## Abstract

The Environmental Protection Agency (EPA) is approving state implementation plan (SIP) revisions submitted by the State of Alaska Department of Environmental Conservation (ADEC) on September 15, 2016. These revisions primarily update adoptions of Federal regulations in the Alaska SIP. The revisions also strengthen the State of Alaska's (Alaska or State) minor source permitting requirements and remove obsolete source-category specific regulations. In addition, EPA is approving SIP revisions to Alaska's general and transportation conformity regulations submitted by ADEC on March 10, 2016. The EPA is taking action only on the conformity related portions of the March 2016 submittal. The other portions of the submittal are or will be addressed in separate actions.
