NAME OF APPLICANT:  Boardwalk Louisiana Midstream, LLC, c/o Ramboll Engineering US Corporation, Attn: Alie Nicotera, 1055 St. Charles Avenue, Suite 501, New Orleans, Louisiana 70130  

LOCATION OF WORK:  Located on an approximate 6.5-acre site, located near Mississippi River mile 166, near Union, Louisiana, located in Saint James Parish, as shown on the enclosed drawings (Latitude 30.07925 N Longitude -90.90711 W).  This project is located in the Pontchartrain Basin (Maurepas HUC 080070204).  

CHARACTER OF WORK:  The applicant is requesting a Department of the Army permit authorization for the installation and maintenance of an approximate 4.44-mile long 8-inch ethylene pipeline to provide an alternative ethylene source to the existing Americas Styrenics production facility.  The 8-inch pipeline would be installed via Horizontal Directional Drilling (HDD) underneath the Mississippi River, near river mile 166, near Union, Louisiana, within Saint James Parish.  A spare 8-inch pipeline is also proposed to cross underneath the Mississippi River adjacent to the proposed line.  Approximately 15,512 cubic yards of native material would be excavated and backfilled during pipeline installation in the existing right-of-way.  Approximately 364 cubic yards of hauled in limestone material and 364 cubic yards of hauled in sand material would be placed onsite during the pipeline installation.  Approximately 90 cubic yards of limestone would be temporarily placed as fill during project implementation.   Approximately 1.3 acres of jurisdictional forested wetlands would be impacted as a result of the ethylene pipeline installation.  The applicant has claimed that the project has been designed to avoid and minimize direct and secondary adverse wetland impacts to the maximum extent practicable.  The applicant is proposing to utilize best management practices during and after the construction phase of the project.  The applicant is proposing to compensate for the unavoidable impact by purchasing mitigation credits from an approved mitigation bank.
