NAME OF APPLICANT: Air Liquide Large Industries, U.S. L.P., c/o Broken Arrow Consulting, LLC, attn.: Mr. Dennis McAfee, 27910 FM 149, Richards, Texas 77873.

LOCATION OF WORK: Located just North of Louisiana Highway3127 (LA-3127), the proposed route begins near St. James, Louisiana and generally follows LA-3127 within existing utility corridors and terminates at an existing facility in Taft, Louisiana, running through St. James, St. John the Baptist, and St. Charles Parishes, Louisiana, (lat. 29.980714, long. -90.872825) as shown within the attached drawings. (Hydrologic Unit Code 08090301, East Central Louisiana Coastal Watershed).

CHARACTER OF WORK: The proposed project is to construct and operate the Moonshine Mainline Pipeline Project. Construction of the pipelines would include clearing, grading, excavation, and fill deposition activities for one 20-inch oxygen pipeline and one 20-inch nitrogen pipeline in the same right-of-way for approximately 30 miles in length and up to 100 feet in width with existing utility corridors. The proposed work would be accomplished by using mechanical trenching in combination with a Push/Pull technique to be utilized in saturated/inundated wetland areas within previously cleared locations with no additional clearing; and horizontal directional drilling which is expected to be used at large forested wetland locations to avoid clearing activities. The purpose of the proposed project is to provide transport of oxygen and nitrogen via pipeline for energy use. The project as proposed would temporarily impact approximately 29.33 acres of waterbottoms and it is anticipated that there would also be temporary impacts to approximately 245.90 acres of jurisdictional wetlands from the trenching and burial of the two pipelines.
