We are planning to construct a new eight-inch steel transmission pipeline that runs approximately 36.6 km from east of Dominion City to north of Altona. This project will connect to an existing pipeline system to address gas capacity constraints from new business development in the area. The project will also require:
- expansion of the existing gate station east of Dominion City, the point of connection (i.e., tie-in) to TC Energy
- two new control points and the decommissioning of one existing control point
- expansion of two existing control points
The proposed pipeline traverses the Rural Municipalities of Emerson-Franklin, Montcalm, and Rhineland, and is located on Treaty 1 lands, the original territories of the Anishinaabeg, Anishininewak and Ininewak, and the National Homeland of the Red River Métis. We acknowledge these nations who have occupied and cared for these lands for thousands of years and their longstanding cultural and spiritual connections with the land. Through this we recognize the importance of learning and considering the unique perspectives these nations share throughout the project.
Construction methods for this project include Trenching and Horizontal Direct Drilling (HDD). Trenching involves excavating the ground and placing the pipeline within the excavated area. A typical trench depth is 1.3 meters, and the top of the pipe lays 1 meter below the surface. HDD is used to install the pipeline where it crosses drains, railways and roadways. HDD is a technique used to install underground utilities, like pipelines. A tunnel that follows an arc shape is drilled under the designated area, and the pipeline is pulled through the drilled underground tunnel, resurfacing on the opposite side.
This project is classified as a Class 2 development under The Environment Act. An environmental assessment report has been developed and submitted for this project.
