The Pollution Liability Insurance Agency (PLIA) invites the public to comment. This is a proposal to remove Bill’s Garage (“Site”) from the Department of Ecology’s Hazardous Sites List pursuant to WAC 173-340-330(10).

The Bill’s Garage property was formerly used as an automotive service and gas station from 1920 until 2006. After the business closed in 2006, petroleum contamination was discovered as part of the pending property sale. Since 2006, no businesses have operated on the property. Between 2006 and 2018, the Site underwent several remedial investigations. In October 2018, a source removal action was conducted to take out the former underground storage tanks. As much as practicable, petroleum-impacted soil was also removed. A remedial action of in-situ chemical oxidation, sorption, and enhanced biodegradation was selected and performed to treat contaminants in the soil and groundwater on the Site.

The cleanup actions performed on the Site meet the substantive requirements of the Model Toxics Control Act (MTCA) regulations for site closure with the conditions of a protective environmental covenant. An environmental covenant has been recorded with the Jefferson County Auditor’s Office to control subsurface activities on the Site and minimize potential exposure during monitored natural attenuation of soil and, as appropriate, groundwater impacts.

PLIA performed regulatory oversight of the Site under the agency’s Technical Assistance Program (TAP). Based on the Site review, PLIA determined that the Site meets the substantive requirements of the state clean up regulations, Chapter 173-340 WAC Model Toxics Control Act, and no longer poses a threat to human health or the environment.
