This property has a documented history as a gasoline service station going back to 1954. 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 Union Oil gasoline service station from 1954 through 1975, after which a commercial building was constructed on the site in 1976. Soil and groundwater sampling confirmed gasoline-range hydrocarbons and lead in excess of Washington State MTCA Method A cleanup levels, attributed to underground storage tanks formerly located at the property. Under the Voluntary Cleanup Program, cleanup activities in 2008 included excavation and disposal of 90 tons of petroleum-contaminated soil and 902 gallons of wastewater. Remediation remains ongoing, with quarterly and bi-annual groundwater monitoring, natural attenuation, and a proposed oxygen-releasing compound injection for expedited groundwater treatment. 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 contamination here — highly weathered gasoline-range hydrocarbons and lead traced directly to underground storage tanks — originated from a Union Oil station that operated for over two decades before 1975, well before 1986 and the era of effective pollution exclusions in Commercial General Liability policies. The documented cost trail spans soil excavation, wastewater disposal, years of groundwater monitoring, and a planned in-situ injection program, all attributable to releases from those pre-1986 operations. Historical CGL carriers whose policies were in force during the 1954–1975 operational window may be obligated both to recover costs already incurred and to fund the remediation work still underway.
