Sunoco Logistics Partners L.P. said it was seeking commitments from shippers for a separate and mostly new pipeline that would generally follow the path of its current cross-state Mariner East pipeline, which carries natural-gas liquid fuels from the Marcellus Shale region to Marcus Hook. The binding open season will test whether there is a market for the project, which would be called Mariner East 2 and transport ethane and propane. The materials, primarily used in petrochemical production, are being exported from the former refinery site in Marcus Hook. Industry experts project production of natural gas liquids from the Marcellus Shale and the neighboring Utica Shale to double by 2016, the targeted completion date of the pipeline project. - Andrew Maykuth
