What is Line 5 2 Line 5 is an Enbridge pipeline that was built in 1953. The line runs for 645 miles from Wisconsin, under the Straits of Mackinac, through Michigan to Sarnia, Ontario. It was built to high safety standards, and Enbridge maintains Line 5 with regular inspections, and the introduction of new measures that help ensure the line continues to safely transport the light crude oil and natural gas liquids that help to fuel quality of life for people in Michigan. 3 Line 5 at a glance Inspection Safety Pipeline Contents Operations The pipeline is Line 5, along with the Line 5 transports natural The line is operated regularly examined rest of our pipeline gas liquids (NGLs) and at less than 25% of using state-of-the-art system, is monitored light crude oil.

In 1953, it was built to extraordinary standards, using the finest engineering expertise from across the United States. The twin pipelines under the Straits have not experienced any leaks in six decades of operation—a testament to their design, construction, and maintenance regimen. The Bechtel Corporation, the University of Michigan’s Department of Naval Architecture and Marine Studies, and Columbia University’s Civil Engineering Department were involved in the engineering, design, and construction process. To promote the safety and integrity of the crossing, support anchors have been constructed and placed along the section of Line 5 that runs beneath the Straits of Mackinac. While federal regulations allow for a span of up to 140 feet between underwater support anchors, Enbridge committed to further enhancing the safety of the crossing by placing additional anchors beneath the Straits crossing. Today, the Line 5 Straits crossing has 181 support anchors, none of which are more than 75 feet apart, with plans to install 20 more through 2020. — — — — The Straits crossing is Hydrographic surveys, The pipes are heavier- The pipes consist of comprised of two 20-inch test boring and echo walled (a minimum of specially manufactured parallel pipelines which soundings of the area 0.812 inches), the thickest steel—the same steel are secured deep were used to find the in our North America- used to build the iconic underwater. safest location for wide system, and still Mackinac Bridge. the pipes. exceed today’s regulatory requirements. 5 Key safety, design and operation features help to ensure Line 5’s ongoing integrity. — — — — The pipes are coated The pipes never operate Bechtel Corporation, The line is regularly from the outside with at maximum pressure. which built the Hoover inspected by divers, waterproof enamel, Less than 25% of the Dam, managed the Remote Operated then made even stronger pipe’s capacity is used engineering, procurement, Vehicles (ROVs), with a fiber wrapping. to ensure safety. and construction of Autonomous Underwater the pipeline.

We appreciate the dialog that has already occurred to provide some clarity and understanding in relation to the information requests that accompanied your letter of April 29, 2014. In order to fully understand the current situation and our responses to the information requests, I would like to provide some background information to you about the history of Line 5’s Straits crossing, about Enbridge’s operations, and about the significant economic benefits Enbridge’s Line 5 has brought Michigan and its citizens since it entered service in 1953. Historical Facts about Line 5 In 1953, one of the greatest pipeline engineering achievements of its time was completed with the construction of a new 30-inch pipeline from Superior, Wisconsin to Sarnia, Ontario, and also serving Michigan. One of the most notable achievements during construction of this 645-mile line was the 4.6-mile crossing of the Straits of Mackinac in up to 220 feet of water. While such a long crossing had not been attempted before, engineering specialists from Bechtel, the Department of Naval Studies of the University of Michigan, as well as specialists from Columbia University came together to address the challenge.

I live near the Straits, so this is very personal for me. I do not want to see my home turned into an industrial zone to meet Canada's energy needs. I am also someone who respects the sanctity of the land and the water. The tunnel would literally be a rape of the Straits. Given the grim realities of climate destabilization, for the State of Michigan to enable a massive investment in fossil fuel infrastructure, the energies that are stealing the future of our children and grandchildren, is perverse. The construction of a tunnel not maintenance as suggested. This tactic is an industry strategy that's been proven successful in skirting legal protections. We saw that after Enbridge's dilbit spill on the Kalamazoo River.

  • Michigan Crude Oil Production: Alternatives to Enbridge Line 5 for Transportation
    MICHIGAN CRUDE OIL PRODUCTION: ALTERNATIVES TO ENBRIDGE LINE 5 FOR TRANSPORTATION Prepared for National Wildlife Federation By London Economics International LLC 717 Atlantic Ave, Suite 1A Boston, MA, 02111 August 23, 2018 Michigan crude oil production: Alternatives to Enbridge Line 5 for transportation Prepared by London Economics International LLC August 23, 2018 London Economics International LLC (“LEI”) was retained by the National Wildlife Federation (“NWF”) via a grant from the Charles Stewart Mott Foundation, to examine alternatives to Enbridge Energy, Limited Partnership (“Enbridge”) Line 5 for crude oil producers in Michigan. About sixty-five percent of the crude oil produced in Michigan currently uses Enbridge Line 5 to reach markets. This production is located in the Northern and Central regions of the Lower Peninsula. Oil production from the Southern region of the Lower Peninsula does not use Enbridge Line 5 to reach markets. LEI’s key findings are that the lowest-cost alternative to Enbridge Line 5 would be trucking from oil wells to the Marysville market area. LEI estimates that the increase in transportation cost to oil producers in the Northern region would be $1.31 per barrel based on recent oil production levels and recent trucking costs. For the Central region, the cost increase on average would be less, as these producers are located closer to markets. There would be no impact on Southern region producers. The $1.31 per barrel cost increase amounts to 2.6 percent of a crude oil price of $50 per barrel. It is much smaller than typical monthly swings in Michigan crude oil prices, which have ranged from $28 per barrel to over $100 per barrel from 2014 through 2017.

  • Enbridge's Line 5
    MEDIA Enbridge’s Line 5 BACKGROUNDER June 2021 The pipeline’s ongoing environmental risks to the Great Lakes and the climate Context Line 5 is a 68-year-old pipeline operated by Enbridge Energy. It carries up to 540,000 barrels-per-day or 87 million litres of oil and natural gas liquids per day, from Superior, Wisconsin, to Sarnia, Ontario, taking a shortcut through Michigan and along the lake bottom of the Straits of Mackinac. As the pipeline travels through the Straits of Mackinac it diverges into two, 20-inch-diameter, parallel pipelines. This is why people sometimes call the Line 5 pipeline system the “dual” or “twin” pipelines. Figure 1. Map of Line 5 pipeline route1 ENVIRONMENTAL DEFENCE CANADA Media Backgrounder: Enbridge’s Line 5 1 The Mackinac Straits section of Line 5 with a design lifetime of 50 years, has been plagued by a series of issues, ranging from missing protective coating to three dents left by an anchor strike just this past April. It lies in what University of Michigan researchers have called “the worst possible place for an oil spill” in the Great Lakes.2 The Great Lakes are of utmost importance to protect as they hold 21 per cent of the world’s surface freshwater and 84 per cent of North America’s surface freshwater.3 Most of the liquids shipped on Line 5 are delivered to the Sarnia terminal; from there, they supply refineries in Ontario and as far east as the Quebec cities of Montreal and Levis.4 After the anchor strike in April 2020, and ensuing concern about a spill from Line 5, Enbridge proposed to build a tunnel under the Straits of Mackinac to house this leg of Line 5.

  • The Line 5 Pipeline Plays a Critical Role in Ensuring the United States and Canada Continue to Have Access to Affordable Fuels, Propane and Other Refined Products
    The Line 5 pipeline plays a critical role in ensuring the United States and Canada continue to have access to affordable fuels, propane and other refined products. Union, political and business leaders on both sides of the border are emphasizing the critical role of the Line 5 pipeline and calling for it to remain open until its replacement can be completed: “The USW strongly supports both the Line 5 replacement segment project and the continued operation of the existing pipeline … Hundreds of USW members and their communities depend on the good, family-sustaining jobs Line 5 supports.” United Steelworkers Union, February 1 “We support the pipeline and the tunnel, because Line 5 couldn’t be more important to the Lansing region. Line 5 supplies the fuel our local communities use to power the manufacturing sector and chemistry industry, to run equipment farmers use to put food on our tables, and it even delivers more than half the propane used in Michigan — not just in the Upper Peninsula. We encourage the governor and lawmakers to protect the jobs and investment our communities count on each day. We encourage them to keep Line 5 open and to back the Great Lakes Tunnel.” Business manager of UA Local 333 and President of the Lansing Regional Chamber of Commerce, March 10, 2021 “We continue to advocate for Line 5. We recognize how important it is to ensure energy security to both Canadians and Americans. … Line 5 is a vital source of fuel for homes and businesses on both sides of the border. That is something we have argued strongly, and will continue to argue strongly, with members of the U.S.
