The Mariner East pipeline projects (plural) are an important part of the shale energy story in Pennsylvania, Ohio and West Virginia. As is the Marcus Hook Industrial Complex (what we call the Marcus Hook refinery). Currently between Mariner East 1 and 2, somewhere around 170,000 barrels of NGLs (mostly ethane and propane) flow to Marcus Hook and most of that gets exported to other countries. Mariner East 2X is currently under construction and due to come online next year, increasing that number significantly. For many Marcellus/Utica drillers, selling NGLs is the difference between being profitable and not profitable.
