Thank you, Mr. Chairman. I recognize that it's currently a federal responsibility for the waters. You've said that, obviously, there are concerns and there are no current ocean dumping sites. I pointed out in my statement a couple of days ago, that it's also recognized that in the past there have been ocean dumping sites. Are those sites now identified? I had posed that question to the Minister that day, but he wasn't quite sure, so I'm just trying to get that clarified.
