Buried cables shall be at a depth of at least thirty-six (36) inches below grade or, if necessitated by onsite conditions, at a greater depth. Cables and lines located outside of the CSE system project site may:
(1) be located above ground; or
(2) in the case of cables or lines of up to thirty-four and one-half (34.5) kilovolts, be buried underground at:
(A) a depth of at least forty-eight (48) inches below grade, so as to not interfere with drainage tile or ditch repairs; or
