This Chevron service station at 25 NW Gilman Blvd in Issaquah was listed in Washington's Leaking Underground Storage Tank database after a release of gasoline from underground storage tanks contaminated both soil and groundwater. Remediation was completed by 2000 under the Voluntary Cleanup Program, and the Department of Ecology issued a No Further Action determination in February 2001. Confirmed groundwater contamination included both petroleum compounds and metals. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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 underground storage tanks responsible for the gasoline release at this station are consistent with infrastructure installed during the pre-1986 era, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented contamination — gasoline in soil and groundwater, metals confirmed in groundwater — and the remediation expenditures required to reach No Further Action status represent costs potentially recoverable from historical carriers whose CGL policies were in force when the release originated.
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.
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.
