Coast Guard Sets Temporary Security Zone in Apra Harbor, Guam

The U.S. Coast Guard is establishing a temporary security zone in specific navigable waters of the Philippine Sea within Apra Harbor, Guam. This rule creates a restricted area where vessels and persons are prohibited from entering unless they receive specific authorization from the Captain of the Port, Forces Micronesia/Sector Guam.

Why it matters: This is a standard, recurring administrative action. It does not change permanent laws or create a new permanent restriction. It simply formalizes the Coast Guard’s authority to close off specific waterways during high-profile visits by protected officials. For most people, this is a minor operational detail that only becomes relevant if a major government delegation arrives in Guam.

Who it affects

• Vessel operators and mariners navigating Apra Harbor
