This property has a documented history as a gasoline service station going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gasoline service station since at least 1967, when American Oil leased the site; a service station was visible in a 1969 aerial photograph, and original underground storage tanks were installed in 1971. The facility — later operated under the Unocal and Arco brands — included two 12,000-gallon gasoline USTs, waste oil and heating oil tanks, hydraulic hoists, and two fuel service islands. Cleanup under the Voluntary Cleanup Program has involved UST and hydraulic hoist removal, overexcavation of approximately 380 cubic yards of petroleum-contaminated soil, on-site landfarming, and installation of an Air Sparging/Vapor Extraction System, with quarterly groundwater monitoring ongoing since 1992. 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 fuel storage and dispensing infrastructure installed and operated continuously from 1971 — fifteen years before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. Lead detected in groundwater confirms the use of leaded gasoline during the earliest phase of operations, tying the contamination directly to that pre-1986 window. The documented remediation expenditures — tank removals, large-scale soil excavation, vapor extraction, and more than three decades of groundwater monitoring — represent costs the historical carriers who insured those operations may be obligated both to reimburse and to fund through completion of cleanup.
