Sunoco Logistics Partners LP is holding a binding open season for its Mariner South Pipeline, which is intended to transport export-grade propane and butane, from Lone Star NGL LLC‘s storage and fractionation complex in Mont Belvieu, TX, to Sunoco Logistics’ terminal in Nederland, TX. The pipeline is to be available for other natural gas liquids and petroleum products depending on shipper interest, Sunoco said. Initial capacity is expected to be 200,000 b/d and could be scaled to support higher volumes as needed. The pipeline is expected to be operational by the first quarter of 2015. For information, visit
