What Does Clean Air Act (CAA) Mean?
The Clean Air Act is a United States Federal Law that came into effect in 1963 to improve, strengthen and accelerate programs for the abatement of air pollution. The Act requires the Environmental Protection Agency (EPA) to develop and enforce regulations to protect the public from hazardous airborne contaminants. The Clean Air Act was the first major environmental law in the United States to include a provision for citizen law suits.
