The US Environmental Protection Agency (EPA) has proposed Clean Air Act standards to reduce CO 2 emissions from fossil-fuel fired power plants (electric utility generating units, EGUs). The proposed rulemaking establishes separate standards for natural gas and coal plants. 1,100 lb CO 2 /MWh-gross over a 12-operating month period; or.
