What legislative act is primarily responsible for addressing lead hazards in housing?

The Lead-Based Paint Hazard Reduction Act is specifically designed to address lead hazards in housing, particularly where children may be exposed to lead-based paint and dust. This act places requirements on the disclosure of known lead-based paint hazards in residential properties and mandates certain actions for the remediation and management of lead hazards. Its primary goal is to protect public health, particularly the health of children, by reducing exposure to lead in homes built before 1978, when the use of lead-based paint was banned in residential properties.

In contrast, the other acts listed focus on different environmental or health issues. The Safe Drinking Water Act governs water quality standards for drinking water, the Clean Air Act focuses on air pollution control, and the Toxic Substances Control Act regulates the use of specific hazardous substances but does not specifically target lead hazards in residential housing. This specificity makes the Lead-Based Paint Hazard Reduction Act the most appropriate choice for addressing lead hazards in the context of housing.
