State Implementation Plan (SIP) - 2010 One-hour SO2 Standard

On June 22, 2010, U.S. EPA strengthened the National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). U.S. EPA set a new one-hour primary SO2 standard at 75 ppb and revoked the existing annual and 24-hour primary standards (for which Ohio had been in full attainment).

On August 21, 2015 USEPA published the final Data Requirements Rule for the 2010 SO2 standard. [80 FR 51052] This rule will require Ohio EPA to characterize SO2 emissions around sources not located in nonattainment areas but with the potential to impact compliance with the 2010 SO2 standard. This characterization will be either through monitoring or modeling. Based upon the DRR, under 40 CFR 51.1203, each state is required to submit a list of applicable SO2 sources identified pursuant to 40 CFR 51.1202 by January 15, 2016.

The August 21, 2015 Data Requirements Rule for the 2010 SO2 standard [80 FR 51052] established ongoing data review requirements including, for areas where modeling of actual SO2 emissions served as the basis for an unclassifiable/attainment designation, an annual review of emissions data and submittal of a report recommending whether updated modeling is necessary due to emissions increases. The annual emissions review is due to U.S. EPA Region 5 by July 1, annually, beginning the calendar year after the effective date of designation.

Redesignations and Maintenance Plans

 

 

Availability of Draft Redesignation Request and Maintenance Plan for the Muskingum River, OH Sulfur Dioxide Nonattainment Area
February 1, 2018: Ohio EPA is providing for public comment a draft redesignation request and maintenance plan for the Muskingum River, OH SO2 Nonattainment Area. Air quality monitoring data collected between 2015 and 2017 in the area demonstrate attainment of the NAAQS and there is evidence that the improved air quality is due to permanent, enforceable emission reductions. In addition, existing requirements are sufficient to maintain the 2010 1-hour SO2 standard in this area at least ten years into the future. Due to this evidence DAPC will be asking U.S. EPA to redesignate the Muskingum River, OH area as attainment for the 2010 1-hour SO2 standard and approve Ohio's maintenance plan.

Ohio EPA will be providing a public comment period on the draft plan through March 7, 2018. A public hearing on this action may be requested by contacting Holly Kaloz at (614) 644-3632 or holly.kaloz@epa.ohio.gov no later than March 7, 2018. If a public hearing is requested, a new notification will be published to identify the time and location of the public hearing. The public hearing will be held at least 30 days after the date of the new notification. For information on how to submit comments or request a hearing please refer to the public notice.
