Subject: Vernal OFO and Deficiency warning for July 23
Notice Text:
Northwest is performing pigging operations from the Vernal compressor station to the Flaming Gorge area July 21-23. This was listed on Northwest’s EBB as a non-impact event, but due to increasing nominations through that corridor it is likely to be an impact for July 23. As a result, the operationally available capacity through the Vernal compressor station has been reduced from a design capacity of 353,000 Dth/d to an operationally available capacity of 280,000 Dth/d. If the scheduled quantities for gas day July 23 exceed the design capacity of 353,000 Dth/d, Northwest will issue OFO compliance notices which will bring scheduled quantities down to design capacity as outlined under Section 14.15(d) of its tariff. Affected shippers will be provided with their specific OFO obligations by 4:00 p.m. MST and shippers must comply with the OFO obligations no later than the Evening nomination deadline (5:00 p.m. MST). Further, if the scheduled quantities exceed the operational available capacity of 280,000 Dth/d for gas day July 23, Northwest will declare a Deficiency Period to allocate the primary firm nominations down from the design capacity of 353,000 Dth/d to the operationally available capacity of 280,000 Dth/d. Shipper cooperation in this matter is greatly appreciated. If you have any questions, please contact your Marketing Services Representative or the Scheduling Hotline at (801) 584-7301.
