The following site illustrates how close they are to a pipeline.

With 1,432 miles of pipeline, East Tennessee can deliver 1.3 billion cubic feet of gas per day to meet the growing energy demands of the Southeast and Mid-Atlantic. The system begins in Tennessee and extends to an area just south of Roanoke, Virginia. A segment of the system extends into southwest Virginia and northern North Carolina through a 95-mile natural gas pipeline that interconnects with the Transco system near Eden, N.C. East Tennessee also interconnects with Texas Eastern, Tennessee Gas Pipeline, Columbia Gulf, Southern Natural Gas, and Midwestern Gas Transmission (later in 2007).

On System Storage

Connected to East Tennessee Natural Gas are several storage facilities that provide direct access to diverse storage options. Located near Kingsport, Tennessee, East Tennessee’s liquefied natural gas (LNG) storage facility provides about 11 percent of East Tennessee’s peak day requirements. The Saltville and Early Grove storage facilities provide high deliverability and depleted reservoir storage to the East Tennessee Natural Gas system in Southwest Virginia, and are wholly owned and operated by Spectra Energy.

On System Supply

In addition to interconnects with major interstate pipelines and on-system storage, East Tennessee Natural Gas provides direct access to natural gas producers in the Appalachian region through numerous connections on its mainline as well as its Nora and Jewell Ridge laterals.
