The purpose of the project was to identify and define the computation requirements or estimating the air impacts from the remediation of Superfund sites. Two example sites employing soil excavation were selected because they represent a complex emission source. The procedures for the evaluation of the ambient impacts were divided into several subtasks. These included site characterization, selection of remedial alternatives, definition of remedial activities, estimation of emission rates for each remedial activity, determination of ambient concentrations fromdispersion modeling, and evaluation of carcinogenic and noncarcinogenic risks based on dispersion modeling results. The calculation of emission rates were used to estimate ambient impacts through dispersion models. The purpose was to outline a set of procedures that could be used, with existing tools, to assist in the evaluation of air-pathway effects.
