EQT Midstream Partners LP (EQM) has entered into an agreement with Range Resources Corp. to construct a more than 500 MMcf/d natural gas header pipeline for the producer’s Marcellus and Utica shale operations in Southwestern Pennsylvania. Backed by a long-term firm capacity reservation commitment, EQM said it would invest $250 million in the system. It would include 32 miles of pipeline and 32,000 hp of compression. EQM said the companies plan to complete the project in two phases, with the first entering service in 3Q2016 and the second in 2017.
