Dynegy's Zimmer Power Station is a 1,425 MW coal-fired power plant located on the Ohio River near Moscow, in Clermont County, Ohio. Four coal ash disposal areas at the site are regulated by the federal coal ash rule: a lined 4-acre coal pile runoff pond, a lined gypsum storage pond, a landfill, and another 9-acre pond called D Basin. The coal pile runoff pond and D basin are considered significant hazard dams, meaning that failure or mis-operation could result in off-site environmental damage. The coal pile runoff pond was constructed in the 1980s and has a storage capaicity of 17 acre-feet. D basin was constructed after 2002 and has a capacity of 4 acre-feet.
