On January 9, 2018, the EPA published the third round of final area designations under the 2010 SO2 NAAQS. In this round, the EPA identified six (6) nonattainment areas located in Florida, Indiana, Louisiana, Puerto Rico and Guam. EPA designated 23 areas as unclassifiable and all other areas as attainment/unclassifiable. The primary focus in this round was on those areas electing to rely on ambient air quality modeling to assess attainment with the standard.
