Sarnia Industrial Pipeline Reinforcement Project

Natural gas flames in a furnace

Project Phase: Regulatory Approval

Demand for natural gas from industries in the Sarnia area is increasing. As a result, Enbridge Gas is constructing a new natural gas pipeline between our existing Dow valve site and Bluewater interconnect transmission stations in the Township of St. Clair.

The pipeline will be 20 inches in diameter, and approximately 1.2 km in length. Please view a map of the project.

The project was approved by the Ontario Energy Board (OEB). Construction is planned to begin as early as spring 2021, with an in-service date of fall 2021.
