Rockies Express (REX) said Wednesday it was issuing an Advisory Action Notice "to attempt to alleviate and forestall the development of a situation where the operational integrity of its system upstream of the Cheyenne Compressor Station is jeopardized."

REX said it is advising shippers that hourly volumes at these receipt points should flow at one-24th of the daily nomination.
