EPA proposes to extend the compliance deadline for owners and operators of coal combustion residuals (CCR) surface impoundments to cease operation of their coal-fired boilers and complete closure of their CCR surface impoundments larger than 40 acres by three years, from October 17, 2028, to October 17, 2031. This change responds to recent findings from the Department of Energy indicating that retirement of coal-fired power generating assets could cause electric grid reliability risks.
EPA will hold a virtual public hearing on this proposal on Jan. 6, 2026.
