Start Preamble November 13, 2006.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared an environmental assessment (EA) on the natural gas facilities proposed by Trunkline LNG Company, LLC (Trunkline LNG) in the above-referenced docket.

The EA was prepared to satisfy the requirements of the National Environmental Policy Act. The staff concludes that approval of the proposed project, with appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment.

The EA assesses the potential environmental effects of the construction and operation of Ambient Air Vaporization (AAV) facilities at its existing liquefied natural gas import terminal in Calcasieu Parish, Louisiana. These facilities would consist of system that uses ambient heat in the air to reduce the use of fuel gas in the vaporization of liquefied natural gas (LNG). Additionally, Trunkline LNG would add natural gas liquids (NGL) processing facilities for LNG conditioning and British thermal unit (Btu) control. The facilities would include the following:

  • 64 Potassium Formate (KF)-Air heaters (64 forced convection, three-fan air exchangers, 17.9 million Btu per hour (MMBtu/hr)/Air Heater;
  • Four KF-LNG Vaporizers (525 million standard cubic feet per day [MMscf/d]);
  • One NGL Recovery Unit, sized for a maximum capacity of 1,050 MMscf/d;
  • 1,160 feet of 12-inch-diameter ethane product piping;
  • 1,160 feet of 12-inch-diameter propane product piping;
  • Two propylene glycol heaters (150 MMBtu/hr each);
  • Glycol storage and circulation System;
  • Two electrical switchgear buildings;
  • One remote instrumentation building, designed as Equipment Room 2; and
  • Foam Building No. 4.

The EA also discusses facilities planned by British Gas (BG), and Entergy Louisiana which are considered nonjurisdictional facilities to the FERC. These facilities include the expansion of the existing electric substation, a meter station, and the construction of two 16.4 mile-long (each) take away NGL product pipelines; an NGL processing facility consisting of a metering station and a depropanizer/truck terminal facility; and an underground storage cavern. BG has contracted PetoLogistics, LLC to design, permit, and operate the meter station and take away pipelines. The pipelines would consist of a 12-inch-diameter ethane (approximately 1,800 gallons per minute [gpm]) pipeline and an 8-inch-diameter propane (approximately 1,250 gpm) pipeline. The pipelines would be constructed from the meter station to PetroLogistics' storage facility in Sulfur, Louisiana.

The EA has been placed in the public files of the FERC. A limited number of copies of the EA are available for distribution and public inspection at: Federal Energy Regulatory Commission, Public Reference Room, 888 First Street, NE., Room 2A, Washington, DC 20426, (202) 502-8371.
