Lower Monongahela River Project

Locks and Dams 2, 3 and 4 on the Monongahela River in Allegheny, Washington and Westmoreland counties in southwestern Pennsylvania are the three oldest currently operating-navigation facilities on the Monongahela River. These locks experience the highest volume of commercial traffic on the entire Monongahela River Navigation System and the pools created by these facilities provide industrial and municipal water, and are popular with recreational boaters.

Shallow Land Disposal Area

The Shallow Land Disposal Area (SLDA) site, encompassing 44 acres of privately-owned land, is located approximately 23 miles east-northeast of Pittsburgh in Armstrong County, Pennsylvania. It is on the right bank of the Kiski River, a tributary of the Allegheny River, near the communities of Apollo and Vandergrift. Radioactive waste disposal operations were conducted between 1960 and 1970 at the site.

Upper Ohio River Navigation Project

The Upper Ohio Navigation Project is part of the National Economic Development (NED) plan for improving the upper Ohio River navigation system, specifically the Emsworth, Dashields and Montgomery locks and dams. Emsworth, Dashields and Montgomery, each constructed prior to 1936, are the first three locks and dams on the Ohio River downstream of the Point of Pittsburgh. These facilities have the oldest and smallest lock chambers in the entire Ohio River Navigation System. The project replaces each auxiliary lock chamber (56’ wide by 360’ long) with a new lock chamber (110’ by 600’) at each facility. This new lock chamber would serve as the new main lock chamber. The fully-funded, total project cost for all three new chambers is $2.1 billion, which would be cost-shared jointly by the General Fund (65%) and the Inland Waterways Trust Fund (35%) (2021 Cost Level). The project’s incremental benefit-to-cost ratio is 2.4 to 1 (at the current discount rate of 2.75%).
