AQD Online Portal (IMPACT)

This page will be updated regularly as the department transitions to the new Online Portal. Additional documents and information will become available as needed.

To Access your Facility on the AQD Online Portal

Facilities will need to create a Shared CROMERR Services (SCS) Account to complete Emissions Inventory, and access General Permits, Non-Title V Permits, and Title-V Permits. See the guide below for instructions on creating a SCS Account.

*Reminder: The access and use of an SCS Account for electronic submittal requires the creation of a user ID and password that must be kept confidential. An SCS Account is for individual use only, and cannot be shared or accessed by anybody other than the original account owner. For more information, see the SCS Terms and Conditions.

All consultants must register their organization/company before attempting to create an SCS Account. Please fill out and submit the form below.

If your organization/company has never had a permit with the Maricopa County Air Quality Department (MCAQD), or if you have recently changed ownership, you will need to submit a New Account Form in order to create an SCS Account. Please fill out and submit the form below.
