Summary
Abstract: (Summary adapted from EPA.)

AFTOX (Air Force Toxics Model) a Gaussian dispersion model that will handle
continuous or instantaneous liquid or gas elevated or surface releases from
point or area sources. Output consists of concentration contour plots,
concentration at a specified location, and maximum concentration at a given
elevation and time.

Description: Dispersion modeling uses mathematical formulations to characterize the
atmospheric processes that disperse a pollutant emitted by a source. Based on
emissions and meteorological inputs, a dispersion model can be used to predict
concentrations at selected downwind receptor locations. These air quality
models are used to determine compliance with National Ambient Air Quality
Standards (NAAQS), and other regulatory requirements such as New Source Review
(NSR) and Prevention of Significant Deterioration (PSD) regulations. These
models are addressed in Appendix A of EPA's Guideline on Air Quality Models
(also published as Appendix W of 40 CFR Part 51), which was originally
published in April 1978 to provide consistency and equity in the use of
modeling within the U.S. air quality management system. These guidelines are
periodically revised to ensure that new model developments or expanded
regulatory requirements are incorporated.
