SemGroup and NGL Energy Partners LP Announce Glass Mountain Pipeline STACK Extension

TULSA, Okla., Dec. 19, 2016 -- SemGroup^® Corporation (NYSE:SEMG) and NGL Energy Partners LP (NYSE:NGL) today announced that its jointly owned venture, Glass Mountain Pipeline, LLC will construct a 44-mile pipeline extension of the Glass Mountain Pipeline system in Oklahoma. This extension will deliver crude oil from north-central Oklahoma’s STACK resource play to Cushing, Okla.

“We’re excited about this opportunity to enter the STACK,” said David Minielly, vice president of SemGroup’s crude operations. “It’s a continuously growing area with strong economics for producers. We believe in the play and are happy to offer a new midstream option to meet producer demands.”

“The STACK extension will provide local producers with a cost-effective and reliable transportation solution from the core of the STACK to Glass Mountain’s storage facilities in Cushing, which enable further delivery to refineries and the Gulf Coast,” said Don Robinson, executive vice president of NGL’s crude operations. “The extension will tie-in to the existing Glass Mountain mainline facilitating a shortened construction timeline.”

Glass Mountain Pipeline has also entered into a long-term, fee-based transportation agreement with a large investment grade producer in the STACK that includes a committed area of dedication. Route selection is complete and right-of-way acquisition is underway. The extension is expected to be in service during the fourth quarter of 2017, pending the timely acquisition of right-of-way and the satisfaction of all necessary regulatory requirements.

Glass Mountain Pipeline is a joint venture owned equally between SemGroup Corporation and NGL Energy Partners LP. The current pipeline is 215-miles long and delivers crude oil from the Mississippi Lime and Granite Wash plays to Cushing.
