Summary

On October 14, 2016, the Ohio Environmental Protection Agency (OEPA) submitted a State Implementation Plan (SIP) submission for the 2012 Fine Particle (PM<INF>2.5</INF>) National Ambient Air Quality Standards ("NAAQS" or "standards") for the Cleveland nonattainment area. As required by the Clean Air Act (CAA), OEPA developed an attainment plan to address the Cleveland nonattainment area and evaluate the area's ability to attain the 2012 PM<INF>2.5</INF> NAAQS by the "Moderate" attainment date of December 31, 2021. The SIP submission addresses specific requirements as outlined in the CAA including: Attainment demonstration; reasonable available control measure (RACM) analysis; emissions inventory requirements; reasonable further progress (RFP) with quantitative milestones; and nonattainment new source review (NNSR). Additionally, the SIP submission includes optional PM<INF>2.5</INF> precursor demonstrations for NNSR and attainment planning purposes. EPA has evaluated the SIP submission and is proposing to approve portions of the submission as meeting the applicable CAA requirements for RACM, emissions inventory, attainment demonstration modeling, and precursor insignificance demonstrations for NNSR and attainment planning purposes. EPA is not acting on the other elements of the submission, including reasonable further progress (RFP), with quantitative milestones, and motor vehicle emission budgets (MVEBs).
