Planning Branch:
Division of Air Quality

The 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 the origins of the various contaminants detected in the air.

Computer Models

Computer Models 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.

Designated Facilities

Federal rules require that states prepare plans to reduce emissions from existing sources when New Source Performance Standards are issued for similar of sources of air pollution. The plans display how the existing sources will come into compliance, and assist the sources in understanding the requirements.

The four plans available now apply to:


Transportation Issues

The Planning Branch is also involved in identifying the air quality impacts of transportation issues which include vehicle inspection and maintenance, clean fuels, and highway construction. This information must be considered in the development of SIPs 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.
