RE:

BAY MILLS INDIAN COMMUNITY’S COMMENTS ON THE SCOPE OF THE
ENVIRONMENTAL IMPACT STATEMENT FOR THE ENBRIDGE LINE 5 TUNNEL PROJECT

Gnoozhekaaning, “Place of the Pike,” or Bay Mills Indian Community (“Bay Mills”)
provides the enclosed comments on the scope of the Environmental Impact Statement (“EIS”)
that the U.S. Army Corps of Engineers is preparing as it evaluates Enbridge Energy, Limited
Partnership’s (“Enbridge”) application for a permit pursuant to Section 404 of the Clean Water
Act (“CWA”), 33 U.S.C. § 1344, and Section 10 of the River and Harbors Act, 33 U.S.C. § 403.
Enbridge seeks to construct a tunnel beneath the lakebed of the Straits of Mackinac and route a
pipeline through it so that it may operate the Line 5 pipeline. Bay Mills submits these comments
as a sovereign tribal nation, a consulting tribal nation, and a cooperating agency.
The proposed construction and the Line 5 pipeline are in an area of abundant resources
and enormous cultural, spiritual, and economic importance to Bay Mills. The gravity of this
proposal must be reflected in the scope of the EIS.

I. INTRODUCTION
Gnoozhekaaning, “Place of the Pike,” or Bay Mills Indian Community (“Bay Mills”)
provides these comments on the scope of the Environmental Impact Statement (“EIS”) that the
U.S. Army Corps of Engineers (the “Corps”) is preparing as it evaluates Enbridge Energy, Limited
Partnership’s (“Enbridge” or the “applicant”) application for a permit pursuant to Section 404 of
the Clean Water Act (“CWA”), 33 U.S.C. § 1344, and Section 10 of the River and Harbors Act, 33
U.S.C. § 403. Enbridge seeks to construct a tunnel beneath the lakebed of the Straits of
Mackinac (“the Straits”) and route a pipeline through it so that it may operate the Line 5
pipeline (the “Project” or “Proposed Project”). Enbridge proposes this Project in an area of
abundant resources and enormous cultural, spiritual, and economic importance to Bay Mills,
and the gravity of this proposal must be reflected in the scope of the EIS.
Bay Mills previously has expressed concerns about deficiencies in Enbridge’s application
materials, including missing information about the purported need for this Project,
decommissioning the dual pipelines, and cumulative environmental impacts, among other
things. Those information gaps about this Project persist and must be corrected—and Bay Mills,
other tribal nations, and the broader public must be provided an opportunity to comment on
any new information.
It is critical that the Corps prepare a comprehensive EIS that respects tribal nations and
resources. Bay Mills’ comments highlight the following essential topics that must be included in
the scope of the EIS:
•

the relationship between the EIS and the review of this Project pursuant to
Section 106 of the National Historic Preservation Act (“NHPA”), and how the
Section 106 review informs an alternatives analysis in the EIS;

•

appropriate alternatives for this EIS, including alternatives in which there is no oil
pipeline crossing the Straits;

•

related and connected actions on the Line 5 pipeline;

•

the environmental effects of an oil spill in the Great Lakes Basin as a
consequence of this Project;

•

the Project’s contributions to climate change and the way that the effects of
climate change may impact the Project; and

•

the environmental effects of Project construction and operation, including the
risk of catastrophic failure, explosion, or oil spill based on engineering design for
this first-of-its-kind tunnel, as well as construction impacts to species, wetlands,
water quality, and air quality.

Bay Mills’ comments are informed by tribal teachings and experiences, tribal leadership,
scientists with the Bay Mills Biological Services Department, and support from Great Lakes
Indian Fish and Wildlife Commission (“GLIFWC”), consulting engineers, 1 and counsel. Bay Mills
is a federally recognized Tribal Nation 2 and a sovereign nation with an inherent right to selfgovernance and self-determination, and it has a government-to-government relationship with
both the United States and the State of Michigan. Bay Mills submits these comments as a
sovereign tribal nation, a consulting tribal nation, and a cooperating agency. 3
II. THE EIS SHOULD HONOR THE DEEP CONNECTION AND PROTECTED INTERESTS OF BAY
MILLS AND OTHER TRIBAL NATIONS IN THE AREA OF LINE 5 AND THE PROPOSED
PROJECT.
Bay Mills is one of several Tribal Nations of Anishinaabe people (Ojibwe, Odawa, and
Potawatomi) with a deep connection to the lands and waters of the Upper Great Lakes.
Enbridge proposed the Project in an area of enormous importance to these Tribal Nations. Bay
Mills recognizes the Straits of Mackinac as the center of creation. The Straits of Mackinac are
more than a waterway; they are a place of ongoing spiritual significance to the way of life of
Bay Mills since time immemorial. The Straits are also home to many species, natural resources,
treaty resources, and cultural resources that are important to Bay Mills. The Project and the
Line 5 pipeline thus pose serious threats to the exercise of Bay Mills’ reserved treaty rights,
ability to preserve cultural resources, cultural and religious interests in the Great Lakes, and
economy, as well as the health and welfare of tribal citizens.
Every aspect of the Corps’ EIS process must be conducted in a way that ensures and
maintains respect towards Tribal Nations and protection of tribal resources. The potential
impacts from the Proposed Project’s construction on cultural and natural resources must be
evaluated in the EIS. This assessment must begin with the identification and recognition of
these resources, including not only specific land and water areas, sites and structures, but also
plants and animals, fish and water, and human relationships with nature and the environment,
including cultural and spiritual relationships. It must include economic and social effects, which
are interrelated with the natural or physical environmental effects. 4
A.

The Straits Are At The Center Of Bay Mills’ Creation Story.

As President Gravelle has recounted in testimony to the Michigan Public Service
Commission, the Straits are central to Bay Mills’ creation:

According to our oral histories, the creation of North America began with a
flooded Earth. The animals received instructions from the Creator to swim deep
beneath the water and collect soil that would be used to recreate the world. All of
the animals failed, but the body of the muskrat, the last animal that tried,
resurfaced carrying a small handful of wet soil in its paws. It is believed that the
Creator used the soil collected and rubbed it on the Great Turtle’s back, forming
the land that became known as Turtle Island, the center of creation for all of North
America. According to history, the Great Turtle emerged from the flood in the
Straits of Mackinac. The word “Mackinac” is derived from the original name of the
Great Turtle from the Ojibwe story of Creation. The Straits are more than a
waterway; they are a place of ongoing spiritual significance to the way of life of
Bay Mills since time immemorial. 5
The Straits of Mackinac are not only the center of Bay Mills’ creation story, but, as
addressed throughout these comments, the Straits play an ongoing central role in the lives of
Bay Mills’ citizens through ongoing reliance on the area for their livelihood, ceremony and
tradition, and identity.
B.

Bay Mills’ Identity Is Tied To The Water And Fisheries.

Water is critical to Bay Mills’ identity. Women are water keepers in Anishinaabe culture;
they maintain and protect water for their people, pray and care for the water during
ceremonies. They also pass on water teachings to the next generation. 6 If the water is
contaminated by tunnel construction, spills, or other possible outcomes, it directly affects the
ability of Anishinaabe tribal nations to maintain their historic traditions.
Fish and fishing are also critical to Bay Mills’ identity. Lake Whitefish, Lake Trout, and
other fish are used in cultural traditions for naming and for feasting in celebration of children,
ghost suppers, burial ceremonies, and other cultural traditions, and Lake Whitefish are sacred
to the Anishinaabe. 7
Fishing is a traditional and cultural practice for Michigan Tribal Nations, including Bay
Mills. 8 Over half of the Bay Mills’ citizen households rely on fishing for some or all of their
income. In addition, traditional fishing knowledge is passed down from each generation, and
fish are an important food used in ceremonies.
Within the Straits of Mackinac are numerous spawning grounds for different fish
species, including walleye and Lake Whitefish. If Lake Whitefish, Lake Trout, and other fish are

harmed by tunnel construction, the ongoing operation of the dual pipelines until the tunnel is
constructed, or an oil spill from Line 5, a critical component of the tribal livelihood and tribal
community would be impacted. The EIS needs to address this potential loss in the EIS, and it
must do so in consultation with Bay Mills and other Tribal Nations.
C.

Bay Mills Retains Tribal Treaty Rights In The Great Lakes Basin And Has Fiercely
Fought To Protect Treaty Rights And Resources.

Bay Mills is the modern-day successor in interest to the bands of Ojibwe people who
were identified by the negotiators for the United States as living near Sault Ste. Marie in the
Treaty of Sault Ste. Marie of June 16, 1820; the Treaty of Washington of March 28, 1836, 7 Stat.
491; the Treaty of Detroit of July 30, 1855; and the Treaty of Detroit of August 2, 1855. 9
Through these treaties, Tribal Nations retain all rights not expressly granted. 10
Specifically, as signatories to the 1836 Treaty of Washington, the Ojibwe and Ottawa
ceded to the federal government over 14 million acres of land and, in addition, the waters of
Lake Superior lying eastward of the Chocolay River, the northern portion of Lake Huron to the
mouth of the Thunder Bay River, the waters of Lake Michigan from Ford River south of
Escanaba to Grand Haven on Lake Michigan’s southeastern shore, and all the waters connecting
the three lakes. 11 This area, known as the ceded territory, includes a large part of the upper and
lower peninsulas and the Straits of Mackinac, and paved the way for Michigan’s statehood. 12
The Tribal Nations only agreed to this vast cession of their ancestral home upon
assurance that they would have the continued ability to exercise their inherent rights, reserved
by the Treaty, to hunt, fish, and gather throughout the ceded territory. 13 The Tribal Nations
carefully protected their traditional lifeway and its reliance on the environment’s natural
resources for food, shelter, medicines, and trade. 14 If permitted, the Project would be
constructed and would operate in the ceded territory.
Bay Mills has fought to protect its treaty rights through litigation, obtaining decisions
from the Michigan Supreme Court and a federal district court recognizing the treaty-protected
rights and limitations on the state’s power to regulate treaty-protected fishermen. 15

Treaties are the supreme law of the land. 16 Federal agencies, including the Corps, have a
trust responsibility to tribal nations. 17 Agencies cannot act to render treaties meaningless; only
an act of Congress can diminish a treaty. 18 If the resources that a treaty right depends upon are
destroyed, the right is violated. 19 A recognition of the supremacy of tribal treaty rights is
apparent in Executive Order 13175 and the Memorandum of Understanding Regarding
Interagency Coordination and Collaboration for the Protection of Tribal Treaty Rights and
Reserved Rights (“MOU”), to which the Department of Defense is a signatory. Section 3(a) of
Executive Order 13175 provides in relevant part: “Agencies shall respect Indian tribal selfgovernment and sovereignty, (and) honor tribal treaty and other rights.” 20 The MOU recognized
that “integrating consideration of tribal treaty and reserved rights into agency decision-making
and regulatory processes is consistent with the federal government’s trust responsibility to
federally recognized tribes and to fundamental principles of good government.” Treaties
themselves are “the source of legal authority to ensure that agency processes account for
reserved treaty rights.” 21 Thus, the Corps must not permit any project that will diminish Bay
Mills’ tribal treaty rights. As emphasized throughout these comments, that includes direct and
indirect harm to the Tribal Nations’ resources in the Great Lakes from Project construction or
operation, including oil spills and climate change.
Notably, Bay Mills has recognized that the Line 5 pipeline poses an existential threat to
treaty-protected rights and resources. On March 16, 2015, the Bay Mills Executive Council
adopted and approved Resolution No. 15-3-16-B, requesting that “any regulatory body with
oversight authority over the subject matter and/or geographic area to take any and all actions
reasonable and necessary to mandate and enforce the decommissioning of Line 5 at the Straits
of Mackinac.” 22 The Resolution explains its support for the decommissioning of Line 5 because
of Bay Mills’ concern about discharge of petroleum products into the Straits, as any discharge
would adversely affect fish shoaling, spawning and nursery areas in both Lakes Michigan and
Huron which encompass the most productive fishing areas in the 1836 Treaty ceded waters.

Consultation and Coordination with Indian Tribal Governments (06 Nov. 2000); and, the Office of the Secretary of
Defense, Trust Responsibility and Consultation Matrix.) In carrying out its federal trust responsibility, it is the Corps’
responsibility to ensure that tribal “treaty rights are given full effect,” including denying a permit for a project that
would impair treaty rights. Nw. Sea Farms, Inc. v. U.S. Army Corps of Eng’rs, 931 F. Supp. 1515 (W.D. Wash. 1996).

Moreover, a catastrophic oil spill into the Straits would devastate the aquatic ecosystem,
damage the shorelines, and disrupt, degrade, and diminish the tribal fishery reserved by treaty.
This Resolution recognized that “the human and natural ecosystems of the Straits of Mackinac
are both too complex and too fragile for a replacement pipeline for Line 5 to be successfully
sited and constructed within the reasonably foreseeable future.” 23
More recently, on May 10, 2021, the Bay Mills Executive Council adopted and approved
Resolution No. 21-05-10A, banishing Enbridge’s dual pipelines from the Bay Mills Indian
Community reservation and the lands and waters of the ceded territory, including the Straits of
Mackinac. 24 Banishment is a traditional, historical, and customary form of tribal law that has
existed since time immemorial and is only exercised by Bay Mills when egregious acts and
misconduct have harmed tribal citizens, treaty rights, territories, and resources. Banishment is a
permanent and final action.
Banishment was based, in relevant part, on Enbridge’s demonstrated actions that it
does not honor the rights and interests of Tribal Nations. These actions include: altering
underwater archeological reports; utilizing traditional cultural practices against Tribal Nations;
and, attempting to initiate non-expert cultural survey work in the Straits of Mackinac without
informing or engaging permitting authorities. Banishment further recognized that continued
operation of the Line 5 Dual Pipelines will result in a rupture of the pipeline, causing
catastrophic damage to the lands and waters near the Straits of Mackinac, destruction of tribal
treaty rights, and harm the people who depend on the Great Lakes for their economic
livelihood, their quality of life, their cultural wellbeing, and their very existence.
D.

The Straits of Mackinac Are A Traditional Cultural Property That Merits Special
Consideration In The EIS Process.

The Straits of Mackinac are a place of deep spiritual and cultural meaning to Bay Mills,
where there are important cultural and historic resources, some of which are still being
discovered and studied. Bay Mills, the Corps and SHPO 25 all agree that the Straits of Mackinac
are a Traditional Cultural Property (or Traditional Cultural Landscape). 26 Accordingly, it is
essential that the EIS evaluate the impacts of tunnel construction on this special place and
identify ways to avoid (or mitigate) those impacts. The EIS must recognize and identify the

existence of sacred sites, culturally identified as places where significant events occurred as
well as burial or cremation places. 27
Ethnohistorian Dr. Charles Cleland described the rich history of the Straits of Mackinac
in his testimony presented to the Michigan Public Service Commission:
In the case at hand, the Straits of Mackinac area was occupied in the past by
people of several native societies, particularly the Ojibwa (Chippewa) and the
Odawa (Ottawa) and more recently by modern Euro-Americans. In the case of
Native American occupation sites, they collectively contain a record of thousands
of years of tribal history. This very ancient history is preserved only in
archaeological context. Such sites are non-renewable, so that once they are
damaged or destroyed, there are no alternative means of learning about the lives
of the native people who first settled and developed unique adaptations to the
natural environment in what is today northern Michigan.
In more recent times, the Straits area was also the scene of Euro-American
settlement during the eighteenth and nineteenth centuries; sites such as Fort
Michilimackinac and Fort Mackinac on Mackinac Island and the Pere Marquette
Mission at St. Ignace as well as their associated settlements are very valuable in
Native American, American, Canadian, French and British history as well as to the
modern historic tourism industry.
Regretfully, the archaeological sites which incorporate so many details about the
lives and cultures of previous occupants of the Straits area have long been under
dire threat of destruction due to modern development, rendering those that
remain intact of much greater importance. Fortunately, many have been
recognized by their listing on the National Register of Historic Places and Sites
which signifies their importance for our national patrimony. It would be difficult,
perhaps impossible, to find any other small area of North America that has such a
huge concentration of important historic sites. 28
Further, Dr. Cleland testified that there are 141 terrestrial archaeological sites included in the
State of Michigan’s SHPO files in close proximity to the Straits of Mackinac, including nineteen
that are listed on the National Register of Historic Places, three that are part of Historic
Archaeological Districts, and one site that has been designated as a National Historic Landmark.
These sites may be endangered by the continued operation of the Line 5 dual pipelines and the
tunnel construction. 29

As a way to protect tribal interests and the integrity of these sites, the Corps should not identify in public
materials the exact location of culturally significant sites.

More information is needed to fully understand the cultural and archaeological sites in
the Straits. SHPO characterized the discovery of significant cultural resources as a likelihood,
stating “we expect numerous additional resources to be present that have yet to be reported,
documented, and evaluated.” 30 As discussed further in the Section 106 discussion, infra at III.C,
archaeological sites within the project area, surrounding area, and downstream areas must be
identified and addressed in the EIS. The EIS must also acknowledge and describe sacred sites,
burial sites, and cremation within the project area and surrounding areas potentially affected
by the proposed project.
For the NEPA and permit evaluation processes, care must be taken to protect the
cultural sites from damage during surveys and to keep locational information confidential for
spiritual reasons, and to prevent looting and vandalism. Identification needs to be done in
consultation with and at the direction of appropriate tribal entities.
Historic and cultural resources are not simply about a moment in history; they are part
of a continuum of living knowledge. Bay Mills and its tribal citizens carry cultural practices today
and continue to honor their ancestors.
III. THE NATIONAL ENVIRONMENTAL POLICY ACT, EXECUTIVE ORDERS ON ENVIRONMENTAL
JUSTICE, AND THE NATIONAL HISTORIC PRESERVATION ACT SUPPORT A COMPREHENSIVE
EIS.
A.

Under NEPA, An EIS Should Be More Extensive Than The Proposed Project.

The National Environmental Policy Act (“NEPA”) and its implementing regulations 31
support a comprehensive EIS. NEPA requires agencies to analyze the environmental impacts of
their actions. NEPA’s implementing regulations demand that federal agencies, “to the fullest
extent possible . . . [u]se all practicable means, consistent with the requirements of [NEPA] and
other essential considerations of national policy, to restore and enhance the quality of the
human environment and avoid or minimize any possible adverse effects of their actions upon
the quality of the human environment.” 32
To achieve these objectives, NEPA requires all federal agencies—including the Corps—to
prepare an EIS for all “major Federal actions”—such as the Proposed Project—"significantly
affecting the quality of the human environment,” 33 and these rules set the broad contours for
the scope of an EIS. 34 The scope of an EIS consists of actions, including connected, cumulative,
Attachment B at 2.
The 1978 Council on Environmental Quality (“CEQ”) regulations implementing NEPA apply to this EIS. The CEQ
regulations were revised in 2020, then revised again in 2022. The Corps has acknowledged that the 1978
regulations apply here, consistent with 40 C.F.R. § 1506.13 (2022).

and similar actions; alternatives, including the no action alternative, other reasonable courses
of actions, and mitigation measures; and impacts, which may be direct, indirect, or
cumulative. 35
While the Corps’ permitting authority under the Clean Water Act and Rivers and Harbors
Act may be limited to jurisdictional waters, its NEPA responsibility is not. The Corps has
“responsibility under NEPA to analyze all of the environmental consequences of a project,” and
the scope of an EIS extends beyond jurisdictional waters. 36 The agency must look to the future.
A critical part “of an agency’s responsibilities under NEPA is to predict the environmental
effects of [a] proposed action before the action is taken and those effects fully known,” 37 thus,
“reasonable forecasting and speculation is…implicit in NEPA.” 38 Throughout the process, the
agency cannot simply accept an applicant’s information or conclusions; an agency must verify
the accuracy of information supplied by the applicant. 39
B.

The Corps Must Review The Proposed Project Through A Lens of Environmental
Justice And The Federal Government’s Commitment To Protect Tribal Treaty
Rights.

The Corps must incorporate environmental justice 40 and the federal government’s
commitment to respect tribal knowledge and rights throughout the entire EIS process. Both

There is no one preferred definition for environmental justice. In 1991, the First National People of Color
Environmental Leadership Summit developed a set of environmental justice principles that still guide the
environmental justice movement today. See Environmental Justice Principles.
http://www.columbia.edu/cu/EJ/Reports_Linked_Pages/EJ_principles.pdf. According to the Corps, environmental
justice is “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or
income with respect to the development, implementation, and enforcement of environmental laws, regulations,
and policies, with no group bearing a disproportionate burden of environmental harms and risks.” See

of the potential impacts on “frontline communities,” like tribal communities, which are likely to
be disproportionately impacted by the environmental impacts of the Project. 41
Executive Order 12898, “Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations,” provides that all federal agencies must:
make environmental justice part of [their] mission by identifying and addressing,
as appropriate, disproportionately high and adverse human health and
environmental effects of [their] programs, policies, and activities on minority
populations and low-income populations in the United States. 42
Its provisions apply fully to programs involving tribal nations and members. 43 Executive Order
12898 is intended to require consideration of environmental justice concerns in the NEPA
process. 44 Executive Order 12898 emphasizes “the importance of research, data collection, and
analysis,” particularly with respect to “multiple and cumulative exposures” to environmental
hazards for low-income populations, minority populations, and Indian tribes. 45 Further, it
provides for agencies to collect, maintain, and analyze information on patterns of subsistence
consumption of fish, vegetation, or wildlife. Where an agency action may affect fish, vegetation,
or wildlife, that agency action may also affect subsistence patterns of consumption and indicate
the potential for disproportionately high and adverse human health or environmental effects
on low-income populations, minority populations, and Indian tribes. 46
Accordingly, the scope of the EIS must evaluate the potential for the Project’s
construction or operation to pollute fish, vegetation, and wildlife that are part of the food chain
for tribal members. 47
Recent executive orders reinforce the need to pay special attention to environmental
justice impacts of the Corps’ decision-making processes. Executive Order 14008, “Tackling the
Climate Crisis at Home and Abroad,” directs federal agencies to promote environmental justice
See Standing Rock Sioux Tribe v. U.S. Army Corps of Engineers, 255 F. Supp. 3d 101, 140 (D.D.C. 2017) (holding
that an environmental assessment failed to properly consider the environmental justice implications of a project
where it did not consider the cultural, social, and economic factors that are distinct to the Tribe and that “might
amplify its experience of the environmental effects of an oil spill”).

by “[d]eveloping programs, policies, and activities to address the disproportionately high and
adverse human health, environmental, climate-related and other cumulative impacts on
disadvantaged communities, as well as the accompanying economic challenges of such
impacts.” 48 Executive Order 13990, “Protecting Public Health and the Environment and
Restoring Science to Tackle the Climate Crisis,” recognizes the importance of ensuring access to
clean air and water, limiting exposure to dangerous chemicals and pesticides, and holding
polluters accountable. 49 The Corps should promote environmental justice through enhancing its
public participation processes and evaluating the disproportionate impacts of the Line 5 tunnel
project. As explained by CEQ, “[t]he participation of diverse groups in the scoping process is
necessary for full consideration of the potential environmental impacts of a proposed agency
action and any alternatives.” 50
The Corps’ evaluation of environmental justice impacts of the Project will demonstrate
that constructing a tunnel and routing a pipeline through the Straits of Mackinac will
disproportionately harm Bay Mills and other Tribal Nations. The EIS should consider a full range
of the potential environmental justice impacts including, but not limited to, the following:
•

Threats to tribal fisheries;

•

Impairment of tribal members’ ability to harvest natural resources for food,
medicine, and ceremony along the route of the pipeline;

•

Harm to resources of cultural, economic, and spiritual importance to Bay Mills;

•

Frustration of spiritual activities such as ceremonies in and around the Straits;
and,

•

Social, economic, and health impacts for Bay Mills and other tribal communities.

The Corps must respect the Tribal Nations’ perspective and stake in the Proposed
Project.
C.

The National Historic Preservation Act’s Section 106 Process Must Inform The
EIS Process, Including The Development, Consideration, And Selection Of
Alternatives.

The Corps’ development, selection, and evaluation of project alternatives in the NEPA
process must be informed by the National Historic Preservation Act’s (“NHPA”) Section 106
Exec. Order No. 14008, 86 Fed. Reg. 7619, 7629. Section 220 of Exec. Order 14008 creates an interagency
working group, including HUD and EPA, and calls on the group to address “current and historic environmental
injustice.” Id. at 7630. Note that although Exec. Order 14008 and the implementing memos and materials use the
phrase “disadvantaged communities,” there are more appropriate terms that should be used, and community
members should be consulted on the preferred term.

process; specifically, the Corps must develop and evaluate alternatives that avoid, minimize, or
mitigate adverse effects to historic properties. The Advisory Council on Historic Preservation’s
Section 106 implementing regulations, which are binding on all federal agencies including the
Corps, 51 require the Section 106 process to be “initiated early in the undertaking’s planning, so
that a broad range of alternatives may be considered during the planning process for the
undertaking.” 52 Indeed, in order to resolve any adverse effects to historic properties that may
occur because of the undertaking, the Corps must “develop and evaluate alternatives or
modifications to the undertaking that could avoid, minimize, or mitigate adverse effects on
historic properties.” 53
For the Corps to meet this regulatory requirement, the Section 106 process cannot be
delayed, and the information gained from it must be used in developing, selecting, and
evaluating project alternatives in the parallel NEPA process. If the Corps develops and selects
project alternatives without the consideration of potential adverse effects to historic
properties, the Corps will foreclose its ability to meaningfully consider alternatives and
modifications to the Line 5 tunnel project that could avoid, minimize, or mitigate those adverse
effects. 54 This would be unlawful.
The Corps was presented with a unique opportunity to initiate the Section 106 process
well before the formal EIS process commenced, allowing it to engage in early and meaningful
consultation with consulting parties, including Tribal Nations and Bay Mills. The Corps
announced that it would develop an EIS for the Line 5 tunnel project, instead of an
Te-Moak Tribe of W. Shoshone of Nev. v. U.S. Dep’t of Interior, 608 F.3d 592, 607 (9th Cir. 2010) (“[F]ederal
agencies must comply with these regulations.” (citations omitted)). The Corps purports to comply with Section 106
not by following the procedures set forth in Part 800, but those set forth in 33 C.F.R. Part 325, Appendix C. As Bay
Mills has repeatedly stated, the Corps’ use of Appendix C to fulfill its Section 106 obligations is unlawful, because
Appendix C is not a legally valid counterpart regulation. Sayler Park Vill. Council v. U.S. Army Corps of Eng’rs, No. C1-02-832, 2002 WL 32191511, at *7 (S.D. Ohio Dec. 30, 2002) (“[B]y issuing a permit to Lone Star without having
complied with the regulations issued by the ACHP, the Corps violated the NHPA.”). First, the ACHP never approved
or concurred in the adoption and use of Appendix C. Comm. to Save Cleveland’s Huletts v. U.S. Army Corps of
Eng’rs, 163 F. Supp. 2d 776, 792 (N.D. Ohio 2001) “All parties agree that there is no record of the ACHP ever
approving or concurring in the Corps’ regulations.”). The ACHP’s approval or concurrence was, at the time
Appendix C was developed and adopted, and still is, a requirement for any agency, including the Corps, to develop,
adopt, and use counterpart regulations (or alternate procedures). Accord 36 C.F.R. § 800.14(a); 36 C.F.R. § 800.15
(1986); 36 C.F.R. 800.11(a) (1979). Second, most of the provisions in Appendix C conflict or are inconsistent with
the corresponding provisions in Part 800 and the NHPA. (Cleveland’s Huletts, 163 F.Supp.2d at 792 (“[T]he Corp’s
procedures are inconsistent with, and indeed, in derogation of those ACHP regulations.”). The NHPA specifically
requires agency-specific policies and procedures for implanting Section 106 to be consistent with the ACHP’s
regulations at Part 800. 54 U.S.C. § 306102(b)(5)(A); 36 C.F.R. § 800.14(a).

Environmental Assessment (“EA”), in June 2021. The Corps published its NOI in August 2022.
Over that 14-month period, the Corps suspended the Section 106 process, refusing to engage in
any consultation with consulting parties, including Tribal Nations and Bay Mills. Bay Mills
objected to this suspension and urged the Corps to reinitiate the Section 106 process. 55
Had the Corps not suspended the Section 106 process, or had it reinitiated the process
upon Bay Mills’ request, the Corps could have spent the last 14 months consulting with Bay
Mills, other Tribal Nations, and consulting parties about the historic properties that may be
affected by the undertaking and what the potential adverse effects could be. The information
gained from these consultations could have informed the Corps’ development and selection of
project alternatives in the NEPA process, as is required by the regulations. Instead, the Corps
chose to ignore Tribal Nations and its Section 106 obligations and refused to engage in Section
106 consultation during that 14-month period. Now that the EIS process is underway, the Corps
still has not reinitiated the Section 106 process. This is unacceptable and unlawful. Bay Mills is
deeply concerned that the Corps will not engage in meaningful consultation with consulting
parties early enough so that the Section 106 process can have a meaningful impact on the
permitting process, including the development, selection, and evaluation of project
alternatives, as well as the Corps’ final decision on whether to issue Enbridge a 404 permit.
The Section 106 process is not a post-decision mitigation measure meant to offset the
undertaking’s adverse effects; instead, it is meant to inform agency’s decision making to avoid,
minimize, and mitigate those potential adverse effects in the first place through the
development of project alternatives and modifications. Therefore, it is imperative that the
Corps initiate the Section 106 process early in its permitting process and meaningfully integrate
it with the on-going NEPA process. If the Corps proceeds with developing and selecting project
alternatives in the NEPA process, without input from the Section 106 process, it runs the risk of
being too invested in its analysis of those alternatives to be willing or able to seriously consider
different alternatives and project modifications that could resolve adverse effects to historic
properties. Further, as discussed below, because serious concerns have arisen related to the
Section 106 pre-construction surveys, the entire EIS process should be paused now because the
Corps will not be able to meaningfully consider alternatives or modifications developed with
the benefit of the Section 106 process.
The Corps’ failure to meaningfully consider such alternatives or modifications would be
unlawful.
IV. THE SCOPE OF THE EIS SHOULD ADDRESS THE DEFICIENCIES IN THE APPLICANT’S PERMIT.
Enbridge’s permit application was jointly submitted to the Corps and the Michigan
Department of Environment, Great Lakes, and Energy (“EGLE”) in April of 2020. 56 At the time of

submission, the Corps notified Enbridge that additional information was necessary in order to
continue processing its application. 57 Despite Enbridge’s submission of incomplete application
materials, however, the Corps moved forward with publishing a public notice about the
Proposed Project in May of 2020. 58 Because the public notice was required to “include
sufficient information to give a clear understanding of the nature and magnitude of the activity
to generate meaningful comment,” the Corps was in error for publishing the notice in May of
2020 based on Enbridge’s incomplete application materials. 59
Following public notice, Bay Mills commented that Enbridge’s rushed, chaotic, and
incomplete submission of its permit materials and the ongoing safety problems with its Line 5
pipeline operation did not instill confidence in Enbridge’s ability to proceed with this Project in
a way that protects precious Great Lakes resources. 60 That lack of confidence has only been
amplified as the NEPA process unfolded. To date, Enbridge’s plans remain inadequate,
incomplete, and demonstrate an overall lack of understanding about the complexities of
tunneling through the Straits and little awareness about the effects its Project will have on
Tribal Nations.
An application for a permit must include, among other things, a complete description of
the proposed activity; the location, purpose, and need for the proposed activity; all activities
that the applicant plans to take which are reasonably related to the same project; a description
of any dredging in navigable waters that the activity would entail; a description of the discharge
of any dredged or fill material into the waters of the United States that the activity would
entail, including the source of the material, purpose of the discharge, description of the
material, the method of transportation and disposal, and the location of the disposal site; and a
statement of how impacts to waters of the United States are to be avoided or minimized for
activities involving discharges of dredged or fill materials. 61 A permit application is complete
only “when sufficient information is received to issue a public notice.” 62 Enbridge’s application

was incomplete at the time it was submitted, and remains substantially incomplete today, for
the following reasons:
•

The application lacks an explanation for the need for the Project. 63

•

The application lacks an adequate description of the decommissioning options
for the dual pipelines. 64

•

The application does not address cumulative impacts to the affected
watersheds. 65 Enbridge’s application is silent about the cumulative impacts that
its Project will cause, and Enbridge has failed to adequately address cumulative
impacts in its supplemental materials.

•

The application and supplemental materials fail to include a complete
description of the type, composition, and quantity of the material to be dredged,
the method of dredging, and the site and plans for disposal of the dredged
material.

•

The application and supplemental materials fail to include an adequate
statement describing how impacts to waters of the United States are to be
avoided and minimized, as required by section 325.1(d)(7)(1).

•

The application fails to include any financial assurances, or an adequate
statement that either describes “how impacts to waters of the United States are
to be compensated for” or “explain[s] why compensatory mitigation should not
be required for the proposed impacts.” 66

It is unacceptable that, more than two years after submitting its application, Enbridge’s
application materials and supplemental submissions remain incomplete. At present, Bay Mills
and the public are missing information that they should be able to comment on, and the Corps
is missing out on the benefits of those public comments.
Moreover, an issuance of the permit based on Enbridge’s incomplete application would
run afoul of the “hard look” of the Project that is required by NEPA. 67 Indeed, “[a]ccurate
scientific analysis, expert agency comments, and public scrutiny are essential to implementing

NEPA.” 68 “NEPA procedures must insure that environmental information is available to public
officials and citizens before decisions are made and before actions are taken” and that the
information must be of “high quality.” 69 As part of the EIS process, these deficiencies in the
permit application must be corrected immediately. Once the information is provided by
Enbridge, the Corps should issue a supplemental, revised, or corrected public notice based on
the change in the application data that would affect the public’s review of the proposal. 70
V. THE EIS SHOULD ADDRESS WHETHER THERE IS A NEED FOR THIS PROJECT AND EVALUATE
A WIDE RANGE OF ALTERNATIVES.
In the NOI, the Corps’ statement of purpose and need is so narrow that it seems to leave
room for just one result: the construction of the Project. 71 But “a statement of purpose and
need ‘will fail if it unreasonably narrows the agency’s consideration of alternatives so that the
outcome is preordained.’” 72 The EIS must not be so limited. Consideration of such a narrow
range of alternatives is inconsistent with the Corps’ obligations under the implementing
regulations of Section 106 of the NHPA. The EIS should address whether there is a need for the
Project and consider a full range of alternatives, including alternatives in which there would be
no pipeline crossing the Straits. A tunnel in the straits is not a foregone conclusion.
A.

There Is No Established Need For The Continued Transportation Of Oil And
Propane Products Through The Line 5 Pipeline.

The scope of the EIS should include an evaluation of the purported need for this
Project. 73 Moreover, the Corps should address the needs and welfare of the people and the
relative need for the proposed project before issuing any permit under Section 404 of the Clean

See 40 C.F.R. § 1500.1(b) (1978) (“NEPA procedures must insure that environmental information is available to
public officials and citizens before decisions are made and actions are taken.”)

Other sections of the NOI are also unduly narrow. Both the “Purpose and Need” and the “Location” sections of

Water Act. 74 The published NOI has a one sentence “Purpose and Need” section that is overly
narrow as to the purpose and silent as to the need for the Project:
Purpose and Need: The purpose of the project is to provide transportation of light
crude oil, light synthetic crude oil, light sweet crude oil, and natural gas liquids
between Enbridge’s existing North Straits Facility and Mackinaw Station, and to
approximately maintain the existing capacity of the Line 5 pipeline while
minimizing environmental risks. 75
Limiting the purpose of the project to transportation of fuels “between Enbridge’s existing
North Straits Facility and Mackinaw Station” defines reasonable alternatives out of existence,
which federal agencies are prohibited from doing. 76 This unreasonably narrow geographic
definition of the Project’s purpose must not be used to limit the scope of the EIS.
Similarly, a purpose of “approximately maintain[ing] the existing capacity of the Line 5
pipeline” appears to unreasonably limit the Corps’ review of alternatives and must not be used
to bar the review of reasonable alternatives. Transporting the fuels through other pipelines
with existing capacity or transporting the fuels by truck or rail are all “reasonable alternatives”
that the Corps must review. 77
In fact, before accepting that fuels must be transported—let alone be transported at a
set capacity between specific locations—a need for the fuels must be established. There is no
basis to suggest that the existing capacity of Line 5 is necessary now, let alone in the future.
This is especially true in light of the climate crisis and governmental goals for carbon emissions
reductions. 78
No studies or reports demonstrate that the products transported by the Line 5 pipeline
(especially at its current capacity) are needed in the region. Instead, expert testimony in other
Line 5 proceedings, the historical record, and independent reports demonstrate that there is no
such need:

pipelines to shut down completely for a week and for one of the dual pipelines
to be shut down for 78 days. 79 During that period of time, gas prices in Michigan
and Toronto remained near the United States and Canadian averages for gas
prices. 80
•

Neil Earnest, an expert hired by Enbridge, has concluded that Line 5 has little
impact on fuel prices: “The estimated impact of a Line 5 shutdown on Wisconsin
and Michigan gasoline, jet fuel, and diesel prices is an increase of 0.5 cents per
gallon.” 81

•

The Upper Peninsula Energy Task Force, an entity created by the Michigan
governor, commissioned an economic analysis of propane supply alternatives to
Line 5, and the analysis concluded that any shortfall in propane supply from a
disruption to Line 5 could be overcome through a combination of readily
available alternatives that include delivery of propane by rail, truck, and pipeline
from Edmonton, Alberta, and Conway, Kansas. 82

•

There are practical and economic alternatives to propane, including electric heat
pumps and electric hot water heaters. 83

Energy demands may be satisfied by other methods that may result in fewer
greenhouse gas emissions. It is imperative that any mention of a supposed need for fossil fuels
account for how long those fossil fuels would be transported and burned in the future and the
climate, policy, and environmental justice implications of that usage.
To date, no need for the Project is established, and if no need is established, the Corps
should halt the EIS process and deny the application. At the very least, for public transparency,
the Corps must state a need in the EIS so that an appropriate set of alternatives can be

evaluated, and because evaluating need is a component of the public interest review the Corps
must conduct before issuing a permit, pursuant to Section 404 of the Clean Water Act. 84
B.

The Corps Must Consider Alternatives In Which No Pipeline Would Cross The
Straits.

The EIS must include a robust consideration of alternatives in which there would be no
pipeline in or beneath the Straits of Mackinac.
There are several independent reasons to include “no pipeline in the Straits”
alternatives in the EIS. First, there is no established need for Line 5 to operate. As Section V.A,
supra, explains, there is no economic or energy security need for continuing to use this pipeline,
let alone building and rerouting new segments of it. Alternatives to this Project could include an
electric grid more reliant on renewable energy.
Second, even if there were a need for fossil fuel products that Line 5 transports—which
there is not—there is no reason for these products to travel through the Straits of Mackinac.
The opposite is true: A fossil fuel pipeline has no place in waters of such immense cultural,
spiritual, and economic significance to Bay Mills and other Tribal Nations. Alternatives to this
Project could be reliance on other existing pipelines or the use of truck and rail infrastructure.
Third, the Clean Water Act requires the Corps to presume that there are “practicable
alternatives that do not involve special aquatic sites,” 85 such as the wetlands on either side of
the Straits, 86 to this project because it is not “water dependent.” Transporting fuel through a
pipeline is not water dependent, 87 and Enbridge’s desire to locate the pipeline in the Straits
does not make this project water dependent. 88 The Corps must presume that there is a

can select a different pipeline route or other alternative that does not affect an aquatic site”); Bering Strait Citizens
for Responsible Res. Dev. v. U.S. Army Corps of Eng’rs, 524 F.3d 938, 947 (9th Cir. 2008) (recognizing that a

gold mining requires access or proximity to water); City Club of New York v. U.S. Army Corps of Eng’rs, 246 F. Supp.
3d 860, 870 (S.D.N.Y. 2017) (“A project whose fundamental goal is to provide park and performance space is not
water dependent, regardless of whether the [applicant] prefers to build such space on a pier.”); see also Sierra
Club v. Van Antwerp, 709 F.Supp.2d 1254, 1261 (S.D. Fla. 2009) (noting that dams and marinas are water
dependent) (quoting Army Corps of Engineers Standard Operating Procedures for the Regulatory Program
(October 15, 1999)), aff’d, 362 Fed. App’x 100 (11th Cir. 2010).
88
Similarly, the basic purpose of a limestone mine is mining limestone, regardless of the permit applicant’s
preferred mining location. Sierra Club v. Van Antwerp, 362 F. App’x at 106. In Sierra Club v. Van Antwerp, the court
recognized that the Corps had correctly defined the purpose of a project as the extraction of limestone, but then
acted arbitrarily and capriciously by concluding that the project was water dependent. The court rejected the idea
that, although the extraction of limestone is not always water dependent this particular project was water
dependent because of its location, and vacated the section 404 permit.

practicable alternative to the Project that does not involve the proposed location for the
Project.
Fourth, alternatives where there are no pipelines in the Straits overlap with “No Action”
alternatives that NEPA requires the Corps to consider. 89 “Where a choice of ‘no action’ by the
agency would result in predictable actions by others, this consequence of the ‘no action’
alternative should be included in the analysis.” 90 Uncertainty regarding what would happen in
the absence of an agency action supports the discussion of multiple no action alternatives. 91
The scope of the EIS must account for the various scenarios that would occur in the absence of
agency action here, including those in which no pipeline operates in the Straits because:
•

Enbridge complies with or is forced to comply with the Notice of Revocation and
Termination of the 1953 easement and ceases to operate the dual pipelines in
the Straits; 92

•

A court enjoins the operation of the dual pipelines in the Straits in the ongoing
litigation brought by the Michigan Attorney General; 93

•

Enbridge ceases to operate Line 5 (including the dual pipelines in the Straits)
because it is forced to cease operating a portion of the pipeline in Wisconsin as a
result of ongoing litigation; 94 or,

•

Enbridge ceases to operate the dual pipelines earlier than it would cease to
operate the Project, consistent with its depreciation study for the current
pipeline system (by 2040) as compared to the length of time for which it has
obtained an easement to operate the Project (99 years). 95

Finally, the Advisory Council on Historic Preservation’s Section 106 implementing
regulations require the Corps 96 to consider “a broad range of alternatives.” 97 In order to resolve
any adverse effects to historic properties that may occur because of the undertaking, the Corps
must “develop and evaluate alternatives and modifications to the undertaking that could avoid,
minimize, or mitigate adverse effects on historic properties.” 98 Naturally, to avoid, minimize, or
mitigate adverse effects, alternatives that do not involve a pipeline in the Straits must be
considered given that the Straits are a Traditional Cultural Property and home to many historic
properties. 99
C.

The Tunnel Agreements Between The State Of Michigan And Enbridge Do Not
Determine Or Limit The Scope Of The EIS, Location, Or Project Alternatives.

The NOI acknowledges a Tunnel Agreement executed by Enbridge and the State of
Michigan and Public Act 359; 100 however, neither the Tunnel Agreements nor Act 359
circumvent the EIS process or any other permitting process. Instead, both the Tunnel
Agreement and Act 359 demand that the permitting processes be carried out, anticipating and
supporting a full EIS. Subject to the consent and approvals of federal and state agencies, 101 Act
359 “creates the Corridor Authority and . . . authorizes the Corridor Authority to operate the
utility tunnel.” 102 The Tunnel Agreement dated December 19, 2018 followed Act 359 and
recognized that there were “required” governmental permits or approvals that would precede
any construction or use in furtherance of a tunnel. 103 In conditioning the construction of a
utility tunnel on agency approvals, Act 359 and Tunnel Agreements not only contemplate the
possibility that the tunnel would not be approved, but they do not limit the reviews that
permitting agencies like the Corps must conduct. The Corps should not artificially limit the
alternatives to the project based on Act 359 or the Tunnel Agreements.
VI. THE SCOPE OF THE EIS MUST INCLUDE RELATED ACTIONS ON THE LINE 5 PIPELINE.
The scope of the EIS must account for the relationship between this Project and other
connected, cumulative, and similar actions, including: (1) other actions along Line 5 that require
federal approval, including the Line 5 Segment Relocation Project that is being considered by
“[F]ederal agencies must comply with these regulations,” and the Corps is a federal agency. Te-Moak Tribe of W.

special use permits currently and/or imminently pending before the U.S. National Forest 105; (2)
the decommissioning of the dual pipelines; and (3) planned and future projects to repair,
reroute, and maintain Line 5 to keep oil flowing to and from this Project. To look only at the
Straits would effectively ignore the impacts of this Project.
NEPA’s implementing regulations direct federal agencies to consider three types of
actions in order to determine the scope of an EIS: connected actions, cumulative actions, and
similar actions. 106 The tunnel, reroute, and U.S. National Forest projects of Line 5, as well as the
decommissioning of the dual pipelines and repairs to Line 5, are all connected, cumulative, and
similar actions, and thus the Corps should address the environmental effects of all of these
actions in the EIS for the Project. 107 There is sufficient federal “control” over other parts of the
project (through permit approvals) that the cumulative federal involvement calls for this
inclusive scope. 108
Connected actions are “closely related and therefore should be discussed in the same
impact statement.” 109 Actions are connected if they: “[a]utomatically trigger other actions
which may require environmental impact statements”; “[c]annot or will not proceed unless
other actions are taken previously or simultaneously”; or “[a]re interdependent parts of a larger
action and depend on the larger action for their justification.” 110 Projects are “connected”
where they lack independent utility. Further, where projects are concurrently pending before

Forests. For example, in 1980, oil leaked from Line 5 in the Hiawatha National Forest, and “contaminated soil and
groundwater persisted at the site for more than three decades.” See Keith Matheny, 30 years later, contamination

an agency, proposed by the same company, and logically interdependent, they may be
connected. 111
Cumulative actions are actions “which when viewed with other proposed actions have
cumulatively significant impacts and should therefore be discussed in the same impact
statement.” 112 Where multiple proposed actions are pending before an agency at once, the
agency should consider the cumulative and collective impacts of those actions. 113 A meaningful
cumulative impact analysis must identify: “(1) the area in which the effects of the proposed
project will be felt; (2) the impacts that are expected in that area from the proposed project; (3)
other actions—past, present, and proposed, and reasonably foreseeable—that have had or are
expected to have impacts in the same area; (4) the impacts or expected impacts from these
other actions; and (5) the overall impact that can be expected if the individual impacts are
allowed to accumulate.” 114
Similar actions are actions “which when viewed with other reasonably foreseeable or
proposed agency actions, have similarities that provide a basis for evaluating their
environmental consequences together, such as common timing or geography.” 115
A.

The EIS Must Consider The Environmental Impacts Of Other Segments Of Line 5
Requiring Permits.

The Project is dependent on the approval of the proposed Relocation Project and the
reauthorization of multiple Forest Service special use permits. The Relocation Project and
National Forest segments are necessary to supply the fuels to be transported by the Proposed
Project. 116 Oil from Alberta, Canada will not be able to reach its destination in Sarnia, Ontario
via the Project without the oil flowing through the segments of Line 5 traversing around the
Bad River Reservation and through the pipeline as it crosses the Chequamegon-Nicolet National
Forest, the Ottawa National Forest, and the Hiawatha National Forest. If any one of these
projects is not permitted, the product will not reach the Straits and there will be no purpose for
the tunnel project. Each segment of the pipeline cannot proceed without the other. The

applicant’s representatives or agency personnel] the existence of reasonably certain alternative petroleum supply
sources . . . or other circumstances indicating with reasonable clarity that the Williams pipeline will not rely on the

Relocation Project, special use permits, and this Project are interdependent parts of the entire
Line 5 and depend on each other and the continued operation of Line 5 for their justification.
Moreover, these projects are proposed by the same company, at approximately the
same time, along the same pipeline, and all within the ecological area of the Great Lakes
Basin. 117 When viewed together, the Project, the Relocation Project, and the reauthorization of
the Forest Service special use permits are actions have reasonably foreseeable and cumulatively
significant impacts, and thus the impacts of each action must be included in this EIS. Therefore,
each of these actions should be discussed in this EIS.
B.

The EIS Must Consider the Environmental Impacts Of Decommissioning The
Line 5 Dual Pipelines, Including Alternative Methods Of Decommissioning.

Enbridge has characterized decommissioning as “the only activity that is certain to occur
once the Project has been constructed.” 118 Decommissioning of the existing Line 5 dual
pipelines is an integral part of the Project, and the environmental impacts of each of the
decommissioning alternatives must be considered in the EIS. 119 However, Enbridge has also
changed its plans for decommissioning—and Enbridge’s changing plans cannot be a basis for
improperly segmenting decommissioning from the Project. 120 The scope of the EIS must
address all impacts of each possible decommissioning alternative.
At the inception of the Line 5 Tunnel Project plan, Enbridge, the Corps, and the State of
Michigan acknowledged in writing on multiple occasions the need for compliance with federal
and state regulations and well as the need to study two options for decommissioning: removal
of or abandonment of the pipelines in place.
Enbridge’s April 8, 2020 Joint Permit Application includes decommissioning of the
existing pipelines, stating that “[o]nce the new segment of the pipeline across the Straits is put
into service, the existing dual pipelines will be decommissioned in accordance with federal,
state, and local regulations . . .” 121 On April 14, 2020, recognizing the inadequacy of this
description, the Corps sought substantial additional information about the Project including

company were not independent).

“deactivating them in place.” Id. As noted in the response, the proposal to decommission in place has not been
approved by the State of Michigan. Id.

details of the decommissioning, and indicated that Enbridge’s permit application would not be
deemed complete unless the information was submitted. 122
On May 4, 2020, in response to the Corps’ information request, Enbridge provided two
options for decommissioning the pipelines. 123 The first option was “Abandonment in Place of
Dual Pipelines:” Enbridge would leave all 21,000 feet of each pipeline in place and would purge
and clean the pipelines and plug/grout the ends. 124 The second option was “Removal of
Unburied/Exposed Sections of the Dual Pipelines:” Enbridge would remove those portions of
the pipelines that are fully or partially exposed and not fully buried along the shoreline. The
removal option would entail: (1) purging/cleaning the pipelines; (2) removing all screw anchor
supports or cutting them near the mudline; (3) “jet sledding” the partially covered portions of
the pipelines and anchor supports to remove sediment to allow for cutting and removal; (4)
cutting the pipelines into segments; (5) capping the ends of the remaining, buried portions of
the pipelines; (6) winching the pipelines segments of pipe that are closer to the shoreline of the
Straits and cutting them into lengths suitable for transportation; (7) cleaning and transporting
the pipeline segments off-site; and (8) monitoring the remaining sections of the pipelines. 125
The Corps’ May 15, 2020 Public Notice included these two decommissioning options. 126
Throughout the Michigan permitting process for the Project, EGLE inquired about
Enbridge’s plans to decommission the dual pipelines; in response to one of EGLE’s inquiries,
Enbridge acknowledged that decommissioning may involve disturbance to the bottomlands,
require an NPDES permit, and cause other environmental impacts. 127

would be cleaned, and exposed portions of the pipeline between the 65-foot depth contours would be removed.”)
(emphasis added). The Tunnel Agreements between the State of Michigan and Enbridge also contemplate that the
two alternatives for decommissioning will be considered by regulatory agencies and will require regulatory
approvals. Second Agreement Between the State of Michigan, Michigan Department of Environmental Quality, and

However, in March 2021, without explanation or support, Enbridge began asserting that
it would decommission in place without consideration of the alternatives or environmental
impacts. 128 The NOI repeats Enbridge’s plans to decommission in place upon completion of the
tunnel construction: “Upon completion, Enbridge proposes to decommission the existing
submerged Line 5 dual pipelines crossing the Straits by purging, cleaning, and abandoning them
in place.” 129 The NOI does not indicate that the EIS will consider the impacts of both
decommissioning in place and removal of the pipelines; the Corps should not accept Enbridge’s
unilateral selection of one decommissioning option without undertaking the proper analysis
required under NEPA.
The direct, indirect, and cumulative impacts of decommissioning must be assessed.
These effects include impacts to cultural and archeological resources, threatened and
endangered species, critical spawning grounds, environmental impacts, and public trust
considerations. 130 As the Corps and SHPO have acknowledged, the Straits are a Traditional
Cultural Property, which means that the removal of the extant lines might disturb the
bottomlands and disrupt the integrity of the Traditional Cultural Property. Even under the
narrowest decommissioning option—leaving the pipelines in place—there are potential effects;
given the pipelines’ elevated position in many sections, the danger of anchor strikes remains,
risking disturbing the retired lines and impacting surrounding bottomland resources. Corrosion
of the abandon lines could harm surrounding aquatic environments. 131 Maintenance of the
remaining pipelines threatens critical elements of the Traditional Cultural Property because the
maintenance equipment and activities could disturb cultural resources.
The decommissioning options should not be segmented from the rest of the Project or
ignored.
C.

The EIS Must Consider The Environmental Effects Of Repairs To Line 5.

The direct, indirect, and cumulative environmental effects of this Project include the
effects of likely future projects to repair, reroute, or maintain Line 5 to keep the Project
operating as a pipeline through and on either side of the Straits. In other words, this Project is a
foot-in-the-door for other projects along Line 5. First, the Project will require repairs to the
proposed tunnel or pipeline in the tunnel, including the possibility of flammable or explosive
product escaping during a repair. Second, the Project will entail repairs to the facilities and
pipeline on the north and south sides of the Straits, especially in light of potential erosion along
the lakes. Third, foreseeable effects of the Project include repairs to the pipeline traveling to
and from tunnel to other segments where products are added to the pipeline or taken off of
the pipeline, including the possibility that repairs will cause the clearing of wetlands or other
habitats, trenching through waterways, or other land- or water-based environmental impacts.

The impacts of all of these projects add up. To that end, the EIS should include information on
how long a pipeline built in 1953 is expected to safely function.
It is reasonably foreseeable that such repairs will occur, and they must be within the
scope of the EIS.
VII. THE EIS MUST INCLUDE THE LIKELIHOOD AND ENVIRONMENTAL IMPACTS OF AN OIL SPILL
IN THE GREAT LAKES BASIN.
The Proposed Project is one of the key determinants of whether and how long into the
future Line 5 will continue to operate. The environmental effects of the Proposed Project thus
include the direct, indirect, and cumulative impacts of Line 5—namely, the risk that oil spills
into the environment. 132 Accordingly, the impacts of an oil spill from Line 5 into any of the
interconnected waters of the Great Lakes Basin must be part of the scope of the EIS. A tunnel,
or any other purported solution to the risk of the dual pipelines spilling in the Straits, is not
foolproof and does not reduce the likelihood of an oil spill elsewhere along the pipeline. 133 Oil
pipelines spill, damaging the environment. In the Great Lakes Basin, where the waters are
interconnected, a spill from Line 5 in one waterway will travel through the waters, thus
threatening a larger area.
The Corps cannot narrow its focus to the Straits crossing or Mackinac and Emmet
Counties – as the NOI appears to – because the Project implicates a much larger area. 134 An EIS
cannot set artificial boundaries on hydrologically connected resources or on ecosystems. 135
A.

Pipelines Spill.

It is not a matter of if a pipeline will spill oil, but a matter of when. Data from the
Pipeline and Hazardous Materials Safety Administration (“PHMSA”), reveals that pipeline spills
or leaks occur approximately every other day in the U.S. From 2004 to 2017, PHMSA data
showed there were an average of 186 incidents involving crude oil pipeline systems in the

See Delaware Riverkeeper Network v. FERC, 753 F.3d 1304 (D.C. Cir. 2014) (requiring meaningful analysis of
cumulative impacts); Grand Canyon Trust v. FAA, 290 F.3d 339, 345 (D.C. Cir. 2002) (same); Indigenous Envt’l
Network v. United States Dep’t of State, 347 F. Supp. 3d 561, 582, 590 (D. Mont. 2018) (requiring an agency to
address oil spills more fully, including with information about new spills and new studies and by conducting
additional modeling).
133
To the contrary, this Project likely would increase the risk of a spill by extending the lifespan of the pipeline.
134
See Save Our Sonoran, Inc. v. Flowers, 408 F.3d 1113, 1122 (9th Cir. 2005) (“[W]hile it is the development's
impact on jurisdictional waters that determines the scope of the Corps' permitting authority, it is the impact of the
permit on the environment at large that determines the Corps’ NEPA responsibility. The Corps’ responsibility under
NEPA to consider the environmental consequences of a permit extends even to environmental effects with no
impact on jurisdictional waters at all.”).

United States each year, averaging 42,517 barrels of crude oil released per year. 136 Twenty-nine
percent of that oil was never recovered from the environment. 137
Enbridge’s record for oil spills highlights the need for the EIS to study and analyze spill
scenarios. From 1999 to 2010, Enbridge pipelines spilled nearly 7 million gallons of crude oil in
over 800 different incidents across the United States and Canada. 138 The combined
environmental effect of these incidents to wetlands, surface and ground waters has not been
quantified. The most notorious spill involves Enbridge’s ruptured 6B pipeline which spilled over
a million gallons of heavy crude oil into the Kalamazoo River in the lower peninsula of Michigan
in 2010. Cleanup activities at this site are ongoing and the total cost to the environment
currently exceeds $1.2 billion, including clean-up costs, remediation, and fines levied against
Enbridge. 139 One of the largest inland crude oil spills in the United States occurred at Enbridge
Line 3 pipeline near Grand Rapids, Minnesota where approximately 1.7 million gallons of crude
oil were spilled, much of it into the Prairie River, only 2 miles from reaching the Mississippi
River. 140 Line 5 itself has spilled approximately 1 million gallons of oil in approximately 30
separate incidents; see Figure 2. For example, a spill in the Hiawatha National Forest that
occurred around 1980 was never properly cleaned up by Enbridge. 141 Elevated levels of
petrochemicals were detected by field surveys in 2011 in the soil and in groundwater, and the

Minnesota, 80-100 gallons of drilling fluid were released into the Willow River, and the Minnesota Pollution

U.S. Forest Service has no record that Enbridge notified them of this release before 2012. 142 A
significant oil spill is a probable negative effect of the proposed project, with many negative
direct, indirect, and cumulative impacts to be considered in the EIS.

B.

Oil Spills Harm Fish, Birds, Plants, And Other Organisms.

Oil is toxic to aquatic and terrestrial organisms. Freshwater fish, an important piece of
this ecosystem and a major source of income for subsistence fishers, are seriously affected by
oil releases. Fish can be affected through a variety of pathways across life stages. Effects of oil
spills on fish include fish mortality, a decline in abundance and diversity of fish, and fish
consumption advisories affecting the ability of community members to fish for consumption. 143
While dead fish may be observed immediately after the spill, sublethal effects have been
observed two months following a spill, while increases in fish deformities have been observed
two years after a spill. 144

Birds that spend time near or in waterbodies, such as Canada geese, mallard ducks, and
great blue herons, are also highly susceptible to the impacts of oil spills. 145 For example, the
Marshall, Michigan spill led to the death of 52 birds, and necessitated rehabilitation for 144
birds affected by released oil. 146 Oil spills may also require birds to be relocated from the area,
in addition to the resources needed to clean and release birds safely into the environment.
Amphibious and terrestrial animals are also affected by oil spills. Oil-coated skin or
scales in amphibians and reptiles can lead to absorption of toxins, and potentially
suffocation. 147 Spills in warmer times of the year are particularly dangerous to reptiles and
amphibians. The Marshall, Michigan spill resulted in over 100 dead reptiles, and thousands of
turtles requiring capture and treatment for oil effects. 148 Mammals that are adapted to living
near water (semi-aquatic mammals) are also prone to impacts from oil spills. The Marshall,
Michigan spill killed 40 mammals, primarily affecting muskrats, raccoons, and beavers. 149
These effects extend to benthic organisms, microorganisms, and plant life. 150 The effect
on microorganisms can lead to permanent impacts on the quality of the soil, requiring soil
tilling, burning, fertilizer, or bioremediation techniques to return the soil to its original quality,
but these processes require long periods of time. 151 Upon plant exposure to oil, deciduous
plants may show effects within hours, and recovery and regrowth are impeded for many years
into the future. 152
C.

Spilled Oil Moves Through Connected Waters.

The waters of the Great Lakes Basin are connected. A spill from the Project, including
where the pipeline will be routed in and out of the tunnel on the sides of the Straits, would
reach beyond the area of the Straits that the NOI suggests the EIS would be limited to. That
would cause devastating effects to tribal, commercial, and recreational fishing, as well as long
term damage to tourism in the area, ecosystems in the lakes and along the shorelines, and the
many species that live in or migrate through that habitat.

regrowth was considerably less robust in oil-exposed plants, while plants in oil-saturated soil did not regrow. After

Line 5 is located within the Great Lakes watershed and there are areas where oil spilled
from this pipeline could flow into Lake Superior, Lake Michigan, and/or Lake Huron through
tributaries that have no flow interruptions such as lakes or dams; see Figures 3 and 4. Thus, any
spill from Line 5 is a spill of product that would not be in the pipeline or spilled from it without
this Project. Because of the interconnectedness of Great Lakes Basin waters, a spill from one
part of Line 5 can reach waterways throughout the Basin.

D.

This Project Threatens The Ceded Territory With An Oil Spill By Causing Line 5
To Continue Operating Into The Future.

Permitting this Project would have enormous costs in the form of allowing the Line 5
pipeline to operate and/or extending the lifetime of the Line 5 pipeline. Without a pipeline
segment in the Straits, it is unlikely that oil would flow through any other part of Line 5. There
are 454 miles of the Line 5 pipeline in the Ceded Territories under the 1836, 1837, 1842, and
1854 Treaties. Based on GLIFWC’s analysis of reasonable hazard zones, 153 within the Ceded
Territories, Line 5 places at risk of oiling and explosion impacts:
•

275,002 acres of land,

•

450 or more inland lakes,

•

2,254.2 river miles,

•

101,892 acres of wetlands. 154

Accordingly, a cumulative impacts analysis must include all potential impacts where the
pipeline travels, including the lands and waters downgradient of the pipeline. An appropriately
scoped EIS will include a detailed fate and transport model that illustrates the potential spatial
extent of downgradient impacts of a failure of Line 5 in the Great Lakes basin. This information
is necessary to evaluate the risk of spilled oil reaching the Great Lakes, as well as the impacts of
spilled oil on other lands and waters in the Ceded Territory, on public lands (e.g., state forests),
drinking water sources, plants, and animals that tribal members harvest, etc. The modeling
must include a variety of scenarios, including a range of small incidents to catastrophic failures
on the pipeline. The modeling must include different temporal scenarios and it should account
for seasonal variation in conditions such as ice cover, which may hinder spill response time, and
spring floods, which may move the oil across the ecosystem more quickly. Different climatic
scenarios should account for the likelihood of climate change exacerbating oil spill risks by
increasing extreme weather events and contributing to erosion around the pipeline, among
other things.
Additionally, the EIS should include information on how Enbridge would respond to oil
spills in each of those scenarios, including whether Enbridge has the ability to pay for an oil spill
clean-up and response. 155 Enbridge’s ability to pay for a clean-up remains an open question.
Although the Third Tunnel Agreement between the State of Michigan and various Enbridge

entities called for the maintenance of liability insurance until the dual pipelines are
decommissioned, Enbridge entities involved in the proposed project either did not exist at the
time or did not exist in their present form. 156 Cleanup and remediation of an oil spill requires a
lot of time and money. The EIS should describe, in detail, the types of financial assurance that
Enbridge has or can be required to provide to ensure that the public is not burdened with
cleanup and remediation costs.
VIII.

THE EIS MUST ADDRESS CLIMATE CHANGE.
A.

The EIS Must Account For How The Proposed Project Will Cause Greenhouse
Gas Emissions.

The EIS must evaluate the greenhouse gas (“GHG”) emissions and climate change
impacts of the Proposed Project and alternatives. The NOI is correct to include “climate change,
including greenhouse gas emissions and the social cost of greenhouse gases” in the list of
relevant issues. 157 The Proposed Project is a fossil fuel pipeline that would, for nearly a century,
transport fuels that emit GHGs when burned. GHG emissions wreak havoc on the climate,
changing temperature and precipitation patterns and devastating natural resources that are
culturally, spiritually, and economically important to tribal communities like Bay Mills.
Moreover, holdings from federal courts regarding NEPA review and this administration’s orders
and guidance demand that the Corps take a hard look at the Proposed Project’s GHG emissions
and do all it can to reduce GHG emissions. An EIS that properly accounts for the GHG emissions
of this Proposed Project will conclude that the project would have dramatic environmental
impacts and is inconsistent with this Administration’s and the Corps’ climate plans and
guidance.
1.

Legal requirements in the statute, case law, and Executive Orders

GHG emissions and their climate impacts are a proper subject of NEPA analysis—and a
necessary subject of environmental effects and cumulative impacts analyses when an agency
considers permitting a pipeline. NEPA requires agencies to take a “hard look” at the
environmental effects of their actions. Agencies must use the best scientific information
available in their NEPA analyses, including information about climate change. 158 Climate

change, and the GHG emissions that cause it, are a necessary subject of direct, indirect, and
cumulative effects analyses when an agency considers permitting a pipeline. 159
Moreover, federal administrative orders and guidance call on federal agencies to reduce
GHG emissions and factor climate pollution and impacts into decision making. Executive Order
13990 recognizes the threat of climate change and provides that it is the policy of the
Administration “to reduce greenhouse gas emissions” and “bolster resilience to the impacts of
climate change.” 160 The Executive Order 13990 further “directs all executive departments and
agencies (agencies) . . . to immediately commence work to confront the climate crisis.” 161
Executive Order 14008 recognizes that climate change considerations are central to
United States national security and foreign policy, that there must be a “Government-wide
approach that reduces climate pollution in every sector of the economy,” and that the federal
government must take a coordinated approach with state, local, and tribal governments. 162 Per
Executive Order 14008, the Corps prepared a Climate Action Plan, which calls for preparing
responses to climate change and reducing the nation’s vulnerability to climate change. 163
Additionally, the Memorandum of Understanding Regarding Interagency Coordination
and Collaboration for the Protection of Tribal Treaty Rights and Reserved Rights (“MOU”)
requires the Corps to consider and account for the effects of its actions (such as permitting an
oil pipeline) on habitats that support treaty-protected rights and resources (such as the 1836
Treaty Territory), including via climate change. 164
The inclusion of climate change in the EIS is especially important to Bay Mills because
climate change disproportionately impacts Tribal communities. An analysis of climate impacts
of this project should include the GHG emissions from project construction, as well as from the
fuels to be transported by the project. Climate change impacts plants and animals that are
significant in tribal cultures, ceremonies, medicines, diets, and economies. Climate change also
creates more extreme weather events including flash floods which impact rural, low-laying

GHG emissions calculation

The EIS should incorporate Peter A. Erickson’s GHG emissions calculation for the
Proposed Project. Mr. Erickson quantified the GHG emissions from the Proposed Project in
testimony publicly filed with the Michigan Public Service Commission. 165 Mr. Erickson is a
Senior Scientist and the Climate Policy Program Director at Stockholm Environment Institute
U.S., a 501(c)(3) organization affiliated with Tufts University. 166 He has done numerous GHG
emissions calculations, 167 and courts have often relied on and favorably cited his methodology
