Coastal restoration, beach nourishment, and levee reconstruction are crucial to mitigate future coastal erosion, land loss, flooding, and storm damage in the Gulf of Mexico. The success of that long-term effort depends on locating and securing significant quantities of OCS sediment resources that are compatible with the target environments being restored.
Offshore sand resources, like upland sources, are extremely scarce where most needed. Additionally, vast areas of these relatively small offshore sand resources are not extractable because of the presence of oil and gas infrastructure, archaeologically sensitive areas, and biologically sensitive areas. BOEM is implementing several measures to help safeguard the most significant OCS sediment resources, reduce multiple use conflicts, and minimize interference with oil and gas operations under existing leases or rights-of-way.

Specific Requirements for Marine Mineral Lessees in the Gulf of Mexico
BOEM may require operational setbacks from existing oil and gas infrastructure during dredging operations to avoid direct or indirect impacts to infrastructure. Setbacks will be determined on a case-by-case basis, using guidance provided in A Study to Address the Issue of Seafloor Stability and the Impact of Sand Dredging Activities on Oil and Gas Infrastructure in the Gulf of Mexico (OCS Study MMS 2005-043).
