What I learned from Clean Air Primer:
1. The Federal Clean Air Act is the legislature that protects air quality standards in the U.S.
2. The six air pollutants that cannot be exceeded according to the National Ambient Air Quality Standards (NAAQS) are particulate matter, sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone, and lead. They are regulated because they have been proven to be harmful to humans over long periods of exposure.
3. All 50 states are part of the NAAQS, and if they do not meet the regulations, they must come up with a specific plan to control their emissions of dangerous pollutants.
4. The program put in place by the EPA is regulated by state and local agencies rather than the federal government.
