This property has a documented history as a gasoline service station going back to 1969. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gasoline service station since at least the late 1960s, with underground storage tanks for gasoline and diesel, fuel dispensers, and hydraulic hoists serving the site over that period. Cleanup under the Voluntary Cleanup Program included the 1994–1995 excavation and removal of multiple USTs — including five previously undocumented tanks — an oil/water separator, and hydraulic hoists, with over 2,250 cubic yards of contaminated soil removed and approximately 56,000 gallons of petroleum-affected groundwater pumped and treated. Bioremediation was enhanced using ammonium sulfate in backfill material, and multi-year groundwater monitoring continued from 2003 through 2007. The property remains an active gasoline service station with three USTs in service and a convenience store on site. 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 — including lead indicative of historical leaded gasoline use — traces to underground storage tank operations that began decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures here are substantial: large-scale tank removal, thousands of cubic yards of soil excavation and off-site disposal, groundwater recovery, bioremediation, and years of monitoring. Historical carriers who issued CGL policies during the pre-1986 operational window may be obligated both to recover those past cleanup costs and to fund remediation that remains ahead.
