One city inspector (who is no longer there) once asked for a 3rd ground rod to be driven. The reason? Installer used PVC between the meter & the service disconnect, thereby avoiding the need for a grounding bushing. Inspector knew there was supposed to be a grounding bushing installed and since there wasn't, the third ground rod made up for it.
Needless to say, in our state, there are no requirements to be an inspector for a municipality, if the city puts you in that job, you're "qualified."
