The Maricopa County Air Quality Department (MCAQD) has a new Online Portal for online inventory, monitoring, permitting, and compliance tracking. The portal will allow users to submit and track applications, reports, and documents electronically to MCAQD. Some system functionalities include:
Create and submit an Emissions Inventory
Update facility and contact information
Submit compliance reports
Facilities that are required to submit a 2019 annual emissions inventory (EI) report were notified by email. The email was sent to the contacts for each facility.
All 2019 annual EI reports must be completed using the AQD Online Portal (IMPACT). Paper forms will not be accepted.
MCAQD EI unit collects, reviews, stores, and manages air pollution emissions data for stationary sources in Maricopa County. The EI unit also collects emission fees from Title V sources and provides data to county, state, and federal agencies.
A point source emissions inventory shows annual air pollutant emissions for one specific business location. An emissions inventory may be requested by MCAQD of any facility with an air quality permit in Maricopa County.
Annual emissions inventory report serve a number of purposes:
They help determine a source's compliance with its air quality permit conditions as well as Maricopa County rules and regulations.
They help identify pollutant sources that may need new or additional controls, providing a basis for improved air pollution control strategies.
They also provide a means of assessing progress in achieving reductions from existing controls.
They provide the basis for determining annual emission fees for Title V sources.
Inventory data are used as input for air quality modeling to demonstrate attainment of national ambient air quality standards (NAAQS).
