Saint-Sébastien Extension Project

TransCanada is proposing to construct, own and operate the Saint-Sébastien Extension Project (the Project), a new natural gas transmission pipeline in the municipalities of Saint-Sébastien and Pike River. This pipeline is needed to increase capacity on the system in order to continue to provide homes, businesses, schools and hospitals with a safe and reliable source of natural gas.

The Project will include the construction of approximately 4 kilometres (km) of 12-inch diameter pipe for the purpose of transporting natural gas. It will parallel a part of the existing Canadian Mainline in Quebec, and will start at the Saint-Sébastien Meter Station at route 133 and end at a new proposed valve and pig-receiver site in the municipality of Pike River, near the Chemin Molleur. Pig launchers and receivers are facilities that enable an electronic inspection tool called a “smart pig” to travel inside a functioning pipeline in order to inspect the condition of the pipe. This Project includes a new pig launching facility to be located at an existing valve site near the Rang des Dussaults.

Subject to regulatory approval, construction is scheduled to begin in the second quarter of 2017, and the pipeline will be placed in to service by the fourth quarter of 2017.

TransCanada will be engaging with landowners, municipal officials, First Nation and Métis communities and organizations, and other stakeholders as part of the engagement process. Feedback from consultation, in addition to environmental and engineering studies will be taken into consideration as part of the application to the National Energy Board (NEB).

On May 19, 2016, TransCanada filed a section 58 application with the NEB for its proposed Saint-Sébastien Extension Project. To view a copy of the Projects application, please click on the links below:
