Dominion Transmission Inc. (DTI) requested approval from FERC Wednesday to begin service on two expansion projects that would increase capacity on its system before the start of the winter season in the Marcellus and Utica shale region.

In separate filings Wednesday, DTI submitted requests for in-service to the Federal Energy Regulatory Commission for its Clarington project [CP14-496] and its Lebanon West II project [CP14-555].

The Clarington project, which received a certificate of public convenience and necessity from FERC last August, would add 250,000 Dth/d of capacity to DTI’s mainline system through new compression facilities, interconnects and associated equipment. DTI has proposed the project to offer additional firm transportation service to Consol Energy Inc., delivering gas from a new interconnect in Lightburn, WV, to new interconnects with Texas Eastern Transmission Co. and Rockies Express Pipeline LLC (see Daily GPI, Aug. 21, 2015).

In July, FERC granted DTI an extension to complete work on Clarington (see Shale Daily, July 26).

The Lebanon West II project received FERC approval last November. That project would add 130,000 Dth/d of firm transportation service from DTI’s MarkWest Liberty Bluestone Interconnection in Butler County, PA, to the Lebanon-Texas Gas Interconnection with Texas Gas Transmission Corp. in Warren County, OH (see Daily GPI, Nov. 23, 2015).

In its filings Wednesday, DTI asked FERC to allow it to commence service on both expansions on or before Oct. 28.
