Sarnia Industrial Pipeline Reinforcement Project

Natural gas flames in a furnace

Project Phase: Environmental Studies

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

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

Please note: as of Jan. 1, 2019, Union Gas and Enbridge Gas Distribution have amalgamated into one utility with the legal name Enbridge Gas Inc.

The project is subject to approval by the Ontario Energy Board (OEB). We plan to file an application with the OEB as early as the summer of 2019. If approved by the OEB, construction of the proposed project is planned to begin as early as spring 2021, with an in-service date of fall 2021.
