Project Information

  • Enbridge proposes to replace 32 kilometres (km) of existing 12 inch-diameter Line 10 pipe with 35 km of new 20 inch-diameter pipe in southern Ontario. It would connect Enbridge’s Westover Terminal to its Nanticoke Junction Facility in the City of Hamilton. The Project includes three new sections for proposed reroutes from the existing right-of-way totaling approximately 11 km.
  • Enbridge applied [Filing A74506] and [Filing A74508] under Section 58 of the NEB Act for approval to construct and operate this section of the replacement Line 10 pipeline, and under Section 45.1 of the National Energy Board Onshore Pipeline Regulations to decommission this section of the Line 10 pipeline that is being replaced.
