Peace River Mainline Retirement Program

Natural Gas Icon


After many years of service, the 266 km (165 mile) south section of the Peace River Mainline (part of the NGTL System) will be retired. As with any asset nearing the end of its life cycle, part of our ongoing commitment to the safe, responsible shut down includes regularly conducting meetings with nearby landholders and Indigenous communities to gather their input.

On March 14, 2018, after a comprehensive review of the technical and environmental aspects of the project, the National Energy Board approved TC Energy’s application.

We also undertake a comprehensive review of the technical and environmental aspects of the area once the pipeline has reached the end of its life cycle.

For more information, read our Peace River Mainline Abandonment fact sheet.

Indigenous communities

Maintaining strong relationships with Indigenous communities near our projects, assets and facilities is an integral part of our business. As such, ongoing community dialogue is playing a large role in our plans to remove 9.3 km (5.8 miles) of pipeline from Sturgeon Lake Cree Nation Reserve lands. The adjacent map illustrates the section of pipeline to be removed.

Environmental care

As part of our plans, we’ve filed a comprehensive plan to ensure the land is restored to its natural state where possible. Known as an Environmental and Socio-Economic Assessment (ESA), this plan identifies the potential impacts on a number of factors including:

• Vegetation
• Wildlife
• Water crossings
• Cultural and archaeological sites
• Potential benefits of employment and contracting

If required, more specific environmental mitigation strategies are outlined in our Environmental Protection Plan.


Our company pays property taxes on the south section of the Peace River Mainline in five Alberta municipalities: Clear Hills County, Birch Hills County,  the Municipal Districts of Northern Lights, Peace and Greenview and on Sturgeon Lake Cree Nation lands.

Once regulatory work related to the Peace River Mainline End of Life Cycle Program is complete, the licensed lines will be removed from our property tax assessment.

The section of the pipeline we will be removing is located approximately 34 km west of Peace River. It sits between the Meikle River and the Valleyview compressor stations in Clear Hills, Northern Lights, Peace, Birch Hills and Greenview counties.

In everything we do, we take significant steps to protect the land and environment. A comprehensive Environmental and Socio-Economic Assessment (ESA) for the Peace River Mainline Retirement Program has been prepared and filed to support our application for abandonment.

The ESA identifies and assesses potential impacts on the natural and human environment likely to be associated with the project. This includes effects on:

  • Vegetation
  • Wildlife
  • Water course crossings
  • Cultural and social resources
  • Potential benefits from employment and contracting

If needed, specific project mitigation strategies will also be developed as part of the Environmental Protection Plan. Where facilities are removed, TC Energy will reclaim the land as part of the abandonment process. Facilities left in place will remain in our database and all responsibility associated with the facilities will be maintained.

As part of planning for the south section of the Peace River Mainline, we developed end-of-lifecycle plans for submission to the NEB. These reflected input from interested parties, including landowners. The plans help determine the appropriate approach for the facilities to minimize impact on landowners, communities and the environment.

The application includes removal of the above-ground facilities including buildings, yard piping and unnecessary fencing. Additionally, some associated below-ground pipelines will be removed. This involves fully cleaning the pipeline, cutting the line in select locations and capping sections of the line to safely leave them buried in the ground.

NEB hearings for this application took place between February 22 and March 16, 2017.

Building and maintaining relationships with Indigenous communities near our projects and existing facilities has long been an integral part of how we do business. We respect the diversity of Indigenous cultures and their ties to the land. That’s why we work with First Nations communities to identify the potential effects of our activities and find mutually satisfactory outcomes.
