(a) If an owner/operator seeks to petition for reconsideration of a determination, required modification, denial of a request for amendment by the owner/operator, denial to rescind a TSA-required amendment, or denial of an alternative measure, the owner/operator must submit a written petition for reconsideration that includes a statement and any supporting documentation explaining why the owner/operator believes TSA's decision is incorrect.

(b) Upon review of the petition for reconsideration, the Administrator or designee will dispose of the petition by affirming, modifying, or rescinding its previous decision. This is considered a final agency action.
