s <br /> The pre-treatment process is performed to reduce the metal <br /> content and to adjust the pH to remove cyanide before <br /> discharging into the sewer system. DPI has a wastewater <br /> discharge permit from the City of Stockton. <br /> DPI generates filter cake from its solidification of <br /> sludge during the de-watering filter press process. DPI <br /> manifested 24.7 tons of filter press cake in 1990, and <br /> 28.0 tons in 1991. The filter cake was hauled as <br /> hazardous waste by Haz Control, 731 Renx Lane, Gilroy, CA, <br /> 95020, to Cypress Miami Mines in Inspiration, Az. <br /> During the October 10, 1991 inspection, a third hazardous <br /> wastestream was identified. DPI generates floor sweepings <br /> from metal sanding and burnishing of chrome bumpers. <br /> VII. VIOLATIONS: <br /> 1. DPI was storing hazardous waste in containers without <br /> proper lids. <br /> 2. DPI did not have a personnel training program that <br /> ensured the facility's compliance with Title 22 and <br /> employee training was not properly documented in <br /> employee files. <br /> 3. DPI disposed of floor sweepings from metal sanding <br /> and burnishing operations as solid waste without <br /> first analyzing the sweepings for hazardous <br /> constituents. <br /> 4. DPI's emergency equipment was inadequate to handle an <br /> emergency. <br /> 5. DPI's emergency equipment was not located in the area <br /> where it will be required. <br /> 6. DPI had no alarm in the plating room to signal an <br /> emergency. <br /> 7. DPI's emergency equipment was not clean and ready for <br /> use. <br /> VIII. OBSERVATIONS: <br /> Ms. Violett and I arrived at DPI at approximately 10:30 <br /> a.m. Upon arriving, we met Doug Baker, Vice President <br /> and General Manager. We identified ourselves and <br /> explained the nature of our inspection. <br /> 3 <br />
