Where in NEC 2008 does it state that a common grounding electrode conductor can be ran to a copper bar, for bonding other electrode bonding conductors? I know I've read it but now can not find it.
 
You refering to a terminal, bar, or bus? It is mentioned several times in 250. Don't hold me to it, I think somewhere around 250.24 (no book handy at the moment).
 
Found it! Section 250.64(F)(3). And it's a 1/4" by 2" minimum bar, not 2" by 4". My mistake.

That being said, would the grounding busbar in a feeder panel, for equipment grounding conductors, qualify as this 1/4" by 2" minimum busbar, if it is copper? Or would a totally seperate copper busbar have to installed, at an accessible location?
 
250.64(F)(3) Bonding jumper(s) from grounding electrode(s) shall
be permitted to be connected to an aluminum or copper
busbar not less than 6 mm ? 50 mm (1⁄4 in. ? 2 in.). The
busbar shall be securely fastened and shall be installed
in an accessible location. Connections shall be made by
a listed connector or by the exothermic welding process.
The grounding electrode conductor shall be permitted to
be run to the busbar. Where aluminum busbars are used,
the installation shall comply with 250.64(A).
 
According to section 250.24(D)...

The GEC shall be used to connect the equip. grounding conductors, service enclosures & grounded conductor to the grounding electrode.

So terminating all electrode bonding jumpers to a feeder panel equipment grounding conductor terminal bar...
Then installing the GEC from this egc terminal bar to the grounded conductor at the service disconnect...
would be code compliant, correct?
