Port of Los Angeles Baseline Air Emissions Inventory. <br />4.6.2.1 BAAQMD PROJECT -LEVEL SIGNIFICANCE CRITERIA <br />The BAAQMD CEQA Air Quality Guidelines were prepared to assist in the evaluation of air quality impacts <br />of projects and plans proposed within the Bay Area. The guidelines provide recommended procedures for <br />evaluating potential air impacts during the environmental review process and include recommended <br />thresholds of significance, mitigation measures, and background air quality information. They also include <br />recommended assessment methodologies for air toxics, odors, and GHG emissions. In June 2010, the <br />BAAQMD's Board of Directors adopted CEQA thresholds of significance and an update of the CEQA <br />Guidelines. In May 2011, the updated BAAQMD CEQA Air Quality Guidelines were amended to include a <br />risk and hazards threshold for new receptors and modified procedures for assessing impacts related to <br />risk and hazard impacts. <br />On March 5, 2012, the Alameda County Superior Court issued a judgment finding that the BAAQMD had <br />failed to comply with CEQA when it adopted the thresholds of significance in the BAAQMD CEQA Air <br />Quality Guidelines. The court did not determine whether the thresholds of significance were valid on their <br />merits, but found that the adoption of the thresholds was a project under CEQA. The court issued a writ <br />of mandate ordering the BAAQMD to set aside the thresholds and cease dissemination of them until the <br />BAAQMD complied with CEQA. <br />Following the court's order, the BAAQMD released revised CEQA Air Quality Guidelines in May 2012 that <br />included guidance on calculating air pollution emissions, obtaining information regarding the health <br />impacts of air pollutants, and identifying potential mitigation measures, and which set aside the <br />significance thresholds. The BAAQMD recognizes that lead agencies may rely on the previously <br />recommended Thresholds of Significance contained in its CEQA Guidelines adopted in 1999. The Alameda <br />County Superior Court, in ordering BAAQMD to set aside the thresholds, did not address the merits of the <br />science or evidence supporting the thresholds. The City finds, therefore, that despite the Superior Court's <br />ruling, and in light of the subsequent case history discussed below, the science and reasoning contained in <br />4.6-16 DECEMBER 2014 <br />
