How to apply for air permits

A permit application is required for each facility that emits air pollution, unless the facility qualifies for a permit exemption. However, some air permit exemptions also require an application. For more information on which permit options you need, visit the Air permit options.

Construction permits

Construction permit applications and construction permit exemption determination requests have initial application fees. The application process and payment structure is explained on the Construction tab of the Air permit options page.

Operation permits

Operation permit applications and operation permit exemption determination requests do not have initial application fees. There are three types of operation permits: Registration Operation Permits (ROPs), General Operation Permits (GOPs) and source-specific operation permits.

  • ROPs and GOPs have specific application forms for each permit type available.
  • Source-specific (e.g., exemption, operation permit, construction permit) applications always require the use of Form 4530-100 [PDF]. Depending on what is being applied for, other "source specific" forms may be required. Please read the form-by-form instruction [PDF] for additional information.

Operation permit renewals

An operation permit renewal application is only required for operation permits with an expiration date on the cover page.

Please refer to the Renewal page for instructions on how to submit an operation permit renewal application to the department.

Permit exemptions

Some activities and types of facilities or operations are exempt from needing a construction permit or an operation permit. If a facility determines it is exempt, in most cases, a formal exemption application is not required and the facility can simply submit an application to revise their existing operation permit to incorporate the exempt activity and proceed with the project. Because of the complexities of the exemption regulations and the compliance concerns over constructing without a permit, most facilities apply for a formal exemption determination from the department. Use Form 4530-100 [PDF] to apply for exemptions.

Importantly, there are several types of exemptions where a formal application must be submitted to and determination made by the department before a project can proceed:

  • research and testing exemptions under s. NR 406.04(1)(i);
  • ten ton exemption from construction permitting under s. NR 406.04(1q);
  • ten ton exemption from operation permitting under s. NR 407.03(1m), where facility-wide emissions exceed reporting thresholds in ch. NR 438 and/or the facility has applied for or has been issued a facility-wide operation permit; and
  • natural minor exemption under s. NR 407.03(1s).

Application forms for all types of air pollution control permits are available in Adobe PDF and Microsoft Word on the Air permit and compliance forms page.

The Air permit options page has application process information for construction permit, operation permit, registration (ROP), general (GOP) and exemption applications.
