Senator LEVIN. OK, at NISAC. This is part of the Department of Homeland Security, and it was performed on August 27, this computer simulation, and it is Exhibit K, and there was an update performed on August 28, and this was delivered to the White House Situation Room at 1:47 on Monday morning, August 29. This NISAC report stated that the potential for severe storm surge to overwhelm Lake Pontchartrain levees is the greatest concern for New Orleans according to the NISAC report. So Homeland Security knew prior to the breach of the levees, at least a number of hours before the breach of the levees, that this was the greatest concern for New Orleans. Do you know where the NISAC folks got that terminology, Mr. Fairley?
Mr. FAIRLEY. No, sir, I do not.
Senator LEVIN. But is it fair to say that in terms of the impact of a severe, catastrophic storm that it was known that the breach of the levees could be one of the impacts?
Mr. FAIRLEY. Yes, sir, I think in all of the planning scenarios and past disasters that we always knew that a breaching or an overtopping of the levee could lead to——
Senator LEVIN. Either one?
Mr. FAIRLEY. Either one.
