Site description

Leland Olds Station is a 669-MW coal-fired power generating station owned by Basin Electric Power Cooperative. The plant is located near Stanton, North Dakota and began commercial operations in 1966. The station disposes of fly ash, bottom ash, and FGD waste at the Glenharold CCR landfill located 3 miles southwest of the facility, which encompasses 148.2 acres within the former Glenharold Mine. Three municipal drinking water wells are located within 5 miles of Leland Olds Station. The Environmental Protection Agency identified Leland Olds as a potential damage case in 2007 and classified all three ash ponds as significant-hazard dams in 2011. You can find the industry-reported data here. For more information on the Leland Olds Station, see EIP’s 2019 National Coal Ash Report .
