FERC readies enviro review on gas pipeline to support coal-to-gas conversion

The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the Loudon Expansion Project, which involves construction and operation of facilities by East Tennessee Natural Gas LLC in Monroe and Loudon counties, Tennessee.

The commission said in a March 24 notice that it will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. The scoping period where it will take input on what should in the EA will close on April 23.

East Tennessee would construct, own, and operate a new pipeline and related appurtenant facilities extending from its existing 12-inch-diameter Line 3200-1 pipeline in Monroe County, Tennessee, to Tate & Lyle Americas Ingredients LLC, a manufacturer of artificial sweeteners and ethanol products in Loudon County. The Loudon Expansion Project would provide up to 40,000 decatherms per day of natural gas to Tate & Lyle, which is planning to convert its existing coal-fired boilers to natural gas, and install a new natural gas-fueled combined-cycle power plant.

The Loudon Expansion Project would consist of:

  • about 10 miles of 12-inch-diameter pipeline (Loudon Mainline Extension) in Monroe and Loudon counties;
  • a new 12-inch mainline valve, two 12-inch tee taps and related appurtenant facilities at the interconnection of the Loudon Mainline Extension with the existing Line 3200-1 mainline in Monroe County;
  • a new meter facility and related appurtenances located at the end of the Loudon Mainline Extension at the Tate & Lyle Plant in Loudon County;
  • above- and below-ground piping, flow measurement equipment, flow control equipment, filter/separator, pig launcher and receiver, above-ground valve operators for below-ground valves, blowdowns, and a condensate tank; and
  • a new pressure regulator at existing meter station 59039 on East Tennessee’s existing Loudon-Lenoir City Lateral Line 3218D-100, in Loudon County.
