This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property housed underground storage tanks for gasoline and diesel fuel, with tank installations dating to 1950 and 1974. In March 1991, two tanks — a 2,000-gallon gasoline tank and a 300-gallon diesel tank — were excavated and removed along with contaminated soil, which was disposed of offsite. The contamination originated from a leaking line connecting one of the tanks to its pump dispenser. The site remains under ongoing assessment, with further groundwater and soil testing recommended in 2006 and a site hazard assessment noted as recently as 2025. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
Petroleum contamination at this property traces directly to underground storage tanks installed in 1950 and 1974 — decades within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs to date, including tank removal, soil excavation, offsite disposal, and continuing site assessment spanning more than three decades, represent expenditures that historical carriers may be obligated both to reimburse and to fund as cleanup work continues.
