On February 16, 2012, the EPA issued the National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial-Commercial-Institutional Steam Generating Units, generally referred to as the mercury and air toxics standards (MATS Rule), which established emissions standards for new and existing coal- and oil-fired electric utility steam generating units.
On July 20, 2012, the EPA issued a letter, stating its intent to grant the petitions for reconsideration on certain new source issues related to the emission standards issued under Clean Air Act section 112, including measurement issues related to mercury and the data set to which the variability calculation was applied when establishing the new source standards for particulate matter and hydrochloric acid.
This action stays the effectiveness of national new source emission standards for hazardous air pollutants from coal- and oil-fired electric utility steam generating units that were published in the Federal Register on February 16, 2012 (77 FR 9304).
DATES: This action is stayed until November 2, 2012.
