Air Quality Division

Revised on: August 17, 2023 - 1:16 am

Our Air Quality Division (AQD) protects Arizona's public health and the environment by controlling present and future sources of air pollution.

AQDs core responsibilities include Air Quality forecasting, monitoring and analyzing data, issuing air permits, compliance inspections, vehicle emissions testing, and asbestos. As well as preserving visibility in urban areas, national parks, and the wilderness. We do this work through our Air Quality Sections.
