Which federal agency is responsible for enforcing the Clean Air Act?

The Environmental Protection Agency (EPA) is the federal agency tasked with implementing and enforcing the Clean Air Act. This landmark piece of legislation was established to regulate air emissions from both stationary and mobile sources, thereby ensuring that air quality meets health standards to protect citizens and the environment.

The EPA conducts research, sets national standards for air quality, and monitors compliance with these regulations. It also has the authority to issue permits for facilities that emit pollutants into the air and can enforce penalties against violators. The agency plays a crucial role in managing air pollution, addressing issues related to greenhouse gas emissions, and implementing programs aimed at improving air quality nationwide.

In contrast, the other options do not have this specific mandate. The Federal Environmental Authority is not a recognized federal entity within the context of environmental regulation in the U.S. The Department of Energy primarily focuses on energy production and management rather than directly regulating air quality. OSHA is concerned with workplace safety and health regulations, rather than environmental air quality issues.
