This property has a documented history as a gasoline service station going back to 1981. 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 at least three underground storage tanks, an aboveground storage tank, and a pump island used for fuel dispensing. Cleanup under the Voluntary Cleanup Program included UST decommissioning and likely removal, soil excavation, confirmation soil sampling, and quarterly groundwater monitoring from 2006 through 2007 to address benzene contamination. The site has 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 and benzene contamination at this site originated from underground storage tanks estimated to have been installed around 1981 — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank decommissioning, soil excavation, multi-year groundwater monitoring — were incurred to address releases from those pre-1986 operations. Historical carriers who issued CGL policies during the tanks' operational window may still be obligated to cover 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.
