On October 17 and 18, 2023, the EPA and HUD will hold a virtual public workshop to receive stakeholder input on the detection, measurement and characterization of lead-based paint to support efforts to reduce lead exposure. EPA and HUD will use information received during the workshop to inform their joint effort to revisit the federal definition of lead-based paint and propose and finalize a revised definition, if necessary. The workshop will cover several topics related to low levels of lead in existing paint, including the potential health effects, the relationship between lead-based paint and dust-lead, possible exposure pathways (e.g., renovation and maintenance, deteriorating paint and direct ingestion), and emerging detection and measurement technologies used to quantify lead in paint. Additionally, EPA and HUD also seek any available new information on lead-based paint characteristics and medical evidence related to low levels of lead in paint to help with EPA and HUD's reevaluation of the definition of lead-based paint. The information shared will increase awareness of exposure pathways that must be considered, inform models that examine the exposure to lead at various concentrations and provide greater context for the impacts a lower definition may have.
