NOVA Gas Transmission Ltd. – West Path Delivery 2023

Project Information

NOVA Gas Transmission Limited (NGTL) has filed a Project application for the West Path Delivery 2023 (Project). The proposed Project includes the construction and operation of approximately 40.1 km of 48 inch nominal pipe size (NPS) inthree sections, including:

Description of three sections
Pipeline section Length Location
Western Alberta System (WAS) Mainline Loop No. 2 Turner Valley Section (Turner Valley Section) 23.7 km Approximately 3 km northwest from the Town of Turner Valley, AB
WAS Mainline Loop No. 2 Longview Section (Longview Section) 9 km Approximately 30 km southwest of the Town of High River, AB
WAS Mainline Loop No. 2 Lundbrek Section (Lundbreck Section) 7.4 km Approximately 30 km northwest of the Town of Pincher Creek, Alberta

If the Project is approved and built, some temporary infrastructure, such as access roads, will be required during construction.

The Project parallels existing infrastructure (such as the existing NGTL pipeline right of way, other pipeline right of ways, powerline easements and road allowances) for approximately 75% of the route. The Project will traverse approximately 5 km of Crown land and 34 km of private freehold land. The Project will require new permanent land rights. Temporary workspace is also anticipated to be required for the Project construction.

NGTL’s current plans, if approved, are to start construction in the third quarter of 2023, with construction being completed in November 2023 and an anticipated in-service date of November 2023.

Crown Consultation

A primary forum for the CER to fulfill the Crown’s consultation obligations to Indigenous Peoples has been through its Commission’s hearing process. In addition, in its role as the federal Crown Consultation Coordinator (CCC) for this project, the CER conducted supplemental Crown consultation activities with potentially affected Indigenous communities and coordinated collaboration with other government departments and NGTL, as necessary.

The CER Crown Consultation and Accommodation Report, which describes the outcomes of the CCC consultation process and activities, was developed based on consideration of the Commission’s Recommendation Report (Commission Report), the information and evidence available through the Commission’s hearing process, and supplemental consultations undertaken between the CCC and potentially affected Indigenous communities.
