MacArthur Project Modification — Santa Ana - Air Quality Assessment KPC Environmental, Inc. 4.3.3 Additional Indicators Additional indicators to be considered when screening criteria to evaluate the need for further analysis with respect to air quality can be found in the SCAQMD's CEQA Handbook. The additional indicators noted by the SCAQMD are as follows: • Project could interfere with the attainment of the federal or state ambient air quality standards by either violating or contributing to an existing or projected air quality violation. • Project could result in population increases within the regional statistical area which would be in excess of that projected in the AQMP. Project could generate vehicle trips that cause a CO hot spot. • Project might have the potential to create or be subjected to objectionable odors that could impact sensitive receptors. • Project will have hazardous materials onsite and could result in an accidental release of air toxic emissions or acutely hazardous materials posing a threat to public health and safety. • Project could emit an air toxic contaminant regulated by District rules or that is on a federal or state air toxic list. • Project could involve burning of hazardous, medical, or municipal waste as waste -to- energy facilities. • Project could be occupied by sensitive receptors within a quarter mile or an existing facility that emits air toxics identified in District Rule 1401 or near CO hot spots. • Project could emit carcinogenic or toxic air contaminants that individually or cumulatively exceed the maximum individual cancer risk of 10 in 1 million. According to the SCAQMD if the project has significant air quality impacts, an Environmental Impact Report (EIR) should be prepared. If impacts of a project can be reduced to below the emissions significance levels through mitigation, then a Mitigated Negative Declaration (MND) can be prepared. The MND or EIR should use the methods recommended by the SCAQMD and ARB to quantify the levels of emission using the SCAQMD CEQA Handbook, LTRBEMIS, CALINE, and Emfac. All feasible mitigation measures to reduce emission to the lowest possible level should be identified and applied to the greatest extent possible. 02/02/11 11
