This property has a documented history as a gasoline service station going back to 1975. 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 retail gasoline service station from approximately 1975 to 2006, equipped with three underground storage tanks, two fuel-dispensing pump islands, and associated product delivery piping. Cleanup activities have included the removal of all three USTs and 591 tons of contaminated soil in 2006, followed by installation of a soil and groundwater remediation system in 2008 incorporating groundwater recirculation, soil vapor extraction, and air sparge technologies. That system remains in operation, with quarterly groundwater monitoring ongoing and additional remediation components including a PlumeEater unit. 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 and operated from 1975 — more than a decade before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The remediation expenditures already incurred here — tank removals, large-scale soil excavation, and years of active groundwater and vapor treatment — along with the costs of continued system operation and monitoring, represent obligations that historical carriers who wrote CGL policies during the 1975–1986 window may be required both to reimburse and to fund going forward.
