Transco pushes full service for Atlantic Sunrise gas pipe project back a week

Williams Cos. Inc.'s Transcontinental Gas Pipe Line Co. LLC moved the full in-service timeline for its 1.7-Bcf/d Atlantic Sunrise natural gas pipeline expansion back a week, now targeting the week of Sept. 17.

Transco had expected to put the almost $3 billion project, which will provide Marcellus gas takeaway capacity through southeastern Pennsylvania, in service by late August and then by Sept. 10. It gave an update in an electronic bulletin board notice posted Sept. 7, pointing to construction delays due to weather, as it has in earlier postings. The eastern U.S. had significant amounts of rain and flooding this summer.

"Transco continues to make progress in overcoming weather related delays and expects mechanical completion of its Atlantic Sunrise project ... in mid-September 2018," the company wrote. "Based on Transco's current schedule and forecasted progress, Transco is now targeting full in-service to commence as early as the week of September 17th."

Transco said it might issue a new in-service date based on when it receives the final approvals from the Federal Energy Regulatory Commission to put the expansion in service. The pipeline company asked the commission for authorization to put certain expansion facilities in service Aug. 24.

Mainline portions of the Atlantic Sunrise project providing about 550 MMcf/d of incremental gas transportation capacity are already in service.

On Sept. 4, a federal appeals court turned down requests by environmental groups and a landowner to review the Pennsylvania Department of Environmental Protection's decision to issue a Clean Water Act Section 401 certificate to Transco for the project.

The project, which consists of about 200 miles of greenfield pipeline in Pennsylvania and compressor stations, is designed to move gas from the Marcellus Shale to the Transco mainline for transportation to mid-Atlantic and Southeast markets. FERC authorized the expansion in February 2017. At the time of the approval, anchor shippers included Cabot Oil & Gas Corp., Seneca Resources Corp., Southwestern Energy Co. and WGL Midstream Inc.
