FERC has given the green light to Dominion Transmission Inc.’s (DTI) Leidy South Project, which would provide 155,000 Dth/d of firm transportation service in the Mid-Atlantic region through upgrades and modifications to Dominion’s transmission pipeline system.

Dominion now has all federal authorizations for the nearly $210 million project, having complied with all applicable conditions, according to the Federal Energy Regulatory Commission.

Specifically, FERC’s project manager on Tuesday granted Dominion’s Dec. 16 request to begin the construction of compressor stations in Clinton (Finnefrock) and Franklin (Chambersburg) counties in Pennsylvania and Loudoun (Leesburg) County in Virginia. FERC considered Dominion’s implementation plan and supplemental information in giving the go-ahead.

“We have confirmed the receipt of all federal authorizations necessary to construct the requested project facilities and Dominion has complied with all applicable conditions,” said FERC’s Harry Jeudy, adding that Dominion now should file a separate request for a notice to proceed with building all of the other facilities that were included in the federal regulators’ approval of the project last year.

Last August, FERC granted a certificate for the Leidy South Project that would serve new and existing power generation facilities with natural gas traveling from the Leidy Interconnect in Clinton, PA, to points in Loudoun County, VA, moving through parts of Pennsylvania, Maryland and Virginia.

Panda Stonewall LLC, Virginia Power Services Energy Corp. Inc, and Mattawoman Energy LLC have signed binding agreements for all of the project’s capacity, Dominion told FERC.

Early last year FERC staff issued a favorable environmental assessment of DTI’s proposed project. Originally, DTI filed at FERC for the project in 2015. Gas moving on the expansion capacity would serve new and existing power generation facilities.
