[Docket No. USCG-2010-1084]


Drawbridge Operation Regulation; Upper Mississippi River, 
Clinton, IA

AGENCY: Coast Guard, DHS.

ACTION: Notice of temporary deviation from regulations.

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

SUMMARY: The Commander, Eighth Coast Guard District, has issued a 
temporary deviation from the regulation governing the operation of the 
Clinton Railroad Drawbridge across the Upper Mississippi River, mile 
518.0, at Clinton, Iowa. The deviation is necessary to allow the bridge 
owner time to perform preventive maintenance that is essential to the 
continued safe operation of the drawbridge. Maintenance is scheduled in 
the winter and when there is less impact on navigation; instead of 
scheduling work in the summer, when river traffic increases. This 
deviation allows the bridge to open on signal if at least 24 hours 
advance notice is given.

DATES: This deviation is effective from 12:01 a.m., December 15, 2010 
to 9 a.m., March 1, 2011.

SUPPLEMENTARY INFORMATION: The Union Pacific Railroad requested a 
temporary deviation for the Clinton Railroad Drawbridge, across the 
Upper Mississippi River, mile 518.0, at Clinton, Iowa to open on signal 
if at least 24 hours advance notice is given for 77 days from 12:01 
a.m., December 15, 2010 to 9 a.m., March 1, 2011 to allow the bridge 
owner time for preventive maintenance. The Clinton Railroad Drawbridge 
currently operates in accordance with 33 CFR 117.5, which states the 
general requirement that drawbridges shall open promptly and fully for 
the passage of vessels when a

[[Page 78163]]

request to open is given in accordance with the subpart.
    There are no alternate routes for vessels transiting this section 
of the Upper Mississippi River.
    Winter conditions on the Upper Mississippi River coupled with the 
closure of Army Corps of Engineer's Lock No. 20 (Mile 343.2 UMR), Lock 
No. 21 (Mile 324.9 UMR) and Lock No. 22 (Mile 301.2 UMR) from January 
3, 2011 to February 28, 2011 will preclude any significant navigation 
demands for the drawspan opening.
    The Clinton Railroad Drawbridge, in the closed-to-navigation 
position, provides a vertical clearance of 18.7 feet above normal pool. 
Navigation on the waterway consists primarily of commercial tows and 
recreational watercraft. The drawbridge will open if at least 24-hours 
advance notice is given. This temporary deviation has been coordinated 
with waterway users.
    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: December 2, 2010.
Eric A. Washburn,
Bridge Administrator.
