• Sunoco and parent company Texas-based Energy Transfer Partners are building Mariner East 2, which will run 350 miles the entire width of Pennsylvania. The pipeline is part of a $5.1 billion effort by Sunoco Logistics to transport natural gas liquids such as propane and ethane to a refinery at Marcus Hook where it will be stored and transported, mostly to overseas buyers.

    The Mariner East 2 20 inch pipeline began service on December 29, 2018.  Sunoco parent company Energy Transfer LP announced that the 16 inch Mariner East 2X pipeline is expected to be completed late this year.

    Energy Transfer issued a statement on 2/8/19 that they are commited to bringing the Pennsylvania project into full compliance with all environmental permits and applicable regulations.
