(1) No person, vessel, or other watercraft, other than a vessel owned and operated by the United States, shall enter or remain in the danger zone, or within a portion or portions thereof, when closed to public access, as provided in paragraph (b)(2) of this section, except by permission of the Commanding Officer, Naval Construction Battalion Center, Gulfport or such other person(s) as he or she may designate.

(2) The danger zone, or a portion or portions thereof, will be closed, for riverine, weapons, or other dangerous naval training, by placement of Government picket boats at the northern and southern boundaries in the East Pearl River, or at such other location(s) within the danger zone as may be determined to be sufficient to protect the public.

Once the danger zone, or location(s) within the danger zone, has been cleared, picket boats will remain in position, upstream and downstream, until it is safe to re-open the area(s) to public access.

(3) Riverine, weapons, and other dangerous naval training may occur on any day of the week, typically, but not exclusively, in periods of two to eight hours, between 6 a.m. and 6 p.m. Training may occur at night, in darkness.
