Which agency is NOT involved in enforcing hazardous waste regulations?

The Food and Drug Administration (FDA) is primarily focused on ensuring the safety and efficacy of food products, pharmaceuticals, medical devices, and other biologics. Its role does not extend to the enforcement of hazardous waste regulations, which is outside its jurisdiction. Instead, agencies like the U.S. Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the Nuclear Regulatory Commission (NRC) are responsible for various aspects of hazardous waste management.

The EPA administers and enforces regulations related to hazardous waste under the Resource Conservation and Recovery Act (RCRA). OSHA establishes standards for workplace safety that can impact hazardous waste operations by ensuring worker protections in environments where hazardous materials are present. The NRC regulates materials that could be hazardous due to their radioactivity, ensuring safe handling and disposal of nuclear waste.

In this context, while many agencies play a critical role in the realm of hazardous materials and safety, the FDA's specific focus on food and drug safety makes it the agency that does not enforce hazardous waste regulations.
