This property has a documented history as a gasoline service station going back to 1975. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Ione Airport property provided fuel sales from underground storage tanks installed in 1975, a date confirmed by an inscription on the concrete dispenser slab discovered during UST decommissioning. Fuel service continued until the early-to-mid 1990s. Domestic well sampling in 2008 detected benzene at 2,200 µg/l — far exceeding the MTCA cleanup level of 5 µg/l — and toluene at 6,200 µg/l, triggering a Site Hazard Assessment. Groundwater monitoring at the airport from 2010 through 2013 showed all BTEX compounds below detection limits, and the site received 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.
Petroleum contamination at this property traces to underground storage tanks installed in 1975, more than a decade before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions. The investigation and remediation costs incurred here — UST decommissioning, site hazard assessment, and years of groundwater monitoring — arose from fuel operations conducted squarely within that pre-1986 policy window. Historical carriers who insured the airport's fuel operations between 1975 and the mid-1980s may still be obligated to cover those documented cleanup 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.
