Notice Text:
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.
