Rockcliffe Control Station Relocation Project

The Rockcliffe Control Station is a natural gas pressure regulation station that safely reduces the pressure of natural gas that is delivered from the Enbridge Gas St. Laurent pipeline to serves Ottawa and Gatineau.

This station was originally installed on the Ontario side of the Ottawa River in 1985 to address reports of low natural gas pressure in Aylmer, Québec. To ensure the continued safe and reliable delivery of natural gas to customers in Ontario and Quebec, Enbridge Gas is proposing to relocate the station from its current location and rebuild it to encompass the infrastructure updates required to meet current safety and engineering design standards and requirements.

The proposed Project is located on lands administered by the National Capital Commission (NCC) and is therefore subject to a Federal Land Use, Design and Transaction Approval (FLUDTA) under the National Capital Act. The Project also triggers Section 82 of the Impact Assessment Act, which requires that projects proposed on federal land are reviewed by a responsible federal authority to determine if they are likely to cause significant adverse environmental effects.

This Project includes components owned by Enbridge Gas Inc., doing business as Enbridge Gas Ontario and regulated by the Ontario Energy Board (OEB), as well as components owned by Niagara Gas Transmission Limited and regulated by the Canada Energy Regulator (CER). Enbridge Gas Ontario and Niagara Gas Transmission Limited will coordinate their activities for this Project as Enbridge Gas.
