The moneys in such fund shall not be commingled with any funds of the county. Moneys in the fund shall be used solely by the county for funding public safety services, including, but not limited to, fire protection activities and ambulance services, and for funding the promotion of tourism within the county. Seventy-five percent of the surcharges collected shall be used, upon appropriation, solely for funding public safety services, and twenty-five percent of the surcharges collected shall be used, upon appropriation, for tourism marketing and promotional purposes.
