This property has a documented history as a gasoline service station going back to 1970. 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 and car wash since 1970, with two underground storage tanks for gasoline and diesel installed that year and four additional gasoline USTs installed in 1971. Cleanup under the Voluntary Cleanup Program has included installation of groundwater monitoring wells in 2003, quarterly monitoring through at least 2016, and multiple rounds of in-situ chemical oxidation — 300 pounds of oxygen release compound injected in 2004, 180 pounds in 2007, and a 510-pound RegenOx pilot test in 2009. Cleanup work is ongoing. 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 starting in 1970 — sixteen years before occurrence-based CGL policies gave way to claims-made forms with effective pollution exclusions. The documented remediation expenditures here, including well installation, more than a decade of quarterly groundwater monitoring, and repeated chemical oxidation treatments, represent costs tied directly to releases from those pre-1986 fueling operations. Historical carriers who wrote CGL policies covering this property during that window may be obligated both to recover past cleanup costs and to fund the remediation still underway.
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.
