Except as provided in §§ 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT): (a) For plants with a dairy products input of more than 85,000 lb/day of milk equivalent (more than 8,830 lb/day of BOD 5 input). Effluent characteristic Effluent limitations Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed— Metric units (kilograms per 1,000 kg of BOD 5 input) BOD 5 4.60 1.840 TSS 6.90 2.760 pH ( 1 ) ( 1 ) English units (pounds per 100 lb of BOD 5 input) BOD 5 0.460 0.184 TSS .690 0.276 pH ( 1 ) ( 1 ) 1 Within the range 6.0 to 9.0. (b) For plants with a dairy products input of 85,000 lb/day or less of milk equivalent (less than 8,830 lb/day of BOD 5 input). Effluent characteristic Effluent limitations Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed— Metric units (kilograms per 1,000 kg of BOD 5 input) BOD 5 6.126 3.063 TSS 9.188 4.594 pH ( 1 ) ( 1 ) English units (pounds per 100 lb of BOD 5 input) BOD 5 0.613 0.306 TSS .919 .459 pH ( 1 ) ( 1 ) 1 Within the range 6.0 to 9.0.
