Valves on two Enbridge pipelines in Southern Ontario were closed by unknown persons early yesterday morning, making this the fourth time in two months that pipeline flows were interrupted.
According to an article on the website of Briarpatch Magazine, Line 9 was shutdown for several hours and a valve on Line 7 was closed part way. The article quotes an Enbridge spokesperson “There are no impacts to client deliveries in either case.”
Line 9 is a forty year old oil pipeline that runs between Sarnia Ontario and Montreal. Enbridge recently received approval from the National Energy Board to increase the capacity of the pipeline by 20% and to pump diluted bitumen from the tar sands through it from west to east.
