The original Clean Air Act was established in 
1963
.  It
established funding for the study and the cleanup of air
pollution.
In 
1970
 Congress created the Environmental Protection
Agency (EPA) and gave it the primary role in carrying out the
law.
In 
1990
, Congress revised and expanded the Clean Air Act,
Provided the  EPA even broader authority to implement
and enforce regulations reducing air pollutant emissions.
Placed an increased emphasis on more cost-effective
approaches to reduce air pollution.

Since 1970, the six commonly found air
pollutants have decreased by more than 50
percent.

Thermal inversion occurs when a layer of warm air
settles over a layer of cooler air that lies near the
ground. The warm air holds down the cool air and
prevents pollutants from rising and scattering.

Air pollution poses a significant threat to human health, the environment, and the economy. The Clean Air Act has played a crucial role in reducing air pollutants since its establishment in 1963. Criteria air pollutants such as ozone, particle pollution, carbon monoxide, lead, sulfur dioxide, and nitrous oxides are major contributors to air pollution. Thermal inversions like those seen in Salt Lake Valley can exacerbate pollution levels. It's essential to educate and engage in efforts to reduce air pollution through energy conservation and mindful transportation practices.
