Rule may set separate emissions limits for coal-, gas-fired plants

The U.S. Environmental Protection Agency is reportedly going to propose a revised rule that would set different emissions limits for new coal- and natural gas-fired power plants, according to the Wall Street Journal.

The article said the revised rule would propose an emissions limit of 1,100 pounds of carbon dioxide per megawatt hour for coal plants and 1,000 pounds per MWh for large gas-fired plants. The previous version had a 1,000 pound per MWh limit for both types of plants.

Newer coal-fired power plants would also have to be equipped with emissions controls or carbon capture and storage technology, which some say could effectively ban new plants. The rule must be finalized by Sept. 20, though some expect there will be lawsuits, the article said.

EPA has until June 2014 to finalize standards for existing power plants, the report said.
