Prior Notice:
Subject: Rocky Mountain Pool Looping Related to Vernal Outage
Notice Text:
As indicated in All Shippers Notice #26-204, Northwest is
currently performing maintenance at the Vernal Compressor
Station that restricts available capacity to net 0 Dth/d
northbound or net 0 Dth/d southbound through Gas Day October
19, 2026. Northwest is aware of pool looping impacts occurring
within the Rocky Mountain Pool during the outage period. These
impacts are being reflected in the Intraday sub-cycle 3
scheduling cycles and are the result of constraints and
interactions within Northwest’s scheduling model.
At this time, there is no manual override or system
modification that can be implemented prior to the completion of
the outage. Therefore, for the remainder of the outage period,
Northwest recommends that Shippers avoid the Rocky Mountain
Pool where feasible and instead utilize point-to-point
transportation.
To assist Shippers affected by these impacts, Northwest will
accommodate Post ID requests necessary to align transactions
impacted by pooling activity during the outage period.
For Gas Days October 8 through October 14, 2026, Post ID
requests and all required party approvals must be received no
later than October 20, 2026.
For Gas Day October 15, 2026, and each subsequent Gas Day
through the conclusion of the outage, Post ID requests and all
required party approvals must be received within three (3)
business days after the applicable Gas Day.
If Northwest does not receive all required approvals within the
applicable timeframe, the Post ID request will not be processed
and Northwest will create the applicable Shipper imbalance(s).
If you have any questions, please call your Commercial Services
Representative or the hotline at 713-215-6301.
