BILLING CODE 9110-04-P DEPARTMENT OF HOMELAND SECURITY Coast Guard 33 CFR Part 117 [Docket No. USCG-2017-0700] Drawbridge Operation Regulation; Lake Washington Ship Canal, Seattle, WA AGENCY: Coast Guard, DHS. ACTION: Notice of deviation from drawbridge regulation. SUMMARY: The Coast Guard has issued a temporary deviation from the operating schedule that governs the Montlake Bridge across the Lake Washington Ship Canal, mile 5.2, at Seattle, WA. The deviation is necessary to allow work crews to replace bridge decking.
This deviation allows a single leaf opening with a one hour advance notice during the day, and remains in the closed-to-navigation position during evening hours. DATES: This deviation is effective from 10 p.m. on August 11, 2017 to 5 a.m. on August 21, 2017.

FOR FURTHER INFORMATION CONTACT: If you have questions on this temporary deviation, call or email Mr. Steven Fischer, Bridge Administrator, Thirteenth Coast Guard District; telephone 206-220-7282, email *d13-pf-d13bridges@uscg.mil.* SUPPLEMENTARY INFORMATION: Washington Department of Transportation (WSDOT), bridge owner, has requested a temporary deviation from the operating schedule for the Montlake Bridge across the Lake Washington Ship Canal, at mile 5.2, at Seattle, WA. The deviation is necessary to accommodate work crews to conduct timely bridge deck repairs.
The Montlake Bridge in the closed-to-navigation position provides 30 feet of vertical clearance throughout the navigation channel, and 46 feet of vertical clearance throughout the center 60 feet of the bridge; vertical clearance references to the Mean Water Level of Lake Washington. When half the span is open, single leaf, 46 feet of vertical clearance will be reduced throughout the center 30 feet of the bridge. To facilitate this construction event, single leaf operation will provide 75 feet of horizontal clearance.
The normal operating schedule for the Montlake Bridge operates in accordance with 33 CFR 117.1051(e). The deviation period and span operation is described in the table below: Time/date start Time/date end Action 10 p.m. Aug 11, 2017 5 a.m. Aug 12, 2017 span in the closed-to-navigation position. 5 a.m. Aug 12, 2017 6 p.m. Aug 12, 2017 single leaf opening w/one hour notice. 6 p.m. Aug 12, 2017 5 a.m. Aug 13, 2017 span in the closed-to-navigation position. 5 a.m. Aug 13, 2017 6 p.m.
Aug 13, 2017 single leaf opening w/one hour notice. 6 p.m. Aug 13, 2017 5 a.m. Aug 14, 2017 span in the closed-to-navigation position. 10 p.m. Aug 18, 2017 5 a.m. Aug 19, 2017 span in the closed-to-navigation position. 5 a.m. Aug 2017 6 p.m. Aug 19, 2017 single leaf opening w/one hour notice. 6 p.m. Aug 19, 2017 5 a.m. Aug 20, 2017 span in the closed-to-navigation position. 5 a.m. Aug 20, 2017 6 p.m. Aug 20, 2017 single leaf opening w/one hour notice. 6 p.m. Aug 20, 2017 5 a.m.
Aug 21, 2017 span in the closed-to-navigation position. Waterway usage on the Lake Washington Ship Canal ranges from commercial tug and barge to small pleasure craft. Vessels able to pass through the bridge in the closed-to-navigation position may do so at anytime. The bridge will be able to open for emergency vessels in route to a call when an hour notice is given to the bridge operator, and a single leaf opening will be provided. The Lake Washington Ship Canal has no immediate alternate route for vessels to pass.
The Coast Guard will also inform the users of the waterways through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so that vessels can arrange their transits to minimize any impact caused by the temporary deviation. In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.
Dated: July 20, 2017. Steven Michael Fischer, Bridge Administrator, Thirteenth Coast Guard District. [FR Doc. 2017-15795 Filed 7-26-17; 8:45 am]
