This property has a documented history as a gasoline service station going back to 1920. 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 gasoline service station with underground storage tanks dating to the early 1920s, later accompanied by an auto repair shop. Cleanup began in June 1989 with the excavation and removal of multiple USTs and a contaminated trench, followed by groundwater pumping and air sparging from 1994 through 1995 that recovered thousands of gallons of petroleum-affected groundwater. Remediation efforts, including monitored natural attenuation, continued through at least October 2012 under the Voluntary Cleanup Program, and cleanup work remains ongoing. 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.
Gasoline-range petroleum hydrocarbons and BTEX contamination at this site originated from underground storage tanks installed and operated more than six decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Over two decades of documented remediation expenditures — tank removals, soil excavation, groundwater treatment, air sparging, and long-term monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover past cleanup costs and to fund the remediation that remains ahead.
