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.

[Docket No. FMCSA–2005–21323] 

RIN–2126–AA91 

Parts and Accessories Necessary for 

Safe Operation: Surge Brake 

Requirements 

AGENCY: Federal Motor Carrier Safety 

Administration (FMCSA), DOT. 

ACTION: Final rule. 

SUMMARY: FMCSA amends the Federal 

Motor Carrier Safety Regulations to 

allow the use of automatic hydraulic 

inertia brake systems (surge brakes) on 

trailers when the ratios of gross vehicle 

weight ratings (GVWR) for the towingvehicle and trailer are within certain 

limits. A surge brake is a self-contained 

permanently closed hydraulic brake 

system activated in response to the 

braking action of the towing vehicle. 

The amount of braking force developed 

by the trailer surge-brake system is 

proportional to the ratio of the towing 

vehicle to trailer weight and 

deceleration rate of the towing vehicle. 

This action is in response to a petition 

for rulemaking from the Surge Brake 

Coalition (Coalition).
