The Final Rule also imposes requirements on an additional, new category of CCR units, known as CCR management units, or CCRMUs. Regulated legacy CCR surface impoundments will need to comply with the requirements in Subpart D, as articulated in the Final Rule, beginning as early as six months after the date of publication of the Final Rule in the Federal Register and CCRMUs will need to comply with specified requirements beginning 21 months after publication.

EPA, in which the Court vacated and remanded the provision of the 2015 CCR Rule that exempted inactive impoundments at inactive facilities from regulation. EPA is also expanding the CCR Rule to address CCRMUs due to the associated risks from the direct placement of CCR on the land; according to information obtained from EPA since 2015, these previously unregulated units are contaminating groundwater and pose risks similar to the risks associated with currently regulated activities. In the last year, EPA has focused on CCR Rule enforcement, adding “protecting communities from coal ash contamination” as one of EPA’s six National Enforcement and Compliance Initiatives for fiscal years 2024 through 2027. …
