This property has a documented history as a gasoline service station going back to 1974. 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 Chevron service station with three 10,000-gallon gasoline underground storage tanks and two 1,000-gallon used oil and heating oil tanks, with fuel dispensed at two islands on the northern portion of the site. Cleanup under the Voluntary Cleanup Program included excavation and removal of all five USTs totaling 32,000 gallons, removal of hydraulic hoists and an oil/water separator, excavation and off-site disposal of approximately 208 tons of petroleum-impacted soil, and air sparging treatment of 20,000 gallons of contaminated groundwater. Groundwater monitoring continued from at least 2002 through 2014, and an environmental covenant is required on the property due to residual contamination. 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 presence of leaded gasoline constituents in soil around the former USTs and fuel dispensers places this station's operations squarely in the pre-1986 era, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removals, large-scale soil excavation, groundwater treatment, and over a decade of monitoring — were incurred to address petroleum releases tied directly to those historical fueling operations. With cleanup still underway and an environmental covenant signaling ongoing obligations, the historical carriers who covered this station during its pre-1986 operating window may be obligated both to recover past costs and to fund the remaining remediation.
