This joint resolution would reject an Environmental Protection Agency rule that updates emission standards for hazardous air pollutants from coal- and oil-fired power plants. The EPA rule, published in May 2024, requires these electric utility facilities to review and potentially reduce their emissions of dangerous pollutants like mercury and other toxins. If passed, this resolution would nullify the EPA rule entirely, preventing it from taking effect. The bill uses the Congressional Review Act, a process that allows Congress to disapprove federal regulations, and affects power generation companies that operate coal and oil-fired facilities across the country. No specific funding or implementation timeline is addressed in the resolution itself.
