This manual presents guidance for designing, conducting, and evaluating air dispersion modeling analyses for Superfund sites. Its purpose is to provide a logical and systematic approach for applying air quality models, which are an integral part of several regulatory programs. Air dispersion models provide the ability to mathematically simulate atmospheric conditions and behavior and are used to calculate spatial and temporal fields of concentrations and particle deposition due to emissions from various sources. The output from air dispersion models is used to fill the gaps in data generated by air monitoring programs that cannot provide measured concentrations at all locations. Dispersion models can provide concentration or deposition estimates over an almost unlimited grid of user-specified locations, and can be used to evaluate both existing and forecasted emissions scenarios.
