Sunoco Logistics Partners L.P. Announces Successful Open Season for Project Mariner East

Sunoco Logistics Partners L.P.

announced today a successful open season for Mariner East, a pipeline project to deliver propane and ethane from the liquid-rich Marcellus Shale areas in Western Pennsylvania to Sunoco, Inc.'s facility in Marcus Hook, Pennsylvania, where it will be processed, stored, and distributed to various domestic and waterborne markets. Binding commitments for all of the pipeline capacity offered have been received from shippers enabling the project to move forward. Mariner East, along with the previously announced Mariner West project which will deliver ethane to the Sarnia, Ontario market by mid-2013, will provide Marcellus Shale basin producers with a comprehensive natural gas liquids takeaway solution. Sunoco Logistics is projecting to invest over $600 million for the Mariner projects.
