This book was released on 1979 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

BOX 1027DETROIT, MICHIGAN A8231.TELEPHONE: (313) 226-6752 1. NAME OF ACTION: (X) ADMINISTRATIVE ( ) LEGISLATIVE 2. , DESCRIPTION OF ACTION: Maintenance dredging of'Monroe Harbor,Michigan is normally performed annually during Aptil and Mayfor a period of about 1 1/2 months. Approximately 230,000 cubic yards of sediments will be dredged annually for the next 3-5 years until the area la filled. Once the site is filled, no further dredging will be done until another suitable disposal site is found and an environmental ' impact statement is prepared on the confined disposal site discharge location. This material has been classified as polluted and will be placed in a confined disposal facility to prevent the re-entry of contaminants into the aquatic system. The matetial is removed from a navigation channel and turning basin that ib approximately 5.5 miles in length; extending from the 21-foot water depth in Lake Erie to a point about 1.6 miles upstream of the mouth of the River Raisin. The disposal site is a AO acre diked area owned by the Detroit Edison Power Company located at the mouth of the River Raisin. 3. (A) ENVIRONMENTAL IMPACTS: The harbor dredging action will temporarily degrade water quality. The disposal of the polluted material into the confined disposal facility will convert the nowponded, former lake-shoal area Into a terrestrial environment. Commercial navigation requires maintenance dredging of the channel and harbor area for Immediate continued use. The proposed actions would: (1)-render a partial pollution abatementfunction through the removal of polluted sedime

This book was released on 1975 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed project is to perform maintenance dredging of the Saginaw River and Saginaw Bay Federal Navigation channels. Dredging will be performed by a Government-owned hopper dredge. Approximately 140,000 cubic yards of polluted material dredged from the river, from the Detroit and Mackinac Railroad Bridge to the upper limits of the harbor, is placed on the confined disposal area on Middle Ground Island. The polluted channel section from the D & M R.R. bridge to the river mouth and the section throughout the inner bay will not be dredged until a confined disposal site is constructed to contain this dredged material. The average annual volume of shoaling throughout the project is approximately 840,000 cubic yards. (Author).

This book was released on 1976 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resumption of the removal of polluted material will temporarily degrade the water quality and localized turbid problems are anticipated to be encountered at areas during removal of the rocky material. Disposal of the dredged material into their respective disposal sites may affect the aquatic ecosystem. Continued economic and social stability of the Great Lakes is dependent upon commercial navigation which requires maintenance dredging of the connecting channels of the Detroit River. Short-term increased turbidity and temporary water quality degradation in the area of operation are effects of maintenance dredging. Aquatic life in the dredging areas will be disturbed or destroyed. Disposal of the dredged sediments will alter existing habitats and may otherwise adversely affect organisms at the disposal areas. Dredging alternatives include: (1) alternative dredge types; (2) discontinue maintenance dredging completely; (3) dredge the connecting channels to a lesser depth; and (4) wastewater management. Implementation of the alternatives will cause economic or social impacts on the Detroit River area as well as the Great Lakes region. Alternatives to the disposal methods are examined. In terms of economic and engineering feasibility, irretrievable resources and minimal ecological disruption, the process of confined disposal of polluted materials and open water disposal for non-polluted sediments offers the best alternatives at present.

This book was released on 1980 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This statement addresses the Operation and Maintenance of the Crooked River portion of the Inland Route, Michigan, including dredging, dredge material disposal, and the continued operation and maintenance of the Crooker River lock and weir at Alanson, Michigan. Since an upland disposal site would be used, a transfer facility would also be required. Dredged material removed from the Crooked River would be transferred to trucks at the foot of Snider Road at the Crooked River, and hauled to the disposal site, located approximately one (1) mile north on Snider Road. The estimated annual shoaling rate in Crooked River is 1,000 cubic yards, and the river will require about 9,500 cubic yards of backlog dredging. Thus, the total capacity of the site for 10 years is 19,500 cubic yards. Maintenance dredging is necessary to restore the waterway's ability to accommodate recreational craft navigation. The proposed Federal action also includes operation and structural maintenance of the lock and weir on the Crooked River at Alanson. Structural maintenance and operations are required to insure continuance of vessel passage along the Inland Route. Water level regulation of the upstream rivers and lakes is a function of the lock facilities. Additionally included in the action is the proposed construction of public use facilities at the lock. The plan provides for the construction of a parking lot, restroom facilities, storage building, observation platform and docking area, and landscaping. (Author).

This book was released on 1976 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed action is to perform maintenance dredging of the St. Clair River when required to remove shoaling. Average annual volume removed is approximately 130,000 cubic yards consisting primarily of gravel, sand, and silt. The material removed will be disposed of deep water or placed on selected onshore sites. All materials scheduled for removal from the St. Clair River have been classified by the U.S. Environmental Protection Agency as suitable for unrestricted open water disposal. Most maintenance operations are accomplished by hopper dredge, but a derrickboat utilizing a bucket dredge removes channel obstructions if rock rather than sand or silt must be removed. The open water disposal sites used by the hopper dredge are located in the deep water of Lake Huron several miles north of the Blue Water Bridge and during 1976 in deep water of the North Channel adjacent to Point Au Chenes. The use of the North Channel disposal area will be discontinued after the 1976 work season. In subsequent years sediments removed from the lower reaches of the river will be stockpiled at an onshore site furnished by the Michigan Department of Natural Resources for future project was uses in maintenance and further development of the St. Clair Flats Wildlife Area.
