Air Plan Approval; Connecticut; State Implementation Plan Revisions Required by the 2015 Ozone NAAQS

The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Connecticut for the 2015 ozone National Ambient Air Quality Standard (NAAQS). These revisions (1) certify the adequacy of the SIP to satisfy the nonattainment new source review (NNSR) permitting requirements of the Clean Air Act (CAA) for the reclassification of the Greater Connecticut area to moderate nonattainment for the 2015 ozone NAAQS, and (2) certify the emission statement program satisfies the requirements of CAA section 182(a)(3)(B) for the initial nonattainment designations and the reclassification to moderate nonattainment for the 2015 ozone NAAQS. This action is being taken in accordance with the CAA.
