CNN — The Environmental Protection Agency is proposing new rules aimed at limiting the amount of carbon pollution coming from new power plants.
The standards, which would set separate limits for natural gas and coal power plants, are being called the first uniform national limits for new plants.
"Power plants are the single largest sources of carbon pollution," EPA Administrator Gina McCarthy said in remarks prepared for delivery at the National Press Club in Washington. "New power plants can minimize their carbon emissions by taking advantage of modern technologies. These technologies offer them a clear path forward, today and in the long-term."
New coal power plants and small natural gas plants would be limited to 1,100 pounds of C02 emissions per megawatt-hour. Larger natural gas plants would be limited to one thousand pounds a megawatt-hour.
These restrictions are slightly looser than a set first proposed in 2012. McCarthy said the new proposal factors in public feedback from public comments received last year.
Existing power plants are exempt from the proposed carbon regulation, but McCarthy said regulations on those plants will be proposed in June.
Sen. Joe Manchin, a Democrat who represents coal-rich West Virginia, criticized the administration as trying to hold the coal industry to "impossible standards"
"Never before has the federal government forced an industry to do something that is technologically impossible. Forcing coal to meet the same emissions standards as gas when experts know that the required technology is not operational on a commercial scale makes absolutely no sense and will have devastating impacts to the coal industry and our economy," he said in a written statement.
McCarthy said the EPA has a history of pollution standards driving technological development.
"The old rules may say we can't protect our environment and promote economic growth at the same time, but in America, we've always used new technologies, we've used science, we've used research and development and discovery to make the old rules obsolete," McCarthy said.
The standards will be open for public comment for 60 days, during which time the agency said, it plans to hold public hearings.
