Estimated construction emission levels of particulate matter <br />(PM,0) would exceed the South Coast Air Quality Management District's (SCAQMD) threshold <br />level of 150 ppd of PMm. <br /> <br />Finding <br /> <br />Finding 1: <br /> <br />Changes or alterations have been required in, or incorporated into, the project which <br />avoid or substantially lessen the significant environmental effect identified in the <br />Final EIR. <br /> <br />Facts in Support of the Findine <br />Temporary increase in construction-related emissions associated with PM,0 (not exhaust) will be <br />reduced by at least 50%, resulting in emissions of PM~0 equal to 92.8 ppd, through implementation <br />of the following mitigation measures that will reduce this impact to a less than significant level: <br /> <br />To minimize dust generated by construction operations, the applicant shall apply water or <br />dust suppressants to exposed earth surface during clearing, grading, earthmoving and other <br />site preparation work. Water shall be applied twice daily and dust suppression materials <br />should be applied as needed. <br /> <br />To minimize dust from construction vehicles, wheel washers shall be placed at the project <br />entrance at Main Street and vehicle wheels shall be hosed down prior to exiting on Main <br />Street. <br /> <br />Street sweeping of roads adjacent to the project site shall be done weekly by the contractor <br />during site grading to reduce fugitive dust from traffic. <br /> <br />The contractor shall plant all disturbed areas after the completion of site preparation <br />activities. <br /> <br /> TRANSPOR Tel TION AND C1R CULA TION <br /> <br />Significant Effect <br /> <br />Potential traffic safety impacts associated with site access and circulation may result at the project <br />entrance on Main Street. <br /> <br />Finding <br /> <br />l)iscoveO, Science (?enter EIR /lpril It), 1997 <br />City qf SYmta ~4na 8 S'tatement of Findings and Facts <br /> <br /> <br />
