  • Performance Audit of Sand and Gravel:
    Air Quality Permitting and Compliance

    A July 2013 Legislative Performance Audit of sand and gravel permitting raised concerns about Division of Air Quality (DAQ) enforcement of in-process permits, case management of permit modification requests, and the timeliness of processing permit applications

  • School Bus Program:
    Be Idle Free

    In a landmark effort that has become a model for other states, the Utah State Office of Education, in partnership with the Utah Clean Cities Coalition, has developed a state school bus idle reduction program that has schoolchildren, their parents, and bus drivers cheering … and breathing deeply

  • Some Common Myths:
    Be Idle Free

    Many people are unaware that reducing the time a vehicle spends idling can make a big difference in both air quality and fuel costs.

  • Health Effects:
    Be Idle Free

    Idling can be bad for your health. While children, the elderly, and people with respiratory ailments are most vulnerable to the pollutants from vehicle exhaust, these emissions affect everybody.

  • Be Idle Free

    Idling your vehicle gets you nowhere. It increases our dependence on petroleum, reduces the fuel economy of your vehicle, costs you money, emits pollutants, and wastes precious natural resources.

  • National Emission Standards for Hazardous Air Pollutants (NESHAPs):
    Hazardous Air Pollutants and Small Business

    NESHAPs are regulations that regulate specific processes, like dry cleaners, that use specific chemicals, like perchloroethylene, called a hazardous air pollutant. If you can change your chemicals to a chemical that is not one on the list of HAPs you can avoid the rule. Below are the most commonly used small business NESHAPs with customized…

  • Air Quality Modeling Program

    Why Do We Need Models? The Division of Air Quality regularly measures the concentration of specific air pollutants at selected monitoring locations. However, the Division also needs the ability to make future projections of air pollution levels. Computer models are a relatively inexpensive and expedient means of providing this air quality information. For example, models…

  • Geographic Information Systems (GIS):
    Air Quality Modeling Program

    The Division has used Geographic Information Systems (GIS) for air quality modeling studies since 1993 by creating its own database of relevant spatial layers. This data helps in the creation of emission inventories for ozone and fine particulate modeling. This is done through the creation of demographic surrogates so that county-wide emissions can be further…

  • Exceptional Events Program

    Exceptional events are unusual or naturally occurring events that can affect air quality but are not reasonably controllable using techniques tribal, state or local air agencies may implement in order to attain and maintain the National Ambient Air Quality Standards. Exceptional events are events for which the normal planning and regulatory process established by the…

  • Fireworks:
    Exceptional Events Program

    The Division on Air Quality would like to help Utah residents celebrate safely by reminding everyone of the potential for high concentrations of smoke associated with fireworks displays. This smoke is largely particulate matter (PM). In prior years, DAQ has monitored extremely high concentrations of both PM10 and PM2.5 (the fine and the very fine…
