The project status for MBSD is now "Complete"


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 Environmental 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.

In April 2017, the Louisiana Trustee Implementation Group (LA TIG) of the Deepwater Horizon Natural Resource Damage Assessment Louisiana Restoration Area issued a notice that described its decision to support the development of a single MBSD EIS that can satisfy NEPA requirements for both the USACE and the LA TIG federal Trustees in potential restoration efforts in the Barataria Basin. This decision increased efficiency and reduced redundancy by avoiding development of two separate NEPA analyses for the same project. Federal and state member agencies of the LA TIG participated in the development of the DEIS as cooperating agencies. The LA TIG intends to rely on the DEIS to inform its decision under the Oil Pollution Act and to fulfill the requirements of the federal Trustees under NEPA. Following public review of the DEIS and completion of the Final EIS, the federal Trustees of the LA TIG expect to adopt the Final EIS by signature on a Record of Decision, which will document the LA TIG’s decision. The LA TIG's Draft Louisiana Phase 2 Restoration Plan 3.2 released in May 2021 is available here.

Agency Action Milestone Detail Details/Status Milestone Date
CPRA Bipartisan Budget Act of 2018 CPRA begins consultation with NMFS on marine mammal impact minimizing, monitoring, and evaluation.  

Following issuance of the MMPA waiver, the State will begin consultation with NMFS (using existing coordination processes to the extent possible) regarding practicable measures to minimize impacts to marine mammals, and measures to monitor and evaluate the impacts of the MBSD from construction, operation and maintenance. To date, the project sponsor has been in contact with NMFS about Phase I and Phase II marine mammal baseline data/monitoring.
