Title 33 - Navigation and Navigable Waters
(a) The danger zone. The waters within a sector extending seaward a distance of 3,900 yards between radial lines bearing 352° true and 61° true, respectively, from a point on Mokapu Peninsula at latitude 21°27'17" N, longitude 157°43'51" W, exclusive of the existing 500 yard wide prohibited area. The interface between the existing 500 yard prohibited area and this danger zone is defined by three points having the following coordinates:
Point A: Latitude 21°27'59" N, Longitude 157°43'56" W Point B: Latitude 21°27'52" N, Longitude 157°43'02" W Point C: Latitude 21°27'38" N, Longitude 157°43'12" W (b) The regulations. (1) Weapons firing at the Ulupau Crater Weapons Training Range may occur at any time between 6:00 a.m. and 11:00 p.m., Monday through Friday, and between 6:00 a.m. and 6:00 p.m., Saturday and/or Sunday, when required. Specific dates and hours for weapons firing, along with information regarding onshore warning signals, will be promulgated by the U.S. Coast Guard's Local Notice to Mariners. Information on weapons firing schedules may also be obtained by calling the Officer in Charge of the Range Training Facility, Headquarters and Headquarters Squadron, MCAS (telephone number 257–2067). (2) Whenever hazardous weapons (machine guns) firing is scheduled and in progress during daylight hours, two large red triangular warning pennants will be flown at each of two highly visible and widely separated locations on the shore at Ulupau Crater. (3) Whenever tactical weapons (exclusive of machine guns) firing is scheduled and in progress during daylight hours, a single large red rectangular warning flag will be flown at the two separate locations on the shore. (4) Whenever any weapons firing is scheduled and in progress during periods of darkness, flashing red warning beacons will be displayed on the shore at Ulupau Crater. (5) Boaters will have complete access to the danger zone whenever there is no weapons firing scheduled, which will be indicated by the absence of any warning flags, pennants, or beacons displayed ashore. (6) The danger zone is not considered safe for boaters whenever hazardous weapons (machine guns) firing is in progress. Hazardous weapons firing will usually be scheduled approximately twice per month, on nonconsecutive weekdays, for about eight hours on each occasion. Boaters shall expeditiously vacate the danger zone at best speed and by the most direct route whenever hazardous weapons firing is scheduled. Passage of vessels through the danger zone when hazardous weapons firing is in progress will be permitted, but boaters shall proceed directly through the area at best speed. Hazardous weapons firing will be suspended as long as there is a vessel in the danger zone. Whenever a boater disregards the publicized warning signals that hazardous weapons firing is scheduled, the boater will be personally requested to expeditiously vacate the danger zone by MCAS Kaneohe Bay military personnel utilizing a bull-horn from either a Marine helicopter or Navy crash boat. (7) The danger zone may be occupied for extended periods and with caution at individual risk whenever tactical weapons (exclusive of machine guns) firing is scheduled and in progress because of the remote possibility of a rifle round from an accidental discharge impacting outside the limits of the existing prohibited area. (8) Observation posts will be manned whenever any weapons firing is scheduled and in progress. Visibility will be sufficient to maintain visual surveillance of the entire danger zone and for an additional distance of 5 miles in all directions whenever weapons firing is in progress. (c) The Enforcing Agency. The foregoing regulations shall be enforced by the Commanding Officer, MCAS Kaneohe Bay and such agencies as he/she may designate. [46 FR 43044, Aug. 26, 1981.
