The Pollution Liability Insurance Agency (PLIA) invites the public to comment. This is a proposal to remove the 7-Eleven Store 22261 (Site) from the Department of Ecology’s Hazardous Sites List pursuant to WAC 173-340-330(10).
The 7-Eleven Store operates about 350 feet east of the Hoquiam River in Hoquiam, Washington. Gasoline from three 10,000-gallon underground storage tanks (USTs) on the property leaked into the soil and groundwater. Data from soil borings and groundwater quality monitoring wells show that Site contamination is limited to upland locations; the surface water of the Hoquiam River was not impacted. The polluted soil was removed, and groundwater was treated. This is followed by four consecutive performance monitoring, that show groundwater quality below the Method A unrestricted land use at the points of compliance (POC) wells. The three 10,000-gallon USTs were replaced with two new 15,000-gallon double wall fiberglass USTs.
PLIA performed regulatory review of the Site under the Petroleum Technical Assistance Program (PTAP). Based on the Site review and groundwater and vapor monitoring results, PLIA determined that the Site meets the substantive requirements of the Model Toxics Control Act. The Site no longer poses a threat to human health or the environment.
