FERC reviews pipeline needed for coal-to-gas conversion in Tennessee

The staff of the Federal Energy Regulatory Commission has prepared an environmental assessment (EA) for the Loudon Expansion Project, proposed by East Tennessee Natural Gas LLC, and has the draft EA out for public comment until Jan. 27.

East Tennessee requests authorization to construct and operate natural gas facilities in Monroe and Loudon counties, Tennessee. The Loudon Expansion Project would provide up to 40,000 decatherms per day of natural gas to Tate & Lyle Americas Ingredients LLC, a manufacturer of artificial sweeteners and ethanol products, that is planning to convert its existing coal-fired boilers to natural gas and install a new natural gas-fueled combined cycle power plant.

The FERC 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 proposed Loudon Expansion Project includes the following facilities:

  • 10.2 miles of new 12-inch-diameter natural gas pipeline (Loudon Mainline Extension) from East Tennessee’s existing 3200 mainline in Monroe County, Tennessee, to the Tate & Lyle Plant in Loudon County, Tennessee;
  • one 12-inch mainline valve, two 12-inch tee taps, above- and below-ground piping, and a pig launcher barrel in Monroe County, Tennessee;
  • one new meter facility, above- and below-ground piping, flow measurement and control equipment, a filter/separator, a pig receiver barrel, above-ground valve operators for below-ground valves, blowdowns, and a condensate tank in Loudon County, Tennessee; and
  • a pressure regulator at the existing Meter Station 59039 on its Loudon-Lenoir City Lateral Line 3218D-100 in Loudon County, Tennessee.

The project would provide up to 40,000 Dth/d of natural gas to Tate & Lyle. Under a Feb. 13, 2015, precedent agreement, East Tennessee would provide to Tate & Lyle the natural gas service for a primary term of 20 years from the service commencement date.
