Expansion of the Trans Mountain oil pipeline would be delayed by months and incur hundreds of millions of dollars of additional cost, unless a regulator approves a change in its route, the Canadian government corporation that owns the pipeline told a regulator in a filing on Thursday.
Trans Mountain is asking the Canada Energy Regulator to approve a change from its approved route on a 1.3-kilometre (0.8 mile) section just south of Kamloops, British Columbia, saying the micro-tunneling construction method necessary on the existing route is not feasible technically or economically.
