About the Division of Air Quality


The mission of the Department of Environmental Quality (DAQ) is to safeguard human health and quality of life by protecting and enhancing the environment.


A quality environment will be achieved through:

  • Careful, open, and fair consideration of the concern of all Utahns
  • Excellence in science, communications, and operations
  • Timely, effective, and consistent response to all customers
  • Actively promoting pollution prevention


The Division of Air Quality is divided into three separate branches.

Permitting Branch

The Permitting Branch is responsible for issuing two kinds of permits, construction, and operating permits. Construction permits are issued to new or modified sources of air pollution through the New Source Review program. Operating permits are issued, on an ongoing basis, through Title V of the CAA.

Planning Branch

The Planning Branch is responsible for developing comprehensive plans (State Implementation Plans) to reduce air pollution. Emissions inventories are routinely compiled in order to understand the origins of the various contaminants detected in the air. Computer models (Technical Analysis) are used to evaluate the impacts of new and existing sources of air pollution, and to understand the relationship between the emissions, meteorology, and pollutant concentrations measured in the air. The branch is also involved in identifying the air quality impacts of transportation issues (Mobile Sources) which include vehicle inspection and maintenance, clean fuels, and highway construction. This information must be considered in the development of State Implementation Plans (SIPs) in order to ensure that Utah’s ambient air remains in compliance with the federal health standards, even as our population and our economy continue to grow.

CARROT Grant Program

The Clean Air Retrofit, Replacement, and Off-Road Technology Grant Program is designed to incentivize individuals, businesses, and local government to reduce emissions from vehicles and equipment.

Compliance Branch

The Compliance Branch is responsible for ensuring that industries and residents are complying with all Utah Air Quality requirements. The branch also monitors mitigation activities associated with asbestos and lead-base paint (Hazardous Air Pollutants). The Air Standards Branch also includes Air Monitoring Center operates a network of air quality monitors throughout the state. The Small Business Assistance Program has been set up within the Air Standards Branch to help small businesses deal with the many requirements surrounding air quality, including the various permitting requirements.
