The normal retirement date for any person who is a member of the Kansas public employees retirement system pursuant to subsection (b) of Kan. Stat. Ann. §§ 74-4999 and amendments thereto and who retires on or after July 1, 1994, shall be the first day of the month coinciding with or following the attainment of age 65 or age 62 with the completion of 10 years of credited service or the first day of the month coinciding with or following the date that the total of the number of years of credited service and the number of years of attained age of the person is equal to or more than 85. Any such person may retire before such member’s normal retirement date on the first day of any month coinciding with or following the attainment of age 55 with the completion of 10 years of credited service, upon the filing with the office of the retirement system of an application for retirement in such form and manner as the board may prescribe. Any member who retires before such member’s normal retirement date as provided in this subsection shall have such member’s retirement benefit determined as provided in subsection (2) of Kan. Stat. Ann. §§ 74-4915 and amendments thereto. Notwithstanding any provision of Kan. Stat. Ann. §§ 74-4915 and amendments thereto to the contrary, any person who is a member of the Kansas public employees retirement system pursuant to subsection (b) of Kan. Stat. Ann. §§ 74-4999 and amendments thereto and who retires on or after July 1, 1975, shall be entitled to the greater total retirement benefit of the following:

Stat. Ann. §§ 74-4902 and amendments thereto, and there shall be no reduction in such payments for any benefits which such member is receiving or is eligible to receive under the federal social security act.
