This property has a documented history as a gasoline service station going back to 1932. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The property at this Rochester, Thurston County address has been in commercial use since at least 1932, when county records show the original building — housing a fuel station, general store, and residential dwelling — was constructed. The site's underground storage tank system comprised two 500-gallon USTs and one 2,000-gallon UST, served by suction pumps and steel supply lines; soil and groundwater sampling adjacent to the tanks, supply lines, and pump island confirmed TPH-G, benzene, and xylene at concentrations exceeding MTCA Method A cleanup levels. Cleanup work has included removal of the suction pumps and in-place abandonment of all three USTs and associated fuel supply lines, which were filled with inert material. 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.
Fuel dispensing operations at this property began in 1932 — more than five decades before occurrence-based Commercial General Liability policies began routinely excluding pollution claims — and the leaking underground storage tanks that produced the documented soil and groundwater contamination were a direct product of that decades-long operational history. Pre-1986 CGL policies carried by the operators of this fuel station during that extended window had no effective pollution exclusion in Washington and remain enforceable against the releases confirmed here. The remediation costs already incurred — investigation, UST abandonment, and ongoing cleanup — represent expenditures the historical carriers may be obligated both to recover and to fund going forward.
