SECTION I - SPECIAL NOTICES

This section contains information of special concern to the Marine

 

OREGON – YAQUINA HEAD TO COLUMBIA RIVER – Undersea cable maintenance (Revised from LNM 03/22)

The vessel Tuna Time II, will be providing surface support for divers conducting undersea telecommunications cable work in approximate position 45-15-01 N, 123-58-39.2 W, approximately 1100 yards off the shore near Pacific City, Oregon. Operations were previously scheduled for the first week in November, but will be completed as soon as favorable weather conditions allow. The operation will take 2-3 days with dive operations running from 0700 – 1800 daily. Tuna Time II will have limited maneuverability (being anchored) while conducting operations. All vessels in the area are requested to maintain a minimum 1 NM CPA to ensure safety of divers and navigation. Tuna Time II will monitor VHF-FM channels 16 and 13. For more information, contact (904) 397-8996 or email operations@gaeaquatic.com

 

OREGON – TILLAMOOK BAY – Tillamook entrance north jetty repair work

J.E. McAmis, Inc will commence a Tillamook North Jetty Repair project for the Portland District of USACE on 28 Feb 2022. Equipment will be operating atop the jetty near Bar View Jetty State Park and the Coast Guard observation tower, on the north side of the entrance. The project is expected to continue through July 2022, and operating hours will be weekdays, daylight only.

 

COLUMBIA RIVER – PACIFIC OCEAN TO HARRINGTON POINT – Anchor recovery operations (Revised from LNM 06/22)

The anchor recovery operations occurring on Harrington Point Range on the Columbia River near RM 20.6 have concluded. The lost anchor was recovered, and the virtual AIS (V-AIS) signal at 46-14-07.249N, 123-43-00.614W, marking this obstruction will be disestablished.

 

COLUMBIA RIVER – VANCOUVER TO BONNEVILLE – Bridge maintenance notice

ODOT and Bridge Masters Inc. will be installing fiber optic conduit beneath the Oregon Slough Interstate 5 Highway Bridge (LLNR 11297) from 06 Mar – 29 Apr 2022. Work hours will be from 2100 on Sunday nights through 0500 on Friday mornings. Construction will be conducted using a under bridge inspection trucks (UBITs) that occupy a portion of the roadway and extend booms over the side of the bridge. The work vehicle will be marked with a flashing amber light on the bottom of the basket. When the work vehicle is working over the roadway, there will be a 6ft reduction in vertical navigation clearance beneath the work vehicle. Mariners are asked to stay clear of the work vehicle (at least 100ft horizontal separation) as there is a potential risk of falling construction materials and for the safety of the personnel in the work vehicle basket. The work vehicle will monitor VHF-FM Channel 16 if mariners have any concerns as they transit beneath the bridge. Contact Jake Bothe at (760) 815-3845, or Jakob.bothe@bridgemastersinc.com

 

WASHINGTON – PUGET SOUND – PORT MADISON AND PORT ORCHARD – Oceanographic Research

The University of Washington will be conducting a tidal energy study at the south end of Agate Pass from 11 – 27 Apr 2022. The R/V Russell Davis Light will be anchored in a four point mooring throughout the experiment, in approximate position 47-42-25.2 N and 122-34-13.8 W, and will display lights and shapes for a vessel at anchor. The R/V Jack Robertson will deploy and recover the mooring anchors at the start and end of the experiment. Each anchor will have a crown buoy consisting of a white float and a QW light (quick flash white). The research vessels will monitor VHF-FM channels 16, 14 and 13. The anchor lines will extend 130 yards from the vessel. All vessels are requested to stay outside of the four anchor buoys and provide a minimum clearance of 130 yards from the anchored vessel. For additional information, contact Applied Physics Laboratory, University of Washington at (206) 685-1971.

 

WASHINGTON – LAKE WASHINGTON SHIP CANAL TO LAKE UNION – Bridges Notice

The Coast Guard intends to approve a temporary deviation from the operating schedule that governs the Fremont Bridge (LLNR 18182), mile 2.6, and the University Bridge (LLNR 18235), mile 4.3, both crossing the Lake Washington Ship Canal in Seattle, WA. This deviation will accommodate the Tenacious Ten running event ON 09 Apr 2022. This deviation allows the Fremont Bridge to remain in the closed-to-navigation position from 0800 to 0830 on 09 Apr 2022, and the University Bridge may remain in the closed-to-navigation position from 0815 to 1015 on 09 Apr 22. Vessels which do not require bridge openings may continue to transit beneath these bridges during this closure period. The bridge will be required to open, if needed, for vessels engaged in emergency response operations during this closure period. If any mariner or marine stakeholder cannot support this closure period for the subject bridges, please submit objections to d13-smb-d13-bridges@uscg.mil by 09 Mar 22.

 

WASHINGTON – EVERETT HARBOR – SNOHOMISH RIVER – SR 529 Highway Bridges Notice

The Coast Guard has approved a temporary bridge deviation from the operating schedule that governs the SR-529 Highway Bridges across the Snohomish River and Steamboat Slough to support the Everett Half Marathon event on 27 Mar 2022 from 0700 to 1100. During this period, the swing spans of the SR-529 Highway Bridge (NB) (LLNR 18591.3) and the SR-529 Highway Bridge (SB) (LLNR 18591.2) across the Snohomish River, mile 3.6, at Everett, WA, and the lift spans of SR-529 Highway Bridge (NB) (LLNR 18594.11) and the SR-529 Highway Bridge (SB) (LLNR 18594.9) across Steamboat Slough, mile 1.1, at Marysville, WA, is authorized to remain in the closed-to-navigation position. The SR-529 Bridges across Steamboat Slough provide 10 feet of vertical clearance in the closed-to-navigation position at high tide. The SR-529 Bridges across the Snohomish River provide 37 feet of vertical clearance in the closed-to-navigation position at high tide. The SR-529 Bridges must open to emergency vessels responding to emergencies. An alternate route for vessels to use during this deviation period is via Union Slough.
