The U.S. Department of the Interior's Minerals Management Service (MMS) signed a Memorandum of Understanding (MOU) with the USCG specifying which agency will be responsible for certain aspects of oil and natural gas exploration, development, production, and transportation activities on the Outer Continental Shelf (OCS). The MOU identifies 27 areas of responsibilities for both agencies. For example, MMS will be responsible for most drilling and production matters, pipeline operations, emergency shutdown systems, inspection and testing of production and drilling equipment, decommissioning platforms, and investigating oil pollution related to provisions in the OCS Lands Act.
