Air Quality Division

The Air Quality Division (AQD) supports efforts to maintain clean air and minimize adverse impacts on public health and the environment. Staff work to reduce existing outdoor air pollution and prevent the worsening of air quality through our programs which evaluate, measure, permit, monitor, regulate, and inspect sources of air emission.  AQD staff strive to serve our diverse stakeholders through outreach, communication, and continuous improvement. Read more about our work in the 2022 Air Quality Division Year in Review.
