12:30 p.m. -- The Partnership for a Better Energy Future, an industry coalition that includes more than 150 groups like the American Petroleum Institute and the Chamber of Commerce, have submitted a letter to EPA asking that the agency "go back to the drawing board" on its rule for existing power plants. The groups write that the rule "will be disruptive to and is fundamentally incompatible with numerous practical and technical aspects of America's electricity system." The groups also request an extended comment period and additional public hearings to present technical analyses. -- Jason Plautz
