This EIS was to analyze WAPA's proposed action for the construction and operation of the proposed NextGen Energy Facility (Project) in South Dakota. Basin Electric Power Cooperative (BEPC) had proposed to design construct, operate, and maintain a 500- to 700-megawatt base load, coal-fired generation facility near Selby, Walworth County, South Dakota, and interconnect it with Western's transmission system. WAPA cancelled this EIS because BEPC notified WAPA that is was suspending further action on its proposed project.
