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 residential Seattle property contained an underground storage tank used for heating oil that the property owner had removed in early 2005 after noticing oil loss. Remediation under the Voluntary Cleanup Program proceeded in two excavation phases — September–October 2005 and March 2006 — removing a total of 904 tons of petroleum-contaminated soil, with excavated areas backfilled with clean material. Cleanup activities ran from 2005 through 2007, and the site has since received a No Further Action determination. 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 petroleum hydrocarbon contamination here traces to a residential heating oil UST that, by the documented chronology, was in operation prior to 1986 — when occurrence-based CGL policies were still standard and lacked effective pollution exclusions. The two-phase excavation that removed 904 tons of contaminated soil represents a substantial documented remediation expenditure tied directly to that pre-1986 tank operation. Historical carriers who issued coverage to the property during that operational window may bear an obligation to fund or recover those cleanup 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.
