Secondary Lead Smelters: New Source Performance Standards (NSPS)
The secondary lead smelting industry consists of facilities that recycle lead-bearing scrap material, typically lead acid batteries, into elemental lead or lead alloys.
The promulgated standards limit emissions of particulate matter (1) from blast- (cupola) and reverberatory furnaces to no more than 50 mg/dscm (10.022 gr/dscf) and to less than 20 percent opacity, and (2) from pot furnaces having charging capacities equal to or greater than 250 kilograms to less than 10 percent opacity.
