This property has a documented history as a gasoline service station going back to 1957. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a retail fuel station since 1957, first with underground storage tanks installed that year and additional tanks added in 1974. Five USTs were removed in 1986, and extensive remediation followed under the Voluntary Cleanup Program — including excavation of approximately 1,168 tons of petroleum-impacted soil in 2005–2006, recovery of over 49,000 gallons of contaminated groundwater and floating hydrocarbons between 1989 and 2005, and groundwater monitoring spanning from 1991 through 2013. The property continues to operate as an ARCO AM/PM retail fuel station and convenience store. 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 in 1957 and 1974 — nearly three decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. Lead detected in groundwater monitoring wells as far back as 1991 points to releases of leaded gasoline during the pre-1986 operational window. The documented remediation expenditures — tank removals, large-scale soil excavation, years of groundwater recovery and monitoring — represent costs that historical carriers who issued CGL policies during those early decades of operation may be obligated both to reimburse and to fund as cleanup continues.
