NTL No. 99-G07
Effective Date: May 3, 1999
NOTICE TO LESSEES AND OPERATORS OF FEDERAL OIL, GAS, AND SULPHUR
LEASES AND PIPELINE RIGHT-OF-WAY HOLDERS
IN THE OUTER CONTINENTAL SHELF, GULF OF MEXICO OCS REGION
U. S. Air Force Communication Towers
This Notice to Lessees and Operators (NTL) supersedes our guideline letter on U. S. Air Force communication towers, dated November 21, 1990.
In 1990, the U.S. Air Force, Eglin Air Force Base, notified the Minerals Management Service that seven communication towers had been constructed offshore Mobile, Alabama. These towers are approximately 100 to 150 feet tall and make up the Air Combat Maneuvering Instrumentation System. A clear line of sight between the master tower and each remote tower, as well as freedom from electromagnetic interference, must be maintained to protect their utility.
Enclosure No. 1 is a map of the area showing the specific locations of the towers and the lines of sight between the master tower and each remote tower. Enclosure No. 2 lists the towers showing the XY coordinate values of their locations. Enclosure No. 3 lists the points (keyed to the map) at which the lines of sight between the master tower and remote towers cross the OCS blocks in the area. This listing shows the XY coordinate values for each of these crossing points.
Since oil and gas exploration, development, or production activity could compromise the military use of these communication towers, the Gulf of Mexico OCS Region will apply the following restrictions when reviewing Exploration Plans, Development Operations Coordination Documents, and pipeline applications proposing activities in the area:
