    Sec. 16-136.2. Minimum retirement annuity.
    (a) Any annuitant receiving a retirement annuity under this Article is entitled to such additional amount of retirement annuity under this Section, if necessary, that is sufficient to provide a minimum retirement annuity of $10 per month for each year of creditable service forming the basis of the retirement annuity, up to $300 per month for 30 or more years of creditable service. Effective January 1, 1984, the minimum retirement annuity under this Section is $15 per month per year of service up to $450 per month. Beginning January 1, 1996, the minimum retirement annuity payable under this Section shall be $25 per month for each year of creditable service, up to a maximum of $750 per month for 30 or more years of creditable service.
    An annuitant entitled to an increase in retirement annuity under this Section shall be entitled to such increase in retirement annuity effective the later of (1) September 1 following attainment of age 60; (2) September 1 following the first anniversary in retirement; or (3) the first of the month following receipt of the required qualifying contribution from the annuitant.
    (b) An annuitant who qualifies for an additional amount of retirement annuity under subsection (a) of this Section must make a one-time payment of 1% of the monthly average salary for each full year of the creditable service forming the basis of the retirement annuity or, if the retirement annuity was not computed using average salary, 1% of the original monthly retirement annuity for each full year of service forming the basis of the retirement annuity.
    (c) The minimum retirement annuity provided under this Section shall continue to be paid only to the extent that funds are available in the minimum retirement annuity reserve established under Section 16-186.3.
    (d) The annual increase provided on and after September 1, 1977 under Section 16-136.1 and on and after January 1, 1978 under Section 16-133.1 shall be paid in addition to the minimum retirement annuity. Where an initial increase is first payable on or after September 1, 1977, only that portion of the increase based on the period in retirement after August 31, 1976, under Section 16-136.1 and after December 31, 1976, under Section 16-133.1 may be added to the minimum retirement annuity.
