Tucker <br /> ACCOMPANIED BY: Kent Zenobia and Renee Zollinger, Kleinfelder <br /> OBSERVATIONS AND COMMENTS: <br /> On 24 April 1989 an inspection was conducted of J-M Manufacturing Company, Inc. <br /> 1051 Sperry Road south of Stockton. Theo eration is a subsidiary of Formosa <br /> Plastics, USA, which is a subsidiary of Formosa Plastics Group. The Pipe Division <br /> was purchased from Johns-Manville in 1983. The organization was then split into i-a. <br /> Manufacturing Company, Inc. and J-M A/C Pipe Corporation. At that time the facility <br /> produced both asbestos/cement (A/C) pipe and poly vinyl chloride (PVC) pipe. A/C <br /> pipe manufacturing ceased in July 1987. <br /> The A/C pipe manufacturing process produced several types of waste including: <br /> project rejects, fully cured pipe and couplings not meeting specifications; process <br /> rejects, non-friable machine cleanings and rejected pipe prior to autoclaving; <br /> wrapping wastes, bags which had contained imported asbestos; and settling pond <br /> sediments, sediments from the process water discharged to two on site surface <br /> impoundments. The first three types of waste have been designated as not hazard-,),-: <br /> by the Department of Health Services (DHS). The pond sediments were also <br /> designated as not hazardous even though they contain greater than one percent <br /> asbestos, because the asbestos fibers are bound in a silica gel. <br /> The wastes listed above were disposed of in on-site landfills as shown on the attach,&-, <br /> map. After A/C pipe production was ceased in July 1987, the manufacturing <br /> equipment was shipped to China. Landfill K was the last landfill to receive waste an: <br /> it was covered with two feet of on site excavated soils in June 1988. The other landij'-. <br /> had been closed with two feet of soil cover prior to 1987. Landfills E and F were <br /> capped w4h two feet of imported clay. J <br />
