Notice Text:

 

As indicated in All Shippers Notice #25-162, Northwest is

currently performing DOT Hydro Tests though the Caldwell

compressor station September 23, 2025 through October 27, 2025.

 

Primary southbound nomination requests at the Caldwell CS have

exceeded the available capacity of 358,000 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 September 23, 2025. The Deficiency will be

calculated based on a design capacity of 475,000 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.
