Take notice that the following hydroelectric application has been filed with the Commission and is available for public inspection.
k. Pursuant to Section 4.32(b)(7) of 18 CFR of the Commission's regulations, if any resource agency, Indian Tribe, or person believes that an additional scientific studyshould be conducted in order to form an adequate factual basis for a complete analysis of the application on its merit, the resource agency, Indian Tribe, or person must filea request for a study with the Commission not later than 60 days from the date of filing of the application, and serve a copy of the request on the applicant.
All documents may be filed electronically via the Internet. See 18 CFR 385.2001(a)(1)(iii) and the instructions on the Commission's Web site
m. The application is not ready for environmental analysis at this time.
n. The project would be located at an existing dam owned and operated by the Corps-St. Louis District. The existing Lake Shelbyville Dam was constructed in 1963 for the purposes of flood control, recreation development, water supply, navigation release, and fish and wildlife conservation. In August of 1970, the USACE closed the gates to start the initial filling of the lake. The West Okaw and Kaskaskia rivers were inundated 17 miles upstream of the dam.
The Lake Shelbyville Dam is an earthen embankment with an elevation of 643 feet above mean sea level (MSL). The dam is 3,025 feet long and rises 108 feet above the river bed. The concrete spillway is located at 593 feet MSL and is topped by three Tainter gates that are approximately 45 feet wide by 37 feet high. The two regulating outlet structures release water through the face of the spillway. The impoundment above the Lake Shelbyville Dam, referred to as Lake Shelbyville, varies according to flood control operations controlled by the Corps. Lake Shelbyville has a maximum storage capacity of 684,000 acre-feet. Of the 684,000 acre-feet of storage, 474,000 acre-feet have been designated for flood control.
The average depth of the reservoir is 16 feet and the maximum is 67 feet.
The proposed Lake Shelbyville Project would consist of: (1) A powerhouse located downstream on the western embankment of the spillway; (2) a penstock, which would be connected to the west outlet structure, and extend along the western bank to the powerhouse; (3) a trash rack with 4-inch spacing that would be integrated into the existing intake structure; (4) a new transformer pad located adjacent to the powerhouse; (5) a modified access road that would pass to the west of the powerhouse; (6) a parking lot on the west side of the powerhouse; (7) a 49-foot-long by 105-foot-wide tailrace; (8) 407 feet of 12.47-kilovolt (kV) buried transmission line to connect the project to the existing Shelby Electric Cooperative substation located 900 feet downstream of the dam; (9) three turbine-generator units for a combined installed capacity of 6.8 megawatts; and (10) appurtenant facilities. The projected annual energy generation would be 20.3 gigawatt hours.
The project would operate in a run-of-release mode utilizing releases from Lake Shelbyville as they are dictated by the Corps, with no proposed change to the Corps' facility operation. Power generation would be seasonally variable as flow regimens and pool levels are set forth by the Corps. The project would generate power using flows between 130 cfs (cubic feet per second) to 1,500 cfs. When flows are below 130 cfs, all flows would be passed through the existing outlet structure and the project would then be offline. When flows are greater than 1,500 cfs, excess flow would be passed through the existing outlet structure.
