Start Preamble

The staff of the Federal Energy Regulatory Commission (FERC or Commission) will prepare an environmental assessment (EA) that will discuss the environmental impacts of the Evangeline Pass Expansion Project involving construction and operation of facilities by Tennessee Gas Pipeline Company, LLC (Tennessee) and Southern Natural Gas Company, LLC (SNG) in Clarke and Smith Counties, Mississippi and St. Bernard and Plaquemines Parishes, Louisiana.[1] The Commission will use this EA in its decision-making process to determine Start Printed Page 17051whether the project is in the public convenience and necessity.

This notice announces the opening of the scoping process the Commission will use to gather input from the public and interested agencies about issues regarding the project. The National Environmental Policy Act (NEPA) requires the Commission to take into account the environmental impacts that could result from its action whenever it considers the issuance of a Certificate of Public Convenience and Necessity. NEPA also requires the Commission to discover concerns the public may have about proposals. This process is referred to as scoping. The main goal of the scoping process is to focus the analysis in the EA on the important environmental issues. By this notice, the Commission requests public comments on the scope of issues to address in the EA. To ensure that your comments are timely and properly recorded, please submit your comments so that the Commission receives them in Washington, DC on or before 5:00 p.m. Eastern Time on April 20, 2020.

You can make a difference by submitting your specific comments or concerns about the project. Your comments should focus on the potential environmental effects, reasonable alternatives, and measures to avoid or lessen environmental impacts. Your input will help the Commission staff determine what issues they need to evaluate in the EA. Commission staff will consider all filed comments during the preparation of the EA.

If you sent comments on this project to the Commission before the opening of this docket on February 7, 2020, you will need to file those comments in Docket No. CP20-50-000 or CP20-51-000 to ensure they are considered as part of this proceeding.

This notice is being sent to the Commission's current environmental mailing list for this project. State and local government representatives should notify their constituents of this proposed project and encourage them to comment on their areas of concern.

If you are a landowner receiving this notice, a pipeline company representative may contact you about the acquisition of an easement to construct, operate, and maintain the proposed facilities. The company would seek to negotiate a mutually acceptable easement agreement. You are not required to enter into an agreement. However, if the Commission approves the project, that approval conveys with it the right of eminent domain. Therefore, if you and the company do not reach an easement agreement, the pipeline company could initiate condemnation proceedings in court. In such instances, compensation would be determined by a judge in accordance with state law.

Tennessee and SNG provided landowners with a fact sheet prepared by the FERC entitled “An Interstate Natural Gas Facility On My Land? What Do I Need To Know?” This fact sheet addresses a number of typically asked questions, including the use of eminent domain and how to participate in the Commission's proceedings. It is also available for viewing on the FERC website ( at​resources/​guides/​gas/​gas.pdf.

Summary of the Proposed Project

Tennessee proposes to construct and operate approximately 13 miles total of looping [3] pipeline and a new compressor station in St. Bernard and Plaquemines Parishes Louisiana. SNG proposes to construct a new compressor station and three new meter stations in Clarke and Smith Counties, Mississippi and St. Bernard Parish, Louisiana.

Tennessee has entered into an agreement with SNG to acquire leased capacity on SNG's system to enable Tennessee to provide firm transportation service up to 1,100 million standard cubic feet of natural gas per day to the recently approved Venture Global Gator Express Pipeline interconnect for feed gas for the Plaquemines LNG Terminal in Plaquemines Parish, Louisiana.

The Evangeline Pass Expansion Project would consist of the following facilities:


  • Construction of about 9 miles of 36-inch-diameter looping pipeline in St. Bernard Parish, Louisiana (Yscloskey Toca Lateral Loop);
  • construction of about 4 miles of 36-inch-diameter looping pipeline in Plaquemines Parish, Louisiana (Grand Bayou Loop);
  • construction of a new 23,470 horsepower (hp) compressor station along Tennessee's existing 500 line in St. Bernard Parish, Louisiana (Compressor Station 529);
  • replacement of two 10,410 hp units (like-for-like) under section 2.55(b) at existing Compressor Station 527 in Plaquemines Parish, Louisiana;


  • Construction of a new 22,220 hp compressor station in Clarke County, Mississippi (Rose Hill Compressor Station);
  • construction of three new meter stations in Clarke and Smith Counties, Start Printed Page 17052Mississippi and St. Bernard Parish, Louisiana (Rose Hill and Midcontinent Express Pipeline Receipt Meter Stations, and Toca Delivery Meter Station); and
  • construction and/or modification of certain system auxiliary and appurtenant facilities under section 2.55(a) at existing compressor stations and along the pipeline corridor in Clarke, Smith, Jasper, Simpson, Jefferson Davis, Lawrence, and Walthall Counties, Mississippi and St. Bernard, Washington, St. Tammany, and Orleans Parishes, Louisiana.

The general location of the project facilities is shown in appendix 2.

Land Requirements for Construction

Construction of the proposed facilities would disturb a total of about 535 acres of land for the aboveground facilities and the pipelines (including activities proposed to be conducted under section 2.55). Following construction, a total of about 133 acres of new permanent right-of-way would be maintained for permanent operation of the project's facilities; the remaining acreage would be restored and revert to former uses. The proposed looping pipeline routes would parallel existing pipelines, and to the extent that it is practicable, would be located within and adjacent to the existing rights-of-way. The new Compressor Station 529 would be located at an existing abandoned compressor station site owned by Tennessee, while SNG's new Rose Hill Compressor Station would be located within a forested timber property. Tennessee would use four contractor yards (about 27 acres total) to facilitate construction (Toca Yard, Bayou Road Yard, State Road LA-46 Yard, and Yscloskey Yard).

The EA Process

The EA will discuss impacts that could occur as a result of the construction and operation of the proposed project under these general headings:

  • Geology and soils;
  • water resources and wetlands;
  • vegetation and wildlife;
  • threatened and endangered species;
  • cultural resources;
  • socioeconomics;
  • land use;
  • air quality and noise;
  • public safety; and
  • cumulative impacts.

Commission staff will also evaluate reasonable alternatives to the proposed project or portions of the project and make recommendations on how to lessen or avoid impacts on the various resource areas.

The EA will present Commission staffs' independent analysis of the issues. The EA will be available in electronic format in the public record through eLibrary [4] and the Commission's website (​industries/​gas/​enviro/​eis.asp). If eSubscribed, you will receive instant email notification when the EA is issued. The EA may be issued for an allotted public comment period. Commission staff will consider all comments on the EA before making recommendations to the Commission. To ensure Commission staff have the opportunity to address your comments, please carefully follow the instructions in the Public Participation section, beginning on page 2.

With this notice, the Commission is asking agencies with jurisdiction by law and/or special expertise with respect to the environmental issues of this project to formally cooperate in the preparation of the EA.[5] Agencies that would like to request cooperating agency status should follow the instructions for filing comments provided under the Public Participation section of this notice.

Consultation Under Section 106 of the National Historic Preservation Act

In accordance with the Advisory Council on Historic Preservation's implementing regulations for section 106 of the National Historic Preservation Act, the Commission is using this notice to initiate consultation with the applicable State Historic Preservation Offices, and to solicit their views and those of other government agencies, interested Indian tribes, and the public on the project's potential effects on historic properties.[6] The EA for this project will document findings on the impacts on historic properties and summarize the status of consultations under section 106.

Currently Identified Environmental Issues

Commission staff have already identified several issues that deserve attention based on a preliminary review of the proposed facilities and the environmental information provided by Tennessee and SNG. This preliminary list of issues may change based on your comments and our analysis.

  • Wetlands and waterbodies;
  • fisheries and aquatic species;
  • hunting and fishing;
  • property values; and
  • air and noise.
