NAME OF APPLICANT:  Mitsubishi Chemical America, Inc., c/o Providence Engineering, Attn: Regina Staten, 1201 Main Street, Baton Rouge, LA 70802.      

 LOCATION OF WORK:  In an approximate 77.03-acre site located along and southeast of LA Hwy. 30, in Section 3, Township 10 South, Range 2 East, near Geismar, Louisiana, in Ascension Parish, within the Pontchartrain Basin in hydrologic unit (HUC 08070202), as shown on the attached drawings (Latitude 30.207568 N, Longitude -90.996031 W).   

CHARACTER OF WORK: The applicant has requested Department of the Army authorization to clear, grade, excavate and deposit fill to construct and maintain an approximate 77.03-acre industrial methyl methacrylate production facility which includes access roads, construction laydown areas, drainage gulley, onsite attenuation and stormwater retention ponds, culverts, drainage infrastructure, and other appurtenances.  The project proposes to produce methyl methacrylate (MMA) which is utilized for the production of acrylic polymers, resins, and paints.  The proposed facility would operate a new 770 million lbs/annum MMA production facility with units to produce key raw materials of the applicant’s Alpha Technology process.  Approximately 523,399 of hauled in topsoil/sand material, 48,676 cubic yards of concrete, 39,647 cubic yards of limestone/gravel, 29,748 cubic yards of gravel, and 4,628 cubic yards of asphalt material would be hauled in and placed as fill material in jurisdictional areas.  Approximately 40,007 cubic yards of clean silt fill from onsite excavation would be placed as fill material in jurisdictional areas. Approximately 61.35 acres of jurisdictional forested wetlands, 7.1 acres of jurisdictional emergent wetlands, and 0.4 acre of jurisdictional scrub shrub wetlands would be directly impacted as a result of project implementation from fill placement and excavation activities.  Approximately 1.44 acres of jurisdictional Other Waters of the US (OWOUS) would be directly impacted from project implementation.  The applicant proposes to utilize best management practices for erosion and siltation control during and after the construction phase of the project.  If authorized, the project will receive approval from all appropriate local drainage authorities and sewerage agencies. The applicant has indicated on Sheets 6a-6b of the drawings a number of existing and proposed support features which have either been previously permitted, or have yet to be permitted.  The applicant claims that the proposed project has been designed to avoid and minimize direct and secondary adverse impacts to the maximum extent practicable while still achieving their goal and had selected the proposed site based on surrounding existing infrastructure and proximity to the Mississippi River.  As compensation for unavoidable wetland impacts, the applicant proposes to use a Corps approved mitigation bank within the watershed of impact.
