Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals From Electric Utilities; CCR Management Unit Deadline Extension Rule

The Environmental Protection Agency (EPA or the Agency) is proposing to modify compliance deadlines for select provisions published in the Federal Register on May 8, 2024. This May 8, 2024 rule (Legacy Final Rule) established regulatory requirements for legacy coal combustion residuals (CCR) surface impoundments and CCR management units (CCRMU) under the Resource Conservation and Recovery Act (RCRA). This proposal seeks comment on issues discussed in the direct final rule published in this Federal Register to establish an additional option for owners or operators of active CCR facilities or inactive CCR facilities with a legacy CCR surface impoundment to comply with the Facility Evaluation Report (FER) Part 1 and to extend compliance deadlines for the remaining CCRMU provisions published in the Legacy Final Rule. EPA is also soliciting comment on extending the deadline to prepare both FER Part 1 and Part 2 by 12 months.
