Proposed Rules to Limit Power Plant Emissions
Source: National Geographic, 19 September 2013
In a move initiated by the Obama administration to address global changes in climate, the U.S. Environmental Protection Agency (EPA) is expected this week to release a proposal for regulations to reduce carbon emissions from new power plants.
Although details about the regulations remain confidential, the New York Times reports the proposal could contain standards different for coal plants than for natural gas power plants. The emissions limits for large natural gas plants may be kept at 1,000 pounds of carbon dioxide per megawatt of electricity produced, as proposed by the agency earlier this spring. The standard for coal, on the other hand, could be closer to 1,300 pounds per megawatt hour.
Regardless of the limits set on Friday, the proposal will give the country its first sense of how carbon capture and storage technology (CCS), which removes carbon dioxide from smokestacks and stores it underground, may be featured in a rule on curbing emissions from existing power plants. The new source performance standards will trigger a section of the Clean Air Act requiring the EPA to work with states to develop standards for existing plants by next summer.
