Effective Gas Day October 3, 2019 and until further notice,

Northwest is issuing an OFO Recall Advisory and Operational Flow Order

(OFO) through the Roosevelt compressor and the Plymouth South

constraint location 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 northbound scheduled quantities exceed the greater of

Northwest’s design capacity of 546,000 Dth/d at Roosevelt or 536,300

Dth/d at Plymouth South, or the operationally available at those

locations 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).

Additionally, Northwest would like to remind customers that with the

Jackson Prairie and Clay Basin facilities shut-in on various days

during October, Northwest has very limited flexibility to handle

banking or drafting. If excess banking or drafting occurs an underrun

or overrun Entitlement may be issued.

Shippers can monitor throughput quantities and obtain a copy of

Northwest’s OFO procedures on Northwest’s website at

www.northwest.williams.com.

If you have any questions, please contact your Marketing Services

Representative or the Scheduling Hotline at (801) 584-7301.
