Tallgrass Pony Express Pipeline, LLC (Pony Express) and Hiland Crude, LLC (Hiland) announced today a joint open season soliciting shipper commitments for crude oil transportation service under a joint tariff from receipt points on the Hiland Double H Pipeline at Hiland's Sieler station in Montana and the North Wright and Douglas stations in Wyoming to delivery points at Cushing, Okla. The two companies expect this open season to end on Dec. 12, 2014.

Hiland will construct expansion capacity above its currently contracted and walk-up system capacity of 50,000 barrels per day, and Pony Express will construct expansion capacity above its currently contracted and walk-up system capacity of 230,000 barrels per day (which will increase by about 90,000 barrels per day upon completion of Pony Express' Northeast Colorado Lateral), in each case based on commitments received in this and other binding open seasons requiring expansion of the Pony Express and Hiland Crude systems.

Interested parties may review the details of the Open Season at either the Pony Express website at http://pipeline.tallgrassenergylp.com/Pages/OilOpenSeason.aspx?pipeline=42 or the Hiland website at http://www.hilandcrude.com.
