Which agency is responsible for enforcing federal environmental protection laws?

The Environmental Protection Agency, or EPA, is the federal agency specifically created to enforce environmental protection laws in the United States. Established in 1970, the agency plays a crucial role in regulating pollutants, overseeing waste management practices, and ensuring compliance with various environmental statutes, such as the Clean Air Act and the Clean Water Act. Its mandate is to protect human health and the environment, making it the primary authority in matters related to environmental regulations and enforcement.

The other agencies listed in the question focus on different areas. The Food and Drug Administration is responsible for protecting public health by ensuring the safety of food and pharmaceuticals, while the Occupational Safety and Health Administration focuses on workplace safety and health regulations. The Federal Energy Regulatory Commission regulates interstate transmission of electricity, natural gas, and oil but does not focus on general environmental compliance. Therefore, the EPA is uniquely positioned as the agency for enforcing federal environmental laws.
