<br />Euc~id Street Zone Change/Subdivision ER 2005-138 <br /> <br />The proj ect site is located wi thin the South Coast Air <br />Basin and subject to the requirements of the Clear Air Act <br />at both the Federal and State level, as implemented by the <br />South Coast Air Quality Management District. The South <br />Coast Air Quality Management Plan (AQMP) is the primary <br />planning document to monitor if air quality standards and <br />objectives are being achieved in the South Coast Air Basin. <br />The air quality objectives in the AQMP are based upon <br />population and growth projections provided in regional <br />planning programs and local general plans. A project could <br />be in conflict with the AQMP if it results in population <br />and growth impacts beyond those identified in regional <br />planning programs and/or local general plans. <br /> <br />The proposed proj ect is consistent with the General Plan <br />and its associated growth projections. Therefore, the <br />proposed project would be considered to be consistent with <br />the growth projections and air quality objectives <br />established in the South Coast AQMP. <br /> <br />B. Violate any stationary source air quality standard or <br />contribute to an existing or proposed air quality <br />violation? <br /> <br />Potentially Significant Unless Mitigation Incorporated <br /> <br />As mentioned previously, the South Coast Air Quality <br />Management District (SCAQMD) regulates air quality <br />pollutants in the South Coast Air Basin. Pollutants for <br />which ambient standards have been established are referred <br />to as criteria pollutants. Criteria pollutants include <br />Ozone (03), Carbon Monoxide (CO), Nitrogen Dioxide (N02), <br />Sulfur Dioxide (S02), and Particulate Matter (PMIO). The <br />South Coast Air Basin is currently a non-attainment area <br />for Ozone and Particulate Matter. The SCAQMD considers an <br />air quality impact to be significant if it exceeds the <br />criteria pollutant thresholds identified in the Table A-I. <br /> <br />Table A-I <br />EMISSION THRESHOLDS OF SIGNIFICANCE <br /> <br /> Project <br />Pollutant Construction Tons/ Operations <br /> Pounds/Day Quarter Pounds/Day <br />Carbon Monoxlde 550 24.75 550 <br />Reactive Organic <br />Compounds 75 2.5 55 <br /> <br />4 <br /> <br />75A-23 <br />
