TSS benchmark values are 100 mg/l except in ORW, HWQ, trout, and PNA waters where they are 50 mg/l.
SThe discharge shall not cause an instantaneous measurement of the turbidity of the receiving water to exceed: 10 NTU for freshwater streams, lakes, and reservois designated
as trout waters; 25 NTU for all lakes and reservois, and all salt water; 50 NTU for all other streams and surface waters. Turbidity may be monitored at the SDO.
