(a) C.E.T.A. Employee. Any person hired by the City under the Comprehensive Employment and Training Program Act established by the Federal Government.[37]

(2) Any C.E.T.A. employees who continued in employment with the City after the termination of their C.E.T.A. employment or who later re-entered the service of the City pursuant to provisions of § 22-201 (Membership Upon Employment) are entitled, at their individual option, to purchase credited service under the Retirement System for the period of their service as C.E.T.A. employees. The employee shall be obligated to make contributions at the rate of 6% of the salary that the employee earned for the period of credited service purchased plus interest on that amount calculated from the date the employee was directly transferred from the C.E.T.A. program to permanent City employment, or, if later re-employed, the date the employee was separated from the C.E.T.A. program. Interest shall be charged at the current rate determined by the Board's actuary to compensate the Pension Fund for lost interest.

(3) Any payments which may be due from former C.E.T.A. employees under this section may be paid by installment under the provisions of § 22-806 (Installment Payments).
