The primary source of operational <br />emissions would be generated by vehicle travel to and from the <br />proj ect site. A relatively minor amount of gaseous emissions <br />would also occur from natural gas and electricity usage. <br /> <br />Using the South Coast Air Quality Management District CEQÞ. Air <br />Quality Handbook as guideline, the threshold for potentially <br />significant long-term air quality impacts would involve the <br />development of 166 single-family dwelling units. The proposed <br />project would be less than the threshold of significance for <br />long-term alr quality impacts established by the CEQA Air <br />Quality Handbook. Additionally, the proposed project lS <br />consistent with the General Plan and the long emissions <br />generated by the project are accounted for in the City's General <br />Plan Land Use Element EIR. <br /> <br />Short-term constructed Related Air Quality Impacts <br /> <br />Construction operations associated with the proposed project <br />could potentially result in short-term increases in particulate <br />mater, and to a lesser degree increases in carbon monoxide and <br />ozone. Peak day construction emissions for most pollutants would <br />occur during the clearing, excavation and grading phases. Using <br />the South Coast Air Quality Management District CEQA Air Quality <br />Handbook as a guideline, the threshold for potentially <br />significant short-term air quality impacts would involve the <br />grading of 1,309,000 sq-c.are feet of area. Þ~ssuming grading of <br />the entire proj ect site, approximately 43 J S6 0 square feet of <br />area would be graded. The proposed grading wo-c.ld be considerably <br />less than the threshold of significance established by the CEQA <br /> <br />5 <br /> <br />75BZ.S'Y <br />
