NAME OF APPLICANT:  IMTT Geismar, c/o Duplantis Design Group, PC, 16564 Brewster Road, Suite 101, Covington, LA 70433.      

LOCATION OF WORK:  In the Mississippi River, Left Descending Bank, River Mile 184, at 8122 Highway 75 in Geismar, Louisiana, Section 14, T10S-R2E of Ascension Parish within the Mississippi Basin in hydrologic unit (HUC 08070100), as shown on the attached drawings (Latitude 30.184701 N, Longitude -91.009228 W).   

CHARACTER OF WORK: The applicant has requested a modification to the Department of the Army authorization MVN-2014-00284-CG (dated September 28, 2015, modified on February 24, 2017 and extended for time July 21, 2018) to clear, grade, and deposit fill material to construct and maintain an expansion of the existing structures at the IMTT-Geismar facility to include a new 5,500 LF pipe rack, support infrastructure, and dock bridge to span Hwy 75. This project site is adjacent to and abutting the existing BASF facility (authorized as LMNOD-SP SE Mississippi River 370, MVN-1997-00005-CO). Approximately 2,780 cubic yards of fill material would be hauled in and deposited to achieve required grade elevation requirements.  The proposed project is situated on an approximately 24-acre tract.  To complete the expansion, approx. 2.75 acres of jurisdictional wetlands, 0.21 acre of waters of the US, and 0.17 acre of traditionally navigable waters would be directly impacted.

The applicant proposes to avoid additional direct impacts and minimize secondary impacts to the maximum extent practicable by avoiding 1.31 acres of wetlands and proposing only temporary impacts to approx. 1.34 acres of the wetlands impacted in the batture, by utilizing best management practices for erosion and siltation control during and after the construction phase of the project, and by limiting the construction activity to the designated construction areas onsite. As compensation for unavoidable wetland impacts, the applicant proposes to mitigate in-kind wetland credits from a Corps approved mitigation bank located in the watershed
