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.
This property, associated with a greenhouse building and agricultural operations, was the site of historical chlordane pesticide use that ceased well before the compound was banned nationally in 1988. Chlordane contamination was identified in 1994, with the highest concentrations detected in groundwater near the greenhouse structure. Remedial excavations successfully removed chlordane-contaminated soils, and the site entered the Voluntary Cleanup Program with groundwater monitoring and institutional controls among the evaluated cleanup alternatives. The site has since 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.
Chlordane use at this property predates 1986, placing it squarely within the era when occurrence-based Commercial General Liability policies covered pollution releases without an effective exclusion. The contamination — an organochlorine pesticide migrating through soil into groundwater — is precisely the kind of gradual, long-tail release those policies were designed to address. The remediation costs already incurred here, from soil excavation through extended groundwater investigation, represent expenditures that historical carriers who insured the property's operations during the chlordane-use period may still be obligated to cover.
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.
