The smaller of the two pipelines that make up the Westcoast Pipeline system in British Columbia (BC) was shut down last week as a precautionary measure due to heavy flooding in the province. Enbridge ceased operations on the 30 inch line in the Coquihalla river valley on Tuesday morning following two days of torrential rains that triggered major flooding and mudslides in the province. Enbridge has not said when operations will resume. A 36 inch line remained on line enabling the system to deliver up to 1.4 billion cubic feet of gas per day to customers in BC and as exports to the US Pacific Northwest the Sumas, Washington, border crossing that feeds Westcoast supply into the Northwest Pipeline system. Westcoast system capacity normally runs between 1.5 Bcf/d and 1.8 Bcf/d. The impact was immediately seen at the Sumas, which jumped $1.48 to $5.87/MMBtu for Wednesday flow.
