Jan 12 (Reuters) - The Canada Energy Regulator (CER) on Friday said it would issue a decision on a variance request from the Trans Mountain pipeline expansion project "in due course", following a one-day oral hearing in Calgary.
Trans Mountain has asked to be allowed to install smaller-diameter pipe in a 1.4-mile (2.3-km) section of the oil pipeline's route after encountering "very challenging" drilling conditions due to the hardness of the rock in a mountainous area between Hope and Chilliwack.
