March 2, 2018 - Construction of Line 3 is underway
Enbridge began building the Line 3 Replacement Project in August, 2017. The company plans to replace the existing 34-inch Line 3 pipeline, with a new 36-inch pipeline. Once construction of the new pipeline is complete, Enbridge will decommission the old 34-inch pipeline.
As part of the NEB’s approval of the project, we directed the company to file monthly construction progress reports. You can find these on our website.
Enbridge has divided construction of the project into nine spreads and work has begun at four of these spreads, located in Alberta and Saskatchewan. Construction of the new pipeline in three of the spreads is complete. Final clean-up activities will begin this summer. In the other spreads, construction has wrapped up for the winter. As part of the project, the company is also carrying out construction work at the Hardisty Terminal and nine pump stations.
Enbridge has also completed a trenchless crossing of the South Saskatchewan River. A trenchless crossing requires limited or no in-stream construction so will cause little to no disturbance to the watercourse bed and banks. The most common type of trenchless crossing is a Horizontal Directional Drill (HDD), which is the technique being used to cross the South Saskatchewan River.
NEB staff have been on the ground throughout the construction phase, verifying compliance with our regulations and project-specific conditions. To date, NEB inspectors have completed 16 inspections in the areas of Environment, Safety, Integrity and Security. You can view the inspection reports on our website.
Construction work on Line 3 Replacement Program, October 2017
August 1 2017- Enbridge to begin building Line 3
As part of the NEB’s review of the Line 3 Replacement Project, we attached 89 conditions to the project.
Some of these conditions apply to the project throughout its lifecycle however; approximately 20 conditions require Enbridge to file documentation with the NEB before construction can begin, including four conditions that required the NEB’s approval. You can review these documents and any related NEB correspondence here [Folder 2985609]
We determined in late July that Enbridge had satisfied the requirements for those conditions that applied to the pre-construction phase of the project and the company will begin construction in early August.
This is not the end of our involvement with this project. Our staff will be on the ground at different times throughout the lifecycle of this pipeline, inspecting the project to make sure that Enbridge is complying with the commitments they have made, the project-specific conditions and our regulatory requirements.
In fact, our compliance and verification activities have already begun: we recently completed a pre-construction audit to make sure that Enbridge had established the necessary oversight to manage safety and environmental protection during construction. We’ll make our findings public in the coming weeks.
