Security Threat Assessment adjudicators conduct threat assessments for every transportation worker seeking to obtain an endorsement, credential and/or privilege in a number of programs such as Aviation Worker, Indirect Air Carrier/Air Cargo, Registered Traveler and Transportation Worker Identification Credential. TSA expects that TTAC will add a significant number of new populations. Sol. No. HSTS02-08-I-TTC7108. Respond by July 23. Contact: Matthew Erbe, contract specialist, 571-227-1891, [email protected].
