This property has a documented history as a gasoline service station going back to 1975. 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 convenience store and gas station since at least 1975, with petroleum distribution from underground storage tanks beginning by 1979. Four USTs — including two 4,000-gallon unleaded gasoline tanks, one 6,000-gallon unleaded gasoline tank, and one 4,000-gallon leaded gasoline tank — were installed circa 1979 and have been the source of documented contamination in soil, groundwater, and soil vapor. Cleanup under the Voluntary Cleanup Program has included multiple phases of UST removal and soil excavation in 1994 and 2006, installation and operation of a groundwater treatment system beginning in 1994, groundwater monitoring from 2017 through 2019, and installation of a sub-slab depressurization system in 2023 to address vapor intrusion. The site continues to operate as a gas station and mini mart. 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 property traces to underground storage tanks installed and operated starting in 1979 — seven years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The carriers who issued CGL policies during those pre-1986 fueling operations may still bear obligation for the remediation costs already incurred over three decades of cleanup — tank removals, soil excavation, groundwater treatment, long-term monitoring — as well as the ongoing vapor-intrusion mitigation the site now requires.
