Keystone XL Pipeline Pros and Cons

We  asked our Zintro experts about the pros and cons of the proposed  TransCanada Keystone XL Pipeline. What are the risk factors for the  environment? What kind of benefits does the 
pipeline offer? Here are their responses.
Foboni, an expert in risk and crisis management and risk-based decision making, says that he is participating in the review and 
risk assessment  of a large, long-term project in Northern Canada (Arctic). “Long-term  projects around the world, and in particular in the Arctic region, are  exposed to a large number of 
hazards  deriving from extreme conditions, and in particular climate change.  Warming and the resulting loss of permafrost (the permanently frozen  layer of soil and rock) are causing trouble and will bring havoc in the  future to the natural environment, and of course, to any permanent  structure,” says Foboni. “If proper risk-based decision making has not  been performed from inception, with well balanced and sustainable  mitigative programs, the hazards will have unpleasant consequences.”
Nigel, an environmental consultant with a blue chip oil and gas background,  says the challenges of the Keystone XL Pipeline have been largely met  in many locations, including the Alaskan/Canada corridor and many parts  of Russia and other cold temperate and arctic zones. “The primary  concern should be for the Tundra, in that a buried pipe may not only  threaten the delicate balance of temperature, but interfere with fauna  associated with these zones,” he says. “Vibration and the potential heat  associated with the passing crude may have an impact. Pipeline  integrity from the point of view of corrosion monitoring and regular  pigging would be an essential provision. Pipeline integrity from the  point of view of damage from collision or sabotage is equally  important.”
Nigel points out that pumping stations are required  throughout the route, with consequential infrastructure associated with  the servicing of these stations and way leave examination. Provision for  migration routes is needed and a route avoiding areas of special  sensitivity should be considered. “Depending upon population density,  some economic value may be available for isolated communities in  supporting the pipeline construction and consequential supervision,”  says Nigel. “However, the case is more likely to be made around the  cost-benefit case of accessing the tar sands and generating refined  product. The energy costs and 
environmental impacts, such as energy consumption (fossil or non-fossil), carbon dioxide emissions, and 
hazardous waste, from production have a cost”.
Dr. Kilpatrick, an economic policy consultant, says that liquid 
petroleum products made from 
refined  crude oil are primarily used in transportation and manufacturing with a  small amount used for home heating, mainly in the Northeast. They  cannot be entirely replaced by more environmentally friendly fuels, such  as solar and wind, unless and until vehicles are powered by  electricity. “At this point, who knows what the law of unintended  consequences of that path might be? Meanwhile, the demand for this oil  exists, and it will be supplied from somewhere,” says Kilpatrick. “Gas  and oil pipelines are built all over the US, usually with little  opposition. While human error and corrosion do cause some amount of  environmental damage, pipelines are the safest, most environmentally  friendly means of transporting hydrocarbons. The root of the opposition  to the Keystone XL Pipeline seems to be the production of oil from tar  sands in Alberta, CA.”
Kilpatrick says that it is hard to get a  handle on how many jobs the pipeline will create. “Most of the numbers  are produced by sources with a stake in the outcome, and thus not  reliable. I would argue that it will primarily create temporary  construction jobs and provide a short term boost to motels, restaurants,  and shops in towns along the pipeline route. But, the number of people  needed to actually operate the pipeline, including inspection and  maintenance, will not be large.”
Alan Herbst, an energy consultant,  says that after years of planning, regulatory and environmental review,  on August 26, 2011, the US State Department released the Final  Environmental Impact Statement for TransCanada’s Keystone XL pipeline  project. This review stated there were no environmental obstacles  present to prohibit the pipeline’s development and is expected to result  in US State Department approval of the project, the last significant  hurdle necessary for its permitting and construction.
“The XL  project is an expansion of the existing 600k b/d Keystone pipeline that  runs from Alberta, Canada to refineries in Illinois and storage  facilities in Cushing, Oklahoma. The XL expansion will provide an  additional 700k b/d of pipeline capacity and enable crude oil from  Canada and North Dakota’s Bakken field to reach refineries in Houston  and Port Arthur, Texas,” explains Herbst.
“Proponents of Keystone  XL cite the economic benefits (direct and indirect job creation, greater  tax revenue and potentially lower oil prices) resulting from the  multi-billion dollar project. Opponents have expressed concerns over  potential pipeline leaks that could pollute surface water and area  aquifers,” says Herbst. “Some pipeline opponents are looking to hinder  the further development of Alberta 
oil sands sector by attempting to limit further construction of regional pipeline takeaway and export capacity.”
While  safety and the environment are legitimate concerns, the XL expansion  project will meet or exceed all US pipeline safety regulations, will be  constructed from high strength steel, and have a fusion bonded epoxy  coating along with active cathodic protection to prevent corrosion. “The  pipeline will be remotely monitored 24-hours a day and buried at depths  from 4 to 25+ feet depending on location. These features permit the  safe construction and operation of the Keystone XL pipeline,” says  Herbst.
Herbst says that the pipeline, which is expected to enter  service in 2013, will provide an outlet for the increasing amounts of  crude oil entering Cushing, which has created a supply glut (currently  31 million barrels are in storage) and depressed prices at the NYMEX  delivery point. “This abundance of supply has inverted and widened the  Brent/WTI spread, which at times has Brent trading at a $25 premium to  WTI. Brent, a slightly lower quality crude, was traditionally valued at a  $1.25-$1.75 discount to WTI,” he says. “Once the Keystone XL pipeline  and one or two other pipelines are built to increase crude oil transport  capacity to the US Gulf, the Brent/WTI spread will begin to narrow and  possibly revert back to its traditional pricing relationship. This  pipeline development will also provide US Gulf refiners with access to  growing amounts of high quality Canadian and US crude, lessening their  reliance on oil imports from Europe, Africa, Mexico and South America.”
