Public Notice Ohio Environmental Protection Agency Re designation and Maintenance Plan for the Columbus , Ohio Ozone Nonattainment Area Delaware, Fairfield, Franklin, Knox, Licking, and Madison Counties Notice is hereby given that the Director of the Ohio Environmental Protection Agency, (Ohio EPA) is requesting that the United States Environmental Protection Agency (U.S. EPA) revise the current air quality designation for the Columbus , Ohio area ; Delawar e, Fairfield, Franklin, Knox, Licking and Madison counties to attainment with respect to the 2008 eight

- hour ozone national ambient air quality standard (NAAQS)

. Air quality monitoring data collected between 2012 and 2014 in the region demonstrate d attainment of the NAAQS and there was evidence that the improved air quality is due to permanent, e nforceable emission reductions. In addition, existing requirements are sufficient to maintain the 2008 eight

- hour ozone standard in this area at least ten y ears into the future

. Projected emissions and c omputer models show that existing state and federal emission reduction requirements are sufficient to attain and maintain the NAAQS in the C olumbus area. Therefore, Ohio EPA proposes to utilize existing emissi on inventory information and projections of future emissions as the demonstration of the ability to maintain the NAAQS in the Columbus area in the future. The Columbus area is currently designated as nonattainment for the 2008 ozone standard. As part of an acceptable maintenance plan, Ohio EPA is required to develop a contingency plan to provide for additional emission reductions if a violation of the NAAQS is monitored after the area has been redesignated. The plan which Ohio EPA is proposing to U

. S

. EPA as part of this redesignation contains reductions which will help alleviate the ambient problem until a revised SIP can be developed. The State of Ohio proposes to: 1. Request the U.S. EPA redesignate the Columbus area to attainment with respect to the 2008 ozone NAAQS an d revise the maintenance plan. This request will document that existing enforceable control measures are responsible for the observed improvement in air quality. 2. Designate existing controls as suff icient to maintain the NAAQS into the future. 3. Commit to the proposed contingency plan. These actions must be noticed to allow public comment and to satisfy U.S. EPA requirements for public involvement in SIP related activities. This notice addresses Ohio EPA’s reliance on the emission project ion s as evidence of attainment and maintenance and the commitment to institute contingency measures if ambient exceedances or violations trigger the contingency plan requirements.

- assured ambient air pollu tion data (2012

- 2014) demonstrating attainment of the eight

- hour standard based on the requirements laid out in Section Ohio EPA held a public hearing in Columbus, OH on June 2 , 2016, regarding the 2008 8
