Code of Federal Regulations Title 5. Administrative Personnel § 5.550.405 Determination of special allowances

(a) An agency must determine the travel expenses and per diem for an evacuated employee and the travel expenses for his or her dependents in accordance with the Federal Travel Regulation (FTR) and any applicable implementing agency regulations, whether or not the employee or dependents are actually covered by or subject to the FTR. In addition, an agency may authorize per diem for dependents of an evacuated employee at a rate equal to the rate payable to the employee, as determined in accordance with the FTR (except that the rate for dependents under 12 years of age is one-half this rate), whether or not the employee or dependents are actually covered by or subject to the FTR. Per diem for an employee and his or her dependents is payable from the date of departure from the evacuated area through the date of arrival at the safe haven, including any period of delay en route that is beyond an evacuee's control or that may result from evacuation travel arrangements.

(b) Subsistence expenses for an evacuated employee or his or her dependents shall be determined at applicable per diem rates for the safe haven or for a station other than the safe haven that has been approved by appropriate authority. Such subsistence expenses shall begin to be paid on the date following arrival and may continue until terminated. The subsistence expenses shall be computed on a daily rate basis, as follows:

(c) Payment of subsistence expenses shall be decreased by the applicable per-person amount for any period during which the employee is authorized regular travel per diem in accordance with the FTR.
