Notice of Safety Zone for July 13

by Captain James B. Pruett
U.S. Coast Guard Sector Guam

Notice is hereby given of a safety zone being established on July 13, 2017 approximately 700 yards west, south-west of Family Beach, Glass Breakwater Apra Harbor Guam. The safety zone is being established for the safety of the public and exercise participants during a Navy underwater detonation training exercise. It will be enforced from 8 a.m. until4 p.m. unless cancelled earlier by the Captain of the Port (COTP) Guam.

The safety zone is bounded by a circle with a 700-yard radius above and below the surface centered at 13°

27' 42" North Latitude and 144° 38' 30" East Longitude (NAD 1983).

Entry of vessels or persons into this safety zone will be prohibited unless authorized by the COTP Guam. The COTP Guam can be contacted at 671-355-4824 or VHF Channel 16/22A. When the area has been cleared of safety hazards, the COTP Guam will cease enforcement of the safety zone and will announce that fact via Broadcast Notice to Mariners.


Title 33, CFR, Part 165.23 prohibits any unauthorized person or vessel from entering or remaining in this safety zone. Any person entering this safety zone without the permission of the Captain of the Port is subject to a civil penalty of up to $40,000 and/or criminal penalties of up to $50,000 and up to five years imprisonment, or both.


After the Coast Guard analyzed the scope and potential impacts associated with establishment of a safety zone, the Coast Guard is issuing this temporary final rule to establish a safety zone without prior notice and opportunity to comment pursuant to authority under section 4(a) ofthe Administrative Procedure Act (APA)

(5 u.s.c. 553(b)).

The temporary final rule and resulting restricted navigation area established by this rulemaking relates to the establishment of the safety zone itself (e.g. size, shape, duration). It does not address or regulate the underwater detonation training exercise. For information on the underwater detonation training activity, the Navy environmental impact statement and public involvement is available at

Even though this rule is being implemented prior to opportunity to comment through the formal rulemaking process, the Coast Guard encourages the public or any interested party to provide comment on the establishment of this safety zone and any potential impact it may have. Comments can be provided to the Waterways Management Branch at Coast Guard Sector Guam; telephone (671) 355-4835, email
