Some members who become disabled may be eligible for a disability
  retirement. The two types of disability retirement are service
  connected disability and non-service connected disability.
  Service Connected Disability Retirement
  If the Retirement Board determines that you are permanently
  physically or mentally unable to continue active performance of
  your job duties because of accident, injury or illness arising
  out of and in the course of your employment, you may be eligible
  for a service connected disability retirement. There is no
  minimum age or service credit requirement for a service connected
  disability retirement.
  
  The service connected disability retirement benefit will be equal
  to 50% of your final compensation or the amount of a regular
  service retirement benefit, whichever is greater.
  Non-Service Connected Disability Retirement
  If you have five years of eligible service and the Retirement
  Board determines that you are permanently physically or mentally
  unable to continue active performance of your job duties because
  of accident, injury or illness that did not arise out of and in
  the course of your employment, you may be eligible for a
  non-service connected disability retirement.
  
  The non-service connected disability retirement benefit is based
  on the formula of 90% of 1/6 of final compensation
  multiplied by the number of years of service, with the maximum
  benefit being 1/3 of final compensation, or your regular service
  retirement benefit, whichever is higher.
