Is the new panel in the same building as the service, or where it's being fed from?

It is in the same building.

What do you mean shown with the feeder? It looks like a separate conduit with only a GEC from the panel to the service.

Then you don't need a GEC for that panel. The EGC ran with the feeder is all that is required.
I ASSuMEd the raceway coming in the top was the feeder even though it only shows the EGC.
IF the new panel is being fed from the existing panel and they both in the same building you only need a properly sized feeder to the new panel with an EGC complying with 250.122, 250.118
No GEC is required.
(The #8 would be correct for an EGC on a 100 amp feeder but not required if the feeder raceway meets 250.118)

Everyone agrees the GEC is not required but it is permitted to run a GEC from the panel as shown in the drawing.

Got it and thank you. Where in the NEC does it refer to this not needed?

The NEC doesn't say when it is not needed but will tell you when a GEC for a sub panel is needed. 250.32.
