## 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) finds that the Idaho State Implementation Plan (SIP) meets the infrastructure requirements for the 2012 fine particulate matter (PM<INF>2.5</INF>) NAAQS.
