Section 375-A. Non-contributory retirement plan for state employees

a.
  Notwithstanding any other provision of law to the contrary,  no  further
  contributions  to the retirement system, as provided in subdivision b of
  section three hundred twenty-one of this chapter, shall be  required  of
  any member in the employ of the state; provided, however, in the case of
  persons  in  the employ of the state who last became members on or after
  July first, nineteen hundred seventy-three, such required  contributions
  shall  be waived only until the payroll period immediately prior to that
  the first day of which  is  nearest  to  July  first,  nineteen  hundred
  seventy-four.
    b.  Contributions shall be made to the pension accumulation fund by or
  on account of the state, as provided in section three  hundred  sixteen,
  three  hundred seventeen and three hundred forty-two of this chapter, at
  a rate fixed by the actuary which shall be computed to be sufficient  to
  provide the benefits established by section three hundred seventy-five-c
  of this chapter on account of members in the employ of the state.
    c.  Nothing  contained  in  this  section  shall  impair the rights of
  persons, who became members before August nineteenth,  nineteen  hundred
  sixty-six,  to  make  contributions pursuant to subdivision i of section
  three hundred twenty-one of this chapter.
    d. Any member who has elected to  contribute  at  a  certain  rate  of
  contribution  in  accordance  with  the  provisions  of subdivision j of
  section three hundred twenty-one of  this  chapter,  shall  continue  to
  contribute  at  such  rate  until his election under said subdivision is
  withdrawn.
    e. Any member  in  service  on  August  nineteenth,  nineteen  hundred
  sixty-six,  may  by  written notice duly acknowledged and filed with the
  comptroller  on  or   before   August   eighteenth,   nineteen   hundred
  sixty-seven,  elect  to  contribute  to  the  retirement system. Where a
  member makes an election to contribute, as herein provided for, he shall
  contribute to the  retirement  system  as  otherwise  provided  in  this
  chapter.  One year or more after the filing of the notice of election to
  contribute, the member may withdraw  such  election  and  elect  not  to
  contribute.
