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 was the site of a gasoline release from leaking underground storage tanks, with total petroleum hydrocarbons (TPH) detected in both soil and groundwater. Remedial excavation and monitoring were conducted between 1993 and 1996 under Ecology's Standard Cleanup program, ultimately leading to a No Further Action determination after the agency concluded the release no longer posed a threat. 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.
The petroleum contamination at this site originated from underground storage tanks that were installed and operated during the era when occurrence-based Commercial General Liability policies were the industry standard, carrying no effective pollution exclusion. The remediation expenditures incurred across three years of excavation and monitoring to address that gasoline release are the type of documented cleanup costs that historical CGL carriers 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.
