   station  at  any  establishment  in  an  isolated  area shall make the
   communication facilities of such station available at no charge to any
   person desiring the transmission of any communication permitted by paragraph
   (a) of this section.

   ( 2 ) For the purpose of providing the communications link desired the
   licensee of a station at an establishment in an isolated area either 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

   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 for the provision of
   basic  or  advanced life support. Applications submitted by persons or
   organizations (governmental or otherwise) other than the governmental body
   having jurisdiction over the state's emergency medical service plans must be
   accompanied  by  a  statement prepared by the governmental body having
   jurisdiction over the state's emergency medical services plan indicating
   that the applicant is included in the state's emergency plan or otherwise
   supporting the application.

   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., S.W., 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
    Sec. 80.371(c) of this chapter.

   (2) We allocated two contiguous 25 kHz public correspondence channels in the
   maritime VHF (156–162 MHz) band for public safety use in 33 VPCSAs that are
   not near major waterways. These 33 VPCSAs are located in an inland region
   stretching from the western Great Plains to eastern California and Oregon.
   Each of these 33 inland VPCSAs corresponds to a single EA. Channel pairs 25,
   84, and 85 are paired 25 kHz bandwidth channels as set forth in paragraph
   (g)(2)(i) Table A of this section. In each of the 33 inland VPCSAs/EAs
   listed in paragraph (g)(2)(i)Table B of this section, two of these three
   channel pairs are allocated for public safety use by entities eligible for
   licensing under paragraph (a) of this section.

   (3) The channels pairs set forth in Table B paragraph (g)(2)(ii) of this
   section  are  designated primarily for the purpose of interoperability
   communication.

   (4) Channel pairs 25, 84, and 85 as listed in Table B paragraph (g)(2)(ii)
   of this section were formerly allocated and assigned (under  Sec. 80.371(c)
   (1997) of this chapter) as public correspondence working channels in the
   maritime VHF 156–162 MHz band; these channels were also shared (under former
    Sec. 90.283 (1997) of this chapter) with private land radio 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 these channels both inside
   and outside of the 33 EAs listed in Table B paragraph (g)(2)(ii) of this
   section

   (5) 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  Sec. 90.175.
   Public safety coordinators except the Special Emergency Coordinator are
   certified to coordinate applications for the channels pairs set forth in
   Table B paragraph (g)(2)(ii) ( 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)(5)(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)(5)(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)(5)(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)(4) of this section, by
   frequency coordination in accordance with  Sec. 90.175 of this part.

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

   (D)  Where the Public safety designated channel is not a Public Safety
   designated  channel  in an adjacent EA: Applicants shall engineer base
   stations  such that the maximum signal strength at the boundary of the
   adjacent EA does not exceed 5 dB V/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)(5)(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)(5)(iii) of this
   section, would receive the same or greater interference protection than the
   relevant criteria outlined in paragraph (g)(5)(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.
