Battery Manufacturing Effluent Guidelines
EPA promulgated the Battery Manufacturing Effluent Guidelines and Standards (40 CFR Part 461) in 1984 and amended the regulation in 1986. The regulation covers directdirect dischargerA point source that discharges pollutants to waters of the United States, such as streams, lakes, or oceans. and indirectindirect dischargerA facility that discharges pollutants to a publicly owned treatment works (municipal sewage treatment plant). dischargers. The Battery Manufacturing Effluent Guidelines and Standards are incorporated into NPDES permits for direct dischargers, and permits or other control mechanisms for indirect dischargers (see Pretreatment Program).

- Additional Information
Battery manufacturing encompasses the production of modular electric power sources where part or all of the fuel is contained within the unit and electric power is generated directly from a chemical reaction. There are three major components of a cell—anode, cathode, and electrolyte—plus mechanical and conducting parts such as case, separator, or contacts. Production includes electrode manufacture of anodes and cathodes, and associated ancillary operations necessary to produce a battery.
Water is used in battery manufacturing plants in preparing reactive materials and electrolytes, in depositing reactive materials on supporting electrode structures, in charging electrodes and removing impurities, and in washing finished cells, production equipment and manufacturing areas.
Wastewater is generated from many processes within the plants, including formation area washdown, plate curing, product rinsing, cooling, equipment and floor area washing, laboratory washing, hand washing, laundry, truck washing and wet scrubbers (air pollution controls). Regulated pollutants (varying by subcategory) include cadmium, chromium, cobalt, copper, cyanide, iron, lead, manganese, mercury, nickel, oil & grease, silver and zinc.
