BC Pipeline Operational Upset - Transmission South Update - November 30, 2018


Enbridge continues to advance the return-to-service plan of its T-South natural gas transmission system following the rupture that occurred near Prince George, British Columbia, on October 9, 2018.


Enbridge filed the engineering assessment to operate the 36” pipeline on the segment from Station 9 to Huntingdon, commonly referred to as 9L2, at maximum operating pressure on November 19, 2018 (referred to in Notice #51100 posted on November 17, 2018).  Today the NEB issued an amending order to increase the operating pressure on the 9L2 segment to its maximum operating pressure. Enbridge expects an increase in capacity at Huntingdon to approximately 1.4 Bcf/d. The capacity on the system will be gradually increased over the next few days and there may be daily capacity fluctuations while Enbridge does the work required to increase capacity and stabilize the system.


The daily available capacity for December 1, 2018 – December 3, 2018 will be posted on the Customer Interface shortly.


Work will continue to complete engineering assessments on the remaining 36” pipe segments. Once approval from the NEB is granted, these pipe segments will be brought back safely to normal operating pressure. More information on expected timing and capacity gains from these segments returning to normal operating pressure will be provided in future notices.
