Dawn to Corunna Replacement Project

Enbridge Gas Inc.

Enbridge Gas Inc. has applied to the Ontario Energy Board for approval to construct a natural gas pipeline and ancillary facilities in the Township of Dawn-Euphemia and St. Clair Township.

If the application is approved as fi led, Enbridge Gas Inc. will retire seven compressor units located at its Corunna Compressor Station in St. Clair Township and replace their capacity by installing approximately 20 kilometres of Nominal Pipe Size 36-inch natural gas pipeline from its Dawn Operations Centre in the Township of Dawn-Euphemia to the Corunna Compressor Station. The project also includes station work at the Dawn Operations Centre and the Corunna Compressor Station, required to tie-in the new pipeline.

Enbridge Gas Inc. has also applied for approval of the forms of agreement it offers to landowners to use their land for construction of the proposed pipeline. 

Enbridge Gas says that the project is needed because it is experiencing increasing compressor downtime and reliability issues due to compressor unit obsolescence.

The Dawn Operations Centre and the Corunna Compressor Station are the two main compression locations for Enbridge Gas’s Dawn Hub. The location of the proposed pipeline is shown in the map.
