Site descriptionDTE Energy’s Monroe Power Plant is a four-unit coal-fired power plant with a net capacity of 3,280-MW and has been online since 1971. The plant is located on a 200-acre peninsula that juts into Lake Erie, Michigan in Monroe. DTE has planned to retire the facility by 2040. There are two coal ash disposal-related facilities at this site. The first is an 18,500-acre-foot Fly Ash Basin located west of the plant. It was classified as a "significant hazard" dam by the Environmental Protection Agency, though it is regulated as a landfill under Michigan law. The second disposal facility is the Inactive Bottom Ash Basin, which is classified as a low-hazard dam. The Fly Ash Basin is regulated under the CCR rule.
