5 CFR 630.704 - Granting shore leave.
(b) Accumulation. Shore leave is in addition to annual leave and may be accumulated for future use without limitation.
(d) Lump-sum payment. Shore leave may not be the basis for lump-sum payment on separation from the service.
(e) Terminal leave.
(1) Except as provided by paragraph (e)(2) of this section, an agency shall not grant shore leave to an employee as terminal leave. For the purpose of this paragraph terminal leave is approved absence immediately before an employee's separation when an agency knows the employee will not return to duty before the date of his separation.
(f) Forfeiture of shore leave. Shore leave not granted before (1) separation from the service, or (2) official assignment (other than by temporary detail) to a position in which the employee does not earn shore leave, is forfeited. When an official assignment will result in forfeiture of shore leave, the agency to the extent administratively practicable shall give an employee an opportunity to use the shore leave he has to his credit either before the reassignment or not later than 6 months after the date of his reassignment when the agency is unable to grant the shore leave before the reassignment.
