Item 8.01 Other Events.

On November 17, 2015, NGL Energy Partners LP (“NGL”) entered into an agreement with Saddlehorn Pipeline Company, LLC (“Saddlehorn”), under which NGL will acquire an undivided interest in a crude oil pipeline currently under construction (the “Pipeline”). The Pipeline will have several points of origin in Colorado and will terminate in Cushing, Oklahoma. NGL will have the right to utilize 150,000 barrels per day of capacity on the Pipeline. Magellan Midstream Partners, LP is serving as construction manager and operator of the Pipeline. After the Pipeline is placed into service, operating costs will be allocated to NGL based on its proportionate ownership interest and throughput.

In October 2014, NGL completed a successful open season in which it received the requisite support, in the form of ship-or-pay volume commitments from multiple shippers, to begin construction of Grand Mesa Pipeline, which was planned to originate in Colorado and terminate in Cushing, Oklahoma. Through its undivided interest in the Pipeline, NGL will have sufficient capacity to service these customer contracts at the same origin and termination points. NGL will retain ownership of its previously acquired easements for the potential future development of transportation projects involving petroleum commodities other than crude oil and condensate. With the consent and participation of Saddlehorn, NGL and Saddlehorn may consider future opportunities using these easements for projects involving the transportation of crude oil and condensate.

A press release announcing the agreement with Saddlehorn is attached as Exhibit 99.1 to this Current Report on Form 8-K.
