Project Information

In its application, which was filed on 8 August 2011 under section 58 of the National Energy Board Act, Enbridge is asking the NEB to approve the additions and modifications required to allow the reversal of crude oil flow within a segment of Line 9 - a 762-millimetre (30 inches) outside diameter crude oil pipeline - from the Sarnia Terminal to the North Westover Station in southwestern Ontario.

All proposed work would take place on existing Enbridge facilities and surface leases, with no planned ground disturbance along the pipeline right-of-way.

The shift in flow direction from west to east would see the pipeline revert back to the direction that was originally approved in 1975. The current westward flow has been in place since 1999.
