This joint resolution disapproves an Environmental Protection Agency rule issued in May 2024 that governs how electric utilities must dispose of coal combustion residuals, which are the waste byproducts left over from burning coal for electricity. The resolution uses the Congressional Review Act, a law that allows Congress to overturn federal agency regulations. If passed, the EPA rule would be nullified and have no legal effect, meaning electric utilities would not be required to follow the disposal standards the EPA had established. The resolution affects electric power companies and the EPA's regulatory authority over coal ash waste management, though no specific funding amounts or implementation timelines are mentioned in the text.
