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.
The Whistle Stop Chevron property in Tenino operated as a gasoline service station with underground storage tanks dispensing petroleum products. Cleanup under the Voluntary Cleanup Program included UST decommissioning, soil excavation, on-site land farming through aeration and windrowing, and groundwater treatment using aeration and activated carbon filtration completed in May 2008. The site has 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.
Petroleum hydrocarbon contamination at this property resulted from underground storage tanks whose installation and long-term operation are consistent with pre-1986 fueling activities — the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank decommissioning, soil excavation and land farming, groundwater treatment — represent cleanup costs that historical carriers who issued CGL policies during the tanks' operational window may still be obligated to cover.
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.
