   C.   The certification inspector shall determine the interior dimensions and liquid capacity of the septic tank.
   D.   The inspection shall be certified by a licensed plumber, septic system installer, or septic tank pumping company and shall be the responsibility of the property seller. Approved license types for certification inspectors include the Arizona Registrar of Contractors licenses L-37, L-41, L-77, A-12, C-37, C-41 and a liquid waste haulers license issued by the department.
