Prediction of air quality impacts for stack emissions from the proposed Vienna unit No. 9
Predictions of air pollution concentrations were made using the standard Gaussian plume model with a combination of the Briggs A and Pasquill-Gifford-Turnber B-F dispersion parameters; stability class as determined from Turner's algorithm was modified by shifting to the next more unstable class. Briggs's formulas were used to compute plume rise and inversion layer penetration. Downwash and building wake effects were treated by the EPA recommended approach modified to account for initial plume dilution. Ten years of meteorological data were used as model input; this data base was derived from surface measurements at Salisbury, MD., and rawinsonde data taken at Wallops Island, Virginia. The predicted concentrations were compared with applicable air quality standards.
