NPRM Notice of proposed rulemaking Section U.S.C. United States Code
II. Background, Purpose, and Legal Basis On July 20, 2021, Ballard Marine Construction notified the Coast Guard that it would begin construction for their CBWTP Outfall Diffuser Improvements Project from 12:01 a.m.
on October 1, 2021, through 11:59 p.m.
on February 28, 2022, to remove and replace existing pipeline along with dredging operations. The construction project includes the two Outfall easements 001 and 003 being dredged with diver assistance to expose existing risers and diffusers. The existing risers and diffuser valves will be removed and disposed of. In their place, longer risers will be attached along with new diffuser valves. Additionally, the Outfalls will be dredged to remove the treated effluent that has settled inside the main trunk lines if needed. All diver work will be supported by a floating crane barge approximately 50 feet by 185 feet that will be anchored during the duration of work upon each of the two specified Outfalls and will be moved within the zone approximately four times. The Captain of the Port Sector Columbia River COTP has determined that potential hazards associated with the construction project would be a safety concern for anyone within the designated area of the CBWTP Outfall Diffuser Improvements.
The purpose of this rulemaking is to ensure the safety of vessels and the navigable waters within the designated area of the CBWTP Outfall Diffuser Improvements construction project. The Coast Guard is proposing this rulemaking under authority in 46 U.S.C.
70034 previously 33 U.S.C. 1231.
III. Discussion of Proposed Rule The COTP is proposing to establish a safety zone from October 1, 2021, through February 28, 2022. The safety zone would cover all navigable waters of the Columbia River, surface to bottom, approximately 300 yards to the east and west side of the Burlington Northern Railroad Bridge on the Oregon side of the Columbia River from the shoreline to the outside of the main navigational channel; specifically beginning at the shoreline at 453726.2
N, 1224146.91 W, northeast to 453733.206 N, 1224137.699 W, southeast to 453723.4 N, 1224118.1
W, thence southwest to 453716.27 N, 1224130.75 W, and along the shoreline back to the beginning point.
The duration of the zone is intended to ensure the safety of vessels and these
