This property has a documented history as a gasoline service station going back to 1935. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was first developed as a gasoline service station in 1935, with pump islands and fuel storage USTs operating continuously through 1969. Cleanup under the Voluntary Cleanup Program has been ongoing since at least 1999, with major remediation from 2001 to 2005 including removal of multiple underground storage tanks and excavation of thousands of tons of contaminated soil. Groundwater treatment has involved LNAPL bailing, granular activated carbon filtration, and surfactant-enhanced recovery, with quarterly groundwater monitoring continuing through at least 2025. 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 gasoline storage and dispensing operations that began in 1935 — more than five decades before occurrence-based CGL policies ceased covering pollution claims. Over twenty-five years of documented remediation expenditures, from large-scale soil excavation and tank removal to ongoing groundwater treatment and monitoring, trace directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the 1935–1969 operational window may be obligated both to recover past cleanup costs and to fund the remediation work that remains ahead.
