The Federal Energy Regulatory Commission on Feb. 11 issued a notice and an explanation of the planned environmental review process on a July 2013 original major license application for a 48-MW hydroelectric project in Alabama.
Birch Power Co. is seeking a license on the Demopolis Lock and Dam Hydroelectric Project, locate at the U.S. Army Corps of Engineers’ Demopolis Lock and Dam on the Tombigbee River, west of the city of Demopolis in Marengo and Sumter counties, Alabama.
The applicant contact is: Nicholas E. Josten, GeoSense, 2742 Saint Charles Ave, Idaho Falls, ID 83404, (208) 528-6152.
The proposed project would consist of these new facilities: a 900-foot-long excavated intake channel (headrace); two 60-foot-long by 32-foot-wide trash racks with 2.5-inch bar spacing; a 201-foot-long by 80-foot-wide powerhouse containing two 24-MW Kaplan turbines, having a total installed capacity of 48 MW; a substation; a forebay oxygen diffuser line system to enhance dissolved oxygen; a 1,880-foot-long excavated tailrace channel; a 1,700-foot-long retaining wall along the north side of tailrace channel; and a 4.4-mile-long, 115-kV transmission line. The average annual generation would be about 213,000 megawatt hours.
The commission intends to prepare an environmental assessment (EA) on the project. FERC staff will conduct one local agency scoping meeting and one local public meeting on March 26 as they take input on what should be in that EA.
