FERC has prepared a draft environmental impact statement (DEIS) for a Tellurian Inc. pipeline project that would potentially serve natural gas demand in Southwestern Louisiana and the company’s Driftwood liquefied natural gas (LNG) export project. 

The Federal Energy Regulatory Commission (FERC) concluded that construction and operation of the Driftwood Line 200 and Line 300 projects would result in some environmental impacts that could be mitigated. The Commission found that most impacts would be temporary and occur during construction. 

“With the exception of climate change impacts, that are not characterized in this EIS as significant or insignificant, we conclude that project effects would not be significant based on implementation of Driftwood’s impact avoidance, minimization and mitigation measures, as well as their adherence to our recommendations,” FERC said. 

Commission staff developed specific mitigation measures for construction and operation, recommending that they be included as conditions for authorizing the pipelines. The comment period for the DEIS closes July 5. 

The company wants to build a 37-mile, 42-inch diameter system. Line 200 would be the first phase of the project, which could come online next year pending regulatory approvals. Line 300 would follow.

The pipelines would have the ability to move 5.7 Bcf/d from the Haynesville Shale to industrial, petrochemical, manufacturing and LNG plants located near Lake Charles, LA. Volumes in the region are growing. Infrastructure capacity there is projected to be limited in the years ahead as production grows, along with more industrial and natural gas export activity.

Tellurian is developing the 27 million metric tons/year Driftwood LNG export terminal in the region, but has yet to sanction the project.

The system would originate in Beauregard Parish and end in Calcasieu Parish. It would pair shippers with more Haynesville gas via new infrastructure near the Texas Eastern Transmission Co. and Transcontinental Gas Pipe Line Co. system. Subsidiary Driftwood Pipeline LLC launched a binding open season last year. According to regulatory filings, Tellurian said it signed a 20-year transportation agreement for 4.6 Bcf/d with an undisclosed foundation shipper.
