Air Quality Modeling

Air quality modeling is used to predict air quality concentrations and is used in lieu of air quality monitoring for permitting. Although air quality modeling is used in other ways, for example compliance, this website has been designed to supply information for people completing air quality modeling for new source or existing source permitting. DNR completes two distinctly different types of air quality modeling: stationary source and indirect source.

Stationary Source

Stationary source air quality modeling is used to determine whether air quality standards are met for new and existing source permitting.
