This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as Gull Service Station No. 611, a retail gasoline station equipped with three single-walled underground storage tanks totaling 32,000 gallons of capacity — dispensing unleaded, mid-grade, and premium unleaded gasoline from two pump islands. A gasoline fuel release was discovered in September 1997, prompting cleanup under the Voluntary Cleanup Program that has included removal of all three USTs and associated piping, excavation of hydrocarbon-impacted soils and exploratory test pits, and a multi-year groundwater monitoring program in place since 1997. The service station is now closed and cleanup work is ongoing. 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 contamination at this property originated from underground storage tanks that were in service well before 1986 — lead detected in soil and groundwater samples is consistent with leaded gasoline sales typical of that era. Occurrence-based CGL policies issued to the station's operators during those pre-1986 years carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — tank removals, soil excavation, and decades of groundwater monitoring — along with further cleanup efforts still planned represent costs that historical carriers may be obligated both to recover and to fund going forward.
