The U.S. Environmental Protection Agency (EPA) will hold a virtual public hearing on Thursday, October 16, 2025, to provide the public the opportunity to present comments and information regarding the Agency’s proposed amendments to the National Emission Standards for Hazardous Air Pollutants from Secondary Lead Smelting.
In this action, EPA is proposing:
- Maximum achievable control technology (MACT) floor-based total hydrocarbon (THC) and dioxin and furan (D/F) emissions limits from collocated rotary and reverberatory furnaces;
- Hydrochloric acid (HCl) and chlorine (Cl2) emissions as de minimis (therefore, do not require standards) from all furnaces;
- THC as a surrogate for carbonyl sulfide (COS) from all furnaces;
- Revisions to the differential pressure averaging time requirements;
- Alternate monitoring for demonstrating total enclosure at negative pressure;
- Removal of affirmative defense and associated provisions; and
- Updates to electronic reporting requirements and start-up, shutdown, and malfunction (SSM) requirements.
