This guide provides methods for determining expected pollution from an elevated point source of non-reactive pollutants. Concentrations are estimated using the Gaussian Bivariate Equation with solution by table look-up methods. Tables and equations are provided for determining plume rise based on the work of Briggs, for determining the wind velocity at physical stack height, the change of concentration for different averaging times, the expected maximum ground level concentration, and the distance to the expected maximum ground level concentration. The methods presented are especially well suited for hand held calculator solution. The guide is useful for engineers and scientists involved with environmental impact statement modeling.
