§ 52.049 CROSS CONNECTION CONTROL REGULATIONS.
   (A)   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 supply of the town 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 and tagged as per requirements of the town Building Department and IDEM, Drinking Water Division in accordance with Rule 320 IAC 3-9.
   (B)   It shall be the duty of the town Building Department to cause inspections to be made of all properties served by the public water system where cross connection with the public water system is deemed possible and/or a hazard. The Building Department shall develop and supply the Town Council with a listing of utility customers classified as cross connection hazards by 320 IAC 3-9.1-4© and shall submit a schedule of annual inspections and/or reinspection of these customers and any others deemed a hazard.
   (C)   Upon presentation of credentials, the representative of the town shall have the right to request entry at any reasonable time to examine any property served by a connection to the public water system of the town for cross connections. On request, the owner, lessee, or occupant of any property so served shall furnish to the inspection agency any pertinent information regarding the pipe system or systems on such property. The refusal of access or refusal of requested pertinent information shall be deemed evidence of the presence of cross connections.
   (D)   The town Water Utility is hereby authorized and directed to discontinue water service to any property wherein any connection in violation of this chapter exists, and to take such other precautionary measures deemed necessary to eliminate any danger of contamination of the public water system. Water service shall be discontinued only after ten days notice is served on the owner, lessee, or occupants of the property or premises where a violation is found or suspected to exist. Water service to such property shall not be restored until the cross connection(s) has been eliminated in compliance with the provisions of this chapter.
   (E)   Service may be immediately discontinued if it is deemed by the administrative authority that a cross connection or an emergency endangers public health, safety, or welfare and requires immediate action, and a written finding to that effect is filed with the Clerk-Treasurer of the town and delivered to the consumer's premises. The consumer shall have an opportunity for hearing within ten days of such emergency discontinuance.
   (F)   All consumers-using toxic or hazardous liquids, all hospitals, mortuaries, wastewater treatment plants, laboratories, and all other hazardous users shall install and maintain at their expense a reduced-pressure-principle backflow preventer in the main water service line serving each building on the premises. The backflow preventer shall be located in an easily accessible location not subject to flooding or freezing and must be installed and inspected in accordance with 320 IAC 3-9.1 and the Indiana Plumbing Code. Proof of inspection shall be given to the Water Utility.
   (G)   This chapter does not supersede the locally adopted Indiana Plumbing Rules but is supplementary to it.
   (H)   The town shall not be responsible for damage caused by thermal expansion resulting from the placement of any type of backflow or cross connection prevention device or any other type of chocking device. An auxiliary relief valve or expansion chamber shall be installed in such a way as to limit thermal expansion of the water being heated to not more than 80 PSI static pressure on the system.
