This property has a documented history as a gasoline service station going back to 1950. 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 service station from the 1950s until the late 1970s, with three gasoline underground storage tanks (8,000-, 6,000-, and 3,000-gallon capacity) and a 500-gallon waste oil tank serving two service bays. The USTs were removed when the station was demolished, and an additional 550-gallon fuel oil tank was removed in 2005. Remediation under the Voluntary Cleanup Program has included excavation and disposal of 2,415 tons of petroleum-contaminated soil, recovery of 4,600 gallons of contaminated groundwater, installation of a soil vapor barrier, application of a bioremediation bacteria blend, and multi-year groundwater and soil vapor monitoring. Cleanup work is 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 property traces directly to underground storage tanks installed and operated during the 1950s through the late 1970s — decades before the 1986 threshold after which CGL policies began excluding pollution claims. Occurrence-based Commercial General Liability policies issued to the operators during that window had no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — thousands of tons of soil removal, groundwater recovery, vapor barrier installation, bioremediation, and ongoing monitoring — represent costs that historical carriers may be obligated both to reimburse and to continue funding.
