The Coast Guard is proposing to establish a temporary safety zone for certain navigable waters on the Intercoastal Waterway portion of Biscayne Bay in Miami, FL. The safety zone is needed to protect spectators, vessels, and the marine environment from potential hazards associated with event proceedings. This proposed rulemaking would prohibit persons and vessels from being in the safety zone unless specifically authorized by the Captain of the Port, Sector Miami. We invite your comments on this proposed rulemaking.
