National Emission Standards for Hazardous Air Pollutants for Coal- and Oil-fired Electric Utility Steam Generating Units

Docket ID: EPA-HQ-OAR-2009-0234
Agency: Environmental Protection Agency (EPA)
On May 18, 2005 (70 FR 28606) , EPA published a final rule requiring reductions in emissions of mercury from Electric Utility Steam Generating Units. That rule was vacated on February 8, 2008, by the U.S. Court of Appeals for the District of Columbia Circuit. As a result of that vacatur, coal- and oil-fired electric utility steam generating units remain on the list of sources that must be regulated under section 112 of the Clean Air Act (CAA). The Agency will develop standards under CAA section 112(d) which will reduce hazardous air pollutant (HAP) emissions from this source category. Recent court decisions on other CAA section 112(d) rules will be considered in developing this regulation. The rule was proposed on May 3, 2011 (76 FR 24976).Under this action EPA also proposed amendments to the criteria pollutant new source performance standards (NSPS) for utilities. On February 27, 2006, EPA promulgated amendments to the utility NSPS and was subsequently sued by multiple state attorney general offices and environmental organizations. On September 2, 2009, EPA was granted a voluntary remand without vacatur of the 2006 amendments. Combining the two rules is a single action provides interested parties the opportunity to provide comments on the combined requirements of the 2 rules. It also avoids double counting either costs or environmental benefits of the separate rules.
