The Clean Air Act (CAA) (42 U.S.C. 7401 et seq.) is a comprehensive Federal law that regulates all sources of air emissions.

Republic Act No. 8749, otherwise known as the Philippine Clean Air Act, is a comprehensive air quality management policy and program which aims to achieve and maintain healthy air for all Filipinos.

Today, as in the past, the Clean Air Act continues to cut pollution and protect the health of American families and workers. Fewer premature deaths and illnesses means Americans experience longer lives, better quality of life, lower medical expenses, fewer school absences, and better worker productivity.

EPA may assess civil administrative penalties of up to $37,500 per day, per violation against federal agencies for noncompliance. The total penalty cannot exceed $295,000 unless EPA and the Department of Justice determine a greater penalty is appropriate. EPA may also issue field citations against federal facilities.
