October 17, 2024--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--The U.S. Supreme Court on Wednesday denied a request from two dozen Republican-led states, utilities and energy interests to intervene in a significant Clean Air Act case that currently is being litigated in lower federal courts. This case involves the Biden administration's finalized rule sharply limiting future carbon dioxide (CO2) emissions from existing coal-fired generators and future gas-fired generators. For more on that final rule from the U.S. Environmental Protection Agency (EPA) (Washington, D.C.), see April 26, 2024, article - EPA Issues Rules That Could Reshape Electric Generation.
