PUBLIC MEETING | EPA’s Proposed Ozone Implementation Rule

The Environmental Protection Agency (EPA) is proposing nonattainment area classification thresholds and implementation requirements for the strengthened 2015 ozone national ambient air quality standards (NAAQS) (2015 ozone NAAQS) that were promulgated on October 1, 2015. This proposal is largely an update to the implementing regulations previously promulgated for the 2008 ozone NAAQS, and we propose to retain without significant revision the majority of those provisions to implement the 2015 ozone NAAQS. This proposal addresses the timing of attainment dates for each nonattainment area classification and a range of nonattainment area state implementation plan (SIP) requirements for the 2015 ozone NAAQS. The proposed SIP requirements pertain to attainment demonstrations, reasonable further progress (RFP) and associated milestone demonstrations, reasonably available control technology (RACT), reasonably available control measures (RACM), major nonattainment new source review (NNSR), emission inventories, the timing of required SIP submissions, and compliance with emission control measures in the SIP. Other issues addressed in this proposed rule are the revocation of the 2008 ozone NAAQS, anti-backsliding requirements that would apply when the 2008 ozone NAAQS are revoked, and reconsideration of the ozone NAAQS interprecursor trading (IPT) provisions (in response to a petition for reconsideration).
