| Abstract: | The Upper Ohio Navigation Study, PA (UONS), is a feasibility-level study to identify the best long-term plan for maintaining safe, reliable, efficient, and sustainable navigation on the Upper Ohio River through the analysis period of 2025 - 2074. The study addresses Emsworth, Dashields, and Montgomery Locks and Dams (collectively EDM), originally completed in 1922 to 1936. These facilities provide navigable conditions on the first 31.7 miles of the 981-mile Ohio River and are central in position to the Port of Pittsburgh and the U.S. Army Corps of Engineers Pittsburgh District’s 23 locks and dams on the Allegheny, Monongahela, and Upper Ohio rivers. The Study’s feasibility report and integrated environmental impact statement document the formulation and evaluation of plans that address the critical structural condition of the lock walls, lock capacity issues, and ecosystem needs in the study area. The report recommends for Congressional authorization the construction of one new lock at each facility. This recommended plan is justified as the National Economic Development (NED) Plan, and is consistent with protection of the environment. The new lock chambers will be the same size as the original main chambers (110’ wide by 600’ long), and will be constructed in the footprint of the original auxiliary chambers. The original main chambers will continue to operate during construction and then be retained and maintained with a “reactive maintenance” policy. |
