S. 3959Senate118th Congress (2023-2025)Enacted

Transportation Security Screening Modernization Act of 2024

Introduced March 14, 2024

AI-Generated Summary

Updated January 20, 2026 at 3:17 PM UTC

The Transportation Security Screening Modernization Act of 2024 directs the Transportation Security Administration (TSA) to simplify and combine the application and renewal process for multiple security threat assessment programs, such as the Transportation Worker Identification Credential (TWIC) and the Hazardous Materials Endorsement. It aims to let individuals enroll once, pay a lower combined fee, and have synchronized expiration dates, while also requiring audits to cut duplicate costs and improve access, especially for rural applicants.

Key Provisions

  • Within two years, TSA must allow a single enrollment at any authorized center to be used for multiple threat‑assessment programs, sharing biometric and biographic data across programs
  • Offer combined enrollment at a fee lower than the total of separate fees and provide a faster renewal process
  • Align expiration dates of assessments across programs and provide states with these dates to prevent mismatched commercial driver’s license authorizations
  • Permit enrollment in additional programs at the minimum cost needed for printing, issuance, case‑management, and any extra data collection
  • Require TSA to post streamlining information on a public website and brief Congress on progress within 180 days of enactment
  • Mandate a Comptroller General audit within one year to identify redundancies, cost duplications, and access issues, especially for rural applicants
  • Require TSA to implement audit recommendations within one year of the report and to report implementation timelines and justifications to the relevant congressional committees

Streamlining

(1)

In general

Not later than 2 years after the date of the enactment of this Act, the Administrator shall take such actions as are necessary, including issuance of an interim final rule if needed, to streamline the procedures for individuals applying for or renewing enrollment in more than one TSA security threat assessment program, in particular, the TWIC and HAZMAT Endorsement programs, and any other credentialing programs as determined by the Administrator, by—

(A)

permitting an individual to enroll at any TSA authorized enrollment center once for a threat assessment program endorsement and use the application, including associated biometric and biographic data, as well as information generated by TSA’s vetting, for one of such programs to enroll in any other of such programs;

(B)

permitting an individual to visit any TSA authorized enrollment center and enroll in more than one TSA security threat assessment program at the same time for a fee that is less than the cumulative fee that would otherwise be incurred for each such program separately;

(C)

permitting an individual to undergo a streamlined and expeditious renewal process;

(D)

aligning the expiration of an individual’s successful, valid eligibility determination with the expiration of that individual’s eligibility to participate in subsequent TSA security threat assessment programs to which the individual applies;

(E)

providing to States the expiration dates for each individual’s TSA security threat assessment to ensure a commercial driver’s license of an individual who holds a HAZMAT Endorsement does not indicate the individual is authorized to transport hazardous materials after the expiration date of the enrollment of the individual in the HAZMAT Endorsement security threat assessment program if such commercial driver’s license has an expiration date that is different from the expiration date of such enrollment; and

(F)

enrolling an individual in a subsequent TSA security threat assessment program at the minimum cost necessary for the TSA to cover printing, issuance, and case management costs, costs associated with the collection of any additional biometric and biographic data in accordance with paragraph (3), and other costs that are not duplicative.

(2)

State requirements for streamlining

Not later than 6 months after the date of the enactment of this Act, the States shall carry out the responsibilities of the States pursuant to section 5103a of title 49, United States Code.

(3)

Special rule

If an individual under this subsection is at different times applying for or renewing enrollment in more than one TSA security threat assessment program, such individual may be required to revisit a TSA authorized enrollment center for the collection of additional data, such as biometrics, necessary for any such program that were not so collected in connection with any other such program.

(b)

Publication

The Administrator shall post on a publicly available website of the TSA information relating to the streamlining of the enrollment processes for individuals applying for more than one TSA security threat assessment program described in subsection (a).

(c)

Expedited rulemaking

Notwithstanding sections 551 through 559 of title 5, United States Code, nothing in this section shall require notice and comment rulemaking, and to the extent it is necessary to add additional requirements for which limited rulemaking may be advisable, the Administrator shall implement such requirements through publication of an interim final rule.
