The South Coast Air Quality Management District (SCAQMD) held a working group meeting on March 8, 2017 to discuss Proposed Amended Rule 1420 – Emissions Standard for Lead. The rule establishes lead emission limits for non-vehicular sources, including lead smelters and foundries.

The Proposed Amended Rule 1420 will include changes to the ambient lead concentration standard from 1.5 µg/m3 to 0.15 µg/m3 at the date of adoption. This corresponds with the 2008 revisions for the National Ambient Air Quality Standards for lead and is part of SCAQMD's 2012 State Implementation Plan. Additional proposed changes include updated point source requirements, source testing, and enclosure requirements. The amended rule is currently scheduled for a public hearing in October/November 2017.
