Project Information

On November 5, 2014, Enbridge Pipelines Inc. submitted an application [Folder 2546069] for the Line 3 Replacement Program. The proposed project would include:

  • replacing the existing Line 3 pipeline, 863.6 mm (outside diameter) crude oil pipeline with a new, 914.4 mm (Outside diameter) crude oil pipeline;
  • installing 55 new remotely operated sectionalizing valves;
  • installing 18 new pump stations and associated infrastructure and equipment;
  • building 3 new storage tanks at the Hardisty Terminal;
  • associated interconnection work at facilities; and
  • decommissioning the existing Line 3 pipeline.

Once complete, the pipeline will have the ability to carry approximately 760,000 barrels per day.

The majority of the Line 3 replacement pipeline would be situated adjacent to Enbridge’s Mainline System corridor. The Project footprint for the Line 3 Replacement Pipeline will typically be 45 metres in width, including 12 metres of permanent easement, with an additional 33 metres of temporary workspace.

On November 29, 2016, Governor in Council directed the National Energy Board (NEB) to issue a Certificate of Public Convenience and Necessity [Filing A80884] for the Line 3 Replacement Project. This Certificate and the Orders authorizing the construction and operation of the Project are subject to 89 conditions that will be enforced by the NEB.

The targeted in-service date is early 2019. Decommissioning activities are proposed to begin once the Line 3 Replacement Pipeline is in service, and would take 12 to 18 months to complete.
