STACK GAS EMISSIONS FROM OCEANGOING SHIPS: A DIFFUSION STUDY FOR THE PORT OF GALVESTON

A mathematical diffusion study was performed for the port of Galveston to determine the effect of ship stack gas emissions on ambient air quality. The Gaussian distribution equation, the Holland stack rise equation, the EPA Air Quality Display Model (modified), and input data from actual and theoretical conditions were used in the study. The results of the study are isopleths for particulate, carbon monoxide, sulfur dioxide, Nitrogen Oxides (NOx), and hydrocaborn emissions. Additionally, data are provided on the maximum ground level concentrations of each of the above pollutants. A comparison of these data with Federal Ambient Air Quality Standards shows that sulfur dioxide emissions from the use of 2.5% sulfur in the fuel slightly exceed the secondary standard.
