Title: National Emission Standards for Hazardous Air Pollutants for Coal- and Oil-Fired Electric Utility Steam Generating Units | |
Abstract: 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. | |

Statement of Need: Section 112(n)(1)(A) of the Clean Air Act required EPA to conduct a study of the hazards to public health resulting from emissions of hazardous air pollutants from electric utility steam generating units and, after considering the results of that study, determine whether it was appropriate and necessary to regulate such units under section 112. The study was completed in 1998 and in December 2000, EPA determined that it was appropriate and necessary to regulate coal- and oil-fired electric utility steam generating units and added such units to the list of sources for which standards must be developed under section 112. The February 8, 2008, vacatur of the May 18, 2005, Clean Air Mercury Rule and March 29, 2005, section 112(n) Revision Rule (which had removed such sources from the list) resulted in the requirement to regulate under section 112 being reinstated. |
