The Congressional Research Service (CRS), the public policy research arm of Congress, recently issued the report Oil Sands and the Keystone XL Pipeline: Background and Selected Environmental Issues (Feb. 21, 2013). The 56-page report authored by Jonathan L. Ramseur, Richard K. Lattanzio, Linda Luther, Paul W. Parfomak, and Nicole T. Carter discusses the following:
Summary
If constructed, the Keystone XL pipeline would transport
crude oil (e.g., synthetic crude oil or diluted bitumen) derived from oil sands
in Alberta, Canada to destinations in the United States. Because the pipeline
crosses an international border, it requires a Presidential Permit that is
issued by the Department of State (DOS). The permit decision rests on a
“national interest” determination, a term not defined in the authorizing
Executive Orders. DOS states that it has “significant discretion” in the
factors it examines in this determination.
Key events related to the Presidential Permit include
- November 10, 2011: DOS announced it needed additional
information concerning alternative pipeline routes through the Nebraska
Sandhills.
-
January 18, 2012: In response to a legislative mandate in
P.L. 112-78, DOS, with the President’s consent, announced its denial of the
Keystone XL permit.
- May 4, 2012: TransCanada submitted a revised permit
application to DOS.
- January 22, 2013: Nebraska Governor approved TransCanada’s
new route through Nebraska.
Although some groups have opposed previous oil pipeline permits,
opposition to the Keystone XL proposal has generated substantially more
interest among environmental stakeholders. Pipeline opponents are not a
monolithic group: some raise concerns about potential local impacts, such as
oil spills or extraction impacts in Canada; some argue the pipeline would have
national energy and climate change policy implications.
A number of key studies indicate that oil sands crude has a
higher greenhouse gas (GHG) emissions intensity than many other forms of crude
oil. The primary reason for the higher intensity: oil sands are heavy oils with
a high viscosity, requiring more energy- and resourceintensive activities to
extract. However, analytical results vary due to different modeling assumptions.
Moreover, industry stakeholders point out that many analyses indicate that GHG emissions
from oil sands crude oil are comparable to other heavy crudes, some of which
are produced and/or consumed in the United States.
Because of oil sands’ increased emissions intensity, further
oil sands development runs counter to some stakeholders’ energy and climate
change policy objectives. These objectives may vary based on differing views
concerning the severity of climate change risk and/or the need for significant
mitigation efforts. Opponents worry that oil sands crude oil will account for a
greater percentage of U.S. oil consumption over time, making GHG emissions
reduction more difficult.
On the other hand, neither issuance of a Presidential Permit
nor increased oil sands development would preclude the implementation of
energy/climate policies that would support less carbon intensive fuels or
energy efficiency improvements.
A primary local/regional environmental concern of any oil pipeline
is the risk of a spill. Environmental groups have argued that both the
pipeline’s operating parameters and the material being transported imposes an
increased risk of spill. Industry stakeholders have been critical of these
assertions. To examine the concerns, Congress included provisions in P.L.
112-90 requiring a review of current oil pipeline regulations and a risk
analysis of oil sands crude.
Opponents of the Keystone XL pipeline and oil sands development
often highlight the environmental impacts that pertain to the region in which
the oil sands resources are extracted. Potential impacts include, among others,
land disturbance and water resource issues. In general, these local/regional
impacts from Canadian oil sands development may not directly affect public health
or the environment in the United States. Within the context of a Presidential
Permit, the mechanism to consider local Canadian impacts is unclear.
