Safety Zone; Apra Harbor, Guam
The Coast Guard proposes to revise the existing safety zones currently in effect at Naval Wharf Kilo in Apra Outer Harbor, Guam, by adding a 500-yard permanent safety zone, hereinafter referred to as Safety Zone D, to provide a buffer between the explosives regularly handled on Naval Wharf Kilo, and the general public and maritime operators. The addition of Safety Zone D would also reduce the frequency of enforcement of Safety Zones A and B. This action also eliminates from the regulation the requirement to post a sign when Safety Zones A or B are being enforced; during such enforcement periods, notification will occur via a slight modification of the displayed visual indicators already codified in the existing regulation as well as via a broadcast notice to mariners. This rulemaking will better meet the needs of the community and reduce the frequency that restrictions must be imposed through the addition of a less restrictive permanent safety zone, thereby enhancing the safe and efficient use of Apra Outer Harbor Channel in the vicinity of Naval Wharf Kilo. We invite your comments on this proposed rulemaking.
Drawbridge Operation Regulation; Upper Mississippi River, IA
The Coast Guard proposes to change the operating schedule that governs the draws of all bridges between Lock and Dam No. 14, mile 493.3, and Lock and Dam No. 10, mile 615.1, on the Upper Mississippi River by adding a 24-hour notice requirement for openings during the winter season. This proposed rule would allow the drawbridges to remain in the closed-to-navigation position for extended periods allowing the owners of the drawbridges to perform preventive maintenance that is essential to the safe operation of the drawbridges. This proposed rule would allow for flexibility in beginning these special operating schedules each year based on the arrival of winter weather.
