On June 28, 2012, New York State finalized its rule limiting carbon dioxide emissions from new power plants, and capacity additions to existing plants, within the state. The rule, 6 NYCRR Part 251, would effectively prevent the construction of new coal-fired power plants unless they are combined with carbon capture and sequestration technology. The new state standard is stricter than the federal rule proposed by the U.S. Environmental Protection Agency in April 2012. The regulation takes effect July 12, 2012.
