This property has a documented history as a gasoline service station going back to 1981. 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 gasoline dispensing facility since approximately 1981, when its first-generation underground storage tank system was installed. A gasoline release was reported in 1993, triggering quarterly groundwater monitoring that has continued since 1994. Remediation under the Standard Cleanup program has included multiple phases of soil excavation — 100 tons in 1995, 1,250 tons in 2015, and 75 cubic yards in 2021 — along with removal of approximately 17,500 gallons of impacted groundwater, in-situ treatment via BOS-200 injections in 2018, and installation of an oil water separator in 2021. The site remains in active commercial use as a 7-Eleven convenience store and fueling facility. 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 gasoline release at this property originated from underground storage tanks installed in 1981, five years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. Remediation costs have accumulated over nearly three decades — soil excavation, groundwater recovery, in-situ bioremediation, and long-term monitoring — with cleanup still underway and additional expenditures ahead. Historical carriers who issued CGL policies covering this facility during the early 1980s may be obligated both to reimburse past remediation costs and to fund the remaining cleanup work.
