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 Former Exxon Station 7-2518, a gasoline service station at 2510 South 320th Street in Federal Way. Gasoline hydrocarbons, heavy oil hydrocarbons, and lead were released into the soil and groundwater — contaminants consistent with leaded-gasoline-era fueling operations. An Independent Remedial Action was carried out under the Voluntary Cleanup Program, including quarterly groundwater monitoring conducted by multiple consultants over a multi-year period. Ecology's Toxics Cleanup Program issued a No Further Action determination in 2002. 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 presence of lead in soil and groundwater at this site is a signature of leaded gasoline dispensing, which places the contaminating operations squarely before 1986 — the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — independent cleanup action, years of quarterly groundwater monitoring by successive consultants — were incurred to address releases that originated during that insured window. Historical carriers who covered the station's operators during the leaded-gasoline era 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.
