This legislative proposal aims to invalidate a specific final rule promulgated by the Environmental Protection Agency (EPA) on May 9, 2024. The rule addresses greenhouse gas emissions from various types of electric generating units across the United States. Specifically, it establishes New Source Performance Standards for new, modified, and reconstructed fossil fuel-fired units, and sets Emission Guidelines for existing fossil fuel-fired electric generating units. Additionally, the EPA rule that this bill targets includes the repeal of the Affordable Clean Energy Rule . If enacted, this bill would ensure that the EPA's comprehensive rule regarding power plant emissions would have no legal force or effect.
