Keystone XL Pipeline Project: Key Issues

Summary
TransCanada’s proposed Keystone XL Pipeline would transport oil sands crude from Canada and
crude produced in North Dakota and Montana to a market hub in Nebraska for further delivery to
Gulf Coast refineries. The proposed pipeline would consist of 875 miles of 36-inch pipe with the
capacity to transport 830,000 barrels per day. Because it would cross the Canadian-U.S. border,
construction of Keystone XL requires a Presidential Permit from the State Department. A decision
to issue or deny a Presidential Permit is based on a determination that a project would serve the
national interest, considering potential impacts on the environment, the economy, energy security,
foreign policy, and other factors. Environmental impacts are evaluated and documented in an
Environmental Impact Statement (EIS) under the National Environmental Policy Act (NEPA).
TransCanada originally applied for a Presidential Permit for the Keystone XL Pipeline in 2008.
The initial proposal included a southern segment from Oklahoma to the Gulf Coast. After a final
EIS for the original project was released in August 2011, the State Department began a 90-day
public review period to make its national interest determination. A key issue that arose during this
review was concern over environmental impacts in the Sand Hills region of Nebraska. This
concern led the Nebraska legislature to enact new state pipeline siting requirements that would
alter the pipeline route through Nebraska. In January 2012, the State Department concluded that it
would not have sufficient information to evaluate an altered pipeline route before a deadline
imposed by Congress and denied the permit. The southern segment of the original Keystone XL
proposal, now called the Gulf Coast Project, was subsequently separated from the original
proposal because it did not require a Presidential Permit. It has been approved by the relevant
states and is currently under construction.
In May 2012, TransCanada reapplied to the State Department for a Presidential Permit to build
the northern, cross-border segment of Keystone XL. The new permit application initiated a new
NEPA process. The governor of Nebraska approved a new route through the state avoiding the
Sand Hills on January 22, 2013. On March 6, 2013, notice was published in the Federal Register
that the State Department draft EIS for the reconfigured Keystone XL Project was available for
public comment until April 22, 2013. Public comments must be addressed by the State
Department before a final EIS can be issued. After that, the 90-day public review period for the
national interest determination begins.
Development of the Keystone XL Pipeline has been controversial. Proponents base their
arguments supporting the pipeline primarily on increasing the diversity of the U.S. petroleum
supply and economic benefits, especially jobs. Pipeline opposition stems in part from concern
regarding the greenhouse gas emissions associated with the development of Canadian oil sands,
continued U.S. dependency on fossil fuels, and the risk of a potential release of heavy crude. The
Energy Production and Project Delivery Act of 2013 (S. 17), the Keystone for a Secure Tomorrow
Act (H.R. 334), a bill to approve the Keystone XL Pipeline (S. 582), and the Northern Route
Approval Act (H.R. 3) would all effectively approve the Keystone XL Pipeline. The Strategic
Petroleum Supplies Act (S. 167) would suspend sales of petroleum products from the Strategic
Petroleum Reserve until the pipeline is approved. On March 22, 2013, the Senate passed an
amendment to the Fiscal 2014 Senate Budget Resolution (S.Con.Res. 8) that would provide for
the approval and construction of the Keystone XL Pipeline (S.Amdt. 494).

Keystone XL Pipeline Project: Key Issues

Introduction1
TransCanada (a Canadian company) has applied to the U.S. Department of State for a Presidential
Permit to build the Keystone XL Pipeline Project. The Keystone XL Pipeline would transport
Canadian oil sands crude extracted in Alberta, Canada, and crude produced from the Bakken
region in North Dakota and Montana to a market hub in Nebraska for further delivery to Gulf
Coast refineries. Because it would cross the Canadian-U.S. border, construction of Keystone XL
requires a Presidential Permit from the State Department. A decision to issue or deny a
Presidential Permit is based on a determination that a project would serve the national interest.
TransCanada originally applied for a Presidential Permit for the Keystone XL Pipeline in 2008.
The original proposal included a southern segment from Oklahoma to the Gulf Coast. After a
final EIS for the original project was released in August 2011, the State Department began a 90-
day public review period to make its national interest determination. One key issue that arose
during this review was concern over environmental impacts in the Sand Hills region of Nebraska.
This concern led the Nebraska legislature to enact new state pipeline siting requirements that
would alter the pipeline route through Nebraska. In January 2012, the State Department
concluded that it would not have sufficient information to evaluate an altered pipeline route
before a deadline imposed by Congress and denied the permit. TransCanada and Nebraska have
since agreed upon an alternative pipeline route avoiding the Sand Hills.2 In May 2012,
TransCanada reapplied to the State Department for a Presidential Permit to build the cross-border
segment of Keystone XL.
This report describes the Keystone XL Project, as proposed by TransCanada in its May 4, 2012,
Presidential Permit application, and the process that the State Department is obligated to complete
in processing that permit application. It also reviews selected 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 discusses the constitutional basis for the State Department’s
authority to issue a Presidential Permit, and opponents’ possible challenges to this authority.
Presidential Permit Review
Siting authority for oil pipelines generally lies with the states. However, the construction of
facilities at the U.S. border for exporting or importing petroleum or other fuels requires a
Presidential Permit issued by the Department of State. Before deciding whether to grant or deny a
Presidential Permit, the Secretary of State must determine whether a project is in the national
interest, taking account of factors such as energy security; environmental, cultural, and economic

impacts; foreign policy; and compliance with relevant federal regulations. The identification and
consideration of environmental impacts is 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.).3
Generally, a draft and final EIS would be prepared for a project. Once a final EIS is issued to
inform the national interest determination, the Secretary of State must request the views of the
Attorney General, the Secretaries of Defense, Energy, the Interior, Transportation, Homeland
Security, and Commerce, and the U.S. Environmental Protection Agency. The Secretary of State
may also consult with such state, tribal, and local government officials and foreign governments,
as the Secretary deems appropriate, with respect to each application. To expedite the process, the
Secretary is required to allow for agency and public comment for a period not to exceed 90 days
from the date of the request public input process begins. The details of the State Department’s
application review process for Keystone XL are discussed later in this report.
Keystone XL Permit Applications
For the 2008 Keystone XL permit application, the NEPA compliance process involved
preparation of a draft, supplemental draft, and final EIS. During that process, a wide range of
environmental issues were identified that drew support for and opposition to the Keystone XL
Pipeline. Once the NEPA process was largely complete (a final EIS had been issued) and the
national interest determination process was underway, issues arose that made it clear that a
supplemental final EIS would have to be prepared. In particular, the State Department determined
that concern regarding pipeline construction across the Sand Hills region in Nebraska would
require the consideration of an alternative pipeline route. In response to action taken by
Nebraska’s governor and legislature, on November 10, 2011, the State Department announced
that it needed to undertake an in-depth assessment of alternative pipeline routes that would avoid
the Sand Hills.4 That assessment would be necessary before it could complete its national interest
determination. Subsequently, on November 14, 2011, TransCanada announced an agreement with
the Nebraska Department of Environmental Quality (DEQ) to identify a pipeline route that would
avoid the Sand Hills.
After the State Department’s announcement of a delay in the permit review, Congress acted to
expedite a permit decision on the Keystone XL Pipeline. 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

3 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 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.

insufficient time under the 60-day deadline to obtain all the necessary information to assess the
reconfigured project.5
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
originally proposed as part of the Keystone XL Project. The construction and operation of the
Gulf Cost Project did not require a Presidential Permit since that segment of the pipeline would
be located entirely within the United States. 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.6
On May 4, 2012, the State Department received a new application from TransCanada for a
reconfigured Keystone XL Project running from the Canadian border to an existing pipeline and
oil market hub in Steele City, NE.7 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.8
The governor of Nebraska approved a new route through the state on January 22, 2013.9 On
March 1, 2013, the State Department issued a draft EIS for the modified Keystone XL Project.10
The reconfigured project would be 875 miles long and cross three states—Montana, South
Dakota, and Nebraska.
Past Congressional Actions
Since it was initially proposed in 2008, many Members of Congress have expressed support for
the Keystone XL pipeline’s potential energy security and economic benefits, while many others
have expressed reservations about its potential environmental impacts.11 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.

Keystone XL Pipeline Project: Key Issues

In the 112th Congress, 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) 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) and the Middle Class Tax Relief and Job Creation Act of 2011 (H.R.
3630) contained similar provisions for issuing a Presidential Permit within 60 days of enactment.
All of these proposals were mooted by the State Department’s initial denial of the permit.
Additional legislative proposals followed TransCanada’s second permit application. The North
American Energy Access Act (H.R. 3548) would have transferred the permitting authority over
the Keystone XL pipeline project from the State Department to the Federal Energy Regulatory
Commission, 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) would have immediately
approved the original permit application filed by TransCanada in 2008. The Grow America Act of
2012 (S. 2199), the EXPAND Act (H.R. 4301), S. 2041 (a bill to approve the Keystone XL
pipeline), and the Energizing America through Employment Act (H.R. 4000), would have
similarly approved the original permit upon passage. All six bills included provisions allowing for
later alteration of the pipeline route in Nebraska. A House bill (H.R. 6164) and The Domestic
Energy and Jobs Act (S. 3445) both would have eliminated 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) contained the same language.12
H.R. 3900 sought 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 and H.R. 4211 would have suspended sales of petroleum products from the
Strategic Petroleum Reserve until issuance of a Presidential Permit for the Keystone XL project
application filed in 2008.
Congressional Actions in the 113th Congress
In the 113th Congress, several legislative proposals from the prior Congress have been
reintroduced. The Energy Production and Project Delivery Act of 2013 (S. 17) would eliminate
the Presidential Permit requirement for the reconfigured Keystone XL pipeline. The Keystone for
a Secure Tomorrow Act (H.R. 334) and a Senate bill to approve the Keystone XL Pipeline (S.
582) would directly approve the Keystone XL Pipeline under the authority of Congress to
regulate foreign commerce. The Northern Route Approval Act (H.R. 3) would eliminate the
Presidential Permit requirement for Keystone XL and require issuance of permits for water
crossings by the Army Corps of Engineers within 90 days of an application, among other
provisions. On March 22, 2013, the Senate passed an amendment to the Fiscal 2014 Senate
Budget Resolution (S.Con.Res. 8) that would provide for the approval and construction of the
Keystone XL Pipeline (S.Amdt. 494). Congressional debate continues.

12 S.Amdt. 2789 would have amended the Veterans Jobs Corps Act of 2012 (S. 3429).

Keystone XL Pipeline Project: Key Issues

Description of the Keystone Pipeline System
In 2005, TransCanada announced its plan to address expected increases in Western Canadian
Sedimentary Basin 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 distinct phases—the Keystone Pipeline
(complete and in service) and Keystone XL Pipeline.
The Keystone and Keystone XL Pipeline Systems
The Keystone Pipeline was completed in two segments—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, Illinois. 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 Kansas border) to existing crude oil terminals and tanks farms
in Cushing, OK. The Cushing Extension has been in service since February 2011.
The Keystone XL pipeline system is also being proposed in two segments, as follows:
The Gulf Coast Project, 485 miles of 36-inch pipeline and associated facilities
linking the Cushing, OK, 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 Project, 875 miles of 36-inch pipeline and associated
facilities linking Hardisty, Alberta to Steele City, NE. This segment also includes
the Bakken Marketlink in Baker, MT—receipt facilities that can transport crude
oil from the Williston Basin producing region for delivery to Steele City then
Gulf Coast refineries. Of the Keystone Pipeline’s 830,000 bpd capacity, 100,000
bpd has been set aside to transport Bakken crude oil.
The Keystone Pipeline currently has the capacity to deliver up to 590,000 bpd of Canadian crude
oil to U.S. refineries and export terminals. The Keystone XL Pipeline system (the northern and
southern segments) would have a capacity of 830,000 bpd. As a result, the entire Keystone
Pipeline System may ultimately have the capacity to deliver up to 1.3 million bpd of crude oil.
The existing Keystone Pipeline and proposed expansions are illustrated in Figure 1. The
proposed Keystone XL Project and associated projects are illustrated in Figure 2.

Marketlink for Bakken Oil Production
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.15 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.16 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, in
addition to more economical transport by pipeline. (For more analysis, see CRS Report R42032,
The Bakken Formation: Leading Unconventional Oil Development, by Michael Ratner et al.)
The proposed Keystone XL Project would include receipt facilities to transport crude produced
from the 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, Montana, to Cushing, OK, via the proposed Keystone XL pipeline and from Cushing to
delivery points in Texas, via the proposed Gulf Coast Project.17 Keystone Marketlink18 estimates
that the project will cost $140 million and have the ability to deliver approximately 100,000 bpd
of crude oil to the proposed Keystone XL pipeline.19 Keystone Marketlink currently has firm,
long term contracts to transport 65,000 bpd of the 100,000 bpd.20
The Bakken contracts improve the economics for Keystone XL Pipeline, raising the amount of oil
slated to flow through the pipeline.21 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.22 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.”23 Rail transport capacity
is also expanding.24
Presidential Permit Application Requirements
Ordinarily, federal agencies have no authority to site oil pipelines, even interstate pipelines.25 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.

17 The Bakken Marketlink project is described in the August 2011 final EIS for the 2008 Presidential Permit application
in Section 2.5.3, available at http://keystonepipeline-xl.state.gov/documents/organization/182012.pdf.

Keystone XL Pipeline Project: Key Issues

Executive Order 13337 delegates to the Secretary of State the President’s authority to receive
applications for Presidential Permits.26 Issuance of a Presidential Permit depends on a State
Department determination that the project would serve the “national interest.” The term is not
defined in the Executive Orders or elsewhere. Regarding its interpretation of the term, the State
Department has asserted that, consistent with the President’s broad discretion in the conduct of
foreign affairs, it has significant discretion in deciding the factors it will examine in making a
national interest determination.27 The State Department will not necessarily evaluate the same
factors for each project seeking a permit. However, for the 2008 Keystone XL Project, the State
Department identified the following as key factors it considered when making determinations for
previous applications for pipeline permits:
• 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;
• 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.28
The State Department has broad discretion in determining what factors it will examine to inform
its national interest determination and, ultimately, whether a proposed project is in the national
interest. However, the State Department is required to consult with and seek the views of the
Secretaries of Defense, the Interior, Commerce, Transportation, Energy, and Homeland Security;
the Attorney General; and the Administrator of the Environmental Protection Agency. The
Department is also required to solicit input from affected local, tribal, and state agencies and to
invite public comment in arriving at its determination.

Keystone XL Pipeline Project: Key Issues

The Consideration of Environmental Impacts Under NEPA
Apart from the potential to consider environmental impacts when making a national interest
determination, pursuant to the National Environmental Policy Act (NEPA, 42 U.S.C. §4321 et
seq.), the State Department would be obligated to consider the environmental impacts of granting
or denying a Presidential Permit.29 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 before final agency decisions are made, for
every major federal action that may have a significant impact upon the environment, an
Environmental Impact Statement (EIS) must be prepared.30 With respect to the 2012 Presidential
Permit application submitted by TransCanada, the State Department concluded that approval of a
permit for the proposed construction, connection, operation, and maintenance of the pipeline and
its associated facilities at the United States border could result in significant environmental
impacts and, hence, requires the preparation of an EIS.31
This report provides an overview of the NEPA compliance process relevant to approval of a
Presidential Permit. It also summarizes milestones in the NEPA compliance process, undertaken
for both the 2008 permit application and the 2012 application that is currently being processed by
the State Department.
Overview of the NEPA Process Relevant to Presidential Permit Approval
Preparing an EIS is the responsibility of a designated “lead agency,” in this case, the State
Department. In developing an EIS for a private party applicant (TransCanada) the State
Department may use a third-party contractor. Consistent with regulations implementing NEPA,
such a contractor is one that is selected by and works under the direction of the State Department,
but is being paid by the applicant.32
An EIS is generally prepared in two stages—resulting in a draft and final EIS. 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.33 Accordingly, the State Department EIS must

29 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.

To Conduct Scoping and To Initiate Consultation Under Section 106 of the National Historic Preservation Act for the

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

demonstrate that it has identified and considered potential environmental impacts of the entire
pipeline project (including the construction, operation, and maintenance of the pipeline and its
associated facilities), not just the facilities at the border crossing.
In preparing the EIS, the State Department 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.34 Cooperating agencies for the Keystone XL
Project include 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 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.35 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, in this case the Department of State,
would then be required to respond to EPA’s rating, as appropriate.
As the NEPA compliance process for TransCanada’s permit application moves forward, it is
helpful 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).
Milestones in the NEPA Process for the Keystone XL Pipeline Project
For TransCanada’s 2008 Presidential Permit application, a draft, supplemental draft, and final EIS
was prepared. Those documents identified environmental impacts associated with the Keystone
XL Pipeline—a proposed pipeline route that would have extended from the Canadian border in

Keystone XL Pipeline Project: Key Issues

Phillips County, MT, to Steele City, NE, and construction of a pipeline from Cushing, OK, to the
Gulf Coast of Texas. For the 2012 permit application, the EIS evaluates potential impacts
associated with the new route from Montana to Steele City, NE, that avoids the Nebraska Sand
Hills, and excludes the proposed Gulf Coast Project.
On March 1, 2013, the State Department released the draft EIS for the proposed Keystone XL
Project,36 as a supplement to the final EIS prepared for the 2008 Presidential Permit application
(released in August 2011).37 According to the State Department, the draft EIA includes a
“comprehensive review of the new route in Nebraska as well as any significant new
circumstances or information that is now available on the largely unchanged route in Montana
and South Dakota. It also expands and updates information that had been included in the 2011
Final Environmental Impact Statement that was prepared for the previous Keystone XL
application.”38
On March 8, a notice of availability for the draft EIS was published in the Federal Register.39 For
a minimum of 45 days after publishing that notice, the State Department must receive public
comments (including local, state, tribal, or federal agency comments) on the draft. The public
comment period ends on April 22, 2013. After receiving agency and public comments on the draft
EIS, and possibly modifying the EIS to address those comments, the State Department may issue
a final EIS. The time it takes between the issuance of the draft and the final EIS would depend on
a range of factors, including the scope and the nature of the comments—particularly comments
from cooperating agencies, such as EPA.
Major milestones in the NEPA process, for both the 2008 and 2012 Presidential Permit
applications are listed in Table 1, below (for detail on milestones associated with the 2008 permit
application, see Appendix B).

36 See U.S. Department of State, “New Keystone XL Pipeline Application” webpage at http://www.keystonepipeline-
xl.state.gov/.
37 The State Department refers to the EIS released in 2013 as a “Draft Supplemental” EIS. This reference apparently
reflects the fact that the 2013 draft EIS draws largely from (or supplements) documentation and analysis included in the
final EIS issued for the Keystone XL Project in 2011. However, for purposes of NEPA compliance, the submission of a
new permit application in May 2012 started the NEPA process anew. While it may draw from the 2011 final EIS, the
2013 draft EIS is a new NEPA document—not a supplement to an EIS prepared for a different, albeit similar,
Presidential Permit application.

Source: Congressional Research Service, based on a review of events during, and affecting, the NEPA process
conducted for the 2008 and 2012 Presidential permit applications for the Keystone XL Project.
Had the State Department modified its final EIS for the 2008 Presidential Permit application and
continued 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 final 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 is required to begin a new NEPA process and, eventually, determine whether
that project would serve the national interest.40
NEPA and the National Interest Determination
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 those necessary to inform its national interest determination. 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.41 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

Keystone XL Pipeline Project: Key Issues

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.
Overview of the Process for the 2008 Keystone XL Pipeline Project
During the 90-day public review period for the 2008 Presidential Permit application, the State
Department held public meetings in each of the six states through which the proposed pipeline
would pass and in Washington, DC.42 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.43 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.44 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.45

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.”46
The State Department has subsequently stated that it did not anticipate concluding the federal
review process before the end the first quarter of 2013.47 In a 2011 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.48
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
information necessary to assess whether the project, in its current state, is in the national
interest.”49 Milestones in the State Department process to make its national interest determination
for the 2008 permit application are summarized in Table 2.

State Siting and Additional Environmental Requirements
As noted 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
Congressional Research Service
17

Keystone XL Pipeline Project: Key Issues

issued the permit on April 25, 2010.50 Montana requires a certificate from the state’s Department
of Environmental Quality.51
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.52 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 and one that outlines
procedures for siting any future oil pipeline in Nebraska.53 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 2013 draft EIS for the Keystone XL Project lists
major permits, licenses, approvals, and consultation requirements for the proposed project that
would be required by federal, state, and local agencies prior to implementation of the project.54
Following are selected requirements included on that list:
• 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.

Keystone XL Pipeline Project: Key Issues

• 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 took to complete the NEPA process was a focus of attention for the 2008 Presidential
Permit application. However, for past pipeline projects, obtaining all required local, state, tribal,
and federal permits, approvals, and licenses took 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.
Legislative Efforts to Change Permitting Authority
In light of the State Department’s denial of the 2008 permit application for the Keystone XL
Project, some in Congress have sought alternative means to support development of the pipeline.
There were a number of legislative proposals in the 112th Congress to change the federal
permitting authority for the pipeline. H.R. 3548 would have transferred the permitting authority
over the Keystone XL 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.55 Other proposals, such as H.R. 3811 and S. 3445, would have directly shifted
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.56
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

2012, also contained these provisions, but they were subsequently dropped from the bill in conference committee with
the Senate.

concerns.57 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.58 That is, the final agency action reflected in an
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 Project, including Canadian agencies and U.S. and Canadian
petroleum industry stakeholders, base their arguments supporting the pipeline primarily on
increasing the security and 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.59 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.
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

58 While the APA’s definition of “agency” does not specifically exclude or include the president, the Supreme Court
has held that exercises of presidential authority are not subject to judicial review because the president is not an agency
(Dalton v. Specter, 511 U.S. 462, 470 (1994)). The Court has also held that the APA does not apply to the president
based on separation of powers principles (Franklin v. Massachusetts, 505 U.S. 788, 800-01 (1992)).

Keystone XL Pipeline Project: Key Issues

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.60 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.61 Depending upon the circumstances, however, such
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.62
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.63
Canadian Oil Imports in the Overall U.S. Supply Context64
Gross U.S. imports of crude oil and petroleum products averaged 11.4 million bpd (Mbpd) in
2011.65 U.S. oil exports averaged 2.9 Mbpd (almost entirely petroleum products), leaving net
imports at 8.4 Mbpd.66 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.67
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

60 TransCanada Keystone Pipeline, L.P., September 19, 2008, pp. 6-8.
61 On February 7, 2012, the House Energy and Committee rejected an amendment to H.R. 3548 offered by
Representative Edward Markey containing similar export restrictions.
62 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.

66 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.

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.68
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.69 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).70 Some expect Canadian oil
production to grow by nearly 2 Mbpd by 2025 due to increased output from the oil sands.71

Keystone XL Pipeline Project: Key Issues

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
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.72
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.73 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,74 especially if the new Canadian crudes will be used in large amounts.75
There are 58 refineries in the Gulf Coast region (potentially served by the proposed Gulf Coast
Project) that could process heavy crude oil similar in composition to the oil that Keystone XL
pipeline would carry.76
Oil production from the oil sands is increasing, as is production from the Bakken and other areas
of the U.S. Midwest.77 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.78
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

72 CAPP, 2011, p. 7.
73 CAPP, 2011, p. 13. According to CAPP, refineries adding capacity to process more heavy oil in the Midwest include
those in Roxana, IL; Whiting, IN, and Detroit, MI.

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 Coast 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.
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.79 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.80 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 2019.81 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.

Keystone XL Pipeline Project: Key Issues

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,82 sold its share of
Seaway to Enbridge. Enbridge and Seaway shareholder Enterprise Products Partners L.P. reversed
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 began running southward at an initial capacity of
150,000 bpd in 2012, with capacity expected to increase to 400,000 bpd in 2013. The reversal and
expansion are 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).83
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.84 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.85 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).86 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.
In February 2013, Enbridge also announced a proposal to convert segments of existing natural
gas pipeline owned by Trunkline Gas Company to carry crude oil from western Canada and North
Dakota to refineries in the eastern Gulf of Mexico. The pipeline conversion could potentially
carry up to 660,000 bpd from the market hub at Patoka, IL, more than 700 miles to St. James,
LA.87

Rail Transportation
While the oil industry has been making substantial investments in pipeline capacity to relieve
transportation bottlenecks for Canadian crudes, there has also been a substantial increase in oil
transportation from the region by rail. As the State Department’s 2013 DEIS for the Keystone XL
project states:
In the past 2 years, there has been exponential growth in the use of rail to transport crude oil
throughout North America, primarily originating from the Bakken in North Dakota and
Montana, but also increasingly utilized in other production areas, including the [Western
Canadian Sedimentary Basin]. Because of the flexibility of rail delivery points, once loaded
onto trains the crude oil could be delivered to refineries, terminals, and/or port facilities
throughout North America, including the Gulf Coast area.88
Consistent with this view, both Canadian National Railway and Canadian Pacific Railway
reportedly have long been pursuing a “pipeline on rails” business strategy, including new track
investments, to move Canadian crudes to new markets throughout North America.89 While the
potential volumes associated with rail transportation of crude would likely be lower than pipeline

volumes, they could still be significant. Increasing cross-border movements of crude oil by rail
does not require State Department approval, so such an approach seeks to avoid regulatory
delays. As rail volumes have increased, however, some policymakers have expressed concern
about the potential safety of crude transport by rail compared to pipelines.90
Canadian Oil to East and West Coast 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,
with a small amount going to China and other Asian countries.91 Proposals for additional east and
westbound capacity include the following.
• 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.92 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.93 There is some opposition to
the project, including from groups concerned about additional tanker traffic near
Vancouver and potential oil spill risks.94
• 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.95 However, Northern Gateway faces opposition from groups including
some First Nations communities and environmental groups.96
• 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.97 Enbridge is also interested in expanding eastbound capacity

by reversing its Line 9 Pipeline.98 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.99 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.100
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.101 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.102
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.”103 A 2009 report from the Canadian Energy
Research Institute (CERI) commissioned by the American Petroleum Institute similarly
concludes that

Keystone XL Pipeline Project: Key Issues

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 2025.104
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.105 With the separation of the Gulf Coast Project from the
northern segment of the original proposal, the potential economic impact of the reconfigured
Keystone XL project has clearly changed. 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
land, and impacts on wildlife and water quality.106 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.107 Large amounts of
water and natural gas are also required (for heating) during the extraction process.108 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.109 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.110

Keystone XL Pipeline Project: Key Issues

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.111 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.”112 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.113 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.114 For further analysis of greenhouse gas emissions associated with the
Canadian oil sands, see CRS Report R42537, Canadian Oil Sands: Life-Cycle Assessments of
Greenhouse Gas Emissions
, by Richard K. Lattanzio.
Private Land Use and Oil Spill Impacts
For the proposed Keystone XL Project, approximately 88% of the land affected by pipeline
construction and operation would be privately owned, with the remaining 12% primarily state and
federal land.115 Private land uses along the proposed pipeline routes are 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 release, leak, or spill of oil. A
release is a loss of integrity of a pipeline (from the mainline or other components); a leak is a
release over time; and a spill is the liquid volume of a leak that escapes any containment system
and enters the environment.116 In estimating potential environmental impacts, several factors will

Keystone XL Pipeline Project: Key Issues

be important—including the size and location of the release, leak, or spill, and how quickly it is
remediated.
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 Project, 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
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.117 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. A March 29, 2013, release of oil sands crude from an Exxon Mobil pipeline
in Mayflower, AR, has continued to draw attention to the risk of potential spills from crude oil
pipelines.118 These incidents have made pipeline opponents concerned that such spills may be

significant and 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, which is not
yet completed. 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 Issues
, coordinated by Jonathan L. Ramseur.
Issues with the Original Pipeline Route Across the Sand Hills
In the process of examining factors necessary to determine whether the Presidential Permit for the
original Keystone XL Project 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. New pipeline routes through Nebraska, identified
in the 2013 draft EIS, reflect the work between TransCanada and Nebraska DEQ.
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.119 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

Hills at http://www.fws.gov/mountain-prairie/pfw/ne/ne4.htm.

Keystone XL Pipeline Project: Key Issues

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.120
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.121
On January 13, 2013, the Governor of Nebraska approved a proposed reroute of the Keystone XL
pipeline through Nebraska.122 The new route alternatives proposed for the Nebraska section of the
Keystone XL pipeline avoids the Sand Hills and certain areas nearby with similar soil properties.

120 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.
121 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.

Keystone XL Pipeline Project: Key Issues

Appendix A. Presidential Permitting Authority123
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 1968.124 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. 11423.125 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.”126 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.127 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.128 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.129
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).130 The court stated that the authority to regulate the cross-
border pipeline lies with either Congress or the President.131 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.”132 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.133
In Sierra Club v. Clinton,134 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).135 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.”136 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.137 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.”138 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. Details of the Initial NEPA Review
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, 2010.139 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.”140 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.141
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.142
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.143 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.

139 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/

statement by Secretary Clinton was actually made in response to a question about the Alberta Clipper pipeline project
which received a Presidential Permit from the State Department in 2009; a State Department spokesman later clarified
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.144
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.145 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.146 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.”147 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.148
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.149 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.150 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.151 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.
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
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.152 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.”153 In a prior press interview, President Obama also appeared to suggest that,

Meetings Set,” August 26, 2011, http://www.state.gov/r/pa/prs/ps/2011/08/171082.htm.
150 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.

Keystone XL Pipeline Project: Key Issues

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.154
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.”155 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.”156
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
the analysis and documentation will likely be the same, issuance of a draft and final EIS, and
corresponding public and agency comment periods, will be required.
