The Environmental Protection Agency (EPA) is establishing air quality designations in the United States (U.S.) for the 2012 primary annual fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) for the remaining undesignated areas in the state of Tennessee. When the EPA designated the majority of areas in the country in December 2014, and March 2015, the EPA deferred initial area designations for several locations, including all of the state of Tennessee except three counties in the Chattanooga area, because the EPA could not determine using available data whether the areas were meeting or not meeting the NAAQS. However, we believed that forthcoming data in 2015 would allow the EPA to make that determination. Tennessee has now submitted complete, quality-assured, and certified air quality monitoring data for 2015 for the areas identified in this document, and based on these data, the EPA is designating these areas as unclassifiable/attainment for the 2012 primary annual PM<INF>2.5</INF> NAAQS.
