This property has a documented history as a gasoline service station going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as a Chevron service station at 1225 Denny Way in Seattle, with underground storage tanks that were removed in 1990. Cleanup under the Voluntary Cleanup Program included remedial excavation, monitoring well replacement, and consistent quarterly groundwater monitoring throughout 1998. Ecology issued a No Further Action determination for the site, updating its Leaking Underground Storage Tank database to reflect closure. 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.
Petroleum hydrocarbon contamination at this site originated from underground storage tanks estimated to have been installed around 1965 — more than two decades before occurrence-based CGL policies ceased reliably covering pollution claims in 1986. The documented remediation expenditures — tank removal, soil excavation, monitoring well replacement, and a full year of quarterly monitoring — were incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during an operational timeline spanning the mid-1960s through 1990 may still be obligated to 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.
