The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by underwater survey work on Line 5 Pipeline. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port, Sector Northern Great Lakes, or their designated representative.
