When pipelines are your business, you pride yourself on ensuring the safest delivery through the communities you operate in.
TransCanada happens to be in that business, and we are using the latest in pipeline technology to make sure we live up to that expectation.
One of the realities of transporting energy across the continent is that our pipelines will have to cross bodies of water. A considerable amount of the media attention regarding the path of Keystone XL concerns the Ogallala Aquifer.
The Ogallala Aquifer provides drinking water to millions of people, plants and animals in the region. Some estimates say that the total amount of water in the aquifer could cover the continental United States in water two feet deep. The Ogallala is incredibly important to the people of the Midwest. We know this because our friends and families live and work up and down Keystone route too. We take special care building our pipelines; that’s why we’ve voluntarily agreed to add 59 additional safety and maintenance conditions. Keystone XL will be the safest and most technologically advanced pipeline built in the United States.
Our opponents would have you believe that the Keystone XL pipeline would risk this entire resource. This is not true, nor is it supported scientifically.
Dr. Jim Goeke, a research hydrologist and professor emeritus at the University of Nebraska-Lincoln, has studied the Ogallala Aquifer for four decades.
According to Goeke, his 40 years of research and study of this unique structure have demonstrated repeatedly that the water in the Ogallala Aquifer follows gravity, and thus flows west-to-east. Take a look at the pipeline route below.
Keystone XL’s path is east of more than 80 per cent of the Ogallala Aquifer. Impact modelling conducted by the State Department and the Nebraska Department of Environmental Quality has shown that in the very unlikely event of an incident, impacts would be localized to as little as tens of feet. That’s because the Ogallala Aquifer is a very large rock formation with layers and layers of sands, soils and rock layers. These thick layers offer a natural protection for the water below. For context, water travels through the Aquifer’s densely packed layers at a rate of two to three feet a day.
In the New York Times Professor Goeke, gives a number of explanations as to why Keystone presents minimal risk; highlighting that the depth of the water along much of the alignment of the pipeline is between 50 and 300 feet deep. Keystone would be buried four feet deep.
Any claim that the drinking water for the entire region would be affected is a gross exaggeration of the risks
And in areas where the water table sits closer to the planned pipeline depth? TransCanada has already pledged to utilize waterproof coverings on the pipeline and cement jackets during construction. Remotely operated shutoff valves will be spaced closer together and can stop the flow of oil in minutes.
Further to that, TransCanada uses high-quality carbon steel, capable of withstanding the 3.5-inch teeth from a 65-ton excavator. We also use a corrosion-resistant, fusion-bonded epoxy coating. In order to further shore up the integrity of our pipelines, we attach cathodic protection to our infrastructure. This is the same technique used on bridges, boats and cars to prevent rust from occurring.
Our safety procedures and pipeline paths are based on scientific evidence. Support from in-state academics like Prof. Jim Goeke gives us the confidence to know what we are doing is safe. The support of more than 60% of the American public gives us the support to know what we are doing is in the best interest of the country.
The Keystone XL Pipeline, when complete, will be over 2,000 miles (3,462 km) long.
