## Abstract

Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, each state must submit a plan for the implementation, maintenance and enforcement of such standard--commonly referred to as infrastructure requirements. The Environmental Protection Agency (EPA) is approving the May 12, 2015 Alaska State Implementation Plan (SIP) submission as meeting the infrastructure requirements for the 2010 nitrogen dioxide (NO<INF>2</INF>) and 2010 sulfur dioxide (SO<INF>2</INF>) NAAQS.
