3 EPA, Office of Solid Waste. Recycling of Wastewater Treatment Sludges from1 Electroplating Operations, f006 . 1997. September 19983F006 BENCHMARKING StudyEXECUTIVE SUMMARYThis report presents current information about the metal finishing industry in the , andis the result of a two year effort of the Metal Finishing WORKGROUP of the Common Sense Initiative(CSI). The CSI was begun by the Environmental Protection Agency (EPA) in 1994 to explore cleaner, cheaper, and smarter environmental strategies beyond those required by regulation.

4 Using the special authorities of the Federal Advisory Committee Act (FACA), EPA broughttogether representatives from federal, state, and local governments, industry, community-basedand national environmental interest groups, environmental justice groups and organized labor toexplore opportunities for managing environmental issues in new ways. Six industry sectors werechosen for the initial CSI efforts, including petroleum refining, automobile manufacturing, ironand steel production, electronics, printing and metal of the Metal Finishing Industry and Hazardous Waste finishing refers to processes which deposit or plate a thin layer of metal and/orapply an additional organic topcoat as an outer coating on products received from othermanufacturing operations.

5 Metal finishing is performed for either functional or decorativepurposes and affects many products we use everyday. For example, hard chrome plating is afunctional plating process that increases the hardness and durability of engine parts. Chromeplating automobile bumpers is an example of a decorative plating process. EPA estimated that there were approximately 13,400 metal finishing establishments in theUnited States. Of the total, approximately 10,000 metal finishing facilities are estimated to be captive shops contained inside a larger manufacturing operation.

6 The balance of 3,400 metalfinishing facilities are job shops or independent metal finishing operations that operate on ajob-specific contract basis. The total number of plating shops has decreased significantly since1the 1970's, mainly as a result of increasing regulations and competition. As in many manufacturing processes, some portion of the materials used in production orin the product itself are not totally captured as salable product, and exit the process inwastewater, solid waste, airborne emissions, scrap metal, or off-spec products.

7 Prior to 1980,there were no federal regulations covering the discharge or disposal of wastes from metalfinishing operations, and the wastes, which contained metals as well as other substances, wereoften directly discharged to surface waters or disposed of in landfills or lagoons. In 1980, EPA issued the Nation s first hazardous waste management regulations, which listed sludges from electroplating wastewater treatment as a hazardous waste ( f006 ), and setstandards for the storage, transportation, treatment and disposal of these sludges.

8 EPAsimultaneously developed regulations that require metal finishers to significantly reduce oreliminate pollutants in wastewaters discharged to publically owned wastewater treatment systems Borst, Paul A. EPA, Office of Solid Waste. Recycling of Wastewater Treatment Sludges from2 Electroplating Operations, f006 . 19984F006 BENCHMARKING STUDY (final pretreatment regulations were issued in 1986). As a result of the strengthening of the federal regulations, the metal finishing industryimplemented many improvements in material use, production processes and waste managementmethods.

9 Metals contained in f006 have commercial value if they are present in sufficientconcentrations and if other analytes in the sludge are below levels which would interfere with themetal recovery process. There may be other materials contained in the sludge which do notinterfere with metals recovery, but which could be hazardous if improperly managed. Theeconomics of hazardous waste management is a strong determinant of whether metal finisherssend sludges for land disposal or to recycling facilities. Estimates of the amounts of sludge thatare recycled or land disposed vary widely.

10 One source estimates that between 10 and 20 percentis recycled and between 80 and 90 percent is treated and land was this STUDY conducted?The CSI Metal Finishing Subcommittee focused on the metal finishing industry s beliefthat process improvements made by many metal finishers during the past 20 years havesignificantly changed the composition of the f006 material that was listed and regulated in 1980,and it is the industry s belief that modification of EPA s hazardous waste regulations for F006could increase the metal finishing industry s ability to recover and recycle more commerciallyvaluable metals from f006 than they currently recover.
