Line 26 Optimization

Enbridge is proposing to undertake work to optimize its Line 26 pipeline. This work, known as the Line 26 Optimization Project, would enhance the operation of the Line 26 pipeline and enable a new connection into the Dakota Access Pipeline (DAPL).

This work could help to ensure low or stable energy prices for consumers, enabling greater energy and everyday affordability. It could also help to improve energy security.

Potential Project Overview

This project would enhance the operation and transportation capabilities of the Line 26 pipeline by making the following changes:

Flow Direction

The Project would reverse the Line 26 pipeline to a North to South flow direction.

Additional Pipeline Connectivity

To connect Line 26 pipeline to DAPL, Enbridge would use parts of the existing Line 26 pipeline, along with the addition of a new pipe. This would involve Enbridge:

• Continuing to operate the existing 16-inch pipeline from the Cromer Terminal in Manitoba (MB) to the Steelman pump station in Saskatchewan (SK).
• Constructing a new 24-inch pipeline segment to replace the existing 12-inch pipeline starting at the Steelman pump station. This new 24-inch pipeline segment would cross the Canada/U.S. border and be constructed along an optimized route to connect to the DAPL Ramberg Terminal in North Dakota (ND). It would be approximately 128 kilometers (80 miles) in length of which approximately 32 kilometers (20 miles) would be in SK and approximately 96 kilometers (60 miles) would be in ND.
• Decommissioning the existing 12-inch pipeline from the Steelman Station to approximately 800 meters (0.5 miles) south of the Canada/U.S. border and maintaining but not operating the remaining 12-inch pipeline to the Berthold Terminal in ND.

Pump Station Modifications

In conjunction with the Project’s pipeline optimization work, new pump stations would be required along with modifications to existing pump stations. This work would include:

• A new initiating pump station located within Enbridge’s existing Cromer Terminal in MB
• A new midpoint pump station located near Alida, SK
• Equipment modifications at Enbridge’s existing Steelman pump station in SK

Line 26 Potential Routing

The route of the new segment of the Line 26 pipeline is still being determined, and Enbridge is interested in working with landowners, communities, Tribal Nations, First Nations and Métis governments to assess the best potential route for this pipeline.

In Canada, routing is expected to follow the existing Line 26 pipeline to minimize disruptions to landowners, area residents, and the environment. This section of pipe is anticipated to be approximately 32 kilometers (~20 miles) in length.

In the U.S., the new segment of pipe is expected to follow the existing Line 26 pipeline up to a new valve on the south side of the Canada/U.S. border, at which point a new optimized route would be used to connect directly to the Ramberg Terminal in ND. This section of pipe is anticipated to be about 60 miles (~95 km) in length.
