This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a Shell-branded service station, with facilities that included a station building, two dispenser islands, three 10,000-gallon gasoline underground storage tanks, and one 10,000-gallon diesel underground storage tank. A petroleum release impacting soil and groundwater was reported to Ecology in 1989, and all four USTs were decommissioned and removed in June 1990. The site is currently enrolled in Washington's Voluntary Cleanup Program, with cleanup ongoing. 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.
The petroleum contamination here originated from underground storage tanks that, based on their documented removal in June 1990 and a service life extending well before 1986, were installed and in operation during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Those pre-1986 policies may still be enforceable against the historical carriers who covered this facility's operations — covering not only the remediation costs already incurred since the 1989 release report but also the forward-looking expenses associated with completing the active cleanup now underway.
