Levels of Regulation
, National Ambient Air Quality Standard for Lead (Lead NAAQS)
• 1.5 ug/m3 (current)
• 0.15 ug/m3 (adopted & beginning implementation)
, National Emission Standards for Hazardous Air Pollutants for Secondary Lead Smelters (Subpart X)
, California-specific rules:
, Rule 1420.1 • Early implementation of new Lead NAAQS
, Rule 1402 • Health Risk Assessment and Reduction

of lead emissions for other smelters compared to the lead emissions from the Quemetco City of Industry Faci lity. Forexample. for each pound of lead emitted by the Quemetco City of Industry Facility in California the Sanders Lead Facility in Alabama emits 86 pounds.
