## Abstract

Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, the Clean Air Act requires states to submit a plan for the implementation, maintenance, and enforcement of the standard, commonly referred to as infrastructure requirements. The Environmental Protection Agency (EPA) is approving the Oregon State Implementation Plan (SIP) as meeting infrastructure requirements for the 2010 nitrogen dioxide, 2010 sulfur dioxide, and 2012 fine particulate matter NAAQS. The EPA is also approving, and incorporating by reference, rule changes made by the state to implement the fine particulate matter NAAQS, relevant to this infrastructure action, and the ozone NAAQS, unrelated to this action, but included for efficiency.
