Business Wire

PHILADELPHIA -- May 06, 2013

Sunoco Logistics Partners L.P. (NYSE: SXL), today announced that it has
received enough binding commitments to enable its Mariner South Pipeline to
proceed as planned. The Mariner South Pipeline will transport export grade
propane and butane from Lone Star NGL LLC’s storage and fractionation complex
in Mont Belvieu, Texas to Sunoco Logistics’ terminal in Nederland, Texas.
Although sufficient commitments have been received for this project to move
forward, the binding open season period will remain open to solicit additional
shipper interest.

As previously announced, in addition to export grade propane and butane, the
pipeline will be available for other natural gas liquids and petroleum
products depending on shipper interest. The pipeline is anticipated to have an
initial capacity to transport approximately 200,000 barrels per day and can be
scaled to support higher volumes as needed. The pipeline is expected to be
operational in the first quarter of 2015.
