OAC 3745-14 - Nitrogen Oxides - Budget Trading Program Contact:  Lee Burkleca 614-728-1344 Ohio EPA, with the assistance of the Ohio Department of Development's Office of Energy Efficiency, has developed a guidance manual to assist those interested in applying for and obtaining NOx allowances from the Energy Efficiency/Renewable Energy and Innovative Technology set-asides.  These set-asides are provided in Ohio's NOx Budget Trading Program rules in Ohio Administrative Code ("OAC") Chapter 3745-14 and will be available for projects during the 2006 ozone season, May 1 through September 30. If you have questions about the program or the application process, please contact Lee Burkleca at 614-728-1344. OAC 3745-15 - General Provisions on Air Pollution Control Contact: Mike Ahern  614-644-3631 Drafts and Notices for this Chapter June 9, 2008: Ohio EPA has refiled amended language for OAC rules 3745-15-01, 3745-15-02, 3745-15-04 through 3745-15-06, 3745-15-08, and 3745-15-09.

Ohio EPA is proposing amended OAC rules 3745-21-01 to 3745-21-04, 3745-21-06, 3745-21-08 to 3745-21-16 and 3745-21-18. Ohio EPA is also proposing new OAC rules 3745-21-19 to 3745-21-23. These rules are related to the control of emissions of carbon monoxide, photochemically reactive materials, hydrocarbons, and related materials. The rules are being amended as a result of the requirements of Ohio Revised Code (ORC) 119.032 for 5 year review and as a part of Ohio's control strategy for volatile organic compounds (VOCs) in the Cleveland/Akron metropolitan area as required by our State implementation Plan. The package also contains an amendment to paragraph (U)(2)(f) of rule 3745-21-09 to address concerns raised by USEPA regarding the establishment and stakeholder review process of these types of alternative emissions limitations. The rules are being proposed after a public comment period of 30 days which ended August 23, 2006, and a public comment period of 30 days for the change to 3745-21-09(U)(2)(f) which ended October 11, 2007.  Several comments were received during both comment periods.

This paragraph is related to alternative emissions limitation(s) to the miscellaneous metal coating limits under OAC rule 3745-21-09(U)(1) which apply to a broad range of operations, including exceptional cases where these limits may not be reasonably achievable. Ohio EPA has the authority under ORC 3704.03(E) to establish alternative emission limitations. Our preliminary review indicates that this paragraph continues to be necessary and is in need of amendment. DAPC is proposing these changes to address concerns raised by USEPA regarding the establishment and stakeholder review process of these types of alternative emissions limitations. We are accepting comments on the draft amendments through Thursday, October 11, 2007. Please see the synopsis and draft amendment language, and the interested party notice, both below, for additional information on the draft language and details on submitting comments. Interested Party Notice Synopsis of Changes and Draft Amendments. July 21, 2006: Ohio EPA has completed a review of various rules in Ohio Administrative Code (OAC) Chapter 3745-21 to satisfy the requirements of R.C. 119.032 (five-year review). These rules are related to the control of emissions of carbon monoxide, photochemically reactive materials, hydrocarbons, and related materials. We find the rules to be necessary and with need of amendments. Ohio EPA is proposing to amend OAC rules 3745-21-01 to 3745-21-04, 3745-21-06, and 3745-21-08 to 3745-21-18. Ohio EPA is also proposing new OAC rules 3745-21-19 to 3745-21-23. Ohio EPA is proposing the amendments and new rules to meet the minimum requirements associated with adopting RACT requirements for the Cleveland/Akron moderate nonattainment area. These requirements were promulgated in U.S. EPA’s rule for implementation of the eight-hour ozone standard published in the November 29, 2005 Federal Register (70 FR 71612). We are accepting comments on the proposed actions through August 23, 2006.  Please see the rule language, synopsis and public hearing notice, all below, for information on the rule changes and how to submit comments.

Ohio EPA is proposing amended OAC rules 3745-100-01, 3745-100-02, 3745-100-07, 3745-100-09, 3745-100-11, 3745-100-14, and 3745-100-15, proposing to rescind and replace with new text OAC rule 3745-100-05, and proposing new OAC rule 3745-100-17. These rules are being amended and/or promulgated as new as a result of two new rules finalized by the USEPA during reporting year 2006, for reporting year 2006. First, USEPA Toxic Release Inventory (TRI) finalized the “TRI NAICS Rule”, which requires TRI facilities to report North American Industry Classification System (NAICS) codes on their submissions instead of Standard Industrial Classification (SIC) Codes. Additionally, TRI also finalized the TRI Burden Reduction Rule which expands the eligibility for use of the Form A Certification Statement in lieu of the more detailed Form R. The rules are being proposed after a public comment period of 30 days which ended December 10, 2007. No comments were received on the draft rule language. We are holding a public hearing on the new and amended rules at 10:00 AM on Monday, August 18, 2008 in Conference Room D, 6th Floor, Ohio EPA, Lazarus Government Center, 50 W.

These rules are related to the Clean Air Interstate program which is Ohio’s implementation of the federal Clean Air Interstate Rules (CAIR) as first published in Volume 70 of the Federal Register, Page 25162 (70 FR 25162). These changes are necessary as a result of comments submitted by US EPA after the end of Ohio’s CAIR final rulemaking process. In addition, revisions were made to US EPA’s final CAIR rule on October 19, 2007 (72 FR 59190) that will also be incorporated into Ohio’s CAIR rules during this rulemaking.
