Yes, when I attended the site of the spill—I think that was on Saturday 8 October—I met with Valero and NRW, and I was very pleased to see the way that they were working together. But, you’re quite right; at that time, the cause of the spill had not been identified, but it is really important—it's a very long pipe—it's really important that that's monitored in a way that absolutely we learn all the lessons we can to avoid that sort of spill again.
