D.C. Mun. Regs. tit. 6, r. 6-B1255
Upon approval of an application to become a leave recipient, annual leave bank hours shall be credited to the leave recipient effective the first pay period during which the employee suffered a substantial loss of income.
Annual leave bank hours shall not be used to liquidate any indebtedness for any period of advanced leave.
Annual leave bank hours shall not be credited to a leave recipient in amounts greater than necessary to provide the employee, when combined with any accrued leave, his or her biweekly basic pay.
The value of the annual leave received by a leave recipient from the annual leave bank shall be in an amount equal to the recipient's hourly rate of basic pay multiplied by the number of hours of annual leave received.
When a withdrawal is approved, the personnel authority shall reduce its annual leave bank by the dollar value corresponding to the annual leave credited to the leave recipient.
When there are insufficient funds in the annual leave bank to fulfill an applicant's request, the personnel authority may only approve an amount that does not cause the annual leave bank to exceed its available balance.
When leave recipients cannot be granted the full amount of annual leave requested because of insufficient leave bank balances, and additional hours are donated at a later date, the personnel authority shall first reevaluate the request(s) of the leave recipient(s) who did not receive the full amount of annual leave requested prior to acting on subsequently received applications.
Annual leave shall not be borrowed, contributed or otherwise transferred between the annual leave banks of the various District government personnel authorities nor between District government, Federal Government or any other leave banks.
