REVIEW OF DEVELOPMENT AND APPLICATION OF CRSTER AND MPTER MODELS

The CRSTER and MPTER computer codes are two of many air quality disper sion models recommended for use in a regulatory context by the U.S. En vironmental Protection Agency. CRSTER and MPTER are generally applicab le to tall stack sources, such as coal-fired electrical utility power plants located in flat or gently rolling terrain. This paper briefly r eviews the developmental history, formulation, operation and applicati on of the CRSTER and MPTER models. Also reviewed are performance evalu ation studies which have included these two models. The paper conclude s with a brief discussion of future directions for regulatory modeling of tall stack sources.
