During this maintenance, Jackson Prairie's operational capacity for injections and withdrawals will be set to zero. Due to the forecasted warmer than normal weather and the upcoming holiday, at this point, Northwest is not foreseeing the need to declare an Entitlement Period while Jackson Prairie is shut-in. However, if the actions of Shippers or individual Shippers result in excessive banking or drafting, Northwest may declare an Entitlement for specific geographical locations on its system. Please contact your Marketing Services Representative or the Northwest Pipeline Hotline at (801) 584-7301 if you have any questions. JR/MR/MS
