Sec.  1.1929   Deduction from employee's pay.

   (a) Deduction by salary offset, from an employee's current disposable pay,
   shall be subject to the following conditions:

   (1) Ordinarily, debts to the United States will be collected in full, in one
   lump sum. This will be done when funds are available for payment in one lump
   sum. However, if the employee is financially unable to pay in one lump sum
   or the amount of the debt exceeds 15 percent of disposable pay for an
   officially established pay interval, collection must be made in
   installments.

   (2) The size of the installment deductions will bear a reasonable
   relationship to the size of the debt and the employee's ability to pay (see
   the FCCS). However, the installments will not exceed 15 percent of the
   disposable pay from which the deduction is made, unless the employee has
   agreed in writing to the deduction of a greater amount.

   (3) Deduction will generally commence with the next full pay interval
   (ordinarily the next biweekly pay period) following the date: of the
   employee's written consent to salary offset, the waiver of hearing, or the
   decision issued by the hearing officer.

   (4) Installment deductions will be pro-rated for a period not greater than
   the anticipated period of employment except as provided in  Sec. 1.1930.
