Subject: Stage III (13%) Underrun Entitlement and Sumas M&ERP Maintenance Reminder
Notice Text:
In preparation for the Sumas Compressor maintenance, Northwest
is declaring a Stage III (13%) Underrun Entitlement for all
Receiving Parties north of Plymouth North Constraint Pt
effective Gas Day December 12, 2023 until further notice.
As a reminder and as posted in the maintenance schedule on
Northwest Pipeline's website, Northwest will be performing
critical work at the Sumas Compressor Station beginning Gas Day
December 12, 2023 through Gas Day December 17, 2023. This work
is required to complete the Modernization and Emissions
Reduction Program (M&ERP) construction activities in 2024.
During this period, scheduled volumes through the Sumas
Compressor Station will be limited to 1,012,989 Dth/d.
Northwest will coordinate with upstream operators and use
operationally available flexibility to mitigate the impact this
work will have on our customers to the greatest extent
possible.
If primary nomination requests through the Sumas Compressor
Station exceeds the available capacity of 1,012,989 Dth/d
Southbound (or whatever Northwest 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 Firm Primary
Rights of 1,297,989 Dth/d Southbound. The Deficiency Period
will continue until the work is completed on December 17, 2023.
