The central office permit manager shall be responsible for the issuance of all districtwide permits. The Department may authorize districtwide permits covering multiple districts. “Existing structure” means any structure that is installed or approved for installation at the time a wireless services provider or wireless infrastructure provider provides notice to a locality or the Department of an agreement with the owner of the structure to co-locate equipment on that structure. “Existing structure” includes any structure that is currently supporting, designed to support, or capable of supporting the attachment of wireless facilities, including towers, buildings, utility poles, light poles, flag poles, signs, and water towers. “Micro-wireless facility” means a small cell facility that is not larger in dimension than 24 inches in length, 15 inches in width, and 12 inches in height and that has an exterior antenna, if any, not longer than 11 inches. “Small cell facility” means a wireless facility that meets both of the following qualifications: (i) each antenna is located inside an enclosure of no more than six cubic feet in volume, or, in the case of an antenna that has exposed elements, the antenna and all of its exposed elements could fit within an imaginary enclosure of no more than six cubic feet and (ii) all other wireless equipment associated with the facility has a cumulative volume of no more than 28 cubic feet, or such higher limit as is established by the Federal Communications Commission. The following types of associated equipment are not included in the calculation of equipment volume: electric meter, concealment, telecommunications demarcation boxes, ground-based enclosures, back-up power systems, grounding equipment, power transfer switches, cut-off switches, and vertical cable runs for the connection of power and other services. “Utility pole” means a structure owned, operated, or owned and operated by a public utility, local government, or the Commonwealth that is designed specifically for and used to carry lines, cables, or wires for communications, cable television, or electricity. “Water tower” means a water storage tank, or a standpipe or an elevated tank situated on a support structure, originally constructed for use as a reservoir or facility to store or deliver water. “Wireless facility” means equipment at a fixed location that enables wireless services between user equipment and a communications network, including (i) equipment associated with wireless services, such as private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services, such as microwave backhaul, and (ii) radio transceivers, antennas, coaxial, or fiber-optic cable, regular and backup power supplies, and comparable equipment, regardless of technological configuration. “Wireless infrastructure provider” means any person, including a person authorized to provide telecommunications service in the state, that builds or installs transmission equipment, wireless facilities, or wireless support structures, but that is not a wireless services provider. “Wireless services” means (i) “personal wireless services” as defined in 47 U.S.C. § 332(c)(7)(C)(i); (ii) “personal wireless service facilities” as defined in 47 U.S.C. § 332(c)(7)(C)(ii), including commercial mobile services as defined in 47 U.S.C. § 332(d), provided to personal mobile communication devices through wireless facilities; and (iii) any other fixed or mobile wireless service, using licensed or unlicensed spectrum, provided using wireless facilities. “Wireless services provider” means a provider of wireless services. “Wireless support structure” means a freestanding structure, such as a monopole, tower, either guyed or self-supporting, or suitable existing structure or alternative structure designed to support or capable of supporting wireless facilities. “Wireless support structure” does not include any telephone or electrical utility pole or any tower used for the distribution or transmission of electrical service.
