Allows the board of trustees of "The Firemens' Retirement System of St. Louis City" to act as trustees and administer other pension plans

HB 1980 allows the existing board of trustees for St. Louis City's Firemen's Retirement System to also manage other pension plans for firefighters employed by cities outside of counties. The bill authorizes the same nine-person board to handle administration, rule-making, and investment duties for these additional plans while keeping financial records and expenses separate from the original retirement system funds. This change enables the board to oversee multiple pension programs without creating new governing bodies, provided that no benefits from the other plans are paid using the original system's money.
