  1. Beneficial Use of Dredged Material: A Partnership for Coastal Louisiana Bren Haase Louisiana Department of Natural Resources Presentation to the Coastal Protection and Restoration Authority 23 April 2008

  2. Outline • What is beneficial use? • Nationwide • Louisiana • Why is it important? • Sediment source • What are we doing about it? • Programs involved • CWPPRA • LCA • CAP • CIAP • Surplus Funds • Near term/Long Term • Permitting

  3. What is beneficial use? • Utilizing dredged sediments as resource materials in productive ways Nationally • Engineered uses – beach nourishment • Agricultural and product – replace topsoil, industrial fill • Environmental enhancement – habitat restoration Louisiana • Coastal restoration and protection

  4. Why is it important? Most readily available source of sediment come from maintenance dredging for navigation projects: • Largest maintenance dredging program nationwide • 10 navigation channels/2800 miles of waterways • 70 to 90 million cubic yards annually • It’s being dredged anyway

  5. New Orleans District’s Major Navigational Channels Mississippi River GIWW Baptiste Collette GIWW Calcasieu Freshwater Mermentau South Pass Barataria Atchafalaya Fourchon Houma Tiger Pass Southwest Pass

  6. Why is it important? There is reasonable potential to use about 45 million cubic yards beneficially every year = 10 square miles marsh/year

  7. What are we doing about it? Partner in cost-shared projects • Continuing Authorities Program – 11 projects • CWPPRA – 2 projects • Louisiana Coastal Area, Beneficial Use – $100 M Partner with contributed funds • Coastal Impact Assistance Program – $23 M • Surplus Budget Funds – 2 projects • Oyster Lease Acquisition and Compensation Program (OLACP)

  9. Challenges • Logistics • Commitment to navigation interest • Sediment characteristics • Environmental windows • Lack of funds for disposal facility construction • Sea conditions • Federal standard • The dredged material disposal alternative or alternatives identified by the Corps which represent the least costly alternative(s) consistent with sound engineering practices and meeting the environmental standards established by the 404 (b) (1) evaluation process or ocean dumping criteria 33 CFR Parts 209, 335-338

  10. What are we doing about it? • Beneficial Use Summit, March 14, 2008 • Interagency Beneficial Use Work Group • Identify short term partnering opportunities • 10 sites identified and prioritized • Corps policy - disposal site containment (PGL 47) • OLACP Long term Goal: beneficial use projects on the shelf and ready to be built
