Newly revised and yet-unreleased carbon dioxide pollution rules devised by the U.S. Environmental Protection Agency (EPA) could possibly set different caps for coal-fired power plants and natural gas-fired power plants, according to reports.
The revised rule would propose a limit of 1,100 pounds of carbon dioxide per MWh of coal power and 1,000 pounds per MWh of gas power. Previous incarnations of the rule limited both power generation sources to 1,000 pounds per MWh.
The public comment period for the EPA’s carbon dioxide rule ends September 20, after which it will be released. The EPA has until June 2014 to finalize standards for existing power plants.
Newer coal-fired power plants would also have to be equipped with emissions controls or carbon capture and storage technology, which some companies and industry groups have said would effectively ban the construction of new coal plants.
