On June 25, 2013, President Obama issued a Presidential Memorandum directing the Environmental Protection Agency (EPA) to work expeditiously to complete carbon pollution standards for the power sector.
The agency is using its authority under section 111 of the Clean Air Act to issue standards, regulations or guidelines, as appropriate that address carbon pollution from new power plants and existing power plants, including modifications of power plants. The Presidential Memorandum specifically directs EPA to build on state leadership, provide flexibility and take advantage of a wide range of energy sources and technologies towards building a cleaner power sector. For newly built power plants, the plan calls for EPA to issue a new proposal by September, 20, 2013, and to issue a final rule in a timely fashion after considering all public comments, as appropriate. For existing plants, the plan calls for EPA to issue proposed carbon pollution standards, regulations, or guidelines, as appropriate, for modified and existing power plants by no later than June 1, 2014 and issue final standards, regulations, or guidelines, as appropriate, by no later than June 1, 2015.
