IMO, 13D does not reference NFPA 20. Therefore, there is no indication of a need for a reliable power source. Would it be a prudent decision to have backup power? IMO yes. Is it required? I don't believe so.

They propose to install a pump and tank system. Would a back up power supply be required for this? I have never been asked about it but can’t find much that addresses it.
