Thank you, Madam Chair. If you're referring to a couple of years ago when that all happened, no, just in general. Well, I'll refer to that incident anyway, where fuel was not good when it showed up. The department looked at that. They took a look at their procedures through that, and they implemented measures afterwards, to not have the bad fuel sale again, and they did put in more controls. I don't know if Dr. Dragon would like to add to that, but I'll give him an opportunity to do so. Thank you, Madam Chair.
