If a township is not included in a mental health district organized under the Community Mental Health Act, the township board may provide mental health services (including services for the alcoholic and the drug addicted, and for persons with intellectual disabilities) for residents of the township by disbursing funds, pursuant to an appropriation, to mental health agencies approved by the Department of Human Services, alcoholism treatment programs licensed by the Department of Public Health, drug abuse facilities approved by the Department of Human Services, and other services for substance use disorders approved by the Department of Human Services. To be eligible for township funds disbursed under this Section, an agency, program, facility, or other service provider must have been in existence for more than one year and serve the township area.
