This property has a documented history as a gasoline service station going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gasoline service station since at least 1967, when the convenience store was built; underground storage tanks were installed by the mid-1970s and dispensed both leaded and unleaded gasoline until the UST system was removed in 1991. Cleanup under a Standard Cleanup program has included excavation of 620 cubic yards of contaminated soil, a groundwater pump-and-treat system with granular activated carbon, a groundwater interception trench, air sparging, soil vapor extraction, and intrinsic bioremediation — with continuous groundwater and compliance monitoring ongoing. The site is currently in performance monitoring following construction of the remedy. 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 that were in operation from the early 1970s through 1991 — more than a decade before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The remediation expenditures documented here — tank removal, large-scale soil excavation, years of pump-and-treat operations, vapor extraction, and ongoing monitoring — represent costs directly traceable to those pre-1986 fuel-dispensing operations. Historical carriers who issued CGL policies to Time Oil Co. during the period those tanks were leaking may still be obligated to recover past cleanup costs and fund the monitoring that continues today.
