The staff of the Federal Energy Regulatory Commission (FERC or Commission) plans to prepare an environmental impact statement (EIS) that discusses the environmental impacts of the Sempra Energy LNG's and Sempra Energy International's (collectively referred to as Sempra) proposed Port Arthur LNG Project involving construction and operation of a liquefied natural gas (LNG) import terminal, natural gas pipelines and associated facilities in Jefferson County, Texas and Cameron, Calcasieu, and Beauregard Parishes, Louisiana. This EIS will be used by the Commission in its decision-making process to determine whether the project is in the public convenience and necessity.

The Port Arthur LNG is currently in the preliminary stages of design and at this time a formal application has not been filed with the Commission. For this project, the Commission is initiating the National Environmental Policy Act (NEPA) review prior to receiving the application. This allows interested stakeholders to become involved early in the project planning and to identify and resolve issues before a formal application is filed with the FERC. A docket number (PF04-11-000) has been established to place information filed by Sempra and related documents issued by the Commission, into the public record.[1] Once a formal application is filed with the FERC, a new docket number will be established.

This notice is being sent to residents within 0.5 mile of the proposed LNG terminal site; landowners along the pipeline routes under consideration; Federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American tribes; and local libraries and newspapers.

With this notice, we [2] are asking federal, state, and local agencies with jurisdiction and/or special expertise with respect to environmental issues to formally cooperate with us in the preparation of the EIS.[3] These agencies may choose to participate once they have evaluated the proposal relative to their responsibilities. Agencies which would like to request cooperating status should follow the instructions for filing comments described later in this notice. We encourage government representatives to notify their constituents of this planned project and encourage them to comment on their areas of concern.

Some affected landowners may be contacted by a project representative about the acquisition of an easement to construct, operate, and maintain the proposed pipeline. If so, the company should seek to negotiate a mutually acceptable agreement. In the event that the project is certificated by the Commission, that approval conveys the right of eminent domain for securing easements for the pipeline. Therefore, if easement negotiations fail to produce an agreement, the company could initiate condemnation proceedings in accordance with state law.

Summary of the Proposed Project

Sempra proposes to construct and operate an LNG import terminal and two natural gas pipelines to import LNG and deliver up to 1.5 billion cubic feet per day (Bcf/d) of natural gas during Phase I, increasing to 3.0 Bcf/d during Phase II, to existing intrastate and interstate pipeline systems.

The LNG terminal proposal would be located approximately 10 miles south of Port Arthur, Jefferson County, Texas and 2 miles northwest of the town of Sabine Pass. The terminal would be located on a 286-acre site along State Highway (SH) 87, immediately adjacent to the J.D. Murphree Wildlife Management Area and along the west bank of the Sabine-Neches Waterway (Port Arthur Ship Channel).

The terminal would be designed to accept LNG cargo, temporarily store and vaporize LNG, and would contain two ship berths, and up to six storage tanks, each with a net usable volume of 160,000 cubic meters (m3) or 1,006,000 barrels (each tank would be approximately 150 feet tall and 250 feet in diameter). Phase I would involve the construction of three storage tanks with an additional three tanks being added in Phase II.

The terminal would contain a dedicated slip and berths capable of accommodating the unloading of two LNG tankers. The berths would be designed for LNG tankers, such that the entire ship within the slip would be outside of the existing ship channel. One LNG tanker would visit the terminal every 2 days in the initial phase, increasing to one tanker every day in the second phase.

The pipelines would consist of two 36-inch-diameter natural gas send out pipelines to transport the vaporized natural gas to the existing interstate gas facilities. The first pipeline would consist of a 3.0-mile long pipeline from the terminal, heading south to an interconnection with the existing NGPL facilities in Jefferson County, Texas. The second pipeline would consist of a 70.0-mile long pipeline from the terminal, traveling northeast across Sabine Lake through Jefferson County, Texas and into Cameron, Calcasieu, and Beauregard Parishes, Louisiana to an interconnection with the existing Transco pipeline system.

A map depicting the proposed terminal site and the pipeline routes is provided in Appendix 1.[4]

Non-Jurisdictional Facilities

The proposed project would require the relocation of approximately 3.3 miles of SH 87 as well as existing pipelines and other utilities that parallel the highway. Sempra would relocate the highway on property that is already owned by the company.

There are five gas or oil pipelines and a water line that would also have to be relocated or abandoned. The length of each pipeline to be relocated is approximately three miles. These pipelines would be re-routed to the west of the LNG terminal along the east side of the re-located SH 87. Telephone and power lines would also be relocated concurrently with SH 87.

The proposed LNG terminal would require electrical service. Entergy would install a new 230 kilovolt (kV) interconnecting transmission line consisting of two independent 230 kV electrical transmission/distribution lines and a new substation. The proposed substation would be located on a 500 foot by 450 foot (approximately 5.17 acre) site within the LNG terminal property boundary. The new Entergy substation would provide dedicated and redundant service for the terminal. Start Printed Page 76937

Land Requirements for Construction

Construction of the proposed facilities would require approximately 190 acres for the terminal permanent facilities of which approximately 115 acres are for the marine facilities. An additional 68.5 acres of area outside of the LNG terminal would be used for temporary construction areas (laydown, office, and parking), for a total of 183.6 acres of disturbance for construction. The ship berths would require dredging to achieve the required size and depth to accommodate the LNG tanker ships.

The two pipelines would be constructed on a nominal 100-foot-wide right-of-way with occasional increases in the right-of-way width for additional workspace at waterbody, highway, and railroad crossings, and for topsoil storage. Other temporary land requirements would include land for pipe storage and equipment yards. Operation of the pipeline facilities would require a nominal 50-foot-wide permanent right-of-way.

Construction of the 3.0 mile natural gas pipeline would affect a total of 28.3 acres. Approximately 11.3 acres of the total would be retained for operation of the pipeline and aboveground facilities.

Construction of the 70.0 mile natural gas pipeline would affect a total of approximately 374.5 acres of land. Approximately 150.0 acres would be retained for operation of the pipeline and above ground facilities.

The EIS 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 or an import authorization under Section 3 of the Natural Gas Act. NEPA also requires us to discover and address concerns the public would have about proposals. This process is referred to as “scoping”. The main goal of the scoping process is to focus the analysis in the EIS on the important environmental issues and reasonable alternatives. By this Notice of Intent, the Commission staff requests agency and public comments on the scope of the issues to address in the EIS. All comments received are considered during the preparation of the EIS. State and local government representatives are encouraged to notify their constituents of this proposed action and encourage them to comment on their areas of concern.

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

  • Geology and soils
  • Land use
  • Water resources, fisheries, and wetlands
  • Cultural resources
  • Vegetation and wildlife
  • Air quality and noise
  • Endangered and threatened species
  • Hazardous waste
  • Public safety

We may also evaluate possible 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 are included in the draft EIS. Depending on the comments received during the scoping process, the draft EIS would be published and mailed to federal, state, and local agencies, Native American tribes, public interest groups, interested individuals, affected landowners, newspapers, libraries, and the Commission's official service list for this proceeding. A 45-day comment period would be allotted for review of the draft EIS. All comments on the draft EIS would be considered and the document revised before issuing a final EIS. This draft EIS is used by the Commission in its decision-making process to determine whether the project is in the public convenience and necessity.
