[Docket No. USCG-2017-0510]


Drawbridge Operation Regulation; Sacramento River, Rio Vista, CA

AGENCY: Coast Guard, DHS.

ACTION: Notice of deviation from drawbridge regulation; modification.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard has modified a temporary deviation from the 
operating schedule that governs the Rio Vista Drawbridge across 
Sacramento River, mile 12.8, at Rio Vista, CA. The modified deviation 
extends the period the bridge may open with one hour advance notice and 
is necessary to allow the bridge owner to make necessary emergency 
repairs to the bridge.

DATES: This modified deviation is effective without actual notice from 
July 5, 2017 through 4 a.m. on July 15, 2017. For the purposes of 
enforcement actual notice will be used from June 28, 2017 until July 5, 
2017.

FOR FURTHER INFORMATION CONTACT: If you have questions on this

Section, Eleventh Coast Guard District; telephone 510-437-3516; email

SUPPLEMENTARY INFORMATION: On June 15, 2017, the Coast Guard published 
a temporary deviation entitled ``Drawbridge Operation Regulation; 
Sacramento River, Rio Vista, California'' in the Federal Register (82 
FR 27423). That temporary deviation, from 7 p.m. on June 16, 2017 to 4 
a.m. on July 1, 2017, allows the drawspan to open on one hour advance 
notice at three specified time periods. The bridge owner, California 
Department of Transportation, has requested a modification of the 
currently published deviation to extend from 4 a.m. on July 1, 2017 to 
4 a.m. on July 15, 2017 in order to complete the necessary repairs to 
the bridge deck.
    The Rio Vista Drawbridge, mile 12.8, across the Sacramento River, 
has 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 one 
specified period: From 6 p.m. on July 14, 2017 to 4 a.m. on July 15, 
2017. 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 July 1, 2017 through July 15, 2017, reducing the 
vertical clearance by 4 feet, and will extend from the west tower 48 
feet into the navigational channel. This temporary deviation 
modification has been coordinated with the waterway users. No 
objections to the proposed temporary deviation modification were 
raised.

[[Page 30969]]

    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 28, 2017.
C.T. Hausner,
District Bridge Chief, Eleventh Coast Guard District.
