SEPA review - e96-0015 Gull Oil Station #240 June 12, 1996 Summary of Primary Impacts: • • • Earth Level site, composed of sand/silty gravel. No filling or grading, as site will be unchanged after remediated soil is returned. Erosion control will include use of berm constructed of natural and/or man-made elements. Soil sloped so run off will flow into open excavation area. • Air Minor dust and equipment exhaust during excavation, treatment and backfilling. Soil to be dampened to control dust, as necessary. • Water Green River is located 800' west of site. No construction to occur within 200' wetland perimeter, nor does project lie within 100 year floodplain. Any contaminated groundwater will be treated by circulation through excavations. Water will be discharged to storm/sanitary sewer after lab testing indicates levels are above acceptable state levels. Approximately 20,000 gallons to be discharged, following receipt of agency authorization. Runoff controlled by shaping soil treatment area to retain runoff onsite. • Plants Grass and small, unclassified trees growing on site since property vacated. Will be removed as part of remediation.. • Animals Site provides no known habitat for mammals or birds. No known candidate or endangered species found on site. • Energy/Natural Resources Project will only require use of energy sources during establishment of remediation system. No known energy sources needed during remediation. • Environmental Health Petroleum hydrocarbon odors may be present during excavation and treatment. Health and safety plan to be developed for project. Monitoring of air during project will be performed to minimize exposure. Some equipment noise will be present during excavation, treatment and backfilling. Noise levels to be similar to those on adjacent West Valley Hwy. Work to be conducted between 7 a.m. - 6 p.m. 2 SEPA review - e96-0015 Gull Oil Station #240 June 12, 1996 • Land/Shoreline Use • • Site is a vacant service station with attached canopy, located in TUC zone. Under Zoning Code section 18.28.050 (6), landfills and excavations are considered to be unclassified uses allowed under zoning code, if it is determined to be a significant environmental action. End result of project is a graded lot for future development, not a landfill or excavation, although both processes will be used. Existing structure to be demolished prior to remediation. Site is not classified as environmentally sensitive. • Housing No housing demolition or housing proposed for site. • Aesthetics No structures proposed. • Light and Glare No known impacts. • Recreation No known impacts. • Historic/Cultural Preservation No known places, landmarks or objects. • Transportation Site is located on West Valley Highway, near a transit stop. Project may require a street use permit during excavation if shoring is required along right-of-way. • Public Services No known impact. • Utilities Electricity, natural gas, water, telephone and sewer are probably onsite. Prior to beginning remediation, utilities permit will have to be obtained. SEPA review - e96-0015 Gull Oil Station #240 June 12, 1996 Recommendations: • • MDNS, with one mitigation measure: • The city will hire an independent consultant at the applicant's expense to determine if there is soil contamination in the right-of-way related to the subject property and what measures need to be taken to mitigate the contamination. The study will be undertaken during the demolition of the structure. The study and its conclusions shall be undertaken and presented to the City for its evaluation prior to the issuance of the land altering permit. Upon the review of this study by City staff, if it is determined that there is no contamination in the right-of-way due to the conditions at the subject property, the City will issue a land altering permit. In addition, the applicant shall be advised of the following: • A land altering permit will be issued by the Department of Public Works after the applicant submits copies of permits from Department of Ecology, EPA and Metro. • A demolition permit and appropriate utilities permits will be required prior to proceeding with any of the soil remediation work related to this application. • A permit from the Puget Sound Air Pollution Control Agency (PSAPCA) is required as a condition of the demolition.permit.

Service Station No. 240 15640 West Valley Highway Tukwila, Washington Proposed remediation at the site consists of excavation of contaminated soil for on-site treatment. Before work begins, the site will be secured by installing a chain link fence. The fence will act as a safety and control boundary to prevent site access to the public. Soil excavation will be conducted in two areas on- the site, as shown on Figure 3. An estimated 1,000 bank cubic yards will be removed from the former UST area. An estimated 500 bank cubic yards will be removed from the pump island area. Each excavation will be terminated once groundwater is encountered. We have assumed the excavations may extend to 16 feet bgs. We estimate 30 percent of the excavated soil will not contain any petroleum hydrocarbons exceeding cleanup levels (based on analytical laboratory testing to be performed). The clean soil will be backfilled in one or both of the excavations. All excavated soil containing petroleum hydrocarbons above cleanup levels will undergo on-site Solid Phase treatment. Solid Phase treatment relies on naturally occurring bacteria to biodegrade petroleum hydrocarbons in soil. The process is facilitated by adding nutrients and moisture and tilling the soil to optimize the available oxygen. The soil is spread evenly over the treatment area and is treated in approximately 1 -foot lifts. Soil samples are collected from each lift for analytical laboratory testing to document that petroleum hydrocarbon concentrations are below cleanup levels. The treated layer is then removed and placed as backfill and the next lift undergoes treatment. We estimate each lift will require 2 weeks for treatment and backfilling. Water which accumulates in the excavations will be treated by circulating the water within the excavation. After treatment, a sample of the excavation water will be collected for analytical laboratory testing to document petroleum hydrocarbons are not present above cleanup levels. The treated water will then be discharged to the storm or sanitary sewer after appropriate authorization is received. Multiple batches of excavation water may be treated until the water which reaccum- ulates in the excavation contains no petroleum hydrocarbons exceeding cleanup levels.

Post Office Box 24687 Seattle, Washington 98124 Dear Bill: ' Site Assessment Data Transmittal Gull Site No. 240 ' 15640 West Valley Highway Tukwila, Washington ' This letter transmits data obtained during a site assessment conducted by AGI Technologies (AGI) at the former Gull Service Station No. 240 in Tukwila, Washington. The site location is shown on Figure 1. ' Two soil borings were drilled to a depth of 3 feet below ground surface (bgs) using a hand auger. These borings were designated HAI and HA2, and were located below the pump islands, as shown, ' on Figure 2. Six more borings were drilled to a depth of 4-1/2 to 21-1/2 feet bgs using a truck- mounted hollow -stem auger. Four of the borings were completed as 2 -inch -diameter PVC groundwater monitoring wells. Well construction details are presented on Plate 2 in Attachment ' 1. The locations of the four monitoring wells (MW1 through MW4) and the two borings (B1 and B2) are shown on Figure 2. Soil samples were collected at 5 -foot intervals for borings extending beyond 5 feet in depth. Each soil sample was classified according to the Unified Soil Classification System as shown on Plate 1 in Attachment 1. Logs of the borings, including a well construction summary, are also presented ' on Plates 3 through 8 in Attachment 1. One soil sample from each boring was submitted to Analytical Technologies, Inc. (ATI) in Renton, Washington for qualitative analysis of gasoline-, diesel-, and oil -range petroleum hydrocarbons by Washington State Method WTPH-HCID. This analytical method identified two samples as containing gasoline -range petroleum hydrocarbons. The two samples were quantified for gasoline -range petroleum hydrocarbons by Washington State Method WTPH-G and for benzene, ethylbenzene, toluene, and total xylenes (BETX) by United States Environmental Protection Agency (USEPA) Method 8020.

Vivian Gull Industries, Inc. April 1, 1996 Page 2 AGI TECHNOLOGIES The four monitoring wells were developed and a groundwater sample collected for analytical chemistry analysis on March 11, 1996. The samples were submitted to ATI for screening of gasoline - range, diesel -range, and oil -range petroleum hydrocarbons using USEPA Method 8015 Modified. This analytical methods identified three samples as containing gasoline -range petroleum hydrocar- bons. These samples were quantified for gasoline -range TPH by Washington State Method WTPH-G and for BETX by USEPA Method 8020. The elevation of each monitoring well was surveyed and water levels were collected for the preparation of a groundwater surface map. Groundwater elevation data are presented in Table 1. Water levels collected on March 14 and 20, 1996 indicate the direction of groundwater flow is generally to the south. The expected groundwater flow direction is to the north-northeast based on the presence of the nearby Green River. Analytical laboratory results for soil and groundwater samples are summarized in Tables 2 and 3. Copies of AGI's quality assurance review and analytical laboratory reports are contained in Attachment 2. The analytical laboratory results indicate a release has occurred from the former underground storage tank system at the site. Pursuant to Washington Administrative Code 173-340-450 of the Model Toxics Control Act, the release must be reported to Ecology. Sincerely, AGI Technologies Lance E. Peterson, P.G.

The relative percent difference (RPD) for gasoline recovery in one of the associated duplicates was outside ATI established control limits. The RPD for diesel recovery in this same sample was within limits. The RPD's for the other duplicate sample associated with this extraction batch were within established limits. Since WA DOE WTPH-HCID is a qualitative identification method, and positive results were found in both the original extract and the duplicate that were out of limits, no further action was taken. All other corresponding quality assurance/quality control (QA/QC) parameters were within ATI established control limits 10 117 AnalyticalTechnologies,Inc.

The method blanks were free of all analytes of interest. All surrogate percent recoveries were within ATI control limits with the exception of bromofluorobenzene in sample 603035-3 (MW3), which was out of limits due to high levels of target -analytes in the sample. The matrix spike/matrix spike duplicate (MS/MSD) recoveries and relative percent differences (RPDs) were within ATI control limits. The blank spike (BS) recoveries were within ATI control limits. All other associated quality assurance and quality control (QA/QC) parameters were within the ATI established control limits. All analytical hold times - were met. LAnalyticalTechnologies,Inc.
