Energy Transfer Partners, L.P. (NYSE: ETP) and Regency Energy Partners LP (NYSE:RGP) today announced that their joint venture, Lone Star NGL LLC (“Lone Star”), has Board of Directors approval to construct a 533 mile, 24 and 30-inch natural gas liquids (NGL) pipeline from the Permian Basin to Mont Belvieu, Texas, and convert Lone Star’s existing West Texas 12-inch NGL pipeline into crude oil/condensate service. The new pipeline and conversion projects, estimated to cost between $1.5 and $1.8 billion, are expected to be operational by third quarter of 2016 and first quarter of 2017, respectively.

The new pipeline is being built to accommodate Lone Star’s contracted NGL transportation volumes that will exceed Lone Star’s existing 290,000 barrels per day of capacity from the Permian Basin by 2016. The 24-inch pipeline will initially be sized to transport 375,000 barrels per day from the Permian Basin to Bosque County while the 30-inch pipeline is currently sized to transport 495,000 barrels per day from Bosque County to Mont Belvieu, Texas. The pipelines can be easily expanded to transport additional volumes in the future.

Lone Star’s 12-inch West Texas NGL pipeline will be converted to crude/condensate service. The pipeline runs from the Midland area to the Gulf Coast and will be sized to ship 70,000 barrels per day to Corsicana, Texas and 100,000 barrels per day to Sour Lake, Texas. Lone Star plans on holding an open season for the crude/condensate service at a future date.

Potential shippers interested in transportation service may contact Lone Star via e-mail at M.Mckee@energytransfer.com to request additional information.
