Duke Energy's Buck Steam Station began operating in 1926 in Spencer, North Carolina along the Yadkin River. At its peak, it had four coal-fired units that could generate 256 megawatts (MW). Duke Energy retired all units at the steam station during 2011-2013. The site is now home to a new 620 (MW) natural gas-fired power plant. The Environmental Protection Agency designated three of the ash ponds on-site as having significant-hazard dams.
The State of North Carolina entered into a consent decree with Duke Energy in August 2013 regarding seeps and other un-permitted discharges to groundwater at the site. As of June 2014, nearby residents and environmental groups expressed concerns about residential wells contaminated with chromium.
Three units near the station, Ash Basin 1, 2 and 3, are regulated under the CCR rule. You can find the industry-reported data here. For more information on the Buck Steam Station, see EIP’s 2019 National Coal Ash Report.
