This property has a documented history as a gasoline service station going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gasoline fueling station since the 1970s, with underground storage tanks installed by August 1970 — including a 6,000-gallon leaded gasoline UST and two 8,000-gallon unleaded gasoline USTs. Historical cleanup activities have included the removal of three USTs totaling 22,000 gallons of capacity and excavation and off-site disposal of 180 tons of petroleum-contaminated soil. A subsequent release from an existing UST, reported in 2022, initiated ongoing quarterly groundwater monitoring and product-removal efforts that continue today. 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 from 1970 — more than fifteen years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures to date — tank removals, soil excavation, and now multi-year groundwater monitoring and product recovery from the 2022 release — represent cleanup costs tied directly to infrastructure that was in service during the pre-1986 policy window. Historical carriers who wrote CGL coverage for the fueling station during that period may be obligated both to reimburse past remediation costs and to fund the ongoing monitoring and cleanup work ahead.
