The Coast Guard is establishing four security zones for certain navigable waters on the Allegheny, Monongahela, and Ohio Rivers to prevent waterside threats for persons under the protection of the United States Secret Service (USSS). These security zones will be enforced intermittently and when persons under USSS protection are in the area. This rule prohibits vessels and people from entering or remaining in the zones unless specifically exempt under the provisions of this rule or granted specific permission from the Captain of the Port Pittsburgh. The regulation will enhance the safety and security of persons and property, while minimizing, to the extent possible, the impact on commerce and legitimate waterway use.
