Sunoco Logistics announced Thursday its plan to invest $2.5 billion in a second pipeline — Mariner East Phase 2 — that will deliver natural gas liquids from shale-rich areas to its Marcus Hook Industrial Complex on the Delaware River.
Mariner East 2 will parallel the existing, smaller Mariner East pipeline, which Sunoco said is slated to begin propane service by year's end. Mariner East 2, expected to be operational by the end of 2016, will run from Ohio through West Virginia, Pennsylvania and Delaware. It will provide an initial capacity of 275,000 barrels per day of propane, butane and ethane. The former Mariner East's capacity is 70,000 barrels per day. Together, that's 345,000 barrels per day of total NGL takeaway capacity. Each barrel contains 42 gallons.
Mariner East 2 is part of Philadelphia-based Sunoco's plan to "provide critical pipeline transportation" from the Marcellus and Utica shales. It also enables development at Marcus Hook, "as we convert a former refinery site into a world-class natural gas liquids hub in southeastern Pennsylvania," said Michael J. Hennigan, Sunoco president and CEO.
