The document provides general guidance on characterizing hazardous air pollutant releases and shows how to apply appropriate dispersion models. Specifically, it: Helps determine likely or reasonable storage conditions for specific chemicals for which a release might occur; Helps determine release classes (e.g., liquid or gaseous phase) of a hazardous release; Defines the steps to be taken when determining if a release should be considered a dense gas release (and thus require the use of a model capable of such a simulation); Defines the methods used to determine the input variables used by commonly-used refined models in the public domain; Points out the implications and effects of various choices for input information; Shows, by example, the calculation of the input variables used by the models; Describes the outputs available from the models; and Discusses how to determine the input that gives the 'worst-case' impact conditions.
