Air Plan Approval; Ohio; Source-Specific Non-CTG RACT and SIP Strengthening for Ohio

The Environmental Protection Agency (EPA) is proposing to approve source-specific State Implementation Plan (SIP) revisions submitted by Ohio. These revisions address major source volatile organic compound (VOC) and nitrogen oxide (NO<INF>X</INF>) reasonably available control technology (RACT) requirements for the Cleveland, OH Moderate nonattainment area under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The affected facilities include PPG Industries Ohio, Inc. (PPG), Owens Corning, Akron Paint and Varnish, Charter Steel, U.S. Steel Tubular Lorain, Carmeuse Lime, and Ross Incineration. The EPA is also proposing to approve source-specific SIP revisions for General Electric Aviation Evendale and Tyson Foods for the Cincinnati maintenance area under the 2015 ozone standard. Finally, the EPA is proposing to rescind the source-specific VOC RACT rule for Formica Corporation since it is subject to an equivalent CTG-based rule in the Ohio Administrative Code (OAC).
