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

The property is currently an unpaved lot used as a four-unit self-storage business. Petroleum contamination was discovered at the site in 1996 during the removal and decommissioning of a 675 gallon diesel and gasoline underground storage tank (UST) and a 1,000 gallon diesel UST. Over 43 tons of contaminated soil was removed in 1996 and an additional 63.4 tons of soil was removed in 2019 after the removal of an existing office building. All petroleum-contaminated soil has since been removed from the site. For two consecutive quarters in 2019-2020, four monitoring wells demonstrated that there was no contamination in the groundwater that exceeds state cleanup levels. These results also indicate that surface water and vapor impacts are not an ongoing concern. PLIA performed regulatory review of the Site under the agency’s Petroleum Technical Assistance Program (PTAP). Based on this review and results from soil sampling and groundwater monitoring, PLIA determined that the site met the state’s cleanup standards. The site does not pose a threat to human health or the environment.

PLIA’s review indicates that the Site meets the substantive requirements of the state cleanup regulations, Chapter 173-340 WAC, Model Toxics Control Act. Performance monitoring is complete.  The confirmation monitoring demonstrated that the cleanup actions effectively controlled the Site pollution.
