This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The BPA Elma Substation is a federally owned and operated power facility under the Bonneville Power Administration. Approximately 15 buried drums were discovered during a substation expansion, prompting a response from September 2013 through April 2014 that involved removal of all 15 drums and excavation of roughly 600 cubic yards and 1,700 tons of diesel-contaminated soil from an area approximately 90 by 65 by 25 feet deep. Diesel contamination remains in the subsurface, groundwater monitoring wells are planned for installation, and the site requires continued remediation. 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 buried drums at this site were placed in the ground prior to 1984, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The cleanup conducted to date has removed the drums and the most heavily impacted soil, but the diesel plume persists and the costs of the next phase — groundwater monitoring installation, continued investigation, and further remediation — remain ahead. Historical carriers who issued CGL policies to BPA or its predecessors during the pre-1986 operational window may be obligated to fund those upcoming cleanup expenditures.
