This line going in where you can prove it or not. What you need to prove
is if there is noise that is costing them money buy having power leakage
to ground that no one is pay the bill for. Money is the only thing
company's like this understand. Profit loss is the approach to go.

Apparently, there are no hard-and-fast limits on RFI from power poles.
Only
that they be "engineered" properly. According to John, there are no
tests I
can perform to "prove" that they interfere with my radio. Can this be
true?
I have a HP spectrum analyser at my QTH. If there were a test set-up
that
demonstrates the interference, I might get some action around here.
Without
standards for comparison, I'm screwed! Anybody know of standards?
