Comment submitted by National Mining Association (NMA)

Summary: The National Mining Association (NMA) supports the proposed rule regarding unmanaged combustion residual leachate (CRL) because it provides regulatory clarity and avoids infeasible zero-liquid discharge (ZLD) standards. However, the NMA also urges the EPA to repeal the ZLD standards for other wastewater streams and remove retirement subcategories from the 2024 ELG Rule, arguing they are technologically unachievable and incentivize the closure of coal-fired power plants.
