Notice Text:
* Revised as a Critical Notice
As posted in the maintenance schedule on Northwest's website and as
communicated in the annual maintenance call, Northwest will be performing
anomaly investigations through October 30, 2021 in the Cisco to Rangely
corridor.
The next phases of the maintenance involving digs and pressure restrictions
has been updated, along with the allowable scheduled quantities through the
Cisco compressor station:
June 3 through June 8: 66,000 Dth/d north and 210,000 Dth/d south
June 9 through June 22: 75,000 Dth/d north and 210,000 Dth/d south
If primary scheduled quantities exceed the northbound operationally available
capacity of 66,000 Dth/d or 75,000 Dth/d, respectively, or 210,000 Dth/d
southbound, or a volume that Northwest is unable to mitigate, Northwest will
declare a Deficiency Period based on the Cisco compressor design capacity of
286,000 Dth/d north or 359,000 Dth/d south.
Northwest will continue to communicate through notices and updated
maintenance calendar as we navigate the 92 anomaly digs this summer which are
scheduled to complete on October 30, 2021.
