NAME OF APPLICANT: Shintech Louisiana, LLC, c/o: Providence Engineering and Environmental Group, LLC., attn.: Ms. Regina Staten, 1201 Main Street., Baton Rouge, Louisiana 70802.

LOCATION OF WORK: Located on an approximate 494.65-acre site, located along and northwest of LA Hwy 405 (River Road), approximately 5.3 miles southeasterly of Plaquemine, in Iberville Parish, within the Terrebonne Basin in hydrologic unit (HUC 08070300), as shown on the attached drawings (Latitude 30.230837 N, Longitude -91.164814 W).   

CHARACTER OF WORK: The applicant has requested a modification to an existing Department of the Army authorization to clear, grade, excavate and deposit fill to two new petrochemical facilities to be incorporated into the existing, previously authorized Shintech Plaquemine Plant Complex (SPP), located along the west bank of the Mississippi River, near river mile 197.  The two new facilities, Shintech Plaquemine Plant-4 (SPP-4) and Plaquemine Ethylene Plant-2 (PEP-2), would be added to the existing SPP to increase production of vinyl chloride monomer, polymer grade ethylene, and other intermediate products (chlorine, caustic soda, and ethylene dichloride).  The project also proposes construction of appurtenant supporting structures such as: bulk truck loading/unloading areas, railcar loading/unloading areas, on-site utilities, steam-generating units, spherical storage tanks, and a wastewater treatment facility.  Approximately 534,700 cubic yards of clean soil fill material, 544,600 cubic yards of gravel, and 244,900 cubic yards of concrete would be hauled in limestone would be placed as fill material in jurisdictional areas.  The proposed permit modification would impact approximately 3.75 acres of jurisdictional Other Waters of the US from fill placement.  All previous wetland impacts that were associated with the original permit authorization have been mitigated for at mitigation banks. The applicant proposes to utilize best management practices for erosion and siltation control during and after the construction phase of the project. The applicant claims that the proposed project has been designed to avoid and minimize direct and secondary adverse impacts to the maximum extent practicable and has limited the new impacts associated with this project to jurisdictional Other Waters of the US.  If authorized, the project will receive approval from all appropriate local drainage authorities and sewerage agencies. Compensatory mitigation has determined to not be required at this time due to the project expansion not proposing to impact jurisdictional wetlands.
