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.
