NAME OF APPLICANT: Clean Hydrogen Works, c/o CK Associates, Attn: Ms. Olivia Barry, 8591 United Plaza Blvd., Suite 300, Baton Rouge, Louisiana 70809.
LOCATION OF WORK: On an approximate 1,700-acre site, located within and along the right descending bank of the Mississippi River, near river mile 180, located at 5323 LA Highway 405, near Donaldsonville, in Ascension Parish, Louisiana, (lat. 30.143889, long. -91.038056), as shown within the attached drawings. (Hydrologic Unit Code 08090302, Lower Mississippi River Basin, West Central Coastal Louisiana Watershed).
CHARACTER OF WORK: The applicant is proposing to clear, grade, place and maintain fill material for the construction of an industrial hydrogen/ammonia facility which includes a heavy haul road, marine terminal, and associated infrastructure. The project will utilize a natural gas pipeline to feed up to six ammonia trains each with a 3,600 metric tons per day capacity. The proposed project targets to capture approximately 98% of the generated carbon dioxide exporting it via pipeline and storing it in subterranean formations. The generated ammonia is being proposed to be exported via a new marine terminal to provide end market applications of marine fuel, power, fertilizer, and hydrogen generation. The proposed project is designed to generate 21,600 metric tons per day of liquid ammonia. The product ammonia is proposed to be stored onsite tankage for ship export and the carbon dioxide produced with be compressed and fed into the nearby Denbury pipeline. The project proposes to impact approximately 53.9 acres of Mississippi River waterbottoms via dredging for marine terminal construction. The dredged waterbottoms would be disposed below the -55-foot contour within the Mississippi River downstream of the project site. The project proposes to directly approximately 15.61 acres of Mississippi River batture forested jurisdicitonal wetlands, and 30.8 acres of jurisdictional Other Waters of the US (Mississippi River and protected side waters). Approximately 68,000 cubic yards of hauled in material would be placed as fill in jurisdictional areas for the heavy haul and pipe rack installation, 31,000 cubic yards of steel piles placed in jurisdictional areas for the proposed marine terminal installation, and 2,500 cubic yards of fill material for the proposed facility. Approximately 2,615,000 of native material in the Mississippi River and 150,000 cubic yards of native material from the batture area would be excavated for the proposed marine terminal construction. Approximately 100,000 cubic yards of native material from the protected side of the levee would be excavated from jurisdictional areas for the proposed facility and its associated infrastructure.
MITIGATION: The applicant proposes to avoid direct impacts and minimize secondary impacts to wetlands to the maximum extent practicable. The applicant is proposing to avoid approximately 501.94 acres of jurisdictional wetlands located on the protected side of the project area, 171.54 acres of jurisdictional Mississippi River batture forested wetlands, and 39.5 acres of jurisdictional Other Waters of the US. For compensation for unavoidable wetland impacts, the applicant proposes to use a Corps approved mitigation bank within the watershed of impact.
