CHALLENGES TO BENEFICIAL USE Why is it so difficult to use dredged material beneficially?

1. CHALLENGES TO BENEFICIAL USEWhy is it so difficult to use dredged material beneficially? VESSEL TRAFFIC SAFETY: Safety is of paramount importance to everyone. Types of Dredges used/Location of Areas for BU/Manner of Operation of Equipment All has potential for impacts to vessel traffic safety. NEED FOR CERTAIN DREDGE EQUIPMENT OR AVAILABIITY OF SUCH EQUIPMENT: On the Lower Mississippi River COE’s Need for Hopper Dredges Hopper Dredges are not as conducive to BU as Cutterhead or Superdust pan dredges. Frequently alternative equipment such as a suitable hydraulic dredge is not available at the time the project needs to be undertaken. SUITABILITY OF DREDGED MATERIAL: Occasionally the material being dredged is too fine, coarse, contaminated, or otherwise not suitable for beneficial use. LACK OF OPPORTUNITY: There are sometimes simply no feasible locations to use dredged material beneficially. Low Quality BU/High Cost High Quality BU/No Source or Small Source in Close Proximity COST/FUNDING: Most often the cost for BU is greater. Federal Standard/Base Plan. Federal funding/State funding/Shared funding
