(c) Processes, operations, and activities generating the waste, with corresponding block diagram: See Appendix D. Star Buildings surface paints all structural members (steel beams) with a primer coating made of water-based paint. The coating operation complies with San Joaquin Valley Unified Air Pollution Control District Rule 4603, 5.1 (Surface Coating of Metal Parts and Products). The paint is categorized as high solids, lead and chrome free, air dry alkyds. The VOC • content of these paints as received,ready to apply, vanes from 95 to 105 grams per liter. An average total of 20,000 gallons of paint (2002), and primer, are used per year. Usage variations are due to changes in production levels. All paints are stored in closed, non-absorbent containers when not in use. Three painting processes are used: 900 gallon dip tank, a Vac-U-Paint Continuous Coating operation,and an Graco HVLP (High Volume, Low Pressure) spray system. The processes are alternative and not additive. Products that are dip painted are not hand sprayed and those products that are hand sprayed are not dip painted. The choice of method is determined by the size of the structural member and the specific color of primer requested by the customer. • In the dip tank processes, the structural member is immersed into the tank and coated with primer. It is then elevated (withdrawn) and allowed to drip-dry. Dip coating equipment complies with SJVUAPC District Rule 4603,5.5.6. • In the dip tank processes waste is generated by drips or spills that are swept up and collected when dry. • In the Vac-U-Paint Continuous Coater, the structural member is carried via conveyor through a paint reservoir and air-dried. The air and minute paint particles are pulled through an expansion chamber and filter cabinet utilizing a vacuum pump. The filtered air is then exhausted out of the building. The continuous coater complies with SJVUAPC District Rule 4102, 4.1 and District Rule 4603, 5.5. Paint that is not recycled back into the paint reservoir becomes hazardous waste. • In the Graco HVLP, hand spraying process,paint is delivered from a 55-gallon drum via rigid piping using high-volume, low-pressure spray coating equipment, and is normally consumed before the paint gets out of condition. The high-volume, low pressure spray equipment complies with SJVUAPC District Rule 4603, 3.20, and 4603, 5.5.3. In the hand-spraying process,there are wastes generated by overspray and dried paint in the drum if the paint has not been used completely. The over spray is then collected and stored for disposal. The waste is stored and disposed of in 30 cubic foot capacity Super Sack container. 7
