City of Santa Ana Environmental Checklist Pollutant Averaging Time CAAQSa NAAQSb Notes: a The California Ambient Air Quality Standards (CAAQS) for 03, CO, S02 (1-hour and 24-hour), NO2, PM10, and PM2s are values not to be exceeded. All other California standards shown are values not to be equaled or exceeded. b The NAAQS, other than 03 and those based on amoral averages, are not to be exceeded more than once a year. The 03 standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above the standard is equal to or less than 1. r ppm = parts per million by volume; ppb = parts per billion; Vg/M3 = micrograms per cubic meter.

State California Clean Air Act The California Clean Air Act (CCAA), signed into law in 1988, requires all areas of the state to achieve and maintain the California Ambient Ali, Quality Standards (CAAQS) by the earliest practical date. The CAAQS incorporate additional standards for most of the criteria pollutants and set standards for other pollutants recognized by the state. In general, the California standards are more health protective than the corresponding NAAQS. California has also set standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particles. The Basin is in compliance with these California standards for sulfates, hydrogen sulfide, visibility-reducing particles, and vinyl chloride. Table 3-2 details the current NAAQS and CAAQS, and Table 3-3 provides the Basin's (Orange County portion) attainment status with respect to federal and state standards. Local South Coast Air Quality Management District SCAQMD has adopted a series of air quality management plans (AQMPs) to meet the CAAQS and NAAQS. These plans require, among other emissions-reducing activities, control technology for existing sources, control programs for area sources and indirect sources, a SCAQMD permitting system designed to allow no net increase in emissions from any new or modified (i.e., previously permitted) emission sources, and transportation control measures. The 2007 AQMP was adopted on tune 1, 2007 (SCAQMD 2007), and is currently in the process of being updated.
