Abstract : The proposed action is the construction of a confined disposal facility for contaminated dredged materials and maintenance dredging of the Les Cheneaux Island channels. The dredged materials disposal facility would be located inland, approximately two miles by road from the new Village of Cedarville Marina. The facility would have a capacity of 110,000 cubic yards. This would contain a ten year maintenance quantity of 40,000 cubic yards, plus 70,000 cubic yards of backlog. In addition, maintenance dredging would include another 18,000 cubic yards of bottom material suitable for open lake disposal. A total of 128,000 cubic yards would be dredged. The channels to be maintained are approximately 40,000 feet in length and have previously been deepened to 7 feet and widened to 100 feet with additional enlargement where required. Maintenance dredging is necessary for continued recreational use of the channels.
