Jerry,
A couple questions.
Does the inspector test the resistance between the two ground rods or do they simply "ass""u""me" it meets current standard?
Is this "in contact with soil" from the NEC or from the former CoH code; because as far as the NEC should be concerned and if used to describe contact with the electrode it has a far more reaching meaning. If its CoH defined it’s probably just as arbitrarily disjointed as the majority of the rest of its codes.
From the Army Corps of Engineering and all other legitimate sources, Soil is a term used to describe the composition of the Earth that is not composed of a majority concentration H2O. Granite, Basalt, Lava, Clay and or Dirt are all just a few of the several forms of “Soil” thus soil is not solely used to describe Dirt though commonly confused as such. Technically speaking and though this may appear very strange: concrete is a product composed of soil and though not widely naturally occurring and rare as it may be in nature, it’s a naturally occurring soil also, just as glass is.
So the meaning of soil is diverse and I cannot believe that the NEC would not pay heed to establishing a given power load capacity that must be met, vs. mandating 2 mandatory ground rods in an arbitrary material, it simply seems a very irresponsibly formed code and not at all in the spirit of the NEC and more liken to some crazy wayward CoH code.
If it is NEC, then there has to be far more content in the subject.
E ho'a'o no i pau kuhihewa.
