EPA’s current proposal to retract well-justified regulation of toxic coal-ash ponds and landfill disposal of coal-ash residue, if adopted, would increase grave hazards to public health and the environment. Such backsliding would flagrantly contradict the very purpose of the U.S. Environmental Protection Agency. Proponents of the roll-backs claim they would save up to $100 million a year in compliance costs for the industries that generate coal-ash toxins in profit-making operations.
