Subject: Update - Cisco to Rangely Anomaly Investigations
Northwest Pipeline is pleased to announce that the third pressure restriction
that was scheduled through Gas Day June 30, 2021 in the Cisco to Rangely
corridor has been completed. Effective in the Evening cycle for Gas Day July
1 through Gas Day July 31, the capacity through the Cisco compressor is
175,000 Dth/d northbound and 236,000 Dth/d southbound.
If the primary scheduled quantities exceed the operationally available
capacity of 175,000 Dth/d northbound and 236,000 southbound, or a volume that
Northwest is unable to mitigate, Northwest will declare a Deficiency Period
based on the Cisco compressor design capacity of 286,000 Dth/d northbound or
359,000 Dth/d southbound.
Northwest will continue to communicate through notices and update the
maintenance calendar as we navigate the 92 anomaly digs this summer which are
scheduled to complete on October 30, 2021.
If you have any questions, please call your Commercial Services
Representative or the hotline at 713-215-6301.
