Pretreatment standards for existing sources (PSES).

Except as provided in 40 CFR 403.7 and 403.13, any existing source subject to this subpart that introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and must achieve the following pretreatment standards for existing sources (PSES): (a) Sintering operations with wet air pollution control system. The following table presents PSES for sintering operations with wet air pollution control systems: Subpart B—Pretreatment Standards for Existing Sources (PSES) Regulated parameter Maximum daily 1 Maximum monthly avg. 1 Ammonia-N 2 3 0.0150 0.00501 Cyanide 2 0.00300 0.00150 Phenols (4AAP) 2 0.000100 0.0000501 Lead 0.000451 0.000150 Zinc 0.000676 0.000225 2,3,7,8-TCDF <ML 1 Pounds per thousand lb of product. 2 The pretreatment standards for these parameters apply only when sintering wastewater is co-treated with ironmaking wastewater. 3 The pretreatment standards for ammonia are not applicable to sources that discharge to a POTW with nitrification capability (defined at § 420.02(s)). (b) Sintering operations with dry air pollution control system. There shall be no discharge of process wastewater pollutants to POTWs. [67 FR 64265, Oct. 17, 2002]
