41 CFR 301-50.2: -50.2 Exceptions to mandatory use of ETS, TMS, or TMC.

(a) The agency head or their designee may grant an individual case exception in writing or through electronic means to the required use of ETS, or the agency's TMC or TMS if otherwise exempted from ETS use per paragraph (b) of this section. Any exception granted must be consistent with any contractual terms applicable to the TMC, TMS, or ETS.

(b) The Administrator of General Services or the Administrator's designee may grant an agency-wide exception (or exempt a component thereof) from the required use of ETS when requested by the head of a Department (cabinet-level agency) or head of an independent agency when the agency has presented a business case analysis to the General Services Administration that proves that it has an alternative TMS to the ETS and is in the best interest of the Government.

(1) As a condition of receiving an exception, the agency must agree to conduct annual business case reviews of its TMS and must provide to the ETS Program Management Office (PMO) data elements required by the ETS PMO in a format prescribed by the ETS PMO.

(2) Requests for exceptions should be addressed to the Administrator of General Services and sent to travelpolicy@gsa.gov with full justification and/or analysis.
