FERC Friday issued a favorable environmental assessment (EA) to Dominion Transmission Inc.'s proposal to expand its storage system in Maryland, Ohio, West Virginia and Pennsylvania.

"Approval of the proposed project, with appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment," staff of the Federal Energy Regulatory Commission said in the EA on the Allegheny Storage Project [CP12-72].

The project would provide storage services of up to 125,000 Dth/d and transportation service of 115,000 Dth/d in the four states. Dominion Transmission, a subsidiary of Richmond, VA-based Dominion, has called on FERC to issue a certificate by December so it can begin construction by April 2013 and place the facilities in service by November 2014. A Dominion spokesperson told NGI Friday that the proposed timeline is still intact.

The $115 million project calls for the construction of a 16,000 hp Myersville Compressor Station and a 30-inch diameter suction and discharge pipeline in Frederick County, MD; a new 3,550 hp Mullett Compressor Station and associated pipeline facilities in Monroe County, OH; and the installation of replacement pipeline facilities and ancillary equipment at the existing Sabinsville Storage Station in Tioga County, PA.

The additional gas storage and transportation capacity associated with the project has been fully subscribed by Washington Gas Light, Baltimore Gas & Electric and Peoples TWP LLC, according to Dominion.
