Tallgrass’ Pony Express Pipeline Secures Committed Shipper for Platteville Extension in Northeast Colorado and Announces Binding Open Season

Tallgrass Energy Partners, LP (NYSE:TEP), through its subsidiary Tallgrass Pony Express Pipeline, LLC (Pony Express), today announced a binding open season soliciting additional shipper commitments for light crude petroleum transportation service on a potential extension of the Pony Express System. Pony Express has already secured a commitment on the proposed Platteville Extension, which would provide transportation service from a receipt point near Platteville in Weld County, Colo. The Platteville Extension would include a receipt point located at Saddle Butte Pipeline’s Milton Terminal near Platteville, Colo., among other potential receipt points.

Shippers will have access to delivery points at 1) Buckingham, Colo.; 2) El Dorado, Kan.; 3) Ponca City, Okla.; and 4) Pony’s six final terminal destinations in Cushing, Okla., under a Local Tariff that may accommodate additional delivery points in the future. The light crude petroleum, also known as condensate, will be batched in the pipeline. Participating shippers will agree to ship petroleum having an API gravity of not less than 47 degrees or more than 57 degrees and a sulfur content not to exceed 0.2 percent.

Based upon shipper commitments received in this binding open season, Pony Express will add new capacity to provide the transportation service from Colorado to Oklahoma. Pony Express expects the open season to end on July 17, 2017.

Interested parties may review the details of the open season after executing a confidentiality agreement obtained by contacting Tallgrass representatives Kyle Quackenbush, 303.763.3319; or Dean Dick, 307.232.4430.
