Tallgrass Pony Express Pipeline Announces Binding Open Season for Crude Oil Pipeline Expansion

Tallgrass Pony Express Pipeline, LLC (“Pony Express”) announced today that it has commenced a binding open season for the previously announced expansion of its crude oil pipeline system. Pony Express is soliciting shipper commitments for crude oil transportation service from Guernsey, Wyoming and from points in northeastern Colorado and southeastern Wyoming to delivery points at Cushing, Oklahoma under a Local Tariff. The open season is scheduled to close on December 5, 2014.

Beginning in mid-2015, Pony Express expects to provide shippers who commit to the full expansion a pro rata share of interim capacity of approximately 100,000 barrels/day. The full expansion capacity is currently expected to be operational in the second half of 2016.

In addition to this Local Tariff open season, Pony Express expects to conduct one or more Joint Tariff open seasons with at least one upstream pipeline to facilitate the transportation of crude oil produced from the Powder River Basin and/or the Bakken production area into Guernsey, Wyoming.
