If you fail to respond to the notice of violation within 30 days of receipt, TSA will issue you a final notice. If you fail to respond to the final notice within 15 days of receipt, TSA will then assess against you the full civil penalty amount proposed in your NOV, and may refer this matter to the U.S. Department of the Treasury or to the U.S. Department of Justice for collection of this debt owed to the U.S. government.
