Safety Zone; Massachusetts Bay, Boston, MA

What it does

The Coast Guard is proposing to establish a temporary safety zone for a certain navigable water of Massachusetts Bay, 22 miles northeast of Boston, MA. The safety zone is needed to protect personnel, vessels, and the maritime public from potential hazards created by subsea demolition operations. This proposed rulemaking would prohibit persons and vessels from entering the safety zone unless specifically authorized by the Captain of the Port Sector Boston or a designated representative. We invite your comments on this proposed rulemaking.
