Subject:  Chehalis Compressor Station Deficiency Period

Notice Text:

As indicated in All Shippers Notice #25-048, Northwest is 
currently experiencing unplanned maintenance at the Chehalis 
compressor station. 

Primary southbound nomination requests at the Chehalis 
compressor have exceeded the available capacity of 600,000 
Dth/d southbound (or whatever Northwest cannot mitigate). 
Therefore, pursuant to Sections 10.2 and 10.3 of Rate Schedule 
TF-1 in Northwest's Tariff, Northwest hereby gives notice of a 
Deficiency Period for Gas Day April 9, 2025. The Deficiency 
will be calculated based on a design capacity of 672,000 Dth/d 
southbound. The Deficiency Period will continue until the work 
is completed. Northwest will post on its EBB if unable to 
mitigate volumes each day until the work is completed.

Please reference the Maintenance Schedule tab at 
www.northwest.williams.com for more information.
