(B) No person, firm, or corporation shall establish or permit to be established or maintain or permit to be maintained any cross connection. No interconnection shall be established whereby potable water from a private, auxiliary, or emergency water supply other than the regular public water supply of Whiteland may enter the supply or distribution system of said municipality, unless such private, auxiliary, or emergency water supply and the method of connection and use of such supply shall have been approved by the Whiteland Water Department and by the Indiana Department of Environmental Management in accordance with 327 IAC 8-10.

The consumer shall have an opportunity for hearing within ten days of such emergency discontinuance.
(G) All consumers using toxic or hazardous liquids, all hospitals, mortuaries, wastewater treatment plants, laboratories, and all other hazardous users shall install and maintain a reduced pressure principal backflow preventer in the main water line serving each building on the premises.

(H) The reduced pressure principle backflow preventers shall not be installed below ground level.
(I) The provisions of this section do not supersede the Indiana Plumbing Code, IDEM Rule 327 IAC 8-10 or any other provision of this chapter, but is supplementary to them.
