The National Energy Board (NEB) ordered high-pressure testing of a segment of Enbridge’s Line 9 pipeline before the line, a west-to-east oil pipeline, can begin operating according to a press release issued Thursday.
“Before Line 9B becomes operational, hydrostatic testing results of three segments of the pipeline must be provided to and approved by the NEB,” the National Energy Board — Canada’s federal pipeline regulator — said.
Enbridge requested permission to reverse the flow of a 639-kilometre portion of the Line 9B pipeline between North Westover, Ontario and Montreal. Line 9B is part of the larger Line 9, which Enbridge hopes will carry diluted bitumen from the Alberta oilsands to Eastern Canada.
Community groups, particularly in Quebec, have long requested the high-pressure, hydrostatic test. A hydrotest or hydrostatic test is a commonly used method of determining if a pipeline can operate safely at its expected operating pressure. Recently a number of groups demanded the NEB explain why it would not order a hydrotest of Line 9.
