Lead Risk Management Activities
This page last reviewed April 22, 2010Inorganic lead was identified as a toxic air contaminant (TAC) in 1997. Once a substance is identified as a TAC, the ARB is required by law to determine if there is a need for further control. In the case of lead, ARB determined the best approach for addressing lead emissions from new and existing stationary sources was to develop risk management guidelines. The Lead Risk Management Guidelines:
- Establish a consistent site-specific risk assessment approach to evaluating potential lead risk by establishing step-by-step procedures for quantifying cancer health risks and non-cancer neurodevelopmental impairment health risks in children.
- Provide guidance on determining when to require application of the toxic best available control technology (T-BACT).
- Provide guidance on making decisions concerning the issuance of permits for new and modified stationary sources. and
- Provide guidance to the districts in setting public notification, significant risk and unreasonable risk levels for the Air Toxics "Hot Spots" Information and Assessment Act of 1987 (Hot Spots Program).
