Located in British Columbia’s Peace River Regional District, the North Montney Mainline (NMML) is a 206 km (128 mile), 42-inch diameter pipeline, which will also include metering facilities, valve sites, and compression facilities, will provide the critical natural gas transmission infrastructure required to connect natural gas producers and downstream markets throughout Canada and the United States. The project consists of a 206 kilometre (km), 42-inch pipeline, two compressor stations, and 14 meter stations. It will begin at a the northern point of the existing Saturn section of the Groundbirch Mainline at 14-21-80-20-W6M and terminate at the Blair Creek Receipt Meter Station located in Unit 30, Block K, Group 94-G-7.[3]

TC Energy reached substantial completion of the North Montney Mainline Project (67km x 42" pipeline) in early in Q2 2019. In Q3 2019, TC Energy started the final cleanup phase of the project, which is expected to last into early Q4 2019.[4] In November 2019 analyst Tudor, Pickering, Holt & Co. estimated that the pipeline would be commissioned in January 2020.[5] All of the pipeline except for the 24-km Kahta section was commissioned in January 2020. The Kahta section was commissioned in April 2020.[6]
