A Unocal gasoline service station was established at this property in 1960, equipped with three steel underground storage tanks, a waste oil tank, and hydraulic hoists. The original USTs were replaced in 1983, and by 1990 elevated concentrations of total petroleum hydrocarbons (TPH-G) and tetrachloroethylene (PCE) had been detected in groundwater above Method A cleanup levels. Groundwater remediation under the Voluntary Cleanup Program included hydrogen release compound (HRC) injections performed in 2000, and the site has since achieved No Further Action status. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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.
This gasoline service station operated continuously from 1960 — more than two decades before 1986, when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion. The petroleum and solvent contamination discovered in groundwater, and the remediation costs incurred to address it — including groundwater treatment and long-term monitoring through to site closure — arose from operations that began squarely within that pre-1986 policy window. Historical carriers who covered the station during its 1960s-through-1980s operational period may still be obligated to respond to those documented cleanup expenditures.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
