Air pollution control operation permit renewals FAQ

The following questions and answers explain how to submit an air pollution control operation permit renewal application.

When does a facility need to renew its operation permit?

Many Wisconsin facilities have air pollution control operation permits. Any operation permit that has an expiration date on its cover page will need to be renewed. For permits that require renewal, the permittee must apply for the renewal at least six months prior to permit expiration, but no more than 18 months prior to permit expiration. If a complete operation permit renewal application is submitted to the department in the appropriate timeframe, the facility may continue to operate after the permit expires while the department reviews the renewal application. Title V (major source/Part 70 permits) expire every five years.

Since December 2015, non-Title V operation permits issued after this date do not contain an expiration date. Non-Title V permits issued prior to December 2015 must still submit a timely application for renewal. Upon renewal, they will convert to non-expiring permits, and will not need to be renewed again. Any facility changes throughout time would then be addressed through construction permitting, exemptions and/or operation permit revisions.

What needs to be done to renew a facility's operation permit?

The facility's operation permit may be renewed either by following the process explained in the Instruction Booklet (AM-300) [PDF] or the Electronic Submittal Instructions [PDF] or through the steps below.

Step 1. Write a letter to the Operation Permit Policy Coordinator. Include the following information:

  • any modifications or additions that do not require a construction permit, but need to be included in the operating permit because the maximum theoretical emissions exceed the levels listed in s. NR 407.05(4)(c)10, Wis. Adm. Code [exit DNR]; and/or
  • any new insignificant activities that were added during the 5-year permit term (see s. NR 407.05(4)(c)9, Wis. Adm. Code [exit DNR]); and/or
  • any emission units have been removed from the facility since the operation permit was last issued; or
  • specify that no changes have been made to the facility's emission units; and
  • (optional) redline/strikeout version of the permit, following guidance provided by DNR [PDF].

Step 2. Complete Forms 4530-100 and 4530-102. The forms and associated instructions can also be found on Air permit and compliance forms.

Step 3. Complete forms to provide any information not previously submitted to the department or information that is a revision, correction or update (if applicable). Refer to Forms 4530-101 through 4530-134 on Air permit forms.

Step 4. Complete Form 4530-130 if new requirements have become applicable since the last operation permit was issued. Examples include Compliance Assurance Monitoring (CAM) Rule requirements under 40 CFR Part 64, a Maximum Achievable Control Technology (MACT) rule, etc.

Step 5. Submit the completed operation permit renewal application to the department using either Option 1 or Option 2 below.
