Notice Text:

Northwest has added the following unplanned outage to the 
maintenance schedule on Northwest Pipeline’s website because of 
the results from the Snake River to Snake River tool runs. 
Northwest is performing immediate digs in the Caldwell and 
Boise corridor beginning Gas Day October 17, 2024, through Gas 
Day October 31, 2024. The available northbound and southbound 
capacities will be limited to an available capacity of 194,000 
Dth/d northbound through the Boise CS and 220,000 Dth/d 
southbound through the Meacham CS. 

As a reminder, with the new PHMSA RIN 2 rules in place, there 
will be an increase in the number of immediate conditions 
reported on Northwest’s system, which means a higher focus on 
possible reports that may require immediate attention. 
Furthermore, the criteria for what is considered an immediate 
condition has also changed resulting in an increase in 
immediate digs. Northwest Pipeline will work diligently to 
complete all work as quickly as possible to minimize any 
impacts.

Additionally, with Jackson Prairie nearly full, Northwest has 
limited balancing flexibility and requests that customers 
secure adequate supply to meet demand and avoid banking the 
system.

If primary nomination requests through the Boise CS exceed the 
available capacity of 194,000 Dth/d northbound or if primary 
nomination requests through the Meacham CS exceed the available 
capacity of 220,000 Dth/d southbound (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 499,000 Dth/d northbound 
and 500,000 Dth/d southbound, respectively. The deficiency 
period will continue until the work is completed on Gas Day 
October 31, 2024.
