"This month, the Environmental Protection Agency will propose standards that will establish stricter pollution limits for gas-fired power plants than coal-fired power plants, according to individuals who were briefed on the matter but asked not to be identified because the rule was not public yet."
"The revised rule, which would impose greenhouse gas limits on power plants for the first time, will still require utilities to install costly carbon controls on coal plants.
The agency initially proposed that any new power plant emit no more than 1,000 pounds of carbon dioxide per megawatt hour of electricity produced but decided to overhaul that rule this spring out of concern that it would face a stiff legal challenge."
