Last Friday, the Department of Housing and Urban Development (HUD) issued a final rule amending HUD's lead-based paint regulations from 20 micro-grams of lead per deciliter of blood (µg/dL) to 5 in order to reduce blood lead levels in children under 6 years residing in federally-owned or assisted housing. The new rule is in alignment with the Centers for Disease Control and Prevention (CDC) blood lead threshold.
