NuStar Energy L.P. (NYSE:NS) announced today that its affiliate, NuStar Logistics, L.P. ("NuStar"), will extend the Niobrara Falls Open Season from noon CT November 15, 2012 to noon CT December 14, 2012.

As previously announced, NuStar is assessing shipper interest in firm priority space to transport crude petroleum from the Niobrara Shale near Platteville and Watkins, Colorado to Wichita Falls, Texas (the "Niobrara Falls Project"). The Niobrara Falls Project would also have the capability to transport Permian and Granite Wash crude petroleum delivered into NuStar's Dixon, Texas Tank Farm for delivery to the various destinations. This extension will provide NuStar and its potential shippers more time to discuss strategic alternatives involving NuStar pipeline assets in these shale areas.
