How We Respond
For Enbridge, our primary duty is to protect the safety of people and the environment while safely delivering the energy we all count on. That means anticipating and addressing potential problems to prevent incidents long before they occur. This approach guides every one of our decisions, actions and interactions as we plan and build new projects, and as we operate and maintain our systems, every day.
Case Study
Implementing further safeguards for a safer pipeline
For more than 65 years, Enbridge’s Line 5 has transported oil and natural gas liquids without incident through the bustling Straits of Mackinac, providing crucial energy to industries and residents in Michigan.
Line 5 was engineered with the environment in mind and operates under the most extensive risk management system anywhere across our entire system.
Yet in the Enbridge view, Line 5’s pristine record of safe energy delivery just reinforces the need to proactively monitor, inspect and ensure its continuing fitness for service.
To this end, Enbridge has committed $500 million for the construction of a tunnel beneath the Straits to house a replacement of the line where it crosses the Straits, to further reinforce and protect Line 5’s outstanding safety track record.
This solution will reduce chances of a leak to near-zero, adding multiple layers of protection by placing the pipeline in a tunnel with one-foot-thick concrete walls. In addition, with the tunnel running 100 feet below the lakebed, the chances of an anchor strike from passing vessels will be fully eliminated.
While the project progresses, Enbridge has implemented additional safeguards to ensure safe operation until the tunnel is built.
One of those safeguards was the addition in October 2019 of two support vessels that monitor Straits traffic. On patrol 24/7, the vessels employ forward-looking infrared (FLIR) cameras at night to confirm that ship anchors are stowed.
In addition, a communication and monitoring system identifies approaching shipping vessels and reminds them of the no-anchor zone in the Straits to further reduce the risk of a strike.
High-resolution onshore cameras provide further around-the-clock monitoring of marine traffic to act as an early-warning and notification system.
Enbridge President and CEO Al Monaco made note of these additional safety barriers during an address last October to the Canada-United States Business Association in Detroit, highlighting the Enbridge view that environmental protection and providing critical energy supply is not an either-or proposition.
“The prime example of how seriously we take this crossing, and the environment, and the Great Lakes, is the Line 5 tunnel,” he said. “Still, we continue to add more measures to reduce risk further until and while the tunnel is being built.”
Your role in safe energy delivery
How you can help
Enbridge’s highest priority is—and always must be—the safety of the public, the communities where we live and work, of the approximately 13,600 members of our team across North America, and of the environment.
Every member of the Enbridge team strives to transport, generate and deliver the energy North America relies on as safely as possible. You have a role to play in the safe and reliable operation of the energy systems that power our communities and society as well.
There are two key ways you can contribute to the safety and reliability of Enbridge’s systems in your community. First, make sure to call or click before you dig.
It’s free, helps prevent accidental damage to our systems and could save your life.
In the United States call 8-1-1, and in Canada visit clickbeforeyoudig.com, two to three working days before you plan to do any excavation—from landscaping activities like planting trees, digging a new garden or building fences, to clearing brush or larger construction work—so that a locator can visit and mark underground utilities.
Second, be aware of the warning signs of a pipeline or gas distribution system leak and know what to do to stay safe in the event of an emergency.
