This property has a documented history as a gasoline service station going back to 1973. 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 and diesel fueling station, with four single-wall, asphalt-coated steel underground storage tanks totaling 32,000 gallons — individual tanks for diesel, super-unleaded, normal-grade unleaded, and mid-grade unleaded — removed over three days in late September and early October 1998. Remediation has included excavation of 550 tons of impacted soil from the tank cavity and 270 tons from the dispenser area, removal of concrete sumps and associated fuel piping, pumping of 100 gallons of contaminated groundwater, and installation of an Oxygen Release Compound system. Multi-year quarterly groundwater monitoring has continued, and cleanup work 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.
The single-wall, asphalt-coated steel tanks removed from this property in 1998 are consistent with installation in the early 1970s — more than a decade before 1986, when occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. Detection of total lead in the groundwater further confirms that leaded-gasoline operations, phased out by the mid-1980s, were ongoing at this site during the pre-1986 policy window. The documented remediation costs here — large-scale soil excavation, groundwater recovery, in-situ bioremediation, and years of monitoring — represent expenditures that historical CGL carriers whose policies were in force during those operations may be obligated both to recover and to fund going forward.
