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 at 3101 First Avenue, Seattle operated as a gas station, with underground storage tanks (USTs) and associated piping and containment systems on site. A March 2002 report documenting UST and piping-and-containment-system removal and confirmation sampling concluded that the release of TPH-Oil, TPH-Diesel, and Lead into the soil no longer poses a threat to human health or the environment. The site reached No Further Action status under the Voluntary Cleanup Program. 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 presence of Lead alongside TPH-Oil and TPH-Diesel in the soil is characteristic of leaded-gasoline operations that predate 1986, the year leaded fuel was largely phased out and occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. UST operations during that pre-1986 window would have been covered by policies that remain potentially enforceable today. The documented remediation at this site — tank removal, piping excavation, and confirmation sampling — represents costs that historical carriers whose policies were in force during those earlier decades of operation may be obligated to fund.
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.
