Utah Point Source Halogen Emissions
HB 220 – Emissions Reduction Amendments, was passed during the 2023 Utah Legislature General Session. The legislation was subsequently signed into law by Governor Cox. The legislation’s applicability is limited to Box Elder, Davis, Salt Lake, Weber, Tooele and Utah counties and directs the Utah Division of Air Quality (DAQ) to: The legislation also directs…

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
Utah Division of Air Quality 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…

Air Quality Exceptional Events Program
Air quality 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…

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…

Windblown Dust: Exceptional Events Program
In dry areas like Utah, windblown dust may be a significant air pollution problem. From spring through fall, unusually high winds can combine with dry surface conditions to result in dust storms. These dust storms can lead to extremely high levels of particulate matter (PM) in the air. Much of this PM is small enough…

Planning Branch: Division of Air Quality
The Air Quality Planning Branch is responsible for developing comprehensive plans (also known as State Implementation Plans (SIPs)) to reduce air pollution, and developing rules that set requirements on air emissions for both individuals and industry in Utah. The planning Branch is composed of three sections: Emissions Inventories Emissions Inventories are routinely compiled to understand…

Sections: State Implementation Plan (SIP)
The Clean Air Act (CAA) of 1970 required the creation of National Ambient Air Quality Standards (NAAQS) to protect both public health and the environment. To meet this requirement, the U.S. Environmental Protection Agency (EPA) set air quality standards for seven pollutants: total suspended particulates, sulfur dioxide, carbon monoxide, hydrocarbons, ozone, nitrogen dioxide, and lead.…
