California Clean Air Act
The California Clean Air Act (CCAA) of 1988 requires the air districts to endeavor to achieve and maintain the state ambient air quality standards by the earliest practicable date and develop plans for attaining the state ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide standards.
In compliance with the CCAA, the Sacramento Metropolitan Air Quality Management District prepared and submitted the 1991 Air Quality Attainment Plan (AQAP) to mainly address Sacramento County’s nonattainment status for ozone and carbon monoxide (CO), and although not required, particulate matter (PM10). The 1991 AQAP was designed to make expeditious progress toward attaining the state ozone standard and contained preliminary implementation schedules for control programs on stationary sources, transportation, and indirect sources, and a vehicle/fuels program.
Sacramento County meets the ambient air quality standards for sulfur dioxide, nitrogen dioxide and carbon monoxide. The Sacramento Region is currently designated nonattainment for ozone and particulate matter.
