More Grounding Woes

Here is the second time it seems I have to include a ground wire for each circuit in a multi circuit conduit.

Equipment grounding conductors for branch circuit home runs shown on the drawings shall indicate an individual and separate ground conductor for that branch circuit which shall be terminated at the branch circuit panelboard, switchboard, or other distribution equipment. No sharing of equipment grounding conductors sized according to the size of the overcurrent device and NEC Table 250.122 shall be allowed.

My customer interprets this as multiple ground wires. What do you folks think?

More Ground Wires Please

I just found a first for my career. A specification for a school project in Kansas requires individual grounds in multi circuit homeruns. First it was no shared neutrals, and now it is no shared grounds. For this project, a 3 circuit homerun get 3 hots, 3 neutrals and 3 grounds.

Is this an upcoming code change?
