or within the time specified in its security program, of the discovery

approved by TSA, this written notification becomes a part of the airport 
security program for the duration of the changed condition(s).
    (d) For changed conditions expected to be 60 days or more duration, 
each airport operator must forward the information required in paragraph 
(b) of this section in the form of a proposed amendment to the airport 
operator's security program, as required under Sec. 1542.105. The 
request for an amendment must be made within 30 days of the discovery of 
the changed condition(s). TSA will respond to the request in accordance
