Peace River Mainline Retirement Program


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 TransCanada’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.

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.
