Appalachia to Market II and Armagh and Entriken HP Replacement Projects
The Appalachia to Market II and Armagh and Entriken Replacement projects are designed to provide additional firm natural gas transportation to serve utilities and help meet growing demand for reliable, affordable energy and to modernize and strengthen our infrastructure network.
The Armagh and Entriken Replacement projects support the continued safe and reliable operation of the existing Armagh and Entriken Compressor Stations by replacing existing compressor units with new, more energy-efficient units.
The projects also propose to install approximately 2 miles of new pipeline in Lebanon County, and make modifications at two existing compressor stations.
The facilities required for the projects are generally located within and adjacent to Texas Eastern’s existing right-of-way and at existing compressor stations owned and operated by Texas Eastern.
