lot immediately outside of the structure. One of the sumps within the service bay is in close proximity,to the area where hazardous materials and floor staining was observed. The integrity of the sumps and floor is suspect based on observed cracks in the 60-208101/6010R074.doc Page 19 of 23 Copyright 2000 Meinfelder, Inc. K L E I N F E 1. D E R 2405) 140111 Avt nue. NE.

There is the potential that petroleum products and other hazardous materials have been collected in the sumps and possibly released to the subsurface soils during the historical site operations. 6.2 Identified Off -site Issues Regarding potential off -site sources of impact, several sites were identified within the specified search distances in our review of regulatory -agency databases. Nearby USTs were also identified. In our opinion none of the identified sites are likely to have impacted the subject property. Furthermore, contamination from such offsite sources (if present) likely does not present an area -wide cleanup liability to the subject property due to Engrossed Senate Bill (ESB) 7900, which provides thAt the owner of a site that overlies a plume of contaminated groundwater I is not strictly liable for that contamination. 7.0 RECOMMENDATIONS We recommend Phase H investigations of the property to address the identified environmental conditions. Recommended investigations include: • Complete a geophysical survey of the site to further assess the potential presence of USTs or septic tanks on the subject property. • Complete subsurface soil and possibly groundwater sampling in areas adjacent to the two collection sumps and drum storage areas located in the service bay of the on -site. structure, in the location of the pump dispensers for the former gasoline stations, and in the location of the former gasoline and diesel tanks removed in 1993. • Remove and properly dispose of the drums of waste oil and paints remaining on site. • Complete a geophysical and possibly subsurface investigation of the concrete pad or patching observed in the asphalt parking lot located on the northwest side of the facility. • Complete a utility locate to confrim that the ofsite sumps are connected to the existing stormwater system. 60-208101/601 OR074.doc Copyright 2000 Kleinfelder, Inc.

The attached report is a qualitative assessment. Kleinfelder offers a range of investigative and engineering services to suit the needs of our clients, including more quantitative investigations. Although risk can never be eliminated, more detailed and extensive investigations yield more information, which may help to better understand and manage site risks. Since such detailed services involve greater expense, we ask our clients to participate in identifying the level of service that will provide them with an acceptable level of risk. Please contact the signatories of this report if you would like to discuss this issue of risk further..

Simons Site Assessor Nowicki & Associates Inc. 33516 9th Ave S Federal Way, WA 98003 Excutive Summary One approximately 5000 gallon gasoline storage tank and dispenser -were removed on 2/9/93 from the Federal Way Rental Mart Site. Contamination was found on top of the tank and on the west side of the tank. Tank and ' _ contamination were removed on the afternoon of 2/9/93. Lab analysis done on samples taken at the end of the day showed soils at the site to be below Model Toxic Control Act (MTCA) standards for a clean site. Fifty -yards of soil was stored next to the excavation site and lab analysis showed this soil to be contaminated. Lead analysis on stockpiled soil showed lead levels to be below MTCA cleanup levels. Light commercial uses are prevelant along Pacifice Highway. A junior high school is located directly behind the property. A warehouse shop is found to the south of Rental Mart. Accross the street to the east and up an 0 0 embankment are apartments which were built within the last fire years. Across Dash Point Road to the north is an abandonded service station(now a used car lot) which had its tanks and contamination removed within the last two years. Prior to the site's current use a fire shop was located on the property facing Pacific Highway. Enclosed is a site sketch showing a foundation and sewers from the former buildings. The gasoline tank removed was installed next to the septic tank and sewer from this demolished structure, Abandonded piping and a concrete pad were located a few feet west of the pump island. Upon excavation this piping appeared to have served an underground tank which had been removed many years ago. Probably this older tank had been in the same area as the present tank which was removed on 2/9/93. Tank installation wa's done just prior to 1970 which makes the installation approximately 25 years old. Cleaning and inerting of the tank was complete just after 10:00 AM. Representatives from the City of Federal Way Building Department and the local Fire District were onsite at this time to witness the inerting process. Asphalt was out around the outline of the proposed excavation, but upon actual excavation it was found that the dispenser was over the middle of the tank and the excavation was expanded to compensate. This top to the tank was exposed by about 11:00 AM. Contamination was evident around the plumbing and the top of the tank. Tank removal was accomplished just before 12:00. Tank condition was good with minimal corrosion and no visible holes. Contamination showed on the west side of the tank and flowed down the tank spreading to the west along the entire length of the tank. Dark grey soil with gasoline odor was excavated west about eight feet. A 4- inch sewer pipe connected to an approximately i 000 gallon septic tank was discovered during the excavation of contaminated soil. The sewer tank was located just to the northwest of the tank. North, south, and east sidewalls along with the bottom appeared to be clean. Excavation progressed west past the sewer pipe approximately eight feet along the entire length of the tank, A strong odor of organics or waste petroleum and solid grey soil was still noticeable on the west side of the excavation. Feld screening with the `tank Techtor was done with negative results. Sewer often _introduces an odor like .waste petroleum and this was later found to bye 'the case. At approximately 3:30PM samples were taken and sent to Spectra Labs of Tacoma, VITA for lab analysis. WTPH-G and BTEX were run on the five excavation samples following DOE Sampling guidelines. Sample results showed the excavation to be below Model Toxic Control Act'(MTCA) regulations for a clean site. Sample analysis done on the stockpile confirmed contamination by gasoline. Lead sample analysis was 74 PPM which is below the MICA cleanup level of 250 PPM. No groundwater was encountered during excavation. Approximately 50 yards of stockpiled soil was placed on 6 mil plastic and the pile covered with 6 mil plastic at the end of the work day. Closure of this site is recommended.

L The UST was decommissioned and excavated by O'Sullivan Petroleum Equipment Company (OPEC) of Seattle, Washington. Hazcon, Inc. (Hazcon) performed the UST k Site Assessment for the project following Washington State Department of Ecology's (Ecology) Guidelines for Site Checks and Site Assessments for USTs. L The objectives of this project included: ' L ■ Removing one 500 gallon diesel fuel UST and associated piping and pump island; +� Determining concentrations of diesel total. petroleum hydrocarbons (TPHs) in soil adjacent to and underlying the UST system and associated soil stockpile; • ,Compariilg concentrations of diesel TPHs detected in soil, if any, to the applicable Washington State Model Tcxics CvntroI Act (MTCA) Method A Soil Cleanup Guidelines (WAC 173-340) and Guidance for Rem' ediation of Releases from USTs;. and d ■ Interpreting field and analytical data, documenting field and UST removal activities, making recommendations for additional site characterization (if any), and preparing this report (following Washington State Department of Ecology's Guidance for Site Checks and Site Assessment for USTs). 0 Industrial Hlgiote S Sa fcty Smices • Asbestos Sunvy Ir Desisrt Smices Environmental Senires • Laboratory Serkiccs • TntininS Courses 0 1 ' L Page Two Rental Marts , L Locatlori The Rental Man is'located at 29805 Pacific Highway South, Federal Way, Washington, L (Section 4, Township 21 North, Range 4 East) (Figures 1 and 2). The subject property lies approximately one mile southeast of Poverty Bay and seen -tenths mile south of 2$$th Street, at an elevation of approximately 430 feet above sea level. The area immediately L adjacent to the subject property is predominately used for residential or light commercial purposes_ The subject property is operated•by Rental Marts for equipment rental. L The 500 gallon diesel fuel UST was located approximately 35 feet north of the west end of the Rental Mart facility (Figure 2). , L Letter Report Organization This letter report begins with a Summary of Findings, for this project. Following the L Summary of Findings is a discussion on project area geology and soil/groundwater conditions. Subsequent sections present other elements of Hazcon's UST Site Assessment investigation (UST history and decommissioning activities, excavation: descriptions; soil L sampling, laboratory analyses, findings, and conclusions). Figures and Tables accompanying this report follow the main text and are followed by the UST 30-Day Notice of Intent, UST is Closure, and UST Site Assessment Checklists (as filed with L Ecology). Stipporting technical appendices follow the UST Site Assessment Checklist: SUMMARY OF FINDINGS Diesel TPH concentrations detected in soil samples collected within the diesel fuel UST excavation ranged from non -detectable to 140 ppm (below MTCA Method A Soil Cleanup L Levels). The TPH concentration (as diesel and lubricating oil)- for one representative sample collected from the soil stockpile was 490 ppm (above the MTCA Cleanup Level). The soil stockpile classified as a Class III soil and was disposed of at the permitted .� Rabanco Landfill (by Rabanco) as a non -hazardous MTCA material: LOCAL GEOLOGY AND GROUNDWATER Local Geology L The geology in the vicinity of the subject property is dominated by Upper Pleistocene ground moraine deposits (Waldron, 1961) generally composed of thin ablation till overlying lodgment till (Mullineaux, 1965). Lodgement till is generally a compact, 1�a coherent, unsorted mixture: of sand, siIt, clay, and gravel; commonly termed hardpan. Ablation till is similar, but less compact and coherent. Lodgement till is practically I impermeable and relatively difficult to excavate and stable along steep exposures. 4 F Rental darts/Federal Way Xatcda, Inc. ■ Page Three Rental Marts ! Site Geology Soil within the UST excavation generally consisted of dry ' avely sands from the surface ! to a depth of 2 feet below ground surface (BGS), sandy fine gravel from 2 to 3 feet BGS, and moist gravely sands from 3 feet to -at least 8 feet BGS (Phota 11Appendix A). Groundwater Groundwater was not encountered in the UST excavation pit. UST HISTORY ' The 500-gallon diesel fuel UST and pump island dispenser were located 35 feet north of -the Rental Marts Facility (Figure 2).- According to Rental Mans the LIST and single pump J island dispenser where installed in about 1970. According to records on -file with the Washington State DOE UST Section, this UST was installed before•1955 (personal communication, Roger Nye). The UST was active until being decommissioned yn May J 21, 1993 (personal communication, Mike Muller, OPEC). The LIST system stored diesel fuel #2 during it's tenure and was used to refuel Rental Mart's rental equipment J The UST system consisted of a single -wall steel tank and associated steel piping. The UST was not anchored nor was it equipped with overfill or cathodic protection. The UST system check valve was located at the pump island dispenser and consisted of suction -type piping. OPEC is unaware of any volumetric tank tightness tests performed on the UST, The UST was inerted and excavated by OPEC on June 25, 1993. Prior to excavation the UST was triple rinsed and inerted with CO2 under OPEC's supervision. OPEC removed the UST from the excavation using a tire mounted backhoe. The tank showed minimal signs of rust and corrosion (e.g., pock marks) (Photo 2). OPEC transported the UST to Coastal Tank Inc. of Seattle, Washington for scrap metal (Appendix B). • EXCAVATION SITE DESCRIPTION - -� The UST was oriented rrorth-south. The removal of the UST; associated piping, ana the PUMP island dispenser (Photo 3) resulted in a single excavation pit (i.e., the pump island " and was located above the UK). J OPEC excavated the LIST system using a tire mounted backhoe. The UST system excavation pit was 13 feet by 8 feet in plan and had a depth of S feet BGS. Approximately 30 cubic yards of excavated soil was stockpiled adjacent to and west of the excavation pit (Figure 2). The soil stockpile was placed on and covered with visquene and bermed. The UST system excavation was surrounded with a chain link fence until site restoration. f Rentaf•Marts/Federal Way Xazeon, Inc. 1. Page Four Rental Marts SOIL SAMPLING . , Soil samples were selected by a Hazcon geologist (registered Site assessor with the Washington -State Department of Ecology), based on visual and olfactory observations. Hazcon collected a total of eight discrete soil samples from the UST excavation (five samples) and associated soil stockpile (three samples) (Figure 2). The five samples collected from the UST excavation pit included four samples from the excavation pit sidewalls (samples SW1-6.0, SW2-6.5, SW3-6.5, and SW4-7.0) and one from the excavation pit floor (sample B1-8.0). sidewall samples were collected between 6.0 feet and 7.0 feet BGS. The excavation pit floor sample was collected at .8-.0 feet BGS. Groundwater was fiat encountered the: UST excavation pit. Soil samples from the UST excavation were collected using the backhoe to withdraw soil from the excavation pit. An aliquot of soil was then _removed frotn'the center of the backhoe bucket using a stainless steel spoon and transferred to a preconditioned sterilized glass jar (soil sampling protocols,) Appendix C). Soil samples collected. from the soil stockpile were collected with a hand auger from the approximate soil stockpile center (samples STPI to STP3). Soil samples were placed in an ice chest and transported to the analytical laboratory. Chain of custody procedures were followed for all samples. LABORATORY ANALYSES Soil samples were analyzed for parameters outlined in Ecology's Guidancelbr Site Checks and Site Assessments for USTs (their Table 6-1. Required and Recommended Analyses for 1 Petroleum Substances). A total v£ five soil samples (two composite and three discrete soil samples) were analyzed for diesel TPHs by Friedman ,and Bruya Laboratories, Inc: of Seattle, Washington. Samples SW1-6.0 and SW3-65, (coIIected from the east and south sidewall respectively) were composited together into one sample for analysis (samples were composited together by the laboratory chemist). Samples SW2-6.5, SW4-7.0, and B1-8.0 (west sidewall, north sidewall, pit floor, respectively) were anal)red as discrete soil . samples. Soil stockpile samples STP1, SIF2, and STP3 were composited together into " one sample for analysis. A full laboratory report and a quality assurance review of the laboratory results are eyen in Appendix D. - FINDINGS Composite sidewall sample SWl-6.01SW3-6.5 hadtnon-detectable diesel TPHs (Table 1). Discrete sidewall samples SW2-5.5 and SW4-7.0 had a diesel TPH concentrations of 80 ppm and 140 ppm, respectively. Soil sample SW4-7.0 was collected from a narrow zone of soil contamination restricted to the northwest comer of the UST excavation (Photo 1). This soil sample was selected with the intent of representing a worst case scenario of contaminated soil within his narrow band. Discrete sample BI-8.0 had a diesel TPH concentration of 20 ppm. Soil stockpile composite sample (SI•P11STP21STP3) had a TPH ° (as a mixture of diesel and lubricating oil) concentration of 490 ppm (see Table 1/Appendix Rental MartslFederal Way Hazcon, Inca J J Page Five Rental MartA CONCLUSIONS All soil samples collected from within the UST excavation pit had diesel TPH concentrations below the MTCA Method A Cleanup Guidelines (200 ppm for diesel TPHs). Based on these results, further soil excavation was not required nor recommended.- Based on the TPH concentrations detected in the soil stockpile (490 ppm), the soil stockpile designated as a Class Ill• non -hazardous MTCA waste material. • According to Ms. Janice Dirnick, the petroleum contaminated soil stockpile was subsequently transported by Rabanco and disposed of at Rabanco's permitted landfill facility. The UST system excavation was backfilled with clean fill material to subgrade and finished with asphait under OPEC supervision.

The UST was decommissioned and excavated by O'Sullivan Petroleum Equipment Company (OPEC) of Seattle, Washington. Hazcon, Inc. (Hazcon) performed the UST Site Assessment for the project following Washington State Department of Ecology's (Ecology) Guidelines for Site Checks and Site Assessments for USTs. Ir The objectives of this project included: • Removing one 500 gallon diesel fuel UST and associated piping and pump island; ' . • Determining concentrations of diesel total petroleum hydrocarbons (TPHs) in soil adjacent to and underlying the UST system and associated soil stockpile; • Comparing concentrations of diesel TPHs detected in soil, ifany, to the applicable Washington State Model Toxics Control Act (MICA) Method A Soil Cleanup Guidelines (WAC 173-340) and Guidance for Rem' ediation of Releases from USTs;. and - • Interpreting field and analytical data, documenting field and UST removal activities, making recommendations for additional site characterization (if any), and preparing this report (following Washington State Department of Ecology's Guidance for Site Checks and Site Assessment for USTs). t Industrial Hygiene &Safety Services • Asbestos Survey & Design Services Emironmental Services • Laboratory SeA ices • Trainlylg Courses Page Two , Rental Marts Location The Rental Mart is located at 29805 Pacific Highway South, Federal Way, Washington, (Section 4, Township 21 North,'Range 4 East) (Figures 1 and 2). The subject -property lies approximately one mile southeast of Poverty Bay and seen -tenths mile south of 288th Street, at an elevation of approximately 430 feet above sea, level. The -area immediately adjacent io the subject property is predominately used for residential or light commercial purposes. The subject property is operated,by Rental Marts for equipment rental. The 500 gallon diesel fuel UST was located approximately 35 feet north of the west end of the Rental Mart facility (Figure 2). , Letter Report Organization, This letter report begins with a Summary of Findings for this project. Following the Summary of Findings is a discussion on project area geology and soil/groundwater conditions. Subsequent sections present other elements of Hazcon's UST Site Assessment investigation (UST history and decommissioning activities, excavation' descriptions; soil sampling, laboratory analyses, findings, and conclusions). Figures and Tables accompanying this report follow the main text and are followed by the UST 30-Day Notice of Intent, UST Permanent Closure, and US]' Site Assessment Checklists (as filed with Ecology). Supporting technical appendices follow the UST Site Assessment Checklist. SUMMARY OF FINDINGS Diesel TPH concentrations detected in soil samples collected within the diesel fuel UST excavation ranged from non -detectable to 140 ppm (below MTCA Method A Soil Cleanup Levels). The TPH concentration (as diesel and lubricating oil) for one representative sample collected from the soil stockpile was 490 ppm (above the MTCA Cleanup LeveI). The soil stockpile classified as a Class III soil and was disposed of at the permitted Rabanco Landfill (by Rabanco) as a non -hazardous MTCA material. LOCAL GEOLOGY AND GROUNDWATER Local Geology The geology in the vicinity of the subject property is dominated by Upper Pleistocene ground moraine deposits (Waldron, 1961) generally composed of thin ablation till overlying lodgment till (Mullineaux, 1965). Lodgement till is generaIIy a compact, coherent, unsorted mixture of sand, silt, clay, and gravel; commonly termed hardpan. Ablation till is similar, but less compact and coherent. Lodgement till is practically impermeable and relatively difficult to excavate and stable along steep exposures. Rental MartslFederal Way Hazcdn, Inc. Page Three Rental Marts Site Geology Soil within the UST excavation generally consisted of dry gravely sands from the surface to a depth of 2 feet below ground surface (BGS), sandy fine gravel from 2 tb 3 feet BGS, and moist &vely sands from 3 feet to at least 8 feet BGS (Photo 1JAppendix A). Groundwater Groundwater Groundwater was not encountered in the UST excavation pit. UST HISTORY The 500-gallon diesel fuel UST and pump island dispenser were located 35 feet north of -the Rental, Marts facility (Figure 2). According to Rental Marts the UST and single pump island dispenser where installed in about 1970. According, to records on -file with'the, Washington State DOE UST Section, this UST was installed before-1965 (personal, communication, Roger Nye), The UST was active until being decommissioned 4n May 21, 1993 (personal communication, Mike Muller, OPEC). The UST system stored diesel fuel #2 during it's tenure and was used to refuel Rental Mart's rental equipment. The UST system consisted of a single -wall steel tank and associated steel piping. The L]ST -was not anchored nor was it equipped with overfill or cathodic protection. -The UST system check valve was- located at the pump island dispenser and consisted of suction -type piping. OPEC is unaware of any volumetric tank tightness tests performed on the UST. The UST was-inerted and excavated by OPEC on June 25, 1993. Prior to excavation the UST was triple rinsed and inerted with CO2 under OPEC's supervision. OPEC removed the UST from the excavation using a tire mounted backhoe. The tank showed minimal signs of rust and corrosion (e.g., pock marks) (Photo 2). OPEC transported the UST to, Coastal Tank Inc. of Seattle, Washington for scrap metal (Appendix B). EXCAVATION SITE DESCRIPTION The UST was oriented north -south. The removal of the UST; associated piping, ana the pump island dispenser (Photo 3) resulted in a single excavation pit (i.e., the pump island and was located above the UST). OPEC excavated the UST system using a tire mounted backhoe. The UST system exdavation pit was 13 feet by 8 feet in plan and had a depth of 8 feet BGS. Approximately 30 cubic yards of excavated soil was stockpiled adjacent to and west of the excavation pit (Figure 2). The soil stockpile was placed on and covered with visquene and bermed. The UST system excavation was surrounded with a chain link fence until site restoration. Rents! MartslFederal Way Hazcon, Inc. i. Page Four Rental Marts SOIL SAMPLING Soil samples were selected by a Hazcon geologist (registered site assessor with the Washington State Department of Ecology), based on visual and olfactory_ observations. Hazcon collected a total of eight discrete soil samples. from the UST excavation (five samples) and associated soil stockpile (three samples) (Figure 2). The five samples collected. from the UST excavation pit included four samples from the excavation pit sidewalls (samples SW1-6.0, SW2-6.5, SW3-6.5, and SW4-7.0) and one from the excavation pit floor (sample B1-8.0). Sidewall samples were collected between 6.0 feet and 7.0 feet BGS. The excavation pit floor sample was collected, at 8.0 feet'BGS; Groundwater was not encountered the UST excavation pit.. Soil samples from the UST excavation were collected using the backhoe to withdraw soil from the excavation pit. An aliquot of soil was then.removed from the center of the backhoe bucket using a stainless steel sp6on and transferred to a preconditioned sterilized glass jar (soil sampling protocols,. Appendix C). Soil samples collected. from the soil stockpile were collected with a hand auger from the approximate soil stockpile center (samples STPI to STP3). Soil samples were placed in an ice chest and transported to the analytical laboratory. Chain of custody procedures were followed for all samples. LABORATORY ANALYSES Soil samples were analyzed for parameters outlined in Ecology's Guidance for Site Checks and Site Assessments for USTs (their Table 6-1. Required and Recommended Analyses for Petroleum Substances). A total of five soil samples (two composite and three discrete soil samples) were analyzed for diesel TPHs by Friedman .and Bruya Laboratories, Inc: of Seattle, Washington. Samples SW1-6.0 and SW3-6.5, (collected from the east and south sidewall respectively) were composited together into one sample for analysis (samples were composited together by the Iaboratory chemist). Samples SW2-6.5, SW4-7.0, and B1-8.0 (west sidewall, north sidewall, pit floor, respectively) were analysed as discrete soil samples. SoiI stockpile samples STP1, STP2, and.STP3 were composited together into one sample for analysis. - ' , , A full laboratory report and a quality assurance review of the laboratory results are given in Appendix D. , FINDINGS Composite sidewall sample SWI-6.0/SW3-6.5 had'non-detectable diesel TPHs (Table 1). Nscrete sidewall samples SW2-6.5 and SW4-7.0 had a diesel TPH concentrations of 80 ppm and 140 ppm, respectively. Soil sample SW4-7.0 was collected from a narrow zone of soil contamination restricted to the northwest comer of the UST excavation (Photo 1). This soil sample was selected with the intent of representing a worst case scenario of contaminated soil within this narrow band. Discrete sample B1-8.0 had a diesel TPH concentration of 20 ppm. Soil stockpile composite sample (STPI/STP2/STP3) had a TPH (as a mixture of diesel and lubricating oil) concentration of 490 ppm (see Table 1/Appendix D). Rental MarlslFederal Way Hazcon, Inc. Page Five Rental Marti CONCLUSIONS All soil samples collected from within the UST excavation pit had diesel TPH concentrations below the MTCA Method A Cleanup Guidelines (200 ppm for diesel TPHs). Based on -these results, further soil excavation was not required nor 44 recommended. Based on the TPH concentrations detected in the soil stockpile .(490 ppm), the soil stockpile designated as a Class. III -non -hazardous MICA waste material. • According to Ms. Janice Dimick, the petroleum contaminated soil stockpile was subsequently transported by Rabanco and disposed of at Rabanco's permitted landfill facility. The UST system excavation was bapkfilled with clean fill material to subgrade and finished with asphalt under OPEC supervision.

All samples were collected using standard sampling procedures which minimize the risk of sample contamination. Prior to soil sampling, sampling tools were cleaned with a stiff brush and detergent solution- consisting of Alconox and warm water, then rinsed with tap water and liberal quantities of distilled, deionized water. The soil samples were colleted in 4 ounce borosilicate glass containers with teflon- lined screw caps. Samples were stored in a chilled ice chest and delivered directly to Friedman and Bruya laboratories, Inc. of Seattle, Washington for analysis. Chain of custody forms accompanied each sample shipment, signed by field personnel, the shipping agency (i€ used), and the laboratory chemist. APPENDIX D Laboratory Report A 'Quality Assurance Data Review APPENDIX D LABORATORY REPORT & QUALITY ASSURRANCE REVIEW Analytical results were reported by the laboratory as a net weight value. The results shown in this report were converted to dry weight values by dividing the wet weight results by the percentage of -total solids in the -soil sample. , Laboratory quality assurance and quality control was performed by analyzing duplicate samples and surrogate recoveries. The duplicate sample results indicate good sampling and analytical precision. In general, all analytical data were deemed acceptable. FRIEDMAN & BRUYA, INC.

If you make changes or update the data, please use red (green, purple, orange etc) ink so data entry. folks can spot any changes quickly. 3. Complete the Environmental Indicators form (attached). The PREFERRED ALTERNATIVE is to use the Excel version in t:\tcp\vcp\review\forms\ ENVID.XIS and e-mail it to me. The guidelines for completing the form are in ENV_IND.DOC. 4. Return entire file to me when done. Remove all Post -it notes and markers from files. Include site logs, a signed copy of the determination letter (NFA or Further Action required), a copy of the recorded restrictive covenant, and all files. Please note the date you went on site by highlighting the date on your site log. Given the increasing frequency with which independent remedial action sites are the subject of litigation, with Ecology's decisions serving as the basis for some of it, I strongly suggest that you have your determination and correspondence peer -reviewed prior to sending it and that you document the basis of your decision with a brief memorandum to file. If you have any questions, please call me at 425-649-7023. If you have any suggestions regarding the process or paperwork that you think would make things easier, please let me hear them.

Independent Remedial Action Ruth Evans Trust, Federal Way, Washington Thank you for submitting the results of your independent remedial actions for review by the. State of Washington Department of Ecology (Ecology). Ecology appreciates your initiative in pursuing this administrative option under the Model Toxics Control Act (MTCA). Ecology's Toxics Cleanup Program has reviewed the following information regarding Ruth Evans Trust located at 29805 Pacific Highway South, Federal Way, WA: 1. "Phase I Environmental Site Assessment" by Kleinfelder Inc. dated June 13, 2000 2. "Report of Subsurface Investigation" by ATC Associates Inc. dated February 2, 2001 3. "Underground Storage Tank Site Assessment" by ATC Associates Inc. dated February 16, 2001 Ecology reviewed the information in the reports listed above and had a phone conversation with Mr. Mark Watts on May 17, 2001. Mr. Mark Watts indicated that the seasonal perched groundwater encountered during the excavation appears to be clean without oil sheen. He also indicated that the buried metal auto parts' debris had no evidence of any chemicals, including petroleum, impacts. Therefore, Ecology has determined that, at this time, the release of total petroleum hydrocarbons into the soil from the Underground Storage Tanks no longer poses a threat to human health or the environment. Therefore, Ecology is issuing this determination that no further remedial action is necessary at this site under MTCA, chapter 70.105D RCW. However, please note that because your actions were not conducted under a consent decree with Ecology, this letter is written pursuant to RCW 70.105D.030(1)(i) and does not constitute a settlement by the state under RCW 70.105D.040(4) and is not binding on Ecology. Ecology's no further action determination is made only with respect to the release identified in the report listed above. This no further action determination applies only to the area of the property affected by the release identified in the report at 29805 Pacific Highway South, Federal Page 2 Way, WA. It does not apply to any other release or potential release at the property, any other areas on the property, nor any other properties owned or operated by Ruth Evans Trust. Ecology will update its Leaking Underground Storage Tank database to reflect this "No Further Action" determination. Your site will not appear in future publications of the LUST database. The state, Ecology, and its officers and employees are immune from all liability and no cause of action of any nature may arise from any act or omission in providing this determination. If you have any questions, please contact Sunny Lin at (425) 649-7187. Sincerely, Sunny L' , P.E.

The inspection is scheduled for Tuesday April 2"d at 10:00 a.m. Shell Mini Mart 29625 Pacific Hwy S Federal Way Some owners hire their tank service provider to be present during the inspection to open all the necessary equipment. Some owners find it difficult to open the large metal manways above the turbines. Appropriate tools must be used to safely open and lift the heavy manways. Ecology inspectors will not open the equipment. Be sure you have the keys to open the dispenser panels and fill ports. , The Department of Ecology will require verification of paperwork (e.g., Master Business License, Insurance, testing) and access into the turbine sump and dispensers, so please have those items available at the time of the inspection.

See h_ttp://www.ecy.wa.gov/programs/tc_p/ust- lust/UST overview. df for more information. The inspection is scheduled for Tuesday January llet at 12:30 p.m. (+/- 'i hour) - located at: Shell Mini Mart 29625 Pacific Rwy'S Federal Way The Department of Ecology will require verification of paperwork (e.q., Master Business License, Insurance, testing) and access into the turbine sump and dispensers, so please have those items available at the time of the inspection. Please contact me at 425-649-7135 or cari461@e❑ .wa. ov if you have any questions regarding the upcoming inspection(s) or any of the enclosed information. Arthur Buchan is the Department of Ecology Inspector that will be performing your inspection; his phone number is 425-649-7149. Sincerely, Cathie Richardson Underground Tanks Case Developer Enclosure: Preparing for an Underground Storage Tank Inspection Focus on Preparing for an UST Inspection DEPARTMENT OF ECOLOGY state of Washington The Department of Ecology is required -to conduct an Underground Storage Tank (UST) Inspection at all registered tank sites to review records and equipment for compliance. What paperwork will be reviewed on -site? The paperwork reviewed depends on what type of system you operate. Have the following records, if applicable, available for review: ❑ Master Business License w/ tank endorsements ❑ Facility Compliance Tag ❑ Tank Pollution Liability Insurance or proof of self-insurance ❑ Tank Release Detection - Monthly printout (or log): ❑ Automatic Tank Gauge (ATG) 0.2 gph leak test passing results, or ❑ Interstitial (or an sensor normal results, or ❑ Statistical Inventory Reconciliation (SIR) results, or ❑ Daily/weekly/monthly sticking records (rare) ❑ Annual testing of sensors and ATG ❑ Pressurized Piping Release Detection ❑ Annual Test of Automatic Line Leak Detector (ALLD) And one of following choices ❑ Annual line tightness test, or ❑ Monthly printout (or log) of sump sensor normal results, or ❑ Monthly printout of 0.2 gph passing Electronic ALLD, or ❑ Monthly SIR results third party certified for lines ❑ Suction Piping with one check valve at pump (no release detection) ❑ Suction Piping with check valve at tank (choose one) ❑ Every 3 years line tightness test, or ❑ Monthly printout (or log) of sump sensor -normal results, or ❑ Monthly SIR results third party certified for lines ❑ Steel Tanks with Internal Lining Only (no cathodic protection): Internal Lining Inspection at 10 years and every 5 years thereafter ❑ Every 3 years Cathodic (Corrosion) Protection test ❑ Steel Tanks ❑ Steel Lines ❑ Turbine steel flex connectors in soil ❑ Under dispenser steel flex connectors in soil ❑ Every 60-day log of Volt/Amp readings for Impressed Current Systems What equipment needs to be opened? Depending on your type of system, you will need to open the following equipment: ❑ Large Metal Manway above Turbines ❑ Dispenser Panels ❑ Fills and Spill Buckets ❑ Overfill Equipment ❑ Automatic Shut -Off Valve, or ❑ -Ball-Float Device (opened w/tool), or ❑ Exterior Alarm Publication Number: 10-09-047 Should 1 hire my service provider to open the equipment? Some owners hire their tank service provider to be present during the inspection to open all the necessary equipment. Some owners find it difficult to open the large metal manways above the turbines. Appropriate tools must be used to safely open and lift the heavy manways. Ecology inspectors will not open the equipment. Be sure you have the keys to open the dispenser panels and fill ports. How many years of records will be checked? The regulation requires owners to keep release detection records for 5 years. Please have at least 12 months of records available for a detailed review on -site. The inspector will let you know if additional years of records will be checked. How often will each site be inspected? At least once during a three-year cycle each site will be inspected. How long is the inspection? On average one to two hours. They will be scheduled at least one week prior. The inspection needs your complete attention, so have someone else working as cashier. What if violations are found? The inspector may issue a Notice of Non -Compliance, which outlines actions you need to take with deadlines to achieve compliance. Significant violations may result in a Field Penalty being issued on -site. If compliance is not achieved or there are severe violations, Ecology may pursue formal enforcement action. What if my tank is temporarily closed? Corrosion protection must be operational and testing conducted, if applicable, during temporary closure. If your tank has less than an inch of product, no release detection is necessary, but you will need to stick the tank during the inspection to verify. If your,tank has product in it, you need to be conducting release detection. All other records will be reviewed and equipment checked. How does the inspection benefit me? Failure to properly operate and maintain your UST system equipment may result in a significant loss in your property investment and contaminate the environment. Correct operation and maintenance help ensure that leaks are detected early or even prevented, protecting your investment and potentially saving you thousands of dollars in cleanup costs. Further. questions? Please contact your regional office below and ask for a tank inspector to assist you.

The subject site is currently listed on the Leaking Underground Storage Tank database. Site Description The subject site is located at 29625 Pacific Highway South in Federal Way, King County, Washington (Section 4, Township 21 North, Range 4 East, WM). The subject site is an irregular shaped property consisting of one tax parcel, totaling approximately 0.96 acres in size. The site currently supports a gasoline station and convenience store and associated fueling system. The building is located in the north central portion of the property (see Figure 3 — Site Plan). The current site building was reportedly built in 1995. According to the United States Geological Survey (USGS) 7.5-minute series topographic map, "Poverty Bay" (1961 Photo revised 1994), elevation of the site is approximately 420 feet above sea level. Topographically, the building area of the subject site is generally level. The paved areas have been graded to drain to a series of catch basins. A steep slope is present adjacent to the north of the building that slopes down to drainage area at the northern property line. Regional gradient general slopes moderately down to the west/northwest to Poverty Bay. C. LSI - Adapt The subject site is bordered to the north by undeveloped woodland; to the east by Pacific Highway, beyond which is an apartment complex; to the south by Dash Point Road, beyond which is a vacant commercial building and storage yard; and to the east by Redondo Way South, beyond which are a veterinary cliniclanimal hospital and retail businesses. An athletic field/recreation area is present to the southwest across the intersection of Dash Point Road and Redondo Way. Project Background i The following project history and background is a summary from information presented in several previous reports including four subsurface investigations or remedial actions and two Phase I Environmental Site Assessments. Three of the subsurface reports were prepared by GeoEngineers, Inc. (GeoEngineers) and submitted to Ecology in 1989 and 1991. The fourth subsurface report was prepared by Assessment and Remediation Consulting Services (ARCS) ' and has not been submitted to Ecology. The three GeoEngineers reports are titled "Report of Remedial Action Underground Storage Tank Removal, UNOCAL Service Station 6227°, dated November 27, 1989, "Results of Supplemental Field Testing UNOCAL Service Station 6227" j Dated .January 17, 1991 and "Report of Remedial Action Underground Storage Tank Removal, UNOCAL_ Service Station 6227" dated April 10, 1991. The ARCS report is titled "Letter Report - Limited Phase II Investigation, Shell Service Station and Mini -Mart" dated April 9, 2001. The two Phase I reports were prepared by Adapt and dated October 17, 2005 and ARCS dated December 1, 2000. Copies of the GeoEngineers and the Limited Phase II prepared by ARCS -` reports are attached in Appendix Cr D. E and F. Site History r-- The subject site was developed with a store and two sheds/garages prior to 1936 until approximately 1969. The subject site was developed with a UNOCAL gasoline service station L in 1970. The service station reportedly operated from approximately 1970 until the late 1980s. The steel underground storage tanks (USTs) associated with the 1970 UNOCAL service station were reportedly removed in 1989 and replaced with new fiberglass USTs in 1989. The 1989 USTs were reportedly removed in 1990191 and were not replaced. The site was reportedly occupied by an automobile sales facility and U-Haul Company during the early 1990s. The 1970 UNOCAL gasoline service station building was reportedly demolished in 1994195. The current underground storage tanks and fueling system were reportedly installed in 1994 as part of the construction for the existing convenience store which was reportedly built in 1995. The 1970 era gasoline service station was operated by Union Oil from 1970 until late 1980s/early 1990s. The current gasoline station is a Shell branded station. USTs removal activities in both 1989 and 1990/91 documented petroleum impacts to soil beneath the USTs and former station building. According to the UST removal reports prepared by GeoEngineers and summarized below, approximately 800 to 900 cubic yards of petroleum impacted soil were excavated and transported off site for disposal in 1989 and 1991. Federal Way Deli Mart-NFA Request Letter November 23, 2 LSI Adapt Project No. WA05-13165-ESA Page November 2 2 LSI - Adapt Previous Characterization and Remedial Work "Report of Remedial Action Underground Storage Tank Removal, UNOCAL Service Station 6227". dated November 27, 1989 Report Summary According to the GeoEngineers 1989 UST removal report, two 10,000-gallon gasoline; one 550- gallon waste oil and one-550-gallon heating oil USTs were removed from the subject site in September 1989. GeoEngineers documented petroleum impacts to soil beneath the gasoline and waste oil USTs. Analytical results from soil samples are summarized in Table 1 attached in Appendix A. According to the report approximately 600 cubic yards of petroleum impacted soil was removed from beneath the gasoline USTs and 100 cubic yards of petroleum impacted soil was removed from beneath and in the vicinity of the former waste oil UST. GeoEngineers collected confirmation soil samples from the lateral and vertical extent of the excavations. Analytical results from soil samples collected from beneath and from the sidewalls of the gasoline USTs excavation did not identify petroleum impacts above regulatory cleanup levels in place in 1989. Confirmation sampling beneath and in the sidewalls of the former waste oil UST documented 14,933 parts per million [ppm] Total Petroleum Hydrocarbons [TPH] in north sidewall, adjacent to the former building and 208 ppm TPH in the bottom of the excavation at approximately 8.5 feet. Reported concentrations at the bottom of excavation were above cleanup levels in place in 1989 but would be below current cleanup levels for dieseVoil. The documented concentrations in the north sidewall exceed both previous and current cleanup levels. Analytical testing of the waste •oil UST included testing. for halogenated (chlorinated) volatile compounds and did not document any halogenated compounds above laboratory reporting limits. The GeoEngineers UST removal report concluded that to remove the documented contamination in the north wall of the waste oil UST the service station building would have to be removed. They also concluded that the extent of the impacted soil in the vicinity of the waste oil UST was of limited extent. "It is our opinion therefore, that this contamination does not represent a hazard to human health or the environment and that removal of the building is not warranted." The GeoEngineers report stated that three new USTs (two 12,000-gallon gasoline and one 520- gallon waste oil) were installed in the former gasoline and waste oil UST excavations in 1989. "Results of Supplemental Field Testing UNOCAL Service Station 6227" Dated January 17, 1991 Report Summary According to the GeoEngineers 1991 Supplemental Field Testing report one boring/vapor well was installed in August 1990, west and slightly south of the former waste oil UST to document conditions in the vicinity of the former waste oil and heating oil USTs and to assess whether shallow groundwater exists beneath the subject site. The vapor well was reportedly advance to a total depth of 33 feet below ground surface. The report stated that the upper 25 feet was fill material "consisting of sand and gravel with variable amounts of silt." The lower 8 feet of the vapor well was reportedly very dense native soils. GeoEngineers documented a slight sheen on soil from 17 to 23 feet below ground surface and a TPH concentration of 420 ppm in a soil sample from approximately 23 feet bgs using EPA Method TPH 418.1. This reported level was Federal Way Deli Mart-NFA Request Letter November 23, 2005 LSI Adapt Project No. WA05-13165-ESA Page 3 LSI - Adapt above the cleanup levels in effect in 1990 but below current cleanup levels for diesel and/or heavy oil. GeoEngineers recommended that based on their findings from the vapor well boring and their previous the November 1989 UST removal report that additional soil be excavated (' from the waste oil UST location and that exploratory excavations be completed in the vicinity of the vapor well to identify the extent of petroleum impacted soil documented in the vapor well boring. "Report of Remedial Action Underground Storage Tank Removal, UNOCAL Service Station 6227' dated April 10, 1991 Report Summary ( The three fiberglass USTs that were installed in 1989 were reportedly removed from the subject `- site in December 1990 and January 1991. Analytical results from soil samples collected from the bottom and sidewalls of the gasoline UST excavation reportedly did not document petroleum contamination. However, elevated levels of lead (460 ppm and 770 ppm) were identified in soil samples collected from the bottom of the gasoline UST excavation. Petroleum impacted soil was documented in both the waste oil UST (TPH at 210 ppm from a bottom sample) and product line (Gasoline at 110 ppm from product line trench) excavations at levels above regulatory cleanup levels in effect in 1991. Approximately 110 cubic yards of soil were reportedly excavated from the gasoline, waste oil and product line excavations and transported I off site for disposal at an approved facility. Confirmation soil samples collected by GeoEngineers from the bottom and sidewalls of the gasoline LISTS, the waste oil UST and the product line excavations did not document petroleum hydrocarbons or lead above laboratory reporting limits or regulatory cleanup levels in effect in 1991. Analytical results are summarized I in Table 1 attached in Appendix A. i The report indicated that approximately 180 cubic yards of soil was excavated from the vicinity of the vapor well installed in August 1990 to a depth of approximately 18 feet bgs. The analytical results for soil samples collected from the vapor well excavation did not document petroleum hydrocarbons above 1991 cleanup levels except one sample at approximately 16 feet bgs. A deeper sample from approximately 18 feet bgs reportedly did not exhibit petroleum hydrocarbons above 1991 cleanup levels. Based on the findings, GeoEngineers concluded "As indicated in previous reports, the service station facilities are constructed on imported till placed at the head of a ravine. It is possible that the concentrations of TPH detected in soil samples from the vapor well excavation and the sample obtained from a depth of 23 feet in the vapor well boring are the result of interferences caused by organic matter present in the imported fill. /n our opinion, petroleum -related contamination of regulatory significance is not present in the location of the former vapor well at this site." "Letter Report -Limited Phase 11 Investigation, Shell Service Station and Mini -Mart" dated April 9, 2001 Report Summary ARCS conducted a Limited Phase II Investigation at the existing Shell Station and Mini -Mart. According to the report, four soil borings were, advanced at the subject site using direct -push drilling method. Borings were located to the north of the existing USTs and to the southwest of the western dispenser island. A fourth boring was located at the base of the slope to the north of the subject site building adjacent to a drainage bioswale. The borings were advanced to between 9 and 18 feet below ground surface. The ground surface adjacent to the bioswale is Federal Way Deli Mart-NFA Request Letter November 23, 20e5 LSI Adapt Project No. WAe5-13165-ESA Page 4 LSI - Adapt reportedly approximately 15 to 20 feet below the ground surface of the site building and parking areas. ARCS stated that "no staining or fuel -type odors were observed in the soils recovered from the borings." According to the ARCS report analytical results did not exhibit petroleum hydrocarbons above the laboratory reporting limits. The ARCS report concluded that "Based on field observations and laboratory data, there are no obvious indications of a release at this site. At this time, no additional investigation activities are recommended." Site Closure F-I Data collected during the 1989 and 1990/91 UST removal, remedial and 2001 characterization studies conducted by GeoEngineers and ARCS show that current soil conditions beneath the subject site meet current MTCA Method A Cleanup levels for lead, TPH-GJBTEX and TPH-D/n. Vertical and lateral confirmatory soil samples collected from the bottoms and from sidewalls of the excavations for the former gasoline and waste oil USTs did not document TPH-G/BTEX and TPH-D/a above current MTCA Method A cleanup levels. Vertical and lateral confirmatory soil l- samples from the vapor well excavation indicate that the residual TPH-D/O impacted soils in the l vicinity of the former vapor well, are below current MTCA Method A Cleanup levels. Groundwater was not been encountered in any of the borings to maximum depth of 33 feet below ground surface or in any of the excavations to depths of 18 feet below ground surface. Further, the analytical results from the bottom of the excavations, and the exploratory borings indicate that any soils with residual petroleum compounds are below current MTCA Method A Cleanup levels and are protective of groundwater. The three GeoEngineers reports were submitted to the Toxics Clean-up Program at Ecology for review and comment in 1989 and 1991- The reports were reviewed by Mr. Joseph Hickey of the Toxics Cleanup Program. Mr. Hickey issued a letter dated April 22, 1991 that indicated concurrence with the GeoEngineers conclusion from the 1991 UST removal report which stated that "in our opinion, petroleum -related contamination of regulatory significance is not present in the location of the former vapor well at this site." However, the site owners did not officially request a No Further Action determination in 1991 and the April 22, 1991 letter does not appear to be a determination of no further action letter and the subject site is still listed on the LUST database as reported cleaned up. As such, Adapt, on behalf of Mr. Hart Yung Ho, requests that Ecology issue a determination of No Further Action and that the site be removed from Ecology's Leaking Underground Storage Tank database.

Two 10,000-gallon steel gasoline storage tanks, one 550-gallon steel waste oil tank and one 550-gallon steel heating oil tank were removed from the site between September 12 and 14, 1989. The steel -gasoline storage tanks were replaced by two 12,000-gallon double -wall fiberglass -coated steel replaced with a underground storage tanks. The steel waste o t il ta nk The ssteel heating oil 520-gallon double -wall fiberglass -coated*steel tank was removed but not replaced. The purpose of our services was to observe and evaluate subsurface soil conditions .in the excavations, and to develop a remediation plan, if necessary. GeoEngineers' scope of services completed for this project is listed below. 1. Observe and document the excavation of the four underground storage tanks at the site. 2. Obtain soil samples from the limits of the storage tank excava- tions -for chemical analysis of petroleum -related contaminants. Field screening was conducted on each soil sample forevidence contamination using visual, water sheen and volatile organics headspace screening methods. These methods are described in Appendix A. 3. Obtain one soil sample for chemical analysis from beneath a segment of the product lines that was exposed during repair of a broken water line. 0 �i I On Geo P!Engineers Obtain composite samples for chemical analyses from soil removed from the excavations as required for disposal at a landfill. Evaluate the field and laboratory data with regard to existing regulatory concerns. 4. 4 SOIL EXCAVATION AND SAMPLING GASOLINE STORAGE TANK EXCAVATION Joe Hall Construction Inc. (Joe Hall) removed the two gasoline storage tanks on September 12, 1989 from the locations shown in Figure 2. GeoEngineers was present to observe the tank removal activities and to obtain soil samples. .Very minor evidence of rust and corrosion was observed on the two storage tanks. Ground water was not encountered in the excavation. The excavation extended to a depth of 18 feet in the southern portion and 19 feet in the northern portion. Backfill surrounding the tanks consisted of sandy gravel. Fine to medium gravelly sand interbedded with thin layers of gravel and cobbles was encountered in the walls of the gasoline tank excavation to a depth of 18 feet. The gravelly sand unit is underlain by silty sand with occasional gravel. Physical evidence of petroleum -related contamination was detected in the backfill material in the vicinity of the fill port for the super unleaded gasoline storage tank. Approximately 600 cubic yards of contam- inated backfill was transported to Fife Sand and Gravel for aeration. Non - contaminated backfill was transported to Fife Sand and Gravel for use as fill material at other locations. The excavation was lengthened on September 12 to accommodate the larger gasoline storage tanks. The* final limits of the excavation are shown in Figure 2. Seven soil samples (Samples 3 through 9) were obtained from the limits of the completed excavation. Sample 1 was obtained -from the non - contaminated backfill removed from the tank excavation ,and Sample 2 was collected from the contaminated backfill that was transported to Fife Sand and Gravel. All of these soil samples were analyzed for the presence of total petroleum hydrocarbons (TPH by EPA Method 419.1) and for benzene, ethylbenzene, toluene and xylenes (BETX by EPA Method 8020).

SOIL DISPOSAL We were informed by Joe Hall Construction that the 700 cubic yards of soil temporarily stored at Fife Sand and Gravel was transported on November 21, 1989 to Coal Creek Landfill for disposal. Del Lovell of Joe - Hall Construction indicated that permission for disposal was given by Seattle -King County. Department of Public Health based on the results of chemical analyses on samples of the soil removed from Service Station 6227. CONCLUSIONS AND RECOMMNDATIONS Based on the results of our observations and testing, gasoline -related contamination of regulatory significance is not present in the vicinity of the underground gasoline storage tanks. However, the results of this study indicate the presence of subsurface petroleum -related soil contamination in the vicinity of the new waste oil tank. Excavation of this soil would require removal of the service station building and the new tank. The residual contamination in the vicinity of the waste oil tank appears to be limited in extent. It is our opinion, therefore, that this 4 -�� Geo 'c Engineers contamination does not represent a hazard to human health or the environment [� and that removal of the building is not warranted.

A - 1 �1 Geotiffl-E igineers Headspace vapor screening involves placing a soil sample in a plastic sample bag. Air is captured in the bag and the bag is shaken to expose the soil to the air trapped in the bag. The probe of a Bacharach TLV Sniffer is used to puncture the bag, the instrument withdraws the air in the bag and the TLV Sniffer records the concentration of combustible vapor- in the air removed from the sample headspace. The TLV Sniffer records concentrations in parts per million (ppm) and is calibrated to hexane. The Sniffer is designed to quantify combustible gas concentrations in the range between 100 and 10,000 ppm. Field screening results are site specific. The results vary with temperature, soil type, type of contaminant, and soil moisture content. CHEMICAL ANALYTICAL PROGRAM Soil samples obtained between September 12 and 14, 1989 were analyzed by Enviros Corporation or Sound Analytical Services, Inc.. The soil samples were analyzed for TPH and/or BETX. Infrared spectrophotometry methods were used to analyze for petroleum hydrocarbons (EPA Method 418.1) and gas chromatography was used to quantify BETX (EPA Method 8020). The composite sample obtained from backfill material surrounding the gasoline tanks was also analyzed for- fuel hydrocarbons by. modified EPA Method 8015. The composite sample obtained from backfill material surrounding the heating oil and waste oil tanks was analyzed for PCBs, chlorinated hydrocarbons (EPA Method 8010), and TPH (EPA Method 418.1).

The site is located northwest of the intersection between Pacific Highway South and Dash Point Road in the Federal Way area of King County, Washington. The site location and surrounding features are shown in Figure 1. The general layout of the site is shown on the Site Plan, Figure 2. GeoEngineers previously completed two studies at Service Station 6227. We provided geotecbnical services regarding fill embankment and storm drain replacement in 1987. The results of our geotechnical consultation are presented in our .report dated June 4, 1987. We observed the removal of the former underground gasoline, waste oil and heating oil storage tanks at the site in September 1989. The results of our observations during tank removal activities at the site are presented in our report dated November 27, 1989. Total petroleum hydrocarbons (TPH) were detected at concentrations greater than the Washington Department of Ecology (Ecology) cleanup guidelines in the walls and base of the excavation completed for removal of the waste oil and heating oil tanks in 1989.- The excavation was between the service station building and the southern service island (Figure 2). Removal of all the contaminated soil from this area was not attempted because of the potential for endangering the building.and service island concrete slab. The former gasoline and waste oil tanks were replaced with new tanks. The heating oil tank was removed, but not replaced.

SITE CONDITIONS GENERAL y limits in Service Station 6227 is located within the t. Federal t Way located at the _ an area of primarily residential develop head of a ravine that slopes steeply downward toward concretes nor and slopes tgently The surface of the site is paved with asphaltic downward toward the northwest. The elevation of the site is approximately 420 feet above sea level. The service station is inactive. The property includes a service e islands, two 12,000-gallon station building, three covered servic GeO%@Engineers Unocal January 17, 1991 Page,3 underground gasoline storage tanks and one 520-gallon underground waste oil .tank. These tanks were installed at the site in 1989. The locations of the current facilities at the service station are shown in Figure 2. SUBSURFACE SOIL CONDITIONS the vicinity of the former waste oil and Subsurface soil conditions in heating oil tanks were explored by drilling one exploration boring (VP-1) at the location indicated in Figure 2. Details of the field exploration program and the boring log are presented in Appendix A. Based on the results of our earlier geotechnical study, we understand that the service station is constructed on imported fill placed at the head of the ravine. Fill consisting of sand and gravel with variable amounts of silt was encountered from the base of the asphalt paving to a depth of 25 feet in VP-l. Very dense silty sand with gravel grading to gravel with sand and silt (glacial till) was encountered beneath the fill to the total depth of the boring (33 feet). GROUND WATER CONDITIONS Ground water conditions were explored by installing a vapor probe well casing in Boring VP-1. Construction details, for the vapor probe are included in Appendix A. Ground water was not encountered in the boring. Based on the geology of the area, we anticipate that the depth to ground water at this site is greater than 100 feet. It is possible that runoff water from higher ground east and south of the site drains down the filled ravine during rainy months of the year. "Perched" ground water may exist seasonally above the glacial till unit. SUBSURFACE CONTAMINATION Potential subsurface petroleum -related contamination at the location f VP-1 was evaluated by: (1) conducting field screening on soil samples o the boring for evidence of contamination using visual, water sheen and headspace vapor screening methods, and (2) testing one soil sample from the boring for BETX and TPH. The subsurface soil analytical data are summarized in Table 1. The field screening results are presented on the boring log. The laboratory report is included in Appendix B. Geok Engineers Unocal January 17, 1991 Page 4 A slight sheen was observed on the soil samples obtained from the depths of 17 and 23 feet in VP-l. Headspace vapor concentrations were less than 100 parts per million (ppm) for all of the soil samples from VP-1. The soil sample from a depth of 23 feet was tested for BET% and TPH. BETX was not detected. TPH was detected at a concentration of 420 milligrams per kilogram (mg/kg) in this 'sample. Mr. Joe Hickey of Ecology was informed on August 31, 1990 of the presence of the subsurface soil contamination detected in VP-l. Mr. Hickey also has a copy of our report dated November 27, 1989, regarding our observations during tank removal at the site. CONCLUSIONS AND RECDIMNDATIONS The results of this study indicate the possible presence of petroleum - related contamination at depth beneath the site of Service Station 6227. The concentration of TPH detected in the soil sample obtained from 23 feet in VP-1 (420 mg/kg) exceeds the current Ecology soil cleanup guideline for TPH of 200 mg/kg. Three soil samples obtained from the limits of the heating oil and waste oil tank excavation in 1989 also exceeded Ecology's cleanup guideline for TPH. We drilled VP-1 in an attempt to determine whether shallow or "perched" ground water is present beneath the service station site. Because of the variable geologic conditions beneath the site, the results of this effort are inconclusive. We understand that Unocal intends to remove the existing gasoline and waste oil tanks from the site in the near future. We recommend that additional soil be excavated from the location of the former waste oil and heating oil tank excavation. Soil should be removed from this area until the concentrations of petroleum -related contamination are less than Ecology cleanup guidelines. It may be necessary to demolish the service station building and a portion of the southern service island to excavate all of the contaminated soil. We further recommend that an exploratory excavation be completed in the vicinity of VP-1 to determine the extent of the subsurface contamination detected in this boring. The depth of this excavation will be approximately 25 feet. It may be necessary to extend this excavation in the .direction of the service station building if subsurface conditions suggest that the J. Geoj%p Engineers Unocal 1991 January 17, Page 5 ce of contamination in Vp-1 is the waste oil tank or a source beneath sour exploratory excavation the building. Soil samples obtained from the rbn bshould A be submitted for laboratory analysis of petroleum hydrocarbons Y Methods 8015 (modified) and 418.1. We understand that the storm drain that was replaced in 1987 was installed around the western perimeter of the site. If the storm drain is encountered during excavation it may be necessary to temporarily remove a portion of the drain pipe to allow excavation to continue. The storm drain should be fully restored upon completion of work at the site. We recommend that contaminated -soil be treated on the site if feasible. In our opinion, land farming/biological treatment is the most practical consist of method of soil remediation at this site. of the n should tilling the spreading the soil on a lined and bermed area property, izer) and water as necessary to soil regularly, and adding nutrients (fertil promote biodegradation of the petroleum product. LIMITATIONS We have prepared this report for use by Unocal. This report can be made available to prospective buyers of the property and to regulatory agencies. The report is not intended for use by others and the information contained herein is not applicable to other sites. Our interpretations of subsurface conditions are based on data from one boring and from previous excavations at the site. It is possible that areas with undetected contamination exist in areas of the site that were not explored or analyzed. - 0 0 0 - @_ Geo� Engineers Unocal January 17, 1991 Page 6 Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time the report was prepared.

CHEMICAL ANALYTICAL• DATA B=1 through B-140 i Geo � - ngineers REPORT OF REMEDIAL ACTION UNDERGROUND STORAGE TANK REMOVAL UNOCAL SERVICE STATION 6227 KING COUNTY, WAS HINGTON FOR UNOCAL INTRODUCTION AND SCOPE This report summarizes the results of GeoEngineers' observations during the removal of the underground storage tanks at the site of Unocal Service Station 6227 near Federal Way in King County, Washington. The site is located northwest of the intersection between Pacific Highway South and Dash Point Road, as shown in Figure 1. The general layout of the site is shown in Figure 2. The storage tanks were removed from the site during December 1990 and January 1991. The tanks removed during this study were installed at the site in September 1989. GeoEngineers previously completed three studies at the site. We provided geotechnical services regarding fill embankment and storm drain replacement in 1987. The results of our geotechnical consultation are presented in our report dated June 4, 1987. We observed the removal of the former underground gasoline, waste oil and heating oil tanks in September 1989. The results of our observations during removal of the former tanks are presented in our report dated November 27, 1989. We drilled one exploration boring and installed a vapor well casing (VP-1) in the boring during July 1990. The results of our vapor well exploration are presented in our report dated January 17, 1991. Information provided by Unocal indicates that the service station facilities were constructed in 1969. A survey completed in February 1969 indicates that the site was covered primarily with vegetation prior to construction of the service station facilities. Two frame buildings were located in the southwest corner of the site in February 1969. We understand that the underground storage tanks removed from the site during 1989 were the tanks installed originally in 1969. Two 12,000-gallon double -wall, fiberglass -coated steel gasoline storage tanks; associated product lines; one 520-gallon double -wall, fiberglass - coated steel waste oil tank; and the vapor well were removed from the site between December 13, 1990 and January 10, 1991. The underground storage tanks, product lines and vapor well were not replaced. i Geo a ngineers 1_ The purpose of our services was to observe and evaluate subsurface soil s conditions in the excavations and to evaluate the need for remedial actions at the site. GeoEngineers' scope of services completed for this project is listed below. IJ1. Observe and document the excavation and removal of the underground storage tanks, product lines and vapor well at the site. f 2. Obtain soil samples from the limits of the excavations and from soil stockpiles for chemical analysis of petroleum -related contaminants. Conduct field screening on each soil sample for evidence of contamination using visual, dater sheen and headspace vapor screening methods. Field screening methods are described in Appendix A. 3. Submit selected soil samples from the excavations and soil stockpiles for one or more of the following chemical analyses: TPH (total petroleum hydrocarbons) by EPA Method 418.1; fuel I hydrocarbons by modified EPA Method 8015; BETX (benzene, ethylben- { zene, toluene, xylenes) by EPA Method 8020; lead by EPA Method 7420; and TCLP.(toxicity characteristic leaching procedure) metals by EPA 7000 series methodology. 4. Evaluate the field and laboratory data with regard to existing r, regulatory concerns. !.� 5. Arrange for disposal of soil with petroleum -related contamination at the Kitsap County Landfill. SOIL EXCAVATION AND SAMPLING GENERAL i Sleister (A.L. Sleister and Sons Construction, Inc.) excavated and removed the underground storage tanks, product lines and vapor well at the site. Sleister was also responsible for the excavation of petroleum - contaminated soil encountered at the site. A representative. of GeoEngineers was present to observe the tank removal and soil excavation activities, and ito obtain soil samples from the excavations. Soil removed from the excavations was placed in temporary on -site stockpiles. The stockpiles were segregated according to the source of the soil and the relative degree of contamination based on field screening. Composite soil samples were i collected from each individual stockpile. s 2 i_ Geo ngineers The former locations of the underground storage tanks and the vapor i well, the limits of the excavations and the soil sample locations are shown _ in Figure 2. The soil sample analytical data are summarized in Tables 1, 2 and 3. Laboratory data sheets and chain -of -custody records are included in Appendix B. of Ecology) Ecology (Washington State Department gy) has established soil Li cleanup levels under MTCA (Model Toxics Control Act). The MTCA Method A i soil cleanup levels for petroleum -related contamination are listed below. �) Compound MTCA Cleanup Level L� Benzene 0.5 mg/kg i Ethylbenzene 20 mg/kg f Toluene 40 mg/kg Xylenes 20 mg/kg TPH (quantified as gasoline) 100 mg/kg TPH (quantified as diesel) 200 mg/kg 1 TPH (other) 200 mg/kg Total Lead 250 mg/kg Note: mg/kg a milligrams per kilogram. �.1 WASTE OIL TANK EXCAVATION The waste oil tank was removed on December 13, 1990. Corrosion or pitting were not observed on the tank. Backfill surrounding the tank consisted of fine to medium sand. Soil encountered in the walls and base of the excavation consisted of gravelly sand with thin layers of gravel and cobbles. Ground water was not encountered in the excavation. Seven discrete soil samples (WO-1 through WO-7) were obtained from the limits of the waste oil tank excavation on December 13, 1990. One sample (WO-8 composite) was obtained from the stockpiled soil on December 13, 1990. The soil samples obtained from the waste oil tank excavation limits and soil stockpile were submitted for chemical analysis of TPH and fuel hydrocarbons. 3 Geo ngineers The sample obtained from the soil stockpile was also analyzed for TCLP metals. Soil sample analytical results are summarized in Table 1. Soil �- sample locations are shown in Figure 2. The concentration of TPH (210 mg/kg) exceeded the MICA cleanup level in sample WO-1 obtained from the base of the excavation. Fuel hydrocarbons were not detected in sample WO-1. TPH and fuel hydrocarbons were either not Ell detected or were detected at concentrations less than MTCA cleanup levels in the remaining samples. Additional soil was removed from the waste oil tank excavation on December 31, 1990. Sample WO-8 (a discrete sample) was ! obtained from the base of the excavation after the additional soil was removed and submitted for chemical analysis of TPH and fuel hydrocarbons. TPH and fuel hydrocarbons either were not detected or were detected at concentrations less than MICA cleanup levels in sample WO-8. �J GASOLINE TANK EXCAVATION The gasoline storage tanks were removed on December 18, 1990. Corrosion or pitting were not observed on the two gasoline tanks. Remedial activities at the site were suspended between December 19 and 30, 1990, because of weather conditions. { Backfill surrounding the tanks consisted of fine to medium sand. Fine to medium gravelly sand with thin layers of gravel and cobbles was ' encountered in the walls and base of the gasoline tank excavation. Evidence of petroleum -related contamination was not observed in the tank backfill or r in the walls and base of the excavation. Ground water was not encountered i in the excavation. Five discrete soil samples (G-1 through G-5) were obtained from the f limits of the excavation on December 31, 1990. Four composite samples (SP-1, SP-2, G-SP-A and G-SP-B) were obtained from the stockpiled soil. The soil samples were analyzed for BETX and fuel hydrocarbons. All of the samples, excluding composite samples SP-2 and.G-SP-A, were also submitted for analysis of total lead. Soil sample analytical results are summarized in Table 2. Soil sample locations are shown in Figure 2. Test results indicated that BETX and fuel hydrocarbons were not detected in the soil samples. Lead was detected at concentrations greater than MTCA cleanup levels in samples G-3 and G-4, obtained from the base of 4 engineers the excavation (770 mg/kg and 460 mg/kg, respectively). Lead was not detected at concentrations greater than the MTCA guideline of 250 mg/kg in L the remaining samples. t Additional soil was removed from the excavation on January 30 and 31, 1991, based on the concentrations of lead detected in G-3 and G-4. Three discrete soil samples (G-6 through G4) and four composite samples (GSP-5 through GSP-8) were obtained and submitted for analysis of lead after the additional soil excavation. Sample G-8 was also analyzed for BETX and fuel hydrocarbons. The concentrations of lead in samples G-6 through G-8, and GSP-5 through GSP-8 either were not detected or were less than MTCA cleanup levels (Table 2). BETX was not detected in sample G-8. PRODUCT LINE EXCAVATIONS Five discrete soil samples (PL-1 through PL-5) were obtained from the product line excavations on December 31, 1990 and submitted for analysis of BETX and fuel hydrocarbons. Soil sample analytical results are summarized ' in Table 3. Soil sample locations are shown in Figure 2. Fuel hydrocarbons i ' (quantified as gasoline) were detected at concentrations greater than MTCA `-, cleanup levels in sample PL-3. Ethylbenzene and xylenes were detected at ? concentrations less than MTCA cleanup levels in sample PL-3. Benzene and ~ toluene were not detected in this sample. Sample PL-3 was obtained from the _ western portion of the service islands adjacent to Pacific Highway South, as shown in Figure 2. BETX and fuel hydrocarbons were not detected in the remaining samples. Additional soil was removed from the product line excavation in the vicinity of PL-3 on January 9, 1991. Three discrete soil samples (PL-6 through PL-8) and one composite sample (PL-SP) were obtained and submitted for analysis of BETX and fuel hydrocarbons after the additional soil was removed. Test results indicated that BETX and fuel hydrocarbons were not detected in these samples. Sample PL-6 also was analyzed for total lead. Lead was not detected in sample PL-6. VAPOR TiJELL TEST PIT EXCAVATION TPH was detected at a concentration of 420 mg/kg in the soil sample t tested from a depth of 23 feet in vapor well VP-1 at the time the well was constructed in July 1990. BETX was not detected in this sample. A test pit excavation was completed on January 9•and 10, 1991 at the location of VP-1 to determine the source and extent of the petroleum hydrocarbons detected ! 5 Geo JWngineers I' in the sample from 23 feet. The vapor well casing was removed during the excavation activities. Ground water was not present in the well casing in July 1990 or on January 9, 1991. As indicated in our report dated January 17, 1991, we expect that the depth to ground water beneath the site f is greater than 100 feet. The vapor well excavation was completed at a depth of about 19 feet. Excavation deeper than.18 feet was not possible because of severe sloughing of the test pit sidewalls. Excavation was suspended- after two active { utilities crossing the site were undermined by sloughing from the excavation sidewalls. Approximately 180 cubic yards of soil were removed from the vapor well test pit excavation. The excavation was backfilled on i January 10, 1990, with the soil that was removed from the excavation. Three discrete soil samples (VW-1, VW-2 and VW-3) were obtained from g the depths of 13, 16 and 18 feet in the excavation. Three composite samples (VWSP-1, VWSP-2 and VWSP-3) were obtained from the soil stockpile. The samples were collected on January 9 and 10, 1991. The soil samples were analyzed for fuel hydrocarbons and TPH. The results of analytical 'testing are summarized in Table 1. Fuel hydrocarbons were not detected in any of the six samples. TPH was detected at concentrations less than MTCA cleanup levels in all of the samples, except VW-2. TPH was detected at a concentration of 280 mg/kg in VW-2. Examination of the chromatograms included with the fuel hydrocarbons analysis for the six samples obtained from the vapor well excavation and soil stockpile indicates that. petroleum hydrocarbons are either not present or are present at very low concentrations in the soil removed from the vicinity of VP-1. SOIL DISPOSAL AND BACKFILLING OF EXCAVATIONS Approximately 110 cubic yards of soil were stockpiled at the site pending disposal at the Kitsap County Sanitary Landfill.- The stockpile consisted of about 50 cubic yards of petroleum -contaminated soil from the waste oil tank excavation; about 50 cubic yards of lead -contaminated soil from the gasoline tank excavation; and about lu cubic yaras or gasoiine- a. contaminated soil from the product line excavation. one composite sample (Wo-8 composite) was obtained from the stockpile of soil removed from the waste oil tank excavation. The sample was analyzed for fuel hydrocarbons, TPH and TCLP metals. The concentrations of fuel 6 s Geo N Engineers hydrocarbons, TPH and TCLP metals either were nondetected or were less than MTCA cleanup guidelines in this sample (Table 1). The soil stockpile was not used as backfill, however, because the stockpile includes soil removed from the base of the excavation after TPH was detected at a concentration of 210 mg/kg in sample WO-1. A separate soil sample (sample 7a) obtained from the waste oil tank excavation during our 1989 study was tested for PCBs, purgeable halocarbons and flash point. PCBs and purgeable halocarbons were not detected in this sample. The flash point was greater than 200 degrees Fahrenheit. One composite soil sample (GSP-8) was obtained from the stockpile of soil removed from the gasoline tank excavation after lead was detected at concentrations greater than MICA cleanup levels in samples G-3 and G-4. Lead was detected at a concentration of 44.2 mg/kg in sample GSP-8. This soil stockpile will be transported to the landfill based on the lead concentrations detected in G-3 and G-4. Approximately 10 cubic yards of soil were excavated from the service island excavation after fuel hydrocarbons (quantified as gasoline) were detected at a concentration of 110 mg/kg in sample PL-3. This soil also will be transported to the landfill. We received permission for disposal of ,the soil at Kitsap County Landfill on March 5, 1991. The soil was transported to the landfill by CW Trucking & Excavating of Poulsbo, Washington, on March 19, 1991. Composite samples obtained from the remaining gasoline tank and product line soil stockpiles (SP-1, SP-2, G-SP-A, G-SP-B, GSP-5, GSP-6, GSP-7 and PL-SP) were analyzed for one or more of the following: fuel hydrocarbons, BETX and lead. The concentrations of fuel hydrocarbons, BETX and lead either were nondetected or were less than MTCA cleanup guidelines in these samples (Tables 2 and 3). The soil stockpiles that these samples were collected from were used to backfill the excavations at the site based on the chemical analytical data. The waste oil tank and product line excavations were backfilled by Sleister on March 25, 1991. The gasoline storage tank excavation was not backfilled, as requested by Unocal on March 22, 1991. CONCLUSIONS The results of our observations and chemical testing indicate that petroleum -related contamination of regulatory significance is not present 7 Geo ,C�Engineers in the vicinity of the underground storage tank and product line excavations at the site of Unocal Service Station 6227. Soil samples collected from the final limits of the excavations and from the stockpiles used to backfill the excavations did not contain petroleum -related contaminants at concentrations r exceeding MTCA Method A cleanup levels. LAs indicated in previous reports, the service station facilities are constructed on imported fill placed at the -head of a ravine. It is possible C� that the concentrations of TPH detected in soil samples from the vapor well excavation and'the sample obtained from a depth of 23 feet in the vapor well boring are the result of interferences caused by organic matter present in the imported fill. In our opinion, petroleum -related contamination of : regulatory significance is not present in the location of the former vapor well at this site. LIMITATIONS We have prepared this report for use by Unocal. This report may be made available to regulatory agencies. This report is not intended for use by others and the information contained herein is not applicable to other sites. Our interpretation of soil conditions during remediation is based on field observations and chemical analytical data. It is possible that areas with contamination may exist in portions of the site that were not excavated or analyzed. In addition, regulatory requirements may change and could be applied retroactively. - 0 0 a - 8 r• GeoEngineers �l NO,., Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time this report was prepared.

The boring was drilled on July 25, 1990 to a depth of 33 feet using drilling equipment owned and operated by McDonald Holt, Inc. The drilling equipment was cleaned with a hot-water pressure washer prior to drilling the boring. The soil sampling equipment was cleaned with a trisodiumphosphate (TSP) solution and rinsed with idistilled water prior to drilling. A geologist from our staff determined the boring location, examined and classified the soils encountered, and prepared a detailed log of the boring. Soils encountered were classified visually in general accordance with ASTM D-2488-83, which is described in Figure A-1. An explanation of the boring log symbols is presented in Figure A-2. The boring log is given in Figure A-3. Soil samples were obtained from the boring using a Dames & Moore split - barrel sampler (2.4-inch ID). The sampler was driven 18 inches by a 300-pound weight falling a vertical distance of approximately 30 inches. The number of blows needed to advance the sampler the final 12 inches or other specified intervals is indicated to the left of the corresponding sample notations on the boring logs. One soil sample was selected from the boring for chemical analysis of benzene, ethylbenzene, toluene, and xylenes (BETX), and total petroleum hydrocarbons (TPH). The sample that was tested is denoted in the boring log with a "CA." Chain -of -custody procedures were followed in transporting the soil sample to the laboratory. FIELD SCREENING OF SOIL SAMPLES A GeoEngineers representative conducted field screening on soil samples obtained from the boring. Field screening results are used as a general guideline to delineate areas of potential petroleum -related contamination. In addition, screening results are used to aid in the selection of soil samples for chemical analysis. The screening methods employed included: A - 1 Geoff®®Engineers (1) visual examination, (2) sheen testing, and (3) headspace vapor testing using a Bacharach TLV Sniffer calibrated to hexane. The results of headspace and sheen screening are included on the boring log. Visual screening consists of inspecting the soil for the presence of stains indicative of petroleum -related contamination. Visual screening is generally more effective when contamination is related to heavier petroleum hydrocarbons such as motor oil, or when -hydrocarbon concentrations are high. Sheen screening and headspace vapor screening are more sensitive methods which have been effective in detecting contamination at concentrations less than regulatory cleanup guidelines. Sheen testing involves placing soil in water and observing the water surface for signs of sheen. Sheens observed are classified as follows: No Sheen (NS) No visible sheen on the water surface. Slight Sheen (SS) Light colorless sheen, spread is irregular, not rapid; film dissipates rapidly. Moderate Sheen (MS) Light to heavy film, may have some color or iridescence; spread is irregular to flowing, maybe rapid; few remaining areas of no sheen on water Isurface. Heavy Sheen (HS) Heavy colorful film with iridescence; spread is rapid,_ and sheen flows off the sample; entire water surface may be covered with sheen. Headspace vapor screening involves placing a soil sample in a plastic sample bag. Air is captured in the bag and the bag is shaken to expose the soil to the air trapped in the bag.. The probe of a Bacharach TLV Sniffer is inserted in the bag and the TLV Sniffer records the concentrations of combustible vapor in the' air removed from the sample headspace. The TLV Sniffer records concentrations in parts per million (ppm) and is calibrated i to hexane. The TLV Sniffer is designed to. quantify combustible gas concentrations in the range between 100 and 10',000 ppm. Field screening results are site and boring specific. The results vary with temperature, soil type, soil moisture content and type of contaminant. A - 2 Geo,OEngineers VAPOR PROBE CONSTRUCTION Two -inch -diameter, Schedule 40 PVC pipe was installed in Boring VP-1 at the completion of drilling. The lower portion of the PVC pipe is machine slotted (0.02-inch slot width) to allow entry of hydrocarbon vapors and water (if present) into the well casing. Medium sand was placed -in the borehole annulus surrounding the slotted portion of the PVC pipe. Vapor probe construction is indicated in Figure A-3.. CHEMICAL ANALYTICAL PROGRAM One soil sample was analyzed by Analytical Technologies, Inc. The soil sample was analyzed for total petroleum hydrocarbons. using freon extrac- tion/infrared spectroscopy detection in accordance with EPA Method 418.1. Gas chromatography detection was used to quantify benzene, ethylbenzene, toluene and xylenes in accordance with EPA Method 8020.

(Phase 11) activities conducted at the above - referenced gasoline station and convenience store in Federal Way, Washin.gtoul provided in this report is the following inform ation: a brie' description of the site setdug and background; merhods used to conduct the Phase B sampling; laboratory analytical methods and results; and s»ary and conclusions. l cluded as attachments to this letter report is a vicinity map, a site diagram depicting sampling locations, soil boring logs, and laboratory data sheets with chain -of -custody documentation. Mr. Eric Chapman. of ARCS conducted the fieldwork in support of this project and prepared this report. The scope of work for this project included collecting subsurface soil samples arotmd the ' underground storage tank WSTj and fuel island areas. The scope of work is described in onr proposal and contact dated March 23, 9001. This work was done in accordance with the contract and ARCS' General Terms and Conditions_ Written authorization to proceed with this project was received from Mr. George Stearn on April 29, 2001.

The local topography slopes from the southlsoutheast to the northwest towards Poverty Bay. Wc)rmation obtained from nearby water wells indicates that the depth to ground water ranges from 55 t4 over ISO feet below ground surface, with a reported flow direction to the northhiorthwesL The subject property has reportedly been occupied by a gasoline service station since the early 1970s. In 1999, Three undergroupd storage tanks (USTs) were removed from the subject property. A release of petroleum products to soil was reported to F-cology as the time of the Temovals_ According to the property owner, the soil contamination was limited to the tank area and was cleanup up at the time of the removals. Three new USTs were installed in 1995. At the time of the installations, all of the fuel dispensers and piping were upgraded, An automatic leak detection system that monitors the tanks and piping is located in the site office. The property owner has reported no known releases or losses of product from the USTs, piping or dispensers- SiMEMLAR-'Y OF FIELD ACTMTIES ARCS' was retained to conduct subsurface sampling activities at this site in support of the potential sale of the business and property. The purpose of the sampling is to determine if anY obvious indications of gasoline contamivation exist in subsurface soils and/or ground water. This section describes the methods used to collect samples from the site. . SAMPLINGMETHODSAIND SOIL CHARACTE IZ477ON Sampling activities were conducted on April 3, 2001. ARCS subcontracted with Environmental Smvices hTetworl Northwest (ESN) to advance temporary soil borings at the site using a ' Strataprobe rig. The Strataprobe rig uses direct -push Techniques to advance a steel sampling probe into subsurface soils. Following the completion of each soil boring, the sampler and all steel rods used for the boring were decontaminated using a solution of Aleono)Jm and water, followed by a thorough rinse with clean water. After sampling, the temporary borings were filled with bentowe chips and then sealed with cold patch asphalt.

The locate identified buried electrical, gas and water lines lea.dW9 to the property from Redondo Road, Dash Point }load, and Pacific Highway South►_ in addition to -lie identified utilities, the property owner stated that other `'unmarked" underground limes were located new the planned sampling locations. The presence of unknown underground utilities and piping limited the number of sampling ;locations from the original scope of five borings to four borings. Four soil borings were advanced at the site (FWS-B 1 through FIWS-B4), as indicated on the Site Diagram. Soil borings FWS-BI and B? wereadvanBoringced an the north side of the UST area, to a FWS B3 was advancedon the west side of depth of IS feet below ground surface (bgs)- the dispenser island, to a depth of 9 feet bsg. Borings FWS-B4 was advanced on the north portion of the lot, adjacent to the bioswale, to a depth 18 fee# bsg. Please note that boring FWS-B4 is located at an elevation of approximately 15 to 20 feet below the Elevation of the gas station; electively making this boring 130 to 35 feet below the grade of Ti ► smtion parking area. A split -spoon sampler was used to recover continuous soil samples at 3-foot intervals. Soils encountered in the borings consisted of well graded, tine to medium -grained silty sand with gravels and cobbles. Soils recovered from the borings were moist, but ground water,was not encountered in auY of the borings. No staininb or fuel -type odors were observed in the soils recovered from the borings. Soil boring logs that include soil characterization information are presented in Attachment A. • FMI.D SCREENOW AND SAMPLE COL'L'ECHON Soil samples were collected from selected depths in each boring- A portion of each sample interval was placed into a plastic bag for headspwe screening and characterization using a photo- ioni 2:riou detector CPIs]) calibrated to an isobutylene standard. A separate portion of each sample interval was reserved for laboratory analysis. Done of the soils recovered from the borings exhibited staining or odors indicative of petroleum contamination - Soil samples reserved for analysis were placed into 4-ounce glass containers supplied by the laboratory. Each sample was labeled and then planed in an ice -filled cooler pending transport to the laboratory. Laboratory analytical methods and results are discussed in the following section of this report. LABO"TORY ANALYTICAL MITHODS AND RESULTS Soil samples collected from the temporary borings were transported under standard chain -of - custody protocol to ESN's laboratory in Lacey, Washington, Samples from each boring were analyzed for gasoline -range total petroleum hydrocarbons ('TPH-G) by Washington State Method WTP14-G and for benzene, toluene, ethyl benzene and xylenes (BT - by EPA Method 9021 B- The laboratorrresults, summarized in Table 1, indicate that none of the samples submitted for SEP-28-05 16:13 Sep-28-05 04:06pm From - P-05 R-054 Job-886 T-485 P.05/16 F-740 u April 9, 2001 Phase If Report — Shell Service Station and Mini-Rdarr, FederQl'tiYay.

Dear Mr. CarlSOn. Thank you for- providing the final clean-up report for the above referenced property. Based on the informatiob provided, proper procedures were followed regarding the'tank removal, and site remediation pursuant to federal and state regulations (40 CFR Part 280,, and WAC 173-340, . reapeetively). Also based on the information provided, recommended clean --up standards were wet- or battered after the remediation process, With the exception of soil contamination at 23 foot depth which could not be sampled or remadiatede, the report did indicate, however, that the contamination was insuffici ant to warrant further action, and the Department of Ecology will abide by that professional opinion, in lieu of additiorial information, The clean-up standards are referenced in the proposed amendments 173-340-7¢0.

The site is located northwest of the intersection between Pacific Highway South and Dash Point Road, as shown on the Vicinity Map, Figure 1. The general layout of the site is shown on the Site Plan, Figure 2. Two 10,000-gallon steel gasoline storage tanks, one 550-gallon steel waste oil tank and one 550-gallon steel heating oil tank were removed from the site between September 12 and 14, 1989. The steel gasoline storage tanks were replaced by two 12,000-gallon double -wall fiberglass -coated steel underground storage tanks. The steel waste oil tank was replaced with a 520-gallon double -wall fiberglass -coated steel tank. The steel heating oil tank was removed but not replaced. The purpose of our services was to observe and evaluate subsurface soil conditions in the excavations, and to develop a remediation plan, if necessary. GeoEngineers' scope of services completed for this project is listed below. 1. Observe and document the excavation of the four underground storage tanks at the site. 2. Obtain soil samples from the limits of the storage tank excava- tions for chemical analysis of petroleum -related contaminants. Field screening was conducted on each soil sample for evidence of contamination using visual, water sheen and volatile organics headspace screening methods. These methods are described in Appendix A. 3. Obtain one soil sample for chemical analysis from beneath a segment of the product lines that was exposed during repair of a broken water line. Geo 1W ngineers 4. Obtain composite samples for chemical analyses from soil removed from the excavations as required for disposal at a landfill. 5. Evaluate the field and laboratory data with regard to existing regulatory concerns. SOIL EXCAVATION AND SAMPLING GASOLINE STORAGE TANK EXCAVATION Joe Hall Construction Inc. (Joe Hall) removed the two gasoline storage tanks on September 12, 1989 from the locations shown in Figure 2. GeoEngineers was present to observe the tank removal activities and to obtain soil samples. Very minor evidence of rust and corrosion was observed on the two storage tanks. Ground water was not encountered in the excavation. The excavation extended to a depth of 18 feet in the southern portion and 19 feet in the northern portion. Backfill surrounding the tanks consisted of sandy gravel. Fine to medium gravelly sand interbedded with thin layers of gravel and cobbles was encountered in the walls of the gasoline tank excavation to a depth of 18 feet. The gravelly sand unit is underlain by silty sand with occasional gravel. Physical evidence of petroleum -related contamination was detected in the backfill material in the vicinity of the fill port for the super unleaded gasoline storage tank. Approximately 600 cubic yards of contam- inated backfill was transported to Fife Sand and Gravel for aeration. Non - contaminated backfill was transported to Fife Sand and Gravel for use as fill material at other locations. The excavation was lengthened on September 12 to accommodate the larger gasoline storage tanks. The final limits of the excavation are shown in Figure 2. Seven soil samples (Samples 3 through 9) were obtained from the limits of the completed excavation. Sample 1 was obtained from the non - contaminated backfill removed from the tank excavation and Sample 2 was collected from the contaminated backfill that was transported to Fife Sand and Gravel. All of these soil samples were analyzed for the presence of total petroleum hydrocarbons (TPH by EPA Method 418.1) and for benzene, ethylbenzene, toluene and xylenes (BETX by EPA Method 8020). The sample 2 Geo b Engineers locations are shown in Figure 2. Table 1. Laboratory reports for Appendix B. Analytical results are summarized in the soil samples are included in A section of the product lines was exposed during tank replacement operations to facilitate the repair of a broken water line. The location of the water line excavation is shown on Figure 2. Two discrete soil samples were obtained from beneath the exposed product lines and composited. This composite sample (Sample 10) was submitted for laboratory analysis of BETX and TPH. The current Washington State Department of Ecology (Ecology) cleanup guidelines for petroleum -contaminated soil are 200 ppm TPH, 660 ppb (.66 ppm) benzene, 14 ppm ethylbenzene and 143 ppm toluene. Test results indicated that concentrations of benzene, ethylbenzene, toluene and TPH were either nondetected or were less than current Ecology cleanup guidelines (Table 1) in the soil samples obtained from the limits of the gasoline storage tank excavation, from beneath the exposed product line and from the non -contaminated soil that was transported to Fife Sand and Gravel for use as fill. A TPH concentration greater than Ecology cleanup guidelines was detected in Sample 2, obtained from the contaminated backfill material. WASTE OIL/HEATING OIL TANKS EXCAVATION The waste oil and heating oil tanks were removed by Joe Hall on September 14, 1989. Minor evidence of corrosion was noted on both tanks. The two small -diameter copper pipes that serve as heating oil supply and return pipes were encountered 2.3 feet below the asphalt surface layer in the north wall of the excavation. Petroleum -like odor and staining were noted in the soil surrounding these two pipes. Six soil samples (Samples la through 6a) were obtained from the initial limits of the waste oil/heating oil tanks excavation. Sample 7a was a composite sample obtained from the backfill material removed from the excavation and transported to Fife Sand and Gravel for temporary storage. Approximately 100 cubic yards of backfill from the waste oil/heating oil tanks excavation was transport to Fife Sand and Gravel. Soil sample locations are indicated on Figure 2. 3 Geoff Engineers Field screening of soil samples obtained from the limits of the excavation indicated the possible presence of heavier hydrocarbon contamina- tion in the four walls and floor of the excavation. Because the service station building is located immediately north and a service island concrete slab immediately south of the excavation, it was determined that additional soil could not be removed from the walls of the excavation without endangering these structures. It was possible to remove an additional 2.5 feet of soil from beneath the waste oil tank in an attempt to determine the vertical extent of contamination in this area. The results of field screening and laboratory analysis are listed in Table 2. Samples la, 4a, 7a and 8a resulted in TPH concentrations greater than Ecology cleanup guidelines (Table 2). Sample la was obtained from beneath the heating oil tank at depth of 6 feet. Sample 4a was obtained from 0.5 feet below the copper pipes that were encountered in the north wall of the excavation. Sample 7a was a composite sample obtained from the soil removed from the excavation and transported to Fife Sand and Gravel. Soil Sample 8a was obtained from the deepened excavation at a depth of 8.5 feet. SOIL DISPOSAL We were informed by Joe Hall Construction that the 700 cubic yards of soil temporarily stored at Fife Sand and Gravel was transported on November 21, 1989 to Coal Creek Landfill for disposal. Del Lovell of Joe Hall Construction indicated that permission for disposal was given by Seattle -King County Department of Public Health based on the results of chemical analyses on samples of the soil removed from Service Station 6227. CONCLUSIONS AND RECOMMENDATIONS Based on the results of our observations and testing, gasoline -related contamination of regulatory significance is not present in the vicinity of the underground gasoline storage tanks. However, the results of this study indicate the presence of subsurface petroleum -related soil contamination in the vicinity of the new waste oil tank.' Excavation of this soil would ' require removal of the service station building and the new tank. The residual contamination in the vicinity of the waste oil tank appears to be limited in extent. It is our opinion, therefore, that this 4 �Qa Geo �F—Engineers contamination does not represent a hazard to human health or the environment and that removal of the building is not warranted. LIMITATIONS We have prepared this report for use by Unocal. This report may be made available to regulatory agencies. This report is not intended for use by others and the information contained herein is not applicable to other sites. Our interpretation of soil conditions during remediation is based on field observations and chemical analytical data. It is possible that areas with undetected contamination may exist in portions of the site which were not excavated or analyzed. Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time the report was prepared. No other conditions, express or implied, should be understood. JF:JAM: db Respectfully submitted, GeoEngineers, Inc. lia �o e ydrogeologist James A. Miller, P.E.

Field screening results are used as a general guideline to delineate areas of potential petroleum -related contamination in soils. In addition, screening results are used to aid in the selection of soil samples for chemical analysis. The field screening methods employed included: (1) visual examination, (2) sheen testing, and (3) headspace vapor testing using a Bacharach TLV Sniffer calibrated to hexane. The results of headspace and sheen screening are included on Tables 1 and 2 in the text of this report. Visual screening consists of inspecting the soil for the presence of stains indicative of petroleum -related contamination. Visual screening is generally more effective in detecting the presence of heavier petroleum hydrocarbons such as motor oil or when hydrocarbon concentrations are high. Sheen screening and headspace vapor screening are more sensitive methods whidh have been effective in detecting contamination at levels less than regulatory cleanup guidelines. Sheen testing involves placing soil in water and observing the water surface for signs of sheen. Sheens are classified as follows: NS - No Sheen No visible sheen. SS - Slight Sheen Light colorless sheen, spotty to globular; spread is irregular, not rapid; areas of no sheen remain; film dissipates rapidly. MS - Moderate Sheen Light to heavy film, may have some color or iridescence, globular to stringy; spread is rapid; irregular to flowing. HS - Heavy Sheen Heavy colorful film with iridescence; stringy, spread is rapid; sheen flows off the sample; most of water surface is covered. A - 1 Geo REngineers Headspace vapor screening involves placing a soil sample in a plastic sample bag. Air is captured in the bag and the bag is shaken to expose the soil to the air trapped in the bag. The probe of a Bacharach TLV Sniffer is used to puncture the bag, the instrument withdraws the air in the bag and the TLV Sniffer records the concentration of combustible vapor in the air removed from the sample headspace. The TLV Sniffer records concentrations in parts per million (ppm) and is calibrated to hexane. The Sniffer is designed to quantify combustible gas concentrations in the range between 100 and 10,000 ppm. Field screening results are site specific. The results vary with temperature, soil type, type of contaminant, and soil moisture content. CHEMICAL ANALYTICAL PROGRAM Soil samples obtained between September 12 and 14, 1989 were analyzed by Enviros Corporation or Sound Analytical Services, Inc.. The soil samples were analyzed for TPH and/or BETX. Infrared spectrophotometry methods were used to analyze for petroleum hydrocarbons (EPA Method 418.1) and gas chromatography was used to quantify BETX (EPA Method 8020). The composite sample obtained from backfill material surrounding the gasoline tanks was also analyzed for fuel hydrocarbons by modified EPA Method 8015. The composite sample obtained from backfill material surrounding the heating oil and waste oil tanks was analyzed for PCBs, chlorinated hydrocarbons (EPA Method 8010), and TPH (EPA Method 418.1).

Box 76 Seattle, Washington 98111 Attention: Mr. Gary Gunderson Results of Supplemental Field Testing Unocal Service Station 6227 King County, Washington File No. 0161-041-BO4 I INTRODUCTION The results of our supplemental testing for subsurface petroleum - related contamination at the site of Service Station 6227 are presented in this report. The site is located northwest of the intersection between 4 Pacific Highway South and Dash Point Road in the Federal Way area of King i-r County, Washington. The site location and surrounding features are shown lj in Figure 1. The general layout of the'site is shown on the Site Plan, Figure 2. GeoEngineers previously completed two studies at Service Station 6227. We provided geotechnical services regarding fill embankment and storm drain ' replacement in 1987. The results of our geotechnical consultation are L presented in our report dated June 4, 1987. We observed the removal of the former underground gasoline, waste oil and heating oil storage tanks at the 4 site in September 1989. The results of our observations during tank removal activities at the site are presented in our report dated November 27, 1989. ? Total petroleum hydrocarbons � p y (TPH) were detected at concentrations greater than the Washington Department of Ecology (Ecology) cleanup guidelines in the walls and base of the excavation completed for removal of the waste oil and heating oil tanks in 1989. The excavation was between the r� service station building and the southern service island (Figure 2). }. Removal of all the contaminated soil from this area was not attempted because of the potential for endangering the building and service island concrete slab. The former gasoline and waste oil tanks were replaced with new tanks. The heating oil tank was removed, but not replaced. 1 r , GeoEngineers, Inc. 2405 Moth Ave. NE, Suite l05 • Bellevue, WA 98005 j Telephone (206) 746-5200 ' "` Fax. (206) 746-5068 t Geoff Engineers t^+ Unocal January 17, 1991 Page 2 i �— Based on the results of our observations during 1989 tank removal activities, we concluded that the residual contamination in the vicinity of the waste oil tank was limited in extent. We also concluded that this contamination did not represent a hazard to human health or the environment. SCOPE The purpose of our supplemental services is to determine if shallow i+ ground water exists beneath the site and if that ground water has been affected by residual waste oil -related soil contamination. The scope of services completed for this study includes: 1. Drill one exploration boring (VP-1) in the vicinity of the former waste oil and heating oil tank excavation using hollow -stem auger L) drilling equipment. 2. Obtain soil samples at 5-foot intervals from the boring and n conduct field screening on the soil samples for evidence of 1 contamination using visual, water sheen and headspace vapor -, screening methods. The field screening methods are described in Appendix A. 3. Test one soil sample from the boring for the presence of benzene, S ethylbenzene, toluene and xylenes (BETX) by EPA Method 8020 and I� for total petroleum hydrocarbons (TPH) by EPA Method 418.1. f4. Install a 2-inch-diameter PVC well casing with a flush -grade, locking surface monument in the boring. 5. Evaluate the field and laboratory data with regard to current regulatory criteria. SITE CONDITIONS GENERAL Service Station 6227 is located within the Federal Way city limits in an area of primarily residential development. The site is located at the head of a ravine that slopes steeply downward toward the north-northwest. The surface of the site is paved with asphaltic concrete and slopes gently downward toward the northwest. The elevation of the site is approximately 420 feet above sea level. The service station is inactive. The property includes a service station building, three covered service islands, two 12,000-gallon e ft I Geo�Engineers 1 Unocal January 17, 1991 Page 3 underground gasoline storage tanks and one 520-gallon underground waste oil tank. These tanks were installed at the site in 1989. The locations of the current facilities at the service station are shown in Figure 2. SUBSURFACE SOIL CONDITIONS Subsurface soil conditions in the vicinity of the former waste oil and heating oil tanks were explored by drilling one exploration boring (VP-1) at the location indicated in Figure 2. Details of the field exploration program and the boring log are presented in Appendix A. Based on the results of our earlier geotechnical study, we understand !_ that the service station is constructed on imported fill placed at the head of the ravine. Fill consisting of sand and gravel with variable amounts of silt was encountered from the base of the asphalt paving to a depth of 25 feet in VP-1. Very dense silty sand with gravel grading to gravel with sand and silt (glacial till) was encountered beneath the fill to the total depth of the boring ) (33 feet). !' GROUND WATER CONDITIONS Ground water conditions were explored by installing a vapor probe well casing in Boring VP-1. Construction details for the vapor probe are included in Appendix A. Ground water was not encountered in the boring. Based on the geology 1 of the area, we anticipate that the depth to ground water at this site is greater than 100 feet. It is possible that runoff water from higher ground east and south of the site drains down the filled ravine during rainy months of the year. "Perched" ground water may exist seasonally above the glacial 1 till unit. '- SUBSURFACE CONTAMINATION Potential subsurface petroleum -related contamination at the location of 1 VP-1 was evaluated by: (1) conducting field screening on soil samples from the boring for evidence of contamination using visual, water sheen and headspace vapor screening methods, and (2) testing one soil sample from the boring for BETX and TPH. The subsurface soil analytical data are summarized in Table 1. The field screening results are presented on the boring log. The laboratory ti report is included in Appendix B. Geo,� Engineers Unocal January 17, 1991 Page 4 A slight sheen was observed on the soil samples obtained from the depths of 17 and 23 feet in VP-1. Headspace vapor concentrations were less than 100 parts per million (ppm) for all of the soil samples from VP-1. The soil sample from a depth of 23 feet was tested for BETX and TPH. BETX was not detected. TPH was detected at a concentration of 420 milligrams per kilogram (mg/kg) in this sample. Mr. Joe Hickey of Ecology was informed on August 31, 1990 of the presence of the subsurface soil contamination detected in VP-1. Mr. Hickey also has a copy of our report dated November 27, 1989, regarding our observations during tank removal at the site. CONCLUSIONS AND RECOMlENDATIONS The results of this study indicate the possible presence of petroleum - related contamination at depth beneath the site of Service Station 6227. The concentration of TPH detected in the soil sample obtained from 23 feet in VP-1 (420 mg/kg) exceeds the current Ecology soil cleanup guideline for TPH of 200 mg/kg. Three soil samples obtained from the limits of the heating oil and waste oil tank excavation in 1989 also exceeded Ecology's cleanup guideline for TPH. We drilled VP-1 in an attempt to determine whether shallow or 'perched' ground water is present beneath the service station site. Because of the variable geologic conditions beneath the site, the results of this effort are inconclusive. We understand that Unocal intends to remove the existing gasoline and i waste oil tanks from the site in the near future. We recommend that additional soil be excavated from the location of the former waste oil and ! heating oil tank excavation. Soil should be removed from this area until i the concentrations of petroleum -related contamination are less than Ecology cleanup guidelines. It may be necessary to demolish the service station building and a portion of the southern service island to excavate all of the contaminated soil. We further recommend that an exploratory excavation be completed in the vicinity of VP-1 to determine the extent of the subsurface contamination detected in this boring. The depth of this excavation will be approximately } 25 feet. It may be necessary to extend this excavation in the direction of the service station building if subsurface conditions suggest that the I Geoff syti Engineers Unocal January 17, 1991 Page 5 source of contamination in VP-1 is the waste oil tank or a source beneath the building. Soil samples obtained from the exploratory excavation should be submitted for laboratory analysis of petroleum hydrocarbons by EPA Methods 8015 (modified) and 418.1. We understand that the storm drain that was replaced in 1987 was installed around the western perimeter of the site. If the storm drain is encountered during excavation it may be necessary to temporarily remove a portion of the drain pipe to allow excavation to continue. The storm drain should be fully restored upon completion of work at the site. We recommend that contaminated soil be treated on the site if feasible. In our opinion, land farming/biological treatment is the most practical method of soil remediation at this site. Treatment should consist of spreading the soil on a lined and bermed area of the property, tilling the soil regularly, and adding nutrients (fertilizer) and water as necessary to promote biodegradation of the petroleum product. LIMITATIONS We have prepared this report for use by Unocal. This report can be made available to prospective buyers of the property and to regulatory agencies. The report is not intended for use by others and the information contained herein is not applicable to other sites. Our interpretations of subsurface conditions are based on data from one boring and from previous excavations at the site. It is possible that areas with undetected contamination exist in areas of the site that were not explored or analyzed. - 0 0 o - Geoff !'.,� Engineers Unocal January 17, 1991 Page 6 Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time the report was prepared.

O Y �i- 0 0 r �� J Geol Engineers A P P E N D I X A FIELD EXPLORATIONS DRILLING AND SOIL SAMPLING PROGRAM Subsurface conditions at Service Station 6227 were explored by drilling one boring (VP-1) using truck -mounted, hollow -stem auger drilling equipment at the location indicated in Figure 2. The boring was drilled on July 25, 1990 to a depth of 33 feet using drilling equipment owned and operated by McDonald Holt, Inc. The drilling equipment was cleaned with a hot-water pressure washer prior to drilling the boring. The soil sampling equipment was cleaned with a trisodiumphosphate (TSP) solution and rinsed with distilled water prior to drilling. A geologist from our staff determined the boring location, examined and classified the soils encountered, and prepared a detailed log of the boring. Soils encountered were classified visually in general accordance with ASTM D-2488-83, which is described in Figure A-1. An explanation of the boring log symbols is presented in Figure A-2. The boring log is given in Figure A-3. Soil samples were obtained from the boring using a Dames & Moore split - barrel sampler (2.4-inch ID). The sampler was driven 18 inches by a 300-pound weight falling a vertical distance of approximately 30 inches. The number of blows needed to advance the sampler the final 12 inches or other specified intervals is indicated to the left of the corresponding sample notations on the boring logs. One soil sample -was selected from the boring for chemical analysis of benzene, ethylbenzene, toluene, and xylenes (BETX), and total petroleum hydrocarbons (TPH). The sample that was tested is denoted in the boring log with a "CA." Chain -of -custody procedures were followed in transporting the soil sample to the laboratory. FIELD SCREENING OF SOIL SAMPLES A GeoEngineers representative conducted field screening on soil samples obtained from the boring. Field screening results are used as a general guideline to delineate areas of potential petroleum -related contamination. In addition, screening results are used to aid in the selection of soil i samples for chemical analysis. The screening methods employed included: ! A - 1 Geoff Engineers (1) visual examination, (2) sheen testing, and (3) headspace vapor testing using a Bacharach TLV Sniffer calibrated to hexane. The results of headspace and sheen screening are included on the boring log. Visual screening consists of inspecting the soil for the presence of stains indicative of petroleum -related contamination. Visual screening is generally more effective when contamination is related to heavier petroleum hydrocarbons such as motor oil, or when hydrocarbon concentrations are high. Sheen screening and headspace vapor screening are more sensitive methods which have been effective in detecting contamination at concentrations less than regulatory cleanup guidelines. Sheen testing involves placing soil in water and observing the water surface for signs of sheen. Sheens observed are classified as follows: No Sheen (NS) No visible sheen on the water surface. Slight Sheen (SS) Light colorless sheen, spread is irregular, not rapid; film dissipates rapidly. Moderate Sheen (MS) Light to heavy film, may have some color or iridescence; spread is irregular to flowing, maybe rapid; few remaining areas of no sheen on water surface. Heavy Sheen (HS) Heavy colorful film with iridescence; spread is rapid, and sheen flows off the sample; entire water surface may be covered with sheen. Headspace vapor screening involves placing a soil sample in a plastic sample bag. Air is captured in the bag and the bag is shaken to expose the soil to the air trapped in the bag. The -probe of a Bacharach TLV Sniffer is inserted in the bag and the TLV Sniffer records the concentrations of combustible vapor in the air removed from the sample headspace. The TLV Sniffer records concentrations in parts per million (ppm) and is calibrated to hexane. The TLV Sniffer is designed to quantify combustible gas concentrations in the range between 100 and 10,000 ppm. Field screening results are site and boring specific. The results vary with temperature, soil type, soil moisture content and type of contaminant. A - 2 Geo Engineers VAPOR PROBE CONSTRUCTION Two -inch -diameter, Schedule 40 PVC pipe was installed in Boring VP-1 at the completion of drilling. The lower portion of the PVC pipe is machine slotted (0.02-inch slot width) to allow entry of hydrocarbon vapors and water (if present) into the well casing. Medium sand was placed in the borehole annulus surrounding the slotted portion of the PVC pipe. Vapor probe construction is indicated in Figure A-3. CHEMICAL ANALYTICAL PROGRAM One soil sample was analyzed by Analytical Technologies, Inc. The soil sample was analyzed for total petroleum hydrocarbons using freon extrac- tion/infrared spectroscopy detection in accordance with EPA Method 418.1.

UNOCAL INTRODUCTION AND SCOPE This report summarizes the results of GeoEngineers' observations during the removal of the underground storage tanks at the site of Unocal Service Station 6227 near Federal Way in King County, Washington. The site is located northwest of the intersection between Pacific Highway South and Dash Point Road, as shown in Figure 1. The general layout of the site is shown in Figure 2. The storage tanks were removed from the site during December 1990 and January 1991. The tanks removed during this study were installed at the site in September 1989. j GeoEngineers previously completed three studies at the site. We provided geotechnical services regarding fill embankment and storm drain replacement in 1987. The results of our geotechnical consultation are �.. presented in our report dated June 4, 1987. We observed the removal of the former underground gasoline, waste oil and heating oil tanks in September 1989. The results of our observations during removal of the former tanks are presented in our report dated November 27, 1989. We drilled one exploration boring and installed a vapor well casing (VP-1) in the boring during July 1990. The results of our vapor well exploration are presented in our report dated January 17, 1991. Information provided by Unocal indicates that the service station facilities were constructed in 1969. A survey completed in February 1969 i indicates that the site was covered primarily with vegetation prior to construction of the service station facilities. Two frame buildings were located in the southwest corner of the site in February 1969. We understand that the underground storage tanks removed from the site during 1989 were the tanks installed originally in 1969. l� Two 12,000-gallon double -wall, fiberglass -coated steel gasoline storage• tanks; associated product lines; one 520-gallon double -wall, fiberglass - coated steel waste oil tank; and the vapor well were removed from the site I, between December 13, 1990 and January 10, 1991. The underground storage tanks, product lines and vapor well were not replaced. .-. p��• �. r ru w t Geo Qngineers I_ The purpose of our services was to observe and evaluate subsurface soil conditions in the excavations and to evaluate the need for remedial actions at the site. GeoEngineers' scope of services completed for this project is L listed below. 1. Observe and document the excavation and removal of the underground 1 storage tanks, product lines and vapor well at the site. 2. Obtain soil samples from the limits of the excavations and from L soil stockpiles for chemical analysis of petroleum -related contaminants. Conduct field screening on each soil sample for 1 evidence of contamination using visual, water sheen and headspace vapor screening methods. Field screening methods are described I ` in Appendix A. 3. Submit selected soil samples from the excavations and soil stockpiles for one or more of the following chemical analyses: TPH (total petroleum hydrocarbons) by EPA Method 418.1; fuel hydrocarbons by modified EPA Method 8015; BETX (benzene, ethylben- zene, toluene, xylenes) by EPA Method 8020; lead by EPA Method 7420; and TCLP (toxicity characteristic leaching procedure) metals by EPA 7000 series methodology. 4. Evaluate the field and laboratory data with regard to existing regulatory concerns. 5. Arrange for disposal of soil with petroleum -related contamination at the Kitsap County Landfill. SOIL EXCAVATION AND SAMPLING GENERAL s� Sleister (A.L. Sleister and Sons Construction, Inc.) excavated and - removed the underground storage tanks, product lines and vapor well at the site. Sleister was also responsible for the excavation of petroleum - contaminated soil encountered at the site. A representative of GeoEngineers L� was present to observe the tank removal and soil excavation activities, and to obtain soil samples from the excavations. Soil removed from the L excavations was placed in temporary on -site stockpiles. The stockpiles were Fsegregated according to the source of the soil and the relative degree -of i �._1 contamination based on field screening. Composite soil samples were collected from each individual stockpile. i 4 � 2 Vt r G e o engineers The former locations of the underground storage tanks and the vapor well, the limits of the excavations and the soil sample locations are shown C; in Figure 2. The soil sample analytical data are summarized in Tables 1, 2 and 3. Laboratory data sheets and chain -of -custody records are included I in Appendix B. I- Ecology (Washington State Department of Ecology) has established soil cleanup levels under MTCA (Model Toxics Control Act). -The MTCA Method A f soil cleanup levels for petroleum -related contamination are listed below. I' Compound MTCA Cleanup Level Benzene 0.5 mg/kg Ethylbenzene 20 mg/kg Toluene 40 mg/kg Xylenes 20 mg/kg TPH (quantified as gasoline) 100 mg/kg TPH (quantified as diesel) 200 mg/kg TPH (other) 200 mg/kg Total Lead 250 mg/kg Note: mg/kg — milligrams per kilogram. WASTE OIL TANK EXCAVATION The waste oil tank was removed on December 13, 1990. Corrosion or j pitting were not observed on the tank. Backfill surrounding the tank L_ consisted of fine to medium sand. Soil encountered in the walls and base of the excavation consisted of gravelly sand with thin layers of gravel and cobbles. Ground water was not encountered in the excavation. Seven discrete soil samples (WO-1 through WO-7) were obtained from the L; limits of the waste oil tank excavation on December 13,=1990. One sample (WO-8 composite) was obtained from the stockpiled soil on December 13, 1990. The soil samples obtained from the waste oil tank excavation limits and soil stockpile were submitted for chemical analysis of TPH and fuel hydrocarbons. 3 I„ i� (- - Geo �ngineers The sample obtained from the soil stockpile was also analyzed for TCLP L metals. Soil sample analytical results are summarized in Table 1, Soil sample locations are shown in Figure 2. The concentration of TPH (210 mg/kg) exceeded the MICA cleanup level in sample WO-1 obtained from the base of the excavation. Fuel hydrocarbons were not detected in sample WO-1. TPH and fuel hydrocarbons were either not detected or were detected at concentrations less than MTCA cleanup levels C� in the remaining samples. Additional soil was removed from the waste oil tank excavation on December 31, 1990. Sample WO-8 (a discrete sample) was { obtained from the base of the excavation after the additional soil was k. . removed and submitted for chemical analysis of TPH and fuel hydrocarbons. TPH and fuel hydrocarbons either were not detected or were detected at -� concentrations less than KTCA cleanup levels in sample WO-8. i GASOLINE TANK EXCAVATION The gasoline storage tanks were removed on December 18, 1990. Corrosion or pitting were not observed on the two gasoline tanks. Remedial -� activities at the site were suspended between December 19 and 30, 1990, because of weather conditions. Backfill surrounding the tanks consisted of fine to medium sand. Fine I to medium gravelly sand with thin layers of gravel and cobbles was encountered in the walls and base of the gasoline tank excavation. Evidence i of petroleum -related contamination was not observed in the tank backf ill or in the walls and base of the excavation. Ground water was not encountered 1= - i in the excavation. Five discrete soil samples (G-1 through G-5) were obtained from the limits of the excavation on December 31, 1990. Four composite samples t� (SP-1, SP-2, G-SP-A and G-SP-B) were obtained from the stockpiled soil. The i� soil samples were analyzed for BETX and fuel hydrocarbons. All of the samples, excluding composite samples SP-2 and G-SP-A, were also submitted for analysis of total lead. Soil sample analytical results are summarized in Table 2. Soil sample locations are shown in Figure 2. Test results indicated that BETX and fuel hydrocarbons were not detected in the soil samples. Lead was detected at concentrations greater. than MTCA cleanup levels in samples G-3 and G-4, obtained from the base of tl 4
