You make a good point Jim.  There's nothing I could find in the 
guidelines/standard aimed at operations below 30MHz.  

However, an EOC is a really just special Comm Site.  I wouldn't ignore industry 
recommendations for lightning protection and AC power safety based on the fact 
it's doesn't specify any standards for operations below 30 MHZ if they even 
exist.  Lightning is very broadbanded so anything put into place to deal with 
lightning will benefit the ham bands as well as commercial site operations.  If 
things are bonded and grounded properly, there's much less chance of creating 
other unexpected RF problems no matter what the frequency of operation.  

My rule for using R56 at ham shacks:  Look for special exception guidelines 
like 911 centers, roof mounted sites, etc, that may be similar to what your ham 
shack looks like in your home.  For an EOC, I'd look very closely at guidelines 
for 911 dispatch comm centers that must operate 24/7/365.

Does it pay attention to emissions below 30 MHz?
