This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a gasoline station from the 1950s through the early 1990s, with multiple underground storage tanks serving retail fuel sales. The tanks were removed in 1992, and extensive petroleum-impacted soil excavation followed in 2001, reaching six feet below grade. Groundwater remediation has included aeration and an air sparging system with planned bio-enhancement, along with installation of a passive vapor collection system and ongoing quarterly and biannual groundwater monitoring. A convenience store currently operates on the property. 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 that were installed and operated for decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The documented remediation costs — tank removals, large-scale soil excavation, groundwater treatment systems, vapor collection, and years of ongoing monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's operational window may be obligated both to recover past cleanup expenditures and to fund the remediation work that continues today.
