Chairman, I'm going to ask in a moment for a comment from the officials, if I may, on the first of the two paragraphs proposed in this amendment. I am certainly concerned about the idea particularly of drilling under the ice in the Arctic where we would not have the capacity to contain or clean up a spill. That would be a huge concern if the government were actually to go ahead and permit that without those kinds of capabilities. Obviously, there are reasons to assess that risk, but I'd like to ask officials what impact this would have on the bill.
