Snapshot

Allen Steam Station has 14 groundwater monitoring wells, 12 of which have been polluted above federal advisory levels based on samples collected between February 16, 2011 and September 25, 2017. Groundwater at this site contains unsafe levels of arsenic, boron, molybdenum, fluoride, lead, manganese and barium.

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 MW. The Environmental Protection Agency classified the active ash pond onsite as having a significant-hazard dam. In 2015, Duke Energy agreed to close three units of the plant by the end of 2024. There are three areas regulated under the CCR rule: Active Ash Basin, Retired Ash Basin and Retired Ash Basin Landfill. You can find the industry-reported data here.
