also give details of the net result of any changes made to the tower or its appurtenances since the last inspection.

(3) The ANSI EIA/TIA 222 standards

The ANSI EIA/TIA 222 standards as adopted by the current NC Building Code shall apply to the addition of antennas or other appurtenances to telecommunication towers under the following conditions: (A) Additions to towers constructed prior to the effective date of this Ordinance, regardless of whether the additions are accounted for in the original design, shall comply with the ANSI EIA/TIA 222 standards as adopted by the current NC Building Code and the wind loading specified therein. Additions to towers constructed subsequent to the effective date of this Ordinance shall comply with standards set forth elsewhere in this Section. (B) If a structural analysis shows a tower does not comply with the appropriate ANSI EIA/TIA 222 standards as adopted by the current NC Building Code, the owner shall submit an application to the Planning Department with a plan to bring the tower into compliance within six months. The tower owner shall obtain all applicable permits for the work. For any existing antenna modification, replacement or upgrade, the applicant must, prior to making such modifications, submit the following: (1) A description of the proposed revisions to the antenna, including the element design, type and number, as well as changes in the number and/or size of any feed lines, from the base of the equipment cabinet to such antenna elements. (2) A signed statement from an RF Engineer, together with their qualifications, shall be incl uded representing the tower’s owner or owner’s agent that the radio frequency emissions comply with FCC standards for such emissions. The statement shall also certify that both individually and cumulatively, and with any other facilities located on or immediately adjacent to the proposed facility, the revised antenna complies with FCC standards. (3) A sealed structural analysis of the existing structure prepared by a registered Professional Engineer licensed by the State of North Carolina indicating that the existing tower as well as all existing and proposed appurtenances meets current NC Building Code requirements, including, but not limited to, wind loading and ANSI EIA/TIA 222 standards, for the tower.
