NACE International – The Corrosion Society along with three of its ‘Fellow’ membership will participate on a newly appointed National Academy of Sciences (NAS) committee formed to analyze whether diluted bitumen (dilbit) transported by transmission pipeline has an increased potential for release compared with pipeline transmission of other crude oils. The NACE Fellows are Dr. Brenda J. Little of the Naval Research Laboratory, Dr. Srdjan Nesic of Ohio University and Dr. Joe H. Payer of the University of Akron.
A chief concern about the transport of Canadian crude through the proposed Keystone XL pipeline is a claim that dilbit poses more release risks than other types of crude. In particular, the committee will examine whether there is evidence that dilbit has corrosive or erosive characteristics that elevate its potential for release from transmission pipelines when compared with other crude oils. Should the committee conclude there is no evidence of an increased potential for release, it will report this finding to the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) by spring 2013. Alternatively, if the committee finds evidence indicating an increased potential, it will examine the adequacy of PHMSA’s pipeline safety regulations in mitigating any increased risk and report back to PHMSA by the fall of 2013.
“With all of the controversy surrounding Keystone XL, it is very important that a well-qualified team analyzes the risks, if any, of diluted bitumen,” said NACE Executive Director Bob Chalker. “NAS has put together the right group for the job. NACE supports this effort and I will be interested, along with many others, in seeing the final results.”
