Stricter emission guidelines have been approved by the Californian air-quality management agency to regulate arsenic and other toxic substances from lead-acid battery recycling plants.
The revised targets mean Exide Technologies’ Vernon smelter plant and Quemetco’s battery recycling plant in Industry must adhere to new requirements from the South Coast Air Quality Management District (AQMD). The restrictions limit arsenic emissions to 11.3 kg per year until 2015 and 4.5 kg per year thereafter. Benzine emissions must be limited to 204 kg per year. The ambient concentration of arsenic cannot exceed 10 nanograms per cubic meter.
