U.S. scientists are warning that there are environmental risks, regulatory holes and serious unknowns regarding the shipment of Alberta oil-sands products by pipeline, rail and tanker. The findings are in a 153-page report from last September by the emergency response division of the U.S. National Oceanic and Atmospheric Administration. The unit has expertise in preparing for, evaluating and responding to oil and chemical spills in coastal environments. [And see the final report here of a University of Washington team dated March 2013 on which the NOAA report was based.]
