Keystone XL Pipeline Project: Key Issues

Summary
Canadian pipeline company TransCanada has filed an application with the U.S. Department of
State to build the Keystone XL pipeline, which would transport crude oil from the oil sands
region of Alberta, Canada, to refineries in the United States. Keystone XL would have the
capacity to transport 830,000 barrels per day, delivering crude oil to the market hub at Cushing,
OK, and further to points in Texas. The project is expected to cost more than $7.0 billion, of
which at least $5.4 billion would be spent on the U.S. portion. TransCanada is planning to build a
short additional pipeline so that oil from the Bakken formation in Montana and North Dakota can
also be carried on the Keystone XL pipeline.
As a facility connecting the United States with a foreign country, Keystone XL requires a
Presidential Permit from the State Department. Issuance of a permit is dependant upon a finding
that the project would serve the national interest. That finding is based, in part, on the
environmental impacts of the project as determined in an environmental impact statement (EIS)
prepared pursuant to the National Environmental Policy Act (NEPA). A draft EIS issued in April
2010 was rated “inadequate” by the U.S. Environmental Protect Agency (EPA).
To respond to comments from EPA, as well as the public and other agencies, the State
Department issued a supplement draft EIS in April 2011. EPA found the supplement draft
included insufficient information to determine environmental impacts and recommended
additional data and analysis to be included in the final EIS. Once a final EIS is issued, the State
Department plans to hold six public hearings to gather additional comments on whether
authorization of a Presidential Permit for Keystone XL would be in the national interest. The
State Department expects to make that decision before the end of 2011.
Opponents to the Keystone XL pipeline project, primarily environmental groups and affected
communities along the route, object to the project principally on the grounds that it supports
“dirty” Canadian oil sands development, that a potential spill could pose a risk to groundwater,
that alternative pipeline routes avoiding the Ogallala Aquifer have not been fully considered, and
that it promotes continued U.S. dependency on fossil fuels. Arguments criticizing the greenhouse
gas emissions of oil sands production, generally, are based to some degree on the assumption that
limiting pipeline capacity to U.S. markets may limit output from Canada’s oil sands.
Proponents of the Keystone XL pipeline, including Canadian agencies and petroleum industry
stakeholders, point to energy security and economic benefits, such as job creation. Some contend
that the Keystone XL project would secure growing Canadian oil supplies for the U.S. market,
which could offset imports from less dependable foreign sources. They also claim that if oil sands
output cannot flow to the United States, infrastructure to export it to Asia will likely develop.
International pipeline projects like Keystone XL are not subject to the direct authority of
Congress, but numerous Members of Congress have expressed support for, or opposition to, the
pipeline proposal because of its potential environmental, energy security, and economic impacts.
Congress may have an oversight role stemming from federal environmental statutes that govern
the pipeline’s application review process. The North American-Made Energy Security Act (H.R.
1938) would direct the President to issue a final order granting or denying the Presidential Permit
for the Keystone XL pipeline by November 1, 2011. Whatever the State Department’s decision,
legal challenges appear likely.

Keystone XL Pipeline Project: Key Issues

Introduction
In September 2008, TransCanada (a Canadian company) applied to the U.S. Department of State
for a permit to cross the U.S.-Canada international border with the Keystone XL pipeline project.
If constructed, the pipeline would carry crude oil produced from the oil sands region of Alberta,
Canada, to U.S. Gulf Coast refineries. Because the pipeline would connect the United States with
a foreign country, it requires a Presidential Permit issued by the State Department. Members of
Congress have expressed support for the proposed pipeline’s potential energy security and
economic benefits while others have expressed reservations about its potential environmental
impacts.1 Though Congress has 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. The North American-Made Energy Security Act (H.R. 1938) would
direct the President to issue a final order granting or denying the Presidential Permit for the
Keystone XL pipeline by November 1, 2011 (§ 3).
This report describes the Keystone XL pipeline proposal and the process required for federal
approval. It summarizes key arguments for and against the pipeline put forth by the pipeline’s
developers, federal agencies, environmental groups, and other stakeholders. Finally, the report
reviews the constitutional basis for the State Department’s authority to issue a Presidential Permit,
and opponents’ possible challenges to this authority.
Pipeline Description and Status
The U.S. portion of the Keystone XL pipeline project, as proposed, would pass through Montana,
South Dakota, Nebraska, Oklahoma, and Texas (Figure 1). The pipeline would consist of
approximately 1,380 miles of 36-inch-diameter pipe and have the capacity to transport 830,000
barrels per day (bpd) of crude oil to the United States, delivering up to roughly 200,000 bpd to an
existing oil terminal in Oklahoma with the remainder sent further to points in Texas.2

pumping capacity. The Keystone XL project had applied to the Pipeline Hazardous Materials Safety Administration to
operate at slightly higher pressure than permitted in standard regulations, which would have enabled a 900,000 bpd
capacity, but it withdrew its applications for such a Special Permit in August, 2010.

Note: Figure 1 shows the developer’s “preferred alternative” for the
Keystone XL pipeline route according to Presidential Permit application
documents. For discussion of alternative routes, see the State Department
EIS discussed below.
The Keystone XL project is expected to cost more than $7.0 billion, with the U.S. portion
accounting for at least $5.4 billion of that total.3 Current cost estimates include cost increases
since the project’s initial permit application was filed reportedly due to currency swings, changing
regulatory requirements, and permitting delays.4 The Keystone XL pipeline would be an
extension of TransCanada’s existing Keystone pipeline, which links the Alberta oil sands to
refineries in Illinois and Oklahoma (Figure 1). The Keystone pipeline received State Department
approval on March 17, 2008, and began commercial operation in June 2010.
Keystone XL Extension to Bakken Oil Production
The U.S. portion of the Bakken formation is an unconventional oil resource that underlies parts of
North Dakota and Montana.5 It currently produces around 350,000 bpd, much of which is

currently taken away by rail and truck, rather than by pipeline.6 In part, this is because
infrastructure has not kept up with rapid production growth in the Bakken region in recent years.
Output is expected to increase significantly in the future, increasing the need for pipeline
transportation capacity.7
TransCanada has signed contracts with Bakken oil producers to carry 65,000 bpd from the region
via the Keystone XL pipeline. While not the full 100,000 bpd of capacity TransCanada had
offered to oil producers, this was enough to justify adding the Bakken Marketlink Project, a
pipeline running from Baker, MT, to the Keystone XL pipeline, which can then carry crude to the
oil hub at Cushing, OK, and on to the Gulf Coast.8 The Bakken Marketlink would have a 100,000
bpd capacity and is estimated to cost $140 million. It could start operating in 2013 if it and the
Keystone XL pipeline receive regulatory approvals.9
These new Bakken contracts also improve the economics for Keystone XL, raising its committed
capacity from 75% to near 90% of its projected 830,000 bpd.10 Lower transportation costs and
access to new markets may support investment in the Bakken. And TransCanada is not the only
company adding pipeline capacity. Notably, Enbridge, another Canadian pipeline company, is
building a 145,000 bpd pipeline to transport oil from the Bakken region to markets in the
Midwest in the same time frame. 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.”11
Presidential Permit Application Requirements
Ordinarily, the U.S. government does not have permit authority for oil pipelines, even interstate
pipelines. This is in contrast to interstate natural gas pipelines, which, under Section 7(c) of the
Natural Gas Act, must obtain a “certificate of public convenience and necessity” from the Federal
Energy Regulatory Commission (FERC).12 Generally, the primary siting authority for oil
pipelines would be established under applicable state law (which may vary considerably from
state to state). However, the construction, connection, operation, and maintenance of a pipeline
that connects the United States with a foreign country requires executive permission conveyed
through a Presidential Permit. Since the Keystone and proposed Keystone XL pipelines are
designed for the importation of oil from Canada, their facilities require a Presidential Permit.

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.13 Issuance of a Presidential Permit is dependant upon a
finding that the project would serve the national interest.14 In the course of making that
determination, the State Department consults extensively with concerned federal and state
agencies, and invites public comment in arriving at its determination. Further, in processing
permit applications, the State Department reviews the project’s compliance with the National
Environmental Policy Act (NEPA, 42 U.S.C. § 4321 et seq.), the National Historic Preservation
Act (16 U.S.C. § 470f), the Endangered Species Act (16 U.S.C. § 1531 et seq.), and Executive
Order 12898 of February 11, 1994 (59 Federal Register 7629), concerning environmental justice.
In processing the permit application for the Keystone XL Pipeline project, issues associated with
NEPA compliance have drawn the most attention.
Environmental Review Under the National Environmental Policy Act
Broadly, NEPA requires federal agencies to consider the environmental impacts of their actions
before proceeding with them and to inform the public of those potential impacts. To ensure that
environmental impacts are considered, an environmental impact statement (EIS) must be prepared
for major federal actions “significantly” affecting the environment.15 With respect to the
application submitted by TransCanada, the State Department concluded that issuance of a
Presidential Permit for the proposed construction, connection, operation, and maintenance of the
Keystone XL Pipeline and its associated facilities at the United States border would constitute a
major federal action that may have a significant impact upon the environment within the meaning
of NEPA.16 For this reason, the State Department prepared an EIS to address reasonably
foreseeable impacts from the proposed action and alternatives.
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.17 Accordingly, the State Department EIS
must review and consider the potential environmental impacts of the entire pipeline (including the
construction, operation, and maintenance of the pipeline and its associated facilities), not just the
facilities at the border crossing.

13 See Executive Order 13337, “Issuance of Permits With Respect to Certain Energy-Related Facilities and Land
Transportation Crossings on the International Boundaries of the United States,” 69 Federal Register 25299, May 5,
2004, as amended, and Department of State Delegation of Authority No. 118-2 of January 26, 2006. The source of
Permitting Authority for relevant Executive Orders is discussed further in the Appendix.

January 28, 2009.
17 In preparing an EIS associated with a Presidential Permit, NEPA regulations promulgated by both the Council of
Environmental Quality (CEQ) and the State Department would apply. CEQ regulations implementing NEPA (under 40
C.F.R. §§ 1500-1508) apply to all federal agencies. NEPA regulations applicable to State Department actions, which
supplement the CEQ regulations, are found at 22 C.F.R. § 161.

Keystone XL Pipeline Project: Key Issues

NEPA regulations require preparation of a draft EIS that must be circulated for public and agency
comment, followed by a final EIS that incorporates those comments.18 Preparing the EIS is the
responsibility of a designated “lead agency,” in this case, the State Department. In developing the
EIS, the State Department must rely to some extent on information provided by TransCanada. For
example, TransCanada’s permit application included an Environmental Report which was
intended to provide the State Department with sufficient information to understand the scope of
potential environmental impacts of the project.19
The EIS must also identify any state, tribal, or federal licenses, permits or approvals applicable to
the project in the United States.20 Further, in preparing the draft EIS, the lead agency must request
input from “cooperating agencies” which include any agency with jurisdiction by law or with
special expertise regarding any environmental impact associated with the project.21 Cooperating
agencies for the Keystone XL project are 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 Interiors 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 the Montana Department of Environmental Quality.
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.22 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” (EPA rating of environmental impacts is discussed in more detail, below).
The State Department released its draft EIS for the proposed Keystone XL Pipeline project for
public comment on April 16, 2010.23 The draft EIS identified TransCanada’s “preferred
alternative” (Figure 1) for the project as well as other alternatives considered. On July 16, 2010,
EPA rated the draft EIS “Inadequate.”24 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.

Keystone XL Pipeline Project: Key Issues

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 that a final decision had not been made, the State Department was “inclined to”
approve the project.25 Critics of the project, including some Member of Congress, stated that the
Secretary’s statement appeared to prejudge its permit approval for the pipeline proposal as a
foregone conclusion.26
The State Department issued a supplemental draft EIS on April 15, 2011. In addition to
addressing issues associated EPA’s inadequacy rating, the supplemental draft EIS addressed
comments received from the public and other agencies. On June 6, 2011, EPA sent a letter to the
State Department that rated the supplemental draft EIS as having “Environmental Objections—
Insufficient Information.”27 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. 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 6th letter to the State Department, EPA refers to agreements with the State Department
that certain deficiencies identified in the supplemental draft EIS will 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. After the State Department addresses EPA’s comments, as well as any
additional public and other relevant agency comments to the supplemental draft EIS, the State
Department may issue a final EIS for the project.
As discussed previously, after the final EIS is issued, EPA will then be required to rate the
environmental impacts of the project. The final EIS may receive a rating of either “Lack of
Objections,” “Environmental Concerns,” “Environmental Objections,” or “Environmentally
Unsatisfactory.” The State Department would be required to respond to EPA’s rating, as
appropriate. A rating other than “Lack of Objections” would require the State Department to work
with EPA to reduce the identified environmental impacts. A project with environmental objections
or concerns involves impacts that should be avoided to protect the environment and may also
require some corrective measures such as changes to the preferred alternative or consideration of

25 See Secretary of State Hillary Clinton “Remarks on Innovation and American Leadership to the Commonwealth
Club,” San Francisco, CA, October 15, 2010, available at http://www.state.gov/secretary/rm/2010/10/149542.htm. The
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.
26 For example, see the October 21, 2010 letter from Senator Mike Johanns to Secretary Clinton expressing his concern
that her statement gave the appearance that approval of the pipeline was a foregone conclusion

Keystone XL Pipeline Project: Key Issues

another project alternative. A project with unsatisfactory impacts would be identified as such
based on its impacts to public health or welfare or to the environment. If EPA identifies
unsatisfactory impacts that are not subsequently resolved, the proposal could be recommended for
referral for dispute resolution to the Council of Environmental Quality (CEQ), which oversees
federal agency implementation of the environmental impact assessment process and acts as a
referee when agencies disagree over the adequacy of such assessments.
Issuing a Final Record of Decision and National Interest Determination
The NEPA review is complete when the State Department issues a final Record of Decision
(ROD), formalizing the selection of a project alternative. A Presidential Permit may be granted or
denied once the State Department determines whether the project is in the national interest. For
previous Presidential Permits, a ROD and National Interest Determination were issued as the
same document.28
Issuance of the ROD and National Interest Determination involve distinctly different, yet
interrelated requirements. Under NEPA, the State Department must fully assess the environmental
consequences of an action and potential project alternatives before making a final decision. NEPA
does not prohibit a federal action that has adverse environment impacts, it requires only that a
federal agency be fully aware of and consider those adverse impacts before selecting a final
project alternative. That is, NEPA is intended to be part of the decision-making process, not
dictate a particular outcome. The State Department’s decision to issue a Presidential Permit,
however, dictates a particular outcome—that a Permit will not be granted unless it is determined
that the project is in the national interest. While NEPA does not prohibit federal actions with
adverse environmental impacts, a project’s adverse environmental impacts may lead the State
Department to determine that it is not in the national interest.
With regard to the consideration of environmental impacts in making a national interest
determination, the fact that similar pipeline projects (e.g., the Alberta Clipper and the Keystone
pipelines) have recently been determined to be in the national interest does not necessarily
constrain the review of Keystone XL Pipeline project. The proposed route and end points of the
Keystone XL Pipeline are unique, and thus may involve distinct environmental impacts. For
example, in its determination that the supplemental draft EIS provided insufficient information,
EPA expressed concerns regarding potential risks to the Ogallala Aquifer and environmental
justice issues associated with the Port Arthur and Houston, TX, refineries. Although the approved
Keystone pipeline also crosses the Ogallala Aquifer, it does so in a different location where the
aquifer may have different characteristics in terms of depth, soil permeability, and other
geological factors. (The aquifer issue is further discussed in a subsequent section.) Thus, specific
environmental concerns unique to the Keystone XL project may lead to different conclusions and
will need to be addressed to the satisfaction of EPA.
The State Department announced that once it issues a final EIS, interested federal agencies, such
as the Department of Energy and EPA, will have 90 days to provide their opinion on whether
issuance of a Presidential Permit would be in the national interest.29 Further, during the first 30

Keystone XL Pipeline Project: Key Issues

days of this 90-day review period, the State Department plans to host public meetings in each of
the five states through which the proposed pipeline would pass (Montana, South Dakota,
Nebraska, Oklahoma, and Texas) and in Washington, DC. These meetings are intended to give the
public an additional opportunity to voice their concerns on issues they think should be taken into
account in determining whether granting or denying the Presidential Permit would be in the
national interest. These additional public meetings are not part of the NEPA process.
The State Department has indicated that it expects to make a decision on whether to grant the
permit before the end of 2011. The North American-Made Energy Security Act (H.R. 1938) was
introduced on May 23, 2010, and approved by the House Energy and Commerce Committee on
June 23, 2011. It would direct the President to expedite the State Department’s permit review
process, requiring a final decision to grant or deny the permit no later than November 1, 2011.
H.R. 1938 is motivated by the perception among some in Congress that the State Department is
taking too long to review an energy infrastructure project critical to national security and
economic growth.30 Opponents of the bill argue that the project’s unique and potentially
unacceptable safety and environmental risks, as well as its uncertain impacts on fuel prices,
require more time for analysis and evaluation.31
Whatever the State Department’s final decision, legal challenges appear likely. 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.32 So the final EIS associated with the Keystone XL Pipeline may be subject to
judicial review, but the State Department’s national interest determination, made under its
authority to issue of a Presidential Permit, is not. For more information regarding the State
Department’s authority to grant a Presidential Permit, see the Appendix.
State Siting and Environmental Approvals
As noted above, the federal government does not exercise siting authority over oil pipelines.
Siting for the Keystone XL pipeline still must comply with any applicable state laws. These laws
vary from state to state. South Dakota, for example, required TransCanada to apply for a permit
for the Keystone XL pipeline from the state public utility commission, which issued the permit on

Keystone XL Pipeline Project: Key Issues

Quality,34 but has not yet granted one for the Keystone XL project. Nebraska does not appear to
have any permitting requirements that apply 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.35 A number of additional approvals and
permits required by the states along the proposed route are summarized in TransCanada’s
Presidential Permit application.36 All of the aforementioned state approvals are in various stages
of review along the proposed Keystone XL pipeline route.
Arguments For and Against the Pipeline
Proponents of the Keystone XL pipeline, including Canadian agencies and U.S. and Canadian
petroleum industry stakeholders, base their positions primarily on increasing the diversity of the
U.S. petroleum supply and economic benefits to the United States, including job creation.
Opponents, primarily environmental groups and affected communities along the route, object to
the project principally on the grounds that Canadian oil sands development has negative
environmental impacts and that it promotes continued U.S. dependency on fossil fuels. These
issues are further discussed below.
Impact on U.S. Energy Security
In its Presidential Permit application, TransCanada asserts that constructing the proposed
Keystone XL pipeline is in the U.S national interest to maintain adequate crude oil supplies for
U.S. refineries. The application argues that the pipeline will allow U.S. refiners to substitute
Canadian supply for other foreign crude supply and to obtain direct pipeline access to secure and
growing Canadian crude output. In particular, the application asserts that the pipeline would allow
the United States to decrease its dependence on foreign crude oil supplies from Mexico and
Venezuela, the two largest oil importers into the U.S. Gulf Coast.37 In its draft EIS for the project,
the State Department similarly finds that the Keystone XL pipeline “would counteract insufficient
domestic crude oil supply while reducing U.S. dependence on less reliable foreign oil sources.”38
These arguments have taken on additional weight in light of the ongoing political unrest in the
Middle East, which has disrupted oil production in Libya, a significant oil exporter, and has
caused a spike in global crude oil prices.

Keystone XL Pipeline Project: Key Issues

Canadian Oil Imports in the Overall U.S. Supply Context
Gross U.S. imports of crude oil and petroleum products averaged 11.8 million barrels per day
(Mbpd) in 2010.39 Exports averaged 2.3 Mbpd, leaving net imports at 9.4 Mbpd.40 U.S. net
imports declined each year between 2005 and 2010 as a result of lower total oil demand and
higher domestic supply. Domestic demand has decreased by about 1.7 Mbpd versus 2005 levels
due largely to the economic recession. Meanwhile, U.S. production of oil and oil alternatives
(including crude oil, natural gas liquids, and biofuels) has increased by 1.4 Mbpd since 2005. As a
result, net imports fell by roughly 3.1 Mbpd since 2005.41 Some of this decline could be mitigated
in the near term as oil demand recovers from the recession or if domestic supply were to fall.
However, there is increasing consensus among forecasters that U.S. net oil imports have passed
their high water mark already and may remain relatively flat in the long run.42
Among the largest sources of U.S. gross oil imports are Canada (2.5 Mbpd), the Persian Gulf (1.7
Mbpd), and Mexico (1.3 Mbpd). Imports from the latter two sources have decreased in recent
years in part due to lower need for imports described above and in part due to developments in
those countries (Figure 2). All major Persian Gulf exporters are members of the Organization of
the Petroleum Exporting Countries (OPEC), which cut production in 2009 to support oil prices.
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, has 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 Mb/d 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.43

(http://tonto.eia.doe.gov/cfapps/ipdbproject/IEDIndex3.cfm).
40 For context, the United States consumes roughly 19 Mbpd, 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 Mb/d to Mexico.

Meanwhile, Canadian production and exports to the United States have increased, primarily due
to growing output from the oil sands in Western Canada. Energy markets in the United States and
Canada are well integrated by pipeline infrastructure, and nearly all Canadian energy exports go
to U.S. consumers.44 Canadian oil production has increased about 0.2 Mbpd since 2005, and
exports to the United States increased by 0.4 Mbpd (Figure 3).45 Canadian oil production is
expected to grow by as much as 1.6 Mbpd between 2009 and 2025, mostly through increased
output from the oil sands.46

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 upgraded into “syncrude” that is
suitable for pipeline transport. Canada’s oil sands production is expected to be exported as either
a light, upgraded synthetic crude or a heavy crude oil that is a blend of bitumen diluted with
lighter hydrocarbons to ease transport. The bulk of oil sands supply growth is expected to be in
the form of the latter.47 Most oil sands imports into the United States currently go to the Midwest,
where some refineries are investing in complex refining capacity to process growing volumes of
heavy Canadian crude.48 The U.S. Gulf Coast region already has a large amount of complex
refining capacity and is considered potentially well suited for processing Canadian heavy crude
oil.49 Gulf Coast refiners currently process heavy crudes from Venezuela, Mexico, and elsewhere.
Complex refineries in the Gulf Cost 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,50 especially if the new Canadian
crudes will be used in large amounts.51 There are 15 refineries within Keystone XL’s proposed
delivery area in Texas that currently process heavy crude oil which is similar in composition to
the oil that the pipeline would bring down.52

Keystone XL Pipeline Project: Key Issues

With expanded pipeline capacity extending to the U.S. Gulf Coast, Canadian oil sands crude may
compete with other heavy crudes such as those from Mexico, Venezuela, and elsewhere.53 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.54 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.
In 2010, 98% of Canada’s oil exports went to the United States, mostly through north-south
pipelines. One 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. Currently, about 90% of the crude shipped out by sea goes to California, with the
remainder shipped to the U.S. Gulf Coast and Asia.55
There are proposals to increase the capacity for oil from Alberta to reach the Canadian west coast.
Kinder Morgan is considering expanding the Trans Mountain Pipeline to 700,000 bpd, more than
doubling its existing capacity, and expanding west coast shipping facilities. Enbridge has
proposed a new pipeline: the Northern Gateway project would have a 525,000 bpd capacity to
send oil from Edmonton to Kimat, British Columbia.56 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. Both 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.57
If export capacity to the west coast is expanded it could increase the amount of Canadian crude
oil going to non-U.S. markets. Canadian oil sales to Asian markets, where oil demand is growing
rapidly, are more likely to develop if greater shipments to the United States are not possible.58 A
study commissioned by the Department of Energy concluded 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.59
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.”60 A 2009 report from the Canadian Energy
Research Institute (CERI) commissioned by the American Petroleum Institute similarly concludes
that:
As investment and production in oil sands ramps up in Canada, the pace of economic activity
quickens and demand for US goods and services increase rapidly, resulting in an estimated
343 thousand new US jobs between 2011 and 2015. Demand for US 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 2025.61
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.62 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.
Canadian Oil Sands Environmental Impacts
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.63 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.64 Large amounts of water and natural

gas are also required (for heating) during the extraction process.65 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.66 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.67
Possible Risks to the Ogallala Aquifer
The proposed route of the Keystone XL pipeline passes across significant portions of the Ogallala
Aquifer (Figure 4), one of the world’s largest known aquifers and the primary source of
groundwater for approximately 20% of U.S. agricultural production.68 Because the aquifer is
relatively close to the surface, some stakeholders are concerned that a release from the pipeline
could potentially contaminate the aquifer with oil, jeopardizing its use for farming and drinking
water and causing significant ecosystem damage. These concerns have been heightened in the
wake of the 2010 spill from an Enbridge oil pipeline in Marshall, MI, which released 819,000
gallons of crude into a tributary of the Kalamazoo River. Furthermore, a report by the Natural
Resources Defense Council (NRDC) argues that the Keystone XL pipeline could be more likely
to fail and cause environment damage than other crude oil pipelines because the bitumen mixture
it would carry is “significantly more corrosive to pipeline systems than conventional crude,”
among other reasons.69 Canadian officials and other stakeholders have rejected these arguments,
however, citing factual inaccuracies and a flawed methodology in the analysis, which compares
pipeline spill rates in Canada to those in the United States.70
In its draft EIS for the Keystone XL pipeline project, the State Department states that “there is the
possibility that a release could migrate through the overlying surface materials and enter a
groundwater system.”71 Nonetheless, the department concludes that “the probability of a large
spill occurring is very low, and, consequently, risk of environmental impacts is minimal.”72 The
draft EIS views the risks of aquifer damage from the Keystone XL pipeline independently from
such risks from other pipelines. Because the probability of a pipeline spill and subsequent

Fossil Fuels Dependence
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.74 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.”75 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 recommends that the final EIS include discussion of mitigation
approaches for greenhouse gas emissions from extraction activities that are either currently or

could be employed to help lower lifecycle greenhouse gas emissions.76 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 geographies (e.g., China).77

Keystone XL Pipeline Project: Key Issues

Appendix. Presidential Permitting Authority
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 1968.78 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. 11423.79 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.”80 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.81
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.82
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. 83
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).84 The court stated that the authority to regulate the cross-
border pipeline lies with either Congress or the President.85 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.”86 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.87

Keystone XL Pipeline Project: Key Issues

In Sierra Club v. Clinton,88 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).89 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.”90 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.91
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.”92 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
judicial review of such decisions would raise separation of powers concerns. Ibid. at 111.

analyzing the validity of presidential actions in relation to constitutional and congressional authority).
