Section 335-7-6-.12 - Chemicals Used In Water Treatment

(1) Chemicals used in water treatment must be approved by the Department prior to use. Water Systems shall determine that the chemical or substance to be added and the proposed application rate meets the ANSI/NSF standard 60 or 61. Only products meeting these standards shall be used by supplier of water and certification that such a product meets these standards must be determined through evaluation by a program certified by the American National Standards Institute. Water Systems shall provide a list of the type, name, and manufacturer, and certification document requesting departmental approval prior to use of the substance or chemical. Water treatment chemicals containing acrylamide or epichlorohydrin are prohibited from use in water treatment plants unless the system provides annually a written certification to the department that when acrylamide and/or epichlorohydrin are used to treat water, the combination of dose and monomer level does not exceed the following levels: acrylamide - 0.05% dosed at 1ppm or equivalent. Epichlorohydrin - 0.01% dosed at 20 ppm or equivalent.

(2) Chemicals shall be stored in packages or containers as received or otherwise their containers shall be labeled to indicate the name of the chemical. Acid storage tanks must be vented to the outside atmosphere in a separate vent stack.

(3) Chemicals shall be controlled to prevent contamination with other chemicals and to eliminate any dangerous mixing of chemicals.
