   may be the licensee of a similar station at another location or may
   obtain communication service under a mutual agreement from the licensee
   of any station in the Public Safety Pool or any other station which is
   authorized to communicate with the fixed station.

   (xi) A communications common carrier operating communications circuits
   that normally carry essential communication of such a nature that their
   disruption would endanger life or public property is eligible to hold
   authorizations for standby radio facilities for the transmission of
   messages only during periods when the normal circuits are inoperative
   due to circumstances beyond the control of the user. During such
   periods the radio facilities may be used to transmit any communication
   which would be carried by the regular circuit. Initial applications for
   authorization to operate a standby radio facility must include a
   statement describing radio communication facilities desired, the
   proposed method of operation, a description of the messages normally
   being carried, and an explanation of how their disruption will endanger
   life or public property.

   (xii) Communications common carriers for radio facilities to be used in
   effecting expeditious repairs to interruption of public communications
   facilities where such interruptions have resulted in disabling
   intercity circuits or service to a multiplicity of subscribers in a
   general area. Stations authorized under this section may be used only
   when no other means of communication is readily available, for the
   transmission of messages relating to the safety of life and property
   and messages which are necessary for the efficient restoration of the
   public communication facilities which have been disrupted.

   (xiii) Persons or entities engaged in the provision of basic or
   advanced life support services on an ongoing basis are eligible to hold
   authorization to operate stations for transmission of communications
   essential for the delivery or rendition of emergency medical services

   (g) Former public correspondence working channel in the maritime VHF
   (156-162 MHz) band allocated for public safety use in 33 inland
   Economic Areas. (1) We define service areas in the marine VHF (156-162
   MHz) band by forty-two geographic areas called VHF Public Coast Service
   Areas (VPCSAs). See § 80.371(c)(1)(ii) of this chapter (Public
   correspondence frequencies). VPCSAs are based on, and composed of one
   or more of, the U.S. Department of Commerce's 172 Economic Areas (EAs).
   See 60 Fed Reg. 13114 (Mar. 10, 1995). You may inspect and copy maps of
   the EAs and VPCSAs at the FCC Reference Center, Room CY A-257, 445 12th
   St., SW., Washington, DC 20554. These maps and data are also available
   on the FCC website at http://www.fcc.gov/oet/info/maps/areas/. We
   number public correspondence channels in the maritime VHF (156-162 MHz)
   band as channels 24 to 28 and channels 84 to 88. Each channel number
   represents a channel pair. See § 80.371(c) of this chapter.

   (2) In VHF Public Coast Service Areas (VPCSAs) 10-42, the duplex
   channel pair 157.250 MHz/161.850 MHz (VHF Maritime Channel 25) is
   allocated for public safety use by entities eligible for licensing
   under paragraph (a) of this section, and is designated primarily for
   the purpose of interoperability communications. See 47 CFR
   80.371(c)(1)(ii) for the definitions of VPCSAs.

   (i) The channel pair 157.250 MHz/161.850 MHz was formerly allocated and
   assigned (under § 80.371(c) (1997) of this chapter) as a public
   correspondence working channel in the maritime VHF 156-162 MHz band,
   and was also shared (under former § 90.283 (1997) of this chapter) with
   private land mobile stations, including grandfathered public safety
   licensees. Thus, there are grandfathered licensees nationwide (maritime
   and private land mobile radio stations, including by rule waiver)
   operating on this channel both inside and outside of VPCSAs 10-42.

   (ii) The channel pairs 157.225 MHz/161.825 MHz and 157.275 MHz/161.875
   MHz were formerly allocated and assigned under this section as public
   safety interoperability channels but were reallocated for assignment as
   VHF public coast station channels under § 80.371(c) of this chapter.
   Public safety operations licensed on these channels as of March 2, 2009
   or licensed pursuant to an application filed prior to September 19,
   2008, may remain authorized to operate on the channels on a primary
   basis until March 2, 2024.

   (3) All applicants and licensees under this paragraph must comply with
   the relevant technical sections under this part unless otherwise stated
   in this paragraph (g) of this section using the following standards and
   procedures:

   (i) Provide evidence of frequency coordination in accordance with
   § 90.175. Public safety coordinators except the Special Emergency
   Coordinator are certified to coordinate applications for the channel
   pair 157.250 MHz/161.850 MHz (i.e., letter symbol PX under paragraph
   (c)(2) of this section).

   (ii) Station power, as measured at the output terminals of the
   transmitter, must not exceed 50 Watts for base stations and 20 Watts
   for mobile stations, except in accordance with the provisions of
   paragraph (g)(3)(vi) of this section. Antenna height (HAAT) must not
   exceed 122 meters (400 feet) for base stations and 4.5 meters (15 feet)
   for mobile stations, except in accordance with paragraph (g)(3)(vi) of
   this section. Antenna height (HAAT) must not exceed 122 meters (400
   feet) for base stations and 4.5 meters (15 feet) for mobile stations,
   except in accordance with paragraph (g)(3)(vi) of this section. Such
   base and mobile channels shall not be operated on board aircraft in
   flight.

   (iii) Frequency protection must be provided to other stations in
   accordance with the following guidelines for each channel and for each
   area and adjacent area:

   (A) Protect coast stations licensed prior to July 6, 1998, by the
   required separations shown in Table C below.

   (B) Protect stations described in paragraph (g)(2)(i) of this section,
   by frequency coordination in accordance § 90.175 of this part.

   (C) Protect public safety stations granted under paragraph (g) of this
   section by frequency coordination in accordance with § 90.175 of this
   part.

   (D) Where the Public safety designated channel is not a Public safety
   designated channel in an adjacent VPCSA: Applicants shall engineer base
   stations such that the maximum signal strength at the boundary of the
   adjacent VPCSA does not exceed 5dBµV/m.

   (iv) The following table, along with the antenna height (HAAT) and
   power (ERP), must be used to determine the minimum separation required
   between proposed base stations and co-channel public coast stations
   licensed prior to July 6, 1998 under part 80 of this chapter.
   Applicants whose exact ERP or HAAT are not reflected in the table must
   use the next highest figure shown.

   (v) In the event of interference, the Commission may require, without a
   hearing, licensees of base stations authorized under this section that
   are located within 241 kilometers (150 miles) of a co-channel public
   coast, I/LT, or grandfathered public safety station licensed prior to
   July 6, 1998, or an international border, to reduce power, decrease
   antenna height, and/or install directional antennas.

   Mobile stations must be operated only within radio range of their
   associated base station.

   (vi) Applicants seeking to be licensed for stations exceeding the
   power/antenna height limits of the table in paragraph (g)(3)(iv) of
   this section must request a waiver of that paragraph and must submit
   with their application an interference analysis, based upon an
   appropriate, generally-accepted terrain-based propagation model, that
   shows that co-channel protected entities, described in paragraph
   (g)(3)(iii) of this section, would receive the same or greater
   interference protection than the relevant criteria outlined in
   paragraph (g)(3)(iii) of this section.

   (h) Spectrum leasing arrangements. Notwithstanding any other provisions
   of this section to the contrary, licensees in the Public Safety Radio
   Services (see part 90, subpart B) may enter into spectrum leasing
   arrangements (see part 1, subpart X of this chapter) with entities
   providing communications in support of public safety operations.

   (i) Nationwide interoperability channels. The nationwide
   interoperability and mutual aid channels are listed below for the VHF,
   (including 220-222 MHz), UHF, 700 MHz and 800 MHz bands. (See
   § § 90.20(d)(80), 90.531(b)(1), 90.617(a)(1) and 90.720). Any Part 90
   public safety eligible entity holding a Part 90 license may operate
   hand-held and vehicular mobile units on these channels without needing
   a separate authorization. Base stations or control stations operating
   on these channels must be licensed separately: Encryption may not be
   used on any of the interoperability or mutual aid calling channels.
