Security Zones; Protection of Military Cargo, Captain of the Port Zone Puget Sound, WA
Key claim: The Coast Guard is enforcing temporary security zones in Commencement Bay’s Blair and Sitcum Waterways from November 8 through November 12, 2026, restricting vessel movement without permission during military cargo operations.
Abstract
(Rule · Homeland Security Department, Coast Guard) The Coast Guard will enforce security zones for the Protection of Military Cargo from November 8 through November 12, 2026, to provide for the security of life and vessels on navigable waterways during this event. Our regulation for Protection of Military Cargo within the Captain of the Port Zone Puget Sound, WA identifies the security zones for this event in the Blair Waterway and Sitcum Waterway in Commencement Bay, WA. During the enforcement periods, the operator of any vessel in the regulated area must comply with directions from the Captain of the Port or a designated representative.
Why this matters
The enforcement temporarily limits vessel access in two Commencement Bay waterways to protect military cargo handling. It applies existing security-zone rules during November 8–12, 2026, rather than creating a new permanent restriction, with practical consequences for vessel movements during that period.
