§ 10.450   Geographic targeting.

   Link to an amendment published at  83 FR 8623 , February 28, 2018.

   This section establishes minimum requirements for the geographic
   targeting of Alert Messages.

   (a) A Participating CMS Provider will determine which of its network
   facilities, elements, and locations will be used to geographically
   target Alert Messages. A Participating CMS Provider must transmit any
   Alert Message that is specified by a geocode, circle, or polygon to an
   area that best approximates the specified geocode, circle, or polygon.
   If, however, the Participating CMS Provider cannot broadcast the Alert
   Message to an area that best approximates the specified geocode,
   circle, or polygon, a Participating CMS Provider may transmit an Alert
   Message to an area not larger than the propagation area of a single
   transmission site.

   (b) Upon request from an emergency management agency, a Participating
   CMS Provider will disclose information regarding their capabilities for
   geo-targeting Alert Messages. A Participating CMS Provider is only
   required to disclose this information to an emergency management agency
   insofar as it would pertain to Alert Messages initiated by that
   emergency management agency, and only so long as the emergency
   management agency offers confidentiality protection at least equal to
   that provided by the federal FOIA.
