This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was in active development from at least 1956 and at some point housed a 1,000-gallon underground storage tank found to contain both gasoline and diesel products, consistent with motor fuel storage at a former gas station on or adjacent to the site. Cleanup activities under the Voluntary Cleanup Program have included removal of that UST and a pilot groundwater pump-and-treat test that processed approximately 700 gallons of petroleum-affected water. Future remediation plans call for quarterly groundwater monitoring and monitored natural attenuation over a three-to-five-year period, with a projected total project cost of $72,240. 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.
The petroleum contamination at this property originates from a former underground storage tank used for gasoline and diesel — a use tied to a site in active operation well before 1986, in an area where UST infrastructure dates as far back as 1920. Occurrence-based CGL policies issued to operators during that pre-1986 window carried no effective pollution exclusion and remain enforceable today. The documented and projected remediation expenditures here — UST removal, pump-and-treat pilot work, and years of quarterly groundwater monitoring — represent costs that historical carriers may be obligated both to recover and to fund going forward.
