Don, if they had not included the word "level" it would have more strength as to meaning on dirt.
I know that the panels statement in rejecting the ROP did not include the word "level" but the article does and there is no errata changing it.
If the true intent is to be standing on dirt, what if we built a raised planter box 3' high and 4' wide around the whole house and filled it with dirt, is this a new grade since we can now stand in the dirt and use the receptacle?
What would be the logic behind the reason they would want a person to be physically standing in dirt to use this receptacle?
