Dr. Tom Ryan:

I can clarify that. We recognise that there was an informal attempt to contact the EPA on the 11th. A message was left on an EPA inspector's phone at 5.20 p.m. on the 11th. That message was not received so it was not an effective communication. It did not come through the EPA out-of-hours emergency service, which would have activated our teams immediately. So we did find out the next morning. That said, because we have access to all sorts of on-site data, which means we can interview licensees and check logbooks, at the end of the day it was not material to our investigation or to the conclusions that we drew. Of course we would like to hear about this immediately.
