Wastewater that undergoes pretreatment before discharge includes Chromate Passivation line rinse waters and concentrates, Zinc Phosphate line rinse waters and concentrates, Zinc Manganese line rinse waters and concentrates, Chemfilm (Alodine) line rinse waters and concentrates, and air scrubber pollution control wastewater. Industrial process waters discharge to Outfall 260 via a weir box. For compliance sampling, 24 hour flow proportional composite samples are pulled from the weir box via a composite sampler. Discharge totalizer numbers are documented daily. The boiler sump discharge line has a paddle wheel totalizer that is used to determine blowdown and reverse osmosis brine flow. This water flows to the sanitary line. RO softener backwash is metered and discharged to the sanitary line as well.

Process lines are 600 EN, 300 EN, Anodize/Chem film, Anodize Type II and Type III, and MSL-1 (miscellaneous line where Passivation or Phosphating can occur). Concentrates, dead rinses, and rinse overflows are generated from different processes (Phosphating, Anodizing, Acid Etching, and Electroless Nickel Plating) and are batch treated on-site and pH adjusted before final discharge through site SS1 or shipped off site for disposal. The Passivation line is the source of hexavalent chrome in the wastewater. The Passivation line consists of concentrates and overflowing rinses only. Air compressor blow down, boiler blow down, water softener backwash, and RO backwash are discharged directly to the sanitary sewer without treatment.
