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 Woodinville commercial property is associated with a leaking underground storage tank that released total petroleum hydrocarbons into the soil. Independent remedial action and cleanup activities were conducted to address the contamination, and in 1998 the Washington Department of Ecology issued a No Further Action determination under the Voluntary Cleanup Program, confirming that the former 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 underground storage tank at this property had already leaked, been remediated, and received regulatory closure by 1998 — placing the tank's installation and active use squarely in the decades before that date, when the property's commercial operations would have been insured under occurrence-based CGL policies. The remedial action and cleanup costs incurred to bring this site to No Further Action status are expenditures that historical carriers who covered this property during the tank's operating life may still be obligated to reimburse.
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.
