DOT Order 3910.1 Series Appendix A

Categorization of Employees for Testing

Testing Designated Positions (TDPs).

Safety/Security Critical - These are positions characterized as having critical safety or security responsibilities, related to the mission of the Department. The job functions associated with these positions have a direct and immediate impact on public health and safety, the protection of life and property, law enforcement, or national security. These positions require the highest degree of trust and confidence. Employees whose position require access to Confidential, Secret, Top Secret information are included as TDPs regardless of their organization or occupation.

Drug-only TDPs.

E.O. 12564 requires drug testing of safety- and security-sensitive positions in DOT.rug and alcohol TDPs. The Omnibus Act mandates drug and alcohol testing for FAA employees whose duties include responsibility for safety-sensitive functions and for any other DOT employee whose position requires a CDL. The Omnibus Act does not mandate drug and alcohol testing for other safety-sensitive employees outside FAA, or for any security-sensitive employees within DOT. Since the requirement for a CDL is not specific to a particular occupational series, this appendix does not identify every position in DOT which requires this licensure. The Operating Administrations must maintain the CDL employee listing and coordinate updates with the DDO.

Non-TDPs.

All positions that are not designated as TDPs are designated as non-TDPs

Position Coverage By Occupation.

The categorization of all other DOT positions is accomplished within the context of their Departmental element and their job duties within that organization. To assure overall consistency, category determinations for including or excluding positions as either a TDP or a non-TDP will be made by the Assistant Secretary for Administration in consultation with the Departmental organization. References to a given job, occupational series or family include all supervisors and employees in the occupation regardless of pay plan, unless otherwise noted.

Justification Statements For TDPs.

With the exception of positions requiring a CDL, each determination by the Departmental element to include a particular job occupation as a TDP shall be supported by a justification statement clearly describing why the job is safety/security critical and specifying the adverse consequences that would likely occur if an incumbent in that position were to use illegal drugs, or where appropriate, misuse alcohol. A current justification statement for each job or occupation included as a TDP shall remain on file with the Assistant Secretary for Administration, who reserves the right to review each justification statement to assure overall consistency with the DOT drug program and among varying occupations throughout the Department and make appropriate recommendations.
