Which federal agency is not responsible for regulating air quality laws?

The Food and Drug Administration (FDA) is the agency that is not responsible for regulating air quality laws. The primary mission of the FDA revolves around protecting public health by ensuring the safety and efficacy of food, drugs, cosmetics, and medical devices. While the FDA plays a vital role in public health and safety, its focus does not extend to environmental regulations, such as those pertaining to air quality.

In contrast, the Environmental Protection Agency (EPA) is directly responsible for regulating air quality through the enforcement of laws such as the Clean Air Act, which aims to protect human health and the environment from the effects of air pollution. The Department of Agriculture (USDA) primarily focuses on farming, agriculture, and nutrition policies, while the Occupational Safety and Health Administration (OSHA) is concerned with workplace safety, including occupational exposure to hazardous air pollutants. Therefore, the unique specialization of the FDA in food and drug regulation highlights why it does not engage with air quality laws.
