Agency: Coast Guard, DHS
Action: Notice of deviation from drawbridge regulations
Citation: FR Doc. 2014-29212 · Docket No. USCG-2014-0875 · 33 CFR 117

Summary

The Coast Guard has issued a temporary deviation from the operating schedule that governs 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 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. It further allows the bridge to open on signal if at least 72-hours advance notice is given from January 5, 2015 to February 13, 2015.

Dates

This deviation is effective from 5 p.m., December 15, 2014 until 9 a.m., March 1, 2015.

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 76 days from 5 p.m., December 15, 2014 to 9 a.m., March 1, 2015 for scheduled maintenance on the bridge. The deviation further allows the bridge to open on signal if at least 72-hours advance notice from 8 a.m. January 5, 2015 until 5 p.m. February 13, 2015. The Clinton Railroad Drawbridge currently operates in accordance with 33 CFR 117.5, which states the general requirement that drawbridge shall open on signal. 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. 17 (Mile 437.1 UMR) and Lock No. 20 (Mile 343.2 UMR) from 7 a.m. January 5, 2015 until 12 p.m., March 6, 2015 will preclude any significant navigation demands for the drawspan opening. In addition, Army Corps Lock No. 12 (Mile 556.7 UMR) and Lock No. 13 (Mile 522.5 UMR) will be closed from 7:30 a.m., December 15, 2014 until 11 a.m. March 4, 2015. 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 and will not be significantly impacted. This temporary deviation has been coordinated with waterway users and will not be significantly impacted. No objections were received. In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35. Dated: November 25, 2014. Eric A. Washburn, Bridge Administrator, Western Rivers.
