(A)   No expansion of non-conforming use.  Towers that are constructed, and antennas that are installed, in accordance with the provisions of this chapter shall not be deemed to constitute the expansion of a non-conforming use or structure.
   (B)   Pre-existing towers.  Pre-existing towers shall be allowed to continue their usage as they presently exist.  Routine maintenance (including replacement with a new tower of like construction and height) shall be permitted on such pre-existing towers.  New construction other than routine maintenance on a pre-existing tower shall comply with the requirements of this chapter.
   (C)   Rebuilding damaged or destroyed non-conforming towers or antennas.  Notwithstanding § 159.19, bona fide non-conforming towers or antennas that are damaged or destroyed may be rebuilt without having to first obtain administrative approval or a special use permit and without having to meet the separation requirements specified in § 159.17(B)(4) and (B)(5).  The type, height and location of the tower on site shall be of the same type and intensity as the original facility approval. Building permits to rebuild the facility shall comply with the then applicable building codes and shall be obtained within 180 days from the date the facility is damaged or destroyed.  If no permit is obtained or if said permit expires, the tower or antenna shall be deemed abandoned as specified in § 159.10.
