Abstract
The Environmental Protection Agency (EPA) is approving Illinois' May 8, 2018 request to revise the designation for the entire State of Illinois from unclassifiable to unclassifiable/attainment and Indiana's July 3, 2018 request to revise the designation for the Indiana portions of the Chicago IL-IN and Louisville KY-IN areas from unclassifiable to unclassifiable/attainment for the 2012 primary and secondary annual fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS). EPA is approving these requests because valid, quality-assured, and certified ambient air monitoring data show that the PM<INF>2.5</INF> monitors in the areas are meeting the 2012 primary and secondary annual PM<INF>2.5</INF> NAAQS.
