FERC to do enviro review on Tennessee Gas abandonment/addition project

The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the abandonment of facilities by Tennessee Gas Pipeline Co. LLC and the addition of other facilities.

The commission 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 the commission take input on what should be covered by the EA will close on May 18.

FERC said in an April 17 notice that Tennessee proposes to abandon in place and remove from service approximately 964 miles of its existing pipelines that run from Natchitoches Parish, La., to Columbiana County, Ohio. Tennessee currently operates six parallel pipelines that transport natural gas from the Gulf of Mexico region to the Northeast markets. The proposed project would occur on Tennessee’s existing 100 and 200 Lines.

In order to replace capacity that would be lost due to the abandonment, Tennessee would modify and construct certain facilities along the existing pipelines not proposed for abandonment. Tennessee would abandon in place the following facilities:

  • 677 miles of Tennessee’s 24-inch-diameter 100-1 Line from Compressor Station 40 in Natchitoches Parish, Louisiana, to Compressor Station 106 in Powel County, Kentucky;
  • 77 miles of Tennessee’s 26-inch-diameter 100-3 Line from Compressor Station 106 to Compressor Station 200 in Greenup County, Kentucky; and
  • 210 miles of Tennessee’s 26-inch-diameter 200-3 Line from Compressor Station 200 to MLV 216 in Columbiana County, Ohio, including disconnection of the 200-3 Line from an aerial crossing at either side of the Ohio River headers.

Tennessee would construct and install the following facilities:

  • an additional 10,771 horsepower (hp) compressor unit at Compressor Station 875, to be constructed by Tennessee as part of the Broad Run Expansion Project in Madison County, Kentucky;
  • two compressor units at Tennessee’s existing Compressor Station 110 in Rowan County, Kentucky, adding 32,000 hp;
  • four new mid-point compressor stations, (Compressor Stations 202.5, 206.5, 211.5, and 216.5), on lines 200-1, 200-2, and 200-4, adding a total of 82,000 hp in Jackson, Morgan, Tuscarawas, and Mahoning counties, Ohio;
  • a 7.6-mile-long new pipeline loop in Carter and Lewis Counties, Kentucky to continue Tennessee’s Line 100-7; and
  • removal of certain crossovers, taps, valves and miscellaneous pipe, and the relocation and/or installation of new taps to complete the physical separation of the Abandoned Line from Tennessee’s retained pipelines.

Following the abandonment of Tennessee’s pipeline facilities, Tennessee indicates that it would complete necessary work to disconnect and transfer the Abandoned Line and associated facilities to Utica Marcellus Texas Pipeline LLC (UMTP) which would convert the Abandoned Line to natural gas liquids (NGL) products transportation service (UMTP Project). These future activities are not under the FERC’s jurisdiction, and therefore, are not subject to the FERC’s review procedures under this EA.
