What You'll Learn
Implement the Clean Air Act
The Clean Air Act (CAA) is the United States' primary federal air quality law, aimed at reducing and controlling air pollution across the nation. The Act was first enacted in 1963 and has been amended multiple times since. The Clean Air Act outlines the responsibilities of the Environmental Protection Agency (EPA) in protecting and improving the air quality and the stratospheric ozone layer.
The Clean Air Act calls for state, local, tribal, and federal governments to work in partnership with the EPA to implement the Act and reduce pollution. The Act grants the EPA the authority to establish National Ambient Air Quality Standards (NAAQS) to protect public health and welfare, and to regulate emissions of hazardous air pollutants. These standards govern the allowable amounts of ground-level ozone, carbon monoxide, particulate matter, lead, sulfur dioxide, and nitrogen dioxide in the outdoor air.
To achieve these standards, states are responsible for developing enforceable state implementation plans (SIPs) that address specific industrial sources within their borders. These plans must also prohibit emissions that significantly contribute to air quality issues in downwind states. The EPA provides guidance, technical assistance, and reviews state plans to ensure compliance with the Act.
The Clean Air Act also includes specific programs to address various air pollution issues. For example, the Acid Rain Program (ARP) is an emissions trading program aimed at reducing sulfur dioxide and nitrogen oxide emissions from power plants, which are the primary contributors to acid rain. The CAA Ozone Program focuses on phasing out the use of chemicals that harm the ozone layer, such as chlorofluorocarbons and hydrofluorocarbons.
Additionally, the Clean Air Act addresses emissions from both stationary and mobile sources. For instance, the National Clean Diesel Campaign and the Diesel Emissions Reduction Program aim to reduce emissions from vehicles and engines by deploying cleaner-burning gasoline and pollution-controlling technologies. The Act also regulates emissions from major industrial facilities, with a particular focus on reducing toxic emissions.
