This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Bay Chemical site in Yakima, Washington is the location of a former chemical facility operation that resulted in significant heavy metal contamination across soil and groundwater. Cleanup activities included excavation of soil containing arsenic, cadmium, chromium, copper, lead, manganese, mercury, and zinc at concentrations exceeding site-specific cleanup levels, followed by construction of an engineered containment area with a cap. A major cleanup action ran from December 2006 through September 2009; remediation construction is now complete, with semiannual groundwater monitoring and annual containment area inspections continuing through at least 2023. 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 heavy metal contamination documented here — arsenic, cadmium, chromium, copper, lead, manganese, mercury, and zinc — reflects the legacy of industrial chemical operations that accumulated over years of facility activity before modern environmental standards were widely enforced. Occurrence-based Commercial General Liability policies issued to Bay Chemical operators prior to 1986 carried no effective pollution exclusion and remain potentially enforceable against releases originating in that pre-regulatory era. The documented remediation expenditures — soil excavation, engineered containment infrastructure, and years of semiannual groundwater monitoring — are the kind of costs that historical carriers may be obligated to recover.
