On April 17, 2025, the U.S. Environmental Protection Agency (EPA) announced it will extend the compliance deadlines for coal combustion residual (CCR) management unit (CCRMU) requirements. This action will allow facilities to submit both sections of the Facility Evaluation Report simultaneously, provided that both reports are turned in no later than February 8, 2027.
EPA is also extending the groundwater monitoring requirements for owners or operators of coal combustion residual management units until August 8, 2029. Because the Facility Evaluation Report and groundwater monitoring requirements are necessary for compliance with other CCRMU requirements, EPA is aligning these remaining CCRMU compliance deadlines.
EPA has proposed to approve North Dakota’s CCR program application, which would allow the state to manage coal ash disposal in surface impoundments and landfills. EPA is also working with Wyoming and other states as they seek to manage their CCR programs without federal oversight.
EPA is accepting comments for 30 days after publication in the Federal Register. Unless EPA receives adverse comments, this final rule will be effective six months after publication in the Federal Register.
