Which authority establishes a security zone?

The establishment of a security zone is primarily the responsibility of the Captain of the Port (COTP) or the District Commander. The COTP is a Coast Guard officer who has jurisdiction over a specific port, and they are charged with ensuring safety and security in that area, which includes the authority to create security zones when necessary. These zones are designated areas where access is restricted to protect vessels, ports, and maritime facilities from potential threats or hazards.

In practice, the COTP assesses various factors, such as national security, public safety, and environmental considerations, when determining the need for a security zone. The COTP can issue regulations and enforce security measures, making their authority particularly significant in maritime operations.

While other entities, such as the Port Authority or Maritime Administration, may have roles in maritime operations or security planning, they do not have the same direct regulatory authority to establish security zones like the COTP or District Commander does.
