The applicant shall provide a performance bond and/or other assurances satisfactory to the appropriate Board having jurisdiction in a form approved by the Township Attorney that will cause the antennas, the supporting tower, the ancillary building enclosing related electronic equipment and all other related improvements to the land to be removed at no cost to the Township, when the antennae are no longer operative. Any communication facility not used for its intended and approved purpose for a period of 12 months shall be considered no longer operative and abandoned and shall be removed by the applicant or their assigns within 60 days thereof. If the use of the tower is 10% or less of its maximum permitted capacity, it shall be considered no longer operative and therefore abandoned.
