(B) A person may use, sell, manufacture, or distribute for use or sale a cleaning agent that contains greater than zero percent phosphorus by weight but does not exceed eight and seven-tenths percent phosphorus by weight that is a substance excluded from the zero percent phosphorus limitation of this section by regulations adopted by the Department of Health and Environmental Control which are based on a finding that compliance with this section would:

(1) create a significant hardship on the user; or

(2) be unreasonable because of the lack of an adequate substitute cleaning agent.

(C) This section does not apply to a cleaning agent that is:

(1) used in dairy, beverage, or food processing equipment;

(6) used as a water softening chemical, antiscale chemical, or corrosion inhibitor intended for use in closed systems such as boilers, air conditioners, cooling towers, or hot water heating systems.

(D) The Department of Health and Environmental Control shall promulgate regulations to administer and enforce the provisions of this section. A cleaning agent held for sale or distribution in violation of this section may be seized by appropriate administrative or law enforcement personnel. The seized cleaning agents are considered forfeited.

(E) A person who knowingly sells, manufactures, or distributes any cleaning agent in violation of the provisions of this section shall receive a written warning from the Department of Health and Environmental Control for the first violation. For a subsequent violation, the person is guilty of a misdemeanor and, upon conviction, must be fined not more than five thousand dollars or imprisoned not more than one year. Each unlawful sale constitutes a separate violation.

(F) The provisions of this section may not restrict sale by a retailer of a household dishwashing detergent product from inventory existing and in stock at the retailer on July 1, 2012.
