33 CFR Part 117

[Docket No. CGD11-07-013]


Drawbridge Operation Regulations; Sacramento River, Rio Vista, CA

AGENCY: Coast Guard, DHS.

ACTION: Notice of temporary deviation from regulations.

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

SUMMARY: The Commander, Eleventh Coast Guard District, has issued a 
temporary deviation from the regulation governing the operation of the 
Rio Vista Drawbridge across the Sacramento River, mile 12.8, at Rio 
Vista, CA. The deviation is necessary to allow the bridge owner, the 
California Department of Transportation (Caltrans), to conduct required 
maintenance of the drawspan. This deviation allows for a 4-hour notice 
for openings.

DATES: This deviation is effective from 9 p.m. September 5, 2007 
through 5 a.m. on October 21, 2007.

ADDRESSES: Materials referred to in this document are available for 
inspection or copying at Commander (dpw), Eleventh Coast Guard 
District, Building 50-2, Coast Guard Island, Alameda, CA 94501-5100, 
between 8 a.m. and 4 p.m., Monday through Friday, except Federal 
holidays. The telephone number is (510) 437-3516. The Eleventh Coast 
Guard District maintains the public docket for this temporary 
deviation.

FOR FURTHER INFORMATION CONTACT: David H. Sulouff, Chief, Bridge 
Section, Eleventh Coast Guard District, telephone (510) 437-3516.

SUPPLEMENTARY INFORMATION: Caltrans requested a temporary change to the 
operation of the Rio Vista Drawbridge, mile 12.8, Sacramento River, at 
Rio Vista, CA. The Rio Vista Drawbridge navigation span provides a 
vertical clearance of 17 feet above Mean High Water in the closed-to-
navigation position. The draw opens on signal as required by 33 CFR 
117.5. Navigation on the waterway consists of both commercial and 
recreational vessels.
    This deviation allows the bridge to require a 4-hour notice for 
openings. The 4-hour notice for openings during the maintenance period, 
from 9 p.m. September 5, 2007 through 5 a.m. on October 21, 2007, will 
allow Caltrans to clear the drawspan of maintenance equipment so as not 
to delay approaching vessels. This temporary deviation has been 
coordinated with all affected waterway users. No objections to the 
proposed temporary deviation were raised.
    Vessels that can transit the bridge, while in the closed-to-
navigation position, may continue to do so at any time.
    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: August 22, 2007.
C.E. Bone,
Rear Admiral, U.S. Coast Guard, Commander, Eleventh Coast Guard 
District.
