(1) Within existing funds, the state auditor must establish a toll-free telephone line that is available to public employees and members of the public to recommend measures to improve efficiency in state and local government and to report waste, inefficiency, or abuse, as well as examples of efficiency or outstanding achievement, by state and local agencies, public employees, or persons under contract with state and local agencies.

(2) The state auditor must prepare information that explains the purpose of the hotline, and the hotline telephone number must be prominently displayed in the information.

The state auditor must publicize the availability of the toll-free hotline through print and electronic media and other means of communication with the public.

All documents related to the report and subsequent investigation are also confidential until completion of the investigation or audit or when the documents are otherwise statutorily exempt from public disclosure.

(5) The state auditor must prepare a written determination of the results of the investigation performed, including any background information that the auditor deems necessary. The state auditor must report publicly the conclusions of each investigation and recommend ways to correct any deficiency and to improve efficiency. The reports must be distributed to the affected state agencies.
