In general, the issue arose in the fall. We brought together two different types of actions. One was a protective direction that was put in place. The other was to require shippers to do up-to-date testing of their goods, their crude oil products. If they do not have an immediate test result available, then they must ship it as the highest classification of dangerous goods flammable liquid, and in the meantime, they have to do the testing and give us the results. Those test results are informing our understanding of what the requirements should be. We are also working very closely with the U.S. regulators who have been carrying out studies and tests of the products in the U.S. Information is shared with them and it also informs our knowledge.
The working group which was created under our policy advisory council has given advice and recommendations and has brought together work on a series of scientific areas like vapour testing of the products and how to do more accurate testing in the field. Studies are under way in that regard. All of those are accumulating next actions to be proposed.
