An affiliate of Plains All American Pipeline (NYSE: PAA) today announced a binding open season for long-term commitments for light crude oil transportation service on its Western Corridor Pipeline System (the “System”).

By submitting a binding proposal, bidders are offering to enter into a long-term throughput and deficiency agreement for pipeline capacity. Prior to participating in the open season, interested parties must execute a confidentiality agreement to govern the receipt of the open season documentation.
