The project status for MBSD is now "In Progress"


On June 22, 2016, CPRA submitted a joint permit application which included a brief project description:

"The Mid-Barataria Sediment Diversion is a large scale, complex civil works and ecosystem restoration project. When operated, up to 75,000 cubic feet per second (cfs) of sediment laden water would be diverted from the Mississippi River to the mid-Barataria Basin to reconnect and re-establish the natural or deltaic sediment deposition process between the Mississippi River and the Barataria Basin to deliver sediment, freshwater, and nutrients to reduce land loss and sustain wetlands."

The proposed MBSD project has the potential for significant impacts and requires an Environmental Impact Statement (EIS) under the National Envrionmental Policy Act (NEPA) to inform a permit decision relative to the lead federal agency under Section 404 of the Clean Water Act (Section 404) and Section 10 of the Rivers and Harbors Act (Section 10), and permissions under Section 14 of the Rivers and Harbors Act (Section 408) The USACE-MVN Regulatory permit processing number is MVN-2012-2806-E00.
