Where is it mentioned that a 10' RMC or IMC is required at both ends for a C1D1 area for fuel. I do find in exception 2 that the last 24'' of conduit can be rigid as long as its 2' deep and conduit finish grade or am I wrong to say. What if a portion of the conduit runs under asphalt or grass a portion of the way? I tried searching my first question but cant find it then I ran into second. For informational use only.
