This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as Tesoro Service Station #62055, a gasoline fueling facility in Kent, King County. Groundwater beneath the site was found to contain gasoline-range hydrocarbons and BTEX constituents, attributed to small surface gasoline releases during routine station operations. Cleanup under the Voluntary Cleanup Program included a multi-year groundwater monitoring program from 2001 through 2003, during which oxygen-releasing compounds were injected into on-site wells to enhance natural biodegradation. The site has since received a No Further Action determination from Ecology. 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.
Groundwater monitoring at this site included analysis for total lead — a constituent of concern tied to leaded gasoline, which was phased out of use by 1986. That analytical focus indicates fueling operations at this station during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The remediation expenditures documented here — years of groundwater monitoring, in-situ treatment, and well maintenance — arose from releases connected to those pre-1986 operations, and historical CGL carriers who covered the station during that window may still be obligated to recover those 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.
