This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
Two municipal water wells in Waterville, Douglas County were found contaminated with diesel fuel or Fuel Oil No. 2 in 1991, with investigation attributing the source to a closed bulk oil station and two closed gas stations located a few hundred feet north of the wells — consistent with a "Bulk OIL Plant" explicitly depicted on the site diagram. Cleanup in 1992 involved pumping and removing petroleum product from both contaminated wells, which were then permanently abandoned. Municipal well monitoring continued in 1992, 1999, and 2000, with recommendations for annual sampling thereafter. Additional work, including monitoring well installation, remains planned to address carbon tetrachloride contamination identified at the site. 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 petroleum contamination reaching the Waterville municipal wells originated from the closed bulk oil station and nearby gas stations — operations that preceded 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The contamination's off-site, diffuse character — diesel fuel migrating from bulk storage and distribution infrastructure into municipal water supplies — is precisely the type of gradual release those pre-1986 policies were written to cover. Documented remediation costs here include well decontamination, permanent abandonment, years of municipal monitoring, and planned investigation of carbon tetrachloride contamination. Historical carriers who issued CGL policies to the bulk plant or gas station operators during their pre-1986 operating years may remain obligated to fund those costs.
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.
