Rock Island District
Illinois Waterway and Upper Mississippi River
Description
The Dredged Material Management Program (DMMP) plays a crucial role in maintaining navigability of the Illinois Waterway and Mississippi River 9-Foot Navigation Channel. The Program takes a comprehensive approach to dredged material management by identifying and evaluating dredged material placement site(s) to accommodate the Corps’ dredging needs, integrating Engineering With Nature®, Regional Sediment Management, and beneficial use concepts. Planning efforts continue as sites along the Mississippi River and Illinois Waterway reach capacity. The Dredged Material Management Program ensures navigation vessels can safely transport commodities to ports within the United States and beyond.
Background
The Rock Island District has been developing plans and acquiring and implementing sites for the long-term placement of channel maintenance dredged material since the completion of GREAT II (Great River Environmental Action Team) studies in 1980. Dredged Material Management Plans use a six-step planning process, and Federal Standard evaluation criteria: dredging cost and operational feasibility; environmental acceptability - natural, aesthetic, cultural resources; beneficial use of dredged material, and social impacts.
DMMP activities typically require coordination with the following agencies:
- U.S. Coast Guard Eighth District - New Orleans, Louisiana
- U.S. Environmental Protection Agency, Region V - Chicago, Illinois
- U.S. Environmental Protection Agency, Region VII - Kansas City, Missouri
- U.S. Department of the Interior, Fish and Wildlife Service - Rock Island, Illinois
- Illinois Environmental Protection Agency - Springfield, Illinois
- Illinois Department of Natural Resources - Springfield, Illinois
- Iowa Department of Natural Resources - Des Moines, Iowa
- Missouri Department of Natural Resources - Jefferson City, Missouri
- Wisconsin Department of Natural Resources - La Crosse, Wisconsin
Status
The Rock Island District prepares and implements Dredged Material Management Plans for the Mississippi and Illinois Waterway 9-Foot Navigation Channel. The district also purchases and constructs dredged material placement sites to provide capacity for operation and maintenance dredging.
The program ensures that all practicable and reasonable alternatives for the placement of dredged material are fully considered on an equal basis. This includes the placement of dredged material in the least costly manner, operationally feasible, and with sound engineering and environmental requirements. Additionally, the District continues to pursue beneficial use opportunities with partners and stakeholders.
