This property operated as Unocal Service Station 6943 in Everett, with underground storage tanks estimated to have been installed around 1966. Cleanup under the Voluntary Cleanup Program ran from April 1991 through May 2003 and included UST removal, hot spot soil excavation, a biosparging and bioventing pilot test, and extensive quarterly groundwater monitoring. The site received a No Further Action determination for both soil and groundwater contamination. 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.
Petroleum contamination at this former service station originated from underground storage tanks that were in place roughly two decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. Over twelve years of documented remediation expenditures — tank removal, soil excavation, bioremediation testing, and long-term groundwater monitoring — were incurred to address releases tied to those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's operational window may still be obligated to recover those cleanup costs.
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.
