Thank you, Madam Chair. Yes, in terms of going through and figuring out the fuel that's coming up, there's a very rigorous process that come in where they test fuel based on the shipments. The situation the Minister was talking about, we got into a situation where we couldn't bring rail cars through because of the fire and high level, so we ended up having to truck. Every case that you do in terms of that testing amount is in the thousands of dollars, and so, as you go through and test those carloads of fuel to make sure that it has spec and it meets spec, along the way, we do that to ensure as we're transferring fuel. I would say that, even where we had that fuel that was under spec, the folks in fuel services were able to get some engineers on that fairly quickly, and actually made all that fuel right back up to grade, and we were able to do that very efficiently. There was no wastage of any fuel. At no point did anybody not have access to fuel during that situation. Thank you, Madam Chair.
