This property has a documented history as a property with a heating oil tank going back to 1941. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This residential property was built in approximately 1941, with an above-ground storage tank and underground fuel lines serving an oil-burning heating system installed as part of the original construction. A release of petroleum hydrocarbons from the heating fuel system contaminated both soil and groundwater at the site. Cleanup under the Voluntary Cleanup Program included excavation and removal of 4,470 gallons of petroleum-impacted groundwater, with TPH as diesel detected at concentrations exceeding MTCA Method A cleanup levels. Ecology issued a No Further Action determination in June 2003, confirming the release no longer poses 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 heating oil system at this property dates to 1941 — more than four decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions in 1986. The petroleum release from that system required remediation of both soil and groundwater, costs incurred to address contamination originating squarely within the pre-1986 policy window. Historical carriers who covered this property during the decades the oil-burning system was in operation may be obligated to reimburse those documented cleanup expenditures.
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.
