Alternate Tonnage Threshold for Oil Spill Response Vessels
The Coast Guard is establishing an alternate size threshold based on the measurement system established under the International Convention on Tonnage Measurement of Ships, 1969, for oil spill response vessels, which are properly certificated under 46 CFR chapter I, subchapter L. The present size threshold of 500 gross register tons is based on the U.S. regulatory measurement system. This final rule provides an alternative for owners and operators of offshore supply vessels that may result in an increase in oil spill response capacity and capability. This final rule adopts, without change, the interim rule amending 46 CFR part 126 published in the Federal Register on Monday, December 12, 2011.
Safety Zones; Sellwood Bridge Project, Willamette River; Portland, OR
The Coast Guard is establishing two safety zones to remain in effect throughout the duration of the construction and renewal of the Sellwood Bridge located on the Willamette River in Portland, Oregon. This action is necessary to ensure the safety of vessels transiting in close proximity to cranes, barges, and temporary structures associated with this construction project. During the effective period, all vessels will be required to remain at the prescribed safe distance from the construction area while transiting in the vicinity of the Sellwood Bridge project; however, the establishment of these safety zones does not entirely close this section of the Willamette River. The section of the Willamette River between the safety zones will remain open for vessel transits, and it will have a minimum channel width of 138 feet at all times.
Safety Zone; NOBLE DISCOVERER, Outer Continental Shelf Drillship, Chukchi and/or Beaufort Seas, AK
The Coast Guard is establishing a 500-meter safety zone in the navigable waters, from the surface to seabed, around the DRILLSHIP NOBLE DISCOVERER, while anchored or deploying and recovering moorings on location in order to drill exploratory wells at various prospects located in the Chukchi and/or Beaufort Seas Outer Continental Shelf, Alaska, on or about July 1, 2012 through November 30, 2012. See TABLE 1. The purpose of the temporary safety zone is to protect the drillship from vessels operating outside the normal shipping channels and fairways. Placing a safety zone around the drillship will significantly reduce the threat of allisions, which could result in oil spills, and releases of natural gas, and thereby protect the safety of life, property, and the environment. Lawful demonstrations may be conducted outside of the safety zone.
