New Report Assesses Likelihood of Transported Diluted Bitumen Release


A new report from the National Research Council assesses the likelihood of pipeline releases of shipments of diluted bitumen compared with shipments of other crude oils, taking into account their chemical and physical properties, accident data, and pipeline operations and  maintenance.


Since 2000, imports of Canadian diluted bitumen through major pipelines in the United States, including the Keystone pipeline, have increased by one-third.  Legislation enacted in January 2012 called upon the secretary of transportation to determine whether releases are more likely to occur when pipelines transport this form of petroleum.  The U.S. Department of Transportation in turn asked the Research Council to convene an expert committee to analyze whether shipments of diluted bitumen have a higher likelihood of pipeline release compared with shipments of other crude oils. 



Advance copies of the report will be available to reporters only starting at 3 p.m. EDT Monday, June 24. The report is embargoed and not for public release before noon EDT Tuesday, June 25th. Members of the study committee will take questions during a one-hour telephone news conference for reporters only beginning at 12:15 p.m. EDT June 25. To obtain an embargoed copy and call-in details for the telephone news conference, contact the National Academies' Office of News and Public Information; tel. 202-334-2138 or e-mail
