41 CFR 302-18.4: -18.4 Duration of test programs and requesting an extension.

(a) The duration of a test program is up to four years from the date of authorization unless terminated prior to that time by the Administrator. The agency conducting a test program may also terminate the test program at any time by providing written notice of the termination to the Administrator.

(b) The Administrator may grant test program extensions of up to an additional four years. To request an extension, the head of the agency or designee must submit a request to extend the test program to the Administrator of General Services via the Office of Government-wide Policy at travelpolicy@gsa.gov, not later than 120 days prior to the expiration of the test period. The request for extension must contain the test program results to that date and clearly enumerate the benefits, qualitatively or quantitatively or both, of granting a test program extension and must specify the duration of time for which an extension is requested.
