## 2.2. Clean Air Act 

The Clean Air Act (CAA) 4 and the Amendments (CAAA) set the overall policy for managing air quality across the nation. The CAA is comprised of seven major Titles, designed to promulgate and implement necessary regulations that would safeguard ambient air: 

• Title I: Provisions for Attainment and Maintenance of National Ambient Air Quality Standards – Establishes the framework by which outdoor air pollutant levels are measured, evaluated, and if required, reduced; 

• Title II: Provisions Relating to Mobile Sources – Gives EPA (and in some cases other federal agencies) the ability to establish emissions regulations for engines and fuels; 

• Title III: Air Toxics – Provides a mechanism to define, assess and control air toxics from major sources; 

• Title IV: Acid Deposition Control – Identifies special provisions for pollutant emissions that return to the earth in acidic rain, fog, or snow and are shown to damage ecosystems, and structures, and impact health; 

• Title V: Permits – Mandates eligible air emissions sources to secure and maintain an operating permit such that all applicable requirements of the CAA are met; 

• Title VI: Stratospheric Ozone and Protection of the Global Climate – Pursuant to the Montreal Protocol of 1990, identifies a timeline by which substances with stratospheric ozone depleting potential will be phased out; and 

• Title VII: Provisions Relating to Enforcement – Identifies a broad array of a uthorities and penalties designed to enhance the enforceability of the CAA. 

Of the seven Titles listed, the subjects discussed in subsequent sections of this Handbook pertain mostly to Titles I, II, and III .
