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.

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 …
Read MoreAir 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 …

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 …

Air Quality Modeling Program
What Is An Air Pollution Model? A computer model simulates the meteorological conditions and chemical reactions that chemical govern air pollution formation and transport. Why Do We Need Air Pollution Models? Pollution is formed when gaseous emissions from cars, industry, and residential sources react in the air to form particulate pollution in the winter and …

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 …

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 …

Exceptional Events Program
In dry areas like Utah, windblown dust maybe 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 in the air. Much of this PM is small enough to be …
Read MoreStatewide Emissions Inventories
The following links contain inventories developed for statewide criteria and hazardous air pollutants. If comparing inventories, the reader should note that emission estimation methods and emission factors are continually changing and improving, which may cause emissions to appear higher or lower from one year to the next without any actual emission change. In addition, the …

Statewide Emissions Inventories
The annual emissions inventory is one means used by the State to assess the level of pollutants released into the air from various sources. A group of common air pollutants regulated by the Environmental Protection Agency (EPA) are called criteria air pollutants; these pollutants were determined based on their health and/or environmental effects. The second …
