Site description

Basin Electric Power Cooperative’s Antelope Valley Station opened in 1984 and is located eight miles northwest of Beulah, North Dakota. The Antelope Valley Station consists of two coal-fired units that generate approximately 900 MW. The station disposes of fly ash, bottom ash, and FGD waste at a landfill located northeast of the facility. The landfill is regulated under the CCR rule. Antelope Valley Station also has a Spray Dryer Ash Make-Up Water Pond and a Decant Pond on-site, but neither of them are regulated under the CCR rule because of their usage for plant process water storage and management. You can find the industry-reported data here. For more information on the Antelope Valley Station, see EIP’s 2019 National Coal Ash Report.
