Section 630.1113 - Using donated annual leave(a) Any donated annual leave an emergency leave recipient receives from an emergency leave transfer program may be used only for purposes related to the disaster or emergency for which the emergency leave recipient was approved. Each agency is responsible for ensuring that annual leave donated under the emergency leave transfer program is used appropriately.(b) Annual leave transferred under this subpart may be-(1) Substituted retroactively for any period of leave without pay used because of the adverse effects of the disaster or emergency; or(2) Used to liquidate an indebtedness incurred by the emergency leave recipient for advanced annual or sick leave used because of the adverse effects of the disaster or emergency. The agency may advance annual or sick leave, as appropriate (even if the employee has available annual and sick leave), so that the emergency leave recipient is not forced to use his or her accrued leave before donated annual leave becomes available.
