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

On May 8, 2024, the Environmental Protection Agency established regulatory requirements, including compliance deadlines, for legacy coal combustion residuals surface impoundments and coal combustion residual management units under the Resource Conservation and Recovery Act. This action extends the existing deadlines for owners and operators of active coal combustion residual facilities or inactive coal combustion residual facilities with a legacy coal combustion residual surface impoundment to comply with the facility evaluation requirements for identifying coal combustion residual management units. This action also extends the existing deadline for owners and operators of coal combustion residual management units to comply with the groundwater monitoring provisions and the remaining provisions for coal combustion residual management units. Finally, EPA is taking final action on several rule amendments that were proposed on January 16, 2025, to correct errors and clarify the coal combustion residual regulations.
