I repeat Hotline's post: this is a PoCo issue, they are the AHJ...check their standards.
The NEC does require protection from traffic- and that's it. PoCo standards typically tell you how many, how tall, sunk how deep, made how, painted what color, etc. They will also specify WHERE to place the bollards- can't have a bollard blocking line tool access, can we?

I have looked in the NEC, IEEE handbook, NESC handbook,in 40 years I have never seen it done, bollard bonding along with bonding the manhole cover, yet I am being told by a sub contractor for the DOE hired to do NEC inspections that these are both code violations. I would appreciate any input available.
