If, and only if, no suitable alternative provider is available, the chief officer of a department facility may authorize nonresidential services and supports of the developmental center to persons with developmental disabilities. A person with a developmental disability, a parent or legal guardian of a child with a developmental disability, or the conservator of a person with a developmental disability may request nonresidential services and supports. The chief officer may, in the best interests of the person, discontinue the nonresidential services and supports of a person at any time.
