Which government agency regulates deteriorated hazardous lead-based paint?

The Environmental Protection Agency (EPA) is the correct choice for regulating deteriorated hazardous lead-based paint. This agency is responsible for implementing and enforcing regulations that address environmental hazards, including lead in paint, dust, and soil. The EPA established the Lead-Based Paint Disclosure Rule and the Renovation, Repair and Painting (RRP) Rule, which seek to prevent lead exposure in children and vulnerable populations through the proper management of lead-based paint in residential and commercial properties.

The other agencies listed each have specific roles that do not primarily focus on the regulation of lead-based paint. For instance, the Department of Health might deal with public health implications of lead exposure but does not regulate hazardous lead in the same way as the EPA. OSHA focuses on workplace safety standards and may address lead exposure relevant to occupational environments but not specifically residential lead paint regulations. The CDC primarily works on public health and disease prevention rather than direct environmental regulation, although it does provide guidelines and information about lead exposure and health effects.
