The Proposed Project

Forty Mile Gas Co-operative is to execute a project to install new 3 inch polyethylene underground piping for a new natural gas pipeline section in the Village of Ralston. This roughly 895 m pipe will link regulator stations 4 and 9 to ensure that gas flow can continue if one section of the pipeline is turned off. The line will be installed using horizontal directional drilling along existing roadways to minimize environmental impacts. Forty Mile is responsible for funding and conducting the project and will retain ownership of the pipeline.
