Public Utility Stability Act.

HB 4508, the Public Utility Stability Act, allows publicly owned water and sewer utilities (like city or county systems) to automatically increase rates annually without needing commission approval or local government ordinances. The bill sets rate increases equal to the annual change in the U.S. Bureau of Labor Statistics' Water and Sewerage Maintenance Index, calculated between specific September dates. Utilities must file revised tariffs and provide notice, but increases matching the index are considered fair and reasonable. Smaller utilities (under 4,500 customers or $3 million revenue) face limited commission review if increases exceed the index, while larger systems may be reviewed by county commissions. The bill aims to simplify rate adjustments tied to inflation for essential water and sewer services.
