The proposed pipeline will expand deliverability to the Cove Point LNG Terminal on the Transco system. The project will connect natural gas produced by Cabot Oil & Gas and Seneca Resources Company in the Marcellus and Utica regions of Pennsylvania with demand markets along the Atlantic Seaboard by the 2021-2022 winter heating season. Local distribution company UGI Utilities will be rely on deliveries from Leidy South to directly serve its customers in northeast Pennsylvania. The project includes 6.3 miles of existing pipe replacement, 5.9 miles of new pipeline loop segments along the existing Transco pipeline corridor, and horsepower additions at two existing compressor facilities. The project also will include two new greenfield compressor facilities in Pennsylvania.
In July 2020, the Federal Energy Regulatory Commission (FERC) approved the project. In November 2020 it was reported that construction was ahead of schedule and that the pipeline would be partially placed in service within a month.
According to the U.S. Energy Information Administration, as of April 2021 the project was partially complete.
