Permits, Forms, and Payments

Effective July 1, 2021, the Maricopa County Air Quality Department (MCAQD) has transitioned to online permitting and payment processes. MCAQD no longer accepts mailed or emailed applications, registrations, notifications, or payments. These items must be processed directly through the appropriate MCAQD online portal.

Online Permitting Portals and Payments

  1. AQD Online Portal
  2. Dust and Miscellaneous Portal
  3. Paying Permit Fees and Invoices

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

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

To access the AQD Online Portal, the user must create an Electronic Signature account through the Environmental Protection Agencies Shared CROMERR Services (SCS). Once an account has been created, the user will have access to their facility through the AQD Online Portal.
