General Permit Program

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.
