Proposed rule · 2025-08194

Security Zone; Upper Mississippi River, Saint Louis, MO

The Coast Guard proposes establishing a permanent security zone for certain waters of the Upper Mississippi River adjacent to the Jefferson Barracks military installation, Saint Louis, MO. This proposed rulemaking would prohibit persons and vessels from operating or anchoring within the Security zone unless authorized by the Captain of the Port Sector Upper Mississippi River or a designated representative. This action is necessary to ensure no unauthorized entry into the waters adjacent to the military installation to safeguard the installation from sabotage or other subversive acts. We invite your comments on this proposed rulemaking.
