National Infrastructure Advisory Council (NIAC): The Framework for Dealing with Disasters and Related Interdependencies Working Group [open pdf - 54KB]
"This study focused on the United States' ability to respond to and recover from a major disaster that could result in a prolonged loss of infrastructure services expanding beyond a local area. The desired outcome was to identify areas that are impediments to private sector and local/state government recovery of critical infrastructures, and deployment of needed federal resources." The investigation "included analysis of all relevant sectors identified as Critical Infrastructures and Key Resources (CIKR) by the National Infrastructure Protection Plan (NIPP)."
