NAME OF APPLICANT: Occidental Chemical Corporation, LLC (OxyChem), c/o Project Consulting Services, Inc., 1347 North Causeway Blvd, Suite 201, Mandeville, La 70471.
LOCATION OF WORK: The project is to take place between the OxyChem Convent and Geismar Facilities. The lines will exit OxyChem’s Convent Plant in St. James Parish, 30.0594, -90.8283. The co-located lines will traverse northwesterly 16.18 miles to a point approximately 0.75 miles southeast of the Geismar Facility, 30.1749, -90.9710; where the lines will diverge. The 6-Inch line and fiber optic cables will terminate at a POE, 30.1853, -90.9769, located within OxyChem’s Geismar Plant in Ascension Parish. The 8-Inch line will terminate at a POE, 30.1856, -90.9857 also located within the Geismar Plant, as shown on the attached drawings. The project area is located within the Lake Maurepas sub-basin (HUC 08070204).
CHARACTER OF WORK: The applicant has requested Department of Army authorization to construct, install, maintain and operate new pipelines in order to transport products, chlorine and ethylene dichloride, between the OxyChem Convent and Geismar Facilities. Specifically, the applicant has requested authorization to clear, grade, excavate, and temporary place fill to construct approximately 17.01 miles of 6-Inch chlorine pipeline and fiber optic cables, and approximately 17.36 miles of 8-Inch pipeline, in St. James and Ascension parishes. The proposed project will require approximately 113,254 cubic yards of excavation and temporary fill material to be placed in wetlands. Following construction, areas temporarily impacted by the project will be restored to pre-construction grade to the maximum extent practicable and allowed to revegetate. Project implementation would affect approximately 21.11 acres of PEM (herbaceous) wetlands, 1.70 acres of PSS (scrub-shrub) wetlands, and 37.72 acres of PFO1 (bottomland hardwood) wetlands, and 22.36 acres of PFO2 (swamp) wetlands. There will be a permanent conversion of approximately 0.19 acres of PSS (scrub-shrub) wetlands, 14.81 acres of PFO1 (bottomland hardwood) wetlands, and 8.90 acres of PFO2 (swamp) wetlands. Finally, as proposed the project will not result in any permanent loss of wetlands.
