This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property served as the Washington State Department of Transportation's Mount Vernon Area 2 Maintenance Headquarters, where underground storage tanks holding gasoline, diesel, and waste oil supported fleet fueling operations. In 1990, all three USTs were removed and petroleum-contaminated soil was overexcavated; groundwater encountered during excavation was managed as part of the same response. From the release notification in November 1990 through the no further action determination, the site remained under active regulatory oversight for 22 years under Washington's Standard 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 UST releases at this facility trace to tanks that were in service well before 1986 — the period when occurrence-based Commercial General Liability policies had no effective pollution exclusion and routinely covered gradual contamination from fleet fueling operations. A government maintenance headquarters of this type would have carried institutional insurance during those decades of pre-1986 operations. The documented remediation costs — tank removal, soil excavation, groundwater management, and more than two decades of regulatory oversight — represent expenditures that historical carriers writing coverage during that operational window may remain obligated to recover.
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.
