How the Clean Air Act Reduces

How the Clean Air Act Reduces Air Pollution Such as Particle Pollution and Ground-level Ozone

First, EPA works with state governors and tribal government leaders to identify "nonattainment" areas where the air does not meet allowable limits for a common air pollutant. States and tribes usually do much of the planning for cleaning up common air pollutants. They develop plans, called State/Tribal Implementation Plans, to reduce air pollutants to allowable levels. Then they use a permit system as part of their plan to make sure power plants, factories, and other pollution sources meet their goals to clean up the air.
