Common Streams

As set out in the Pony Express Rules and Regulations, and as previously discussed with all Committed Shippers, Pony Express will be a “multiple common stream” carrier. Pony Express will transport batches of up to three common streams from its Guernsey origin, and a fourth common stream from northeastern Colorado. As of April 7, 2015, the common streams will be characterized as follows:

1. The Bakken Light Sweet common stream or “BLS” will originate at Guernsey and will contain not greater than .2% sulfur and will have an API gravity of not less than 40 degrees or more than 46 degrees.


2. The Mixed Sweet common stream or "MXS" will originate at Guernsey and will contain not greater than .5% sulfur and will have an API gravity of not less than 30 degrees or more than 38 degrees.


3. The Guernsey Wyoming Intermediate common stream or “GWI” will originate at Guernsey and will contain not greater than .42% sulfur and will have an API gravity of not less than 36 degrees or more than 42 degrees.


4. The Niobrara common stream or “NIO” will originate at receipt points on the NECL and will contain not greater than .42% sulfur and will have an API gravity of not less than 34 degrees or more than 42 degrees.
