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 processing more than 175,000 lb/day of milk equivalent (more than 18,180 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 1.375 0.550 TSS 2.063 .825 pH ( 1 ) ( 1 ) English units (pounds per 100 lb of BOD 5 input) BOD 5 0.138 0.055 TSS 0.206 .083 pH ( 1 ) ( 1 ) 1 Within the range 6.0 to 9.0. (b) For plants processing 175,000 lb/day or less of milk equivalent (less than 18,180 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 1.825 0.913 TSS 2.738 1.369 pH ( 1 ) ( 1 ) English units (pounds per 100 lb of BOD 5 input) BOD 5 0.183 0.091 TSS .274 .137 pH ( 1 ) ( 1 ) 1 Within the range 6.0 to 9.0.
