This property has a documented history as a bulk fuel distribution terminal 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 served as a petroleum bulk storage and distribution facility for aviation fuels from at least 1950 through 1984. Union Oil operated three 8,000-gallon steel underground storage tanks containing aviation gasoline from 1950 to 1984, and Shell Oil installed eight additional steel USTs for jet fuel and aviation gasoline from 1954 to 1984; both companies also operated loading racks on-site. All tanks were decommissioned by October 1984 and removed in 1985, but soil and groundwater contamination attributed to the former aviation fueling operations was subsequently documented through investigation. Ongoing cleanup under the Voluntary Cleanup Program has included soil excavation and off-site disposal of petroleum- and VOC-contaminated soils, product recovery wells, hydraulic control, groundwater dewatering, installation of a soil vapor extraction system, a planned barrier wall, and multi-year monitoring. 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.
Aviation fuel storage and distribution at this property began in 1950 — more than three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The contamination plume has been explicitly traced to the former Shell and Union Oil UST installations, confirming that the release originated from pre-1986 operations rather than any recent incident. Shell Oil, Union Oil, and the property owner each may have held CGL policies during those decades-long operational windows that remain enforceable today against the documented costs of excavation, groundwater recovery, vapor extraction, and the remediation work still underway.
