NAME OF APPLICANT: TAMINCO US LLC. , c/o CK Associates, 8591 United Plaza Boulevard, Suite 300, Baton Rouge, Louisiana 70809.

LOCATION OF WORK: At 3790 Highway 30, St. Gabriel, Louisiana, Latitude 30.248169° N, Longitude -91.091111° W in Iberville Parish, within the Lake Pontchartrain Basin in hydrologic unit (HUC 08070202), as shown on the attached drawings.

CHARACTER OF WORK: The applicant has requested a Department of the Army authorization to clear, grade, excavate and deposit fill and/or aggregate material in wetlands and other waters of the United States for the construction of additional rail tracks and culverts and drainage connections in the expansion of an existing railway. Approximately 5,836 and 5,697 cubic yards of ballast and sand material, respectively, would be hauled in and deposited to achieve required grade elevation requirements. Additionally 431 cubic yards of native fill would be deposited to achieve required grade elevation requirements.

A preliminary analysis has determined that the proposed project would permanently impact approximately 3.05 acres of emergent wetlands and 0.12 acre of other waters of the United States. It is anticipated that the proposed action would have minimal impact on adjacent wetlands.

The applicant is claiming the proposed project will minimize wetland impacts to the greatest extent practicable by siting the rail spur immediately adjacent to the existing railyard and maximizing non-wetlands areas as depicted on the existing jurisdictional determination. Construction laydown and material staging for the project are to be limited to uplands within the existing facility footprint.

As compensation for unavoidable wetland impacts the applicant proposes to purchase 3.05 acres of in-kind wetland credits from a Corps approved mitigation bank located in the watershed.
