The following types of associated equipment are not included in the calculation of equipment volume: electric meter, concealment, telecommunications demarcation boxes, back-up power systems, grounding equipment, power transfer switches, cut-off switches, and vertical cable runs for the connection of power and other services. “Standard process project” means any project other than an administrative review-eligible project. “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 communications 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 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.
