The FCC has the authority and ability to levey very large fines and have 
done so in cases where their demands were disregarded. I believe the most 
recent was down in Texas.

I've lived about a half mile from one of these lines for over 23 years. I've 
never heard it on 160 through 440 which I can't say about the medium voltage 
lines around here. Those have had a number of occasions where they were 
relaly bad, but electric fences have been worse.  The worst has been an 
intermittent broad band noise that starts (usually) just above 20 meters and 
extends above 6-meters. It's to the SE and may come on abruptly and rise to 
well over S-9, but usually fades away slowly after an hour or so. OTOH it's 
sometimes on for hours.  However, every time we've gone hunting for it the 
thing disappears.
