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 the Utopia Oil service station in Sunnyside, Yakima County, with at least three underground storage tanks — including one that stored leaded gasoline — dispensing fuel for retail sale. Cleanup under the Voluntary Cleanup Program included the removal of all three USTs and excavation of 253.9 tons of petroleum-contaminated soil to a depth of 11 feet, followed by a groundwater monitoring program from 1996 through 2000 that documented declining contaminant levels. The Department of Ecology issued a No Further Action determination in 2001. 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 a leaded-gasoline underground storage tank at this site is direct evidence of fuel operations predating 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The documented remediation costs — tank removals, deep soil excavation, and four years of groundwater monitoring — were incurred to address hydrocarbon releases tied to those long-running pre-1986 operations. Historical carriers who issued CGL policies during that operational window may still be obligated to recover those 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.
