This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property was developed as a service station in 1964, replacing a prior residential use dating to 1936. The original underground storage tanks — gas and diesel — were decommissioned or replaced in 1989 after a release was discovered in 1988. Cleanup under the Voluntary Cleanup Program has included UST removal, excavation of over 1,100 cubic yards of petroleum-impacted soil, treatment of three million gallons of groundwater through an extraction system, application of an Oxygen Release Compound, and multi-year groundwater monitoring from at least 1993 through 2015. The site continues to operate as a Shell-branded wholesale fuel retail facility. 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 originated from underground storage tanks installed and operated beginning in 1964 — more than two decades before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures here — tank removal, large-scale soil excavation, a multi-million-gallon groundwater extraction campaign, and over twenty years of monitoring — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the 1964–1986 operational window may be obligated both to recover past cleanup costs and to fund remediation still ahead.
