Site Description (include site address with street, city, and county; physical description; current and historical uses of site; etc.): The site is located at 29625 Pacific Highway South in Federal Way, King County in an area of mixed residential and commercial properties. It is approximately 0.96 acre in size. A UNOCAL gasoline station was constructed in 1969 and operated till 1990. The site was. then occupied by an automobile sales facility and U-Haul company during the early 1990s. The UNOCAL; gasoline service station building was demolished in 1994195. The current underground storage tanks and fueling system were installed in 1995 as part of the construction for the existing gasoline service station and convenience store. The site slopes steeply downward toward the north-northwest, an undeveloped area covered by vegetation. 2. Describe affected media (soil, groundwater, surface water, sediment, air): Soil was contaminated by petroleum products during the period when UNOCAL gasoline station operated the site. Two 10, 000-gallon gasoline USTs, one 520-gallon waste oil tank and one 550-gallon heating oil tank were removed from the subject site in 1989. The steel gasoline tanks were replaced by two 12,000-gallon double -wall fiberglass - coated steel USTs. The steel waster• oil tank was replaced with'a 520-gallon double -wall fiberglass: -coated steel tank. The steel heating oil tank was removed but not replaced. Petroleum contaminated soil was discovered during the tank removal. Approximately 600 cubic yards of contaminated soil was removed from beneath the gasoline USTs and 100 cubic yards from beneath and in the vicinity of the former waste oil UST. However, soil confirmation samples showed residual contamination in the vicinity of the former waste oil UST excavation area, and it was concluded that removal of the remaining contamination would require removal of the service station building and the new tank. A vapor well was installed in 1990 to monitor the conditions- in the vicinity of the former waste oil tank excavation area. Groundwater was not encountered during any borings which reached 30 feet below ground surface (bgs). It is anticipated that the depth to groundwater at this site is greater than 100 feet. 3. Cleanup method used: ® Method A ❑ Method B (Attempted to utilize Method B Worksheet) 0 -Method C 4. Describe cleanup activities (for each media) and if contamination remains on -site (including conformational sampling/analysis, points of compliance, etc...): The two fiberglass -coated steel gasoline tanks and the fiberglass -coated steel waste oil tank which were installed in 1989 were removed. between December 1990 and January 1991. The product lines and the vapor well were also'removed. Approximately 50 cubic yards of soil were excavated from the waste oil tank excavation area, 50 cubic yards from the gasoline tank excavation area, 10 cubic yards from the product -line excavation and 180 cubic yards of 'soil were removed from the vapor well test pit excavation area. All the contaminated soil was disposed off site. One soil confirmation sample taken at the vapor well excavation pit around the depth of 16 feet showed TPH (heavy oil- range) of 280 mg/kg, which was above the MTCA A cleanup Levels at that time, but is below the current cleanup level of 2000 mg/kg. All the other soil confirmation samples showed compliance with MTCA Method A cleanup requirements. - A Limited Phase If investigation was conducted in the subject site in 2001. All the soil samples showed compliance with MTCA Method A Cleanup Levels for Unrestricted Land Use. "Note: a. Table 1 of appendix A from the Report of Request for Determination of No further Action dated on November 23, 2005 has both performance and confirmation sampling results. b. Remediation was conducted in 1989 and 1991. However, the site owners didn't officially request a No Further Action determination at that time and the site remains on Ecology's Confirmed and Suspected Contaminated Site list. Joe Hickey issued a letter dated on April 22, 1991 for the subject site. Joe stated in his letter that proper procedures were followed regarding the tank removal and site remediation.pursuant to federal and state regulations. Joe also stated that the residual contamination was -insufficient to warrant further action. Noted here MTCA method A Cleanup Levels for TPH has been changed after Joe issued the letter. 5.

Ecology appreciates your initiative in pursuing this administrative option for cleaning up hazardous waste sites, under the Model Toxics Control Act (MTCA), Chapter 70.105D RCW. This letter constitutes an advisory opinion regarding whether further remedial action is necessary at the Site to meet the substantive requirements of MTCA and its implementing regulations, Chapter 70.105D RCW and Chapter 173-340 WAC. Ecology is providing this advisory opinion under the specific authority of RCW 70.105D.030(1)(i) and WAC 173-3407515(5). This opinion does not resolve a person's liability to the state under MTCA or protect a person from contribution claims by third parties for matters. addressed by the opinion. The state does not have the authority to settle with any person potentially liable under MTCA except in accordance with RCW 70.105D.040(4). The opinion is advisory only and not binding on Ecology. �.r11 C i Mr. Yung Ho Han 1/28/2006 Page 2 Ecology's Toxics Cleanup Program -has reviewed the following information regarding the Site: 1.

The current underground storage tanks and fueling system were installed in 1995 as part of the construction for the existing gasoline service station and convenience store. The site slopes steeply downward toward the north-northwest, an undeveloped area covered by vegetation. Soil was contaminated by petroleum products during the period when UNOCAL gasoline station operated the site. Two 10, 000-gallon gasoline USTs,-one 520-gallon waste oil tank and one 550-gallon heating oil tank were removed from the subject site in 1989. The steel gasoline tanks were replaced by two 12,000-gallon double -wall fiberglass - coated steel USTs. The steel waster oil tank was replaced with a 520-gallon double -wall fiberglass -coated steel tank. The steel heating oil tank was removed but not replaced. Petroleum contaminated soil -was discovered during the tank removal. Approximately 600 cubic yards of contaminated soil was removed from beneath the gasoline USTs and 160 cubic yards from beneath and in the vicinity of the former waste oil UST. However, soil confirmation samples showed residual contamination in the vicinity of the former waste oif UST excavation area, and it was concluded that removal of the remaining contamination would require removal of the service station building and the new tank. A vapor well was installed in 1990 to monitor the conditions in the vicinity of the former. waste oil tank excavation area. Groundwater was not encountered during any borings which reached 3 0 feet below ground surface (bgs), It is anticipated that the depth to groundwater at this site is greater than 100 feet. The two fiberglass -coated steel gasoline tanks and the fiberglass -'Coated steel waste oil tank which were installed in 1989 were removed between December 1990 and'January 1991. The product lines and the vapor well were also removed. Approximately 50•cubic yards of soil were excavated from the waste oil tank excavation area, 50 cubic yards from the gasoline tank excavation area, 10 cubic yards from the product line excavation and 180 cubic yards of soil were removed from the vapor well test pit excavation area. All the contaminated soil was disposed off site. One soil confirmation sample taken at the vapor well excavation pit around the depth of 16 feet showed TPH (heavy oil. range) of 280 mg/kg, which was above the MICA A cleanup Levels at that time, but is below the current cleanup level of 2000 mg/kg. All the other soil confirmation samples showed compliance with MTCA Method A cleanup requirements. A Limited Phase R investigation was conducted in the subject site in 2001. All the soil samples showed compliance with MICA Method A Cleanup Levels for Unrestricted Land Use.
