Ohio Administrative Code (OAC) Chapter 3745-24, NOx and VOC Emission Statements

Contact: Erica Engel-Ishida (614) 644-3631 

  • OAC 3745-24-01 Definitions - Effective Dec. 17, 2016 [PDF]

    Summary of rule: Definitions specific to the emission statement requirements are provided; otherwise, the definitions as they appear in OAC rule 3745-15-01 apply.
  • OAC 3745-24-02 Applicability - Effective Dec. 17, 2016 [PDF]

    Summary of rule: If a facility is located in a county which has been designated nonattainment for the National Ambient Air Quality Standards (NAAQS) for ozone and emits 25 tons or more of volatile organic compounds (VOC) or nitrogen oxides (NOx), an annual emission statement must be submitted beginning with calendar year 1992. In determining whether or not a facility emits 25 or more of NOx or 25 or more of VOC, sources that are exempt pursuant to Section 3704.011(A) of the Ohio Revised Code do not need to be included in the emission estimate. If a county is redesignated to attainment for the NAAQS for ozone, facilities within that county would be exempted from the emission statement requirements beginning with the next full calendar year after the re-designation by U.S. EPA.
  • OAC 3745-24-03 Deadlines for the Submission of the Emission Statements - Effective Dec. 17, 2016 [PDF]
    Summary of rule: The emission statements for calendar year 1992 shall be submitted no later than July 1, 1994. The emission statements for calendar years 1993 through 2004 shall be submitted by Nov. 15 of the calendar year following the year covered by the emission statements. Beginning with reporting year 2005 and each reporting year thereafter, emission statements must be submitted by April 15 of the calendar year following the year covered by the emission statements.
  • OAC 3745-24-04 Emission Statement Requirements - Effective Dec. 17, 2016 [PDF]

    Summary of rule: General facility and specific source information must be included in the emission statements. Estimates of the amounts of emissions actually released to the atmosphere from all sources which are not exempt within the facility must be submitted by an individual who certifies that the information contained in the statement is accurate to the best of his/her knowledge. Sources that are exempt pursuant to Ohio Revised Code (ORC) 3704.011(A) are also exempt from the emission statements. Furthermore, an exemption is provided for research and development sources with a combined potential to emit of less than 5 tons/year for VOC and less than 5 tons/year for NOx or are laboratory or bench-scale research and development sources. This exemption also applies to actual emissions if the owner or operator maintains appropriate records. The information for each source must be submitted using the forms below. Once an area has been redesignated to attainment for ozone or nitrogen oxides emission statement filings are no longer required.

Title V and Synthetic Minor Title V facilities complete the emissions statement requirements as part of the annual fee emissions report.

A site is either Title V, Synthetic Minor Title V, or Non-Title V. Your facility type in turn determines the level of detail, the reporting mechanism (Air Services or hard copy report form) for reporting facility-wide emissions, pollutants included and the amount of fees that are charged. It also determines whether or not an EIS and/or an ES is required to be filed simultaneously.

If your facility is located in a county that has not attained the ozone standard set by U.S. EPA, the Emissions Statement information must be completed. Emissions Statements are required by the Clean Air Act section 182(a)(3)(B) for those that emit greater than or equal to 25 tons per year (TPY) of volatile organic compounds (VOCs) or nitrogen oxides (NOx) during the reporting year. To complete this requirement, give the total TPY where indicated. Visit emissions statement web page for additional information.

 As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at firstname.lastname@epa.ohio.gov or call them directly. The Agency website has contact information for every district, division, and office. In order to reach us, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.
