Dilution

Section 406 Section 406.104  Dilution a)         Dilution of an effluent from a treatment works or from any wastewater source is not acceptable as a wastewater treatment method to meet the effluent standards in this Subpart D.  Rather, any person discharging contaminants to the waters of the State must provide the best degree of wastewater treatment consistent with technological feasibility, economic reasonableness, and sound engineering judgment. b)         When determining the best degree of treatment under this Section, the following will be considered: 1)         The degree of waste reduction that can be achieved by process change, improved housekeeping, and recovery of individual waste components for reuse; and 2)         Whether individual process wastewater streams should be segregated or combined. c)         Concentrations measured for determining compliance with Section 406.106 must be recomputed to exclude the effect of any dilution that is improper under this Section.
