The Federal Energy Regulatory Commission (FERC) is the regulatory agency that oversees the U.S. interstate natural gas pipeline industry. The FERC regulates both the construction of natural gas pipeline facilities, including compressor stations, and the transportation of natural gas in interstate commerce. For more information regarding the FERC's role as a regulator of interstate natural gas transmission, visit FERC's website.

Companies such as Gulf South wishing to build compressor stations and interstate natural gas pipeline facilities must first file an Application with the FERC seeking approval.  This process ensures that the proposed pipeline facilities benefit consumers, are compatible with the environment and minimize interference with the public and landowners surrounding the compressor station or along the pipeline's right-of-way.

The FERC prepared an Environmental Assessment (EA) which evaluates environmental impacts of the Westlake Expansion Project, including the impacts of construction and operation of the proposed facilities. The FERC mailed copies of the EA to federal, state, and local government representatives and agencies; elected officials; Native American tribes; potentially affected landowners; newspapers and libraries in the project area; and, parties to the proceeding. A public comment period was announced, which ended March 27, 2018, to gather input from the public and interested agencies about the Project.

All public documents related to the Westlake Expansion Project are available through FERC's "eLibrary" website. These documents include all public correspondence from Gulf South, the FERC, landowners, and stakeholders. Documents are posted soon after being received at the FERC. To perform a search:
  • Select "General Search" and enter the docket number assigned to the project which is CP17-476
  • Update the date range field if appropriate
  • Alternatively, you can enter "Westlake Expansion Project" in the "Text Search" field instead of the docket number
