NAME OF APPLICANT:  CF Industries Nitrogen, LLC, c/o Matrix New World Engineering, 4451 Bluebonnet Boulevard, suite E, Baton Rouge, Louisiana 70809. 

LOCATION OF WORK:  Within the Mississippi River Basin, in the Lower Mississippi River Baton Rouge hydrologic unit (HUC 08070100), in the Mississippi River, right descending bank, mile 173.5, near Donaldsonville, Louisiana, in Ascension Parish. 

CHARACTER OF WORK:  The applicant proposes to modify the dredge area currently authorized by permit dated September 3, 1965, and subsequent modifications dated August 25, 2006, and May 1, 2012. The dredge channel will be increased by approximately 0.275 acre. Currently, restrictions have been placed on some ships leaving the applicant’s facility. It is anticipated that maintaining the additional area to a depth of -45 feet NGVD will allow these restrictions to be lifted.  A total of 300,000 cubic yards of accumulated river silt will be removed during the routine maintenance dredging event and deposited in the Mississippi River below the -55’ contour. All work will take place from the waterway from a hydraulic dredge. No vegetated wetlands will be impacted by the proposed work.   

According to the applicant, they have designed the proposed additional dredge area to minimize environmental impacts to the maximum extent practicable.  The maximum width of the proposed dredge area is 52 feet; the maximum length of the proposed dredge area is 469 feet.  This area represents the smallest addition of the previous authorized channel required to lift restrictions on vessel traffic from the docks.  Additionally, all dredged material will be placed below the -55’ contour and will not shoal the navigation channel of the Mississippi River.
