The Federal Energy Regulatory Commission’s Office of Energy Projects on June 13 issued a final environmental assessment report related to an original license application for the proposed 5.25-MW Braddock Locks and Dam Hydroelectric Project.
This project would be located on the U.S. Army Corps of Engineers’ Braddock Locks and Dam facility on the Monongahela River in the Borough of West Mifflin and the City of Duquesne in Allegheny County, Pa. The final EA concludes that issuing a license for the project, with appropriate environmental measures, would not constitute a major federal action significantly affecting the quality of the human environment.
In September 2012, Lock+ Hydro Friends Fund XLII LLC filed this application for an original license. The Corps’ Braddock Locks and Dam is one of nine navigational structures, collectively known as the Monongahela River Locks and Dams system, which provide year-round navigation on the Monongahela River between Pittsburgh, Pa., and Fairmont, W.Va.
The Braddock Locks and Dam is located at river mile 11.2. The lock chambers and operations buildings are situated along the right bank of the river adjacent to a major steel-making plant.
Hydro Friends proposes to construct: a powerhouse with seven turbine-generators at the left closure weir on the south side of the existing Braddock Locks and Dam, having a total installed capacity of 5.25 MW; a 0.45-mile-long, 23-kV transmission line; and a switchyard and control room. The project’s average annual generation is expected to be 32,263 megawatt-hours (MWh).
