Many businesses are faithful in getting their construction permits, electrical permits, or mechanical permits for the installation of new structures and equipment form their local building official. However, many of those same businesses may not be aware that an air permit from EGLE's Air Quality Division, may be required for equipment and activities that emit air contaminants.

Michigan Rule 336.1201 (also known as "R201") of the Michigan Administrative Rules for Air Pollution Control (hereafter referred to as the "Michigan Rules") requires a person to obtain a Permit to Install (PTI) prior to the installation, construction, reconstruction, relocation, or modification of equipment that emits air contaminants. Not all sources of air pollution need a permit. In addition to R201, there are numerous other rules exempting insignificant sources of air pollution from having to get permits.

Some important characteristics of the Permit to Install Program are:

  • A permit to install is a state license to emit air contaminants into the ambient air.
  • As long as the facility complies with the condition of the permit, it provides protection of public health and the environment.
  • By going through the permitting process, the applicant will know which state and federal rules apply to the equipment covered under the permit.
  • Conditions of the permit to install limit the potential to emit of the applicant's facility.
  • No fees are associated with obtaining a permit to install. It is free!
  • The permit does not expire (unless stated in the special conditions); it does not have to be renewed. The permit is good for as long as the equipment is in operation. However, it may require notification of completion of the installation, construction, reconstruction, relocation, alteration, or modification.

In addition to the good things, there are some drawbacks associated with the Permit to Install program:

  • Some applications can take many hours to fill out. The amount of time depends on the complexity of the equipment and the type and quantity of emissions of air contaminants.
  • Some facilities may have to hire a consultant to fill out the permit application. This costs money.
  • Depending on the complexity and magnitude of the expected emissions, the application may take several months to issue. That is why it is so important to submit a complete application early in the planning process.
  • To obtain a permit to install, some facilities may have to make operational changes, material substitutions, or install add-on control devices to comply with the applicable rules and regulations.

The Permit to Install program is administered by EGLE's Air Quality Division Permit Section.
