Under the program, separation pay may be offered by a defense agency only—
(1)
with the prior consent, or on the authority, of the Secretary; and
(2)
to employees within such occupational groups or geographic locations, or subject to such other similar objective and nonpersonal limitations or conditions, as the Secretary may require.
A determination of which employees are within the scope of an offer of separation pay shall be made only on the basis of consistent and well-documented application of the relevant criteria.
