Start Preamble January 25, 2011.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) will prepare an environmental assessment that will discuss the environmental impacts of the Choctaw Hub Expansion Project involving construction and operation of facilities by PetroLogistics Natural Gas Storage Company, LLC (PetroLogistics) in Iberville Parish, Louisiana. This EA will be used by the Commission in its decision-making process to determine whether 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 on the project. Your input will help the Commission staff determine what issues need to be evaluated in the EA. Please note that the scoping period will close on February 24, 2011.

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

If you are a landowner receiving this notice, you may be contacted by a pipeline company representative about the acquisition of an easement to construct, operate, and maintain the proposed facilities. The company would seek to negotiate a mutually acceptable agreement. However, if the project is approved by the Commission, that approval conveys with it the right of eminent domain. Therefore, if easement negotiations fail to produce an agreement, the pipeline company could initiate condemnation proceedings where compensation would be determined in accordance with State law.

A fact sheet prepared by the FERC entitled “An Interstate Natural Gas Facility On My Land? What Do I Need To Know?” was attached to the project notice PetroLogistics provided to landowners. 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 Web site (

Summary of the Proposed Project

PetroLogistics proposes to construct the Choctaw Hub Expansion Project facilities consisting of two converted salt dome caverns and new pipeline, compression and meter station interconnect facilities. These facilities would be constructed in or adjacent to PetroLogistics' existing natural gas storage and pipeline facilities located 4 miles northwest of the City of Plaquemine in Iberville Parish, Louisiana. PetroLogistics would operate these high-deliverability, multi-cycle natural gas storage facilities in order to increase the total working capacity of the Choctaw Hub from 16 billion cubic feet (bcf) to 33.9 bcf. According to PetroLogistics, this project would increase PetroLogistics' ability to provide firm and interruptible storage and hub services in the Gulf Coast region.

The Choctaw Hub Expansion Project would consist of the following facilities:

  • Conversion, into gas storage caverns, of existing Cavern No. 28, currently used for commercial brine service and existing Cavern No. 102, currently used for liquid-ethylene storage service;
  • 13-mile-long 30-inch-diameter Expansion Header Pipeline looping PetroLogistics' existing pipelines; [1]
  • two compressor units totaling 27,000 horsepower at the existing PetroLogistics Compressor Station;
  • 0.67-mile-long 30-inch-diameter cavern injection/withdrawal pipeline (30-Inch Compressor Station Pipeline) from the proposed Compressor Station Expansion to Cavern 28;
  • 0.66-mile-long 16-inch-diameter cavern injection/withdrawal pipeline extending from the 30-Inch Compressor Station pipeline at Cavern 28 to the well head at Cavern 10;
  • 300-foot-long 10-inch-diameter cavern injection/withdrawal pipeline extending from the 30-Inch Compressor Station pipeline to the existing certificated Cavern 24;
  • 0.90-mile-long 20-inch-diameter pipeline and expansion of the Texas Eastern Transmission Company Meter Station Interconnect;
  • 0.23 acre expansion of the meter station interconnect to Bridgeline Pipeline Company;
  • 0.23 acre expansion of the meter station interconnect to Southern Natural Gas Company;
  • meter station interconnects to Florida Gas Transmission Company, LLC and CrossTex LIG Pipeline Company;
  • side valves on the Expansion Header Pipeline for future lateral interconnects; and
  • 5.5 acre non-jurisdictional electrical substation and 1,460 feet of overhead conductor lines to increase the existing electrical service lines to 69 kilovolt amperes supply capability.

The general location of the project facilities is shown in appendix 1.[2]

Land Requirements for Construction

Construction of the proposed facilities would require disturbance of 131 acres of land. This total would include 65 acres under existing permanent easement right-of-way, 17 acres to be added as new permanent easement (and ownership of aboveground facilities), and 49 acres as temporary construction Start Printed Page 5579right-of-way that would be restored to previous land use following construction. PetroLogistics would use a 75-foot-wide construction right-of-way with a 10 to 40-foot temporary right-of-way width for the installed pipeline. About 45 percent of the proposed pipelines would parallel existing pipeline, utility, or road rights-of-way.

The EA Process

The National Environmental Policy Act (NEPA) requires the Commission to take into account the environmental impacts that could result from an action whenever it considers the issuance of a Certificate of Public Convenience and Necessity. NEPA also requires us [3] to discover and address 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 the issues to address in the EA. All comments received will be considered during the preparation of the EA.

In the EA we 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,
  • Wetlands and fisheries,
  • Vegetation and wildlife, including migratory birds,
  • Threatened and endangered species,
  • Land use,
  • Cultural resources,
  • Air quality and noise,
  • Reliability and safety, and
  • Cumulative impacts.

We 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.

Our independent analysis of the issues will be presented in the EA. The EA will be placed in the public record and, depending on the comments received during the scoping process, may be published and distributed to the public. A comment period will be allotted if the EA is published for review. We will consider all comments on the EA before we make our recommendations to the Commission. To ensure your comments are considered, please carefully follow the instructions in the Public Participation section below.

With this notice, we are asking agencies with jurisdiction and/or special expertise with respect to environmental issues to formally cooperate with us in the preparation of the EA. These agencies may choose to participate once they have evaluated the proposal relative to their responsibilities. 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.
