National Energy Board Hearing for Line 21 Replacement Project Begins Next Week

News Release

October 19, 2017 – Calgary – National Energy Board

The National Energy Board’s (NEB) oral hearing on a proposal from Enbridge Pipelines (NW) to replace a segment of the Line 21 Pipeline begins on Monday, October 23 at the Fort Simpson Recreation Centre at 9 a.m.

The hearing will start with Oral Traditional Evidence from four Indigenous groups. Once the Oral Traditional Evidence portion of the hearing has finished, intervenors will have the opportunity to cross-examine the evidence of other hearing participants. The oral hearing will conclude with final argument.

The schedule of speakers, which is subject to change, is available on the NEB’s website. While the public is welcome to attend, only those who have already registered will be able to participate in the hearing.

The Mackenzie Valley Land and Water Board (MVLWB) is also considering the potential environmental and socio-economic effects of the project under the Mackenzie Valley Resource Management Act. The NEB and the MVLWB have committed to coordinate the two regulatory processes where possible. The MVLWB will begin its hearing on Friday, October 27, after the NEB’s hearing wraps up on October 26.
