Outer Continental Shelf Official Protraction Diagrams and 
Supplemental Official Outer Continental Shelf Block Diagrams

AGENCY: Bureau of Ocean Energy Management (BOEM), Interior.

ACTION: Availability of revised North American Datum of 1927 (NAD 27) 
Outer Continental Shelf Official Protraction Diagrams and Two Lease 
Maps Diagrams.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that effective with this publication, 
certain NAD 27-based Outer Continental Shelf (OCS) Official Protraction 
Diagrams (OPDs) and two Lease Maps depicting geographic areas located 
in the Gulf of Mexico with revision dates as indicated are now 
available. BOEM, in accordance with its authority and responsibility 
under the OCS Lands Act, is updating the maps used for the description 
of renewable energy, mineral, and oil and gas lease sales in the 
geographic areas they represent.
    BOEM produces and maintains the official marine cadastre for the 
OCS areas of the United States. The marine cadastre is a comprehensive 
spatial data infrastructure whereby rights, restrictions and 
responsibilities in the marine environment can be assessed, 
administered and managed. The marine cadastre includes the block grids 
and official boundaries, which provide the base for nearly all of the 
BOEM offshore maps and leasing processes. It also gives BOEM the means 
to define, describe, analyze, and account for every acre/hectare of 
federal offshore submerged lands.
    Pursuant to the ``Agreement between the United Mexican States and 
the United States of America Concerning Transboundary Hydrocarbon 
Reservoirs in the Gulf of Mexico,'' which went into effect on July 18, 
2014, certain activities carried out within three (3) statute miles of 
the U.S.-Mexico maritime boundary in the Gulf of Mexico trigger 
obligations for the United States related to such activities within its 
jurisdiction. The following OPDs and Lease Maps (dated October 1, 2014) 
have been revised to reflect this ``Transboundary Three Statute Mile 
Line.''
