Bloomberg BNA -- The Environmental Protection Agency is scheduled to publish reproposed carbon dioxide limits for new power plants on Jan. 8, setting separate standards for coal-fired and natural gas-fired generating units.

EPA announced the proposal Sept. 20, but it had not yet been published in the Federal Register.

The rule would revise an April 2012 proposal, in which the EPA had intended to set a single standard of for both coal- and gas-fired plants.

The new plant performance standards aren't expected to result in significant carbon dioxide emissions reductions because the power sector is already investing in cheaper, cleaner natural gas-fired units. However, finalizing the new plant performance standards would trigger a requirement under Section 111(d) of the Clean Air Act for the EPA to issue similar emissions guidelines for existing units.

Power plants are the largest source of greenhouse gas emissions in the United States.
