Summary of Available Guidance and Best Practices for Determining Suitability of Dredged Material for Beneficial Uses

Abstract : The Corps of Engineers has the responsibility to maintain navigation of waterways across the United States. The Corps dredges more than 300 million cubic yards of sediment annually. Subsequently, methods to evaluate and determine environmentally and economically sound management alternatives are needed. Technological advances in equipment, treatment, and handling technologies continue to increase the options for beneficial uses (BUs). Ten categories of BU are: 1) Habitat development, 2) Beach nourishment, 3) Aquaculture, 4) Parks and recreation, 5) Agriculture, forestry, and horticulture, 6) Strip mine reclamation and solid waste management, 7) Shoreline stabilization and erosion control, 8) Construction and industrial use, 9) Material transfer, and 10) Multiple purpose. BUs of dredged material have a productive history resulting in over 2,000 man-made islands, more than 100 marshes, and nearly 1,000 habitat development projects. Corps islands provide vital habitat for rare, threatened, or endangered species. It is estimated that 1,000,000 birds nest on dredged material islands each year. BUs of existing dredged material in confined disposal facilities (CDF) should be considered along with all the alternatives available for CDF management. This report compiles current guidance and best practices useful to evaluate dredged material from ongoing dredging projects or CDFs for BUs.
