Keystone XL Pipeline Project: Key Issues

Summary
In May 2012, Canadian pipeline company TransCanada reapplied to the U.S. Department of State
for a Presidential Permit to build the Keystone XL pipeline. The pipeline would transport crude
oil from the oil sands region of Alberta, Canada, to the existing Keystone Pipeline System in
Nebraska. It also could accept U.S. crude from the Bakken oil fields in Montana and North
Dakota. A second segment of the Keystone XL pipeline system, the Gulf Coast Project, is
proceeding separately to connect existing pipeline facilities in Oklahoma to refineries in Texas.
When completed, the entire Keystone XL pipeline system would ultimately have capacity to
transport 830,000 barrels of crude oil per day to U.S. market hubs. TransCanada submitted the
May 2012 permit application after its 2008 Keystone XL permit application was denied.
The State Department has jurisdiction over the Keystone XL pipeline’s approval because it would
cross the U.S. border. Before it can approve such a permit, the department must determine that the
project is in the “national interest,” accounting for potential effects on the environment, economy,
energy security, and foreign policy, among other factors. Environmental impacts are considered
under the National Environmental Policy Act, as documented in an Environmental Impact
Statement (EIS). For the 2008 permit application, a final EIS was issued in August 2011, followed
by a public review period. Largely in response to public comments and efforts by the state of
Nebraska, the State Department determined that it needed to examine alternative pipeline routes
that would avoid the environmentally sensitive Sand Hills region of Nebraska, a sand dune
formation with highly porous soil and shallow groundwater that recharges the Ogallala aquifer.
The Temporary Payroll Tax Cut Continuation Act of 2011 (P.L. 112-78) required the Secretary of
State to approve or deny the original 2008 project application within 60 days. On January 18,
2012, citing insufficient time under this deadline to properly assess the reconfigured project, the
State Department denied the Keystone XL permit. Since then, TransCanada has worked with
Nebraska officials to identify a pipeline route avoiding the Sand Hills. Its May 2012 permit
application reflects that effort. The State Department has begun the NEPA process anew, but will
largely supplement the August 2011 final EIS to include analysis of the new route in Nebraska, as
well as analysis of any significant environmental issues or information that has become available
since August 2011. The department estimates that it will determine whether to approve or deny
the new Presidential Permit by early 2013.
Since the State Department’s denial of TransCanada’s original permit application, Congress has
debated legislative options addressing the Keystone XL pipeline. The North American Energy
Access Act (H.R. 3548) would transfer permitting authority for the Keystone XL pipeline project
to the Federal Energy Regulatory Commission, requiring issuance of a permit within 30 days of
enactment. Several other bills (H.R. 3811, H.R. 4000, H.R. 4301, S. 2041, and S. 2199) would
immediately approve the 2008 permit application filed by TransCanada, allowing for later
alteration of the pipeline route in Nebraska. A House bill (H.R. 6164), the Domestic Energy and
Jobs Act (S. 3445), and S.Amdt. 2789 would eliminate the Presidential Permit requirement for the
reconfigured Keystone XL pipeline as proposed in TransCanada’s permit application filed on
May 4, 2012. S. 2100 and H.R. 4211 would suspend sales of petroleum products from the
Strategic Petroleum Reserve until issuance of a Presidential Permit for the Keystone XL project.
Although some in Congress have asserted congressional authority over Keystone XL, changing
the State Department’s role in issuing cross-border infrastructure permits may raise questions
about the President’s executive authority. H.R. 3900 would seek to ensure that crude oil
transported by the Keystone XL pipeline, or resulting refined petroleum products, would be sold
only into U.S. markets, but this bill could raise issues related to international trade agreements.

Keystone XL Pipeline Project: Key Issues

Introduction1
In September 2008, TransCanada (a Canadian company) applied to the U.S. Department of State
for a permit to cross the U.S.-Canada international border with the Keystone XL pipeline project.
As originally proposed, the pipeline would carry crude oil produced from the oil sands region of
Alberta, Canada, to U.S. Gulf Coast refineries. Because the pipeline would connect the United
States with a foreign country, it requires a Presidential Permit issued by the State Department.
Issuance of a Presidential Permit requires a finding that the project is in the “national interest.”
Over the course of gathering information necessary to make its national interest determination,
the State Department sought comments from the public as well as local, state, tribal, and federal
agencies. The department received comments on a wide range of issues, including beneficial and
adverse impacts of the proposed project on jobs, pipeline safety, and the environment. According
to the State Department, one of the most common issues raised related to the pipeline’s proposed
route through the Sand Hills region of Nebraska. Also according to the State Department, concern
over the proposed route’s impact on the Sand Hills region had increased significantly over time.
In response to those concerns, as well as action taken by Nebraska’s Governor and legislature, on
November 10, 2011, the department announced that it needed to undertake an in-depth
assessment of alternative pipeline routes that would avoid the Sand Hills.2 That assessment would
be necessary before it could complete its National Interest Determination for the Presidential
Permit. Subsequently, on November 14, 2011, TransCanada announced an agreement with the
Nebraska Department of Environmental Quality to identify a pipeline route that would avoid the
Sand Hills. The State Department estimated at the time that the preparation of supplemental
environmental analysis necessary for a new route alternative could be complete in early 2013.
After the State Department’s announcement of a delay in the permit review, Congress acted to
expedite a permit decision on the Keystone XL project. The Temporary Payroll Tax Cut
Continuation Act of 2011 (P.L. 112-78), enacted on December 23, 2011, included provisions
requiring the Secretary of State to issue a permit for the project within 60 days, unless the
President publicly determined the project not to be in the national interest. The act allowed for
future changes to the Nebraska route if approved by the governor of Nebraska. On January 18,
2012, the State Department, with the President’s consent, denied the Keystone XL permit, citing
insufficient time under the 60-day deadline to obtain all the necessary information to assess the
reconfigured project.3
On February 27, 2012, TransCanada announced that it would proceed with development of the
Gulf Coast Project, a pipeline segment connecting Cushing, OK, to the Gulf Coast refineries,

Keystone XL Pipeline Project: Key Issues

originally proposed as part of the Keystone XL pipeline system subject to a Presidential Permit.4
Its construction and operation may proceed in accordance with applicable regulatory
requirements. However, as a pipeline located entirely within the United States, it does not require
a Presidential Permit from the Department of State. The Obama Administration has stated its
support for the Gulf Coast project, while reserving judgment on the reconfigured northern
segment of the Keystone XL project until completion of a new Presidential Permit review.5 On
May 4, 2012, the State Department received a new application from TransCanada for a
reconfigured Keystone XL pipeline that would run from the Canadian border to connect to an
existing pipeline in Steele City, NE.6 The new application identified proposed new routes through
Nebraska. On September 5, 2012, TransCanada submitted to the Nebraska Department of
Environmental Quality its preferred alternative route for the Keystone XL Pipeline in Nebraska.7
Some Members of Congress have expressed support for the Keystone XL pipeline’s potential
energy security and economic benefits, while others have expressed reservations about its
potential environmental impacts.8 Though Congress, to date, has had no direct role in permitting
the pipeline’s construction, it may have an oversight role stemming from federal environmental
statutes that govern the pipeline’s application review process. Congress also may seek to
influence the State Department permitting process, or may seek to assert direct congressional
authority over permit approval, through new legislation.
A number of legislative proposals, like P.L. 112-78, would have imposed deadlines on a national
interest determination for the Keystone XL project. The North American-Made Energy Security
Act (H.R. 1938) would have directed the President to issue a final order granting or denying the
Presidential Permit for the Keystone XL pipeline by November 1, 2011. The Jobs Through
Growth Act (H.R. 3400) would have required the President to issue a final order granting or
denying the Presidential Permit for the Keystone XL pipeline within 30 days of enactment. The
North American Energy Security Act (S. 1932), which was introduced on November 30, 2011,
would have required the Secretary of State to issue a permit for the project within 60 days of
enactment, unless the President publicly determined the project to be not in the national interest.
The North American Energy Security Act (H.R. 3537), introduced on December 1, 2011, and the
Middle Class Tax Relief and Job Creation Act of 2011 (H.R. 3630), introduced on December 9,
2011, contain similar provisions for issuing a Presidential Permit within 60 days of enactment. All
of these proposed provisions were mooted by the State Department’s initial denial of the permit.

Keystone XL Pipeline Project: Key Issues

The North American Energy Access Act (H.R. 3548), introduced on December 2, 2011, would
transfer the permitting authority over the Keystone XL pipeline project from the State Department
to the Federal Energy Regulatory Commission (FERC), requiring the commission to issue a
permit for the project within 30 days of enactment. The Keystone For a Secure Tomorrow Act
(H.R. 3811), introduced on January 24, 2012, would immediately approve the original permit
application filed by TransCanada in 2008. The Grow America Act of 2012 (S. 2199), introduced
on March 15, 2012; the EXPAND Act (H.R. 4301), introduced on March 29, 2012; S. 2041 (a bill
to approve the Keystone XL pipeline), introduced on January 30, 2012; and the Energizing
America through Employment Act (H.R. 4000), introduced on February 9, 2012, would similarly
approve the original permit upon passage. All six bills include provisions allowing for later
alteration of the pipeline route in Nebraska. A House bill (H.R. 6164), introduced on July 23,
2012, and The Domestic Energy and Jobs Act (S. 3445), introduced on July 26, 2012, would both
eliminate the Presidential Permit requirement for the reconfigured Keystone XL pipeline as
proposed in TransCanada’s permit application filed on May 4, 2012. A Senate amendment
(S.Amdt. 2789) introduced on September 13, 2012, contains the same language.9
H.R. 3900, introduced on February 3, 2012, would seek to ensure that any crude oil transported
by the Keystone XL pipeline, or resulting refined petroleum products, would be sold only into
U.S. markets—not exported overseas. S. 2100, introduced on February 13, 2012, and H.R. 4211,
introduced on March 19, 2012, would suspend sales of petroleum products from the Strategic
Petroleum Reserve until issuance of a Presidential Permit for the Keystone XL project application
filed in 2008.
This report describes the Keystone XL pipeline project, as proposed by TransCanada in its May 4,
2012, Presidential Permit application, and the process and procedures that the State Department is
obligated to complete in processing that permit application. It also summarizes issues that arose
during the 2008 permit application process, particularly those that may affect the current permit
application. This report also summarizes key arguments that have been raised, both for and
against the pipeline, by the pipeline’s developers, state and federal agencies, environmental
groups, and other stakeholders. Finally, the report reviews the constitutional basis for the State
Department’s authority to issue a Presidential Permit, and opponents’ possible challenges to this
authority.
Description of the Keystone Pipeline System
In 2005, TransCanada announced its plan to address expected increases in Western Canadian
Sedimentary Basin (WCSB) production by constructing the Keystone Pipeline System. When
complete, the system would transport crude oil from Hardisty, Alberta, to U.S markets in the
Midwest and Gulf Coast.
The pipeline system was proposed as two segments, the Keystone (complete and in service) and
Keystone XL. The Keystone was completed in two phases—the Keystone Mainline and the
Cushing Extension. The Mainline is 1,353 miles of 30-inch pipeline from Hardisty, Alberta, to the
United States refineries in Wood River and Patoka, IL. The U.S. portion of the pipeline runs
1,086 miles and begins at the international border in Cavalier County, ND, and has been in
service since June 2010. The Cushing Extension is 298 miles of 36-inch pipeline and associated

facilities that run from Steele City, NE (near the Nebraska-Kansas border) to existing crude oil
terminals and tanks farms in Cushing, OK. The Cushing Extension has been in service since
February 2011.
Keystone XL Pipeline Segments
As proposed in 2008, the Keystone XL pipeline was also to be completed in two phases. As
currently planned, those phases would be constructed as follows:
The Gulf Coast Project, 435 miles of 36-inch pipeline and associated facilities
linking the Cushing tank farms to refineries in Houston and Port Arthur, TX. This
segment includes the Cushing Marketlink project that will provide receipt
facilities to transport U.S. crude oil to the Gulf Coast. TransCanada anticipates
this segment to be in service mid-to-late 2013.
The Keystone XL, 1,179 miles of 36-inch pipeline and associated facilities
linking Hardisty to Steele City. This segment includes the Bakken Marketlink
Project that would provide receipt facilities in Baker, MT, for crude oil from the
Williston Basin producing region for delivery to Steele City then Gulf Coast
refineries. TransCanada expects this segment to be in service late 2015.
The Keystone Pipeline System, with both the completed Keystone and proposed segments of the
Keystone XL, is illustrated in Figure 1.

Source: TransCanada, provided to CRS on May 23, 2012.
TransCanada reports that the Keystone pipeline (the Mainline and Cushing Extension) has the
capacity to deliver 591,000 barrels per day (bpd). TransCanada anticipates that the future addition
of the Keystone XL pipeline (the Keystone XL and Gulf Coast Project) will have an initial
capacity of 700,000 bpd and a potential capacity of 830,000 bpd. As a result, the entire Keystone
Pipeline System may ultimately have a capacity of 1.3 million bpd.10
TransCanada originally estimated the capital cost of the U.S. portion of the Keystone XL pipeline
project, from the U.S. Canada border to Steele City, NE, to be $5.3 billion.11 This figure was
higher than the cost estimate when the initial permit application was filed, reportedly due to
currency swings, changing regulatory requirements, and permitting delays.12 The new route

would presumably be longer and cost more, but specific cost estimates for the reconfigured
Keystone XL project in its entirety are not publicly available and, in any case, would still depend
on the selection of a final route through Nebraska.
The Bakken Marketlink
The Bakken Formation is a large unconventional petroleum and natural gas resource underlying
parts of North Dakota, Montana, and the Canadian provinces of Saskatchewan and Manitoba.
Although the region has been producing since 1951, it is only since 2006 that prices and
technology have made it economic for industry to increase production. In March 2012, Bakken
production reached a new high of over 510,000 bpd, the first time breaking 500,000 bpd.13 In late
2011, Bakken oil production in North Dakota exceeded 500,000 bpd. Depending on the pace of
well development in the region, production is expected to increase steadily.14 To date,
infrastructure to transport oil produced from the Bakken Formation has not kept up with the
increased production. Bakken shale crude oil is transported to refineries by rail and truck, rather
than the more economical pipeline. (For more analysis, see CRS Report R42032, The Bakken
Formation: Leading Unconventional Oil Development
, by Michael Ratner et al.)
As illustrated in Figure 1, the proposed Keystone XL pipeline would include receipt facilities to
transport crude produced from Williston Basin in North Dakota and Montana to Gulf Coast
refineries That project, the Bakken Marketlink, would include facilities to provide crude oil
transportation service from Baker, MT, to Cushing, OK, via the proposed Keystone XL pipeline
and from Cushing to delivery points in Texas, via the proposed Gulf Coast Project.15 Keystone
Marketlink16 estimates that the project will cost $140 million and have the ability to deliver
approximately 150,000 barrels of crude oil per day to the proposed Keystone XL pipeline.17 After
a successful Open Season in late 2010, Keystone Marketlink obtained sufficient commitments to
proceed with the project.18 On August 15, 2011, Keystone Marketlink initiated a second binding
Open Season to obtain additional firm commitments from interested parties for the planned
project.19
These new Bakken contracts improve the economics for Keystone XL, raising the amount of oil
slated to flow through the pipeline.20 Lower transportation costs and access to new markets may
support further investment in the Bakken. Furthermore, TransCanada is not the only company
adding pipeline capacity in the region. Notably, Enbridge, another Canadian pipeline company,
has proposed the Bakken Pipeline Project, which would add 120,000 bpd of transport capacity to

move Bakken oil to Midwest markets.21 According to Enbridge, sufficient pipeline capacity has
been slow to emerge in the region because “they’re smaller players in the Bakken. They are not
able to make the 20-year commitments and it’s been a lot of work to get them to commit to the
level that [is] required to underwrite a major project out of the Bakken.”22 Rail transport capacity
is also expanding.23
Presidential Permit Application Requirements
Ordinarily, federal agencies have no authority to site oil pipelines, even interstate pipelines.24 The
primary siting authority for oil pipelines generally would be established under applicable state
law (which may vary considerably from state to state). However, the construction, connection,
operation, and maintenance of a pipeline that connects the United States with a foreign country
requires executive permission conveyed through a Presidential Permit. Since the Keystone and
proposed Keystone XL pipelines are designed for the importation of oil from Canada, their
facilities require a Presidential Permit.
Executive Order 13337 delegates to the Secretary of State the President’s authority to receive
applications for Presidential Permits.25 Issuance of a Presidential Permit is dependant upon a
finding that the project would serve the “national interest.” In the course of making that
determination, the State Department is obligated to consider a host of issues related to the
proposed project. The State Department will not necessarily evaluate the same factors for each
project seeking a permit. However, the State Department identified the following as key factors it
considered in making previous national interest determinations for pipeline permit applications:
• Environmental impacts of the proposed projects;
• Impacts of the proposed projects on the diversity of supply to meet U.S. crude oil
demand and energy needs;
• The security of transport pathways for crude oil supplies to the United States
through import facilities constructed at the border relative to other modes of
transport;
• Stability of trading partners from whom the United States obtains crude oil;
• Relationship between the United States and various foreign suppliers of crude oil
and the ability of the United States to work with those countries to meet overall
environmental and energy security goals;

24 This is in contrast to interstate natural gas pipelines, which, under Section 7(c) (15 USC §717f(c)) of the Natural Gas
Act, must obtain a “certificate of public convenience and necessity” from the Federal Energy Regulatory Commission.

Transportation Crossings on the International Boundaries of the United States,” 69 Federal Register 25299, May 5,
2004, as amended, and Department of State Delegation of Authority No. 118-2 of January 26, 2006. The source of
Permitting Authority for relevant Executive Orders is discussed further in the Appendix A.

Keystone XL Pipeline Project: Key Issues

• Impact of proposed projects on broader foreign policy objectives, including a
comprehensive strategy to address climate change;
• Economic benefits to the United States of constructing and operating proposed
projects; and
• Relationships between proposed projects and goals to reduce reliance on fossil
fuels and to increase use of alternative and renewable energy sources.26
In making its national interest determination, the State Department is required to consult with
relevant federal and state agencies and to invite public comment in arriving at its determination.
However, the State Department has broad discretion in determining what factors it will examine
to inform its determination and, ultimately, whether a proposed project is in the national interest.
Documenting Environmental Impacts Under NEPA
As identified on the list above, a proposed project’s environmental impact is one factor
considered by the State Department in making its national interest determination, documented
within the context of preparing an Environmental Impact Statement (EIS), pursuant to the
National Environmental Policy Act (NEPA, 42 U.S.C. §4321 et seq.).27 Broadly, NEPA requires
federal agencies to consider the environmental impacts of their actions before proceeding with
them and to inform the public of those potential impacts. To ensure that environmental impacts
are considered, an EIS must be prepared for major federal actions “significantly” affecting the
environment.28 With respect to the 2008 Presidential Permit application submitted by
TransCanada, the State Department concluded that issuance of a permit for the proposed
construction, connection, operation, and maintenance of the Keystone XL Pipeline and its
associated facilities at the United States border would constitute a major federal action that may
have a significant impact upon the environment within the meaning of NEPA.29 For this reason,
the State Department prepared an EIS to address reasonably foreseeable impacts from the
proposed action and alternatives. Similarly, an EIS will have to be prepared for the reconfigured
Keystone XL project under the May 4, 2012, permit application.

26 This list was included in the State Department’s Final Environmental Impact Statement for the Keystone Xl Project
under a discussion regarding the Presidential Permit Review Process (p. 1-4). It was noted that this list is not
exhaustive, and that the State Department may consider additional factors in its national interest determination process.
27 In processing Presidential Permit applications, the State Department is also explicitly directed to review the project’s
compliance with the National Historic Preservation Act (16 U.S.C. §470f), the Endangered Species Act (16 U.S.C.
§1531 et seq.), and Executive Order 12898 of February 11, 1994 (59 Federal Register 7629), concerning environmental
justice. In processing the permit application for the Keystone XL Pipeline project, issues associated with NEPA
compliance have drawn the most attention. In large part, that is likely because it is during the NEPA process that
compliance with these, as well as any other environmental requirements, would be identified, documented, and
demonstrated.

Keystone XL Pipeline Project: Key Issues

Overview of the Process for the 2008 Keystone XL Pipeline Project
Among other requirements, an EIS must include a statement of the purpose and need for an
action, a description of all reasonable alternatives to meet that purpose and need, a description of
the environment to be affected by those alternatives, and an analysis of the direct and indirect
effects of the alternatives, including cumulative impacts.30 Accordingly, the State Department EIS
must demonstrate the review and consider potential environmental impacts of the entire pipeline
(including the construction, operation, and maintenance of the pipeline and its associated
facilities), not just the facilities at the border crossing.
As the NEPA compliance process for TransCanada’s permit application has proceeded, it is
important to understand the distinction between what is required under NEPA itself and what may
be required pursuant to other environmental requirements identified within the context of the
NEPA process. NEPA itself requires federal agencies to identify the environmental impacts of an
action before proceeding with them and to involve the public in that process when environmental
impacts are significant. In that process of identifying a proposed project’s environmental impacts,
within the context of preparing the EIS, the lead agency should identify any compliance
obligations (licenses, permits, or approvals) established under additional state, tribal, and federal
law applicable to the portion of the project constructed in the United States (see “State Siting and
Additional Environmental Requirements,” below).
EIS preparation is done in two stages, resulting in a draft and final EIS. NEPA regulations require
the draft EIS to be circulated for public and agency comment, followed by a final EIS that
incorporates those comments.31 Preparing the EIS is the responsibility of a designated “lead
agency,” in this case, the State Department. In developing the EIS, the State Department must rely
to some extent on information provided by TransCanada. For example, TransCanada’s original
permit application included an Environmental Report which was intended to provide the State
Department with sufficient information to understand the scope of potential environmental
impacts of the project.32
In preparing the draft EIS, the lead agency must request input from “cooperating agencies,”
which include any agency with jurisdiction by law or with special expertise regarding any
environmental impact associated with the project.33 Cooperating agencies for the Keystone XL
project (for the pipeline’s first Presidential Permit application) were the U.S. Environmental
Protection Agency (EPA); the Department of Transportation’s Pipeline and Hazardous Materials
Safety Administration (PHMSA), Office of Pipeline Safety (OPS); the Department of the
Interior’s Bureau of Land Management, U.S. Fish and Wildlife Service, and National Park

30 In preparing an EIS associated with a Presidential Permit, NEPA regulations promulgated by both the Council of
Environmental Quality (CEQ) and the State Department would apply. CEQ regulations implementing NEPA (under 40
C.F.R. §§1500-1508) apply to all federal agencies. NEPA regulations applicable to State Department actions, which
supplement the CEQ regulations, are found at 22 C.F.R. §161.
31 For more analysis of NEPA requirements, see CRS Report RL33152, The National Environmental Policy Act
(NEPA): Background and Implementation
, by Linda Luther.
32 Documents submitted for the initial 2008 Presidential Permit application have now been archived by the State
Department. Documents related to that original application are available at http://keystonepipeline-xl.state.gov/archive/
index.htm.
33 40 C.F.R. §1508.5. Also, Executive Order 13337 directs the Secretary of State to refer an application for a
Presidential Permit to other specifically identified federal departments and agencies on whether granting the application
would be in the national interest.

Service; the U.S. Army Corps of Engineers; the U.S. Department of Agriculture’s Farm Service
Agency, Natural Resources Conservation Service, and Rural Utilities Service; the Department of
Energy’s Western Area Power Administration; and state environmental agencies.
In addition to its role as a cooperating agency, EPA is also required to review and comment
publicly on the EIS and rate both the adequacy of the EIS itself and the level of environmental
impact of the proposed project.34 Rating the EIS takes place after the draft is issued. The EIS
could be rated either “Adequate,” “Insufficient Information,” or “Inadequate.” EPA’s rating of a
project’s environmental impacts may range from “Lack of Objections” to “Environmentally
Unsatisfactory.” In rating the impact of the action itself, EPA would specify one of the following:
“Lack of Objections,” “Environmental Concerns,” “Environmental Objections,” or
“Environmentally Unsatisfactory.” The federal agency would then be required to respond to
EPA’s rating, as appropriate. EPA’s role in rating draft EISs had a significant impact on the NEPA
process for TransCanada’s 2008 Presidential Permit application.
Major milestones in that NEPA process are listed in Table 1, below (for more detail on the

Keystone XL Pipeline Project: Key Issues

The National Interest Determination for a Presidential Permit
Generally, after a final EIS is issued, a federal agency may issue a final record of decision (ROD)
for the project. However, for a Presidential Permit, issuance of the final EIS represents the
beginning of a 90-day public review period during which the State Department gathers
information from necessary to inform its national interest determinations. Ultimately, a decision
regarding issuance of a Presidential Permit for a pipeline project would be reflected in a
combined “Record of Decision and National Interest Determination,” issued by the State
Department.35 That document, required under elements of both NEPA and E.O. 11424, formalizes
the selection of a project alternative.
The process of determining a project’s national interest illustrates the distinctly different, yet
interrelated requirements applicable to the NEPA process and the Presidential Permit application
process. Under NEPA, the State Department (or any other federal agency considering an action)
must fully assess the environmental consequences of an action and potential project alternatives
before making a final decision. NEPA does not prohibit a federal action that has adverse
environment impacts; it requires only that a federal agency be fully aware of and consider those
adverse impacts before selecting a final project alternative. That is, NEPA is intended to be part of
the decision-making process, not dictate a particular outcome. By contrast, issuance of a
Presidential Permit is predicated on the Secretary of State finding that the proposed project would
serve the national interest. While NEPA does not prohibit federal actions with adverse
environmental impacts, a project’s adverse environmental impacts (as well as other factors) may
lead the State Department to determine that it is not in the national interest.
Overview of the Process for the 2008 Keystone XL Pipeline Project
During the 90-day public review period for the initial Keystone XL pipeline permit, the State
Department held public meetings in each of the six states through which the proposed pipeline
would pass and in Washington, DC.36 The meetings were intended to give members of the public
additional opportunity to voice their opinions on issues they thought should be taken into account
in determining whether granting or denying the Presidential Permit would be in the national
interest. During the review period, the State Department received input from state, local, and
tribal officials as well as members of the public.
On November 10, 2011, during the public review period, the State Department issued a statement
regarding the public comments and its response to those comments.37 The department stated that
it received comments on a wide range of issues including the project’s potential impact on jobs,
pipeline safety, health concerns, the societal impact of the project, and oil extraction in Canada.
Concern regarding the proposed pipeline route through the Sand Hills area of Nebraska was
identified as one of the most common issues raised. Comments regarding that pipeline route were
consistent with the environmental impacts identified in the final EIS with regard to the unique

combination of characteristics of the Sand Hills region (e.g., a high concentration of wetlands of
special concern, a sensitive ecosystem, and extensive areas of very shallow groundwater).
Further, the Nebraska legislature convened a special session to consider the legislation that would
establish regulations applicable to pipeline siting within the state.
Facing the prospect of new state pipeline siting regulations applicable to the Sand Hills, together
with the concern about the Keystone XL pipeline’s specific “preferred” route, the State
Department announced that it needed additional information about alternative pipeline routes
avoiding the environmentally sensitive Sand Hills area in Nebraska before moving forward with
its national interest determination.38 Although the State Department did not decide that
environmental issues led to a determination that the proposed project was not in the national
interest, environmental issues identified in the final EIS, and further stressed in public comments,
led to its decision to delay that determination until it gathered this information. In a concurrent
press release, President Obama stated
Because this permit decision could affect the health and safety of the American people as
well as the environment, and because a number of concerns have been raised through a
public process, we should take the time to ensure that all questions are properly addressed
and all the potential impacts are properly understood.39
Subsequently, TransCanada announced that it would work with the State Department and the
Nebraska Department of Environmental Quality (DEQ) to conduct an environmental assessment
to define the best location for the Keystone XL pipeline in Nebraska. Further, the company stated
that it would “cooperate with these agencies and provide them with the information they need to
complete a thorough review that addresses concerns regarding the Sandhills region.”40
Although no new decision deadline was established, State Department officials suggested that it
would be “reasonable to expect that this process including a public comment period on a
supplement to the final EIS consistent with NEPA could be completed as early as the first quarter
of 2013.”41 In a prior press interview, President Obama also appeared to suggest that,
notwithstanding the delegation of Presidential Permit authority to the State Department, he would
be personally involved in the final decision on the Keystone XL Pipeline permit application.42
As noted previously, on December 23, 2011, the Temporary Payroll Tax Cut Continuation Act of
2011 was enacted (P.L. 112-78). Under Section 501, “Permit for Keystone XL Pipeline,” the
Secretary of State was required to grant the Presidential Permit for the Keystone XL pipeline
project within 60 days, unless the President determined that the pipeline would not be in the
national interest. On January 18, 2012, the State Department announced, with the President’s
concurrence, that the Presidential Permit for the proposed Keystone XL Pipeline would be denied
at that time because it was determined not to serve the national interest. That recommendation
“was predicated on the fact that the Department does not have sufficient time to obtain the

Keystone XL Pipeline Project: Key Issues

Presidential Permit Application for the Reconfigured Keystone XL
On February 27, 2012, in the wake of the Presidential Permit denial, TransCanada advised the
State Department of its intent to file a new Presidential Permit application with an alternative
route in Nebraska.44 On April 19, 2012, the Nebraska DEQ received TransCanada’s Initial Report
Identifying Alternative and Preferred Corridors for Nebraska Reroute
route.45 Public meetings on
the newly proposed routes were scheduled for May 9-17. On May 4, 2012, TransCanada
submitted a new application for a Presidential Permit authorizing the construction, connection,
operation, and maintenance of pipeline facilities for the importation of crude oil at the United
State-Canada border. 46
On September 5, 2012, TransCanada submitted to the Nebraska DEQ a Supplemental
Environmental Report (SER) detailing its preferred alternative route for the Keystone XL
Pipeline in Nebraska. The reconfigured Keystone XL pipeline project would cross the border at
Phillips County, MT, and extend to a point on the existing Keystone pipeline system at Steele
City, NE. Compared to the route proposed in the 2008 permit application, changes to the route
involve only the segment through Nebraska. TransCanada’s SER served as the basis for the state’s
draft evaluation of the new route, which the DEQ completed and made public on October 4,
2012.47 The DEQ announced that it would hold a public comment period on the draft evaluation
report to be concluded at a public hearing scheduled for December 4, 2012.48
The Gulf Coast Project, now proceeding as a standalone project (illustrated in Figure 1), does not
involve an international border crossing. As a result, that segment of the Keystone XL pipeline
system is not included as part of the Presidential Permit application. (However, as a pipeline
carrying a hazardous material, this pipeline segment must still comply with a range of state and
federal permit, approval, and consultation requirements, see “State Siting and Additional
Environmental Requirements.”)
Had the State Department been allowed to continue its national interest determination, as it
originally proposed in November 2011, it could have completed the NEPA process with only the
publication of a supplemental EIS that included analysis of new routes through Nebraska.
However, denial of the Presidential Permit ended the NEPA process for the 2008 project. With the
new Presidential Permit application, the State Department must begin a new NEPA process and,
eventually, determine whether that project would serve the national interest.49

Keystone XL Pipeline Project: Key Issues

On June 15, 2012, the State Department published a Notice of Intent (NOI) to prepare a
Supplemental EIS for the new Keystone XL pipeline permit application.50 It will supplement the
August 26, 2011, final EIS to include information and analysis about potential impacts associated
with the new proposed route within Nebraska. It will also include any other subjects that may
need to be updated as a result of significant new circumstances or information relevant to
environmental concerns related to the May 2012 permit application.
Although EIS preparation will involve supplementing previously produced documents, the State
Department is obligated to complete certain steps of the NEPA process again. In particular, the
department is obligated to allow for public scoping of the project; prepare both a draft and final
EIS; and respond to public and agency comments on those documents. In particular, as
announced in the State Department June NOI, the department included public participation in the
scoping process for the supplemental EIS (which ended on July 30, 2012). After this process, a
draft supplemental EIS will be published and mailed to relevant federal, state, and local
government agencies, elected officials, environmental and public interest groups, Indian tribes,
affected landowners, commenters, local libraries, newspapers, and other interested parties. The
State Department will then consider comments on the draft supplemental EIS and revise the
document, as necessary, before issuing a final supplemental EIS.
State Siting and Additional Environmental Requirements
As stated above, the federal government does not currently exercise siting authority over oil
pipelines. Instead, siting for the Keystone XL pipeline must comply with any applicable state
law—which can vary from state to state. South Dakota, for example, required TransCanada to
apply for a permit for the Keystone XL pipeline from the state public utility commission, which
issued the permit on April 25, 2010.51 Montana requires a certificate from the state’s Department
of Environmental Quality.52
At the time of TransCanada’s initial application for a Presidential Permit, Nebraska did not have
any permitting requirements that applied specifically to the construction and operation of oil
pipelines, although a state statute does include an “eminent domain” provision, which grants
eminent domain authority to oil pipeline companies that are unable to obtain the necessary
property rights from the relevant property owners.53 However, due to the controversy surrounding
the Keystone XL project, Nebraska’s governor called a special session of its legislature to enact
legislation to assert state authority over pipeline siting. Subsequently, the state enacted two
laws—one that would affect the siting of the Keystone XL pipeline (see Table 1) and one that

outlines procedures for siting any future oil pipeline in Nebraska.54 The latter will require an oil
pipeline carrier proposing to construct a major oil pipeline in Nebraska to file an application with
the state’s Public Service Commission and receive approval before beginning construction.
Additionally, the law authorized the commission to follow certain procedures before deciding
whether a proposed oil pipeline would serve the public interest.
Although there are limited federal requirements applicable to oil pipeline siting, there are
numerous local, state, tribal, and federal requirements applicable to pipeline construction,
operation, and maintenance. For example, the August 2011 final EIS for the Keystone XL
pipeline identified a list of permits, licenses, approvals, and consultation that would be required
before the pipeline project could proceed.55 From that list, following are a few of the requirements
that would likely apply to any pipeline project, listed by agency with jurisdiction over that
requirement:
• The U.S. Army Corps of Engineers—issuance of a permit for sections of the
project that require placement of dredge and fill material in waters of the United
States, including wetlands (pursuant to Section 404 of the Clean Water Act), or
for pipeline crossings of navigable waters (pursuant to Section 10 of the Rivers
and Harbors Act);
• The Environmental Protection Agency—review and issue National Pollutant
Discharge Elimination System permits for the discharge of pollutants in state
waters (pursuant to Section 402 of the Clean Water Act);
• The Bureau of Land Management—grant temporary use permits for portions of
the project that would encroach on federal lands;
• U.S. Fish and Wildlife Service—consider impacts to federally listed endangered
species (pursuant to the Endangered Species Act) and provide a Biological
Opinion if the project is likely to adversely affect federally listed species.
• Multiple state/county agencies—consult on and/or consider issuance of permits
for projects that cross navigable waters or state highways, or involve work
potentially affecting state streams, cultural resources, or natural resources.
The time it takes to complete the NEPA process has been a focus of attention for the first
Presidential Permit application for the Keystone XL pipeline. However, for past pipeline projects,
obtaining all required local, state, tribal, and federal permits, approvals, and licenses may take a
similar amount of time. By way of example, for the Alberta Clipper pipeline project (another oil
sands pipeline) completion of the NEPA process, the national interest determination and issuance
of a Presidential Permit took approximately two years. Obtaining the necessary permits,
approvals, and licenses for construction of the pipeline took an additional two years.

Keystone XL Pipeline Project: Key Issues

Legislative Efforts to Change Permitting Authority
In light of the State Department’s denial of the initial Keystone XL permit, some in Congress
have sought alternative means to support development of the pipeline. As stated in the
“Introduction,” there are a number of legislative proposals to change the federal permitting
authority for the pipeline. H.R. 3548 would transfer the permitting authority over the Keystone
XL pipeline project from the State Department to the Federal Energy Regulatory Commission
(FERC), requiring the commission to issue a permit for the project within 30 days of enactment.56
Other proposals, such as H.R. 3811 and S. 3445, would directly shift permitting authority to
Congress, effectively approving upon enactment the permit applications filed by TransCanada in
2008 and 2012, respectively.
Changing, or eliminating altogether, the State Department’s role in issuing cross-border
infrastructure permits may raise questions about the President’s executive authority (further
discussed in the Appendix A). In response to H.R. 3548, for example, the State Department’s key
official on Keystone XL testified before Congress:
The legislation raises serious questions about existing legal authorities, questions the
continuing force of much of the federal and all of the state and local environmental and land
use management authority over the pipeline, and overrides foreign policy and national
security considerations implicated by a cross border permit, which are properly assessed by
the State Department.57
Such proposals may also raise some administrative and legal challenges for FERC or other
federal agencies. A senior FERC official testified that a proposal like H.R. 3548 does not provide
enough time for an “adequate” public record, provides no clear authority for enforcing measures
required in the EIS, does not articulate a process for authorizing alterations to the pipeline route
in Nebraska, and is unclear about permits required from other federal agencies, among other
concerns.58 For additional analysis of associated legal issues, see CRS Report R42124, Proposed
Keystone XL Pipeline: Legal Issues
, by Adam Vann, Kristina Alexander, and Kenneth R. Thomas.
Given the State Department’s initial permit denial, and opposition from various environmental
groups and stakeholders along the pipeline route, legal challenges are a possibility. However, in
the event of a challenge based on an environmental issue, the distinction between State
Department actions required under NEPA and those required under its authority to issue a
Presidential Permit would be relevant. NEPA does not create a private right of action. Instead,
judicial challenges to a federal agency action under NEPA are brought pursuant to the
Administrative Procedure Act (APA, 5 U.S.C. §§706 et seq.). Presidential actions, however, are
not subject to judicial review under the APA.59 That is, the final agency action reflected in an

56 The Surface Transportation Extension Act of 2012, Part II (H.R. 4348), which passed in the House on April 18,
2012, also contained these provisions, but they were subsequently dropped from the bill in conference committee with
the Senate.

ROD is subject to judicial review, but the State Department’s national interest determination,
made under its authority to issue a Presidential Permit, is not. For more analysis of the State
Department’s authority to grant a Presidential Permit, see Appendix A.
Arguments For and Against the Pipeline
Proponents of the Keystone XL pipeline, including Canadian agencies and U.S. and Canadian
petroleum industry stakeholders, base their arguments supporting the pipeline primarily on
increasing the diversity of the U.S. petroleum supply and economic benefits, especially jobs.
Pipeline opponents are generally environmental organizations and community groups. Their
concerns stem from issues that can be broadly categorized as the pipeline’s global or community
impacts. “Global” impacts stem primarily from concern regarding the lifecycle greenhouse gas
(GHG) emissions associated with the development of Canadian oil sands, compared to
conventional oil or renewable fuels. Although the concern regarding GHG emissions is focused
primarily on the extraction process, opponents also argue that use of the oil sands crude promotes
continued U.S. dependency on fossil fuels. Concern over adverse community impacts of the
pipeline stems primarily from impacts associated with the pipeline’s construction and long-term
use on private land—particularly its potential to affect agricultural uses and cattle grazing.
Communities along the pipeline route are also concerned about the risk of a potential release of
heavy crude and the operators’ ability to respond to a release, particularly in remote areas.
Impacts to the Nebraska Sand Hills
In the process of examining factors necessary to determine whether the Presidential Permit for the
original Keystone XL pipeline route was in the national interest, the State Department decided
that it needed to assess potential alternative pipeline routes that would avoid the Sand Hills region
of Nebraska. Unique characteristics of the Sand Hills—including its high concentration of
wetlands, extensive areas of very shallow groundwater, and its sensitive ecosystem—were
identified as factors that resulted in increasing public concern over the proposed pipeline location.
For these reasons, TransCanada announced it would work with the Nebraska DEQ to identify a
potential pipeline route that would avoid the Sand Hills.
To understand concerns about the potential environmental impacts of a pipeline crossing the Sand
Hills (also referred to as the Sandhills), an understanding of the unique size and structure of the
region is useful. The Sand Hills region is a 19,600 square mile sand dune formation stabilized by
native grasslands that cover 95% of its surface. The surface is highly susceptible to wind erosion
if the grassland is disturbed.60 Below its surface lie hundreds of feet of coarse sand and gravel.
Essentially, the porous soil acts like a giant sponge that quickly absorbs precipitation, allowing
very little to run off. In some areas, the water table reaches the land surface—a characteristic that
creates lakes that dot the region as well as 1.3 million acres of wetlands. The loose, porous soil
and sensitivity to wind erosion have been factors contributing to a lack of development on the

Sand Hills. As a result, the region contains the most intact natural habitat of the Great Plains of
the United States. The porosity of the soil is also relevant because the Sand Hills sits atop the
Ogallala Aquifer—one of the largest freshwater aquifer systems in the world.61
The highly porous soil of the Sand Hills makes it a significant recharge zone in the northern
Ogallala Aquifer. That is, the sandy, porous soil of the Sand Hills allows a significant amount of
surface water to enter (recharge) the aquifer system. Water from the aquifer also accounts for a
significant amount of water use—78% of the region’s public water, 83% of irrigation water in
Nebraska, and 30% of water used in the United States for irrigation and agriculture.
Potential impacts to the Ogallala Aquifer and the Sand Hills identified in the final EIS for
TransCanada’s original permit application included groundwater contamination after an
accidental spill or leak of crude oil during the construction or operation of the proposed pipeline.
Along the preferred route of the originally proposed pipeline configuration, areas in the Sand
Hills region were identified as locations where the water table may be close to the surface. The
depth to groundwater was less than 10 feet for approximately 65 miles of the preferred pipeline
route in Nebraska. Both the soil porosity and the close proximity of groundwater to the surface
increase the potential that a release of oil from the pipeline could contaminate groundwater in the
region.62 The new route alternative TransCanada has proposed for the Nebraska section of the
Keystone XL pipeline avoids the Sand Hills and certain areas nearby with similar soil properties
(Figure 2). However, the pipeline would still cross part of the Ogallala aquifer.

61 The entire Ogallala Aquifer system stretches across eight states generally from north to south to include South
Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas and underlies about 174,000
square miles.
62 Generally, a release of crude oil to land would not necessarily result in groundwater contamination. In addition to the
depth from the land surface to groundwater and the characteristics of the environment into which the crude oil is
released (e.g., characteristics of the underlying soils), the potential for crude oil to reach groundwater would depend on
factors such as the volume of the spill, the duration of the release, and the viscosity and density of the crude oil.

Impact on U.S. Energy Security
In its Presidential Permit application, TransCanada asserts that constructing the proposed
Keystone XL pipeline is in the U.S national interest to maintain adequate crude oil supplies for
U.S. refineries. The application argues that the pipeline will allow U.S. refiners to substitute
Canadian supply for other foreign crude supply and to obtain direct pipeline access to secure and
growing Canadian crude output. In particular, the application asserts that the pipeline would allow
the United States to decrease its dependence on foreign crude oil supplies from Mexico and
Venezuela, the two largest oil exporters into the U.S. Gulf Coast.63 Consistent with this argument,
H.R. 3900 would seek to ensure that any crude oil and bitumen transported by the Keystone XL
pipeline, or any resulting refined products, would have to remain in U.S. markets subject to a
presidential waiver allowing foreign export.64 Depending upon the circumstances, however, such

Representative Edward Markey containing similar export restrictions.

restrictions could raise concerns with respect to international trade agreements, among other
considerations.
Energy security arguments have taken on additional weight in light of the recent geopolitical
tensions in the Middle East and North Africa. However, it is worth noting that even if Keystone
XL is built, prices for the crude oil it carries as well as for domestically produced oil from
elsewhere will continue to be affected by international events. The oil market is globally
integrated and events in major producer and consumer countries can affect prices everywhere.65
For example, the disruption of Libyan supply in early 2011 contributed to higher crude oil prices
in the United States, even though the United States imported almost no oil from Libya before the
unrest broke out.66
Canadian Oil Imports in the Overall U.S. Supply Context67
Gross U.S. imports of crude oil and petroleum products averaged 11.4 million bpd (Mbpd) in
2011.68 U.S. oil exports averaged 2.9 Mbpd (almost entirely petroleum products), leaving net
imports at 8.4 Mbpd.69 U.S. net imports have fallen by 4.1 Mbpd or 33% since they peaked in
2005 as a result of lower total oil consumption and higher domestic production. Some of this
decline could be mitigated in the near term as oil demand recovers from the recession. However,
there is increasing sentiment among forecasters that U.S. oil imports have passed their high water
mark already and may remain relatively flat or fall in the foreseeable future.70
Among the largest sources of U.S. gross oil imports are Canada (2.7 Mbpd), the Persian Gulf (1.9
Mbpd), Mexico (1.2 Mbpd), and Venezuela (0.9 Mbpd). Imports from the latter two sources have
decreased in recent years in part due to lower need for imports described above and in part due to
developments in those countries. Mexican production has been falling since 2004 because new oil
developments have not been able to offset depletion at Mexico’s giant Cantarell field. Imports
from Venezuela, another key source of U.S. imports, have also fallen. Venezuelan production
never fully recovered after a strike at its national oil company, Petróleos de Venezuela, in 2002-
2003. Venezuelan production today is nearly 1 Mbpd less than that achieved in 2001. In recent
years, Venezuela has also been trying to diversify business away from the United States, for
example, by increasing exports to China.71

65 This is the case unless the oil is stranded due to transport bottlenecks. Ironically, the bottleneck for crude oil flowing
south from the Midwest to the Gulf Coast—which Keystone XL would help alleviate—helped insulate Midwestern
crude oil prices from the impacts of unrest in the Middle East and North Africa. However, as is discussed below, this
may have benefited Midwestern refiners but probably did not significantly reduce costs for U.S. consumers.

69 For context, the United States consumed 18.8 Mbpd in 2011, more than 20% of the world’s oil market. Net imports
are gross or total imports less total exports. This section will focus on gross imports, though it should be noted that
among U.S. petroleum exports about 0.2 Mbpd of petroleum products go to Canada and 0.4 Mbpd to Mexico.

Meanwhile, Canadian production and exports to the United States have increased, primarily due
to growing output from the oil sands in western Canada. Energy markets in the United States and
Canada are well integrated by pipeline infrastructure; nearly all Canadian energy exports go to the
United States.72 Canadian oil production has increased about 0.2 Mbpd since 2005 and exports to
the United States have increased by 0.5 Mbpd (see Figure 3).73 Some expect Canadian oil
production to grow by nearly 2 Mbpd by 2025 due to increased output from the oil sands.74

Oil Sands, Keystone XL, and the U.S. Oil Market
Oil sands (also referred to as tar sands) are a mixture of clay, sand, water, and heavy black
viscous oil known as bitumen. Oil sands require more processing than conventional crude oil. Oil
sands are processed to extract the bitumen, which can then be sent to refineries in one of two
forms. Bitumen can be upgraded into “syncrude,” a light crude that is suitable for pipeline
transport and is relatively easy to refine. Alternatively, bitumen can be blended with lighter

to be higher than the increment in production.

Keystone XL Pipeline Project: Key Issues

hydrocarbons to form a heavy crude (diluted bitumen or “dilbit”) that can be transported by
pipeline. The bulk of oil sands supply growth is expected to be in the form of the latter.75
Most oil sands imports into the United States currently go to the Midwest, where refineries have
been investing in complex refining capacity to process growing volumes of heavy Canadian
crude.76 The U.S. Gulf Coast region already has a large amount of complex refining capacity and
is well suited for processing Canadian heavy crude oil. Gulf Coast refiners currently process
heavy crudes from Venezuela, Mexico, and elsewhere. Complex refineries in the Gulf Coast may
be best equipped to handle a large increase of heavy oil sands crude, though they may still need to
adjust processes and make new capital investments in equipment to accommodate particular
crudes’ characteristics,77 especially if the new Canadian crudes will be used in large amounts.78
There are 15 refineries within Keystone XL’s (technically, the Gulf Coast Project’s) proposed
delivery area in Texas that currently process heavy crude oil similar in composition to the oil that
Keystone XL pipeline would carry.79
Oil production from the oil sands is increasing, as is production from the Bakken and other areas
of the U.S. Midwest.80 Transport options to carry crude from the Midwest to the Gulf Coast are
limited. (In the past, crude oil had been shipped up from the Gulf Coast to Midwestern refineries.)
The resulting abundance of crude oil in the Midwest has driven down crude oil prices in that
region relative to Gulf Coast and international crude markets. Midwestern refiners benefit from
the lower cost of crude, but it does not translate to substantially lower consumer prices for
gasoline or other products in the region. The Midwest still brings in refined products from the
Gulf Coast, which keeps refined products prices in line with national and international levels.81
Oil sands producers are interested in Keystone XL because it would expand their market reach
into the Gulf Coast. The Gulf Coast region holds half of U.S. refining capacity, including a
substantial amount of technologically advanced capacity capable of processing heavy sour crudes
in large volumes. Reaching a larger market and one with more advanced refining capacity could
increase the price these producers receive for their crude. For their part, Gulf Coast refiners are
interested in the Keystone XL pipeline because it increases the supply of heavy sour crude in the
Gulf region, potentially bringing down their input costs relative to the options they currently have
available. Canadian Natural Resources Limited, an oil sands producer, and Valero Energy
Corporation, a large U.S. refiner, are among those that contracted for shipping capacity on the
Keystone XL pipeline.

Keystone XL Pipeline Project: Key Issues

With expanded pipeline capacity extending to the U.S. Gulf Coast, Canadian oil sands crude may
compete with other heavy crudes such as those from Mexico, Venezuela, and elsewhere.82 It is
difficult to predict precisely how this competition will play out, but it may take place through
shifting discounts or premiums on crude oils from various sources.83 It may be possible for
Canadian oil supplies to effectively “push out” waterborne shipments from other countries,
although this depends on a wide range of market conditions. Waterborne crudes may more easily
go to other destinations than Canadian crudes, though like Canadian crudes they can be tied to
specialized refining capacity, as is true for Venezuelan heavy crudes.
There is concern that increased supply of crude to the Gulf Coast may result in larger petroleum
product exports rather than contributing to lower domestic fuel cost. Although the United States is
a net importer of oil and petroleum products, it does export some petroleum products. U.S.
petroleum product exports rose when domestic demand declined in the wake of the recession
while foreign demand for certain fuels, such as diesel, remained relatively robust. Issues around
potential export of Canadian crude oil carried on Keystone XL or export of products made from
that crude oil are addressed in CRS Report R42465, U.S. Oil Imports and Exports, by Robert
Pirog.
If Keystone XL secures growing oil sands output for the United States, it could push out seaborne
crudes from elsewhere, regardless of where the product is ultimately sold. If the absence of the
pipeline encourages Canadian oil sands producers and pipeline companies to find an alternate
export route through the Canadian West Coast, Canadian supplies may displace heavy oil supplies
in other markets and potentially allow relatively more overseas imports coming into the Gulf
Coast. This possibility is discussed further below.
It should be noted that Keystone XL aims to alleviate two potential bottlenecks in the pipeline
transportation system: Between Western Canada and the United States, and between the U.S.
Midwest and the Gulf Coast. Existing pipelines between Canada and the United States have spare
capacity to carry rising Canadian production for the time being. According to some estimates,
additional capacity, such as Keystone XL, may not be needed until 2019.84 The latter bottleneck,
between the Midwest and the Gulf Coast, is already at capacity and, as described above, has
resulted in a discount for crude oil in the Midwest (though not for petroleum products). The Gulf
Coast Pipeline Project, the lower leg of originally proposed Keystone XL pipeline, would address
this second bottleneck and help alleviate the discount for Midwestern crudes.
Other Pipeline Projects
Apart from Keystone XL, several other pipeline proposals could help carry growing Canadian
crude oil supplies to the U.S. Gulf Coast. On October 16, 2011, Enbridge announced it would
purchase ConocoPhillips’ share of the Seaway pipeline and reverse its direction to bring crude oil
from the Midwest to the Gulf Coast. ConocoPhillips had kept the pipeline running northward to
serve its refinery in Ponca City, OK. However, the glut of oil in the Midwest had resulted in the

pipeline running at low volumes. Nonetheless, ConocoPhillips had been uninterested in reversing
the pipeline. ConocoPhillips, which is spinning off its refining business,85 sold its share of
Seaway to Enbridge. Enbridge and Seaway shareholder Enterprise Products Partners L.P. are
reversing the direction of crude oil flows on the Seaway pipeline to enable it to transport oil from
Cushing, OK, to the U.S. Gulf Coast. The pipeline is expected to start running southward at an
initial capacity of 150,000 bpd starting in May 2012, with capacity expected to increase to
400,000 bpd in 2013. The reversal is expected to reduce the glut of crude oil in the Midwest and
reconnect Midwestern crude prices to global prices (driving the U.S. Benchmark West Texas
Intermediate crude higher).86
Prior to the Seaway sale, Enbridge had reported significant commitments for two new pipeline
projects: Flanagan South, which would carry oil from Illinois to Oklahoma, and Wrangler, which
would carry oil from Oklahoma to Texas.87 According to Enbridge, the project would duplicate
existing routes and would not cross an international border, so it would not require a Presidential
Permit. Enbridge already has cross border pipeline capacity connecting Alberta to Illinois.
However, according to press reports, Wrangler has been canceled in light of the Seaway purchase
and reversal.88 Enbridge is moving forward with the Flanagan South project, which will have an
initial capacity of about 600,000 bpd and run alongside Enbridge’s existing Spearhead pipeline
(see Figure 4).89 Like Keystone XL/Gulf Coast Project, Flanagan South and a southbound
Seaway may facilitate increased flow of Canadian crude to the U.S. Gulf Coast.

Canadian Oil to Alternative Markets
There are proposals to increase the capacity for oil from Alberta to reach the Canadian east and
west coast. Currently, nearly all of Canada’s oil exports go to the United States, mostly through
north-south pipelines. Only one major oil pipeline extends from Alberta to Canada’s west coast:
the Trans Mountain Pipeline, which is owned by Houston-based Kinder Morgan and has a
capacity of 300,000 bpd. Some of the oil from the Trans Mountain Pipeline is loaded onto tankers
and shipped from Vancouver. Nearly all of the quantities shipped by sea go to the United States,
though a small amount goes to China and other Asian countries.90 Proposals for additional east
and westbound capacity include:
• Kinder Morgan has plans to expand the Trans Mountain Pipeline to 850,000 bpd
by 2017, more than doubling its existing capacity, and expanding west coast
shipping facilities.91 The expansion has received the necessary commitments
from parties interested in shipping additional crude volumes. Some shippers are

interested in using the additional capacity to export more Canadian crude oil to
Asia. Kinder Morgan still needs regulatory approvals from Canadian authorities
and is working to gain the support of stakeholders.92 There is some opposition to
the project, including from groups concerned about additional tanker traffic near
Vancouver and potential oil spill risks.93
• Enbridge has proposed a new pipeline: the Northern Gateway project would have
a 525,000 bpd capacity to send oil from Edmonton to Kitimat, British
Columbia.94 However, Northern Gateway faces opposition from groups including
some First Nations communities and environmental groups.95
• Several projects are considering moving oil east rather than to the west coast.
According to reports, TransCanada is considering a pipeline project sending oil
east from Alberta to Quebec and New Brunswick which could also carry crude
bound for export.96 Enbridge is also interested in expanding eastbound capacity
by reversing its Line 9 Pipeline.97 Some suggest this could potentially lead to oil
sands crude traveling east, through Montreal and then through another pipeline to
Portland, ME, from which point it could be exported.98 As with other pipeline
projects, these also face opposition from environmental groups concerned about
oil spill risks and/or generally opposed to oil sands development.
These projects reflect anticipated growth of western Canadian oil production and an interest by
Canadian oil producers to diversify their available markets beyond U.S. customers, including to
reach rapidly growing Asian oil demand. Proposals have received criticism from
environmentalists. Because it would require construction of a completely new pipeline, Northern
Gateway in particular has been criticized by some environmental and First Nations groups.99
Canadian interests assert that Canadian oil sales to Asian markets, where oil demand is growing
rapidly, are more likely if greater shipments to the United States are not possible.100 A study
commissioned by the U.S. Department of Energy suggested that:
if pipeline projects to the BC [British Columbia] coast are built, they are likely to be utilized.
This is because of the relatively short marine distances to major northeast Asia markets,

future expected growth there in refining capacity and increasing ownership interests by
Chinese companies especially in oil sands production. Such increased capacity would alter
global crude trade patterns. Western Canadian Sedimentary Basin (WCSB) crudes would be
“lost” from the USA, going instead to Asia. There they would displace the world’s balancing
crude oils, Middle Eastern and African predominantly OPEC grades, which would in turn
move to the USA. The net effect would be substantially higher U.S. dependency on crude
oils from those sources versus scenarios where capacity to move WCSB crudes to Asia was
limited.101
Economic Impact of the Pipeline
In addition to supply diversity arguments, some Keystone XL pipeline proponents support the
project based on economic benefits associated with expanding U.S. pipeline infrastructure. A
recent study by the Energy Policy Research Foundation, for example, concludes that “the
Keystone expansion would provide net economic benefits from improved efficiencies in both the
transportation and processing of crude oil of $100 million-$600 million annually, in addition to an
immediate boost in construction employment.”102 A 2009 report from the Canadian Energy
Research Institute (CERI) commissioned by the American Petroleum Institute similarly
concludes that
As investment and production in oil sands ramps up in Canada, the pace of economic activity
quickens and demand for US goods and services increase rapidly, resulting in an estimated
343 thousand new US jobs between 2011 and 2015. Demand for U.S. goods and services
continues to climb throughout the period, adding an estimated $34 billion to US GDP in
2015, $40.4 billion in 2020, and $42.2 billion in 2025.103
These CERI estimates apply to the entire oil sands industry, however, not only the Keystone XL
project, and they are derived from a proprietary economic analysis which has not been subject to
external review. Some stakeholders point to State Department and other studies reporting much
lower anticipated economic benefits.104 Consequently, it is difficult to determine what specific
economic and employment impacts may ultimately be attributable to the Keystone XL pipeline.
Nonetheless, given the physical scale of the project, it could be expected to increase employment
and investment at least during construction.
Lifecycle Greenhouse Gas Emissions
Oil production from oil sands is controversial because it has significant environmental impacts,
including emissions of greenhouse gases during extraction and processing, disturbance of mined

Keystone XL Pipeline Project: Key Issues

land, and impacts on wildlife and water quality.105 Because bitumen in oil sands cannot be
pumped from a conventional well, it must be mined, usually using strip mining or open pit
techniques, or the oil can be extracted with underground heating methods.106 Large amounts of
water and natural gas are also required (for heating) during the extraction process.107 The
magnitude of the environmental impacts of oil sands production, in absolute terms and compared
to conventional oil production, has been the subject of numerous, and sometimes conflicting,
studies and policy papers.108 Some stakeholders who object to oil sands projects oppose the
Keystone XL pipeline because it expands access to new markets for the oil produced by those
projects, thereby encouraging what they consider to be further environmentally destructive oil
sands development. As discussed earlier, however, if oil sands production can be diverted to other
markets (e.g., Asia), preventing the Keystone XL project may not necessarily limit oil sands
development.109
Some stakeholders object to the Keystone XL pipeline because it would increase U.S. supplies of
oil, and thereby perpetuate the nation’s dependence on imported fossil fuels and increase carbon
emissions from the transportation sector.110 Acknowledging this concern, in a public forum on
October 20, 2010, Secretary of State Clinton reportedly remarked that “we’re either going to be
dependent on dirty oil from the [Persian] Gulf or dirty oil from Canada … until we can get our act
together as a country and figure out that clean, renewable energy is in both our economic interests
and the interests of our planet.”111 Critics of the State Department’s draft and supplemental draft
EIS assert that the environmental review overlooks the pipeline project’s overall impact on
greenhouse gas emissions, for example, from the extraction and refining processes. To address
those potential emissions, EPA recommended that the final EIS include discussion of mitigation
approaches for greenhouse gas emissions from extraction activities that are either currently used
or could be employed to help lower lifecycle greenhouse gas emissions.112 However, others have
argued that whether the Keystone XL Pipeline is constructed would have little bearing on
greenhouse gas emissions as there are likely to be other export routes available for Canadian oil
sands crude, and therefore, the same crude oils would still be transported and refined, albeit in
different locations.113 For further analysis of greenhouse gas emissions associated with the

Keystone XL Pipeline Project: Key Issues

Greenhouse Gas Emissions
, by Richard K. Lattanzio.
Land Use and Oil Spill Impacts
For the pipeline project represented in the August 2011 final EIS, approximately 95% of the land
affected by pipeline construction and operation was privately owned, with the remaining 5%
almost equally state and federal land. Private land uses were primarily agricultural—farmers and
cattle ranchers.
The pipeline’s construction and continued operation would involve a 50-foot-wide permanent
right-of-way along the length of the pipeline. Keystone agreed to compensate landowners for
losses on a case-by-case basis. However, a concern among landowners and communities along
the route is the potential for their land or water (used for drinking, irrigation, or recreation) to be
contaminated by an accidental release (spill) of oil. That concern is heightened in areas where the
pipeline will be located near or would cross water or is in a remote location.
A primary environmental concern of any oil pipeline is the risk of a spill. In estimating the
possible impacts of an oil spill, location is generally considered the most important factor—
particularly the potential for the spill to reach surface or groundwater. For example, the potential
impacts of a spill to water is highlighted in the Keystone XL final EIS, as follows:
The greatest concern would be a spill in environmentally sensitive areas, such as wetlands,
flowing streams and rivers, shallow groundwater areas, areas near water intakes for drinking
water or for commercial/industrial uses, and areas with populations of sensitive wildlife or
plant species.114
A release of oil on land would not necessarily result in surface or groundwater contamination.
The potential for a spill to reach water would depend on factors such its proximity to a water
source (e.g., on or near a creek or stream or located on land where the groundwater table is close
to the surface) and the characteristics of the environment into which the crude oil is released (e.g.,
porous underlying soils), and the volume of the spill, the duration of the release, and the viscosity
and density of the crude oil.
The size of potential spills and the type of oil that would likely be released from the Keystone XL
pipeline have been issues of concern to opponents of the project. In its July 16, 2010, comments
on the draft EIS for the Keystone XL pipeline, EPA expressed particular concern over the
potential adverse impacts to surface and ground water from pipeline leaks or spills. That concern
stemmed from two areas—the toxicity of chemical diluents that may be used to allow bitumen to
be transported by pipeline and the lack of risk assessment for potential “serious or significant
spills,” including an evaluation of spill response procedures in the wake of such a spill.
Concerns reflected in EPA’s letter were realized 10 days later when the Enbridge Energy Partners’
Alberta Pipeline ruptured near Marshall, MI. The resulting spill released dilbit crude into a
tributary creek of the Kalamazoo River and traveled approximately 40 miles downstream in the
Kalamazoo River. Initially estimated by Enbridge as a release of approximately 800,000 gallons

2011, p. ES-9.

of crude, EPA subsequently estimated that over 1.1 million gallons were released. The spill
resulted in over 220 areas of moderate-to-heavy contamination, including over 200 acres of
submerged oil on the river bottom and over 300 solidified oil deposits.115 Enbridge estimates that
cleanup will cost approximately $700 million.
The Enbridge spill highlighted several issues of concern among environmental groups and
communities along the pipeline route—in particular, the nature of the dilbit crude likely carried
by the Keystone XL pipeline. The dilbit crude in the Enbridge spill had been diluted with benzene
and other hazardous constituents. Following the spill, high levels of benzene in the air prompted
the issuance of voluntary evacuation of residents in the area. Concern over the presence of
similarly toxic constituents, particularly the degree to which the level of toxic constituents may be
unknown at the time of a release, has been an ongoing concern among environmental and
community groups.
The Enbridge spill was considered a “very large spill” and not necessarily one that would likely
occur along the Keystone XL pipeline route. However, in its first year of operation,
TransCanada’s Keystone pipeline experienced 14 spills. Although mostly minor spills, one spill at
the Ludden, ND, pump station resulted in the release of 21,000 gallons of oil. Like the Enbridge
release, that release was first reported by local citizens, not as a result of the Keystone’s release
detection equipment. These incidents have made pipeline opponents concerned that, absent a
witness to a spill, a leak in a remote area could potentially go undetected for a long period.
Also as illustrated in the aftermath of the Enbridge spill, cleanup of bitumen crude presents
certain challenges. Dilbit is a relatively heavy crude oil mixture compared to other crude oils. In
general, heavier oils are more persistent and present greater technical challenges in removal after
a spill compared to lighter oils. Almost two years after the Enbridge spill, cleanup efforts
continue. Since the spill, public access to 39 miles of the river system was banned to protect
public health and safety. The first three-mile segment of river reopened to the public on April 27,
2012. Elements of the cleanup are expected to last until 2015.
Regardless of design, construction, and safety measures, the Keystone XL pipeline will likely
have some number of spills over the course of its operating life. The unique oil spill response
efforts necessary for dilbit crude make an accurate assessment of potential oil spill risk
particularly relevant when addressing concerns expressed by opponents to the Keystone XL
pipeline. The need for more conclusive analysis of potential risks associated with the transport of
dilbit crude was addressed, in part, in the Pipeline Safety, Regulatory Certainty, and Job Creation
Act of 2011 (P.L. 112-90, enacted January 16, 2012). In particular, under Section 16, “Study of
transportation of diluted bitumen,” the Secretary of Transportation is required to conduct an
analysis to determine whether there is any increased risk of a release for pipeline facilities
transporting diluted bitumen. In response to that directive, the PHMSA contracted with the
National Academy of Sciences to conduct a full and independent study of this topic. For further
analysis of environmental issues associated with the Keystone XL project, see CRS Report
R42611, Oil Sands and the Keystone XL Pipeline: Background and Selected Environmental

Keystone XL Pipeline Project: Key Issues

Appendix A. Presidential Permitting Authority116
The executive branch has exercised permitting authority over the construction and operation of
“pipelines, conveyor belts, and similar facilities for the exportation or importation of petroleum,
petroleum products” and other products at least since the promulgation of Executive Order 11423
in 1968.117 Executive Order 13337 amended this authority and the procedures associated with the
review, but did not substantially alter the exercise of authority or the delegation to the Secretary
of State in E.O. 11423.118 However, the source of the executive branch’s permitting authority is
not entirely clear from the text of these Executive Orders. Generally, powers exercised by the
executive branch are authorized by legislation or are inherent presidential powers based in the
Constitution. E.O. 11423 makes no mention of any authority, and E.O. 13337 refers only to the
“Constitution and the Laws of the United States of America, including Section 301 of title 3,
United States Code.”119 Section 301 simply provides that the President is empowered to delegate
authority to the head of any department or agency of the executive branch.
The legitimacy of this permitting authority has been addressed by federal courts. In Sisseton v.
United States Department of State
, the plaintiff Tribes filed suit and asked the court to suspend or
revoke the Presidential Permit issued under E.O. 13337 for the TransCanada Keystone
Pipeline.120 The U.S. District Court for the District of South Dakota found that the plaintiffs
lacked standing because they would be unable to prove their injury could be redressed by a
favorable decision.121 The court determined that even if the plaintiff’s injury could be redressed,
“the President would be free to disregard the court’s judgment,” as the case concerned the
President’s “inherent Constitutional authority to conduct foreign policy,” as opposed to statutory
authority granted to the President by Congress.122
The court further found that even if the Tribes had standing, the issuance of the Presidential
Permit was a presidential action, not an agency action subject to judicial review under the
Administrative Procedure Act (APA).123 The court stated that the authority to regulate the cross-
border pipeline lies with either Congress or the President.124 The court found that “Congress has
failed to create a federal regulatory scheme for the construction of oil pipelines, and has delegated
this authority to the states. Therefore, the President has the sole authority to allow oil pipeline
border crossings under his inherent constitutional authority to conduct foreign affairs.”125 The

President could delegate his permitting authority to the U.S. Department of State, but delegation
did not transform the permit’s issuance into an agency action reviewable under the APA.126
In Sierra Club v. Clinton,127 the plaintiff Sierra Club challenged the Secretary of State’s decision
to issue a Presidential Permit authorizing the Alberta Clipper pipeline. Among the plaintiff’s
claims was an allegation that issuance of the permit was unconstitutional because the President
had no authority to issue the permits referenced in E.O. 13337 (in this case, for the importation of
crude oil from Canada via pipeline).128 The defendant responded that the authority to issue
Presidential Permits for these border-crossing facilities “does not derive from a delegation of
congressional authority ... but rather from the President’s constitutional authority over foreign
affairs and his authority as Commander in Chief.”129 The U.S. District Court for the District of
Minnesota agreed, noting that the defendant’s assertion regarding the source of the President’s
authority has been “well recognized” in a series of Attorney General opinions, as well as a 2009
judicial opinion.130 The court also noted that these permits had been issued many times before and
that “Congress has not attempted to exercise any exclusive authority over the permitting process.
Congress’s inaction suggests that Congress has accepted the authority of the President to issue
cross-border permits.”131 Based on the historical recognition of the President’s authority to issue
these permits and Congress’s implied approval through inaction, the court found the Presidential
Permit requirement for border facilities constitutional.

and Natural Resources Defense Council (NRDC) v. U.S. Department of State, 658 F.Supp.2d 105, 109 (D.D.C. 2009)).
The court in NRDC held that the State Department’s issuance of a presidential permit under Executive Order 13337
was not subject to judicial review under the Administrative Procedure Act for abuse of discretion because “the issuance
of presidential permits is ultimately a presidential action.” 658 F. Supp. 2d at 109, 111-12. The court said that to allow

Keystone XL Pipeline Project: Key Issues

Appendix B. Milestones in the Initial NEPA Process
The NEPA process for TransCanada’s 2008 Presidential Permit application for the Keystone XL
pipeline project included several significant milestones (summarized in Table 1). These events,
and resulting documents, will likely have varying degrees of influence over TransCanada’s 2012
permit application.
Draft EIS issued
The State Department released its draft EIS for the proposed Keystone XL Pipeline project for
public comment on April 16, 2010.132 The draft EIS identified TransCanada’s “preferred
alternative” for the project as well as other alternatives considered. On July 16, 2010, EPA rated
the draft EIS “Inadequate.”133 EPA found that potentially significant impacts were not evaluated
and that the additional information and analysis needed was of such importance that the draft EIS
would need to be formally revised and again made available for public review. Additional
criticism of the State Department’s implementation of the NEPA process followed an October 21,
2010, statement by Secretary Clinton that, while analysis of the project was not complete and a
final decision had not been made, the State Department was “inclined to” approve the project.134
Critics of the project, including some Members of Congress, stated that the Secretary’s statement
appeared to prejudge its permit approval for the pipeline proposal as a foregone conclusion.135
Supplemental Draft EIS Issued
The State Department issued a supplemental draft EIS on April 15, 2011. In addition to
addressing issues associated with EPA’s inadequacy rating, the supplemental draft EIS addressed
comments received from other agencies and the public. On June 6, 2011, EPA sent a letter to the
State Department that rated the supplemental draft EIS as having “Insufficient Information” and
having “Environmental Objections” to the proposed action.136 EPA acknowledged that the State
Department had “worked diligently” to develop additional information in response to EPA’s
comments and the large number of other comments on the draft EIS. However, EPA believed that
additional analysis needed to be included in the final EIS to fully respond to its earlier comments.

132 Documents submitted for the initial 2008 Presidential Permit application have now been archived by the State
Department. Documents related to that original application are available at http://keystonepipeline-xl.state.gov/archive/

that the Secretary was referring to the Keystone XL pipeline permit approval.

Keystone XL Pipeline Project: Key Issues

Among other items, EPA recommended that the State Department should do the following:
improve the analysis of the potential oil spill risks, including additional analysis of other
reasonable alternatives to the proposed pipeline route; provide additional analysis of potential oil
spill impacts, health impacts, and environmental justice concerns to communities along the
pipeline route and adjacent refineries; and improve its characterization of lifecycle greenhouse
gas emissions associated with Canadian oil sands crude.
In its June 6 letter to the State Department, EPA refers to agreements with the State Department
that certain deficiencies identified in the supplemental draft EIS would be addressed in the final
EIS. Further, in its conclusion, EPA stated that it would carefully review the final EIS to
determine if it fully reflects those agreements and if measures to mitigate adverse environmental
impacts are fully evaluated.
Final EIS Issued
On August 26, 2011, the State Department issued the final EIS for the proposed Keystone XL
Pipeline. Among other elements of the final EIS, it identified various major pipeline route
alternatives and an environmental analyses of potential impacts associated with those
alternatives.137
In October 2011, 14 Members of Congress wrote to the State Department’s Office of Inspector
General requesting an investigation of the department’s handling of the EIS and National Interest
Determination for the Keystone XL project.138 The request was prompted, in part, by press reports
suggesting bias or potential conflicts of interest in the State Department’s hiring of an outside
contractor to perform the EIS and in its communications with the pipeline’s developer,
TransCanada.139 On November 4, the Inspector General’s Office (IG) announced that, in response
to this request, it was initiating a special review “to determine to what extent the Department and
all other parties involved complied with Federal laws and regulations relating to the Keystone XL
pipeline permit process.”140 On February 9, 2012, the IG released its findings, reporting that the
State Department “did not violate its role as an unbiased oversight agency,” among other specific
findings generally supportive of the department’s Keystone XL permit review process.141
Public Review and National Interest Determination
Following the release of the Keystone XL project’s final EIS, a review period began to determine
if the proposed project was in the national interest. As part of the process for the Keystone XL
project, the State Department held public meetings in each of the six states through which the

proposed pipeline would pass and in Washington, DC.142 The meetings were intended to give
members of the public additional opportunity to voice their opinions on issues they thought
should be taken into account in determining whether granting or denying the Presidential Permit
would be in the national interest.143 During the review period, the State Department received input
from state, local, and tribal officials as well as members of the public.
After the public review period, the State Department issued a statement regarding the public
comments and its response to those comments.144 The State Department stated that it received
comments on a wide range of issues, including the Keystone XL project’s potential impact on
jobs, pipeline safety, health concerns, the societal impact of the project, and oil extraction in
Canada. Concern regarding the proposed pipeline route through the Sand Hills area of Nebraska
was identified as one of the most common issues raised. Comments regarding that pipeline route
were consistent with the environmental impacts identified in the final EIS with regard to the
unique combination of characteristics of the Sand Hills region.
To understand the concerns associated with potential environmental impacts of the construction
and operation of a pipeline that crosses the Sand Hills (also referred to as the Sandhills), an
understanding of the unique size and structure of the region is useful. It is a 19,600 square mile
sand dune formation stabilized by native grasslands that cover 95% of its surface. The surface is
highly susceptible to wind erosion if the grassland is disturbed.145 Below its surface lie hundreds
of feet of coarse sand and gravel. Essentially, the porous soil acts like a giant sponge that quickly
absorbs precipitation, allowing very little to run off. In some areas, the water table reaches the
land surface—a characteristic that creates lakes that dot the region as well as 1.3 million acres of
wetlands.
The Sand Hills sits atop the Ogallala Aquifer—one of the largest aquifer systems in the world.146
The highly porous soil of the Sand Hills make the area a significant recharge zone in the northern
region of the Ogallala Aquifer system. That is, the sandy, porous soil of the Sand Hills allows a
significant amount of surface water to enter (recharge) the aquifer system. Water from the aquifer
also accounts for a significant amount of water use—78% of the region’s public water, 83% of
irrigation water in Nebraska, and 30% of water used in the U.S. for irrigation and agriculture.
In the final EIS, the preferred pipeline route through Nebraska would have been located entirely
above the Ogallala Aquifer. Potential impacts to the Ogallala Aquifer and the Sand Hills
identified in the final EIS include potential groundwater contamination after a release (e.g., a spill
or leak from a hole or damaged portion of the pipeline) of crude oil during the construction or
operation of the proposed pipeline. Both the soil porosity and the close proximity of groundwater

143 These additional public meetings are not part of the NEPA process. Considering the strong public interest in the
pipeline proposal (both opposed and in favor), the public hearings were part of the State Department’s national interest
determination.

to the surface increase the potential that a release of oil from the pipeline could contaminate
groundwater in the region.
During the public review period, the governor of Nebraska called a special session of the
legislature to determine if siting legislation could be crafted and passed for pipeline routing in
Nebraska. Facing the prospect of new state pipeline siting regulations applicable to the Sand
Hills, together with the concern about the Keystone XL pipeline’s specific “preferred” route, the
State Department announced that it would require additional information about alternative
pipeline routes avoiding the environmentally sensitive Sand Hills area in Nebraska before moving
forward with its National Interest Determination.147 Although the State Department did not decide
that environmental issues led to a determination that the proposed project was not in the national
interest, environmental issues identified in the final EIS, and further stressed in public comments,
led to its decision to delay that determination until it gathered this information.
Although no new decision deadline was established, State Department officials suggested that it
would be “reasonable to expect that this process including a public comment period on a
supplement to the final EIS consistent with NEPA could be completed as early as the first quarter
of 2013.”148 In a prior press interview, President Obama also appeared to suggest that,
notwithstanding the delegation of Presidential Permit authority to the State Department, he would
be personally involved in the final decision on the Keystone XL Pipeline permit application.149
Directive to the President to Approve or Deny the Permit
In the wake of the State Department determination that supplemental analysis was needed,
Congress directed the President to make a determination on the Presidential permit application for
the Keystone XL pipeline. Specifically, the Temporary Payroll Tax Cut Continuation Act of 2011
(P.L. 112-78), enacted on December 23, 2011, included provisions requiring the Secretary of State
to issue a permit for the project within 60 days, unless the President publicly determined the
project to be not in the national interest.
Subsequently, the State Department, with the President’s consent, announced that it would deny
the Keystone XL permit on January 18, 2012. In its announcement the department stated that its
decision “was predicated on the fact that [P.L. 112-78] ... passed in December does not provide
sufficient time to obtain the information that we think is necessary to assess whether the project,
in its current state, is in the national interest.”150 However, the department also stated that its
decision did not preclude TransCanada from reapplying for a Presidential Permit in the future,
although such a reapplication “will trigger ... a completely new review process.”151
As a result of that denial, instead of developing a supplemental EIS incorporating analysis
applicable to a new pipeline route through Nebraska, a new Presidential permit application
process will be required. As a result, a “new” NEPA process will be required. Although much of
