The Minerals Management Service (MMS), a bureau in the U.S. Department of the Interior, is the Federal agency that manages the nation's natural gas, oil and other mineral resources on the outer continental shelf (OCS). The agency also collects, accounts for and disburses an average of $13.7 billion per year in revenues from Federal offshore mineral leases and from onshore mineral leases on Federal and American Indian lands. The program is national in scope and is headquartered in Washington, D.C.

The MMS is comprised of two major programs: Offshore Energy and Minerals Management and Minerals Revenue Management. The Offshore program, which manages the mineral resources on the OCS, is comprised of three regions: Alaska, Gulf of Mexico, and the Pacific. The Minerals Revenue Management program is headquartered in Washington, D.C., but operationally based in Denver, Colorado.

MMS’s mission is to manage the ocean energy and mineral resources on the Outer Continental Shelf and Federal and American Indian mineral revenues to enhance public and trust benefits, promote responsible use, and realize fair value.
