Any county commission, or political subdivision, or county 911 public safety answering point employing emergency medical services officers or 911 personnel may by a three-fifths vote of its governing body, or by a majority vote of its electors, elect to become a participating public employer and thereby include its emergency medical services officers and 911 personnel in the membership of the plan. The clerk or secretary of each such county commission, or political subdivision, or county 911 public safety answering point governing board electing to become a participating public employer shall certify the determination of the county commission, or political subdivision, or county 911 public safety answering point governing board to the Consolidated Public Retirement Board within 10 days from and after the vote of the governing body or the canvass of votes upon such action.
