   ^1Unlimited hours of use from December 15 to April 1 and day only from April
   1 to December 15. Harmful interference must not be caused to any station in
   the Great Lakes region.

   ^2In the Great Lakes region 2206 kHz is not available for transmission to
   U.S. ships except in the case of distress. U.S. coast stations in the Great
   Lakes area may use 2514, 2550 and 2582 kHz on a shared basis with coast
   stations of Canada. Except in the case of distress, the frequency 2550 kHz
   must not be used for transmission to ship stations of Canada since the
   associated ship station transmit frequency 2158 kHz is not available to
   Canadian ship stations for transmission and 2582 kHz must not be used for
   public  correspondence  transmissions  to U.S. ship stations since the
   associated ship transmit frequency 2206 kHz is not available to U.S. ship
   stations for transmissions except in the case of distress.

   ^3Limited to a peak envelope power of 150 watts.

   ^4Harmful  interference must not be caused to any coast station in the
   Caribbean region.

   ^5But see section 80.373(c)(3) of this chapter.

   (b) Working frequencies in the 4000-27500 kHz band. This paragraph describes
   the working carrier frequencies in the 4000-27500 kHz band. With respect to
   frequencies that are assignable in more than one geographical area, once the
   frequency  is assigned to one licensee, any subsequent license will be
   authorized  on a secondary, non-interference basis with respect to the
   incumbent license's existing operation. If the first licensee later seeks
   authorization  to  operate  in  an  additional  geographic  area, such
   authorization  will be on a secondary, non-interference basis to other
   co-channel licensees.

   (1) The following table specifies the carrier frequencies available for
   assignment  to  public coast stations. The paired ship frequencies are
   available  for use by authorized ship stations. The specific frequency
   assignment available to public coast stations for a particular geographic
   area is indicated by an “x” under the appropriate column. The allotment
   areas are in accordance with the “Standard Defined Areas” as identified in
   the  International Radio Regulations, Appendix 25 Planning System, and
   indicated in the preface to the International Frequency List (IFL).

   (2) The following table specifies the non-paired carrier frequencies that
   are  available  for  assignment  to  public coast stations for simplex
   operations. These frequencies are available for use by authorized ship
   stations  for  transmissions  to  coast stations (simplex operations).
   Assignments on these frequencies must accept interference. They are shared
   with government users and are considered “common use” frequencies under the
   international Radio Regulations. They cannot be notified for inclusion in
   the Master International Frequency Register, which provides stations with
   interference protection, but may be listed in the international List of
   Coast Stations. (See Radio Regulation No. 1220 and Recommendation 304.)

   (Channel 25) is not available for assignment under part 80.

   (ii) Service areas in the marine VHF 156-162 MHz band are VHF Public Coast
   Service Areas (VPCSAs). As listed in the table in this paragraph, VPCSAs are
   based on, and composed of one or more of, the U.S. Department of Commerce's
   172 Economic Areas (EAs). See  60 FR 13114  (March 10, 1995). In addition, the
   Commission shall treat Guam and the Northern Mariana Islands, Puerto Rico
   and the United States Virgin Islands, American Samoa, and the Gulf of Mexico
   as EA-like areas, and has assigned them EA numbers 173-176, respectively.
   Maps of the EAs and VPCSAs are available for public inspection and copying
   at  the FCC Public Reference Room, Room CY-A257, 445 12th Street, SW.,
   Washington, DC 20554, 1-888-225-5322. In addition to the EAs listed in the
   table in this paragraph, each VPCSA also includes the adjacent waters under
   the jurisdiction of the United States. In VPCSAs 10-42, the working carrier
   frequency pair 157.250 MHz/161.850 MHz (Channel 25) is not available for
   assignment under part 80.

   (iii) Subject to paragraph (c)(3) of this section, each licensee may also
   operate  on 12.5 kHz offset frequencies in areas where the licensee is
   authorized on both frequencies adjacent to the offset frequency, and in
   areas where the licensee on the other side of the offset frequency consents
   to the licensee's use of the adjacent offset frequency. Coordination with
   Canada is required for offset operations under any circumstance in which
   operations  on  either  adjoining  25  kHz  channel would require such
   coordination. See § 80.57 of this part.

   (2) Any recovered channel pairs will revert automatically to the holder of
   the  VPCSA license within which such channels are included, except the
   channel pairs listed in the table in paragraph (c)(1)(i) of this section.
   Those channel pairs, and any channel pairs recovered where there is no VPCSA
   licensee, will be retained by the Commission for future licensing.

   (e) Canada/U.S.A. channeling arrangement frequencies. The VHF frequencies
   assignable to ship and coast stations in the State of Washington and their
   usage limitations pursuant to the Canada/U.S.A. channeling arrangement are
   described in subpart B of this part.

   (4) Subject to the requirements of § 1.924 of this chapter and § 80.21, each
   VPCSA  licensee  may place stations anywhere within its region without
   obtaining prior Commission approval provided:

   (i)  It  provides to co-channel coast station incumbent licensees, and
   incumbent Private Land Mobile Radio licensees authorized under part 90 of
   this chapter on a primary basis, protection as defined in subpart P of this
   part. VPCSA licensees that share a common border may either distribute the
   available frequencies upon mutual agreement or request that the Commission
   assign frequencies along the common border.

   (ii) The locations and/or technical parameters of the transmitters are such
   that individual coordination of the channel assignment(s) with a foreign
   administration, under applicable international agreements and rules in this
   part, is not required.

   (iii) For any construction or alteration that would exceed the requirements
   of § 17.7 of this chapter, licensees must notify the appropriate Regional
   Office of the Federal Aviation Administration (FAA Form 7460-1) and file a
   request for antenna height clearance and obstruction marking and lighting
   specifications (FCC Form 854) with the FCC, Attn: Information Processing
   Branch, 1270 Fairfield Rd., Gettysburg, PA 17325-7245.

   (iv) The transmitters must not have a significant environmental effect as
   defined by § § 1.1301 through 1.1319 of this chapter.

   (d) Working frequencies in the Mississippi River System. The Mississippi
   River System includes the Mississippi River and connecting navigable waters
   other than the Great Lakes. The following simplex frequencies are available
   for assignment to public coast stations serving the Mississippi River System
   for  radiotelephony communications. These simplex frequencies also are
