This property has a documented history as a farm and agricultural operation predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
Gebber Farms, an agricultural operation in Okanogan County, disposed of unrinsed pesticide containers through dumping, burning, and burying at on-site dumps — practices dating to at least the mid-1980s and first reported in a 1989 complaint. The farm used a broad range of agricultural chemicals including paraquat, parathion, phosphamidon, dimethoate, ethion, and captan. In May 1991, the herbicide dinoseb was detected in a drinking water supply well adjacent to the farm's disposal areas, confirming groundwater contamination sourced from the site. An enforcement order followed, three groundwater monitoring wells were installed in June 2002, and the site has since achieved No Further Action status. 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.
Waste disposal practices at Gebber Farms were established prior to 1987, rooted in a farming operation that generated substantial volumes of agricultural chemical waste during a period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The pesticide contamination discovered in groundwater — including dinoseb in an adjacent drinking water well — traces directly to those long-running disposal practices. Historical CGL carriers who covered the farm during its pre-1986 operational window may bear responsibility for the remediation costs incurred to investigate and address that contamination.
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.
