This property has a documented history as a gasoline service station going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The former Arco Service Station on Parcel B of this three-parcel property was constructed in 1957 and operated with two 4,000-gallon and one 275-gallon underground storage tanks plus a hydraulic hoist until the building was demolished in the early 1970s; the parcel has been vacant ever since. Cleanup under the Voluntary Cleanup Program has included decommissioning and sand-filling those USTs, installing a Volclay-bentonite panel and a high-density polyethylene vapor shield for soil containment, and recording an Environmental Covenant that mandates vapor sampling every five years. The broader site encompasses adjacent parcels with former dry cleaning and auto repair operations, but petroleum impacts from the service station are the primary driver of ongoing remedial oversight. 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 TPH-G contamination documented in soil beneath this property originated from underground storage tanks installed in 1957 — nearly three decades before 1986, the year occurrence-based Commercial General Liability policies began to routinely exclude pollution claims. Operators of the Arco station carried commercial liability coverage throughout that pre-1986 window, when such policies were written without effective pollution exclusions in Washington. The UST decommissioning, engineered containment systems, and court-recorded covenant requiring decades of vapor monitoring represent remediation expenditures that historical carriers whose policies were in force during the station's operation may be obligated both to recover and to fund going forward.
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.
