A Coast Guard-National Park Service agreement exists for both the Glen Canyon and Lake Mead National Recreational Areas; applicants shall contact the cognizant authority for approval of events in these areas.
2. (b)Special local regulations. All persons and vessels not registered with the sponsor as participants or as official patrol vessels are considered spectators.

   3. (3)The Patrol Commander (PATCOM) is empowered to control the movement of all vessels in the regulated area or to restrict vessels from entering the regulated area. The Patrol Commander shall be designated by the cognizant Coast Guard Sector Commander; will be a U.S. Coast Guard commissioned officer, warrant officer, or petty officer to act as the Sector Commander's official representative; and will be located aboard the lead official patrol vessel.

   4. (4)The Patrol Commander may, upon request, allow the transit of commercial vessels through regulated areas when it is safe to do so.
