A) Modeling of air emissions The air pollutants of interest in this project are PM 10. The main sources are emissions during mining and transportation. Dust emission is not significant in dredge mining as the ore and rejects are in wet or slurry form. Road transportation of ore on the haul road is the only source of dust emission.
