Drawbridge Operation Regulations; Sacramento River, at Isleton, 
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 
Isleton Drawbridge across the Sacramento River, mile 18.7, at Isleton, 
CA. This deviation allows for a 12-hour notice for openings. The 
deviation is necessary for the bridge owner, the California Department 
of Transportation (Caltrans), to coordinate vessel traffic with their 
scheduled critical maintenance and operating upgrades.

[[Page 9855]]


DATES: This deviation is effective from 12:01 a.m. on April 21, 2007 
through 11:59 p.m. on May 25, 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.

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 Isleton Drawbridge, mile 18.7, Sacramento River, at 
Isleton, CA. The Isleton Drawbridge navigation span provides a vertical 
clearance of 13 feet above Mean High Water in the closed-to-navigation 
position. The draw opens on signal between 6 a.m. and 10 p.m. from May 
1 through October 31, and between 9 a.m. and 5 p.m. from November 1 
through April 30. At all other times, it opens on signal if at least 
four hours notice is given as required by 33 CFR 117.189. Navigation on 
the waterway is recreational, search and rescue and commercial traffic 
hauling materials for levee repair. Caltrans requested a change to the 
12-hour notice for openings from 12:01 a.m. on April 21, 2007 through 
11:59 p.m. on May 25, 2007. During this time the control house will be 
replaced, motors refurbished, and operating machinery will be upgraded, 
resulting in manual control of the drawspan. This temporary deviation 
has been coordinated with waterway users. No objections to the proposed 
temporary rule 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(c), this work will be performed 
with all due speed in order to return the bridge to normal operation as 
soon as possible. This deviation from the operating regulations is 
authorized under 33 CFR 117.35.

    Dated: February 23, 2007.
J.A. Breckenridge,
Rear Admiral, U.S. Coast Guard, Commander, Eleventh Coast Guard 
District.
