Waiver of Overpayment of Pay and Per Diem

A former federal employee requested reconsideration of denial of waiver of overpayments for per diem and salary. Per diem is a travel allowance which is expressly excluded from waiver by statute. Request for waiver of salary overpayment was filed over 3 years after discovery of error, and waiver was thus barred by 3 year statutory limitation.
