Subject:  Soda to Pegram Digs - Maintenance Schedule Update/Reminder

Notice Text:

As posted in the maintenance schedule on Northwest Pipeline's 
website, Northwest is performing anomaly digs from Soda to 
Pegram from September 8, 2023 through October 13, 2023. The cut 
point will be the Kemmerer Compressor Station which will be 
limited to 409,000 Dth/d northbound.

Please note the correction in design capacity, which is 655,000 
Dth/d and the change in available capacity, which is 409,000 
Dth/d. These capacities were previously listed/communicated 
incorrectly as 415,000 Dth/d for design and available capacity 
as referenced in All Shipper Notice #23-183.

Once the first two digs have been completed, which should take 
about one week, the available capacity will be increased to 
423,000 Dth/d for the remainder of the work. Northwest will 
send out another notice once available capacity can be 
increased to 423,000 Dth/d.

If primary nomination requests through the Kemmerer Compressor 
Station exceeds the available capacity of 409,000 Dth/d 
northbound (or whatever NWP can 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 on, or about, October 13, 2023. 

Please reference the Maintenance Schedule tab at for more information.

If you have any questions, please call your Commercial Services 
Representative or the hotline at 713-215-6301.
