\1\ Unlimited 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.
\2\ In 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.
\3\ Limited to a peak envelope power of 150 watts.
\4\ Harmful interference must not be caused to any coast station in the
  Caribbean region.
\5\ But 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).

                                               Working Carrier Frequency Pairs
in the 4000-27500 kHz Band

   (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.)

\1\ For special assignment of frequencies in this band in certain areas
  of Washington State, the Great Lakes and the east coast of the United
  States pursuant to arrangements between the United States and Canada,
  see subpart B of this part.
\2\ The frequency pair 157.275/161.875 MHz is available on a primary
  basis to ship and public coast stations. In Alaska it is also
  available on a secondary basis to private mobile repeater stations.
\3\ Within 120 km (75 miles) of the United States/Canada border, in the
  area of the Puget Sound and the Strait of Juan de Fuca and its
  approaches, the frequency 157.425 MHz is available for use by ship
  stations for public correspondence communications only. One hundred
  twenty kilometers (75 miles) from the United States/Canada border
  157.425 MHz is available for intership and commercial communications.
  Outside the Puget Sound area and its approaches and the Great Lakes,
  157.425 MHz is available for communications between commercial fishing
  vessels and associated aircraft while engaged in commercial fishing
  activities.

   (ii) Service areas in the marine VHF 156–162 MHz band are VHF Public Coast
   Station 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. Except as shown in the table, the frequency pairs
   listed in paragraph (c)(1)(i) of this section are available for assignment
   to a single licensee in each of the VPCSAs listed in the table in this
   paragraph. 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.

   (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  Sec. 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)(ii) 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.

   (3) VPCSA licensees may not operate on Channel 228B (162.0125 MHz), which is
   available for use in the Coast Guard's Ports and Waterways Safety System
   (PAWSS)). In addition, within six months of the conclusion of the
   competitive bidding procedures to determine the licensees in each VPCSA, the
   U.S. Coast Guard shall submit to each licensee of VPCSAs 1–9 a plan
   specifying up to two narrowband channel pairs offset 12.5 kHz from the
   channels set forth in the table in paragraph (c)(1)(i) of this section, for
   use in the PAWSS. The final selection of the PAWSS channel pairs can be
   negotiated (if the VPCSA licensee objects to the Coast Guard proposal, it
   shall make a counterproposal within three months) and established by an
   agreement between the parties. All parties are required to negotiate in good
   faith. If no agreement is reached within one year of the date the Coast
   Guard submitted its plan, the Coast Guard may petition the Commission to
   select the channel pairs.

   (4) Subject to the requirements of  Sec. 1.924 of this chapter and  Sec. 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  Sec. 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  Sec.  Sec. 1.1301 through 1.1319 of this chapter.
