Sec.  21.41   Special processing of applications for minor facility
modifications.

   

   (a) Unless an applicant is notified to the contrary by the Commission,
   as of the twenty-first day following the date of public notice, any
   application that meets the requirements of paragraph (b) of this
   section and proposes only the change specified in paragraph (c) of
   this section shall be deemed to have been authorized by the
   Commission.

   (b) An application may be considered under the procedures of this
   section only if:

   (1) It is in the Multipoint Distribution Service;

   (2) The cumulative effect of all such applications made within any 60
   days period does not exceed the appropriate values prescribed by
   paragraph (c) of this section;

   (3) The facilities to be modified are not located within 56.3
   kilometers (35 miles) of the Canadian or Mexican border;

   (4) It is acceptable for filing, is consistent with all of the
   Commission's rules, and does not involve a waiver request;

   (5) It specifically requests consideration pursuant to this section;

   (6) Frequency notification procedures are complied with and a copy of
   the application has been served on those who also were served under
   Sec. 21.902; and

   (7) In the Multipoint Distribution Service, the modified facility
   would not produce a power flux density that exceeds -73 dBW/m 2 ,
   pursuant to Sec. Sec. 21.902 and 21.939 at locations on the boundaries of
   protected service areas to which there is an unobstructed signal path.

   (c) The modifications that may be authorized under the procedures of
   this section are:

   (1) Changes in a transmitter and existing transmitter operating
   characteristics, or protective configuration of transmitter, provided
   that:

   (i) In the Multipoint Distribution Service, any increase in EIRP is
   one and one-half dB or less over the previously-authorized power
   value; or

   (ii) The necessary bandwidth is not increased by more than 10% of the
   previously authorized necessary bandwidth.

   (2) Changes in the height of an antenna, provided that:

   (i) In Multipoint Distribution Service, any increase in antenna height
   is less than 3.0 meters above the previously authorized height; and

   (ii) The overall height of the antenna structure is not increased as a
   result of the antenna extending above the height of the previously
   authorized structure, except when the new height of the antenna
   structure is 6.1 meters or less (above ground or man-made structure,
   as appropriate) after the change is made.

   (3) Change in the geographical coordinates of a transmit station by
   ten seconds or less of latitude, longitude or both, provided that when
   notice to the FAA of proposed construction is required by part 17 of
   this chapter for antenna structure at the previously authorized
   coordinates (or will be required at the new location) the applicant
   must comply with the provisions of Sec. 21.15(d).

   (d) Upon grant of an application under the procedure of this section
   and at such time that construction begins, the applicant must keep a
   complete copy of the application (including the filing date) with the
   station license if construction is commenced prior to the receipt of
   the authorization.
