IV. BACKGROUND• <br /> Silgan Containers Corporation has been operating at this <br /> location since the date it was purchased from Carnation in <br /> 1984 . <br /> On October 4, 1989, San Joaquin County Office of Emergency <br /> Services contacted PHS-EHD to report a hazardous material <br /> spill of approximately 100 gallons of gold epoxy coating at <br /> this site. William Snavely, Senior R.E.H.S. , PHS-EHD, <br /> responded to the spill. The spill occurred on the <br /> warehouse floor and was cleaned up with an absorbent and <br /> hauled as hazardous waste by Romic Chemical Corporation, <br /> 2081 Bay Road, East Palo Alto, CA, 94303 (Manifest <br /> #89894698) . <br /> On September 5, 1990, Silgan Container reported to PHS-EHD <br /> a solvent spill that occurred on September 4 , 1990 <br /> (Complaint #90-1648) . The spill was contained with an <br /> absorbent and later hauled off site as a hazardous waste. <br /> On February 8, 1990, a routine inspection was performed by <br /> Kasey Foley, Lead Senior, R. E.H. S. , PHS-EHD, and Dimetra <br /> Papadogionis, E.H. S. , PHS-EHD. <br /> V. GENERAL DESCRIPTION OF FACILITY: <br /> Silgan Containers Corporation manufactures metal cans for <br /> the use of food storage. The manufacturing process of the <br /> cans begins with sheets of tin that are coated with enamel. <br /> The coated tin sheets are then packed in ovens to bake the <br /> enamel onto the metal. This process is referred to as <br /> "curing" . After the sheets of tin are cured, they are <br /> either shipped to another can manufacturing plant for <br /> fabrication or are fabricated on site. The on site <br /> fabrication process involves cutting the tin plate sheets <br /> into cylindrical can shapes referred to as "body blanks" . <br /> The body blanks are then welded and an enamel coating is <br /> applied to the welded area. The enamel coating is referred <br /> to as a "side stripe" and is applied to prevent the tin <br /> from coming in contact with the food. The cylinders are <br /> then baked in an oven to "cure" the side stripe. Once the <br /> cylinders are cured, one end is mechanically placed on the <br /> cylinder by crimping the tin surfaces together. <br /> VI. HAZARDOUS WASTE ACTIVITY DESCRIPTION: <br /> 1. The application of the side stripe placed on the cans <br /> generates a hazardous waste liquid that is composed of <br /> enamel sludge and methylethyl ketone (M. E.K. ) solvent. <br /> The waste is referred to as "waste stripe" . In 1990, <br /> 78 tons of this waste was manifested to Romic Chemical <br /> 2 <br />
