Enbridge Gas Inc. (“Enbridge”) has identified the need to abandon and replace approximately 16 km of nominal pipe size (NPS) 12 inch extra-high pressure (XHP) steel natural gas main in the City of Ottawa. The project under consideration represents Phases 3 and 4 of a four-phase plan for replacing the existing St. Laurent Pipeline. Phase 1 and 2 have been completed.
The pipelines to be abandoned will be replaced with, approximately: 9 km of NPS 12 XHP ST; 2.4 km of NPS 16 XHP ST; 4.2 km of NPS 6 intermediate pressure (IP) polyethylene (PE); and 3.6 km of NPS 4 IP PE. Various other facilities (e.g. pipelines of smaller lengths and size) will also be abandoned and replaced.
The study is being conducted in accordance with the Ontario Energy Board (OEB) Environmental Guidelines for the Location, Construction, and Operation of Hydrocarbon Pipelines and Facilities in Ontario, 7th Edition. Enbridge has applied to the OEB for approval to construct the project.
The tasks and timelines for this project are presented below:
|Selection of Study Area||Enbridge Gas assessment of current and future network demand. System analysis and network design confirm potential locations.||Spring/Summer 2019|
|Route Selection||Dillon was retained by Enbridge Gas to conduct a route analysis to go through the five step planning process:
1. Confirm study areas
2. Develop an inventory of environmental and land features within the study areas.
3. Develop routing criteria/constraints.
4. Identify constraints within the study areas.
5. Analyze the study areas by applying routing criteria to identify possible route alternatives and determine a preferred route.
|Fall 2019 / Winter 2020|
|Public Consultation||Dillon and Enbridge Gas are conducting a continuous public consultation process throughout the planning process as follows:|
|1) Meetings and / or correspondence with federal and municipal representatives and agencies, and other key stakeholders.||2020|
|2) Public Notice – a Notice of Study Commencement and Public Open House advising the public of the study, requesting information and an invitation to the Open House.||Notification Letter mailout to study area:
Week of February 10, 2020
The Ottawa Citizen and Le Droit Newspaper:
February 11 and 18, 2020
|3) Information Session - Present study area and pipeline route to the public and interested stakeholders.||February 25, 2020|
|4) Receive input from the public and stakeholders||Winter 2020|
|Preparation of Environmental Report||Prepare the Environmental Report based on collected data, consultation feedback, impact assessment, and mitigation recommendations.||January - July 2020|
|Circulation to Ontario Pipelines Coordinating Committee (OPCC)||Enbridge Gas circulates the Environmental Report with the OPCC.
The purpose of the OPCC is to coordinate the Ontario government review of facilities projects in Ontario requiring OEB approval, with the goal of minimizing negative impacts.
|Consultation||A Notice of Project Change was released to the Project Contact list.||October 2020|
|Environmental Report Amendment||An Updated Notice of Project Change and Environmental Amendment was released to the Project Contact list.||November 2020|

Indigenous and community engagement
For new construction projects, the collective input from Indigenous communities and Métis, government agencies, municipalities, stakeholders, the public and landowners play an integral role in the route and site selection process.
Prior to construction, public input is obtained to ensure that the community is advised of the proposed project, and to involve the public in the decision making process. Public consultation is a key component of the Environmental Report.
By providing the public with an opportunity to receive information about the Project, the consultation program helps identify and address stakeholder concerns, and have meaningful participation into the Project review and development process.
Public input from the Open House will be used to help finalize the project and mitigation plans to be implemented during construction.
Once the Leave-to-Construct (LTC) application is made to the OEB, any party with an interest in the Project, including members of the public, can participate in the process.
The Notice of Study Commencement and Public Open House for the St. Laurent Ottawa North Pipeline Project appeared in The Ottawa Citizen and Le Droit on February 11 and 18, 2020.
Stakeholder consultation is an important part of this study. Members of the public, regulatory agencies, and other stakeholders are invited to attend the Open House to review the project and provide comments. Details are provided below:

Notice of project change
On October 19 and 20, 2020, Enbridge Gas distributed a Notice of Project Change via email to the Project contact list for a new preferred route for Phase 4 of the pipeline, which was a hybrid of the existing preferred route and one of the alternative routes identified in the Environmental Report (June 2020). The intention was to provide stakeholders an opportunity to comment and provide input on the project change, prior to completion of the Environmental Report Amendment.
Updated notice of project change
Through continued consultation with key stakeholders, the new preferred route described in the October Notice of Project Change was revised to follow one of the alternative routes identified in the Environmental Report (June 2020). There are no proposed changes to Phase 3 of the Project.
An Updated Notice of Project Change was emailed to stakeholders on November 18, 2020 to provide stakeholders an opportunity to comment and provide input on the project change. Additionally, a link to the Environmental Report Amendment was also provided.
The St. Laurent Ottawa North Pipeline Project is regulated by the Ontario Energy Board (OEB), an independent government agency that regulates the electricity and natural gas sectors. After a public review and hearing, the OEB is in a position to approve our application. In this section, you can review all regulatory files about the project.
In accordance with the OEB's “Environmental Guidelines for the Location, Construction and Operation of Hydrocarbon Pipeline and Facilities in Ontario, 7th Edition 2016”, Enbridge Gas has retained the services of Dillon to complete an environmental assessment for the proposed project.
The purpose of the environmental assessment is to: identify any potential impacts of the proposed project on the social, economic and natural environments; identify local or provincial concerns regarding the proposed project; determine preferred routing of the pipeline segments (and if alternate routing is practical); gather input from agencies, stakeholders, Indigenous communities and Métis, affected landowners, and the public. As well, mitigation measures are recommended to limit impacts on the social, economic and natural environments. It is important to minimize potential impacts of the proposed natural gas distribution pipelines and associated facilities on the environment. The data, analysis and results of the environmental assessment are detailed in the environmental report.
Enbridge Gas has adjusted the sequence of pipeline segments for each of the original Phases 3 and 4 within this Updated Application and pre-filed evidence to reflect the latest planned in-service dates while continuing to prioritize completion of, and conversion of existing customers to, the new IP PE system (previously defined as Phase 3 segments) ahead of the completion of the new XHP ST system (previously defined as Phase 4 segments) and abandonment of existing natural gas mains. Importantly, no pipeline segments have been added or removed as part of this Updated Application. Instead, the sequence of segments has been adjusted for each of Updated Phases 3 and 4 to reflect their planned in-service dates (ISDs) (i.e. Updated Phase 3 = 2022 ISDs; Updated Phase 4 = 2023 ISDs).
