This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property operates as an active gasoline fueling station and convenience store in Shelton, Washington. Three gasoline underground storage tanks were removed in 1989, followed by heating oil and waste oil tanks in 1990, with approximately 20 tons of petroleum-impacted soil excavated during the 1989–1991 cleanup period. Groundwater contamination was addressed through more than a decade of quarterly monitoring under a monitored natural attenuation approach, and the site achieved No Further Action status through the Voluntary Cleanup Program. A restrictive covenant may be required for residual soil contamination remaining on the property. 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 — including gasoline-range hydrocarbons and lead — originated from underground storage tanks that were installed and operated well before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation costs spanning tank removals, soil excavation, and over ten years of groundwater monitoring represent expenditures tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the period these tanks were in service 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.
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.
