This property has a documented history as a gasoline service station going back to 1983. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was developed as a gasoline station and convenience store in 1983, with an underground storage tank system comprising four USTs totaling 42,000 gallons of gasoline and diesel capacity. Cleanup under the Voluntary Cleanup Program has included excavation of 921 tons of contaminated soil, removal of 6,000 gallons of impacted groundwater, operation of soil vapor extraction and air sparging systems, and bioremediation using 240 pounds of ORC-A. Residual contamination has been capped under an environmental covenant, and quarterly groundwater monitoring with periodic reviews remains ongoing. 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 leaking underground storage tanks installed in 1983 — three years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures — nearly a thousand tons of soil removal, groundwater recovery, vapor extraction, bioremediation, institutional controls, and years of ongoing monitoring — were incurred to address releases tied directly to those pre-1986 fuel storage operations. Historical carriers who issued CGL policies covering this station during that window may be obligated both to reimburse past cleanup costs and to fund the monitoring and institutional controls that continue today.
