33 CFR Part 117

[Docket No. USCG-2017-0510]


Drawbridge Operation Regulation; Sacramento River, Rio Vista, CA

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 Rio Vista Drawbridge across the 
Sacramento River, mile 12.8, at Rio Vista, CA. The deviation is 
necessary to allow the bridge owner to make necessary emergency repairs 
to the bridge. This deviation allows the bridge to open with one hour 
advance notice during the deviation period.

DATES: This deviation is effective from 7 p.m. on June 16, 2017 to 4 
a.m. on July 1, 2017.

FOR FURTHER INFORMATION CONTACT: If you have questions on this 
temporary deviation, call or email Carl T. Hausner, Chief, Bridge 
Section, Eleventh Coast Guard District; telephone 510-437-3516; email 
Carl.T.Hausner@uscg.mil.

SUPPLEMENTARY INFORMATION: The California Department of Transportation 
has requested a temporary change to the operation of the Rio Vista 
Drawbridge, mile 12.8, over Sacramento River, at Rio Vista, CA. The 
drawbridge navigation span provides a vertical clearance of 18 feet 
above Mean High Water in the closed-to-navigation position. In 
accordance with 33 CFR 117.5, the draw opens on signal. Navigation on 
the waterway is commercial, search and rescue, law enforcement, and 
recreational.
    The drawspan will require a one hour advance notice at three 
specified periods: (1) From 7 p.m. on June 16, 2017 to 4 a.m. on June 
17, 2017; (2) from 8 p.m. on June 24, 2017 to 7 a.m. on June 25, 2017; 
and (3) from 7 p.m. on June 30, 2017 to 4 a.m. on July 1, 2017, to 
allow the bridge owner to make emergency repairs to the bridge deck. A 
one hour advance notice will give enough time for the contractor to 
clear away equipment and workers before the drawspan can safely open 
for transiting vessels. Scaffolding will be installed below the bridge 
deck from June 16, 2017 through July 1, 2017, reducing the vertical 
clearance by 4 feet, and will extend from the west tower 48 feet into 
the navigational channel. This temporary deviation has been coordinated 
with the waterway users.

[[Page 27424]]

No objections to the proposed temporary deviation were raised.
    Vessels able to pass through the bridge in the closed position may 
do so at anytime. The bridge will be able to open for emergencies with 
one hour advance notice. There is no immediate alternate route for 
vessels to pass. The Coast Guard will also inform the users of the 
waterway through our Local and Broadcast Notices to Mariners of the 
change in operating schedule for the bridge so vessel operators 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 effective 
period of this temporary deviation. This deviation from the operating 
regulations is authorized under 33 CFR 117.35.

    Dated: June 12, 2017.
C.T. Hausner,
District Bridge Chief, Eleventh Coast Guard District.
