The Coast Guard seeks input from the public on a proposed change to the demarcation line in the New York Harbor. We request public input to help in assessing the current state of navigation safety and regulation in the New York Harbor area and associated waterways which make up the approaches. This information will support our understanding of the diverse array of waterways users and who this change may affect. Coast Guard requests information on whether we should make a change and how an earlier or later change in the demarcation line impacts vessel operations and transit.
