This property has a documented history as a industrial and manufacturing facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Between 1969 and 1974, approximately 18,000 cubic yards of lime sludge from waste treatment ponds at Occidental Chemical Corporation's (formerly Hooker Chemical Corporation) manufacturing facility were deposited on this BPA property, along with several hundred cubic yards of baghouse dust from an industrial source placed on the eastern portion of the site. Remediation under the Voluntary Cleanup Program included excavation of the impacted soils and sludges and their containment in an on-site engineered landfill with a multi-layer cap. The project is now in the Construction Complete-Performance Monitoring phase, with ongoing groundwater monitoring for VOCs, dissolved gases, and metals, natural attenuation, and continued landfill operation and maintenance — including vegetative cover, drainage swale upkeep, and institutional controls such as restrictive covenants. 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 contamination here traces entirely to industrial waste disposal conducted between 1969 and 1974 — more than a decade before 1986, when occurrence-based Commercial General Liability policies issued to operators like Occidental Chemical Corporation still carried no effective pollution exclusion. Lime sludge and baghouse grit deposited during those years are the documented source of the VOC, metal, and dissolved-gas contamination now subject to long-term groundwater monitoring and permanent institutional controls. Historical carriers who issued CGL policies to the depositing operators during that pre-1986 window may be obligated to recover the documented remediation expenditures: excavation of 18,000 cubic yards of impacted material, construction of an engineered landfill, and ongoing performance monitoring.
