AQD Online Portal

Accessing the AQD Online Portal


STEP 1: Review the video or the PDF guide below for creating your SCS electronic signature through the Environmental Protection Agencies Shared CROMERR Services (SCS) electronic reporting site. Skip to Step 2 if you already have an existing SCS electronic signature.

If your organization/company has never had a permit with the Maricopa County Air Quality Department (MCAQD), or if your organization/company has recently changed ownership, please complete and submit the Shared CROMERR Services (SCS) Electronic Signature Registration Form before attempting to create your SCS electronic signature. Do not fill out this form if your organization/company already has a current permit with MCAQD. 

Individual consultants and performance testing companies must register themselves as an organization/company before beginning the process of creating a SCS electronic signature.

STEP 2: Login to your electronic signature account to access the AQD Online Portal. 

STEP 3: Access applicable guidance documents from resource links below to navigate through the portal.
