Line 9A Reversal (Phase I) Overview

Line 9 Reversal Phase 1

Download PDF (157 KB)

The reversal of Line 9A, from Sarnia, Ont., to North Westover, Ont., represents the first phase of Enbridge’s Eastern Canadian Refinery Access Initiative.

With the National Energy Board having approved Enbridge’s standalone application for the reversal of the section known as Line 9A in July 2012, the Ontario refinery industry can now take advantage of a steady, secure, and more economical supply of Western Canadian crude oil.

This first step of Enbridge’s Eastern Canadian Refinery Access Initiative will help to level the playing field for Canadian refineries, safeguard jobs, and bolster the security of Canada’s energy supply at the same time.

The proposed Line 9 reversal project will use the existing pipeline, which has been operated safely and reliably by Enbridge since 1976. No new pipe will be added to complete the reversal and capacity expansion. Except for some temporary workspace, all work will take place within existing Enbridge properties and rights-of-way.

We continue to engage the public in meaningful discussions regarding the proposed Line 9 reversal. We’ve engaged with more than 2,600 stakeholders on this project. We’ve held sixcommunity open houses in Quebec, and 20 more in Ontario, along the Line 9B right-of-way. We speak frequently with individuals and organizations to provide information and answer questions, and since early 2013, we’ve responded to more than 200 questions from nearly 40 different stakeholders.

Pipeline Safety

Over the past decade, Enbridge has transported nearly 12 billion barrels of crude oil with a safe delivery record that’s better than 99.999 per cent. We also know that’s not good enough, because our goal – simply, unequivocally – will always be zero incidents.

At Enbridge, we back up our safety priorities by investing heavily in pipeline safety and maintenance initiatives. In 2012, we spent more than $800 million to ensure the safety of our pipeline system – with a pipeline integrity program that ensures our pipelines are inspected, both physically and visually, for safety and reliability. We doubled the number of staff dedicated to leak detection and pipeline control systems, and we substantially strengthened our focus on the tools, technologies, and strategies necessary to ensure the fitness of our pipelines.

Line 9 Products

Line 9 will carry mainly light crude oil. However, shippers will be permitted to ship crude oil blends or types that meet quality specifications set by Enbridge, and filed with the National Energy Board. This includes heavy crudes such as diluted bitumen – which has been studied by numerous scientific bodies, including the highly respected and influential National Academy of Sciences, and found to be non-corrosive and safe for pipelines.

At Enbridge, we’ve been transporting crude oil produced from Canada’s oil sands region since 1968. There is nothing new about transporting this form of crude oil – and after nearly half a century, there is no evidence that internal corrosion is caused by transporting oil from the Canadian oil sands. In fact, Enbridge has never experienced an internal corrosion failure on its mainline pipeline system.
