Eagle Valley was a 302 MW facility owned and operated by Indianapolis Power & Light in Martinsville, Indiana. All four units at Eagle Valley were retired in April 2016. Eagle Valley held what the EPA deemed a 'high hazard pond' from 2011 data based on National Inventory of Dams (NID) criteria. This was one of five ponds present at the facility. Combined, these coal ash ponds covered 80 acres of land and contained 2.9 million cubic yards of coal ash and waste materials. These ponds were the source of two spills into the White River in 2007 and 2008, resulting in the release of 60 million gallons of coal ash sludge.
