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 formerly served as the site of a small store that sold gasoline, with two underground storage tanks supporting fuel sales. During a later remodel and expansion of the residence now occupying the property, strong gasoline odors led to the discovery of contamination from the former tanks. Cleanup activities included the excavation and removal of both USTs and approximately 20 cubic yards of contaminated soil in 2001, followed by in-situ bioremediation through injection of soil conditioner and nutrients. The site was enrolled in the Voluntary Cleanup Program from 2003 until receiving an inactive determination in 2007. 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 petroleum contamination at this property originated from underground storage tanks that supported gasoline sales well before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation costs — tank removal, soil excavation, and bioremediation — were incurred to address a slow release from those pre-1986 operations. Historical carriers who issued CGL policies during the period the tanks were in service may be obligated both to recover those past cleanup expenditures and to fund any remaining remediation the site requires.
