| Abstract |
The report presents an analysis of SO2 time concentration relationships in the vicinity of a power plant and a validation of the EPA Single Source model using concentration and meteorological data collected in the same area. The concentration relationships studied were peak 1-hour to average 3-hour and peak 1 hour to average 24-hour concentration ratio distributions and the effect upon the statistics of these distributions of variables such as wind speed, atmospheric stability, hour of the day, and peak 1-hour concentration itself. The principal finding of the validation exercise was that the model underpredicted SO2 concentrations for all 4 receptor locations in the study area. The agreement between measured and calculated concentrations was not noticeably improved by the use of more accurate and detailed emissions and meteorological data bases. |
