Maintaining economic viability in the rapidly developing global marketplace is a major priority of ports nationwide It is imperative that commercial ports, such as those in New York NY and New Jersey NJ, evolve to remain competitive with developing global infrastructure. As a consequence, the U.S. Army Engineer District, New York, and the Port Authority of New York and New Jersey are going forward with plans to deepen existing channels for use by the newest generation of container ships. This will include the deepening of several waterways, most prominently the Kill van Kull KVK, Arthur Kill AK, and Port Jersey Channel, to a depth of 50 ft. A significant by-product of each deepening project will be large amounts of dredged material. In the case of the KVK and AK, the material will be composed predominantly of bedrock. As a result, the U.S. Army Corps of Engineers has commissioned a series of investigations into the viability of beneficially using dredged bedrock in the NYNJ Harbor. This report outlines how numerous beneficial use opportunities can become feasible based on bedrock characteristics, case-specific constraints, and applicable regulatory concerns. Beneficial uses of bedrock are promoted by legislative acts. A few uses have been practiced routinely in this region. This report seeks to highlight considerations toward broader uses of bedrock commensurate with projected dredging volumes. This report does not seek to compare the relative merit or cost differential between viable beneficial use opportunities. Information regarding the method for determining the feasibility assessments is detailed.
