The program fee fund is hereby created in the state treasury. All fees collected pursuant to sections 5123.161, 5123.164, and 5123.19 of the Revised Code shall be credited to the fund. Money credited to the fund shall be used solely for the department of developmental disabilities’ duties under sections 5123.16 to 5123.1611 and 5123.19 of the Revised Code and to provide continuing education and professional training to providers of services to individuals with developmental disabilities. If the money credited to the fund is inadequate to pay all of the department’s costs in performing those duties and providing the continuing education and professional training, the department may use other available funds appropriated to the department to pay the remaining costs of performing those duties and providing the continuing education and professional training.
