Air dispersion modeling is a practice of using mathematical equations to characterize the atmospheric conditions and address how pollutants emitted by a source disperse. Dispersion models require detailed inputs in order to produce meaningful predictions. Modeled predictions provide useful information in making decisions for permits, state implementation plans, and even air monitor siting.
The Air Dispersion Modeling Section works to adhere to modeling guidelines set forth by the U.S. EPA while working with sources and permit writers to obtain precise source details in order to produce results that accurately characterize the atmospheric conditions. Air dispersion modeling is just one way to demonstrate compliance and to ensure that human health and the environment remain protected through the achievement and maintenance of acceptable air quality.
