This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Oberto Kent Plant is a light industrial facility occupied by the Oberto Sausage Company, with the on-site building constructed between 1966 and 1999, placing the earliest operations in the pre-1986 era. The site operates a 4,000-gallon diesel underground storage tank connected to a fuel dispenser on the east side of the property. In-situ groundwater remediation — using an injected blend of nitrate and sulfate as electron acceptors — was initiated in June 2020 and remains ongoing, with four consecutive monitoring events now recording contaminant levels below cleanup standards. 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.
Industrial operations at this property began no later than the late 1960s, well within the period when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington State. The groundwater impacts now being addressed through the 2020 bioremediation program are tied to decades of industrial activity and an on-site diesel storage system whose origins predate 1986. Historical carriers that issued CGL policies to the Oberto operation during that pre-1986 window may remain obligated to fund the continuing remediation expenditures as the site progresses toward closure.
