Sunoco Logistics Partners announced yesterday the “open season” (the period of time when companies commit to pipeline capacity) for the Mariner East pipeline to deliver natural gas liquids to the Marcus Hook refinery near Philadelphia was a complete success with all existing planned pipeline capacity now spoken for. Mariner East will connect to the currently closed Marcus Hook refinery near Philly which will soon be reopened with a major new investment to convert the plant to refine propane and ethane from the Marcellus Shale in western PA. The processed propane and ethane from Marcus Hook will be sold domestically and exported internationally.
The open season was so successful, Sunoco is considering a second open season (building more pipeline capacity). In a related announcement, Range Resources said they are the anchor shipper for the pipeline (see this MDN story), as well as MarkWest Energy Partners (see this MDN story).
