Coal Combustion Residuals (CCR)

Coal Combustion Residuals (CCR) are the byproducts left after burning coal in power plants, including materials like ash, slag, and flue gas desulfurization residues. These residuals contain substances such as arsenic, mercury, and lead, which can be harmful if not managed properly. CCRs are often stored in landfills or ponds, but improper handling can lead to contamination of soil and water resources. Regulations governing CCR aim to ensure safe storage and disposal, minimizing environmental and health risks associated with these residual materials from coal energy production.
