The Tennessee Gas Pipeline is one of the El Paso Corporation’s five interstate gas pipelines. It is approximately 14,200 miles long and stretches from the Mexican border to Canada.

An October, 2008 report qualified the above by saying the pipeline is actually 13,700 miles long and goes from the shoreline of Texas and Louisiana up through Appalachia, across northern Pennsylvania and southern New York, into the New York metro area, and on into eastern Massachusetts.

It dates back to the 1950s and is currently undergoing a $750 million expansion by the addition of a second, larger-diameter pipeline mostly using the same right of way as the earlier line uses. The expansion project is called the he 300 Line Expansion Project (TGP300 Line Expansion). It consists of laying 128 miles of new 30" pipeline to replace the existing 24" branch beginning in Potter County, in north-central Pennsylvania leading on through Tioga, Bradford, Susquehanna, Wayne and Pike counties, and across the New Jersey counties of Sussex and Passaic. It cuts right across the region of Pennsylvania that is expected to be most prolific for Marcellus shale production. The first phase of the expansion is planned to be up and running by November, 2011.

The new pipeline will carry gas produced by Equitable Energy. It will also transmit gas from drilling companies involved in Marcellus shale development.
