This property has a documented history as a gasoline service station going back to 1953. 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 Chevron gasoline station with underground storage tanks and fuel dispensers dating to at least 1953. Cleanup under the Voluntary Cleanup Program has included removal of at least one 1,000-gallon underground storage tank and other tanks, soil excavation, and installation of soil vapor extraction wells. Annual groundwater monitoring has been ongoing since at least 1995, with petroleum hydrocarbons and lead detected across multiple monitoring wells. 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.
Fuel storage and dispensing operations at this site began more than three decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The detection of lead in groundwater — a marker of leaded gasoline use phased out before 1986 — ties the contamination directly to that pre-1986 operational window. Documented remediation costs already incurred, from tank removals and soil excavation to decades of groundwater monitoring, along with cleanup work still underway, represent expenditures that historical carriers may be obligated both to recover and to fund going forward.
