EQT Corporation subsidiary Equitrans has received approval from the Federal Energy Regulatory Commission for the construction of a new natural gas pipeline system in Pennsylvania and West, US, as part of its ongoing Marcellus capacity expansion.

Equitrans will build 41.5 miles of a 24in-diameter pipeline and 2.7 miles of a 16in-diameter pipeline running from Wetzel County in West Virginia to Greene County in Pennsylvania, along with a new compressor station in Greene County.

The pipelines will be interconnected with MarkWest’s Mobley processing complex to provide producers with an option to transport liquids-rich natural gas to pipelines serving the Mid-Atlantic and north-eastern markets.

The project will expand Equitrans’ mainline transmission system to address the rapid development of natural gas from the liquids-rich and dry areas of the Marcellus Shale formation in the Central Appalachian Basin.
