This property has a documented history as a gasoline service station going back to 1984. 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 gasoline filling station for approximately 20 years beginning around 1984, dispensing unleaded gasoline from two 10,000-gallon underground storage tanks at fuel islands on the site. Cleanup activities have included removal of those USTs, excavation and disposal of more than 526 tons of petroleum-contaminated soil, and pumping of 3,272 gallons of impacted groundwater for off-site treatment. Monitoring wells were installed and alternative drinking water was provided to affected parties due to a persistent contamination plume, with ongoing groundwater monitoring and potential future treatment still recommended. The site no longer operates as a gasoline filling station. 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 property traces to underground storage tank operations that began around 1984 — before the 1986 threshold at which occurrence-based Commercial General Liability policies began routinely incorporating effective pollution exclusions. The documented remediation record here — UST removals, large-scale soil excavation, groundwater recovery, long-term monitoring, and provision of alternative drinking water to affected off-site wells — represents both costs already incurred and expenditures that a persistent groundwater plume may yet require. Historical carriers whose CGL policies were in effect during the station's pre-1986 operating years may be obligated both to recover past cleanup costs and to fund the treatment work still to come.
