Subject: Chehalis Notice of Recall and OFO and Potential Deficiency

Notice Text:

Effective Gas Day Thursday, September 24, 2026, and until 
further notice, Northwest is issuing an OFO Recall Advisory and 
Operational Flow Order (OFO) through the Chehalis compressor 
pursuant to Section 14.15(d) of its Tariff. 

Under the OFO Recall Advisory, Shippers are required to: (1) 
recall capacity that is subject to an OFO recall provision; or 
(2) take other action that is acceptable to Northwest, to 
satisfy its OFO obligation.

If the southbound scheduled quantities exceed the greater of 
Northwest’s design capacity of 672,000 Dth/d at Chehalis or the 
operationally available capacity at that location on that day, 
Northwest will provide Shippers with their specific OFO 
obligations by 4:00 p.m. MST. Shippers must comply with their 
OFO obligations no later than the Evening nomination deadline 
(5:00 p.m. MST).

If an OFO is necessary for a given Gas Day, Northwest will wait 
until the Evening scheduling process to provide notice of a 
Declared Deficiency period and will make deficiency cuts to 
bring the nomination requests at the Chehalis compressor from 
the southbound design capacity of 672,000 Dth/d to the 
operationally available capacity of 492,000 Dth/d. If an OFO is 
not necessary, but a deficiency period is, Northwest will 
provide notice of a Declared Deficiency period and will make 
deficiency cuts in the Timely scheduling process to bring the 
nomination requests at the Chehalis compressor to the 
operationally available capacity of 492,000 Dth/d (or whatever 
NWP cannot mitigate during any day of the maintenance period), 
all pursuant to Sections 10.2 and 10.3 of Rate Schedule TF-1 in 
Northwest's Tariff. The deficiency period will continue until 
the work is completed.

Shippers can monitor throughput quantities and obtain a copy of 
Northwest’s OFO procedures on Northwest’s website at 
www.northwest.williams.com.
