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.
