Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State Implementation Plan Requirements

a.k.a. Implementation Rule for 2008 Ozone NAAQS - SIP Requirements

RIN: 2060-AR34 (What's this?)

Docket No.: EPA-HQ-OAR-2010-0885 (What's this?)

Current Phase: Proposal (What's this?)

This proposed rule will address a range of implementation requirements for the 2008 National Ambient Air Quality Standards (NAAQS) for ozone, including requirements pertaining to attainment demonstrations, reasonable further progress, reasonably available control technology, reasonably available control measures, nonattainment new source review, emission inventories, and the timing of State Implementation Plan submissions and compliance. Other issues also addressed in this proposed rule are the revocation of the 1997 ozone NAAQS for purposes other than transportation conformity; anti-backsliding requirements that would apply when the 1997 NAAQS are revoked; and routes to terminate the section 185 fee program.
