This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as a gasoline service station, with an underground storage tank, associated product lines, and dispensers — all reportedly removed before Washington State UST regulations took effect in 1990. An Independent Remedial Action Plan executed in 1997 involved overexcavation of petroleum-contaminated soil, which was landfarmed on-site; groundwater contamination was addressed through natural attenuation, with successful results documented in 1998. A No Further Action determination was issued in 2012, closing a remediation record that spanned more than a decade. 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 gasoline release here is tied to a storage tank that predates Washington's 1990 UST regulations and, by reasonable inference, was installed and in operation well before 1986 — the dividing line for occurrence-based Commercial General Liability coverage with no effective pollution exclusion. That pre-1986 operational window is precisely when the contamination originated, making historical CGL carriers potentially obligated to the costs already incurred: soil excavation and landfarming, groundwater monitoring, and the multi-year regulatory process that concluded with the 2012 NFA.
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.
