Notice Text:

As posted in the maintenance schedule on Northwest Pipeline's 
Website and as referenced in Notice ID 23-247 & 23-225, 
Northwest is currently performing ERP HP replacement at the 
Pegram Compressor Station scheduled to be completed on November 
11, 2023. Due to construction challenges, the work outage will 
now be extended by one week and is now scheduled to be 
completed on November 18, 2023.

The available capacity at the Kemmerer compressor station will 
continue to be limited through the duration of the work. 
However, the available capacity will be increased from 585,000 
Dth/day Northbound to 602,000 Dth/day Northbound starting Gas 
Day November 12, 2023 through November 18, 2023. 

If primary nomination requests through the Kemmerer Compressor 
Station exceeds the available capacity of 602,000 Dth/day 
Northbound (or whatever NWP cannot mitigate during any day of 
the maintenance), pursuant to Sections 10.2 and 10.3 of Rate 
Schedule TF-1 in Northwest's Tariff, Northwest will give notice 
of a Declared Deficiency Period based on a design capacity of 
655,000 Dth/d Northbound. The deficiency period will continue 
until the work is completed. 

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

Representative or the hotline at 713-215-6301.
