Snapshot

Montour Steam Station has 19 groundwater monitoring wells, 18 of which have been polluted above federal advisory levels based on samples collected between May 16, 2016 and October 10, 2017. Groundwater at this site contains unsafe levels of lithium, sulfate, cobalt, barium, radium, antimony, beryllium and cadmium.

Site description

Talen Energy Company’s Montour Power Plant is located in Montour County, PA, along the banks of a tributary to the Susquehanna River. The Montour Plant began operation in 1971 and is now capable of producing 1,515 MW from its two coal-fired units. As of 2017, Talen Energy Company has been researching into the conversion for one of its two coal-fired units to natural gas. The Montour Plant disposes of wastewater treatment sludge, fly ash, mill rejects, and sump sludges into Disposal Area 3, a residual waste landfill just south of the main generation station. There is also a 155-acre unlined dike disposal impoundment, Basin 1, where fly ash, bottom ash, and mill rejects are disposed. Both Area 3 and Basin 1 are regulated under the CCR rule. You can find the industry-reported data here. For more information on the adverse effects of coal-ash groundwater pollution, and information on Montour Plant emissions, see EIP’s 2019 National Coal Ash Report.
