This property has a documented history as a gasoline service station going back to 1982. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property was first developed as a gasoline service station in 1982, operating as ARCO Station 5567 with four 10,000-gallon underground storage tanks dispensing leaded and unleaded gasoline. Cleanup under the Voluntary Cleanup Program has included removal of all four USTs, excavation of 545 cubic yards of contaminated soil, recovery of 66,000 gallons of contaminated groundwater, air sparging, sulfate injection, and installation of a remedial system with ongoing semi-annual groundwater monitoring. The property continues to operate as an AM/PM ARCO retail gasoline station. 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 beginning in 1982 — four years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures — tank removals, large-scale soil excavation, tens of thousands of gallons of groundwater recovery, active treatment systems, and years of monitoring — are tied directly to releases from those pre-1986 fueling operations. With cleanup still underway, historical carriers who issued CGL policies during the 1982–1986 window may be obligated both to reimburse past costs and to fund the remediation work that remains.
