In order to maintain the safe and reliable operation of Enbridge Gas’s system, and to continue meeting the natural gas needs of our customers, we are replacing some of our older natural gas storage and transmission assets in the in St. Clair Township area. The proposed project includes decommissioning up to seven of 11 natural gas compressors currently located at the Corunna Compressor Station, which are approaching the end of their lifecycles. The project includes the construction of a new 36-inch diameter steel pipeline between the Corunna Compressor Station in St. Clair Township and the Dawn Operations Centre in the Township of Dawn-Euphemia. The project is subject to Ontario Energy Board (OEB) approval and if approved, construction would begin in mid-2023 and be complete by the end of 2023.
