Availability of Final Bi-National Report for the Great Lakes-St. Lawrence Seaway Study
The U.S. Army Corps of Engineers (USACE), Detroit District, is issuing this notice to announce the availability for public review and feedback of the final bi-national report for the Great LakesSt. Lawrence Seaway (GLSLS) Study. This study was conducted jointly with Canada and was overseen by a steering committee that included representatives from the United States Department of Transportation, Transport Canada, United States Fish and Wildlife Service, Environment Canada, the St. Lawrence Seaway Development Corporation, the United States Army Corps of Engineers, and the St. Lawrence Seaway Management Corporation. The study evaluated the commercial navigation infrastructure needs of the GLSLS as it is currently configured, and does not make any recommendations related to the implementation of any physical project modifications. The study assessed ongoing maintenance and long-term capital requirements to ensure the continuing viability of the system, targeting the engineering, economic and environmental implications of those needs as they pertain to the marine transportation infrastructure upon which commercial navigation depends. The public is invited to provide feedback which will be provided to the above noted partner agencies for their consideration as each assess the study findings related to future system's operation and maintenance.
Intent To Prepare a Draft Environmental Impact Statement for Proposed Dam Powerhouse Rehabilitations and Possible Operational Changes at the Wolf Creek, Center Hill, and Dale Hollow Dams, Kentucky and Tennessee
The Corps of Engineers (Corps), Nashville District, will prepare a Draft Environmental Impact Statement (DEIS) relating to proposed dam powerhouse rehabilitations and possible operational changes at the Wolf Creek, Center Hill, and Dale Hollow Dams in Kentucky and Tennessee. The Corps is studying the possible impacts of modifying existing equipment. Due to improvements in technology, rehabilitating the equipment could make it possible to produce more power from the same amount of water discharged. Changes in equipment and operational procedures could also cause higher tailwater heights and velocities, but as there is a limited amount of water they could be for shorter duration. In addition, alterations to flow regimes are being considered to provide minimum flows when hydropower releases are shut off. If improvements are successful, other dams may eventually be considered for similar changes. This study was begun in 2003 and a Notice of Intent was published in the Federal Register on September 25, 2003; however, due to funding constraints work ceased before a Draft EIS could be completed. The proposed rehabilitation of the powerhouse and generating units is not related to the dam seepage repairs that are ongoing at Center Hill and Wolf Creek Dams.
Intent To Prepare a Draft Supplemental Environmental Impact Statement (DSEIS) for the Nourishment of 25,000 feet of Beach in Topsail Beach, Pender County, NC
The U.S. Army Corps of Engineers (USACE), Wilmington District, Wilmington Regulatory Field Office has received a request for Department of the Army authorization, pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act, from the Town of Topsail Beach to conduct a one-time emergency beach fill project to protect oceanfront development and infrastructure until such time that a federally authorized shore protection project can be implemented. At this time, the construction date for the Federal project is uncertain. A Draft General Reevaluation Report Environmental Impact Statement (GRR-EIS) has been prepared by the USACE and was released for public review and comment in June 2006 (USACE, 2006). Given the current status of the GRR-EIS and the need for Congressional authorization, funding, preparation of plans and specifications, and right-of-way acquisition, the Federal project may not be implemented until Fiscal Year 2010, or possibly later.
