This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This residential property in Seattle's Sand Point neighborhood was the site of a leaking underground heating oil storage tank that released petroleum hydrocarbons into both soil and groundwater. The contamination was enrolled in Washington's Voluntary Cleanup Program, and remediation was carried out to address the petroleum release. Ecology issued a No Further Action determination in October 2000, confirming that cleanup standards had been met. 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.
Residential heating oil tanks in this Seattle neighborhood were typically installed with the original homes, built during the 1940s through 1960s — well before 1986, when occurrence-based Commercial General Liability policies were still the prevailing standard and carried no effective pollution exclusion. The petroleum release from this underground storage tank and the resulting remediation expenditures represent the kind of long-tail environmental liability those mid-century policies were designed to cover. Historical carriers whose policies were in force during the tank's pre-1986 operational decades may still be obligated to reimburse the cleanup costs incurred at this property.
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.
