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.
Ferndale High School operated a 1,000-gallon underground gasoline storage tank in its bus yard to fuel school district vehicles. In February 1994, the tank was found leaking; inspection revealed corrosion holes running throughout the tank ends and sides, top to bottom. Cleanup included pumping the tank contents, CO2 purging, removal of the UST, excavation and on-site aerated treatment of approximately 60 cubic yards of contaminated soil, fan aeration of the excavation pit, backfilling, and subsequent groundwater and soil monitoring — all of which indicated successful remediation and supported 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 severe corrosion documented at the time of tank removal — holes distributed from end to end across the tank walls — points to an aging tank that had been in service for many years before the 1994 discovery, well within the era when occurrence-based Commercial General Liability policies provided no effective pollution exclusion. A tank exhibiting that degree of deterioration when removed in 1994 is consistent with installation and continuous operation prior to 1986, meaning petroleum releases into the bus yard soil and groundwater were likely occurring throughout the period those historical policies were in force. The Ferndale School District's CGL carriers from that pre-1986 window may remain obligated to contribute to the documented remediation expenditures.
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.
