Abstract
Reliable estimates of maximum 3-hour and 24-hour SO2 concentrations due to power plant emissions are required for a variety of environmental assessment activities associated with air quality maintenance planning, fuel switching, plant siting and tall stack policy evaluations. Either of two methods are generally employed for the prediction of maximum SO2 concentrations for these two averaging times. The purpose of the present study was to examine the effect upon ratio distribution statistics if only peak concentrations above a certain cutoff value were analyzed. This report describes the plant site characteristics and the meteorological and air quality data bases used in the study. This will be followed by a discussion of the ratio distributions and their associated statistics, including an analysis of the variation of these parameters for different plant sites and peak concentration cutoffs. The report concludes with a discussion regarding the general applicability of these results to other point sources.
