When was the Clean Air Act originally established?

The Clean Air Act was originally established in 1963, marking a significant step in federal environmental legislation aimed at improving air quality in the United States. This act was the first comprehensive air quality legislation, which initiated a framework for regulating air pollutants and set the groundwork for subsequent amendments and expansions of the law. Over time, the Clean Air Act has been amended to strengthen standards and address a wider range of air pollution issues, including the incorporation of research findings and technological advancements in pollution control. While the Act has undergone many updates, the initial legislation laid the foundation for ongoing efforts to reduce air contamination and protect public health.
