A Tower existing prior to the effective date of this by-law, which was in compliance with the town's zoning regulations immediately prior to the effective date of this by-law, may continue in existence as a non-conforming structure. Such non-conforming Towers and Lattice Type Structures may be modified or demolished and rebuilt without complying with any of the additional requirements of this Section, except for Sections 7.5.7, "Separation or Buffer Requirements," 7.5.18, "Certification and Inspections," and 7.5.19, "Maintenance," provided: a. The Tower or Lattice Type Structure is being modified or demolished and rebuilt for the sole purpose of accommodating, within six (6) months of the completion of the modification or rebuild, additional telecommunications facilities comparable in weight, size, and surface area to the discrete operating telecommunications facilities of any person currently installed on the tower. b. An application for a special permit is made to the board of appeals which shall have the authority to issue a special permit after a formal hearing. The grant of a special permit pursuant to this section allowing the modification or demolition and rebuild of an existing non-conforming tower shall not be considered a determination that the modified or demolished and rebuilt tower is conforming. c. The height of the modified or rebuilt Tower or Lattice Type Structure and telecommunications facilities attached thereto do not exceed the maximum height allowed under this by-law.
