FERC begins enviro review process for Dominion’s Leidy South gas capacity project

The Federal Energy Regulatory Commission on May 27 issued a notice seeking comment until June 17 on a May 15 application from Dominion Transmission Inc. (DTI) for a certificate of public convenience and necessity to construct and operate the Leidy South Project.

DTI proposes to: replace two 1,100 horsepower (hp) compressor units with one 10,915 hp unit at the Finnefrock Compressor Station in Clinton County, Pa; install one suction filter/separator at the Centre Compressor Station in Centre County, Pa.; install one 13,220 hp unit at the Chambersburg Compressor Station in Franklin County, Pa.; install one 15,900 hp unit at the Myersville Compressor Station in Frederick County, Maryland; install one 8,000 hp unit at the Leesburg Compressor Station in Loudoun County, Va.; install a new cooler and filter separator at the Quantico Compressor Station in Fauquier County, Va.; and construct a new meter station at the planned Panda Stonewall Power Project in Loudoun County, Va.

The DTI project will allow DTI to provide an incremental 155 MMcf per day of firm transportation service to two power generation facilities. The total cost of the project will be approximately $209,657,857. DTI is a subsidiary of Dominion Resources (NYSE: D).

The three customers for this gas are:

  • Panda Stonewall LLC (funded by Panda Power Funds), which is developing the Panda Stonewall Power Project, a 750-MW natural gas-fired combined-cycle plant located four miles south/southeast of Leesburg, Va.
  • Virginia Power Services Energy, another Dominion Resources subsidiary, which will utilize the natural gas to help support its existing fleet of power generation facilities.
  • Mattawoman Energy LLC (funded by Panda Power Funds), which is proposing the Panda Mattawoman Power Project, an 859-MW combined-cycle station located in Brandywine, Md. The Leidy South Project will transport gas for Mattawoman Energy only to Loudoun County, Va. Further transportation of the gas to the Mattawoman plant would require subsequent transportation off of DTI’s system.

Within 90 days of this May 27 notice the commission staff will either: complete its environmental assessment (EA) and place it into the commission’s public record for this proceeding, or issue a Notice of Schedule for Environmental Review. If a Notice of Schedule for Environmental Review is issued, it will indicate, among other milestones, the anticipated date for the commission staff’s issuance of the final environmental impact statement (FEIS) or EA for this proposal. The filing of the EA in the commission’s public record for this proceeding or the issuance of a Notice of Schedule will serve to notify federal and state agencies of the timing for the completion of all necessary reviews, and the subsequent need to complete all federal authorizations within 90 days of the date of issuance of the commission staff’s FEIS or EA.
