new harbor as been constructing in Gadukdo. However, a lot of fugitive dust gas been often generated from construction site reclaiming sea sand, especially when the Northwester is blown strongly. It has resulted insome appeals of residents in Gadukdo. In this study, we estimated the amount of fugitive dust caused by new harbor construction using Fugitive dust formula. Also, the concentration of PM10 for recipient is predicted by AERMOD. The amount of fugitive dust is 26.56 ㎍/secㆍ㎡ and 11.84 ㎍/secㆍ㎡ respectively by the Fugitive dust formula. PM10 outlet concentration and the amount of fugitive dust increase according to wind velocity and directions. AERMOD is performed on the basis of weather data and the amount of fugitive dust generated with wind velocity. As a result of AERMOD, the PM10 concentration of Sunchang and Oinul are predicted over 100 ㎍/㎥. The PM10 concentration of Sunchang and Oinul are predicted over 130 ㎍/㎥ when wind velocity of northwester in winter is over 11 m/s (Air Quality for Particulate Matter (100 ㎍/㎥ for 24 hours)). Also, the measured error between AERMOD and actual measurement is lower than 5%.
