Request for Input on Annual Modeling Guidance Revision

The Minnesota Pollution Control Agency (MPCA) will begin the annual revision of its modeling guidance and forms this spring. At this time, we would like to hear your thoughts and experiences on the existing guidance and forms, as well as any suggestions you have to update or improve existing modeling practices and program features. We will be collecting your comments through the end of March. We anticipate having a draft version of the updated MPCA Modeling Guidance and Forms available for public review and comment in early June. The existing Guidance and forms can be found on the MPCA’s air quality dispersion modeling webpage.  As you review the documents, please consider the following:

  • What has worked well?
  • What has not worked well?
  • What would you change?

Please feel free to contact any of our modeling staff with questions. You may provide your comments to us at

Thank you for your time and expertise!
