The U.S. Environmental Protection Agency (EPA) has proposed extending the closure deadline for certain coal combustion residuals (CCR) surface impoundments. This proposal would move the deadline from October 17, 2028, to October 17, 2031, allowing a select group of owners and operators more time to cease operations of coal-fired boilers and close unlined CCR surface impoundments larger than 40 acres.
This extension aims to support electric grid reliability by permitting some baseload coal-fired power producers to operate for an additional three years beyond the original deadline. "President Trump understands that maintaining baseload capacity is critical to providing affordable and reliable energy for all Americans," said Steven Cook, Principal Deputy Assistant Administrator for the Office of Land and Emergency Management. He added that the proposal offers flexibility for coal-fired power plants to meet requirements while continuing to contribute to national prosperity and energy independence.
The extension targets CCR surface impoundments operating under alternative closure provisions for permanent cessation by a specified date. The EPA is inviting public comments on this proposal until January 7, 2026, with a virtual public hearing scheduled for January 6, 2026. More details can be found on the CCR rulemaking webpage.
On March 12, 2025, the EPA committed to rapid action on CCR management. Since then, it has approved North Dakota's CCR program and proposed approval for Wyoming's program. The agency continues collaborating with states on effective CCR disposal operations in surface impoundments and landfills.
