Name of Applicant: Bayou Bridge Pipeline, LLC c/o Perennial Environmental Services, LLC, Attn: Marshall Olson, 13100 Northwest Freeway, Suite 150, Houston, Texas 77040
Location of Work: The proposed 162.52-mile pipeline project is located in Calcasieu, Jefferson Davis, Acadia, Vermilion, Lafayette, Iberia, St. Martin, Iberville, Ascension, Assumption, and St. James parishes Louisiana. The two proposed pump stations are located in Jefferson Davis and St. Martin parishes. The project is located in the following eight watersheds: Lower Calcasieu (08080206), Mermentau (08080202), Vermilion (08080103), Bayou Teche (08080102), Atchafalaya (08080101), Lower Grand (08070300), West Central Louisiana Coastal (08090302), and East Central Louisiana Coastal (08090301) as shown in the attached drawings.
CHaracter of Work: The applicant has requested Department of the Army authorization to install and operate a 24-inch diameter crude oil pipeline approximately 162.52 miles in length. The pipeline facilities include the proposed 161.40 mainline section beginning south of Lake Charles, Louisiana and terminating near St. James, Louisiana, as well as a proposed 1.12-mile lateral pipeline that would commence at the terminus of the mainline. The project also involves the construction of two pump stations and other ancillary facilities along the pipeline. The project activities include clearing the right-of-way, conducting trenching operations, installing various above and below ground pipelines and components, installing aboveground facilities, temporarily stockpiling materials, and performing horizontal directional drilling (HDD) operations. Following construction, areas temporarily impacted by the project will be restored to pre-construction grade and allowed to revegetate to the extent allowed under United States Department of Transportation (USDOT) regulations.
The proposed project will temporarily impact approximately 453.96 acres of jurisdictional wetlands and 42.14 acres of other waters of the U.S. In addition, approximately 158.80 acres of jurisdictional wetlands will be permanently converted to non-forested wetlands within the pipeline right-of-way. The project will result in the loss of 0.03 acre of wetlands and 0.03 acre of other waters of the U.S. as the result of the installation of culverts along permanent access roads. The installation of culverts will result in the placement of 21.50 cubic yards of fill material (clean fill/rock material and concrete culverts) in wetlands and 36.22 cubic yards of fill material in other waters of the U.S. Construction of the two pump stations and other ancillary facilities located along the pipeline will not result in the placement of fill in jurisdictional wetlands or other waters of the U.S.
The applicant has designed the project to avoid and minimize direct and secondary adverse impacts to the maximum extent practicable by co-locating the proposed route with existing rights-of-way, utilizing HDDs, reducing the construction footprint to 75 feet in wetlands, and maximizing the use of existing access roads. The applicant proposes to offset unavoidable wetland impacts by purchasing mitigation credits from Corps-approved mitigation banks within the New Orleans District.
