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.

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.

Rear Admiral, U.S. Coast Guard, Commander, Eleventh Coast Guard District.
