What infrastructure systems does your system rely on for operations? 

• Does the facility or system depend on public water utilities for normal operations?
• Does the facility or system depend on an external electrical utility provider as your primary electric power source?
  • Is there on-site generator capacity or contracted generator capacity?
  • What portion of operations can it sustain?
  • Is there a plan in place for fuel delivery?
• Does the facility or system depend on natural gas or fuel?
• Does the facility or system rely on communications systems to function (internet, industrial control technology/SCADA)?
• Does the facility or system rely on key transportation routes (road, rail, maritime, air) for access (ingress/egress) or delivery of inbound/outbound materials?

Within your system, are there particular nodes or facilities that are especially critical to system operations? (i.e., single points of failure)
