User-specific local limits for appropriate pollutants of concern shall be included in waste water pretreatment permits. 0.005 mg/l antimony 0.005 mg/l arsenic 1.000 mg/l barium 0.005 mg/l beryllium 0.003 mg/l cadmium 0.050 mg/l chromium 0.038 mg/l copper 0.010 mg/l cyanide 1.000 mg/l iron 0.00875 mg/l lead 0.0001 mg/l mercury 0.005 mg/l molybdenum 0.005 mg/l nickel 0.005 mg/l selenium 0.010 mg/l silver 0.175 mg/l zinc 1.0 mg/l nitrate nitrogen 10 mg/l sulfide 55 mg/l sulfate 65 mg/l chloride 1.000 mg/l fluoride 1.000 ug/l phenolic compounds 300 mg/lBOD 250 mg/l TSS 20 mg/l NH3-N 5 mg/l PO4-P (b) Industrial user-specific local limits for appropriate pollutants of concern shall be included in waste water permits and are considered pretreatment standards.
