Sunoco Logistics Partners L.P. (NYSE: SXL) announced on Thursday the commencement of a binding Open Season for its Mariner East 2 Expansion Project. This Open Season is for expanded capacity on the Mariner East 2 system which will be able to transport additional volumes of petroleum products, including natural gas liquids and condensate from processing facilities built in the liquid-rich Marcellus and Utica Shale areas in Western Pennsylvania, West Virginia and Eastern Ohio to Sunoco Logistics’ Marcus Hook Industrial Complex on the Delaware River.

Project Mariner East is a pipeline project to deliver propane and ethane from the Marcellus Shale areas in Western Pennsylvania to the Marcus Hook facility, where it will be processed, stored, and distributed to various domestic and waterborne markets. The project is anticipated to have an initial capacity to transport approximately 70,000 barrels per day of natural gas liquids and can be scaled to support higher volumes as needed. Mariner East commenced initial operations of Propane in the fourth quarter 2014 and is scheduled to be fully operational to deliver propane and ethane in Mid-2015.

Sunoco will construct a pipeline from MarkWest Energy Partners L.P.’s Houston, Pennsylvania processing and fractionation complex to an interconnection with the comapny’s existing pipeline at Delmont, Pennsylvania. The natural gas liquids will then be transported to the Marcus Hook facility.

Shippers have long expressed interest in an expansion of Project Mariner East 2 to increase the capacity available for transportation of propane and butane from the NGLs Origin Points to the SPMT Terminal, increase the capacity available for transportation of ethane from Houston, PA to the SPMT Terminal, and provide capacity for transportation of C3+, natural gasoline and condensate from some or all of the NGLs Origin Points to the SPMT Terminal.

The Open Season offers service for ethane, propane, butane, C3+, natural gasoline and condensate depending upon customer interest. Refined product movements will be considered if there is sufficient customer interest. The Mariner East 2 Expansion Project is expected to commence operations as early as 2017.

Subject to the terms of the Open Season, priority service will be available to shippers making long-term volume commitments during the Open Season. The Notice of Open Season is available on the Sunoco Logistics website.
