Safety Zones; Sector Upper Mississippi River Annual and Recurring Safety Zones Update

Özet

The Coast Guard is amending and updating its annual and recurring safety zones that take place in the Coast Guard Sector Upper Mississippi River area of responsibility (AOR). This regulation informs the public of regularly scheduled events that require additional safety measures through establishing a safety zone. Through this interim rule the current list of recurring safety zones is updated with revisions, additional events, and removal of events that no longer take place; and we are requesting comments on additional changes necessary to update the permanent list of recurring safety zones in Sector Upper Mississippi River's AOR. When these safety zones are enforced, vessel traffic is restricted from specified areas. Additionally, this one rulemaking project serves to provide notice of the known recurring safety zones throughout the year.
