City of Santa Ana <br />State <br />California Clean AirAct <br />Environmental Checklist <br />The California Clean Air Act (CCAA), signed into law in 1988, requires all areas of the state to achieve <br />and maintain the California Ambient Air Quality Standards (CAAQS) by the earliest practical date. <br />The CAAQS incorporate additional standards for most of the criteria pollutants and set standards for <br />other pollutants recognized by the state. In general, the California standards are more health <br />protective than the corresponding NAAQS. California has also set standards for sulfates, hydrogen <br />sulfide, vinyl chloride, and visibility- reducing particles. The Basin is in compliance with these <br />California standards for sulfates, hydrogen sulfide, visibility- reducing particles, and vinyl chloride. <br />Table 3 -2 details the current NAAQS and CAAQS, and Table 3 -3 provides the Basin's (Orange County <br />portion) attainment status with respect to federal and state standards. <br />Local <br />South Coast Air Quality Management Disti-ict <br />SCAQMD has adopted a series of air quality management plans (AQMPs) to meet the CAAQS and <br />NAAQS. These plans require, among other emissions- reducing activities, control technology for <br />existing sources, control programs for area sources and indirect sources, a SCAQMD permitting <br />system designed to allow no net increase in emissions from any new or modified (i.e., previously <br />permitted) emission sources, and transportation control measures. The 2007 AQMP was adopted on <br />June 1, 2007 (SCAQMD 2007), and is currently in the process of being updated. The 2012 AQMP <br />Advisory Group was approved by the AQMD Governing Board in September 2011, and was directed <br />to consider the following in updating the AQMP: latest scientific/ technological information and <br />planning assumptions (including the 2012 Regional Transportation Plan /Sustainable Communities <br />Strategy), updated emission inventory methodologies for various source categories, and a strategy <br />to implement zero or near -zero emission measures to reach attainment of particulate matter and <br />ozone standards. <br />SCAQMD adopts rules and regulations to implement portions of the AQMP. Several of these rules <br />may apply to construction or operation of the project. For example, SCAQMD Rule 403 requires <br />implementing the best available fugitive dust control measures during active operations capable of <br />generating fugitive dust emissions from onsite earth - moving activities, construction /demolition <br />activities, and construction equipment travel on paved and unpaved roads. <br />SCAQMD has published the CEQA Air Quality Handbook (November 1993) to help local governments <br />analyze and mitigate project - specific air quality impacts. This handbook provides standards, <br />methodologies, and procedures for conducting air quality analyses for CEQA documents, which, in <br />combination with up -to -date and current emissions factors, is used within the SCAQMD jurisdiction. <br />In addition, SCAQMD has published two additional guidance documents — localized Significance <br />Threshold Methodology for CEQA Evaluations (June 2003) and Particulate Matter (PM) 2.5 <br />Significance Thresholds and Calculation Methodology (October 2006) —that provide guidance for <br />evaluating localized effects from mass emissions during construction. Both were used in the <br />preparation of this analysis. <br />Regional Comprehensive Plan and Guide <br />The Southern California Association of Governments (SCAG) is the regional planning agency for Los <br />Angeles, Orange, Ventura, Riverside, San Bernardino, and Imperial Counties.
