All applications should be submitted through the SCS portal. Instructions for the portal can be found on air quality web page.

Annual Administrative and Air Quality Permit Fees
Do not attempt to pay fees unless you have received an invoice from the department. You will need the invoice to accurately submit your permit number, business name, and balance due.

If you need assistance in filling out the applications please contact permitting by phone at 602.506.6010 or by email at AQPermits@maricopa.gov

Important: To protect the security of your information, you must have a current or nearly-current browser and operating system. If you do not, the online payment portal will not allow you to submit a payment. See our Supported Browsers and OS page for more information.
