## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Alaska State Implementation Plan (SIP) submitted by the Commissioner of the Alaska Department of Environmental Conservation (ADEC) on December 11, 2009, November 29, 2010, December 10, 2012, January 28, 2013, July 1, 2014, and October 24, 2014, to meet Clean Air Act (CAA) requirements. These revisions update Alaska's adoption by reference of the Federal preconstruction permitting regulations for large industrial (major source) facilities located in designated nonattainment areas, referred to as the Nonattainment New Source Review (major NNSR) program. The major NNSR program is designed to ensure that major stationary sources of air pollution are constructed or modified in a manner that is consistent with attainment and maintenance of the National Ambient Air Quality Standards (NAAQS).
