Bob, I notice that when I count the posts I've made on this site plus the other sites you and I frequent, there are well over 1,000 of them. The only reason I bring that up is that I hope by now you know that I NEVER make up the code as I go, and in fact people that do really anger me.
I would require the 4-wire service because in my opinion a pole is not a structure. I'm not saying that to be a PITA, I'm saying that because I am in the business of enforcing the law. 90.4 says that I can waive a specific requirement unless there is an alternative that provides an equal amount of safety. Is there? I don't know...I'm not as well versed in theory as I wish I were.
As far as going over my head, you certainly could, but my boss has never allowed it. In my city I am the highest authority in electrical. I would much rather discuss it with the installer and perhaps one of us could walk away a wiser man (probably me). There is seldom need to go over my head. I think I'm a reasonable enough guy.
