Tallgrass Pony Express Pipeline LLC, operated by Tallgrass, and Bridger Pipeline LLC have started an open season for the crude-carrying Pony Express Pipeline, which runs from the Williston Basin in eastern Wyoming to Cushing, Oklahoma.

The binding joint tariff open season offers incentive tariff rates for shipping commitments to move crude from Bridger’s Guernsey Hub, Tallgrass said in a statement released Feb. 14.

The season is for existing capacity on the line. The 30-day open season closes on March 15.

The Pony Express line has a capacity of 230,000 bbl/d of crude.
