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.
The Gaston Property is a residential site in Seattle where an underground storage tank used for home heating oil released petroleum contamination into the soil. Remediation under the Voluntary Cleanup Program consisted of UST closure and soil remediation directed at that heating oil release. Washington State Ecology has since issued a No Further Action determination, concluding that the contamination no longer poses a threat to human health or the environment. 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.
Heating oil USTs at residential properties were routinely installed decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The remediation costs borne at this property — UST closure and soil excavation — stem directly from a release tied to that pre-1986 operational period. Historical carriers who issued CGL policies to the property's owners during the tank's operational window may retain obligations to fund those cleanup expenditures that have not yet been pursued.
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.
