Clean Air Act (CAA) of 1970 and 1990- protect and improve the Clean Air Act (CAA) of 1970 and 1990- protect and improve the nation’s air qualitynation’s air quality
CAA requires development of State Implementation Plan (SIP) & CAA requires development of State Implementation Plan (SIP) & requires fed actions to conform to SIP’s purposerequires fed actions to conform to SIP’s purpose
SIP- Defines how States will comply with CAA and improve AQ SIP- Defines how States will comply with CAA and improve AQ (requires demonstration of “conformity”)(requires demonstration of “conformity”)
Conformity- project must not cause new AQ violation, worsen Conformity- project must not cause new AQ violation, worsen existing violation, or delay timely attainmentexisting violation, or delay timely attainment
