Notice Text:
As indicated in All Shippers Notice #26-162, Northwest is
currently performing maintenance at the Sumas CS through

Primary southbound nomination requests at the Sumas CS have

for Gas Day September 02, 2026. The Deficiency will be
calculated based on a design capacity of 1,409,000 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.
