§  1.30000   Purpose.

   This rule part protects the operations of AM broadcast stations from
   nearby tower construction that may distort the AM antenna patterns. All
   parties holding or applying for Commission authorizations that propose
   to construct or make a significant modification to an antenna tower or
   support structure in the immediate vicinity of an AM antenna, or
   propose to install an antenna on an AM tower, are responsible for
   completing the analysis and notice process described in this subpart,
   and for taking any measures necessary to correct disturbances of the AM
   radiation pattern, if such disturbances occur as a result of the tower
   construction or modification or as a result of the installation of an
   antenna on an AM tower. In the event these processes are not completed
   before an antenna structure is constructed, any holder of or applicant
   for a Commission authorization is responsible for completing these
   processes before locating or proposing to locate an antenna on the
   structure, as described in this subpart.
