Safety Zone; Navy Underwater Detonation (UNDET) Exercise, Apra Outer Harbor, GU

The Coast Guard proposes to establish two recurring safety zones for navigable waters of Apra Outer Harbor and Piti, Guam. The safety zones will encompass sites designated for U.S. Navy underwater detonation (UNDET) exercises. The Coast Guard believes this safety zone regulation is necessary to protect the public and exercise participants within the affected area from possible safety hazards associated with these exercises. These safety zones will impact a small designated area of navigable waters in Apra Harbor and Piti during periods of times, many of which are of short duration, on days requested by the Navy for UNDET exercises. With the exception of exercise participants, entry of vessels or persons into the zone is prohibited unless specifically authorized by the Captain of the Port Guam. We invite your comments on this proposed rulemaking.
