This property has a documented history as a gasoline service station predating 1986. 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 with multiple underground storage tanks. In 1989, removal of three USTs revealed physical evidence of gasoline leakage, and during excavation three additional older tanks of unknown origin were discovered — two had been closed in place with sand and had large holes in their bottoms, indicating they were the source of releases dating well before the 1989 removal. Cleanup from December 1989 through April 1990 included removal of all six tanks and excavation of approximately 220 cubic yards of gasoline-contaminated soil, which was transported off-site for bioremediation. The property currently operates as a gas station with two sets of pump islands and a convenience store. 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 discovery of older, deteriorated underground storage tanks with large holes — tanks whose origin was unknown even at the time of excavation — points to gasoline releases that began decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs at this site — tank removals, soil excavation, off-site bioremediation — arose from contamination tied directly to those long-running pre-1986 operations. Historical carriers who issued CGL policies to the operators during that window may still be obligated to recover those cleanup expenditures and to fund any further remediation the site requires.
