Senator James Inhofe (R-OK), ranking member of the Senate Environment and Public Works Committee, in an August 2 letter urged the Environmental Protection Agency to withdraw the carbon dioxide standards for new power plants it proposed in April. Though it is expected that new natural gas-fired coal plants will be able to meet the proposed standard without the need for additional controls, new coal-fired plants would have to to install carbon capture systems to comply. Senator Inhofe’s letter raises several questions about the proposal, including whether the Energy Department agrees that carbon capture for coal-fired plants is viable. The letter requests a response by August 31.
