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 Chevron service station in Seattle before ceasing fuel operations sometime prior to 1993. Groundwater monitoring documented hydrocarbon contamination from the former service station operations, with well sampling and concentration tracking conducted from at least late 1993 through April 1998 under the Voluntary Cleanup Program. A request for a no-further-action designation was submitted in 1998 based on verification monitoring results, and the site has since received No Further Action status. 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 hydrocarbon contamination at this property was explicitly attributed to former service station operations — the type of slow petroleum release from fueling infrastructure that typically develops over years or decades of use. A station already designated "former" by 1993 with contamination significant enough to require five years of groundwater monitoring points to operations well within the pre-1986 window when occurrence-based CGL policies carried no effective pollution exclusion. The remediation costs incurred across that multi-year assessment and cleanup effort are the kind of documented expenditures that historical carriers who insured the station during its operating years may be obligated to cover.
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.
