PROPOSED ST. LAURENT PIPELINE PROJECT

NOTICE OF STUDY COMMENCEMENT AND OPEN HOUSE

CITY OF OTTAWA, ONTARIO ENBRIDGE GAS INC. The Study

Enbridge Gas Inc. (Enbridge) has retained Dillon Consulting Limited (Dillon) to undertake an environmental and cumulative effects assessment and Environmental Report (ER) for the installation of approximately 1.7 kilometers (km) of pipeline along St. Laurent Boulevard, in the City of Ottawa. Enbridge has identified the need to replace the existing pipeline on St. Laurent Boulevard due to the current pipe conditions and to better service 140 customers by transferring customers to an intermediate pressure (IP) system. Once the study is complete, Enbridge may apply to the Ontario Energy Board (OEB) for approval to install the existing pipeline. If approved, construction may be scheduled for the summer of 2019. The preferred route for the proposed natural gas pipeline originates approximately 20 m south of Donald Street of St. Laurent Boulevard, continuing north on St. Laurent Boulevard for approximately 1.7 km where it will terminate approximately 20 m north of Montreal Road. It should be noted that no alternatives could be considered as this pipeline will be servicing customers directly along the route. The pipeline will consist of nominal pipe size (“NPS”) 6 IP polyethylene natural gas main. The pipeline is planned to be located mainly within municipal road rights-of-way, and will require short tie-ins to the existing network at road intersections at McArthur Avenue, Coté Street, and Noranda Street. The preferred route is identified on the map.

The Process

The study is being conducted in accordance with the OEB’s Environmental Guidelines for the Location, Construction, and Operation of Hydrocarbon Pipelines and Facilities in Ontario. The study will review the need and justification for the pipeline, describe the natural and socioeconomic environment, evaluate the project from a social and environmental perspective, outline safety measures, and describe appropriate measures for impact mitigation and monitoring.
