As I mentioned, under our arrangement we've confirmed that the United States has an environmentally sound management of non-hazardous waste and scrap that are subject to transboundary movement. A company that is wanting to transit through the United States and export to another country is required to obtain an export permit.
However, having said that, no environmental regime is bulletproof. Should someone choose to contravene the regulations and take actions that are not permitted, our regulations and legislation don't prevent that. That's when our enforcement regime comes into play. We need to follow up and make sure we're taking corrective action. The the same holds true for the United States, or any other country for that matter.
On that note, I might just say that Canada has taken action recently with respect to the illegal export of waste and has put in place an operation with a number of other countries to look at whether we are effectively managing these wastes. This exercise was undertaken with Canadian border services as well.
