Coal Combustion Residuals Regulation (January 22, 2018) – Coal combustion residuals, commonly known as coal ash, are created when coal is burned by power plants to produce electricity. Coal ash is reportedly one of the largest types of industrial waste generated in the United States. This regulation for the disposal of coal combustion residuals from electric utilities became effective on October 4, 2016 and provides a comprehensive set of requirements for the safe disposal of CCRs, commonly known as coal ash, from coal-fired power plants. The regulation establishes technical requirements for CCR landfills and surface impoundments under Subtitle D of RCRA and addresses the risks from coal ash disposal — leaking of contaminants into ground water, blowing of contaminants into the air as dust, and the catastrophic failure of coal ash surface impoundments. Additionally, the requirements for recordkeeping and reporting as well as the requirement for each facility to establish and post specific information to a publicly-accessible website are established. This regulation also supports the responsible recycling of CCRs by distinguishing safe, beneficial use from disposal.
