As a Concerned Resident of Michigan, I Am Asking That You Please Deny The From: Sherri Valdes To: LARA-MPSC-EDOCKETS Subject: Case No. U-20763 Date: Tuesday, May 12, 2020 12:37:47 PM As a concerned resident of Michigan, I am asking that you please deny the application for Enbridge Energy's proposed Line 5 tunnel project under the Straits of Mackinac. We can no longer allow Enbridge to endanger our precious waterways and resources. Regards, Sherri Valdes Howell, Michigan Sent from my Samsung Galaxy smartphone. From: Deb Hansen To: LARA-MPSC-EDOCKETS Subject: Comments Regarding Case No. U-20763 Date: Tuesday, May 12, 2020 11:46:52 AM RE: Case U-20763 Dear MPSC Commissioners, I am writing to ask you to reject Enbridge Energy’s request for a declaratory ruling that they do not need MPSC approval for their proposal to move forward with a tunnel at the Straits of Mackinac. 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. They were allowed to double the capacity of Line 6B from Stockton to Sarnia by doing it in segments without an environmental review. Will that happen again here? As a new project, the tunnel is subject to the Great Lakes Submerged Lands Act. This act is there to help us make wise decisions by considering the bigger picture. Will we have the courage to stand up against the most powerful industry on earth in order to protect life, the sacred sources of life, and health? I would be encouraging you to deny this request if we were not dealing with a pandemic. To give the go-ahead now when so many people have concerns about meeting their basic needs, is not where we should be focusing now. You are tasked with determining whether this project is in the public interest of the people of Michigan. Respectfully, Rev. Deb Hansen Levering, MI Virus-free. www.avast.com From: Holly Groff To: LARA-MPSC-EDOCKETS Subject: Enbridge Application Case No. U-20763 Date: Tuesday, May 12, 2020 12:42:26 PM RE: Case U-20763 Dear MPSC Commissioners, I strongly urge you to reject Enbridge Energy’s request for a declaratory ruling that they do not need MPSC approval for their proposal to build an oil tunnel in the bottomlands of the Straits of Mackinac. The 1953 easement granted to Enbridge’s predecessor, Lakehead Pipeline Co., was an easement to operate twin pipelines on the lakebed and contained no consideration of a subsurface tunnel. Further, as you are aware there is currently an ongoing lawsuit on behalf of the people of Michigan asserting among other things that the 1953 easement ought to be considered void because the potentially disastrous impact of an oil spill in the public trust waters of the Straits of Mackinac was not fully considered prior to issuance of the easement. This is obviously a new project despite Enbridge’s claims to the contrary, and your role in reviewing this project is essential to protect the Michigan public by determining whether or not this project is in the public interest and whether or not there are prudent and feasible alternatives to the proposed oil tunnel that could meet Michigan’s energy needs without the substantial risk involved. Impacts on the climate must now be taken into account with any new fossil fuel infrastructure. Twin oil pipelines sitting on the lakebed are substantially different than one oil pipeline in a subsurface tunnel. This cannot be considered maintenance, it is a substantial change in design and a new project that the MPSC has a responsibility to thoroughly review through robust public engagement and a contested case process. Please protect the Michigan residents that you serve by denying this request for a declaratory ruling and ensuring that members of the public have ample opportunity to be heard and fully engage in this process before making your determinations in this case.

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.

  • 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.

EXPERTS TAKE COMPREHENSIVE LOOK AT ENBRIDGE’S RISKY PIPELINES AND OUR ENERGY INFRASTRUCTURE EXECUTIVE SUMMARY December 14, 2015 Governor Rick Snyder’s Executive Order 2015-12 created and directed the Michigan Pipeline Safety Advisory Board (“Advisory Board”) to implement the recommendations of the Michigan Petroleum Pipeline Task Force Report (“Task Force”) on the future of oil transport through the Line 5 pipeline in the Straits of Mackinac and pipelines throughout the State of Michigan. The July 2015 Task Force Report concludes that Line 5 in the Straits presented the “most acute potential threat” of a catastrophic oil spill given the location if this 62-year old pipeline resting on Great Lakes bottomlands. The Task Force Report accordingly calls for an independent alternatives analysis, including as an alternative the decommissioning of Line 5 in the Straits for oil transport. Other reports, including FLOW’s (For Love of Water) September 2015 Expert Report, have substantiated that the transport of oil through Line 5 in the Straits constitutes an unacceptable high-level risk and imminent harm to our waters for drinking, recreation, commerce, navigation, tourism, and our Pure Michigan way of life.
