EPA is proposing amendments to the national emission standards for hazardous air pollutants (NESHAP) for Primary Lead Smelting to address the results of the residual risk and technology reviews conducted as required under sections 112(d)(6) and (f)(2) of the Clean Air Act (CAA). These proposed amendments include revisions to the emission limits for lead, the addition of a lead concentration in air standard, and the modification and addition of testing and monitoring and related notification, recordkeeping, and reporting requirements. We are also proposing to revise provisions addressing periods of startup, shutdown, and malfunction to ensure that they are consistent with a recent court decision. Finally, we are proposing revisions to the rule’s applicability provision to make it consistent with the definition of the source category and proposing other minor technical changes to the standard. We are also responding to a petition for rulemaking filed on the standard with regard to lead as a surrogate and regulation of volatile organic compounds (VOC) and acid gases.
