This property has a documented history as a gasoline service station going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was developed circa 1920 as a gasoline service station and operated by Atlantic Richfield Company (ARCO) until the mid to late 1980s, with seven underground storage tanks for gasoline and diesel on site. Cleanup under the Voluntary Cleanup Program has included two major excavation events — removal of seven USTs and 370 cubic yards of contaminated soil in 1990, followed by additional tank and lift hoist removals and excavation of 912 tons of contaminated soil in 2009. Groundwater remediation through oxygen release compound injections and quarterly monitoring continues as part of an in-situ bioremediation effort. 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 site originated from underground storage tanks installed and operated over six decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Documented remediation costs — including the $67,194 UST closure in 1991, large-scale soil excavations, and ongoing groundwater treatment — represent expenditures that historical carriers who insured ARCO or prior operators during that pre-1986 window may be obligated both to reimburse and to fund as bioremediation work continues.
