Allen Steam Station has 13 groundwater monitoring wells, 4 of which have been polluted above federal advisory levels based on samples collected between March 01, 2011 and March 02, 2015. Groundwater at this site contains unsafe levels of nickel and manganese.Site description
Duke Energy's Allen Steam Plant opened in 1957 and is located on the banks of the Catawba River in Gaston County, North Carolina. It has five coal-fired generating units that are capable of producing 1,140 megawatts (MW) of electricity. The Environmental Protection Agency (EPA) classified the active ash pond onsite as having a significant-hazard dam.
In its 2007 Damage Case Assessment, the EPA found that there were documented exceedances of non-health based standards for manganese and iron in wells downstream from the facility based on historic data. In August 2013, the State of North Carolina entered into a consent decree regarding seeps and other un-permitted discharges to groundwater. Concerned that the State would not require Duke Energy to implement any meaningful remedies, the Catawba Riverkeeper sought (and was granted) the opportunity to intervene in the ongoing case.
