Coast Guard June 2, 2023 – Federal Register Recent Federal Regulation Documents

The Coast Guard will enforce the safety zone in the navigable waters of Suisun Bay, off Concord, CA, in support of explosive on- loading to Military Ocean Terminal Concord (MOTCO) from June 4, 2023, through June 10, 2023. This safety zone is necessary to protect personnel, vessels, and the marine environment from potential explosion within the explosive arc. The safety zone is open to all persons and vessels for transitory use, but vessel operators desiring to anchor or otherwise loiter within the safety zone must obtain the permission of the Captain of the Port San Francisco or a designated representative. All persons and vessels operating within the safety zone must comply with all directions given to them by the Captain of the Port San Francisco or a designated representative.

The Coast Guard will enforce the special local regulations for the annual Escape From Alcatraz Swim on June 11, 2023 to provide for the safety of life on navigable waterways in the San Francisco Bay during this event. Our regulation for marine events in Northern California identifies the regulated area for this event in San Francisco, CA. During the enforcement period, unauthorized persons or vessels are prohibited from entering into, transiting through, or loitering or anchoring in the regulated area, unless authorized by the designated Patrol Commander (PATCOM) or other Federal, State, or local law enforcement agencies on scene to assist the Coast Guard in enforcing the regulated area.

The Coast Guard is temporarily modifying the operating schedule that governs the Dearborn Street Bridge, mile 1.13, over the Main Branch of the Chicago River at Chicago, Illinois. During this maintenance period, the bridge need only operate one leaf while the other leaf remains secured to masted navigation. Vessels able to pass under the bridge without an opening may do so at any time.
