B. Background

On September 16, 2004, a mudslide resulted from Hurricane Ivan's storm surge that toppled the Mississippi Canyon (MC) 20 Platform A. The platform's wells were covered by more than 100-feet of mud and sediment. As a result of structural damage, plumes containing crude oil and gas have been discharging into the Gulf of Mexico, creating a sheen on the surface of the water.

The responsible party for this incident has undertaken an operation to install a containment dome over the affected area, which would catch the oil rising from the sea floor. Many vessels continue to operate in the affected area. Anchoring, mooring, or loitering in the area above the containment dome could potentially damage the dome, or reduce its effectiveness.

C. Need for Correction

The Coast Guard published a document in the Federal Register on April 29, 2013, for this Regulated Navigation Area (RNA). (78 FR 24987). As noted in that document, the center of this RNA was established to surround an oil wellhead that was leaking oil after structural damage from a hurricane and mudslide. However, the latitude and longitude of that oil platform were incorrectly noted. The correct center of the regulated navigation area established by the interim rule is 28°56′12.619″ N, 088°58′10.303″ W. This correction revises the latitude and longitude for the center of this RNA to accurately reflect the location of the oil wellhead.
