Section 74:51:01:26 - Zone of mixing for wastewater discharges to flowing waters

A zone of mixing is allowed for the discharge of wastewater to a flowing water. Each properly treated wastewater discharge to a flowing water must meet the chronic criterion established for the designated beneficial uses of the receiving water at the edge of its zone of mixing. Concentrations of substances in the discharge must not cause the acute criterion established for the designated beneficial uses of the receiving water to be exceeded. The water quality criteria set forth in §§ 74:51:01:06, 74:51:01:08, 74:51:01:09, and 74:51:01:10 apply within the zone of mixing.
