Code of Federal Regulations Title 41. Public Contracts and Property Management § 41.301–73.102 May we grant a traveler an exception from required use of TMS or ETS once we have fully deployed ETS within the agency?

(1) Such use would result in an unreasonable burden on mission accomplishment (e.g., emergency travel is involved and TMS/ETS is not accessible;  the traveler is performing invitational travel;  or the traveler has special needs or requires disability accommodations in accordance with part 301–13 of this chapter).

(2) Such use would compromise a national security interest.

(3) Such use might endanger the traveler's life (e.g., the individual is traveling under the Federal witness protection program, or is a threatened law enforcement/investigative officer traveling under part 301–31 of this chapter).
