. ' <br /> Mr. Mannor escorted Ambacher, Oz and I on a tour of SWPC where he <br /> described the manufacturing process. The first stop was the pickling <br /> process which consists of a series of chemical dip tanks. At the' end <br /> of the pickling operation, 3-55 gallon drums were noted, which <br /> contained scale from the heat exchanger. These drums were open and <br /> unlabeled. <br /> After viewing the area where the steel rod was passed through reducing <br /> dies and twisted into a pre-stress strand, Mr. Mannor lead Ambacher, <br /> Oz and I outside where I observed zinc phosphate filter cake in large <br /> plastic bags sitting on the ground. One of the bags had ruptured and <br /> its contents had spilled onto the ground. <br /> At this time, Ambacher, Oz and I proceeded to a small shed and <br /> adjacent area where product oil and waste oil was stored. Mr. Mannor <br /> indicated the five drums contained waste oil and one drum contained <br /> waste solvent. The drums were not labeled, nor did they have an <br /> accumulation start date. <br /> Finally, Mr. Mannor showed Ambacher, Oz and I the area where the zinc <br /> phosphate sludge was passed through a filter press to be concentrated <br /> into filter cake consisting of 60-70% zinc and iron phosphate and 20- <br /> 40% water. At that time, the bulk storage transport bin for zinc <br /> phosphate was inspected. The zinc phosphate cake is allowed to <br /> accumulate until bin is full and then it is shipped to J.R. Simplot <br /> for reuse in fertilizer. <br /> IX DISCUSSION WITH MANAGEMENT <br /> After finishing the inspection, Ambacher, Oz and I returned to the <br /> conference room. Mr. Mannor requested that the inspection report be <br /> mailed to 1412 E1 Pinal, Stockton, CA. , 95205. <br /> With the inspection completed, Ambacher, Oz and I left the premise. <br />
