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 operated as ARCO Facility #1128, a retail gasoline station and convenience store equipped with four 10,000-gallon underground storage tanks and three fuel dispensers. Cleanup under the Voluntary Cleanup Program has included the decommissioning and replacement of seven USTs in 1991, excavation of approximately 550 cubic yards and 180 tons of impacted soil, and operation of a soil vapor extraction system from 1991 through 1999 that recovered 9,624 pounds of volatile hydrocarbons. Additional remediation has involved hydrogen peroxide injection, groundwater pump testing for a proposed two-phase extraction system, ongoing groundwater monitoring, and the filing of environmental restrictions on the property. 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 originated from underground storage tanks that were in service well before their 1991 decommissioning, and the detection of total lead in groundwater samples points to operations dating to the era of leaded gasoline — phased out by the mid-1980s. Occurrence-based CGL policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — tank removal, large-scale soil excavation, nearly a decade of vapor extraction, and ongoing monitoring — represent costs that historical carriers may be obligated both to reimburse and to continue funding as cleanup work proceeds.
