MVN 2016-1526-CQ

Published Aug. 28, 2017
Expiration date: 9/16/2017

NAME OF APPLICANT:  Shintech Louisiana, LLC, c/o Providence Engineering, Attn: Paul Clifton, 1201 Main Street, Baton Rouge, Louisiana 70802  

LOCATION OF WORK:  Located on an approximate 817.42-acre site, located approximately 3.9 miles southeast of Plaquemine, Louisiana, located in Iberville Parish, as shown on the enclosed drawings (Latitude 30.238053 N Longitude -91.1602297 W).  This project is located in the Terrebonne Basin (Lower Grand HUC 08070300).  

CHARACTER OF WORK:  The applicant is requesting a Department of the Army permit authorization for the construction of the new Shintech Plaquemine Plant-3 (SPP-3) and expansion/modification of the existing Shintech Plaquemine Plant-1 (SPP-1).  Both facilities would be integrated into the Shintech Plaquemine Plant Complex on the west bank of the Mississippi River, near Plaquemine, Iberville Parish, Louisiana.  SPP-3 is a proposed manufacturing facility that would produce vinyl chloride monomer (VCM) and other intermediate products such as chlorine (caustic soda as a byproduct of chlorine production) and ethylene dichloride.  Purified VCM is then sent to SPP-1 or shipped to produce polyvinyl chloride (PVC).  SPP-3 also would contain a hydrochloric acid production unit.  The proposed modification of SPP-1 would allow for the expansion of the PVC facility production.  With this project’s implementation, the PVC production would increase from 1,400 million pounds per year to 2,215 million pounds per year. This project also proposes the installation and maintenance of an approximate 11.5-mile long 20-inch diameter brine pipeline extending from the existing White Castle Oil and Gas facility to the Shintech Plaquemine Plant Complex.  Approximately 76,581 cubic yards of native material would be placed in jurisdictional areas during the brine pipeline installation.  Approximately 466,065 cubic yards of hauled in gravel/ballast material and 470,510 cubic yards of hauled in native soil fill material would be placed onsite in jurisdictional areas during the facility construction phase of this project.  Approximately 34.9 acres of potentially jurisdictional herbaceous wetlands and 1.82 acres of potentially jurisdictional Other Waters of the United States (OWOUS) would be temporarily impacted as a result of the brine pipeline installation.  Approximately 6.72 acres of potentially jurisdictional forested wetlands and 0.93 acre of potentially jurisdictional scrub-shrub wetlands would be permanently converted to herbaceous wetlands during the pipeline installation process.  Approximately 6.52 acres of jurisdictional herbaceous wetlands, 10.47 acres of forested wetlands, and 0.22 acre of OWOUS would be permanently impacted via fill placement during the facility construction and expansion portions of this project. 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.  A jurisdictional determination for the brine pipeline project area is currently pending in the Corps’ Surveillance and Enforcement Section.  If additional jurisdictional impacts are determined as a result of this determination, an addendum to this Public Notice shall be required.  The applicant is proposing to compensate for the unavoidable impact by purchasing mitigation credits from an approved mitigation bank.
