Victor Road in <br /> Lodi, California. Certain wastes are produced during the manufacturing process. <br /> It is alleged that some, if not all, waste streams generated are potentially <br /> hazardous. These include wash water from the cleaning and iron phosphatizing <br /> pretreatment process portion of the galvanized steel painting operation, and <br /> liquid and soils paint residues. Minor incidental wastes may also be generated <br /> from the use of solvents for degreasing and general mechanical equipment <br /> cleaning procedures. <br /> Chemicals used at the facility generally include: alkaline cleaners comprised <br /> yc L ? <br /> of caustic soda and aliphatic and aromatic hydrocarbons; su"+W-ie acids used for <br /> pH adjustments; a phosphatizing solution and phosphate coating sealant con- <br /> taining phosphoric acid; boiler treatment compound containing caustic potash <br />
