Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, the Clean Air Act (CAA) 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 proposing to approve the Oregon State Implementation Plan (SIP) as meeting infrastructure requirements for the 2010 nitrogen dioxide (NO<INF>2</INF>), 2010 sulfur dioxide (SO<INF>2</INF>), and 2012 fine particulate matter (PM<INF>2.5</INF>) NAAQS. The EPA is also proposing to approve, and incorporate by reference, rule changes made by the state to implement the PM<INF>2.5</INF> NAAQS, relevant to this infrastructure action, and also the ozone NAAQS, which is unrelated to this action, but included for efficiency.
The agency’s own summary, as published.
