## Abstract

The Environmental Protection Agency (EPA) is reissuing its final limited approval of the Pennsylvania State Implementation Plan (SIP) to implement the regional haze program for the first planning period through 2018. EPA originally finalized a limited approval of the Pennsylvania regional haze SIP on July 13, 2012. In response to a petition for review of that final action in the United States Court of Appeals for the Third Circuit, EPA successfully moved for a voluntary remand, without vacatur, to more adequately respond to certain public comments. EPA is providing new responses to those comments in this rulemaking notice.
