Chemical Manufacturers Industry Overview Chemical manufacturers produce a large variety of hazardous wastes that might be subject to Resource Conservation and Recovery Act (RCRA) requirements covering the generation, transportation, and management of hazardous waste. Your business is included in the chemical manufacturers category if you manufacture: • Industrial inorganic chemicals • Industrial organic chemicals • Pigments • Plastics • Pesticides • Synthetic rubber • Explosives • Synthetic fibers • Gum and wood chemicals. Hazardous Wastes from Chemical Manufacturing The many different processes used in the chemical manufacturing industry result in a large number of specific wastes. Typical wastes from chemical manufacturing plants include spent solvents, distillation bottoms and side-cuts, off- specification or unused chemicals, wastewater, wastewater treatment sludge, emission control sludges, filter cake, spent catalysts, byproducts, reactor cleanout wastes, and container residues. Many wastes from chemical manufacturing (e.g., spent solvents and off-specification chemicals) are listed wastes. Toxicity Characteristic Leaching Procedure (TCLP) toxic constituents have been detected in many other chemical manufacturing wastes. Table 1 provides a general description of chemical manufacturing waste types. If you generate more than 100 kilograms (220 pounds or about half of a 55-gallon drum) of hazardous waste per month, you must complete a Uniform Hazardous Waste Manifest when you ship your waste. The Manifest requires the DOT (Department of Transportation) description of the waste, including shipping name, hazard class, and UN/NA ID number. This information can be found in Table 2 for a number of wastes that chemical manufacturers might generate. Table 1 and Table 2 are not comprehensive lists. If you suspect that you generate a hazardous waste that is not on this list, contact your state hazardous waste management agency or ' EPA Regional office for assistance. Waste Minimization An effective waste minimization program can reduce the costs, liabilities, and regulatory burdens of hazardous waste man- agement, while potentially enhancing efficiency, product quality, and community relations. Waste minimization techniques that can help you reduce the amount of hazardous waste that you generate include: • Production planning and sequencing • Process/equipment adjustment or modification • Raw material substitution • Loss prevention and housekeeping • Waste segregation and separation • Recycling. Training and supervision of employees implementing waste minimization techniques is an important part of your successful program.
