Site description

The Hunter Power Plant is operated and owned by PacifiCorp near Castle Dale, Utah. The plant has three units with the total capacity of 1,372 MW. Hunter began operating in 1978 and disposes of coal ash in a 260-acre CCR Landfill. After dewatering and treatment, flue gas desulfurization (FGD) waste, fly ash and bottom ash are disposed of in the CCR Landfill. There is an estimated 16.8 million cubic yards of coal ash in the landfill as of 2020. You can find the industry-reported data here. For more information on the Hunter Power Plant, see EIP’s 2019 National Coal Ash Report .
