Abstract
Electric utilities need the capability to reliably simulate the ambient impact of power plant emissions in order to meet corporate environmental objectives and support regulatory permit applications. Current regulatory models tend towards conservatism in their calculations (i.e., overpredict actual concentrations) to compensate for modeling and input data uncertainties. The scientific bases of the plume rise and building downwash routines of existing regulatory dispersion models are of particular concern since they are based on rather sparse sets of wind tunnel observations. These models also suffer from multiple discontinuities in their treatment of stack height—a vestige of their evolution by super-imposition of independently-derived downwash algorithms (Corio, 1990).
