Grounding electrode conductor ran with other conductors

[tim89s]

I am coming out of a fused disconnect going approx 250',via GRC, to a transformer. The closest grounding electrode for the transformer is located near the disconnect supplying the transformer. One of my questions is can I run the grounding electrode conductor in the same raceway as the conductors feeding the transformer? If I wanted a equipment ground in the pipe would I have to pull a seperate wire than the grounding electrode conductor? Last question, assuming the above can be done, wound I bond the conduit at both ends using a supply side equipment bonding jumper according to 250.92A?

Thank you
Tim

Tim is this from one building to another or is that 250' all in the same building.

If it is all one building does it have a steel frame?

It is all one building and does not have a steel frame.

My gut says you can not run them together but I can't find a code section that backs that up.

Yes, I believe you can.

Yes, I believe you would.

I would say yes, both ends of the raceway would need to be bonded to the GEC, but not by the reference you gave. A seperately derived system is not a "service."

250.30(A)(5) requires that the GEC for an SDS be installed according to 250.64(A), (B), (C) and (E). 250.64(E) requires bonding on both ends of the raceway.

Ditto. I'm thinking there isn't a section prohibiting it.

Edit to add: 230.7, exception 1 seems to indicate that GECs and bonding jumpers can share conduits with other conductors, and in that particular case, even service conductors.

I'm thinking I have been drawing a mental parallel for GECs and service conductors, in terms of seperation from other conductors. In my head, a GEC is kind of sacred, and deserves it's own conduit, like service conductors. But I don't see a "230.7-like" section for GECs and bonding jumpers.
