(1) Except as provided in subsections (2) and (3) of this section, the operation or erection of any tools, machinery, or equipment, or any part thereof capable of vertical, lateral, or swinging motion, or the handling or storage of any supplies, materials, or apparatus or the moving of any house or other building, or any part thereof, under, over, by, or near overhead high voltage conductors, shall be prohibited if, at any time during such operation or other manipulation, it is possible to bring such equipment, tools, materials, building, or any part thereof within ten feet of such overhead high voltage conductors, except where such high voltage conductors have been effectively guarded against danger from accidental contact, by any of the following:
(a) Erection of mechanical barriers to prevent physical contact with high voltage conductors;
(b) Deenergizing of the high voltage conductors and grounding where necessary; or
(c) Temporary relocation of overhead high voltage conductors.
(2) The minimum distance required by this section for cranes or other boom type equipment in transit with no load and with raiseable portions lowered shall be four feet.
(3) Nothing in sections 48-436 to 48-442 shall prohibit the moving of general farm equipment under high voltage conductors where clearances required by sections 48-436 to 48-442 are maintained.
(4) The activities performed as described in subdivisions (1)(a), (b), and (c) of this section shall be performed only by the owner or operator of the high voltage conductors unless written authorization has been obtained from such owner or operator. This subsection shall not be construed to apply to activities performed by an electric utility on high voltage conductors of another electric utility when the electric utilities have a written agreement (a) providing for joint use of poles or structures supporting the high voltage conductors of the electric utilities or (b) approving the nonowning electric utility's performance of the activities described in subdivisions (1)(a), (b), and (c) of this section on an ongoing basis on the owning or operating electric utility's high voltage conductors.
