Does this rule apply for outdoor feeder transformer?
 
In terms of lightning protection, i think it's required particularly the code doesn't mention the distance of the transformer away from served building.
 
Even Though, can we play with POCO equipment?

So as I said, I hate this. This has been bugging me all day. What does this even mean? So I have my "regular" grounding electrodes/electrode system and grounding electrode conductor, and I have to add an addition grounding electrode conductor that connects to the grounded conductor at a different spot? It sounds like it could connect to a stand alone electrode if not close enough (whatever that would be) to trigger 250.50 or 250.58, otherwise it sould just be a second GEC connecting the same GES.
 
But still, it's required for feeder transformer.
