New Report by the US National Academy of Sciences Confirms Diluted Bitumen Not Corrosive
June 26, 2013 | News Releases

Calgary, June 26, 2013 – A new report by the US National Academy of Sciences (NAS) concludes that diluted bitumen is not more corrosive than conventional crude.

Brenda Kenny, President and CEO, of the Canadian Energy Pipeline Association (CEPA), is pleased with the results of the report, which adds to the growing body of evidence that dispels the myth, that some industry critics have manufactured regarding the transportation of diluted bitumen.

“Based on scientific facts and our pipelines operational histories, the conclusion made by such a reputable organization like the NAS, reinforces what we have always known, diluted bitumen is no more corrosive than conventional crude,” Kenny said.

The report states that the NAS committee does not find any causes of pipeline failure unique to the transportation of diluted bitumen. Furthermore, the committee does not find evidence of chemical or physical properties of diluted bitumen that are outside the range of other crude oils or any other aspect of its transportation by transmission pipeline that would make diluted bitumen more likely than other crude oils to cause releases.

“It is important to have scientific evidence in front of Canadians, so they can make their own informed decisions and not rely on misinformation”, Kenny said. “Misinformation about our industry only perpetuates fear and we know that crude oil, including diluted bitumen has been transported safely by our members for decades.”

Earlier this year, the UK-based Penspen Group also released a report that reached the same conclusion as the NAS report, which was that diluted bitumen is no more corrosive than conventional crude. Copies of that report can be found on CEPA’s website or by clicking here.

The Canadian Energy Pipeline Association represents Canada’s transmission pipeline companies who operate approximately 114,000 kilometres of pipelines in Canada. In 2012, these energy highways moved approximately 1.2 billion barrels of liquid petroleum products and 5.1 trillion cubic feet of natural gas. CEPA members transport 97 per cent of Canada’s daily natural gas and onshore crude oil from producing regions to markets throughout North America.

The National Academy of Sciences (NAS) is a private, non-profit society of distinguished scholars. Established by an Act of Congress, signed by President Abraham Lincoln in 1863, the NAS is charged with providing independent, objective advice to the nation on matters related to science and technology. Scientists are elected by their peers to membership in the NAS for outstanding contributions to research. The NAS is committed to furthering science in America, and its members are active contributors to the international scientific community. Nearly 500 members of the NAS have won Nobel Prizes, and the Proceedings of the National Academy of Sciences, founded in 1914, is today one of the premier international journals publishing the results of original research.
