Subject:  Revised - Cisco to Rangely maintenance update and deficiency warning

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.

Representative or the hotline at 713-215-6301.
