With respect to that, those are goods we would classify as dangerous goods. They are covered under the Transportation of Dangerous Goods Act. First and foremost, they have to have an appropriate means of containment to transport those goods. They also have to have what we call an ERAP, an emergency response activation plan, so that if anything goes wrong, they have a plan in place and they can activate that plan should it be necessary.
We also have provisions now within the TDG Act for security measures for goods that could be considered for the use of terrorism or what have you. We're in the process of developing regulations in that regard as to what measures we might want to use should a security situation arise.
