2022 Emissions Inventory Report
The AQD Online Portal (IMPACT) is the Maricopa County Air Quality Department's (MCAQD) online inventory, monitoring, permitting, and compliance tracking data system. The portal currently supports Title V permits, Non-Title V permits, General permits, Asbestos NESHAP Notifications and Revisions, Emissions Inventory Compliance Reporting, and Performance Testing. The portal allows users to submit and track applications, reports, notifications, and documents electronically to MCAQD.
All 2022 annual EI reports must be completed using the AQD Online Portal (IMPACT). Paper forms will not be accepted.
Please thoroughly review the EI instructions and help sheets and attend an emissions inventory workshop to learn how to access the AQD Online Portal (IMPACT) and complete your 2022 EI report.
The 2022 annual emissions inventory reports are due on Sunday, April 30, 2023 at 11:59 p.m.
