This environmental impact statement is concerned with the dredging of about 24,800 cubic yards of sediment from the Vermilion Harbor area approximately once every three years and maintenance of existing harbor structures. Harbor dredgings suitable for open-lake disposal will be deposited in a designated open-lake site in Lake Erie. Dredgings not suitable for open-lake disposal will be transported approximately 10 miles to Huron Harbor, Ohio, and deposited in a diked disposal area. It is estimated that for each maintenance operation an average of 20,000 cubic yards will be suitable for open-lake disposal and 4,800 cubic yards will require containment. Such dredging will result in continued safe navigation in the harbor for recreational craft and commercial fishing vessels continued participation in harbor related outdoor recreation continued growth potential for water-related commerce in the Vermilion area and temporary disturbance of manmade facilities within the harbor and lagoons areas. Adverse environmental impacts include disturbance and benthic communities within the dredged channels and in the open-lake disposal areas temporary resuspension of potentially harmful substances and increased turbidity levels during maintenance procedures temporary disturbance of fish populations and temporary interference and the generation of noise, odors and dust and air pollutants due to the presence of maintenance plant.
