Proposed Rule (PR) 1420.2 - Emissions Standards for Lead from Lead Melting Facilities

Proposed Rule (PR) 1420.2 - Emissions Standards for Lead from Lead Melting Facilities

PR 1420.2 would protect public health by reducing lead emissions produced by lead melting facilities. PR 1420.2 applies to metal melting facilities in the SCAQMD that melt 100 tons or more of lead annually. PR 1420.2 would accomplish this by limiting the ambient air lead concentration, establishing housekeeping and maintenance provisions, installing total enclosures, limiting the point source emissions, periodic source testing, and requiring ambient air lead sampling and monitoring. Owner/operators of affected facilities with an approved ambient air monitoring plan would be required to meet an ambient lead limit of 0.150 micrograms per cubic meter (ìg/m3) averaged over any 30 consecutive days effective September 4, 2015. For affected facilities without an approved ambient air monitoring plan, the same ambient lead limit will be effective 90 days after approval of the ambient air monitoring plan. Effective January 1, 2018, the limit would be further reduced to 0.100 ìg/m3 for all affected facilities. Improvements to building enclosures and additional control equipment may be necessary to comply with the proposed ambient standard. The proposed rule also requires implementation of a Compliance Plan if a facility exceeds an ambient air lead concentration of 0.100 ìg/m3 or a total facility mass lead emission rate of 0.080 lb/hr after January 1, 2018. The environmental analysis in the Draft EA concluded that PR 1420.2 would not generate any significant adverse environmental impacts. PR 1420.2 would affect six facilities that are on lists of California Department of Toxics Substances Control hazardous waste facilities per Government Code §65962.5 (http://www.envirostor.dtsc.ca.gov/public; accessed on July 16, 2015).
