AGENCY:

Coast Guard, DHS.

ACTION:

Notice of deviation from drawbridge regulation.

SUMMARY:

This deviation is necessary to provide for the safe movement of vehicular traffic during major plant reconstruction on one side of the waterway and the resulting change in work schedule and increase in workforce transiting the bridge. This deviation allows the bridge to remain temporarily closed to navigation for an additional one hour in the evening during weekdays for two months.

SUPPLEMENTARY INFORMATION:

A member of the Louisiana State Legislature requested a temporary deviation from the operating schedule on the SR 23 vertical lift span bridge, also known as the Judge Perez Bridge, across the Gulf Intracoastal Waterway (Algiers Alternate Route), mile 3.8, at Belle Chasse, Plaquemines Parish, Louisiana. The deviation requested allows the bridge to remain closed to navigation for an additional one hour in the evening, Monday through Friday, for two months.

The Louisiana Legislature makes this request to support and assist in the safe movement of increased vehicular traffic across the bridge during the evening hours, resulting from a change in the work schedule and increased work force related to a major plant reconstruction at the Conoco/Phillips Refinery in Alliance. This temporary deviation will also help to minimize the effects of the additional traffic on local residents.

Presently, in accordance with 33 CFR 117.451(b), the draw shall open on signal; except that, from 6 a.m. to 8:30 a.m. and from 3:30 p.m. to 5:30 p.m. Monday through Friday, except Federal holidays, the draw need not open for the passage of vessels.

This temporary deviation allows the vertical lift bridge to remain closed to navigation for one additional hour in the afternoon to extend the afternoon curfew hours from 3:30 p.m. to 6:30 p.m. Monday through Friday from Wednesday, March 5, 2014 through Wednesday, April 30, 2014. In case of an emergency, the bridge will be able to open for the passage of vessels.

The SR 23 vertical lift span drawbridge across the Gulf Intracoastal Waterway (Algiers Alternate Route), mile 3.8, at Belle Chasse, Louisiana has a vertical clearance of 40 feet above mean high water in the closed-to-navigation position and 100 feet above mean high water in the open-to-navigation position. Navigation on the waterway consists primarily of tugs with tows, commercial fishing vessels, and occasional recreational craft. Mariners may use the Gulf Intracoastal Waterway (Harvey Canal) to avoid unnecessary delays. The Coast Guard has coordinated this closure with the Gulf Intracoastal Canal Association (GICA). The GICA representative indicated that the vessel operators will be able to schedule transits through the bridge such that operations will not significantly be hindered. Thus, it has been determined that this closure will not have a significant effect on these vessels.

In accordance with 33 CFR 117.35, the draw bridge 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.
