Yes, thanks...too long of a day.*Not with an EGC... but rather in the service disconnecting means with an MBJ (Main Bonding Jumper).
*EGC is required with the feeder to the building, because the grounded conductor is not bonded to either EGC or GEC at the building. In much older editions, an EGC was not required, but the grounded conductor was required to be bonded to both EGC or GEC at the building. An adequate ground fault current path is the reason.
I meant GEC in both of those cases.
