Further, prior to constructing or installing any wireless communications facility, the applicant must submit financial security in an amount sufficient to cover the cost disassembly, demolition and removal of the wireless communications facility. The form of the financial security shall be of a type described in § 509 of the Pennsylvania Municipalities Planning Code, 53 Pa.C.S.A. § 10509(c), including, but not limited to, federal or commonwealth chartered lending institution irrevocable letters of credit, restrictive or escrow accounts in such lending institutions, as well as bonds. Approval of the type of financial security to be submitted shall be determined by the Board of Supervisors, however, approval of the form of security and of the provisions thereof, (e.g., the language of a bond) shall not be unreasonably withheld. The amount of financial security shall be determined by the Board of Supervisors, based upon information submitted by the applicant and reviewed by either the Township Engineer or other qualified consultant. In the event of a dispute concerning the appropriate amount of financial security, the Township Engineer and the applicant shall select a qualified third party to arbitrate the dispute informally and submit a determination to the Board of Supervisors; the amount of financial security determined by the neutral third party shall be binding. The financial security may be utilized for the disassembly, demolition, and removal of any wireless communications facility, in the event that the facility is either: (a) not properly maintained; (b) abandoned; or (c) not used for a period of six months or longer. The financial security shall be so utilized after 30 days advance written notice is forwarded by United States mail or private courier service (e.g., Federal Express, United Parcel Service) to any address provided by the applicant as part of the submission of an application for zoning or municipal or other building authorization or to any other address provided by applicant for the purposes of the receipt of notice under this provision. The bond or other security will be released to the applicant promptly upon the expiration of the lease, license, or other permission/authorization to make use of the subject property for the maintenance of a wireless communication facility.
