Construction for a new lock on the Monongahela River

Pennsylvania Projects

Pittsburgh District geotechnical engineers and geologists study subsurface terrain to assess bedrock for construction projects. A marine drilling crew has been working at Emsworth Locks and Dams since July to drill more than 50 boreholes. The geotechnical team will send samples to a lab to identify the bedrock hardness, strength and permeability for construction. The district plans on constructing a newer, larger lock chamber at Emsworth as part of the Upper Ohio Navigation Project.

In January 2002, Section 8143 of Public Law 107-117 directed the U.S. Army Corps of Engineers to cleanup radioactive waste at the Parks Township Shallow Land Disposal Area (SLDA) site under the Formerly Utilized Sites Remedial Action Program (FUSRAP). The cleanup will follow the remediation process outlined in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and is consistent with the requirements of the July 5, 2001 Memorandum of Understanding between the U.S. Nuclear Regulatory Commission and the U.S. Army Corps of Engineers for coordination of cleanup and decommissioning of FUSRAP sites with NRC-licensed facilities.

The Kinzua Dam releases 15,000 cubic feet of water per second for eight hours, resulting in 3.2 billion gallons of water released into the river during those hours, equivalent to nearly 5,000 Olympic-sized swimming pools in Warren, Pennsylvania, March 30, 2023. Kinzua Dam released this water in March to simulate a “spring pulse,” which are natural phenomena that typically occur in temperate climates and during early spring and send cues to aquatic species and other parts of the ecosystem by moving sediments and nutrients. The district’s water management team modeled the operation to ensure the artificial pulse would not impact the reservoir’s summer pool or cause flooding.

FUSRAP Projects

Under the Formerly Utilized Sites Remedial Action Program (FUSRAP), the U.S. Army Corps of Engineers (USACE) is cleaning up sites with contamination resulting from the Nation’s early atomic energy program. FUSRAP was initiated in 1974 to identify, investigate and, if necessary, clean up or control sites throughout the United States contaminated as a result of Manhattan Engineer District (MED) or early Atomic Energy Commission (AEC) activities. Both the MED and the AEC were predecessors of the U.S. Department of Energy (DOE).

Congress transferred administration and execution of FUSRAP cleanups from the DOE to USACE in October 1997. USACE continues to address sites the DOE began, sites that were referred to USACE by the DOE Office of Legacy Management under a USACE/DOE Memorandum of Understanding, and one site added to the program by Congress.

Mega Projects

Mega projects are critical projects within the Corps of Engineers' portfolio that may have high investment costs, critical schedule requirements, are unique from a design/construction/procurement perspective, or have a higher level of national significance.

Flood Risk-Reduction Projects

Flood risk is a combination of the likelihood of a natural or man-made flood hazard happening and the consequences or impact if it occurred. Flood-risk management (FRM) is one of USACE Civil Works' three core missions, alongside support for commercial navigation and restoration of aquatic ecosystems. USACE’s FRM activities seek to reduce the threat to life and property from riverine and coastal storm flooding through the development and communication of advanced knowledge, technology, and solutions.

Reservoir Master Plans

Master plans affect the management and use of government-owned and leased lands around reservoirs and other corps-operated structures. U.S. Army Corps of Engineers regulations require master plans to be periodically reviewed to ensure they meet current public and environmental needs.
