Site description

Wood River Power Station was a 500-MW plant owned and operated by Dynegy near Alton, Illinois near the Mississippi River in Madison County. The plant was first built in 1954 and had two coal-fired units at its peak. It was retired in June 2016. In 2005, Wood River was involved in a settlement between the EPA and Dynegy regarding violations of New Source Review Provisions of the Clean Air Act. The plant disposed of ash in two disposal areas regulated by the CCR rule: Primary East Ash Pond and West Ash Ponds. Wood River Power Station was listed among the U.S. EPA's proven damage cases, indicating that it has polluted groundwater or surface water at levels which threaten human health and the environment.
