Sec.  23.28   Special temporary authorization.

   (a) Requests for special temporary authority must be accompanied by a
   showing that interference will not be caused to the fixed public or fixed
   public press service for which the station is primarily licensed; and, in
   addition, such requests must be accompanied by the following:

   (1) A statement of the call signs, location, and frequencies of the
   transmitting station; The call signs, location, and frequencies of the
   received station; and the type or types of emission to be employed by both
   stations.

   (2) A statement as to whether the frequencies are to be used for contact
   control purposes only.

   (3) A statement of the period for which the temporary authority is desired.

   (4) A statement describing the service which is to be rendered.

   (b) Temporary authorizations of operation not to exceed 180 days may be
   granted under the standards of section 309(f) of the Communications Act
   where extraordinary circumstances so require. Extensions of the temporary
   authorizations for a period of 180 days may also be granted, but the renewal
   applicant bears a heavy burden to show that extraordinary circumstances
   warrant such an extension.

   (c) Each application proposing construction of one or more new antenna
   structures or alteration of the overall height of one or more existing
   antenna structures, where FAA notification prior to such construction or
   alteration is required by part 17 of this chapter, must include the FCC
   Antenna Structure Registration Number(s) for the affected structure(s). If
   no such number has been assigned at the time the application(s) is filed,
   the applicant must state in the application whether the owner has notified
   the FAA of the proposed construction or alteration and applied to the FCC
   for an Antenna Structure Registration Number in accordance with part 17 of
   this chapter. Applications proposing construction of one or more new antenna
   structures or alteration of the overall height of one or more existing
   antenna structures, where FAA notification prior to such construction or
   alteration is not required by part 17 of this chapter, must indicate such
   and, unless the structure is 6.10-meters or less above ground level (AGL),
   must contain a statement explaining why FAA notification is not required.
