Section 1542.105 - Approval and amendments(a)Initial approval of security program. Unless otherwise authorized by the designated official, each airport operator required to have a security program under this part must submit its initial proposed security program to the designated official for approval at least 90 days before the date any aircraft operator or foreign air carrier required to have a security program under part 1544 or part 1546 of this chapter is expected to begin operations. Such requests will be processed as follows:(1) The designated official, within 30 days after receiving the proposed security program, will either approve the program or give the airport operator written notice to modify the program to comply with the applicable requirements of this part.(2) The airport operator may either submit a modified security program to the designated official for approval, or petition the Administrator to reconsider the notice to modify within 30 days of receiving a notice to modify. A petition for reconsideration must be filed with the designated official.(3) The designated official, upon receipt of a petition for reconsideration, either amends or withdraws the notice, or transmits the petition, together with any pertinent information, to the Administrator for reconsideration. The Administrator disposes of the petition within 30 days of receipt by either directing the designated official to withdraw or amend the notice to modify, or by affirming the notice to modify.(b)Amendment requested by an airport operator. Except as provided in § 1542.103(c) , an airport operator may submit a request to the designated official to amend its security program, as follows:(1) The request for an amendment must be filed with the designated official at least 45 days before the date it proposes for the amendment to become effective, unless a shorter period is allowed by the designated official.(2) Within 30 days after receiving a proposed amendment, the designated official, in writing, either approves or denies the request to amend.(3) An amendment to a security program may be approved if the designated official determines that safety and the public interest will allow it, and the proposed amendment provides the level of security required under this part.(4) Within 30 days after receiving a denial, the airport operator may petition the Administrator to reconsider the denial.(5) Upon receipt of a petition for reconsideration, the designated official either approves the request to amend or transmits the petition within 30 days of receipt, together with any pertinent information, to the Administrator for reconsideration. The Administrator disposes of the petition within 30 days of receipt by either directing the designated official to approve the amendment or affirming the denial.(c)Amendment by TSA. If safety and the public interest require an amendment, the designated official may amend a security program as follows:(1) The designated official sends to the airport operator a notice, in writing, of the proposed amendment, fixing a period of not less than 30 days within which the airport operator may submit written information, views, and arguments on the amendment.(2) After considering all relevant material, the designated official notifies the airport operator of any amendment adopted or rescinds the notice. If the amendment is adopted, it becomes effective not less than 30 days after the airport operator receives the notice of amendment, unless the airport operator petitions the Administrator to reconsider no later than 15 days before the effective date of the amendment. The airport operator must send the petition for reconsideration to the designated official. A timely petition for reconsideration stays the effective date of the amendment.(3) Upon receipt of a petition for reconsideration, the designated official either amends or withdraws the notice, or transmits the petition, together with any pertinent information to the Administrator for reconsideration. The Administrator disposes of the petition within 30 days of receipt by either directing the designated official to withdraw or amend the amendment, or by affirming the amendment.(d)Emergency amendments. Notwithstanding paragraph (c) of this section, if the designated official finds that there is an emergency requiring immediate action with respect to safety and security in air transportation or in air commerce that makes procedures in this section contrary to the public interest, the designated official may issue an amendment, effective without stay on the date the airport operator receives the notice of it. In such a case, the designated official must incorporate in the notice a brief statement of the reasons and findings for the amendment to be adopted. The airport operator may file a petition for reconsideration under paragraph (c) of this section; however, this does not stay the effective date of the emergency amendment.
