(a) Any exempt municipality which lies wholly within a county which has established or joined in establishing a county department of health may, by an ordinance enacted at any time, decide to become subject to the jurisdiction of the county department of health at the time of its establishment or at any time thereafter. Upon the enactment of such ordinance, the municipality shall dissolve its department or board of health and cease to exercise the powers vested by law in such department or board, except that the dissolution of the department or board of health of the municipality shall not remove from the municipality the power granted to it by law to erect, purchase, or lease, and administer hospitals, either separately or jointly with another political subdivision.

(b) Any exempt municipality which lies partly within a county which has established or joined in establishing a county department of health and partly within a county which has not established or joined in establishing a county department of health may, by an ordinance enacted at any time, provide that the part of the municipality which lies within the county which has established or joined in establishing a county department of health shall become subject to the jurisdiction of such department. The department or board of health of the municipality shall continue to exercise the powers and duties vested in it in that part of the municipality which lies in the county which has not established or joined in establishing a county department of health. The enactment of the ordinance placing part of the municipality within the jurisdiction of a county department of health shall not remove from the municipality the power granted to it by law to erect, purchase, or lease, and administer hospitals in any part of the municipality, either separately or jointly with another political subdivision.

(c) Whenever all the counties in which an exempt municipality lies have established or joined in establishing county departments of health, the municipality may, by an ordinance enacted at any time, decide to become subject to the jurisdiction of each respective county department of health. Upon the enactment of such ordinance, the municipality shall dissolve its department or board of health and cease to exercise the powers vested by law in such department or board, except that the dissolution of the department or board of health of the municipality shall not remove from the municipality the power granted to it by law to erect, purchase, or lease, and administer hospitals, either separately or jointly with another political subdivision.

(d) In the event that an exempt municipality does not decide to become subject to the jurisdiction of a county department of health, or in the event that an exempt municipality retains its department or board of health in accordance with subsection (b) of this section, or in the event that the county or counties in which a municipality having a department or board of health is located have not established or joined in establishing a county department of health, the municipality may receive State grants as provided in section 25 of this act.¹

(e) Any municipality located in a county of the first class having a department or board of health may receive State grants as provided in section 25 of this act.
