National Energy Board to hold public hearing to consider Enbridge’s Line 21 Segment Replacement Project

News Release

May 19, 2017 – Calgary, Alberta – National Energy Board

The National Energy Board (NEB) announced today that it will hold a public hearing to review an application from Enbridge to replace a section of its Line 21 pipeline in the Northwest Territories. The hearing will begin the week of August 8 at the Fort Simpson Recreation Centre.

The hearing will include a written process with an oral portion including cross-examination and argument. The NEB will also hear oral traditional evidence from Indigenous participants. The hearing will be broadcast in English and Dene Zhatie.

To help participants understand how the NEB will review this application, NEB staff will hold an information session on June 6 at the Thomas Simpson School Library from 6:30 – 8 pm.

The NEB has accepted all requests for participation. Five groups have been granted Intervenor status and six groups have been granted Commenter status.

On March 10, Enbridge applied to the NEB to replace a 2.5-kilometre-long section of its Line 21 pipeline, also known as the Norman Wells Pipeline. The new pipe would be installed under the Mackenzie River using a trenchless crossing method called horizontal directional drilling. Enbridge is also requesting permission to leave the section of pipeline that is being replaced under the Mackenzie River (decommission).

The National Energy Board is an independent federal regulator of several parts of Canada’s energy industry. It regulates pipelines, energy development and trade in the public interest with safety as its primary concern. For more information on the NEB and its mandate, please visit
