WASHINGTON — The Environmental Protection Agency will issue the first limits on greenhouse-gas emissions from new power plants as early as today, according to several people briefed on the proposal. The move could end the construction of new conventional coal-fired facilities in the United States.
The proposed rule — years in the making and approved by the White House after months of review — will require any new power plant to emit no more than 1,000 pounds of carbon dioxide per megawatt of electricity produced. The average U.S. natural-gas plant, which emits 800 to 850 pounds of CO2 per megawatt, meets that standard; coal plants emit an average of 1,768 pounds of carbon dioxide per megawatt.
Industry officials and environmentalists said in interviews that the rule, which comes on the heels of tough new requirements that the Obama administration imposed on mercury emissions and cross-state pollution from utilities within the past year, dooms any proposal to build a new coal-fired plant that does not have costly carbon controls.
“This standard effectively bans new coal plants,” said Joseph Stanko, who heads government relations at the law firm Hunton and Williams and represents several utility companies. “So I don’t see how that is an ‘all-of-the-above’ energy policy.”
The rule provides an exception for coal plants that are already permitted and beginning construction within a year. There are about 20 coal plants now pursuing permits; two of them are federally subsidized and would meet the new standard with advanced pollution controls.
The EPA rule, called the New Source Performance Standard, will be subject to public comment for at least a month before being finalized.
