General Permit Program

 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 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.

To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946

The Division of Air Pollution Control (DAPC) has developed model general Permits-to-Install (GP) and model general Permits-to-Install and Operate for select sources in Ohio. The regulations for general permits can be found in Ohio Administrative Code OAC rule 3745-31-29. General Permit Fact Sheet [PDF]

A general permit is the same as any Permit-to-Install or Permits-to-Install and Operate that DAPC issues except all the terms and conditions of the permit have been developed in advance. This is referred to as the model general permit. A potential applicant can review the model general permit qualifying criteria and terms and conditions and then complete the application and sign the qualifying criteria document if they believe they qualify for that model GP.

DAPC will review the applicant's information to confirm they meet the qualifications and then issue the model GP to the applicant. At that point it becomes the applicant's general permit. All the terms and conditions of the model general permit remain the same when it is issued as the general permit. The general permit will include a cover page that identifies facility and emission unit specific information. 

Begin by locating the model general permit (GP) of interest using the following steps:

  • Click on the link for the model GP category of interest on the Available Model General Permits tab above.

  • Select the specific model GP of interest within the category desired by clicking on the link for the specific model GP of interest.

The applicant should begin by reviewing the "Qualifying Criteria" document for the model GP of interest. After determining that the source(s) qualifies based on the "Qualifying Criteria" document for the model GP of interest, the applicant should carefully review the terms and conditions of the model GP for which they are applying. The applicant should ensure he or she can comply with the requirements in the model GP as they are written and that they can continue to comply with all other permits previously issued at the source. The terms and conditions of a model GP cannot be modified for site specific conditions. However, the terms and conditions of a previously issued permit, for example a Permit-to-Install (PTI), can be modified if it is necessary in order for the source to comply with the terms and conditions of the model GP. If this is the case for your source, contact your District Office or Local Air Agency for additional information.

Notification of well completion reports, required by the New Source Performance Standards Subpart OOOO, should be submitted at the following email address at least two days before the commencement of well completion operations. This report must contain the information identified in 40 CFR 60.5420(a)(2); and it is recommended that you include the county and the facility ID number, if available.

When the applicant is ready to apply, the following steps should be followed:

  1. Complete and sign the Qualifying Criteria document. The same signatory for the application should sign this document.

  2. Complete the application and any Emissions Activity Category (EAC) form(s). Be sure to read  the application instructions for the specific model general permit for which you are applying. It will provide the applicant with information regarding which sections of the application and EAC form(s) must be completed. Have the signatory, as defined in Ohio Administrative Code (OAC) rule 3745-31-04(B), sign the application.

  3. Include a cover letter that states specifically which model general permit you are applying for, using the "Source Description" and "MGP Number" contained on the Qualifying Criteria document.

  4. Submit a hardcopy of all documents to the District Office or Local Air Agency.
    IMPORTANT: You have the option of applying through Ohio EPA's online Air Services. Applying online eliminates the need to sign and mail paper copies of these forms.

Ohio expects to be able to issue the model GP within 45 days of receipt of a complete application.

As required by the general permit (GP) rules, each model GP will be made available for public comment prior to making it available to the regulated community for application. Listed below is information regarding model GPs that are being developed and are currently available for public comment.

  • Availability of Draft General Permit for Human Crematories.
    The Ohio Environmental Protection Agency, Division of Air Pollution Control (DAPC) is making available a draft model general permit for human crematories with a rated capacity of greater than or equal to 100 pounds per hour, but less than or equal to 200 pounds per hour.

    General air permits contain all the same requirements that would normally be included in traditional air permits, but they can be obtained much more quickly. If the applicant's human crematory meets the qualifying criteria for the human crematory model general permit and they can comply with all the predefined terms and conditions, Ohio EPA will issue a draft general permit for the human crematory. A 30-day comment period will then be held to solicit comments. After the comment period, the Director will decide if a final permit should be issued.

    If you don’t qualify for the model general permit, you can receive a traditional permit that will be similar to the model general permit but will undergo additional review steps not needed for the model general permit. The traditional permit can take additional time to obtain compared to the general permit.

    More information on the general permit process is available electronically for review at:

    DAPC is requesting comments on the draft general permit documents. DAPC will accept comments on the draft general permits through September 17, 2020. Please submit your comments via email to or by mail to:
