View Rule

The EPA finalized national regulations to provide a comprehensive set of requirements for the safe disposal of coal combustion residuals (CCRs), which are commonly known as coal ash, from coal-fired power plants. The final rule is the culmination of extensive study on the effects of coal ash on the environment and public health. The rule establishes technical requirements for CCR landfills and surface impoundments under subtitle D of the Resource Conservation and Recovery Act (RCRA), the nation's primary law for regulating solid waste. The final rule makes a number of changes from the proposal, including providing greater clarity on technical requirements in response to questions received during the comment period. These regulations address 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 rule sets out recordkeeping and reporting requirements, as well as the requirement for each facility to establish and post specific information to a publicly accessible website. This final rule also supports the responsible recycling of CCRs by distinguishing safe, beneficial use from disposal.
