New summer and winter limits for BOD5 and NH3N were derived. They are as follows: Summer Winter BOD5 18 mg/1 24 mg/1 or 30 mg/1 NH3N 5 mg/1 13 mg/1 or 11 mg/1 DO 5.0 mg/1 5.0 mg/1 If the treatment plant could meet a dissolved oxygen concentration in the effluent of 6.0 mg/1, the limits would be slightly better. They are: CH:cs Summer Winter BOD5 16 mg/1 or 20 mg/1 24 mg/1 or 30 mg/1 NH3N 6 mg/1 or 5 mg/1 14 mg/1 or 12 mg/1 DO 6 mg/1 6 mg/1 If we can be of any additional assistance, please notify us.
