FERC staff on Wednesday issued a favorable environmental assessment (EA) of Dominion Transmission Inc.’s (DTI) proposed Leidy South project, which would provide 155,000 Dth/d of firm transportation service in the Mid-Atlantic region through upgrades and modifications to the DTI system.

Federal Energy Regulatory Commission staff said the project could be accomplished without undue harm to the environment as long as appropriate mitigation measures are taken [CP15-492].

DTI filed at FERC for the project last May (see Daily GPI, May 15, 2015).

Gas moving on the expansion capacity would serve new and existing power generation facilities. The additional capacity would run from the Leidy Interconnect in Clinton, PA, to points in Loudoun County, VA.

Customers with binding agreements for all of the capacity are Panda Stonewall LLC, Virginia Power Services Energy Corp. Inc, and Mattawoman Energy LLC.

The project would involve modifications to six existing DTI compressor stations in Pennsylvania, Maryland and Virginia, and the construction of a metering and regulating station in Virginia. The estimated cost of the project is $209.66 million.

DTI is not proposing to abandon any service; facilities that would be removed as part of the project are to be replaced, it said.

FERC will accept comments on the project through April 29.
