Air Dispersion Modeling Guidelines for Arizona Air Quality Permits

This guidance document has been developed by the Air Quality Division (AQD) of the Arizona Department of Environmental Quality (ADEQ) to document air quality modeling procedures for air quality permit applications for sources located in Arizona under ADEQ jurisdiction. This guidance provides assistance to the Permittee required to perform modeling analyses to demonstrate that the air quality impacts from new and existing sources protect public health, general welfare, physical property, and the natural environment.
