This property has a documented history as a gasoline service station going back to 1933. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
A gasoline service station was constructed at this property in 1933 and operated as a Mobil station until at least 1969, with facilities including two pump islands and multiple underground storage tanks ranging from 550 to 8,000 gallons in capacity. Cleanup under the Voluntary Cleanup Program has involved tank removals, soil excavation, groundwater treatment through in-well stripping, dual-phase extraction, and light petroleum hydrocarbon recovery, as well as soil vapor extraction system testing and operation. Ongoing remediation includes annual inspections of containment caps and vapor barriers, continued groundwater monitoring, and a proposed major excavation estimated at $950,000. 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 traces to underground storage tanks installed and operated beginning in 1933 — more than five decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation expenditures already incurred, combined with the $950,000 excavation still ahead, represent substantial cleanup costs tied directly to releases from those pre-1986 fueling operations. Historical carriers who wrote CGL coverage for the station's operators during that long operational window may be obligated both to reimburse past remediation costs and to fund the cleanup work that remains.
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.
