Permits, Forms, and Applications

The Maricopa County Air Quality Department (MCAQD) recently converted to an online permit application submittal and payment processes.  As of July 1, 2021, MCAQD no longer accepts mailed or emailed applications, registrations, or notifications unless specifically noted below. Instead, these documents must be uploaded directly onto the appropriate MCAQD portal.


The AQD Online Portal is used for new permit applications, renewals, and minor/non-minor modifications for:

  • General/ATO facilities
  • Non-Title V facilities
  • Title V facilities

This portal is also used for submitting asbestos notifications and revisions. Users must create an electronic signature account through Shared CROMERR Services (SCS) to access the AQD Online Portal. 

The Dust and Miscellaneous Portal is used for:

  • Dust control permit applications and changes
  • Subcontractor registrations - new and renewals
  • Open burn applications
  • Tanker truck certifications (vapor decals)

First time users must create an account through the Dust and Miscellaneous Portal.

How can I pay my fees?

Annual administrative fees and billable engineering hours must be paid through the AQD Online Portal. In the case of all other fees, the user will automatically be redirected to the payment page when an application, registration, or notification is submitted through either of MCAQD’s portals.
