The determining factor here is not that the risk is immediate, but rather that it is ongoing and persistent. The issues we have kept on the watchlist are there because the actions we think would better mitigate the risk have not yet been taken.
Concerning the transportation of flammable liquids, we realize that the risk involved in the transportation of dangerous goods by any mode of transportation is ongoing. In this case, the actions we wanted to see in terms of analysis, risk management and use of more crash-resistant tank cars have been taken. So we have removed that issue from the list.
However, we continue to monitor the statistics and conduct our investigations when necessary. No action has yet been taken in response to three of the five recommendations we issued in relation to the Lac-Mégantic incident, or in response to two other recommendations we proposed after other derailments in 2015. So it is clear that we have not stopped monitoring that safety issue.
