D.C. Mun. Regs. tit. 6, r. 6-B1252
An employee may make voluntary written application to the annual leave bank established by his or her personnel authority to become a leave donor at any time during the leave year subject to the limitations provided in § 1252.3. The application shall specify the number of hours of annual leave to be donated and any other information the personnel authority may deem necessary.
The value of the leave donated by a leave donor shall be an amount equal to the donor's hourly rate of basic pay multiplied by the number of hours of annual leave donated.
A leave donor may not donate more than a total of one-half (1/2) of the amount of annual leave that the leave donor would be entitled to accrue during the leave year in which the donation is made, except that a leave donor may donate restored annual leave without limitation.
The total amount of annual leave to be donated by a leave donor must be available in the leave account of the leave donor at the time he or she makes application to donate such annual leave; and shall be deducted from the leave donor's leave account effective on the first full pay period following approval of the application by the personnel authority.
Once donated, annual leave shall not be recredited to the leave donor.
A leave donor shall become a leave bank member of the leave bank established by his or her personnel authority for any leave year in which he or she donates at least four (4) hours of annual leave to that leave bank.
