This property has a documented history as a gasoline service station going back to 1950. 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 fuel service station and auto repair shop for approximately 42 years, from 1950 through 1992. Four underground storage tanks — two 8,000-gallon tanks installed in 1950 holding leaded and unleaded gasoline, and two 6,000-gallon tanks installed in 1978 holding unleaded gasoline and diesel — were removed in 1992 along with approximately 138 cubic yards of petroleum-contaminated soil. Subsequent cleanup under the Voluntary Cleanup Program included installation and operation of groundwater monitoring wells, periodic groundwater sampling, and purging activities extending from 2001 through 2011. 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 installed in 1950 and 1978 — decades before the 1986 cutoff after which occurrence-based Commercial General Liability policies ceased reliably covering pollution claims. The documented remediation costs spanning two decades — tank removals, soil excavation, well installation, and long-term groundwater monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during the 1950-through-1985 operational window may be obligated both to recover past cleanup expenditures and to fund remediation still ahead.
