摘要

The Coast Guard is establishing safety zones for all waters of the Upper Mississippi River (UMR) from mile 38.0 to 46.0 and from mile 78.0 to 81.0. These safety zones are needed to protect persons, property, and infrastructure from potential damage and safety hazards associated with subsurface rock removal in the Upper Mississippi River. Any deviation from the conditions and requirements put into place are prohibited unless specifically authorized by the cognizant Captain of the Port (COTP) Ohio Valley or his designated representatives.
