HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 5. Environmental Analysis AIR QUALITY standards and highlights the significant amount of reductions needed and the urgent need to engage in interagency coordinated planning to identify additional strategies, especially in the area of mobile sources, to meet all federal criteria air pollutant standards within the timeframes allowed under the CAA. The 2012 AQMP demonstrates attainment of federal 24hour PM25 standard by 2014 and the federal 8 -hour ozone standard by 2023. It includes an update to the revised EPA 8 -hour ozone control plan with new commitments for short -term NO, and VOC reductions. The plan also identifies emerging issues of ultrafne (PM3 o) particulate matter and near- roadway exposure, and an analysis of energy supply and demand. Lead State Implementation Plan The SoCAB, except for the Los Angeles County nonattainment area, remains in attainment of the new standard. On May 24, 2012, CARB approved the state implementation plan (SIP) revision for the federal lead standard, which the EPA revised in 2008. Lead concentrations in this nonattainment area have been below the level of the federal standard since December 2011. The SIP revision was submitted to EPA for approval. NonattalnmentAreas The AQMP provides the framework for air quality basins to achieve attainment of the state and federal ambient air quality standards through the SIP. Areas are classified attainment or nonattamment for particular pollutants, depending on whether they meet ambient air quality standards. Severity classifications for ozone nonattainment range from marginal, moderate, and serious to severe and extreme. Transportation conformity for nonattainment and maintenance areas is required under the federal CAA to ensure federally supported highway and transit projects conform to the SIP. The EPA approved California's SIP revisions for attainment of the 1997 8 -hour 03 National AAQS for the SoCAB in March 2012. Findings for the new 8 -hour 03 emissions budgets for the SoCAB and consistency with the recently adopted 2012 Regional Transportation Plan/Sustainable Communities Strategy (RTP /SCS) were submitted to the EPA for approval. The attainment status for the SoCAB is shown in Table 5.2 -2. The SoCAB is also designated in attainment of the California AAQS for sulfates. The SoCAB will have to meet the new federal 8 -hour 03 standard by 2023, and the federal 24 hour PM25 standards by 2014 (with the possibility of up to a five -year extension to 2019, if needed). SCAQMD has recently designated the SoCAB nonattainment for NO2 (entire basin) and lead (T.os Angeles County only) under the California AAQS. October 2014 Page 5.2 -9
