Environmental Compliance

Gulf South will comply with all environmental requirements including the National Environmental Policy Act (NEPA) and FERC's Upland Erosion Control, Revegetation and Maintenance Plan (Plan) and Wetland and Waterbody Construction and Mitigation Procedures (Procedures). 


NEPA requires the FERC to take into account the environmental impacts that could result from the Project and address concerns the public may have about the proposed project (aka "scoping"). The scoping process focuses the environmental analysis on the important environmental issues.  The FERC will request public comments on the scope of the issues to address in the environmental assessment of the Project. The FERC will also evaluate possible alternatives to the planned Project, and make recommendations on how to lessen or avoid impacts on the various resources.


Environmental Assessment
The FERC prepared an Environmental Assessment (EA) which discusses the environmental aspects of the Westlake Expansion Project involving construction and operation of the proposed facilities. The FERC mailed copies of the EA to federal, state, and local stakeholders and landowners. A public comment period was announced, which ended March 27, 2018, to gather input from the public and interested agencies about the Project.

Environmental Protection during Construction

Before construction begins, all construction personnel will receive environmental training focusing on their duties.  Construction activities will fully comply with the requirements and provisions of environmental permits issued and the requirements of FERC's Plan and Procedures.  Gulf South will employ environmental inspectors separate from the construction staff and contractors, who will oversee and enforce adherence to environmental requirements.  These environmental inspectors will have the authority to shut down construction if necessary, to ensure environmental compliance.
