This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property has operated as a retail gasoline service station since approximately 1971, with underground storage tanks installed as early as 1964 dispensing fuel from pump islands. Cleanup under the Voluntary Cleanup Program included removal of five USTs totaling 50,000 gallons of capacity, excavation and off-site treatment of 1,100 cubic yards of petroleum-contaminated soil, and installation and operation of a Soil Vapor Extraction system with five vapor extraction wells from at least 1991 through approximately 1995. The overall investigation and remediation project spanned 22 years, culminating in a No Further Action determination in 2011. The property continues to operate today as a ConocoPhillips branded fueling facility. 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.
Underground storage tanks at this property were installed in 1964 — more than two decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The petroleum contamination documented here originated from USTs that were in the ground for over 25 years before their removal in 1990, the kind of long-duration, pre-cutoff release those policies were written to address. Twenty-two years of documented remediation expenditures — tank removals, soil excavation, vapor extraction, and long-term monitoring — represent costs that historical carriers who issued CGL policies during the facility's pre-1986 operational window may be obligated to recover.
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.
Recovering Costs from an Older Cleanup
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.
