This property has a documented history as a farm and agricultural operation going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This Pacific County property operated as a cattle ranch under the Nelson family from the 1940s into the 1970s, with a concrete cattle dip tank used to treat livestock for external parasites using chemical pesticide additives. Contamination from those decades of dipping operations was documented through site surveys in 1995 and 1996, prompting a multi-year cleanup under the Standard Cleanup Program that included soil sampling and investigation, an interim removal action targeting soil contaminants, and a final action addressing groundwater contamination. The site has since reached 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.
Pesticide contamination at this property originates directly from cattle dipping operations that began in the 1940s — more than three decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The remediation costs incurred here — investigation, soil excavation, and groundwater treatment — were driven by releases tied to those pre-1986 agricultural operations. Historical carriers who issued CGL policies to the Nelson family or property operators during that window may still be obligated to recover 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.
