NAME OF APPLICANT:  Linde, Inc. c/o CK Associates, 8591 United Plaza Blvd., Suite 300, Baton Rouge, LA 70809.

LOCATION OF WORK:  In the Mississippi River at RM 185, left descending bank, in Section 50, Township 9 South, Range 2 East and Sections 3 & 11, Township 10 South, Range 2 East, on LA Highway 30 in Geismar, Louisiana, in Ascension Parish, within the Pontchartrain and Mississippi River Basins in hydrologic units (HUC 08070204 and 08070100), as shown on the attached drawings (Latitude 30.21119 N, Longitude -91.003002 W).

CHARACTER OF WORK: The applicant has requested Department of the Army authorization to clear, grade, excavate and deposit fill and/or aggregate material to construct and maintain an air separation unit complex (Linde Geismar ASU Utility Island) to include parking lots, utilities, a water intake structure, clarifiers, pipelines, and appurtenant support structures.  Approximately 28,600 cubic yards of material would be excavated and backfilled to install the pipelines and approx. 10,425 cubic yards of fill material will be hauled in to achieve required grade elevation requirements.  The proposed project is situated on an approximately 81.2 acres that has been determined to contain forested and emergent wetlands and waters of the US.  Of this, approximately 49.3 acres of wetlands and approx. 4.52 acres of waters of the US would be directly impacted in construction of the facility. 

The applicant proposes to avoid additional direct impacts and minimize secondary impacts to the maximum extent practicable by avoiding 13.26 acres of jurisdictional aquatic resources, limiting the construction activity to the designated construction areas onsite, disposing of all cleared vegetation from the pipeline construction workspace by chipping to be spread within the pipeline construction workspaces not to exceed a depth of 2-inches, and utilizing best management practices for erosion and siltation control during and after the construction phase of the project. As compensation for unavoidable wetland impacts, the applicant proposes to use a Corps approved mitigation bank within the watershed of impact.
