Sec. 80.21  Supplemental information required.

    Applications for radio stations to be located within designated 
radio protection areas, radio stations with a proposed antenna structure 
which will require antenna markings, a new public coast stations 
proposing operations in the 156-162 MHz band and new ship stations on 
vessels not located in the United States must contain supplementary 
information as indicated in

[[Page 18]]

this section. Other supplemental information may be required by other 
rule sections of this part concerning particular maritime services.
    (a) To minimize harmful interference at the National Radio Astronomy 
Observatory site at Green Bank, Pocahontas County, WV, and at the Naval 
Radio Research Observatory site at Sugar Grove, Pendleton County, WV, an 
applicant for a new station authorization (other than mobile or 
temporary fixed), or for modification of an existing license to change 
the frequency, power, antenna location, height or directivity within the 
area bounded by 39 deg.15' N. on the north, 78 deg.30' W. on the east, 
37 deg.30' N. on the south and 80 deg.30' W. on the west, must, at the 
time of filing such application with the Commission, notify the 
Director, National Radio Astronomy Observatory, Attn: Interference 
Office, Post Office Box No. 2, Green Bank, WV 24944, in writing, of the 
geographical coordinates of the antenna, antenna height, antenna 
directivity if any, proposed frequency, type of emission, and power. The 
application must show the date notification was made to the Observatory. 
The Commission will allow twenty (20) days after receipt of the 
notification for comments or objections. If a timely objection is 
received, the Commission will consider the comments or objections and 
act appropriately.
    (b) Protection for Federal Communications Commission monitoring 
stations:
    (1) Geographical coordinates of FCC facilities which require 
protection are listed in Sec. 0.121(c) of this chapter. Applications for 
stations (except mobile stations) which will be located within 80 km (50 
miles) of the referenced coordinates are examined to determine extent of 
possible interference. A clause protecting the monitoring station may be 
added to the station license.
    (2) Prospective applicants of stations for which the calculated 
value of expected field strength exceeds 10 mV/m (-65.8 dBW/
m2) at the referenced coordinates, should consult with the 
FCC to determine if any protection is necessary. Write:

    Chief, Compliance and Information Bureau, Federal Communications 
Commission, Washington, DC 20554.

    (c) Each application for a new public coast station operating on 
frequencies in the band 156-162 MHz must include as supplementary 
information a chart, with supporting data, showing the service area 
contour computed in accordance with subpart P of this part.
    (d) Each application for a new public coast station operating on 
frequencies in the band 156-162 MHz to be located within the 
coordination boundaries of ``Arrangement ``A'' of the Canada/U.S.A. 
Frequency Coordination Agreement above 30 MHz'', must comply with the 
provisions of the ``Canada/U.S.A. Channeling Agreement for VHF Maritime, 
Public Correspondence'' as contained in Sec. 80.57.
    (e) An application for a new station on a vessel not located in the 
United States must include:
    (1) A statement that the vessel is not documented or otherwise 
registered by any foreign authority; and
    (2) A statement that the foreign authorities where the vessel is 
located will not or cannot license the vessel radio equipment, or that 
they do not object to the licensing of the equipment by the United 
States.
