U.S. EPA issued Information Request Letters to electric utilities that have surface impoundments or similar units that contain coal combustion residuals. EPA’s letters requested information to assist the agency in evaluating the structural integrity of ash ponds at coal-fired utility plants.
EPA will work with other federal and state agencies to identify those ash ponds or similar waste storage units that are unstable and need priority attention.
