Site description

MidAmerican Energy, a subsidiary of Berkshire Hathaway, and Interstate Power and Light, a subsidiary of Alliant Energy, own and operate Neal North Generating Station near Sioux City, Iowa along the Missouri River in Woodbury County. The station began operating in the 1960s and operated three coal-fired units with a net capacity of 1,080-MW of electricity. Units 1 and 2 were retired in 2016. The station has three coal ash surface impoundments and a coal ash landfill. As of 2011, coal ash disposal occurred in a lined portion of the landfill that was constructed in 2009, and additional disposal areas within the landfill were approved for construction or expansion. Between 2008 and 2010, MidAmerican capped and closed two original disposal areas within the landfill that had received waste since 1978.
