MidAmerican Energy, a subsidiary of Berkshire Hathaway, owns and operates Neal North Generating Station near Sioux City, Iowa along the Missouri River. The 1,046 MW power station began operating in the 1960s. The station has three surface impoundments that contain coal ash 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.
As a result of a settlement with environmental groups, MidAmerican plans to stop burning coal in two of the Station's three boilers by spring 2016.
George Neal North is listed among the U.S. Environmental Protection Agency's potential damage cases, indicating that it has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
