Indirect Source Permit Application

The permit application process involves several steps starting with a preliminary meeting and ending with permit issuance. The average permit process time varies between 90 to 120 days depending on complexity and application completeness.

Step 1. Meet With DNR

The permit applicant shoud meet with DNR after obtaining the necessary information to start the project. At the initial meeting the DNR will discuss which areas should be modeled, the modeling parameters, and anticipated time when the permit application review can be completed.

Step 2. Supply Permit Application and Application Fee

The applicant should supply a permit application and application fee. The permit application should contain the following information:

  • Written and graphical representation of the project
  • Traffic analyses and forecasts pertinent to the project
  • Modeling input and modeling output files. This information can be emailed to Michael Friedlander.
  • Description of calculations and assumptions
  • Summary of results
  • Indirect Source application fee

Step 3. DNR Review

After the DNR has deemed the indirect source permit application as complete (i.e. all of the information necessary to verify the results have been supplied by the applicant), DNR will review the information. If DNR agrees with the information then a draft permit and a draft environmental assessment will be completed.

Step 4. Public Review and Permit Issuance

DNR will supply an option to the applicant to hold or not hold a public hearing on the draft permit and environmental assessment. If the applicant chooses not to hold a hearing, either DNR or the applicant will publish in a newspaper which generally reports information for the area in which the project is proposed, a Class 1 legal notice regarding the permit. If no comments are received, DNR will proceed in issuing the permit. If comments are received, DNR will take these comments into account and determine whether the proposed permit needs to be modified. Note: At any time during the public comment period a concerned party can request a public hearing and DNR, as required by statute, must hold the public hearing.
