The report documents an air quality modeling study of sulfur dioxide concentrations near March Point, Washington. The current study evaluated the measured data from these air quality monitors with predictions using the SHORTZ and ISCST air quality models. A series of 20 different test periods were used in the model evaluations. Neither model preformed well in a comparison of measured and predicted values when the data are paired in space and time. However, model prediction improved for both models when comparison was performed with the data paired in time, but not in space. The main conclusions were that air monitoring is not necessary, given the low level of impacts, and that neither model offers significant advantages unless terrain heights are higher than the stack heights, in which case the SHORTZ Model is preferred.
