Its primary purpose is protecting public health and welfare via National Ambient Air Quality Standards (NAAQS) and technology-based controls. It uses **cooperative federalismEPA sets national floors, states implement through State Implementation Plans (SIPs).

    Key Components

    • NAAQS for six criteria pollutants (ozone, PM, CO, Pb, SO2, NO2) with primary/secondary standards.
    • Emission standardsNSPS** (§111), NESHAPs/MACT (§112), mobile source rules.
    • Permitting/enforcementTitle V** operating permits, NSR/PSD reviews, sanctions/FIPs.
    • Built on ambient outcomes, source controls, planning, and market-based programs (e.g., acid rain trading). No formal certification; compliance via permits and audits.
