Conflict with or obstruct implementation of applicable Air Quality Attainment Plan or <br />congestion Management Plan? <br /> <br />No Impact <br /> <br />The City of Santa Ana is included within the South Coast Air Quality Management District and subject to <br />the requirements of the Clean Air Act at both the Federal and State level. The South Coast Air Quality <br />Management Plan (AQMP) is the primary planning document to monitor if air quality standards and <br />objectives are being achieved in the South Coast Air Basin. The air quality objectives in the AQMP are <br />based upon population and growth projections provided in the General Plan. A project could be in conflict <br />with the AQMP if it results in population and growth impacts beyond those identified in the City's General <br />Plan. The proposed project would not impact the growth projections in the General Plan. Therefore, <br />approval of the proposed zoning ordinance amendment would not be in conflict with the South Coast <br />AQMP. <br /> <br />B. Violate any stationary source air quality standard or contribute to an existing or proposed <br />air quality violation? <br />C. Result in a cumulatively considerable net increase of any criteria pollutant for which the <br />project region is non-attainment under an applicable federal or state ambient air quality <br />standard? <br />D. Expose sensitive receptors to substantial pollutant concentrations? <br />E. Create objectionable odors affecting a substantial number of people? <br /> <br />Less than significant impact <br /> <br />As mentioned previously, the South Coast Air Quality Management District (SCAQMD) regulates air <br />quality in the South Coast Air Basin. The South Coast Air Basin is currently a non-attainment area for <br />carbon monoxide, ozone, and particulate matter. The SCAQMD considers an air quality impact to be <br />significant if it exceeds the thresholds identified below. <br /> <br />EMISSION THRESHOLDS OF SIGNIFICANCE <br /> <br /> Project <br />Pollutant Construction Tons/ Operations <br /> Pounds/Day Quarter Pounds/Day <br />Carbon Monoxide 550 24.75 550 <br />Reactive Organic <br />Comoounds 75 2.5 55 <br />Nitrogen Oxides 100 2.5 55 <br />Particulate Matter <br /> 150 6.75 150 <br /> <br />Long-Term Operational Air Quality Impacts <br /> <br />The primary source of long-term operational emissions associated with the proposed project would be <br />generated by vehicle travel to and from the project site. A relatively minor amount of gaseous emissions <br />would also occur from natural gas and electricity usage. The proposed project is consistent with the City's <br />General Plan and would not exceed the air pollutant emission projections established in the General Plan <br />Land Use Element EIR. <br /> <br />31A~O <br /> <br />2 <br /> <br />
