Title: ●Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals From Electric Utilities; Revision of an Alternative Closure Requirement Deadline 
Abstract:

This action proposes to extend one compliance deadline applicable to certain impoundments currently operating pursuant to 40 CFR 257.103(f)(2). Specifically, EPA is proposing to extend the deadline to complete closure of coal combustion residuals (CCR) surface impoundments larger than 40 acres from October 17, 2028, to October 17, 2031. This deadline extension will promote electric grid reliability by accommodating certain coal-fired boilers operating beyond the currently scheduled retirement date.
