You also need to monitor or update the software and machinery, so you'll probably want some kind of internal network. But can other things than the control systems connect to that network? Then you're screwed, unless you can absolutely guarantee that e.g. a laptop connected to the same network can't be compromised/transported out of the facility.
Iran's SCADA controllers were not connected to the Internet when they got owned by Stuxnet. They were just connected to a network with a laptop with a USB port.

So keep those off the Internet, and then pass whatever legislation and executive orders they want for those networks, and leave the Internet alone. Of course the reality is this executive order is going to have many "gotchas" hidden in it, to give the executive more power over the Internet, and we probably won't learn about them until it's too late.
