Better Solutions for Coal Ash Containment Following EPA Ruling

Coal ash containment has been largely unregulated at the federal level, In April 2015, the EPA published its national regulations on the safe disposal of coal combustion residuals, or coal ash. These new requirements have forced utility companies to develop new coal ash containment systems in order to comply with the new regulations.

The rules surrounding coal ash containment establish technical requirements for coal ash landfills and surface impoundments under subtitle D of the Resource Conservation and Recovery Act, which is America’s primary law for regulating solid waste.

Hazards of Coal Ash Disposal
