CALGARY - Enbridge Inc. says it expects its newly reversed Line 9 pipeline between southwestern Ontario and Montreal will come into service by the end of June.

Spokesman Graham White says the company plans to ask the National Energy Board for permission to open the pipeline within the next day or two.

The pipeline was to have started up in November, but was delayed when the federal energy regulator flagged concerns about the protection of water crossings along the route.

The NEB had questioned the way in which Enbridge decided where to place valves shutting off the flow of oil in relation to water crossings.

But the NEB now says Enbridge has demonstrated its approach is appropriate, with a total of 62 valves along the pipeline.

However, Enbridge is required to submit more information to the watchdog within the next year to ensure the pipeline is operated safely during its lifespan.
