Instructions for air permit applications

Starting July 1, 2020, Individual permit holders must use e-Services to apply for reissuance. Paper reissuance applications will only be accepted if there is a request for confidentiality. Email AQApplicationFormsRequest.pca@state.mn.us to request the paper application forms.

Complete applicable application forms for your permit or amendment type. Instructions are included with each form. If you need assistance, call the MPCA at 651-296-6300 or 800-657-3864.

Submit your application on paper, CD or USB drive.

  • If on paper, submit two copies.

Submit your application to:

MPCA — Fiscal Services

If you are requesting construction authorization

Permits authorizing construction have a 150-day goal for issuance. Your permit may require more than 150 days if it involves:

  • PSD permitting;
  • Air dispersion modeling for criteria air pollutants or air toxics;
  • Environmental Review. Complete this pre-screening form to determine if environmental review is required [an Environmental Assessment Worksheet (EAW) or Environmental Impact Statement (EIS)]: File Environmental Review pre-screening form (p-ear1-08)
  • Air Emissions Risk Analysis (AERA);
  • An otherwise complex technical or regulatory analysis; or
  • A potentially controversial change.

The MPCA offers an expedited permit process for certain types of projects. If you need a permit issued faster than the 150-day goal, contact Steve Pak at 651-757-2633.

If you are conducting air modeling

The final modeling results will need to be included in the permit application. Before you submit your application, you will need MPCA approval of your modeling protocol. See the Air Quality Dispersion Modeling webpage for forms and information on pre-application approvals. If you have questions about the air modeling forms and process, please contact Jim Sullivan at 651-757-2769.

If you are conducting an AERA

The final Air Emissions Risk Analysis (AERA) results will need to be included in the permit application. Before you submit your application, you will need MPCA approval of the AERA protocol. Refer to AERA forms and tools; if you have questions about the AERA forms and process, please contact Jim Sullivan at 651-757-2769.

If you are requesting confidentiality

If your application includes confidential information, submit two versions of the application. One version with the confidential information and one public version with the confidential information redacted. If you are using the electronic submittal option, your public and confidential versions need to be on separate CDs.

If you are located in the city of Minneapolis

You will need to determine if your facility is subject to requirements under Minn. Stat. 116.07, subd. 4a. For more information, go to Cumulative Impacts Air Permitting in South Minneapolis.

If you need to submit a mercury reduction plan

If your facility is a “mercury emission source” as defined in Minn. R. 7005.0100, subp. 23b and emits more than 3 lbs. of mercury (or 5 lbs. for Industrial boilers), you need to determine whether you must submit a mercury reduction plan under Minn. R. 7007.0502. Facilities that are not ferrous mining or processing must submit a plan by June 30, 2015. If you need to prepare and submit a Mercury Reduction Plan to comply with Minn. R. 7007.0502, please use one of these forms:

Learn more about mercury reductions and MPCA's plan to reduce mercury releases by 2025.

If you need to assign new designation numbers

The following principles apply to item numbering in applications:

  • Permitted items must be numbered consecutively. New items must use the next number after the last one used in your current permit or in the most recent MPCA Emission Inventory.
  • In permits issued prior to November 1, 2015, items will be designated EU, CE, SV, GP, MR, DA, CM, FS, or TK. In permits issued after November 1, 2015 items will be designated EQUI, TREA, STRU, FUGI, or COMG.
  • Continue to use the designations used in your current permit.
  • You may not re-number items already listed in a permit or Emission Inventory.
  • A number used for an item that will be retired, removed, or replaced is no longer available to use.

If you have questions about what designation number (EUxxx, CExxx, SVxxx, etc. or EQUIxxx, TREAxxx, STRUxxx, etc.) to use for new equipment at an existing facility, contact the Air Quality Permit Writing Assistant at beckie.olson@state.mn.us and provide the following:

  • Facility name and ID number (8-digit portion of the permit number);
  • What you want to know (e.g., the next available EU or EQUI number, the next available CE or TREA number, etc.); and
  • If you have submitted an unprocessed permit application and whether that application involves removing, replacing, or adding equipment.

If you need assistance

Visit the All About: Permits page for information about

  • who needs a permit;
  • determining the appropriate permit type for your facility;
  • descriptions of the types of operating permits;
  • the types of permit amendments and when they are needed; and
  • how the permit process works.

The Small Business Environmental Assistance Program has a variety of resources available to many businesses. SBEAP cannot provide an official determination of whether a permit is needed, or what type of permit to apply for. They can, however, show you how to find information needed to make those decisions. Facilities with very low emissions may qualify as one of the conditionally exempt source categories provided they comply with all general and technical standards as outlined in Minn. R. 7008.2000.

If you would like to see any permit on public notice

Visit the Public Notices page

If you would like an official MPCA determination

Complete and submit Form CH-16 (available below, under section 2) to obtain an official agency determination on whether you need a permit or permit amendment, or how a specific rule applies. Include all information and forms requested in the form.

Completeness review

Your application will be reviewed for completeness. You will receive information about the status of your application after the completeness review.

If mandatory fields are left blank in your application forms, the application will be deemed incomplete and returned.

MPCA staff use the following checklists for the completeness review. Do not submit a completeness checklist with your application or applicability request.)

The Part 70 Manufacturing General Permit is intended for stationary sources with these process operations: abrasive blasting, boilers, brazing, casting, catalytic or thermal oxidizers, cleaning (including acid cleaning, degreasers, general cleanup with solvents), dip tanks, fabric filters, fuel storage, furnaces, injection molding, internal combustion engines (generators), lamination, mixing, molding, ovens, resin and gel coating, sanding, screen printing, soldering, space heaters, spraying and coating activities, stenciling, storage tanks, wall/panel filters, paint booths, and welding.

C. Part 70 Low-emitting Facility General Permit (January 2015)

The MPCA is no longer accepting applications for Part 70 Low-emitting Facility (LEF) General Permits. The LEF Permit will expire on April 30, 2020. Because of the rescission of “Once in Always in” and the promulgation of additional conditionally exempt source categories in Minnesota Rules Chapter 7008, the MPCA does not plan to replace the LEF permit. Current LEF general permit holders will be required to apply for a new permit or become a conditionally exempt source by November 2, 2019; permittees may still continue to operate their facility after the expiration date of the permit, as long as they have applied for a replacement option by Nov. 2.

We expect most current LEF holders to be eligible for one of the following:
