A few weeks ago MDN observed that Sunoco Logistics’ is planning a second Mariner East NGL pipeline to run alongside the pipeline they’re working to complete now that runs from western PA all the way to the Marcus Hook refinery near Philadelphia (see Sunoco Logistics Planning Second Mariner East Pipeline for NGLs). We wouldn’t say Sunoco’s plans for a second pipeline have been shrouded in secrecy or conspiratorial, but we would say they haven’t exactly been forthcoming about their plans either–until now.
Yesterday Sunoco announced a binding open season to allow producers to sign up for capacity on the Mariner East 2 pipeline (official name). The open season began yesterday but we find no mention of when it will end, so perhaps it’s open-ended for now. (Usually open seasons last for a month or so.) The plan is to have this new pipeline operational in early 2016. Here’s the press release from Sunoco Logistics announcing the open season for Mariner East 2 (with map):
