Abstract
Comments on Hening Huang et al.'s use of probabilistic method to analyze ocean outfall mixing zones are presented. Based on probabilistic technique, Huang et al. proposed that the exceedance probability use to delineate mixing zone boundary be 0.0037 to meet EPA criterion that the four-day averaged concentration must not exceed the water quality standard more than once every three years. However, it shows that the exceedance probability should be equal to 0.0044 to meet state and EPA regulatory requirement.
