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. Emissions inventories are routinely compiled in order to understand the origins of the various contaminants detected in the air. 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. The 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 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. The planning branch is comprised of three sections: Mobile Sources, SIP/Rules and Technical Analysis.
