For the past two years, there has been a manufactured myth circulating that diluted bitumen is corrosive in pipelines. It began with a report created by the Natural Resources Defense Council (NRDC). This report tried to "prove" diluted bitumen is more corrosive than conventional crude. We know that this is not true, but it is easy for the public to believe this myth when the report appears to be genuine and scientific. The reality is, many of the allegations in the NRDC report are completely false, including the one about diluted bitumen.
