Extended Temporary Duty (ETDY) Reduced Per Diem rate
NASA’s standard reduced per diem rate for ETDY travel is 65 percent under the current policy as defined in the NASA Procedural Requirements (NPR) 9750.1-3.1.2.
a. Consistent with 41 CFR 301-11.200, an ETDY authorization can include reasonable further reductions from this standard rate or limitations on approved lodging for unique circumstances, to the extent it can be determined in advance that such will substantially lower costs without mission impact. For example, if lodging is obtained at 50 percent per diem, the ETDY authorization should be adjusted to authorize a lower rate.
b. The reduced rate of reimbursement begins on the first day of travel regardless of the mode of transportation, except as noted in 3.1.3. Allowances are covered by the reduced per diem rate; therefore, NASA will authorize the employee a per diem rate (up to 65 percent) to reasonably cover expenses for a one bedroom furnished apartment. For ETDY greater than 90 days, first consideration should be given to long-term lodging facilities. Long-term lodging facilities are available on the GSA schedule at http://www.gsa.gov. If a long-term facility is not selected, proper justification should be provided.
