This property has a documented history as a gasoline service station going back to 1940. 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 gasoline station since at least 1940, when city directories recorded Art's Shell Service at the location, with a 1949 Sanborn Fire Insurance Map confirming gas and oil storage on site. ARCO redeveloped the property in 1984 as a retail gasoline and diesel fuel station with a convenience store, installing three 12,000-gallon underground storage tanks and distribution piping placed in service by 1985. Groundwater monitoring across multiple wells has confirmed petroleum hydrocarbon contamination — including TPH-g, benzene, ethylbenzene, and total xylenes — exceeding MTCA Method A cleanup levels, with the groundwater plume migrating south toward the Duwamish River roughly 525 feet from the site. The USTs were removed in 2002 and cleanup is ongoing under the Voluntary Cleanup Program. 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.
Gasoline storage and dispensing operations at this property span from at least 1940 through ARCO's 1984 redevelopment and beyond — more than four decades of petroleum handling squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The confirmed benzene and petroleum hydrocarbon contamination in groundwater, now migrating toward the Duwamish River, represents exactly the type of gradual, ongoing release those pre-1986 policies were written to cover. Historical carriers who insured operations at this site during that window may bear obligations both to recover past remediation expenditures and to fund the cleanup work the Voluntary Cleanup Program still requires.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
