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 service station with underground storage tanks at what is now the Hwy 9 Shopping Center in Snohomish County. A gasoline release from the USTs contaminated soil and groundwater, prompting independent remedial actions and over a decade of groundwater monitoring and sampling from 1991 through 2002 under the Voluntary Cleanup Program. Ecology determined that the release no longer poses a threat, and the site received a No Further Action designation. 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 contamination at this property originated from leaking underground storage tanks associated with service station operations that predate 1986 — the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than a decade of remedial investigation, groundwater monitoring, and sampling was required to resolve the release and secure regulatory closure. Historical carriers who issued CGL policies during the station's pre-1986 operational window may still be obligated to cover the cleanup costs incurred to address contamination from that period.
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.
