If the grounding electrode conductor is #4 or smaller, it may require protection. See 250-64(b). If the ground rod was an 8' rod, it must be completely below grade. See 250-52(c). If you didn't drive 2 rods or use a ground resistance tester to verify compliance with 250-56, the inspector should have also told you to add a second ground rod.
