Coal Combustion Residues (CCRs)

Coal combustion residues (CCRs), more commonly known as coal ash, are a byproduct of the combustion of coal at power plants. The ash is then disposed in liquid form at large surface impoundments and in solid form at landfills. Ongoing research evaluates the safest disposal methods as well as potential benefits and uses for CCRs.
