PRETREATMENT. The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to, or in lieu of, introducing such pollutants into the POTW for final treatment. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.
PRETREATMENT STANDARDS. Standards requiring pretreatment established by the state and/or federal government, including categorical pretreatment standards.
PROHIBITED DISCHARGE STANDARDS or PROHIBITED DISCHARGES. Prohibitions imposed by the town, the State of Indiana or the U.S. government against the discharge of certain substances. (These town prohibitions appear in § 53.61 of this Code.)
