Spectra Energy and Conocophillips have proposed a joint expansion project called the TEMAX Project that would add 33 miles of pipeline to the system, stretching from Clarington, Ohio to Delta, Pennsylvania. It would add 395 million cubic feet per day of capacity and cost $500 million. The project includes construction of pipeline, looping and replacement of compressor stations and is is preparing to pre-file with FERC.[3]

In January of 2019 an explosion in the pipeline injured two people and destroyed two homes in Noble County, Ohio.[4]

Expansion Background

In 2008, Spectra and ConocoPhillips announced a proposed pipeline called the TEMAX Pipeline. Gas would run through the TETCO Pipeline system, forming an agreement to deliver up to 395 million cubic feet per day of Rocky Mountain natural gas to the U.S. Northeast through the planned pipeline expansion. The expansion will start in Clarington, Ohio, running through Spectra’s Texas Eastern Transmission pipeline system to Delta, Pennsylvania.[5][6]

There have been no development updates since 2008 and the project is presumed to be cancelled.
