Proposed Amended Rule 1420 - Emissions Standard for Lead

EA - Environmental Assessment

Document Description
PAR 1420 has been developed to reduce public health impacts from point and fugitive lead emissions from metal melting or lead processing facilities by reducing the exposure to lead, and to ensure and maintain attainment of the National Ambient Air Quality Standard for lead within the South Coast Air Basin. PAR 1420 proposes an initial ambient air lead concentration limit of 0.150 micrograms per cubic per meter averaged over any consecutive 30 days which will be lowered to a final limit of 0.100 ug/m^3 by January 1, 2021. PAR 1420 also proposes requirements for point source lead emission controls, along with periodic source testing, capture efficiency testing, conditional ambient air monitoring, and reporting and recordkeeping requirements to ensure continuous compliance. Fugitive lead emissions will be addressed through housekeeping and maintenance activity requirements and total enclosures of areas where lead processing operations and associated processes are being conducted. Any facility that exceeds the limits in PAR 1420 will be subject to additional mitigation requirements. Some sites affected by PAR 1420 may be identified on lists compiled by DTSC per code section 65962.5. The analysis of PAR 1420 in the draft EA did not result in the identification of any environmental topic areas that would be significantly adversely affected.
