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

LOCATION OF WORK: In an approximate previously authorized 849.84-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 30.238053 N, Longitude -91.160229 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 construct access roads, parking areas, utility pipelines, rail storage yard, and other appurtenant structures to modify the existing SPP-1 and SPP-3 Shintech facilities. Approximately 106,500 cubic yards of clean hauled in dirt fill and 164,800 cubic yards of hauled in limestone material, would be placed as fill material in jurisdictional areas. The proposed permit modification would impact approximately 0.24 acre of jurisdictional herbaceous wetlands from fill placement. All previous wetland impacts have been mitigated for from the original permit authorization. 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 low quality wet pasture wetland habitat and is not proposing any additional impacts to forested wetlands not previously mitigated for from previous permit actions. If authorized, the project will receive approval from all appropriate local drainage authorities and sewerage agencies. As compensation for unavoidable wetland impacts, the applicant proposes to use a Corps approved mitigation bank within the watershed of impact.
