Who Needs an Air Pollution Permit?

Facilities with equipment that may emit air pollution or is used for controlling air pollution are subject to permit requirements.  The District grants two types of permits:

  • Authority to Construct
  • Permit to Operate

An Authority to Construct must be obtained before building or installing a new emissions unit or modifying an existing emissions unit that requires a permit.

A Permit to Operate is issued after all construction is completed and the emission unit is ready for operation.

Certain equipment is exempt from permit requirements.  A permit is not usually required for repair and maintenance or identical replacement.  District Rule 2020 (Exemptions) lists the types and sizes of devices that are exempt from permitting requirements.

The District has developed a checklist which can provide further guidance in determining the District permitting and notification requirements for your project. Please click here for the checklist.
