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 Mercer Island residential property — the Pelton Residence — experienced a release of heating oil range petroleum hydrocarbons from an underground storage tank, contaminating both soil and shallow groundwater. Independent remedial actions, including a Phase III remediation project and groundwater sampling, were conducted between 1997 and 1999 under Washington's Voluntary Cleanup Program. Ecology issued a No Further Action determination in December 1999, concluding that residual 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.
Residential heating oil tanks like the one at this property are infrastructure installed and operated over decades — typically well before 1986, when occurrence-based CGL policies still carried no effective pollution exclusion. The documented release and the multi-year Phase III remediation effort it required represent real cleanup expenditures tied directly to that tank's operational history. Historical carriers who issued liability policies during the years the tank was in service may have an obligation to respond to those remediation 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.
