2018 Greater Sudbury Lateral Replacement

Family uses natural gas

Project Phase: Environmental Studies

Union Gas is proposing to replace portions of the Greater Sudbury Lateral Pipeline System to ensure the continued reliable delivery of natural gas and serve an increased demand in Greater Sudbury and surrounding area.

The proposal would involve removing an existing 10-inch diameter pipeline and replacing it with approximately 20 kilometres of new 12-inch pipeline.

Key Facts

  • Natural gas an affordable source of energy
  • Project supports growing demand in area
  • Public consultation a priority
  • Safety always top of mind

The proposed project will occur in two sections: the first between the existing Union Gas Coniston and Frood Road Stations, and the second between the Union Gas Azilda and Walden Stations. (Please see the "Notice of Project Commencement" showing the location of the project.)

Ontario Energy Board (OEB) review and approval is required before this project can proceed. Union Gas will submit a Leave-to-Construction application to the OEB in the spring of 2017. If approved by the OEB, construction of the project is planned to begin in the spring of 2018.

A key part of the planning process involves consultation with local landowners, First Nations and Métis communities, government agencies, project neighbours, and other stakeholders that could be impacted by the project. Union Gas will engage interested parties through project notices and letters, individual meetings/phone calls, where requested, regular website updates, and through an information session.

Environment a priority

Union Gas is committed to minimizing the effects of our projects and operations on the environment.

AECOM was retained by Union Gas to prepare an Environmental Report to assess any potential environmental and socio-economic effects that may result from the project and outline plans for avoiding and/or mitigating any effects, where possible. Examples of potential environmental considerations that will be assessed in the report include, but are not limited to:

  • Existing land uses, local residents and businesses
  • Designated natural areas, woodlots, wetlands and other vegetation (e.g. hedgerows)
  • Wildlife and wildlife habitats
  • Watercourses and waterbodies, aquatic species and habitats
  • Species at Risk
  • Groundwater resources
  • Soils, bedrock geology and extractive resources (aggregates)
  • Archaeological resources and built heritage

The Environmental Report was prepared in accordance with the OEB's Environmental Guidelines for the Location, Construction and Operation of Hydrocarbon Pipelines and Facilities in Ontario (2016). The report will accompany the Leave-to-Construction application that will be submitted to the OEB. Please view the main Environmental Report here, and check out the appendix as well. (Note: The appendix file contains numerous high-resolution graphics and may take several minutes to load.)

The local community will benefit from the incremental taxes that Union Gas will pay annually. As the project progresses, experienced pipeline contractors will use local resources to build the pipeline and, where possible, procure materials from the local community.
