Drawbridge Operation Regulation; Upper Mississippi River, Hannibal, MO
The Coast Guard has issued a temporary deviation from the operating schedule that governs the Hannibal Railroad Drawbridge across the Upper Mississippi River, mile 309.9, at Hannibal, Missouri. The deviation is necessary to allow the bridge owner time to replace critical control components that are essential to the continued safe operation of the drawbridge. The work is scheduled in the winter, when the impact on navigation is minimal, instead of scheduling the work at other times in the year, when river traffic is prevalent. This deviation allows the bridge to remain in the closed-to-navigation position for 39 days.
Carriage of Conditionally Permitted Shale Gas Extraction Waste Water in Bulk
The Coast Guard announces the availability of a proposed policy letter concerning the carriage of shale gas extraction waste water in bulk via barge, and invites public comment.

The policy letter also defines the information the Coast Guard may require the barge owner to provide and specifies the additional requirements the Coast Guard is considering imposing on such barges. Upon reviewing comments received on this proposed policy letter, Coast Guard will issue the final policy letter and specify its effective date.
