For us, this provision is basically a part of a bigger security prevention program. It's true that our first intention is to deal with cross-border transport, but I think it's important that we get the authority to require that people transporting very dangerous goods in very large quantities be required to have a security clearance. Not only that; we understand that they are licensed, but under the Transport of Dangerous Goods Act, there's no review of their background, and we need to do this.
