Project Mariner East is pipeline project to deliver propane and ethane from the liquid-rich 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 in the fourth quarter 2014. Mariner East is scheduled to be fully operational to deliver propane and ethane in Mid-2015.
Sunoco Logistics will construct a pipeline from MarkWest Energy Partners L.P.'s Houston, Pennsylvania processing and fractionation complex to an interconnection with an existing Sunoco Logistics pipeline at Delmont, Pennsylvania. The natural gas liquids will then be transported to the Marcus Hook facility where Sunoco Logistics will construct new facilities to process, store, chill, and distribute propane and ethane to local, regional and international markets.
Project Mariner East Phase II
Sunoco Logistics announced a successful Open Season for Mariner East 2 project in November 2014. For Mariner East 2, Sunoco Logistics plans to construct a pipeline from processing and fractionation complexes in Western Pennsylvania, West Virginia and Eastern Ohio for transport to the Marcus Hook Industrial Complex. Sunoco Logistics plans to construct new facilities at Marcus Hook Industrial Complex to store, chill, process and distribute propane, butane and ethane for distribution to local, domestic and international markets. Sunoco Logistics plans to offer intrastate and interstate movements to meet the demands of various markets. Mariner East 2 will expand the total takeaway capacity to 345,000 barrels per day. The Mariner East 2 pipeline is expected to be operational in Q4 2016, subject to regulatory and permit approvals.

Project Mariner West is a pipeline project to deliver ethane from the liquid-rich Marcellus Shale processing and fractionation areas in Western Pennsylvania to the Sarnia, Ontario petrochemical market. The project is anticipated to have an initial capacity to transport up to 50,000 barrels per day of ethane and can be scaled to support higher volumes as needed. Mariner West commenced operations in Q4 2013.
Project Mariner South
Mariner South Pipeline is a pipeline project to transport export grade propane and butane from Lone Star’s storage and fractionation complex in Mont Belvieu, Texas to Sunoco Logistics’ terminal in Nederland, Texas. 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 commenced operations at end of 2014. It is expected to ramp up to full capacity by 2Q15.
