The South Coast Air Quality Management District (SCAQMD) held its first Working Group Meeting on May 2, 2018 for Proposed Rule (PR) 1480 - Air Toxic Metals Monitoring. PR 1480 aims to look at all current SCAQMD rules that include toxic metals monitoring requirements and create a comprehensive rule to which future air toxics rules could refer. As a result, SCAQMD would have more current and consistent sampling methodologies across all programs.

PR 1480 would take into account the existing rules with monitoring requirements for toxic metals including the following:

  • Rule 1156 - Hexavalent chromium from cement manufacturing facilities,
  • Rule 1420 - Lead from any metal melting or lead processing facility,
  • Rule 1420.1 - Lead from large lead-acid battery recycling facilities,
  • Rule 1420.2 - Lead from metal melting facilities, and
  • Rule 1466 - PM from solid with toxic air contaminants.

A few of the considerations for PR 1480 include applicability determinations, triggers, ambient concentration limits, ambient monitoring plans, length of monitoring, and costs. A second Working Group Meeting will be held in late Spring or early Summer 2018. The Governing Board Hearing is expected to occur in Fall 2018.
