Refined air toxics models are increasingly being used to assess the impact of toxic air pollutants released into the atmosphere. The purpose of the guidance document is to provide general guidance considerations for applying dispersion models to such releases and to show the thought process required by the non-expert user to develop all model input parameters. Two example applications for each model are provided with a step-by-step explanation of all model input parameters and model output. Four specific models are currently included in the document. These are the DEGADIS, HEGADAS, and SLAB models appropriate for denser-than-air releases and the AFTOX model for neutrally buoyant releases of toxic air pollutants.
