## Abstract

The Environmental Protection Agency (EPA) is correcting a final rule that appeared in the Federal Register on March 18, 2016 (81 FR 14736). The document included a listing of areas for which states had not submitted State Implementation Plans (SIPs) addressing nonattainment area SIP requirements for the 2010 1-hour primary sulfur dioxide (SO<INF>2</INF>) NAAQS. This action corrects that listing to clarify that the Indiana, Pennsylvania nonattainment area for the 2010 SO<INF>2</INF> NAAQS consists of the entirety of Indiana County and part of Armstrong County.
