FirstEnergy Generation Corporation will pay an $800,000 civil penalty and close an impoundment where it disposes of coal ash from the Bruce Mansfield power plant in western Pennsylvania under a July 27 settlement with the Pennsylvania Department of Environmental Protection in the U.S. District Court for the Western District of Pennsylvania. At issue was the potential for groundwater and surface water contamination as a result of leaks from Little Blue Run, an unlined 1,700-acre coal ash impoundment in Pennsylvania and West Virginia.
