We began the inspection in the urethane bumper repair and painting shop. No <br /> violations were noted in this area. <br /> Next we proceeded to the metal bumper core yard and repair shop. Bumpers are <br /> sanded, gro ind and repaired in this area. Floor sweepings are collected and stored <br /> in metal drums for later disposal as hazardous waste. The compressor oil waste <br /> noted in the 1992 inspection report has been eliminated in this location. A <br /> synthetic oil is now being used and changing occurs less frequently negating the <br /> need for loc lized collection. <br /> The inspection continued through the plating and polishing areas where no <br /> violations were noted. Stockton Plating is working to reduce hazardous waste <br /> production in these areas by adding floating discs (referred to as "UFO's") to <br /> reduce chromium evaporation and by sealing the copper plating room floor to <br /> reduce absorption. Mr. Parks also explained that they have managed to reduce <br /> the amount of hazardous waste generated by better product management and <br /> employee tr ining. The plating tanks are monitored more often to better control <br /> inventory and rinse tanks are back poured instead of emptied to conserve valuable <br /> metal product. The employees have also been trained to handle pieces more <br /> carefully to reduce drag out. <br /> Many of the quickly deteriorating wooden floor planks have been replaced in this <br /> area with more durable metal grating which needs less maintenance and lasts <br /> longer. <br /> From here vie inspected the job shop, treatment area, maintenance shop, <br /> hazardous materials storage area, and the hazardous waste storage area. In the <br /> aluminum anodizing and job production shop, I noticed that the cement floor <br /> beneath the strip area is badly deteriorated. I pointed this out to Mr. Parks who <br /> was very concerned. I explained that some of the corrosive products used can be <br /> very deleterious to concrete. <br /> The treatment system filters out the metal waste and disposes of the treated water <br /> to the municipal sewer system under permit. The permit was issued October 31, <br /> 1991, and li its disposal to 860,000 gallons per month. Mr. Parks stated that <br /> earlier this year, the City of Stockton Municipal Utilities Department (MUD) <br /> cited Stockton Plating, Inc. for discharge violations. After the inspection, I spoke <br /> with Richard Stiffler of MUD, and he explained that in January and February of <br /> 1994, severa copper waste discharge violations were noted and Stockton Plating <br /> was fined an put on probation. A correction order was issued and Stockton <br /> Plating made the necessary changes. Since those corrections, no violations have <br /> been noted. <br /> Stockton Plating has also made application to Cal-EPA, Department of Toxic <br /> Substance Control, for Permit by Rule for their treatment system. <br /> 5 <br />
